Description

Technical Field

[0001] This utility model relates to the field of shoe upper punching technology, specifically a shoe upper punching device. Background Technology

[0002] During the production of shoe uppers, a punching machine is needed to punch holes in the shoe laces. First, the un-punched shoe upper is placed on a table, and the position of the punch head of the punching machine is adjusted so that its position corresponds to the shoe lace holes on the shoe upper. Then, punching can be performed on subsequent batches of shoe uppers.

[0003] Chinese utility model patent, authorized announcement number CN223084969U, discloses a shoe upper punching device that can position the shoe upper on the table. When the shoe upper is placed later, the position of the shoe lace hole can correspond to the position of the punching head, which makes it less likely for the shoe lace hole to shift during the punching process, thereby improving the production yield of shoe uppers.

[0004] Existing shoe upper punching devices still have certain defects in practical applications. For example, when punching holes to limit the shoe upper, the top of the shoe upper may become arched and uneven. Direct punching may cause the shoelace holes to shift, thereby reducing the production yield of shoe uppers. Utility Model Content

[0005] The purpose of this invention is to provide a shoe upper punching device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shoe upper punching device, comprising a workbench, a support frame, and a punching mechanism, wherein a support platform is fixed at the top of the workbench, and a plurality of horizontally distributed first pressure rods are fixed at the top of the support platform.

[0007] The bottom of the punching mechanism is equipped with flattening components on both sides. After the flattening components flatten the shoe surface, the punching head of the punching mechanism punches holes in the shoe surface.

[0008] Preferably, an arc-shaped pressure block is also fixed to the top of the support platform.

[0009] Preferably, the top of the support platform is also provided with several side pressing members, and the first pressing rod and the side pressing members are both located in the side groove of the shoe upper.

[0010] Preferably, the side pressing member includes a support base, on which a bidirectional lead screw is movably connected, and a worm gear is fixed on the body of the bidirectional lead screw;

[0011] A worm gear is movably connected to the top of the support platform, and the worm gear meshes with a worm wheel;

[0012] The top of the support platform is equipped with two sliders. The two sides of the double-acting screw are respectively screwed to the sliders. A second pressure rod is fixed to the side of the slider.

[0013] Preferably, the flattening assembly includes two side plates, and several extension plates are formed on the opposite sides of the two side plates. Insert rods are movably inserted into the plates of the extension plates, and fixing blocks and pressure plates are fixed at the top and bottom ends of the insert rods, respectively.

[0014] A spring is fixed between the extension plate and the fixing block.

[0015] Preferably, the extension plate is located on one side of the two outermost punch heads and between two adjacent punch heads.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This shoe upper punching device is equipped with a flattening component. When the punching mechanism is activated, the driving component moves the punching head and the flattening component downwards synchronously. The pressure plate in the flattening component first contacts the shoe upper and flattens it. After the pressure plate completely flattens the shoe upper, the punching head continues to move downwards to perform punching operations on the designated positions of the shoe upper. This effectively eliminates shoe upper wrinkles before punching, avoids punching offset problems caused by uneven shoe uppers, and improves punching accuracy and yield.

[0018] Meanwhile, a first pressing rod, a side pressing component, and a pressing block are provided.

[0024] 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.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a shoe upper punching device, including a workbench 1, a support frame 2, and a punching mechanism 3. A support platform 4 is fixed at the top of the workbench 1. The punching mechanism 3 includes a driving component and a punching head 301. The driving component drives the punching head 301 to move vertically to punch the shoe upper. The specific structure of the support platform 4 and several punching heads 301 is prior art and will not be described in detail here (for details, please refer to the multi-functional punching machine disclosed in Chinese Patent No. CN202020895259.8).

[0026] To limit the position of the shoe upper 6, several horizontally distributed first pressing rods 502 are fixed at the top of the support platform 4, and an arc-shaped pressing block 501 is fixed at the top of the support platform 4. To further improve the stability of the shoe upper 6, several side pressing parts 503 are also provided at the top of the support platform 4. It is known that the first pressing rods 502 and the side pressing parts 503 are located in the side grooves 601 of the shoe upper 6, and the pressing block 501 is located on the outermost side of the shoe upper 6.

[0027] like Figure 2 and Figure 3As shown, the side pressing member 503 includes two support seats 5031, with a bidirectional lead screw 5032 movably connected between the two support seats 5031. A worm gear 5033 is fixed on the rod of the bidirectional lead screw 5032. A worm 5034 is movably connected to the top of the support platform 4, and the worm 5034 meshes with the worm gear 5033. Two sliders 5035 are provided on the top of the support platform 4, with the bottom end face of the slider 5035 contacting the top end face of the support platform 4. The two sides of the bidirectional lead screw 5032 are respectively movably screwed to the sliders 5035. In addition, a second pressing rod 5036 is fixed to the side of the slider 5035. Specifically, due to the different opening widths of the side grooves 601, the pressing position of the second pressing rod 5036 against the side grooves 601 needs to be adjusted. The specific adjustment method is as follows: rotate the worm gear 5034, which drives the worm wheel 5033 meshing with it to rotate. The worm wheel 5033 drives the double-acting screw 5032 to rotate synchronously. When the double-acting screw 5032 rotates, the sliders 5035 on both sides move towards or away from each other along the top surface of the support platform 4, thereby driving the second pressing rod 5036 to move until the second pressing rod 5036 is tightly against the inner wall of the side groove 601, so as to achieve the adaptive pressing of the side grooves 601 with different widths.

[0028] like Figure 1 and Figure 4 As shown, flattening components are provided on both sides of the bottom of the punching mechanism 3. After the flattening components flatten the shoe upper 6, the punching head 301 of the punching mechanism 3 punches holes in the shoe upper 6.

[0029] The flattening assembly includes two side plates 701, and several extension plates 702 are formed on the opposite sides of the two side plates 701. The extension plates 702 are located on one side of the two outermost punch heads 301 and between two adjacent punch heads 301. Insert rods 703 are movably inserted into the plate body of the extension plates 702. The top and bottom ends of the insert rods 703 are respectively fixed with a fixing block 705 and a pressure plate 704. The pressure plate 704 is located at the bottom of the punch head 301. A spring 706 is fixed between the extension plates 702 and the fixing block 705, and the insert rods 703 are located inside the spiral coil of the spring 706.

[0030] Working principle: The side abutment 503 is adjusted according to the width of the side groove 601 to adjust the position of the second abutment rod 5036. The shoe upper 6 to be punched is placed on the top of the support platform 4, so that the side groove 601 of the shoe upper 6 is fitted outside the first abutment rod 502 and the side abutment 503. The arc-shaped abutment block 501 contacts the edge of the shoe upper 6 to limit the shoe upper 6. The punching mechanism 3 is started, and the driving component drives the punching head 301 and the flattening assembly to move down synchronously. The pressure plate 704 in the flattening assembly first contacts the shoe upper 6. As the punching mechanism 3 continues to move downwards, the insertion rod 703 slides upwards along the extension plate 702. The spring 706 is compressed and generates an elastic restoring force, causing the pressure plate 704 to apply continuous downward pressure to the shoe upper 6, flattening the shoe upper 6. After the pressure plate 704 has completely flattened the shoe upper 6, the punching head 301 continues to move downwards to perform punching operations at designated positions on the shoe upper 6. After punching is completed, the driving component drives the punching head 301 and the flattening assembly upwards, the spring 706 returns to its original state, and the pressure plate 704 separates from the shoe upper 6, allowing the processed shoe upper 6 to be removed. By setting adjustable side pressure members 503 and multi-position distributed flattening assemblies, it can not only adapt to the positioning requirements of shoe uppers of different specifications, but also effectively eliminate wrinkles on the shoe upper 6 before punching, avoiding punching offset problems caused by uneven shoe uppers, thus improving punching accuracy and yield.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
