[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a wire drawing machine drum: it includes a drum body 1, an upper mounting seat 2 installed on the top of the drum body 1, a lower mounting seat 3 installed on the bottom of the drum body 1, a drive shaft 19 connected to the bottom of the drum body 1, the drive shaft 19 passing through the lower mounting seat 3 and connected to the power system of the wire drawing machine, mounting grooves 4 for mounting the drum body 1 are provided on the upper mounting seat 2 and the lower mounting seat 3, the upper and lower ends of the drum body 1 are rotatably connected to the mounting grooves 4 of the upper mounting seat 2 and the lower mounting seat 3 through bearings, a pressure roller mechanism 5 is installed on one side of the drum body 1, the pressure roller mechanism 5 includes a rubber pressure roller 6 and a connecting bracket 7, the rubber pressure roller 6 is detachably mounted on one side of the upper mounting seat 2 and the lower mounting seat 3 through the connecting bracket 7, and a connecting mechanism is provided between the connecting bracket 7 and the upper mounting seat 2 and the lower mounting seat 3.

[0022] Furthermore, the connecting bracket 7 is provided with a pressure roller adjustment mechanism, which includes a bearing seat 8, a movable slide groove 9 and an adjusting wheel 10. The two ends of the rubber pressure roller 6 are fixedly installed with rotating shafts 11, which are installed in the bearing seat 8 through bearings, and the bearing seat 8 is slidably installed in the movable slide groove 9.

[0023] In this embodiment, by rotating the adjusting wheel 10, the bearing seat 8 can be driven to slide in the movable groove 9, thereby adjusting the distance between the rubber pressure roller 6 and the drum body 1, and realizing the pressure adjustment of the wire during the wire drawing process.

[0024] Furthermore, an adjusting rod 12 is connected to the adjusting wheel 10. The adjusting rod 12 is installed at one end of the connecting bracket 7 and is threadedly connected to the connecting bracket 7. The other end of the adjusting rod 12 is connected to a pressure plate 13, which is located on one side of the bearing seat 8.

[0025] In this embodiment, by rotating the adjusting rod 12, the pressure plate 13 can be driven to apply pressure to the bearing seat 8. Since the adjusting rod 12 is threadedly connected to the connecting bracket 7, rotating the adjusting rod 12 can achieve linear movement of the pressure plate 13 on the connecting bracket 7. This design generates pressure between the rubber pressure roller 6 and the drum body 1, thereby preventing the resistance alloy wire from slipping on the drum.

[0026] Furthermore, a return spring 14 is installed inside the movable slide 9, and the return spring 14 is located on one side of the bearing seat 8.

[0027] In this embodiment, one end of the return spring 14 is fixedly connected to the inner wall of the movable slide groove 9, and the other end is in contact with the side of the bearing seat 8. When it is necessary to adjust the position of the rubber pressure roller 6, the elastic force of the return spring 14 can be overcome by rotating the adjusting wheel 10, so that the bearing seat 8 slides in the movable slide groove 9.

[0028] Furthermore, the connecting mechanism includes at least one set of assembly sliders 15, which are fixedly installed on the surfaces of the upper mounting base 2 and the lower mounting base 3, and the assembly sliders 15 are arranged in a circular pattern.

[0029] In this embodiment, the assembly slider 15 enhances the stability and firmness of the connection between the upper mounting base 2 and the lower mounting base 3. The circularly distributed assembly sliders 15 can adjust the contact position between the rubber pressure roller 6 and the drum body 1 as needed.

[0030] Furthermore, the connecting bracket 7 is provided with a mating groove 16 that cooperates with the assembly slider 15, and the connecting bracket 7 is inserted into the assembly slider 15 through the mating groove 16.

[0031] In this embodiment, when it is necessary to adjust the position of the rubber roller 6 or perform maintenance, the relevant operations can be completed simply by removing the connecting bracket 7 from the assembly slider 15, which greatly improves work efficiency.

[0032] Furthermore, a locking nut 17 is installed on the outside of the mating groove 16 of the connecting bracket 7, and the locking nut 17 is threadedly connected to the connecting bracket 7.

[0033] In this embodiment, the locking nut 17 further secures the connection between the connecting bracket 7 and the assembly slider 15, preventing the connecting bracket 7 from loosening or falling off during use. By rotating the locking nut 17, its tightness can be adjusted to ensure that the connecting bracket 7 is securely installed on the assembly slider 15, thereby improving the stability and reliability of the entire device.

[0034] Furthermore, the rubber roller 6 is provided with a plurality of semi-circular arc-shaped extrusion grooves 18.

[0035] In this embodiment, the semi-circular extrusion groove 18 can more effectively extrude the wire, thereby preventing the resistance alloy wire from slipping on the drum.

[0036] Working Principle: In use, the pressure roller mechanism 5 is first installed on one side of the drum body 1. During the wire drawing process, the drive shaft drives the drum body 1 to rotate, and the resistance alloy wire is pulled on the drum body 1. At the same time, the contact force between the rubber pressure roller 6 and the drum body 1 can be adjusted. The semi-circular extrusion groove 18 on the rubber pressure roller 6 can more effectively extrude the wire and prevent the resistance alloy wire from slipping on the drum. In addition, when it is necessary to adjust the position of the rubber pressure roller 6 or perform maintenance, the relevant operations can be completed simply by removing the connecting bracket 7 from the assembly slider 15, which greatly improves work efficiency. This utility model has a simple structure and is easy to operate, and has high practical value and promotion value.
