When the material receiving rack 472 is full and the material receiving rack 472 needs to be replaced. The power mechanism decelerates to reduce the rotation speed of the material receiving tray 450. In the process of replacing the material receiving frame 472, the first vertical cylinder 441 starts to work, the piston rod 4411 moves upwards, and the first bearing seat 444 drives the pull rod to move upwards. Since the lower end of the pulling rod 443 is axially fixed to the lower end of the sliding sleeve 451 by the second nut 460, the sliding sleeve 451 moves upward. The four-bar linkage mechanism formed by the linkage rod 453, the supporting leg 452, the sliding sleeve 451 and the material collecting tray 450 is changed, the supporting leg 452 rotates around the hinged point of the supporting leg 452 and the material collecting tray 450 to be opened, and the steel wire is coiled after falling down from the material collecting tray 450

Specifically, the power of the transmission gear 445 comes from a gear driving mechanism, the gear driving mechanism is a gear motor reducer installed on the second installation part 411, the output end of the gear motor reducer is connected with a power output gear, and the power output gear is meshed with the transmission gear 445.

When the material receiving rack is replaced, the first vertical cylinder 441 starts to work, the piston rod 4411 moves downwards, and the first bearing seat 444 drives the pull rod to move downwards. Since the lower end of the pulling rod 443 is axially fixed to the lower end of the sliding sleeve 451 by the second nut 460, the sliding sleeve 451 moves downward along with it. The four-bar linkage mechanism formed by the linkage rod 453, the supporting leg 452, the sliding sleeve 451 and the material receiving tray 450 is changed, the supporting leg 452 rotates around the hinged point of the supporting leg and the material receiving tray 450 to be folded, the steel wire is coiled on the material receiving tray after falling through the material receiving tray 450, and the rotating speed is recovered at the moment.

The above description of the present invention is intended to be illustrative. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
