What is a conveyor chain?

The conveyor chain is the same as the transmission chain. The precision conveyor chain is also composed of a series of bearings, which are fixed by the chain plate with restraint, and the positional relationship between each other is very precise.

Conveyor chain introduction

Each bearing includes a pin and a sleeve on which the rollers of the chain rotate.Both the pin shaft and the sleeve undergo surface hardening treatment, which allows hinged joints under higher pressure, and can withstand the load pressure transmitted by the rollers and the impact during engagement.Conveyor chains of various strengths have a series of different chain pitches: the small chain pitch depends on the requirement of sufficient strength for the sprocket teeth, while the large chain pitch is usually determined by the rigidity of the chain plate and the general chain. If necessary, the sleeve between the chain plates can be strengthened to exceed the rated large chain pitch, but the gap for clearing the sleeve must be reserved in the gear teeth.

Introduction of conveyor chain

It is suitable for conveying all kinds of boxes, bags, pallets, etc., bulk materials, small items or irregular items need to be transported on pallets or in turnover boxes.It can transport a single piece of material with a large weight, or withstand a large impact load.

Structure: According to the driving mode, it can be divided into power roller line and unpowered roller line. According to the layout form, it can be divided into horizontal conveyor roller line, inclined conveyor roller line and turning roller line.It can also be specially designed according to customer requirements.

The inner width of the standard gauge drum line is 200, 300, 400, 500, 1200mm, etc. Other special specifications can also be adopted according to customer requirements. The standard turning radius of the turning drum line is 600, 900, 1200mm, etc., and other special specifications can also be adopted according to customer requirements. The diameters of the straight rollers are 38, 50, 60, 76, 89mm and so on.

特点

Conveyor belt equipment composition and characteristics with traction parts: Conveyor belts with traction parts generally include: traction parts, load-bearing members, driving devices, tensioning devices, redirecting devices and supports.The traction parts are used to transmit traction, which can be conveyor belts, traction chains or steel wire ropes; the load-bearing components are used to carry materials, including hoppers, brackets or spreaders, etc.; the driving device powers the conveyor, usually by electric motors, reducers and Brake (stop) and other components; the tensioning device generally has two types of screw type and heavy hammer type, which can maintain a certain tension and sag of the traction member to ensure the normal operation of the conveyor belt; the support member is used to support the traction member or load The components can be rollers, rollers, etc.The structural feature of the conveyor belt equipment with traction parts is: the material to be transported is installed in the carrying member connected with the traction part, or directly installed on the traction part (such as a conveyor belt), the traction part bypasses the head and tail of each roller or sprocket Connected to form a closed loop including a loaded branch for transporting materials and an unloaded branch for not transporting materials, and the continuous movement of the traction member is used to transport the materials.Composition and characteristics of conveyor belt equipment without traction parts: The structure of conveyor belt equipment without traction parts is different, and the working components used to transport materials are also different.Their structural characteristics are: use the rotating or reciprocating movement of the working member, or use the flow of the medium in the pipeline to transport the material forward.For example, the working component of a roller conveyor is a series of rollers, which rotates to transport materials; the working component of a screw conveyor is a spiral, which rotates in a trough to push materials along the trough; the work of a vibrating conveyor The component is a trough, which reciprocates to convey the materials placed in it.

Problem handling

Conveyor belt deviation is one of the common faults when the conveyor belt is running.There are many reasons for the deviation, the main reason is the low installation accuracy and poor daily maintenance.During the installation process, the head and tail rollers and the intermediate rollers should be on the same centerline as much as possible and parallel to each other to ensure that the conveyor belt is not deviated or less deviated.In addition, the strap joints should be correct, and the perimeters on both sides should be the same.In the course of use, if there is a deviation, the following checks must be made to determine the cause and make adjustments.The parts and treatment methods that are often checked for deviation of the conveyor belt are: (1) Check the misalignment between the horizontal centerline of the roller and the longitudinal centerline of the belt conveyor.If the non-coincidence value exceeds 3mm, the long mounting holes on both sides of the roller set should be used to adjust it.The specific method is which side of the conveyor belt is biased, which side of the roller group moves forward in the direction of the conveyor belt, or the other side moves backward. (2) Check the deviation value of the two planes of the bearing seat of the head and tail frame.If the deviation of the two planes is greater than 1mm, the two planes should be adjusted in the same plane.The adjustment method of the head roller is: if the conveyor belt deviates to the right side of the roller, the bearing seat on the right side of the roller should move forward or the left bearing seat should move backward; if the conveyor belt deviates to the left side of the roller, then The bearing seat on the left side of the drum should move forward or the bearing seat on the right side should move backward.The adjustment method of the tail roller is just the opposite of that of the head roller. (3) Check the position of the material on the conveyor belt.If the material is not centered on the cross section of the conveyor belt, it will cause the conveyor belt to deviate.If the material deviates to the right, the belt deviates to the left, and vice versa.When in use, the material should be centered as much as possible.In order to reduce or avoid the deviation of this kind of conveyor belt, a baffle plate can be added to change the direction and position of the material
