Buffer device of belt conveyor carrier roller

Abstract

The invention discloses a buffer device of a belt conveyor carrier roller. The buffer device comprises a plurality of carrier roller bodies, a carrier roller shaft, bearing pedestals, a bearing, a sealing layer, an oil sealing device, two support frames and buffer device bodies, wherein the two support frames are arranged on the left and right parts; the carrier roller bodies are connected betweenthe two support frames; the bearing pedestals are arranged on the two sides of the carrier roller bodies; the bearing, the sealing layer and the oil sealing device are mounted in the bearing pedestals; the sealing layer wraps and covers the bearing and the oil sealing device; the carrier roller shaft penetrates through the middle of each of the carrier roller bodies and is connected with the bearing pedestals; the buffer device bodies are mounted at the two ends of the carrier roller shaft; each of the buffer device bodies comprises a sliding stop dog, a spring piece and a buckle piece; the sliding stop dog is connected with one end of the carrier roller shaft; and the spring piece is connected with the sliding stop dog and the buckle piece. The buffer device has the benefit of effectively buffering downward impact force received by the belt to prevent the belt from inclining.

Description

technical field [0001] The invention relates to the technical field of conveyor components, in particular to a buffer device for idler rollers of belt conveyors. Background technique [0002] The belt conveyor is a continuous transport machine with a conveyor belt as the traction and carrying parts. The conveyor belt winds around the drive roller and various redirecting rollers, and the tension device gives proper tension. When working, driven by the drive device, the friction and tension between the roller and the conveyor belt make the Conveyor belt running. The material is continuously sent to the conveyor belt, and moves together with the conveyor belt, so as to realize the conveying of the material. [0003] The main components of the belt conveyor include racks, idlers, rollers, driving devices, tensioning devices and belts. There are rollers at both ends of the metal frame, and there are multiple sets of rollers on the upper and lower sides of the frame. The belts ...

AI Technical Summary

Problems solved by technology

[0004] Because the sealing effect of the traditional idler is poor, it is easy to be filled and blocked by debris, causing the idler to rust and cannot rotate normally.

In addition, because the bearings in the idler rollers need to be lubricated regularly, which is laborious and time-consuming, it is difficult to implement on-site operations, so the general idler rollers are seldom oiled, which results in a short service life of the idler rollers. And the replacement is frequent, which increases the labor load of maintenance personnel

In addition, during the daily use of the belt conveyor, a problem is often encountered: the bearing on the half shaft of the idler is damaged, and the support height at one end of the idler drops, causing the conveyor belt to tilt and deviate, thus tearing the conveyor belt

[0005] In addition, when the belt conveyor is transporting heavy items, the traditional rigid rollers cannot absorb the strong impact force when the raw materials fall, and it is easy to damage the rollers, causing the belt to tear longitudinally, which not only causes great damage to the machine Large damage also affects work progress
