[0023] A wire pay-off drum 11 is disposed at the bottom of the frame 1 .
[0024] The guide wheel 2 is arranged on the top of the frame 1 .
[0025] The sensing device 3 is located below the guide wheel 2, and includes a connecting plate 31, a movable plate 32, two light sensors 33, two sensing columns 34 and two first rollers 35. The movable plate 32 is a triangular structure. The upper end of the movable plate 32 is movably arranged on the connecting plate 31 through a pin shaft 321. The two first rollers 35 are arranged in parallel on the front of the movable plate 31. There is a line entry space 351 between the two first rollers 35. One side of the line entry edge 21 of the guide wheel 2 is located on the same straight line as the line entry space 351. The wire core 111 on the pay-off reel 11 passes through the line entry space 351 and is then wound around the wire core 111. The two sensing columns 34 are arranged on the back of the movable plate 32, and correspond to the positions of the two first rollers 35 one by one; the two light sensors 33 are arranged in parallel at the lower end of the connecting plate 31, and are respectively located on both sides of the two sensing columns 34; an L-shaped fixing plate 36 is also fixed to the lower end of the connecting plate 31, and two second rollers 361 are horizontally arranged on the L-shaped fixing plate 36, and the second rollers 361 are located below the first rollers 35 and are in a vertical state with the first rollers 35. By arranging the two second rollers 361, the line core 111 can be prevented from moving forward and backward, and the line core 111 can be controlled on the guide wheel 2.
[0026] The linear slide module 4 is fixedly set on the top of the frame 1, and the guide wheel 2 and the sensor device 3 are fixedly connected to the linear slide module 4. The linear slide module 4 includes a base 41, a drive motor 42, a screw rod 43 and a slider 44. The base 41 is fixed to the top of the frame 1 through two brackets 411. The drive motor 42 is set on the left side of the base 41, and the screw rod 43 is mounted on the right side of the base 41, and one end of the screw rod 43 is connected to the output end of the drive motor 42.
