- Reasons for longitudinal tearing of the car assembly linel:
(1) Vibration and impact caused by loosening and falling of fasteners cause coal liners, guide plates, etc. to fall.
(2) Foreign matter is mixed in the material, the foreign matter is hard, has edges and corners, and the coal pipe is blocked and squeezed.
(3) Defects of the supporting roller, causing scratches on the supporting roller frame.
(4) After a serious deviation, the conveyor belt is suspended by the frame.
(5) The cleaning agent is caught in the drum (returning the cleaning agent), the bolts are loose, and there is a bounce warning.
Second, the conveyor assembly line company introduces you, the reason for the cracking of the conveyor belt:
(1) Due to space limitations, the conveyor belt has many bending times.
(2) Combined vulcanization for more than two times due to various reasons.
- Reasons for the tearing of the vulcanized joint of the conveyor belt:
(1) The diameter of the reversing drum is small, and the bending stress of the conveyor belt is large.
(2) The quality of the vulcanized joints of the conveyor belt is poor, especially if vulcanized more than twice, the joint strength is significantly reduced, or the canvas layer is cut when the glue is connected, or the strength is reduced due to grinding leakage. .
(3) For the reversible conveyor, since the upper and lower overlap can only be carried out in one direction, it is easy to be scratched by the cleaner on the sharp corners of the belt, unloader and other equipment.
Four. Reasons for damage to the adhesive surface covered by the conveyor belt:
(1) The gap between the guide groove liner and the tape is improper, resulting in abnormal wear or foreign objects embedded in the gap, resulting in abnormal wear or scratches.
(2) The flow rate of the material at the guide groove is inconsistent with the speed of the conveyor belt, the drop is large, and the accelerated rubber surface wears.
(3) The roller is damaged, causing abnormal wear or scraping of the belt.
(4) Illegal operation, welding slag fouling during maintenance, scratching with cleaning agent, etc.
(5) The slippage of the tape will also cause abnormal wear of the tape.
In the process of using conveyor belts, the most common problems are: foreign matter scratches, local foreign matter damage, wear, perforation, etc.
Generally, due to local damage caused by foreign matter, the conveyor belt should be completely dismantled according to the traditional method, repaired and heated to vulcanize or scrapped for replacement.
