Cause:  the conveyor belt is overloaded or jammed on the surface; Lubrication problem of conveyor belt system; There is a problem with the heat sink.

Measures:  regularly check and clean the residues on the surface of the conveyor belt to reduce the load of the conveyor belt; Regularly check the operation condition of all transmission parts and add lubricating oil in time; Check the heat sink and clean the dust on the surface of the ventilation mesh in time.

Cause: the conveyor belt deviates from the position, resulting in friction and tear with the edge; It is related to the material of the transported materials; The conveyor belt has not been replaced for a long time and has aging problems.

Measures: regularly check the conveyor belt and replace it in time; Select the conveyor belt material matching with the material; Check whether the belt is in the center before operation.

Cause: the load of the conveyor belt is too large, but the tension is insufficient; Rain reduces belt friction.

Measures: detect the speed change of conveyor belt before operation; Reduce the load of the conveyor belt and check and adjust its tension; Avoid rain contact.

Cause: excessive load; Belt offset.

Measures: check the conveyor  belt status before operation, adjust the conveyor belt position and reduce the load of the belt in time.
