The bottom of the tensioning roller 77 is higher than the top of the conveying roller 711 in the initial state, and the number of the tensioning rollers 77 is set to thirteen groups. The thirteen groups of tensioning rollers 77 can be In order to keep the wires in transportation in a tensioned state and prevent them from being entangled, the front end of the rotating shaft 79 is fixedly connected to the output shaft of the motor 78, the surface of the rotating shaft 79 is fixedly connected to a driving gear 710, and the surface of the conveying roller 711 is fixedly connected to a driven gear 712 and a separating wheel 713.
