[0002] Belt conveyors are important transportation equipment in coal mines, undertaking the task of transporting underground coal blocks to the ground. Steel wire conveyor belts are also the most widely used type in coal mine conveyors, with characteristics such as high tensile strength and strong tear resistance. Since the production manufacturers of rubber belts are of fixed length, during actual use, vulcanization splicing is carried out according to requirements to make it into a closed circle. The splicing requirements of the conveyor belt need to strip the steel wires at each joint, place the steel wires crosswise, then cover the rubber bottom and surface, and finally complete the butt joint of the steel wire belt through hot melt vulcanization treatment. Currently, there are two widely used wire stripping methods. One is manual cutting with a blade by hand, and the other is cutting with mechanical equipment and completing it by the traction of an electric motor. The existing methods have the following disadvantages:

[0003] Since the strength of steel wire conveyor belts is generally very high, the belt thickness is greater than 25 mm, and the hardness is greater than 70 hd. Relying on manual cutting by hand is very labor-intensive. And when cutting manually, impurities such as hand sweat will contaminate the cut surface, resulting in poor vulcanization effect in the later stage; when the tool gets stuck, there is also a risk of the steel wire breaking and hurting people during traction.
