[0023] The support leg 2 stably supports the workbench 1 on a work plane such as the ground, bears the weight of the entire device and components such as the winding roller 7 and the wire being drawn, evenly disperses these weights through reasonable structural design, prevents the workbench 1 from shaking or tilting due to uneven force, and creates good conditions for precise and stable wire drawing and winding work. The fixing plate 3 is fixed to the workbench 1 to provide a stable mounting base for the first motor 4. The output end of the first motor 4 (a servo motor that can accurately control rotation) is connected to the turntable 5 through the fixing plate 3. When the first motor 4 is started, the motor drives the turntable 5 to move at a constant speed in a circular motion. Since the winding roller 7 is stably installed on the turntable 5 through a fixing member, the winding roller 7 will rotate synchronously with the turntable 5, thereby achieving winding of the wire drawn from the wire drawing die. Moreover, because a servo motor is used, the speed and direction of the turntable 5 and the winding roller 7 can be accurately controlled, and the winding speed can be accurately controlled according to actual production needs, ensuring a smooth and constant winding process and enabling the wire to be uniformly and tightly wound on the winding roller 7, thereby improving winding quality. The workbench 1 is provided with a first sliding groove, and the first sliding groove is provided with a first screw rod 8. The output end of the second motor 9 (also a servo motor for easy and accurate control) is connected to the first screw rod 8. The moving plate 10 extends into the first sliding groove below and is threadedly connected to the first screw rod 8. The moving plate 10 is provided with a bearing disc 11 for bearing the winding roller 7. When it is necessary to adapt to winding rollers 7 of different specifications or to adjust the support position of the winding roller 7, the second motor 9 is started, the motor drives the first screw rod 8 to rotate, and according to the screw transmission principle, the moving plate 10 moves linearly in the first sliding groove, thereby moving the bearing disc 11 to the appropriate position to better support the winding roller 7, avoiding shaking or deviation of the winding roller 7 during rotation due to unstable support, and ensuring smooth and stable winding work.

[0024] The fixing member comprises a reversible screw 12, a handle 13 and a clamping plate 14, the clamping plate 14 is in U shape, the rotating disc 5 is further provided with a movable slot near one end of the supporting block 6, the reversible screw 12 and two sets of symmetrically arranged clamping plates 14 are arranged in the movable slot, one side of the clamping plate 14 is threadedly connected with the reversible screw 12, the inner wall of the winding roller 7 is further provided with a clamping groove for clamping the other end of the clamping plate 14, the reversible screw 12 penetrates through the rotating disc 5 and is connected with the handle 13, the supporting block 6 is further provided with a receiving groove matched with the clamping plate 14, when the winding roller 7 is installed, the winding roller 7 is sleeved on the supporting block 6, the supporting block 6 is provided with the receiving groove matched with the clamping plate 14. Then the handle 13 is rotated to drive the reversible screw 12 to rotate, based on the thread transmission characteristics of the reversible screw 12, the two sets of symmetrically arranged clamping plates 14 will move towards each other, one end of the clamping plate 14 will be clamped into the clamping groove in the inner wall of the winding roller 7, and the other end will be received into the receiving groove in the supporting block 6, so that the winding roller 7 is firmly fixed on the rotating disc 5, and the loosening phenomenon of the winding roller 7 in the subsequent rotating and winding process is effectively prevented.

[0025] In actual use, the wire assembly includes a sliding frame 15, a second screw rod 16, a third motor 17, a guide frame 18, an elastic element 19, a guide seat 20 and a guide roller 21. The sliding frame 15 is fixed on the workbench 1, and a second sliding groove with an upper opening is arranged on the sliding frame 15. The second screw rod 16 is arranged in the sliding frame 15. The output end of the third motor 17 penetrates through the sliding frame 15 and is connected with the second screw rod 16. The guide frame 18 extends into the second sliding groove below and is threadedly connected with the second screw rod 16. The elastic element 19 is arranged below the inner top wall of the guide frame 18. The guide seat 20 is arranged below the elastic element 19. The guide roller 21 is arranged below the guide seat 20. The output end of the third motor 17 (a servo motor) penetrates through the sliding frame 15 and is connected with the second screw rod 16. The guide frame 18 extends into the second sliding groove below and is threadedly connected with the second screw rod 16. In the process of wire drawing and winding, the third motor 17 is started. The motor drives the second screw rod 16 to rotate. Based on the screw transmission principle, the guide frame 18 moves linearly in the second sliding groove (if the second screw rod 16 rotates forward, the guide frame 18 moves in one direction; if it rotates reversely, it moves in the opposite direction). The operator can flexibly adjust the horizontal position of the guide frame 18 by controlling the third motor 17 according to the actual position of the winding roller 7 and the wire drawing condition, so as to ensure that the guide roller 21 below the guide frame 18 can accurately guide the drawn wire to the appropriate position on the winding roller 7, so as to ensure that the wire can be uniformly wound on the winding roller 7, avoid the uneven winding of the wire (such as local accumulation and deviation), improve the winding quality, and the elastic element 19 (such as a spring or other elastic element) is arranged below the inner top wall of the guide frame 18. The guide seat 20 is connected below the elastic element 19. The guide roller 21 is installed below the guide seat 20. When the tension of the wire fluctuates (for example, due to changes in the drawing speed or the gradual increase in the diameter of the winding roller 7), the elastic element 19 can be vertically self-adaptively stretched and contracted to drive the guide seat 20 and the guide roller 21 to move up and down, so that the guide roller 21 always maintains good contact with the wire, and the wire is continuously and stably guided. The guide roller 21 is symmetrically provided with side plates 22 on the left and right sides. The side plates 22 symmetrically arranged on the left and right sides of the guide roller 21 limit the wire, so that the wire can only move in the predetermined forward and backward direction on the guide roller 21, preventing the wire from sliding left and right on the guide roller 21, further ensuring that the wire is accurately guided to the winding roller 7 in the predetermined direction, and enhancing the accuracy of the wire and the uniformity of the winding.
