Please refer to FIG. 1 and FIG. 2, an embodiment of the present utility model provides a wire pay-off frame with protection and alarm functions, including a mounting frame 1, a guide roller 2 for wire guide, a lifting guide rod 3, and a movable lifting plate 4. Components such as the spring 5 and the first sensor 6 for detecting whether the movable lifting plate 4 is displaced. The structure and working principle of each component will be described below.

The guide roller 2 is horizontally and rotatably installed on the installation frame 1 through the roller shaft 21, and the lift guide rod 3 is longitudinally arranged at the bottom of the installation frame 1. The plate 4 can be mounted on the lifting guide rod 3 so as to be up and down through the linear bearing 41. The movable lifting plate 4 is provided with a first threading hollow shaft 42 for the wire to pass through. The second threading hollow shaft 43 directly above the first threading hollow shaft 42, the springs 5 are respectively sleeved outside the corresponding lifting guide rods 3 and located between the movable lifting plate 4 and the bottom of the mounting frame 1, the first sensor 6 is installed by The plate 61 is mounted on the mounting frame 1 and is located on the side of the movable lifting plate 4 . Among them, the diameter of the guide roller 2 can be gradually reduced from both ends to the middle part, so as to form a groove, so that the wire can always pass through the middle position of the guide roller 2, which improves the running stability of the pay-off frame.

Preferably, the first sensor 6 may be a common proximity switch or other photoelectric sensor in the market, which is not limited to this embodiment.

As shown in FIG. 1 , in a specific implementation, the mounting frame 1 can be installed on the top end of the support frame 7 . The support frame 7 includes a corner swing arm 71 , a fixed support arm 72 and a driving cylinder 73 , and the bottom end of the corner swing arm 71 is connected to the fixed support arm 71 The top end of the support arm 72 is rotatably connected, the driving cylinder 73 is rotatably mounted on the fixed support arm 72 through the adapter seat 74, the output shaft of the driving cylinder 73 is rotatably connected with the corner swing arm 71, and the mounting frame 1 passes through the triangular guide provided on the top. The wheel carrier 11 is mounted on the tip end of the corner swing arm 71 .
