[0021] 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.

[0022] Please see Figure 1-4 A perforation device for shoe production includes a support assembly and a perforation assembly. The support assembly includes a worktable 1, support legs 2, side plates 3, and a top plate 4. The support legs 2 are located at the four corners below the worktable 1. Two sets of symmetrically arranged side plates 3 are located above the worktable 1, and the top plate 4 is located above the two sets of side plates 3. The perforation assembly includes a lifting device 5, a sliding frame 6, a worm gear 7, a worm 8, a screw 9, a slider 10, a motor 11, a connector, and a perforation rod 12. The two sets of side plates 3 have U-shaped grooves on the side closest to the center of the worktable 1. The output end of the lifting device 5 passes through the top plate 4 and is connected to the sliding frame 6. The left and right sides of the sliding frame 6 are slidably connected to the U-shaped grooves. A sliding groove is provided below the frame 6. The worm gear 7 and two sets of symmetrically arranged screws 9 are arranged in the sliding groove. One end of the two sets of screws 9 is connected to the center of the worm gear 7, and the other end of the two sets of screws 9 is rotatably connected to the inner sidewall of the sliding groove. The sliders 10 are arranged in two symmetrical sets. The sliders 10 are inverted T-shaped. The upper part of the sliders 10 is inserted into the sliding groove and threadedly connected to the screws 9. A worm 8 that meshes with the worm gear 7 is also provided in the sliding groove. The output end of the motor 11 passes through the sliding frame 6 and is connected to the worm 8. A slot adapted to the punching rod 12 is provided below the slider 10. A connector for fixing the punching rod 12 is also provided on the slider 10.

[0023] Initially, the support leg 2 provides stable support for the workbench 1, and the workbench 1 provides stable support for the side plate 3. There are commercially available support components for supporting and fixing shoe uppers and feeding the punching device; these will not be elaborated upon here. This paper only provides a punching device that facilitates adjustment of the spacing between the punching rods 12 and easy assembly and disassembly of the punching rods 12. The motor 11 (servo motor 11) is started, and its output drives the worm gear 8 to rotate. The worm gear 8 meshes with the worm wheel 7 in the slide groove of the slide frame 6. The worm wheel 7 and worm gear 8 have good self-locking capability, thereby driving the two sets of symmetrically arranged screws 9 connected to the center of the worm wheel 7 to rotate. The slider 10 is inserted into the slide groove and threadedly connected to the screws 9. When the screws 9 rotate, the two sets of sliders 10 move towards each other. Since the sliders 10 are set in two symmetrical arrangements, the spacing between the two sets of punching rods 12 can be changed by adjusting the position of the sliders 10. The servo motor 11 has high-precision position control capability, which can accurately control the movement distance of the slider 10 according to the shoelace hole punching requirements of different shoe uppers, thereby realizing the accurate adjustment of the spacing of the punching rod 12;

[0024] The punch rod 12 and the slider 10 are connected by a connector for easy disassembly and assembly, so as to replace punch rods 12 of different shapes. During the punching operation, the U-shaped groove of the side plate 3 is slidably connected to the slide frame 6 to ensure the stability of the slide frame 6. The lifting device 5 drives the slide frame 6 to move downward under the support of the top plate 4, and the slider 10 drives the punch rod 12 to move downward to complete the punching operation on the inclined surface.

[0025] In actual use, a guide block 13 is provided at the end of the slot away from the connector. The punching rod 12 is provided with a guide groove that matches the guide block 13. The punching rod 12 to be used is inserted into the slot below the slider 10. The guide block 13 at the end of the slot away from the connector matches the guide groove on the punching rod 12, ensuring that the installation position of the punching rod 12 is accurate.

[0026] In this embodiment, the connector includes an elastic element, a support plate 14, a plug rod 15, and a handle 16. The slider 10 has two sets of symmetrically arranged elastic elements on its front side. The support plate 14 is mounted on each set of elastic elements, and a plug rod 15 penetrating the slot is mounted on the support plate 14. The punching rod 12 also has a pin hole adapted to the plug rod 15. The handle 16 is located at the end of the support plate 14 away from the plug rod 15. Initially, the elastic element is in a contracted state. When the punching rod 12 needs to be inserted, the support plate 14 is pulled by the handle 16, and the elastic element springs back to its original position. When the elastic element extends, the insertion rod 15 is not inserted into the slot. When the punching rod 12 is fully inserted into the slot, the handle 16 is released, and the insertion rod 15 is inserted into the pin hole of the punching rod 12, thus completing the fixing of the punching rod 12. In this embodiment, the elastic element includes a spring 17 and a telescopic rod 18. The spring 17 is sleeved on the telescopic rod 18. Both ends of the spring 17 and the telescopic rod 18 are respectively connected to the slider 10 and the support plate 14. The telescopic rod 18 can be a damped telescopic rod 18. The spring 17 facilitates the reciprocating movement of the support plate 14, and the telescopic rod 18 ensures the stability of the movement of the support plate 14.
