What Is The Characteristic Of The Flexible Chain Conveyor's Sprocket?

The flexible chain conveyor can automatically carry out the continuous transportation of transportation, distribution and subsequent packaging. It is the best choice for enterprises to improve the efficiency of automated production. In the flexible chain conveyor, the chain plate and motor are more important. The conveyor manufacturer suggested that we use it together. Today we will specifically understand the other important structure of the flexible chain conveyor, the characteristics of the chain plate.

       1. The tooth shape of the sprocket

      The sprocket tooth shape must ensure that the chain energy-saving smoothly enters and exits the mesh, minimizes the impact and contact stress of the link during the meshing, and is easy to process.

      Commonly used sprocket face tooth profile. It is composed of three arcs aa, ab, cd and a straight line bc, referred to as a three arc-linear tooth shape. The tooth shape is machined with a standard tool. It is not necessary to draw the end face tooth shape on the sprocket work diagram. It only needs to be marked on the drawing; the tooth shape is manufactured according to the 3RGB1244-85 specification; however, the axial tooth profile of the sprocket should be drawn. The dimensions are referred to the design manual.

       2. Sprocket structure

       Commonly used sprocket structure. The small-diameter sprocket is generally made in one piece, and the medium-diameter sprocket is mostly made into a spoke type. In order to facilitate handling, loading and weight reduction, a hole is formed in the web, and the large-diameter sprocket can be made into a combination. Rings and wheel cores can be made from different materials! For example, C45, stainless steel and other materials.

       3. Sprocket material

       The sprocket material should ensure that the teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat treated to achieve a certain hardness.

       We now understand the characteristics of the chain conveyor sprocket, which is also very helpful for us to choose the sprocket of the chain conveyor.

What Is The Types And Specific Characteristics Of Flexible Conveyor Frames

The flexible conveyor frame is a steel structure that withstands rollers, rollers, conveyor belts, materials, and some cleaning devices and tensioning devices, and can withstand impact, tensile, compression, and bending stresses.

Flexible conveyor frames are available in both steel and flexible. The rigid frame can be used as a fixed and mobile frame, while the flexible frame main beam supports the roller, conveyor belt and material with wire rope, and the frame of the drive must be rigid.

According to different materials, it can be divided into:

(1) Steel structure frame. Use steel (such as channel steel, angle steel, I-beam) or special-shaped pipe steel.

(2) Steel pipe frame. The frame can be welded on the steel pipe. As a long-distance line, the ordinary seamless steel pipe can also be used as a frame; the steel pipe can be transported with water and oil, etc.

(3) Concrete frame. The vertical round tube belt conveyor frame made of concrete can reduce the maintenance work of rust removal, and the installation is convenient. The fixed long distance flexible conveyor is commonly used in this method. Both the nose and the tailstock can be prefabricated, and the bearing mounting holes are left.

(4) FRP rack. It has the characteristics of high strength, corrosion resistance and light weight, and is particularly suitable for transportation environments such as sea salt fields, mines, and chemical salt plants. Compared with the same weight, the price is slightly higher than that of steel, but considering the anti-rust cost of steel, the two are equal and have a large space for use.

Analysis Of The Disassembly Details Of The Flexible Chain

The flexible chain is an important equipment in the conveying system and is an indispensable part for the conveyor. Therefore, the flexible chain needs to be disassembled for maintenance and maintenance after a period of use. Since it is said that disassembly, there must be some demolition skills. Understand the disassembly skills in order to complete the chain removal safely and smoothly. The following we will introduce a few points about the disassembly of the flexible chain. I hope everyone can keep it in mind.

1. Turn the flexion of the flexible chain so that the piston is at the compression top dead center position, aligning the timing marks on the camshaft and the crankshaft sprocket. There are two timing marks on the camshaft sprocket, one is the timing mark when the first piston is at the top dead center, the valve and the exhaust valve are both in the closed position, and the second is when the second piston is at the top dead center. The timing mark, the valve and the exhaust valve are in the closed position. Be sure to find out where the pistons of the first few cylinders are at compression top dead center.

2. Remove the bolts on the camshaft sprocket and remove the timing chain and camshaft sprocket.

3. Install the timing flexible chain on the camshaft sprocket, fix the sprocket, suspend the chain, and align the timing marks on the camshaft and the crankshaft sprocket. Align the locating pin holes on the sprocket with the locating pin holes on the camshaft and attach the sprocket to the camshaft. The camshaft sprocket bolt tightening torque is 20N.

4. Turn the crankshaft two turns to check if the engine timing marks are aligned. If the timing marks are not aligned, follow the steps above to perform the flexible chain removal operation again.

With the rapid development of the industry, the use of flexible chains is becoming more widespread, more people are exposed to and understand the flexible chain, but its disassembly and use skills need to be carefully remembered by every staff member. Correct operation and use can ensure the stable operation of the equipment, making the work efficiency more stable and efficient.

How To Solve The Noise When The Conveyor Is Running?

When you use the conveyor, do you feel that the working sound is harsh when it is used? As a conveyor user, it is not good to live in this environment for a long time. At this time, we need to It carries out some improvements. Below we conveyor manufacturers to introduce a few common problems and solutions for everyone, I hope to be helpful to everyone.

1. Noise when the belt conveyor roller is severely eccentric When the belt conveyor is running, the roller often has abnormal noise accompanied by periodic vibration. Especially for the return roller, because of its large length, it is self-important and the noise is relatively large. There are two main reasons for noise. 

A. The wall thickness of the seamless steel pipe for manufacturing the idler is uneven, and the centrifugal force generated is large.

B. When machining, the center of the bearing hole at both ends is greatly deviated from the center of the outer circle, so that the centrifugal force is too large. Solution: Continue to use if the bearing is not damaged and noise is allowed.

      

2. The noise of the belt conveyor coupling between the two shafts is different. The noise is also generated at the coupling between the high-speed end motor of the drive unit and the reducer or the coupling with the brake wheel. It is accompanied by vibrations of the same frequency as the motor. Solution: The position of the motor reducer should be adjusted in time to avoid breakage of the input shaft of the reducer.

   3. The belt conveyor reverses the abnormal noise of the drum and the driving drum. When the reversing drum and the driving drum work normally, the noise is very small. When abnormal noise occurs, the bearing is generally damaged, and the bearing seat makes a rattle. Solution: Replace the bearing.

       If your conveyor has the above problems, then you can improve it according to the above method. I believe that the noise will not bother you after this.

The Basic Composition Of The Flexible Conveyor System You Need To Know

Flexible conveyor systems are of great use as a transportation device that is now widely used. If you want to use it skillfully, then you need to have a good understanding of it. Ask everyone a basic question. What are the basic components of a flexible conveyor system? If you can't answer this question, then you really have to understand it.

The basic structure of the flexible conveyor system:

(1) Conveyor chain: It is made of white and high-strength engineering. Can be divided into flat chain, universal chain, steel top chain, wedge chain, ball chain, brush chain, elastic chain and so on.

(2) Conveying crucible: consisting of an aluminum alloy profile with an anodized surface and a friction rail. Can be divided into standard type, enhanced type.

(3) Transport frame body: It is also composed of an aluminum alloy profile whose surface is anodized. Divided into light, medium and heavy.

(4) Drive device: consists of an aluminum drive head that is die-cast by powder metallurgy. Divided into single drive, dual drive and intermediate drive.

(5) Guide: A two-sided guardrail that allows the material to always run in the middle of the chain plate.

(6) Turning device: the inner supporting device when the chain plate turns. Divided into horizontal elbows, vertical elbows, horizontal elbows and horizontal wheels.

(7) Accessories: There are connectors, liquid trays, etc.

The above is the basic structure of the flexible conveyor system. If someone asks you this question again next time, then you should be able to answer it quickly.

How To Installate The Belt Conveyor

The installation of the belt conveyor is generally carried out in the following stages.

1. The installation of the rack frame of the belt conveyor starts from the head frame, then installs the intermediate frames in each section in sequence, and finally installs the tailstock. Before installing the rack, first pull the center line over the entire length of the conveyor. Since keeping the center line of the conveyor on the straight line is an important condition for the normal operation of the conveyor belt, it is necessary to install each section of the rack. Align the center line, and also set the shelf leveling. The tolerance of the frame to the center line is ±0.1mm per meter. However, the error on the center of the rack shall not exceed 35 mm over the entire length of the conveyor. Once all the blocks have been installed and aligned, the blocks can be connected.

2. Installation of the drive device: When installing the drive device, care must be taken to make the drive shaft of the belt conveyor perpendicular to the center line of the belt conveyor, so that the center of the width of the drive roller coincides with the center line of the conveyor, the axis and transmission of the reducer The axes are parallel. At the same time, all shafts and rollers should be leveled. The horizontal error of the shaft is allowed to be in the range of 0.5 to 1.5 mm depending on the width of the conveyor. At the same time as the driving device is installed, a tensioning device such as a tail wheel can be installed, and the drum axis of the tensioning device should be perpendicular to the center line of the belt conveyor.

3. Installation roller: After the frame, transmission and tensioning device are installed, the roller frame of the upper and lower rollers can be installed, so that the conveyor belt has a slowly changing arc, and the spacing of the roller cage of the bending segment is normal. The roller frame spacing is 1/2 to 1/3. After the roller is installed, it should be flexible and light.

4. Final alignment of the belt conveyor To ensure that the conveyor belt always runs on the centerline of the rollers and rollers, the following requirements must be met when installing the rollers, frames and rollers:

1) All rollers must be lined up, parallel to each other, and kept horizontal.

2) All the rollers are arranged in rows and parallel to each other.

3) The support structure frame must be straight and maintain horizontal. For this reason, after the drive roller and the roller frame are installed, the center line and level of the conveyor should be finally corrected.

5. Then secure the rack to the foundation or floor. After the belt conveyor is fixed, the feeding and unloading devices can be installed.

6. Hanging conveyor belt: When hoisting the conveyor belt, firstly spread the conveyor belt strip on the idler roller, and then hold the driving roller, then apply it on the roller of the heavy-duty section. Hanging the strip can use a 0.5-1.5t hand winch. When tightening the strap for connection, the roller of the tensioning device should be moved to the limit position, and the trolley and the screw tensioner should be pulled toward the transmission; and the vertical clamping device should move the roller to the uppermost position. . Before tightening the conveyor belt, the gear unit and the motor should be installed, and the tilting conveyor should be equipped with the brake device.

7. After the belt conveyor is installed, an idle test machine is required. In the idling test machine, attention should be paid to the presence or absence of deviation during the operation of the conveyor belt, the operating temperature of the driving part, the movement during the operation of the roller, the tightness of the cleaning device and the contact surface of the guide plate and the conveyor belt, etc. Make necessary adjustments, and all components are normal before the test can be run with load. If a screw-type tensioning device is used, the tightening degree should be adjusted once again when the test machine is operated with a load. If the roller is not horizontal, the conveyor belt will be deflected. If the installation is out of tolerance, the machine should be stopped and leveled; if the deviation of the outer diameter of the drum is too large, the outer circle of the roller should be reworked; the bonding material on the surface of the roller will cause the conveyor belt to deviate. These materials are often removed; the conveyor belt is offset when it is loaded, and the position of the inlet should be changed; the conveyor belt is deflected when there is no load, and the material can be corrected. This phenomenon is generally caused by too much initial tension, and can be appropriately adjusted.

Main Parameters Of Conveyor Equipment

The main parameters are generally determined according to the requirements of the material handling system, the various conditions of the material handling location, the relevant production process and the characteristics of the materials.

1 conveying capacity: The conveying capacity of the conveyor equipment refers to the amount of material conveyed per unit time. When transporting bulk materials, it is calculated as the mass or volume of material transported per hour; when transporting a single item, it is calculated as the number of pieces delivered per hour.

2 conveying speed: increasing the conveying speed can improve the conveying capacity. When the conveyor belt is used as the traction member and the conveying length is large, the conveying speed is increasing. However, high-speed belt conveyor equipment should pay attention to vibration, noise and start and brake problems. For conveyor equipment with a chain as the traction member, the conveying speed should not be too large to prevent an increase in the dynamic load. At the same time, the conveyor equipment for the process operation shall be determined according to the production process requirements.

3 Component size: The component dimensions of the conveyor equipment include conveyor width, slat width, hopper volume, pipe diameter and container size. These component sizes directly affect the conveying capacity of the conveyor equipment.

4 Delivery length and inclination: The length of the conveyor line and the angle of inclination directly affect the total resistance of the conveyor equipment and the required power.

What Is Conveyor Equipment?

Conveyor equipment is a material handling machine that continuously transports materials on a certain line, also known as continuous conveyor equipment. The conveyor equipment can be transported horizontally, obliquely and vertically, or it can form a space conveyor line, which is generally fixed.

The classification of conveyor:

The universal belt conveyor equipment consists of conveyor belts, rollers, rollers and devices for driving, braking, tensioning, reversing, loading, unloading and cleaning.

1. conveyor belt

Commonly used are rubber belts and plastic belts. The rubber band is suitable for working environment temperature between -15 ~ 40 °C. The material temperature does not exceed 50 °C. The upward spread of the bulk material is 12° to 24°. A patterned rubber band can be used for large angles of transport. The plastic belt has the advantages of oil resistance, acid and alkali, but has poor adaptability to the weather, and is easy to slip and age. Bandwidth is the main technical parameter of belt conveyor equipment.

2. roller

The single drum (the angle of the tape to the drum is 210 ° ~ 230 °), the double drum (wrapping angle of 350 °) and the multi-roller (for high power). There are grooved idlers, flat rollers, self-aligning rollers, and cushion rollers. The trough-shaped idler (consisting of 2 to 5 rollers) supports the bearing branch for conveying the loose material; the self-aligning roller is used to adjust the lateral position of the belt to avoid the deviation; the buffer roller is installed at the receiving position to Reduce the impact of the material on the belt.

3. rollers

The drive roller and the reverse roller are divided. The drive roller is the main component that transmits power. The single drum (the angle of the tape to the drum is 210 ° ~ 230 °), the double drum (wrapping angle of 350 °) and the multi-roller (for high power).

4. tensioning device

Its function is to bring the conveyor belt to the necessary tension to avoid slipping on the drive roller and to ensure that the deflection of the conveyor belt between the rollers is within the specified range.

Conveyor equipment can be divided into: according to the operation mode: 

1: belt conveyor equipment 

2: screw conveyor equipment 

3: bucket elevator

Common Failure Of Chain Conveyor Chain And Its Solution

The chain type used in chain transmission, rich product range, including transmission gear chain, chain CVT, long pitch conveyor chain, short pitch roller chain, double pitch roller chain conveyor chain, transmission speed, roller chain, heavy-duty drive plate bending roller chain, transmission, double pitch roller chain short pitch roller chain plate chain etc..

1, stainless steel chain

Stainless steel chain, as the name suggests, is a chain of stainless steel as the main casting material. The chain has good corrosion resistance and can adapt to the working environment of high or low temperature. The main applications of the stainless steel chain are the food manufacturing and processing industry, the chemical industry and the pharmaceutical manufacturing industry.

2. Self lubricating chain

The necessary material for self-lubricating chain is a special sintered metal that is filled with lubricating oil. The chain made of this metal has the ability of wear resistance and corrosion resistance, and can finish self lubrication, no need for maintenance, more convenient to use, and longer service life. The self lubrication chain is more suitable for high wear resistant and not easy to maintain, such asthe food automation production lineand so on.

3. Rubber chain

The rubber chain is made by adding a variety of rubber to the attached plate after adding U - shaped attached plate to the outer chain of the common chain.  The rubber used for rubber chain is mostly natural rubber NR or silicone rubber SI, etc., so that the chain can get better wear resistance and reduce noise in operation and increase anti vibration ability.

4. High strength chain

High strength chain is a special roller chain. It improves the shape of chain plate on the basis of original chain, and makes special treatment for chain plate, chain plate hole and pin shaft. The high strength chain has a good tensile strength, which is 15% to 30% higher than the tensile strength of the common chain, and has good impact resistance and fatigue resistance.

The failure types of chain conveyor chain are as follows: chain plate damage, transmission chain in the chain plank slot, transport chain on the power sprocket, shedding, link chain breakage and chain link damage.

a, most of the damage of the chain plate is excessive wear and bending deformation, and occasionally there is cracking. The main reasons are as follows: the uneven laying of the bottom plate of the chain plank machine or the bending angle beyond the design requirements; the joint of the chain plank machine is not good or partial deformation.

b, the chain transfer chain plate slot prolapse, the reasons are: the chain conveyor chain plate to tank bottom plate according to the design requirements in the laying of paving tile straight, but uneven, excessive bending; chain plate chain conveyor groove or serious wear, make the gap between the two is too large;

c, the power sprocket and the transmission chain can not be meshing normally, causing the transmission chain to fall off on the power sprocket, which is commonly known as the "tooth jumping" phenomenon. The main reasons are as follows: the dynamic sprocket is seriously worn or churned into the sundries, and the two chains are not consistent.

d, connection chain ring fracture. All our chain conveyor chain is connected with production in accordance with the relevant standards, the breaking load is about 10 times the chain plate can bear tension, safety factor, theory should not be broken chain accident, but the link failure rate in actual use is large, the study of its causes the main is: long time under pulsating load, fatigue failure in far below the breaking force, fracture, general connection link in the transition arc and line; manufacturing quality does not meet the standards, materials and heat treatment level does not pass;

e. The chain ring is damaged. In actual use, because the connecting link is usually larger than the conveying chain, the wear condition is also serious, so the connecting link has become the weak point in the whole transmission chain. It is the main damage form of serious wear, fracture, open, the reasons are: under pulsating load, long-term fatigue failure; the connecting pin or bolt loosening, supplement failed to find the link with uneven force or pull off.
