What Are The Four Major Mechanical Devices For Belt Conveyors?

#elevatedbeltcoveyors  #conveyorbeltsystem #conveyorbeltrollersdesign  #conveyorbelttrackingprocedure #foodgradebeltconveyor

The belt conveyor is a modern automation equipment, mainly through the development of automatic control, digital, networked controllers and sensors to achieve the delivery of various materials. The assembly line generally includes a traction member, a carrier member, a driving device, a tensioning device, a redirecting device, a support member, and the like. The belt conveyor can also be used to form a space conveyor line, which is generally fixed. The belt conveyor has a large conveying capacity and a long transportation distance. It can also complete several process operations simultaneously in the conveying process, and is widely used.

    The four major devices of the belt conveyor are the drive unit, the brake unit, the brake unit and the reversing unit. We will give a detailed introduction below. The first is the drive unit, which is undoubtedly the core of the entire belt conveyor. It has just been mentioned that the working principle of the belt conveyor is mainly realized by the friction transmission force, and the friction between the belt and the drum is generated by the motor and the speed reducer. The function of the drive device is to transmit friction to the conveyor belt, which in turn affects the transmission distance and the transport direction.

    Common brake devices include roller backstops, belt backstops, and tile brakes. This is a flexible addition based on the actual needs of the user. Its main function is to prevent the conveyor belt of the inclined upward movement from moving under the action of the cargo weight, causing the material to flow backward. Therefore, we say that the brake device under the belt conveyor parameters is very intelligent, especially suitable for material conveying at large dip angles.

    The belt conveyor is continuously and smoothly operated according to the friction transmission principle. When purchasing the belt conveyor, the customer will have a detailed understanding of the belt conveyor parameters according to the production needs of the relevant enterprises. Belt width, conveying length, conveying speed and conveying volume are all closely related to the belt conveyor parameters. The production capacity of the equipment is different depending on the parameters.

    Next we will talk about the tensioning device, which is divided into horizontal tension and vertical tension. The function of the tensioning device is to maintain the necessary initial tension of the conveyor belt to avoid slipping on the drive drum and to ensure that the sag of the conveyor belt is within the specified range. This is also to ensure the balance and continuity of the transfer process. The fourth important device of the belt conveyor, which we can see very clearly on the belt conveyor picture, is a roller set. The reversing device is generally at the end of the belt conveyor, and the belt is transported at different angles to reduce the transport pressure of the belt. The angle of the redirecting device is closely related to the diameter of the drum and needs to be adjusted on site according to the specific situation.

Do You Know The Design Parameters Of These Roller Conveyors And The Motor Failure Solution?

#rollerconveyor #nonpoweredrollerconveyor #powerrollerconveyor #rollerconveyorsystem #rollerspiralconveyor

The roller conveyor has a simple structure, high reliability, and convenient use and maintenance. Applicable to the transportation of all kinds of boxes, bags, pallets, etc., bulk materials, small items or irregular items must be placed on the pallet or in the tote. The roller conveyor is capable of transporting a single piece of material that is very heavy or subject to large impact loads. The structure of the roller conveyor is divided into two types according to the driving method: a non-powered roller conveyor and apower roller conveyor. When selecting the roller conveyor, the food industry should give priority to the all-stainless steel body and stainless steel drum.

    Before customizing the roller conveyor, we first need to determine the following roller conveyor parameters:

    (1) the length, width and height of the object conveyed by the roller conveyor;

    (2) the weight of each conveying unit of the roller conveyor;

    (3) the bottom condition of the conveyor conveyed by the roller conveyor;

    (4) Whether there are requirements for special working conditions;

    (5) The roller conveyor belongs to the unpowered or motor driven type.

    The most common fault of the roller conveyor is the problem of the motor. The motor is the heart of the whole mechanical equipment. A slight carelessness will cause the roller conveyor to be difficult to operate for normal operation. The failure to deal with it is on the one hand, on the other hand. It is necessary to carry out regular maintenance and maintenance in order to make the life of the roller conveyor longer, and bring better economic benefits to the production enterprise.

    The most common failure of a roller conveyor during operation is that the motor cannot start or slow down immediately after a normal start. There are generally four reasons for this:

    (1) May be caused by a line fault. Solution: Perform line inspection of the roller conveyor at the first time;

    (2) It may also be caused by a drop in voltage. Solution: Check the roller conveyor voltage to ensure normal;

    (3) There may also be a failure of the roller conveyor contactor. Solution: At this time, it is necessary to check the overloaded electrical appliance for timely replacement;

    (4) Another possibility is that the roller conveyor is continuously operated for a short time in a short time. Solution: At this time, we only need to reduce the number of operations to return the roller conveyor to normal start-up.

#clampingwasher #asteelsupporting #supportingframe #conveyorbracket

    In the industrial technology of the round tube rubber belt in the accessories of the conveyor equipment, we use the forming die and the round pipe pressing technology to rapidly shape the conveyor belt into a round pipe structure by heat vulcanization, and increase the conveying of the multi-layer fabric core inside. With a canvas layer, it can be seen from the analysis of the force at each point that such a structure has a higher level of resistance to flexing, and adopts a scientific manufacturing process to comprehensively improve the overall external resistance of the rubber conveyor belt, and is mainly used in industrial and mining production applications. It is used in the matching of round tube belt conveyors with different inclination angles;

    In addition, in the practical technology of the conveyor roller with clamping function, the structure is mainly composed of a clamping washera steel supporting piece and a connecting rod, and the protruding point is mainly to quickly press the rubber into a plurality of cushioning rubber rings. A clamping steel ring is installed at both ends of the drum, and a strong supporting frame is mounted on the main shaft, and the buffer rubber ring, the clamping bracket and the support frame are connected in series through the quenched connecting rod, in this way The belt drive roller is manufactured to ensure the satisfactory use of the special clamping type wear-resistant roller matched with the heat-resistant conveyor belt;

    Furthermore, how to make the endless conveyor belt have more precise correction technology, the transportation equipment manufacturer gives a more reasonable solution, the specific implementation method is: installing a sliding support at the bottom position of the beam on the belt conveyor frame. And the bearing set of the offset bearing type is welded on the main bearing mounting seat, the bearing seat can realize the smooth sliding of the front and rear, and then the rubber conveyor belt is penetrated in the inner groove of the adjusting roller set, and at the same time in the bearing One side of the seat is equipped with a large stroke cylinder, the cylinder joint is flexibly connected with the bearing seat, and a speed control valve is arranged at the outer edge of the nylon rubber belt. Through the design improvement of the above scheme, the heat resistant belt can be effectively controlled during the work process. The central deflection phenomenon enhances the comprehensive performance of the industrial belt machine;

    Finally, in the belt conveyor roller and its bracket interchange device, the manufacturing principle is mainly to machine two rectangular slots on the mating surface of the belt conveyor bracket fixing plate to make them perpendicular to each other. The straight slot is designed as a groove with an arc structure along the width direction of the fixing plate to start from the bolt mounting hole at the rightmost side of the fixing plate, and extends in an arc direction until the edge is penetrated into position, and the sound is heard By designing the product in this way, the manufacturer can completely improve the comprehensive interchange efficiency of the belt conveyor roller and its bracket, and fully meet the user's need for efficient operation in the field.

What Are The Common Types Of Chains?

#stainlesssteelchain #selflubricatingchain #sharpchain #sidebendchain

The transmission of the equipment is generally based on the chain, which everyone should know. Different types of chains will appear in different types of needs, and the role played will be different. So today, we will introduce the common types of chains.

    Stainless steel chain: The parts are made of stainless steel. This type of chain is suitable for use in the food industry and susceptible to chemical and pharmaceutical erosion. It can also be used in high and low temperature applications.

    Nickel-plated chain, galvanized chain, chrome-plated chain: All carbon steel materials can be surface treated. The surface of the parts is nickel-plated, galvanized or chrome-plated. It can be used in outdoor rain erosion, but it can not prevent thick Chemical liquid corrosion.

    Self-lubricating chain: Some parts are made of a sintered metal impregnated with lubricating oil. This chain has excellent wear resistance and corrosion resistance, no maintenance (maintenance-free) and long service life. Widely used in high-force, wear-resistant requirements, and can not be often maintained, such as food industry automated production lines, high-end bicycle racing, less maintenance high-precision transmission machinery.

    O-ring chain: O-ring seals are installed between the inner and outer chain plates of the roller chain to prevent dust from entering and the grease flowing out of the hinge. The chain is strictly pre-lubricated. Because the chain has superior parts and reliable lubrication, it can be used in open drives such as motorcycles.

    Rubber chain: This type of chain is a U-shaped attachment plate on the outer link of the A and B series chains. Rubber is attached to the attachment plate (such as natural rubber NR, silicone rubber SI, etc.) to increase wear resistance and reduce Noise, increase shock resistance. For transport.

    Sharp chain: This chain is widely used in the wood industry, such as the feeding and output of wood, cutting, conveyor transport and so on.

    Agricultural machinery chain: Agricultural machinery chain is suitable for field working machinery such as walking tractors, threshers, combine harvesters, etc. This type of chain requires low cost but can withstand impact and wear. In addition, the chain should be greased or automatically lubricated.

    High-strength chain: It is a special roller chain. It can improve the tensile strength by 15~30% and improve the impact performance by improving the shape of the chain plate, thickening chain plate, fine-punching chain plate hole and pin shaft heat treatment. Fatigue performance.

    Side Bend Chain: This chain has a large hinge clearance and chain plate clearance, so it has greater flexibility for bending drive and conveying.

    Escalator chain: used for escalators and automatic walkways. Due to the long working hours of the escalator, the safety requirements are high and the operation is stable. Therefore, it is required that the step chain must reach the specified smaller ultimate tensile load, the total length deviation of the two paired chains, and the step distance deviation.

    Motorcycle chain: defined by the purpose of the chain, from the structure of the chain, there are two types of roller chain and sleeve chain, from the part used on the motorcycle, it has two types of use inside the engine and outside the engine. Most of the chains used in the engine are sleeve chain structures. The chain used outside the engine is the drive chain for driving the rear wheels, and most of them use roller chains. Such chains should pay special attention to ensure fatigue performance.

    Agricultural clamping conveyor chain: suitable for walking wheat, rice harvesters and fixed motorized rice and wheat threshers, as well as semi-feeding combine harvesters

How To Identify If There Is Any Miscellaneous Material When Buying A Plastic Chain?

#plasticconveyorchains #chainlines #conveyingequipment #plasticchain

   Machinery is used in many places in life, and the effect is great. The machinery is generally driven by chains, and the chain is also diverse. Plastic conveyor chains are also one of them, but people should not be too small, and the effect is really great. However, the quality of plastic chains sold by manufacturers is different, there are good and bad, so people must be careful when buying, many plastic chains will be doped with miscellaneous materials, which will affect the quality. So how do we identify if it is doped with miscellaneous materials when buying plastic chains?

    First of all, it depends on whether the surface is flat or not, and the plastic chain made of miscellaneous materials is not flat. This is the obvious feature of the secondary material mixed injection molding.

    The second point is to see if the chain lines are smooth and smooth. Generally, the plastic chains made of new materials have the advantages of neat appearance, self-lubricating, etc., and the hand feels lubricated and not rough.

    Thirdly, in terms of use, the plastic chain made of miscellaneous materials can not achieve the original performance in application, such as being incapable of wearing and being easily broken, and the chain parts need to be replaced frequently.

    As an important part of the conveying equipment, the plastic chain carries an important part of material conveying or mechanical transmission. When purchasing plastic chains, we should pay attention to whether the plastic chain has quality problems. Keep in mind the above methods to identify high-quality plastic chains, so that your inferior products are getting farther and farther away from you.

Improvement Of The Belt Conveyor Tail Wheel

#beltconveyor #PUbeltconveyor #PUPVCbeltconveyor

  In order to help the belt conveyor user solve some related defects, such as the outer surface of the tail roller is smooth, the belt conveyor is not easy to slip when starting and heavy loading; the tail roller is round, no anti-belt The function of deviation, the service life of the bearing is short; Hongjiang technicians have absorbed advanced experience at home and abroad, and combined with years of work experience in the industry, the structure of the traditional tail wheel part has been comprehensively improved, and the belt conveyor has been designed. The wing-shaped tail wheel part.
    The wing-shaped tail wheel part of the PU belt conveyor is mainly composed of a wing-shaped drum, a shaft, a conical expansion sleeve, an outer spherical bearing with a slider seat, a bearing bracket, a tension adjusting screw and the like. Compared with the traditional tail wheel, the wing-shaped tail wheel has the following remarkable features:
    1. The PU PVC belt conveyor bearing and bearing housing are of integral structure. This structure is extremely convenient in installation, use and maintenance, occupies small installation space, and reduces the process of machining the bearing seat in the production process. The wing roller and the shaft are connected by a conical expansion sleeve; the bearing is a spherical bearing with a slider outer ball, which can slide on a standard shaft, and the bearing and the shaft are fixed by a set screw;

    2. The belt conveyor adopts the radial ball bearing with the outer ball of the slider. Compared with the ordinary bearing, it adopts the integral casting seat. The bearing has high manufacturing precision, good self-aligning performance, large load bearing capacity, especially the sealing performance is particularly good. The service life of the bearing is greatly prolonged; in the traditional tail wheel part, the sand dust easily enters the bearing from the gap between the bearing cover and the shaft, which seriously shortens the service life of the bearing.

    3. The belt conveyor tension adjustment mechanism consists of only one screw and four nuts. The two upper nuts of the bearing seat are locked for a long time. Loosen the nut on the inner side of the bearing bracket and tighten the nut on the outer side of the bearing bracket. The belt is tightened, and the belt is loosened. The traditional adjustment mechanism of the tail wheel is composed of the adjusting screw, the upper cover and the lower bottom plate. The upper cover needs to be bent and drilled. It is necessary to drill and tap the teeth after welding, and the connecting bolts that need to be placed on the lower bottom plate of the upper and lower bottom plates are easily loosened. Therefore, the tension adjustment mechanism of the wing-shaped tail wheel portion is simpler and more convenient than the tension adjustment mechanism of the conventional tail wheel portion in the composition, the manufacturing process, and the assembly and disassembly, and the use is more reliable.

    4. The surface friction coefficient of the belt conveyor wing roller is large, and the belt is not easy to slip when starting and heavy loading. The outer circumference of the airfoil drum is distributed in the circumferential direction, and the gap between the wings of the width of 35-40 mm is 40-45 mm. Therefore, during the operation of the belt conveyor, the friction coefficient between the belt and the drum is very large and it is not easy to slip.

    5. The belt conveyor wing roller has self-cleaning effect. The flaps on the outer surface of the drum are connected to the mother pipe seamless steel pipe through the web, and the webs are separated by a partition plate, and the partition plate forms an angle of three to five degrees with the seamless steel pipe. During the use of the belt conveyor, if there is material scattered, the material will slide along the partition, so as to avoid the material being pulled between the belt and the roller with the return belt, which damages the belt and damages the drum.

    6. The intermediate diameter of the belt conveyor's wing-shaped roller is 5~10mm larger than the diameter of the end, which has the function of preventing the belt from running off.

    7. Since the surface friction coefficient of the belt conveyor wing roller is large, the diameter of the drum is significantly smaller than that of the conventional tail roller. Taking the B1000 belt conveyor as an example, the diameter of the conventional smooth roller is generally 500m, and the diameter of the airfoil roller is generally 300m-350m, which greatly saves raw materials.

    8. Since the belt of the wing-shaped roller is not easy to slip on the drum, the belt damage caused by the material being pulled between the belt and the drum can be avoided, and the belt is prevented from being deflected, so the service life of the belt is greatly improved.
