In the first rectangular through hole, in this patent, the thin wire is positioned and limited by the fixed pulley set. However, since the fixed pulley set is installed in a fixed way, the required speed of pay-off and wire-pulling need to be consistent or change. It is not big. When the speed changes greatly, it is easy to loose the wire or cause the wire to break due to excessive tension. Although the thin wire after the broken wire is treated by setting a wire tightening plate in this patent, the speed has not been solved. When the change is too large, the problem of disconnection is caused.

It can be seen from the above solution that the setting of the load-bearing platform can adjust the tension of the wire between the first guide wheel group and the second guide wheel group by adding or reducing weights on it, so as to adjust The speed of the wire; the setting of the in-position sensor is used to detect the position of the load-bearing platform, so that when the second guide wheel group reaches the lower limit position, the in-position sensor sends a signal to the background, and the background system controls the drive The motor stops working, so that the coil is no longer out of the line, and the function of automatic start and stop is realized.

A preferred solution is that a mounting plate is provided on the top of the guide shaft, and the first guide wheel group is slidably fitted on the mounting plate through a support.

It can be seen from the above solution that the support is arranged in a sliding structure, so that the first guide wheel group can be displaced with the support, so as to adjust the direction of the wire and the tension of the wire.

A preferred solution is that the bottom of the wire storage mechanism is fixedly mounted on the frame, and the frame is fixedly connected to the top of the wire storage mechanism through at least one reinforcing plate.

It can be seen from the above solution that, through the arrangement of the reinforcing plate, the shaking of the wire storage mechanism during operation is reduced, and the stability of the equipment is ensured.

A preferred solution is that an electric box for power supply is provided on one side of the rack.
