The above two steps need to be carried out on the cutting machine and the peeling machine respectively, and the same problem that the output power of the cylinder is difficult to adjust exists on the existing cutting machine and the peeling machine: the transmission mechanism in the cutting machine uses a cylinder to move the wire up and down. The two belts are clamped. After clamping, the motor drives the belt between the main and driven wheels to rotate. The friction between the belt and the wire drives the wire to move forward. However, due to the poor adjustability of the clamping force of the cylinder, some wires often Insufficient clamping force makes the belt and wire slip during the transmission process, making the transmission length shorter than the actual set cutting length; the same problem exists in the cutting part of the peeling machine.
