Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoe processing technology, and in particular to a wheel clamp device that facilitates the protection of shoe decorative buckles. Background Technology
[0002] In the extremely precise and complex production process of the shoe manufacturing industry, the processing precision of shoe decorative buckles and the protective effect they provide are undoubtedly core elements that directly determine the overall aesthetics and durability of shoes. Especially for shoes targeting the high-end market, the precise positioning of decorative buckles, their flawless surface, and their seamless fit with the shoe upper are indispensable and must meet high standards. However, in the traditional process of processing shoe uppers, the wheel used during the sewing operation often inevitably leaves some embossing marks on the decorative buckles. This not only affects the appearance of the decorative buckles but may also negatively impact their protective function. More importantly, the position of the wheel is fixed, and this design limitation greatly restricts the flexibility of operation. It prevents workers from flexibly adjusting the position of the wheel according to the actual thickness of different shoe uppers to adapt to diverse production needs. This fixed wheel position not only affects production efficiency but may also lead to an unsatisfactory fit between the decorative buckle and the shoe upper, thus affecting the quality of the final product and its market competitiveness.

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] like Figures 1-5 As shown, this embodiment provides a wheel clamp device for protecting shoe decorative buckles, including a mounting sleeve 1, a movable rod 2 inserted into the mounting sleeve 1, a connecting frame 3 at one end of the movable rod 2, a wheel 4 mounted on the connecting frame 3, a limit wheel 5 meshing on the wheel 4 to limit the wheel 4, the limit wheel 5 being connected to the movable rod 2, a spring 6 mounted on the other end of the movable rod 2, the other end of the spring 6 being connected to the mounting sleeve 1, allowing flexible adjustment of the length of the movable rod 2 inserted inside the mounting sleeve 1, and a rubber sleeve 7 fitted on the wheel 4 to effectively absorb and disperse impact force, avoiding unnecessary damage to the fabric and decorative buckles, thereby improving the overall processing quality.
[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 1 As shown, the inner wall of the mounting sleeve 1 has a limiting groove 8, and the moving rod 2 has limiting blocks 9 on both sides. The limiting blocks 9 are slidably engaged in the limiting groove 8. The moving rod 2 has a screw 11, which is inserted into the mounting sleeve 1. A clamping nut 10 is threaded onto the screw 11, and the clamping nut 10 is pressed against the mounting sleeve 1. The mounting sleeve 1 has a limiting hole 12, and the screw 11 is inserted into the limiting hole 12. The rubber sleeve 7 has anti-slip strips 13 arranged in an array. The wheel 4 has an annular groove 14, and the rubber sleeve 7 and the wheel 4 are engaged through the annular groove 14 to prevent the rubber sleeve 7 from shifting during the compression process and ensure... The buffer force is evenly distributed. The rubber sleeve 7 is made of nitrile rubber. Adjusting the initial extension length of the moving rod 2, the moving rod 2 moves under the elastic restoring force of the spring 6. The screw 11 moves inside the limiting hole 12. The sliding snap-fit design of the limiting block 9 in the limiting groove 8 not only enhances the stability of the moving rod 2, but also ensures its smoothness during adjustment. The clamping nut 10 and the mounting sleeve 1 clamp together to fix the moving rod 2 and the mounting sleeve 1. The surface of the teeth of the limiting wheel 5 is coated with tungsten carbide. The upper end of the mounting sleeve 1 is provided with a mounting hole 15, which can fix this wheel clamp device to the external operating platform.
[0022] In use, the operator can securely fix the mounting sleeve 1 to the external operating platform using bolts through the mounting hole 15 at the upper end of the mounting sleeve 1. First, the operator needs to place the shoe upper to be processed stably on the operating platform, and then carefully align the wheel clamp device of this invention with the corresponding position of the shoe upper. Next, adjust the initial extension length of the moving rod 2 to adapt to the specific needs of the shoe upper. Under the elastic restoring force of the spring 6, the moving rod 2 will move accordingly. At the same time, the screw 11 moves precisely inside the limiting hole 12. The sliding engagement design of the limiting block 9 in the limiting groove 8 not only significantly enhances the overall stability of the moving rod 2, but also ensures its stability during adjustment. The smoothness and flexibility of the machine, along with the tight clamping fit between the clamping nut 10 and the mounting sleeve 1, allows the moving rod 2 to be firmly fixed together with the mounting sleeve 1. This enables it to flexibly adapt to shoe uppers of different thicknesses, ensuring that the wheel clamping equipment can fit tightly to the shoe upper and avoid any shaking or misalignment during processing. The rubber sleeve 7 is tightly pressed against the fabric, and when the wheel 4 starts to rotate, it can drive the shoe upper to move smoothly. The rubber sleeve 7 can also effectively absorb and disperse the impact force generated by the wheel 4 on the decorative buckle, thereby effectively preventing fabric damage or deformation of the decorative buckle due to excessive pressure. In addition, the insertion design of the screw 11 and the limiting hole 12 further enhances the stability and safety of the entire equipment, ensuring the smooth progress of the processing.
