Description

Technical Field

[0001] This utility model relates to the field of enameled wire tension adjustment, specifically to a tension adjustment device for automatic winding of enameled wire. Background Technology

[0002] Enameled wire consists of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. It is mainly used for winding electromagnetic coils. Copper alloy enameled wire is a type of enameled wire, possessing good electrical and thermal conductivity.

[0003] In existing technology, to facilitate the winding of enameled wire, a tension regulating device is used to tighten the enameled wire to prevent it from becoming loose during winding and affecting subsequent use. However, the tensioning device can generally only stretch the enameled wire to a fixed tension for conveying. During the production and conveying process of enameled wire, the position of the enameled wire will constantly change when it is wound onto the reel. When the enameled wire is under a fixed tension, it will repeatedly be in a state of slack and over-tightening. Uneven tension on the enameled wire can lead to breakage and affect production quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0016] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-7 According to an embodiment of the present invention, an automatic tension adjustment device for winding enameled wire includes a workbench 1, a mounting frame 2 is provided on the side of the workbench 1, a through hole is provided on the side of the mounting frame 2, a first bearing 3 is provided in the through hole, a take-up roller 4 is inserted into the first bearing 3, a base plate 5 is provided on the side of the mounting frame 2, a drive motor 6 is provided on the surface of the base plate 5, and a threaded groove 7 is provided on the surface of the workbench 1, a guide rod 8 is screwed into the threaded groove 7. When the enameled wire is tensioned, the drive motor 6 can be started to drive the take-up roller 4 to rotate in conjunction with the first bearing 3, thereby automatically winding the enameled wire and improving the winding speed of the enameled wire.

[0017] A lifting plate 9 is fitted onto the surface of the guide rod 8. A support rod 10 is provided on the side of the lifting plate 9. A second bearing 11 is fitted onto the surface of the support rod 10. A tension tube 12 is fitted onto the outer ring surface of the second bearing 11. A positioning ring 13 is fitted onto the surface of the guide rod 8. A tension spring 14 is provided onto the surface of the positioning ring 13. The inner ring surface of the second bearing 11 is fixedly connected to the surface of the support rod 10. The second bearing 11 facilitates the rotation of the tension tube 12 and reduces the friction of the tension tube 12 on the enameled wire.

[0018] The workbench 1 is provided with a mounting plate 15, and a positioning bearing 16 is provided on the surface of the mounting plate 15. A movable screw 17 is inserted into the positioning bearing 16, and a support plate 18 is screwed onto the surface of the movable screw 17. The movable screw 17 can be rotated by cooperating with the positioning bearing 16. The support plate 18 is screwed onto the movable screw 17, so that the height of the support plate 18 can be adjusted by rotating the movable screw 17.

[0019] Please refer to the figure. Figure 1 , Figure 2 and Figure 6 As shown, the mounting bracket 2 is fixedly connected to the side of the workbench 1, the take-up roller 4 is fixedly connected to the inner ring surface of the first bearing 3, the drive motor 6 is fixedly connected to the surface of the base plate 5, the drive end of the drive motor 6 is fixedly connected to the end face of the take-up roller 4, one end of the moving screw 17 is fixedly connected to the inner ring surface of the positioning bearing 16, and the end face of the support plate 18 is fixedly connected to the outer ring surface of the positioning ring 13. First, the mounting bracket 2 is fixedly connected to the side of the workbench 1 by bolts. Then, by starting the drive motor 6, the first bearing 3 is used to drive the take-up roller 4 to rotate. The drive motor 6 is powered by an external power supply. In addition, the positioning bearing 16 is used to rotate the moving screw 17. By rotating the moving screw 17, the height of the support plate 18 can be adjusted. By adjusting the height of the support plate 18, the height of the positioning ring 13 can be adjusted. Thus, by adjusting the height of the positioning ring 13, the height of the tension tube 12 can be adjusted in conjunction with the tension spring 14, thereby facilitating the adjustment of the tension force on the enameled wire.

[0020] Please see Figures 1-5 As shown, one end of the tension spring 14 is fixedly connected to the surface of the positioning ring 13, and the other end of the tension spring 14 is provided with a push plate 19. A positioning plate 20 is provided on the side of the push plate 19. The positioning plate 20 has a "U" shaped plate structure. A limit block 21 is provided on the side of the positioning plate 20. The limit block 21 has an "L" shaped plate structure. When the lifting plate 9 is sleeved on the guide rod 8, the limit block 21 is fixedly connected to the side of the positioning plate 20 by a limit bolt. Thus, the "L" shaped structure of the limit block 21 facilitates the limitation of the upper surface of the lifting plate 9, preventing the lifting plate 9 from separating from the push plate 19 and improving displacement stability.

[0021] Please see Figure 7 As shown, the lifting plate 9 is slidably connected to the guide rod 8, and a limiting ring 22 is sleeved on the surface of the support rod 10. The tension tube 12 is fixedly connected to the outer ring surface of the second bearing 11. The second bearing 11 facilitates the rotation of the tension tube 12. The rotation of the tension tube 12 reduces the friction on the enameled wire. The limiting ring 22 helps to limit the enameled wire and prevents the enameled wire from falling off the tension tube 12.

[0022] Through the above-described solution of this utility model, one end of the enameled wire is first wound around the take-up roller 4, and then the enameled wire is supported by the tension tube 12. The lifting plate 9 is moved upward by the elastic force of the tension spring 14, so that the tension tube 12 always keeps the enameled wire taut and avoids the problem of loose winding of the enameled wire. With the help of the positioning bearing 16, it is easy to rotate the moving screw 17 and adjust the position of the positioning ring 13 on the guide rod 8, so as to adjust the magnitude of the upward elastic force of the tension spring 14 on the tension tube 12 and adjust the tension force on the enameled wire. The elastic force of the tension spring 14 makes it easy for the tension tube 12 to always be in contact with the enameled wire to keep it taut, and avoids the tension tube 12 being fixed and affecting the tension and winding of the enameled wire.
