The internal cavity is symmetrically provided with first transmission screws 4 at the top and bottom. The two ends of the first transmission screws 4 are rotatably connected to the take-up auxiliary shaft 33. Each first transmission screw 4 has a first limiting shaft 43 on its left and right sides. The upper first transmission screw 4 has a first screw motor 41 on one end. The surfaces of the two first transmission screws 4 are fitted with meshing gears 42 that are hinged to each other. The surfaces of the two first transmission screws 4 are fitted with magnetic levitation frames 44. The first limiting shafts 43 slide through the corresponding magnetic levitation frames 44. A magnetic levitation threading block 45 is provided between the two magnetic levitation frames 44. The magnetic levitation threading block 45 is provided with slots on both sides of the take-up auxiliary shaft 33.

[0018] The back of the moving frame 23 is transversely screw-plugged with a second transmission screw rod 21, the top and bottom of the second transmission screw rod 21 are provided with second limiting shafts 22, the two second limiting shafts 22 are slidably arranged with the moving frame 23, the two ends of the second limiting shaft 22 are fixed in the inner cavity of the main body box 1, and the two ends of the second transmission screw rod 21 are connected with a second screw rod motor 2.

[0019] The four sides of the connection between the wire collecting auxiliary shaft 33 and the connecting plate 3 are provided with reinforcing ribs 35, the top of the outer side of the moving frame 23 is provided with an infrared transmitter 32, the top of the end of the wire collecting auxiliary shaft 33 away from the connecting plate 3 is provided with an infrared receiver 34 corresponding to the infrared transmitter 32, and the infrared transmitter 32 and the infrared receiver 34 play a calibration effect, when misalignment occurs, the bottom of the connecting plate 3 is pushed forward by the rear air cylinder 31 to realize the calibration of the wire collecting auxiliary shaft 33.
