[0002] Belt conveyors have the characteristics of simple structure, large conveying capacity, wide range of conveying materials, long transportation distance, convenient loading and unloading, high reliability, low freight and high degree of automation. The belt is bonded together with the head and tail sections to form a stable circulation structure. The key step in the early stage of belt bonding is to peel off the bonding area, that is, to peel the head and tail sections of the belt into a stepped multi-layer structure, so that the bonding surfaces of the head and tail overlap and increase the bonding surface.

[0003] The utility model with application number CN201320647031.7 discloses a special device for tearing off the belt of a belt conveyor. The belt is clamped by a quick clip, and the motor generates power to drive the reducer and the rolling rotation, pull the traction rope, and then drive the quick clip to tear the belt.

[0004] The above device tears the belt by pulling the quick clip through the motor. The quick clip and the belt are easy to fall off and the fixation is unstable. The quick clip is small and the belt is wide. When tearing the belt, the upper and lower layers of the belt are easy to skew. The belt needs to be transported to the device manually. The device is inconvenient to move. When the motor is damaged, manual operation is required, the labor intensity is high and the work efficiency is low.
