Its main features are: the soft steel wire 31 is connected to the swing rod 25 and the brake pads 33, 35. Before the machine is operated, the tension spring 26 generates tension to pull the swing rod 23, and the swing rod 25 is pried through the principle of leverage to pull the soft steel wire 31. Next, hold the brake and hold the brake seat for 30 degrees without turning.

The present invention solves the problems of the prior art. In addition to the original threading holes, rotating shafts, bases, struts, and bearings, the present invention adds guide wheels, springs, and Y-shaped lever mechanisms (hereinafter referred to as swing bars) ) and controllable and flexible brake pads (driven by soft steel wires) and other main components. Without pulling the female copper wire, the brake pad under the turntable is tightened by the soft steel wire connected to it, and the brake will not rotate, so that ① it will not move around at will when there is no production, and ② it will not stop due to shutdown when the machine is stopped. The resulting inertia produces chaotic lines. When in use, the female copper wire is pulled by the wire drawing machine, passes through the threading hole, and passes through two guide wheels. Due to the leverage, one of the guide wheels has a force of upward pull, and the other guide wheel has a force of pull down. The force of pulling down loosens the tightened soft steel wire by prying the swing bar, and the brake pads are released. The faster the pay-off speed of the mother copper wire, the greater the release degree of the brake pads, and the more free and flexible the pay-off device can rotate, so that the degree of freedom of the rotor of the pay-off device can be automatically adjusted through the tension of the pay-off mother copper wire to prevent the release of the wire. Blocking, effectively prevent the occurrence of thread injury and disconnection.

As an optimization, the two new guide wheels, the Y-shaped fork and the fork bearing of the pay-off device form a lever. With such a design, on the one hand, the design of the two guide wheels increases the pulling angle of the busbar in the threading hole, which can reduce the friction of the busbar on the threading hole.

As an optimization, the force formed by the lever acts on the soft steel wire, and the soft steel wire pulls the brake pad on the turntable to control the degree of freedom of the bearing on the turntable and prevent the wire from being blocked;

As an optimization, the brake is connected with a short soft steel wire, and the release degree of the brake is controlled by the soft steel wire. Before the soft steel wire is connected to the brake pad, pass through the small circular wire inlet hole. This design is conducive to the uniform force of the soft steel wire and is not easy to break;

As an optimization, the length of the struts can be adjusted according to different reels without replacing the entire pay-off rotor.

After using the above technical solution, in the process of using the pay-off device, regardless of the pay-off speed and the pay-off tension of the mother copper wire, the steel wire can be adjusted by leverage to adjust the degree of brake release, so that the pay-off rotor is free. Flexible rotation, effective control of wounded and broken threads.

The specific implementation methods listed above are non-limiting, and for those skilled in the art, various improvements and changes made without departing from the scope of the present invention belong to the protection scope of the present invention.
