The motor control box starts the traction motor, and drives the traction frame to move on the tooth groove through the traction motor. The lower pulley and the pressure wheel together constitute a clamping conveying mechanism, which can smoothly convey the cable. The cable fixing clamp stretches the cable to the required length. Finally, the cable is cut by the shear knife in the shearing machine box.
