Description

Technical Field

[0001] This utility model relates to a watch strap polishing device, specifically a single-strand watch strap re-polishing device. Background Technology

[0002] During the processing of watch straps, after each individual strap is polished, it needs to be assembled. Several straps are then assembled into a whole before inspection. The above polishing process has the following drawbacks: if an individual strap is found to be improperly polished during inspection, because the entire strap is already assembled, the individual straps on it cannot be directly re-polished; otherwise, the remaining straps would also need to be re-polished repeatedly. Therefore, the individual strap must be disassembled before re-polishing, which involves multiple steps, resulting in a cumbersome and inefficient rework process. Therefore, improvements are needed. Utility Model Content

It can simultaneously adjust the position of the watch strap in both the horizontal and vertical directions, and can also rotate the watch strap axially. Therefore, it can accurately re-grind any single strand of the watch strap without disassembling the entire watch strap, while ensuring the integrity of the remaining straps. This shortens the rework time, greatly improves the processing efficiency, and solves the problems of cumbersome process and low efficiency in the re-grinding of watch straps in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-strand watch strap re-grinding device, comprising a frame and a watch strap control mechanism and a re-grinding mechanism disposed on the frame. The watch strap control mechanism comprises a support assembly, a first screw, a lifting assembly, a rotating assembly, and an adjusting plate arranged sequentially from bottom to top.

[0023] Please see Figure 1 One embodiment of this utility model is a single-strand watch strap re-wearing device, which includes a frame 1 and a watch strap control mechanism 2, a re-wearing mechanism 3 and a control box 4 disposed on the frame 1.

[0024] Please see Figures 2 to 3 The watch strap control mechanism 2 includes a support assembly 21, a first screw 22, a lifting assembly 23, a rotating assembly 24, and an adjusting plate 25 arranged sequentially from bottom to top. The support assembly 21 includes a platform 211 and a horizontal plate 212, both horizontally positioned. The horizontal plate 212 is fixed to the platform 211 by the first screw 22. The platform 211 has several sets of screw holes for installing the first screw 22. The distance between different screw holes and the re-grinding mechanism 3 is different. Therefore, by installing the first screw 22 into different screw holes, the distance between the watch strap control mechanism 2 and the re-grinding mechanism 3 can be adjusted to meet different watch strap polishing requirements. The platform 211 is fixed to the upper surface of the frame 1. The lifting assembly 23 includes a first sleeve 231 and a second sleeve 232. The first sleeve 231 has an opening at the top and an internal... The hollow cavity structure allows the second sleeve 232 to slide vertically on the first sleeve 231. The bottom of the second sleeve 232 is connected to the first sleeve 231 via a spring 233, which is vertically positioned within the cavity of the first sleeve 231. The bottom of the second sleeve 232 extends into the cavity of the first sleeve 231 and fits against the inner wall of the cavity, ensuring that the second sleeve 232 can only slide vertically under the action of the spring 233. The rotating assembly 24 includes a bearing 241, a rotating head 242, and a shaft 243 for connecting the bearing 241 and the rotating head 242. The bearing 241 is fixed to the upper end face of the second sleeve 232, and the rotating head 242 is fixed to the lower end face of the adjusting plate 25. A support platform 26 is provided on the adjusting plate 25, and a notch is provided at the center of the upper end face of the adjusting plate 25, into which the support platform 26 extends.

[0025] Please see Figure 4The re-grinding mechanism 3 includes a re-grinding motor 31, the output end of which is connected to a grinding wheel 32. The re-grinding motor 31 is fixed on the upper platform 33, which is fixed on the upper end face of the frame 1. The grinding wheel 32 has a ring-shaped design, and a sandpaper layer 34 is fixed on the outer circle of the grinding wheel 32. The sandpaper layer 34 contacts the watch strap to grind the watch strap. The control box 4 is fixed on the frame 1 and is electrically connected to the re-grinding motor 31. The structure of the control box 4 is existing technology and will not be described in detail here.

[0026] Please see Figure 5 The support platform 26 is fixed to the adjustment plate 25 by a horizontally set second screw 27. In actual installation, the threaded part of the second screw 27 passes through the support platform 26 and the adjustment plate 25, fixing the support platform 26 to the adjustment plate 25. Therefore, the support platform 26 can also be removed from the adjustment plate 25.

[0027] Please refer to the following: Figures 1 to 5 In the operation of this utility model, the watch strap is fixed to the upper surface of the support platform 26. The re-grinding motor 31 is driven to run, which drives the grinding wheel 32 and the sandpaper layer 34 on it to rotate. This allows the part of the watch strap extending from the support platform 26 to contact the sandpaper layer 34 and be polished. The height of the support platform 26 and the watch strap on it can be adjusted by the spring 233. By changing the position of the platform 211 on the upper surface of the frame 1, the platform 211 can be moved closer to or further away from the sandpaper layer 34, thereby adjusting the horizontal orientation of the support platform 26 and the watch strap on it. This allows the watch strap to make precise contact with the sandpaper layer 34. The rotating head 242 and the support platform 26 on it are rotated by the rotating shaft 243, which causes the watch strap to rotate axially. Therefore, the position of the watch strap can be adjusted in multiple directions, so that all parts of the watch strap surface can be fully polished. The way the watch strap is fixed on the support platform 26 is existing technology and will not be described in detail here.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
