Description

Technical Field

[0002] Rollers are important parts of belt conveyors. There are many types and large quantities of rollers, which can support the weight of conveyor belts and materials. They account for 35% of the total cost of a belt conveyor and produce more than 70% of the resistance, so the quality of rollers is particularly important. There are two types of rollers: steel and plastic.

[0003] The function of the roller is to support the weight of the conveyor belt and the material. The roller must operate flexibly and reliably. Reducing the friction between the conveyor belt and the roller plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller is a relatively small component in the belt conveyor and its structure is not complicated, it is not easy to manufacture high-quality rollers.

[0004] When the roller conveyor is used to transport goods loaded on pallets, when a manual hydraulic forklift pushes the pallet to the conveying end of the roller conveyor, it often causes inconvenience in actual use because the conveyor often does not have a self-adjustment function for its length.

At the same time, the elastic member 40 is stretched, and the control roller 39 slides along the chute 4 35. The distance between the control roller 39 and the auxiliary rollers 1 36 and 2 37 is shortened, and the driving device connected to the control roller 39 is started. The operation of the driving device will drive the conveying belt 41 to operate, thereby realizing the conveying operation of the conveyor;
