[0022] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0023] Reference Figure 1 to Figure 2 As shown, a pay-off rack that prevents wire jumping and automatically stops in an emergency is provided, including a pay-off rack 1, a rotatable limit ring 2 is provided on the pay-off rack 1, a copper rod 4 is provided in the limit ring 2, a limit switch 3 is fixedly installed on the pay-off rack 1, the limit switch 3 is connected to the limit ring 2 through a limit paddle 5, and the limit switch 3 is electrically connected to the emergency stop device.

[0024] In this embodiment, during the wire-laying process, the copper rod 4 is passed through the limit ring 2, and then the limit ring 2 is pressed down until it contacts the surface of the copper rod 4. When the copper rod 4 is knotted, the knot drives the limit ring 2 to rotate, thereby causing the limit paddle 5 to shift. The shift of the limit paddle 5 triggers the activation of the limit switch 3. The limit switch 3 is connected to the emergency stop device, thereby starting the emergency stop device and automatically stopping the machine to ensure the safety of equipment and personnel and prevent the copper rod 4 from jumping out.

[0025] In one embodiment of the present invention, a through hole is provided on the pay-off frame 1 for the copper rod 4 to pass through, and a wire inlet 11 and a wire outlet 12 are respectively provided at both ends of the through hole. A bearing ring 13 is welded on the wire inlet 11, and the bearing ring 13 is used to prevent the copper rod 4 from jumping out during the normal wire paying process to ensure the safety of the equipment and operators. The limit ring 2 is rotatably arranged on one side of the wire outlet 12, and the bearing ring 13 also protects the wire inlet 11 from being damaged.

[0026] Furthermore, the diameter of the wire inlet 11 is smaller than the diameter of the wire outlet 12. The small size of the wire inlet 11 is for better wire winding, and the large size of the wire outlet 12 is because the equipment pays out the wire too fast. In order to prevent the copper rod 4 from damaging the through hole, the wire outlet 12 is designed to have a large diameter, so that the copper rod 4 is not easy to rub against the inner wall of the through hole during the rapid pay-off process, thereby preventing the copper rod 4 and the through hole from being damaged.

[0027] In one embodiment of the present invention, a mounting base 14 is fixedly mounted on the pay-off frame 1, and the limit switch 3 is fixedly mounted on the mounting base 14. Preferably, the mounting base 14 is arranged at the bottom of the pay-off frame 1, which is conducive to connecting the limit switch 3 with the limit ring 2 using a wire, facilitating the wire winding connection, and avoiding the wire affecting the pay-off of the copper rod 4. The mounting base 14 is welded and fixed to the pay-off frame 1.

[0028] In one embodiment of the present invention, a rotating rod 21 is welded to the limit ring 2, and a hollow cylinder 15 is symmetrically arranged on one side of the wire pay-off frame 1. Both ends of the rotating rod 21 are respectively installed in the hollow cylinder 15 so that the limit ring 2 can move up and down. Inserting the rotating rod 21 into the hollow cylinder 15 can make the limit ring 2 rotate up and down. When the copper rod 4 passes through the limit ring 2, the limit ring 2 rotates downward and is in a falling state, contacting the surface of the copper rod 4. At this time, the limit switch 3 will not be triggered and the emergency stop will not be activated; when the copper rod 4 is brought up due to knotting, it touches the limit ring 2 to activate the limit switch 3. At this time, the emergency stop device is also activated to avoid damage to the equipment due to severe knotting and pulling it into the equipment, and at the same time, it can also avoid accidental injury to the operator.

[0029] Furthermore, the rotating rod 21 is fixedly connected to the limit paddle 5, and the two parts are fixedly connected by bolts or welding. The limit paddle 5 is rotatably connected to the limit switch 3, and the limit paddle 5 is fixed on the limit ring 2. When the limit ring 2 is rotated by external force, the limit paddle 5 rotates to a certain angle to trigger the limit switch 3, and the equipment immediately stops to ensure the safety of the equipment and the operator.

[0030] In one embodiment of the present invention, the emergency stop device is installed on the pay-off frame 1.

[0031] In one embodiment of the present invention, in order to protect the through hole from being damaged, a soft material such as rubber, silicone, plastic, sponge, foam, etc. is provided in the through hole to prevent the copper rod 4 from rubbing against the through hole during normal wire laying, causing damage to both.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
