[0047] The base 1 is provided with a first groove 11, and a guide mechanism 5 is provided in the first groove 11;

[0048] The guide mechanism 5 includes a plurality of first guide rail plates 51 and second guide rail plates 52, wherein the first guide rail plates 51 are arranged along the Y-axis direction, and the second guide rail plates 52 are arranged along the X-axis direction, the second guide rail plates 52 are fixedly connected to one end of the adjacent first guide rail plates 51, and any two adjacent second guide rail plates 52 are staggeredly connected, the second guide rail plates 52 are retractable structures, and the upper end surfaces of the first guide rail plates 51 and the second guide rail plates 52 are provided with guide rail grooves 53;

[0049] The base 1 is provided with a moving mechanism 4 which is slidably disposed on the base 1, and the moving mechanism 4 is slidably disposed in the guide rail groove 53;

[0050] The moving mechanism 4 is provided with a workbench 9 for placing the shoe upper.

[0051] During use, the moving mechanism 4 moves in the guide rail groove 53. When punching multiple rows of holes, the distance between adjacent holes can be controlled to improve the accuracy of the punching.

[0052] Preferably, fixing mechanisms 6 for fixing the upper are provided at both ends of the workbench 9;

[0053] The fixing mechanism 6 includes a fixing plate 61, which is rotatably set on the workbench 9.

The two ends of the tension spring 62 are respectively fixedly connected to the second groove 91 and the fixing plate 61. A pressing plate 63 is fixedly connected to the top of the fixing plate 61.

[0054] The pressing plate 63 is pressed downward, and the pressing plate 63 drives the fixing plate 61 to rotate along the workbench 9. The tension spring 62 at the bottom of the fixing plate 61 is stretched, and the two ends of the shoe upper are respectively placed under the fixing plates 61 at both ends of the workbench 9. The pressing plate 63 is slowly released, and the lower end surface of the fixing plate 61 rotates and contacts with the shoe upper under the elastic recovery action of the tension spring 62 to fix the shoe upper.

[0055] Preferably, the moving mechanism 4 includes a first moving platform 41, a first slide groove 42 is provided on the upper end surface of the base 1 along the X-axis direction, a first slider 43 is fixedly provided at the bottom of the first moving platform, the first moving platform 41 is slidably arranged in the first slide groove 42 through the first slider 43, a first stepper motor 44 is provided on the base 1, and an output end of the first stepper motor 44 is fixedly connected to the first moving platform 42;

[0056] A second moving platform 45 is provided on the first moving platform 41, a second slide groove 46 is provided on the upper end surface of the first moving platform 41 along the Y-axis direction, a second slider 47 is fixedly provided at the bottom of the second moving platform 45, and the second moving platform 45 is slidably arranged in the second slide groove 46 through the second slider 47, a second stepping motor 48 is provided on the first moving platform 41, and an output end of the second stepping motor 48 is fixedly connected to the second moving platform 45;

[0057] The workbench 9 is arranged on the top of the second moving platform 45 .

[0058] By setting the moving frequency of the second stepper motor 48, it can be ensured that the distances between adjacent holes are the same, thereby improving the accuracy of punching. When the moving mechanism 4 moves to the end along the guide groove 53 of the first guide plate 51, the first stepper motor 44 starts to push the moving mechanism 4 to move along the X direction, sliding from the guide groove 53 of the second guide plate 52 to the guide groove 53 of the adjacent first guide plate 52. At this time, the second stepper motor 48 is started to move in the opposite direction to punch the second row of holes. This reciprocating movement is used to achieve multiple rows of punching and improve the accuracy of the distances between adjacent holes and adjacent rows of holes.

[0059] Preferably, two first sliders 43 are provided, symmetrically arranged at the two ends of the bottom of the first moving platform 41; two second sliders 47 are provided, symmetrically arranged at the two ends of the bottom of the second moving platform 45. Providing two first sliders 43 and two second sliders 47 improves the stability of the first moving platform 41 and the second moving platform 45 during movement.

[0060] Preferably, a first through slot 49 is formed on the first movable platform 41 , and a third sliding block 410 is fixedly provided at the bottom of the second movable platform 45 . The third sliding block 410 penetrates the first through slot 49 and is slidably disposed in the guide rail slot 53 .

[0061] Preferably, the first guide rail plate 51 in the guide mechanism 5 away from the support frame 2 is fixedly arranged in the first groove 11, the bottom of the remaining first guide rail plates 51 is fixedly connected with a fourth slider 54, the base 1 is rotatably provided with a threaded rod 12, the fourth slider 54 is rotatably connected with the threaded rod 12 and moves in the first groove 11 along the X-axis direction when the threaded rod 12 rotates;

[0062] One end of the threaded rod 12 extends out of the base 1 and is rotatably provided with a rotating handle 8 .

[0063] Rotating the handle 8 drives the threaded rod 12 to rotate, thereby driving the first slider 54 threadedly connected thereto to move. Because the second guide groove 52 is a retractable structure, it drives the unfixed first guide plate 51 to move, which can adapt to the requirements of multiple rows of punching at different distances and improve the practicality of the device.

[0064] Preferably, the fourth slider 54 is arranged in the middle of the bottom of the first guide plate 51, and the fifth sliders 55 are arranged at both ends of the bottom of the first guide plate 51. The base 1 is provided with a slide rod 13, and the fifth slider 55 is slidably connected to the slide rod 13. The fifth sliders 55 are arranged at both ends of the bottom of the first guide plate 51 to improve the stability of the first guide plate 51.

[0065] Preferably, the lower end of the connecting rod 22 is fixedly connected to a support seat 23, and the punching rod 3 is arranged at the bottom of the support seat 23;

[0066] The bottom of the support seat 23 is provided with a local fixing mechanism 7, which includes a fixing rod 71, which is fixedly arranged on the lower end surface of the support seat 2, and a buffer sleeve 72 is slidably connected to the side of the fixing rod 71. A first spring 73 is sleeved on the outer side of the fixing rod 71, and the two ends of the first spring 73 are respectively fixedly connected to the support seat 23 and the buffer sleeve 72. During the punching process, the buffer sleeve 72 first contacts the shoe surface to fix the position to be punched, so as to avoid the position of the shoe surface being offset due to the excessive impact of the punching rod 3 during the punching process.

[0067] The working principle of the utility model is as follows: before punching, the threaded rod 12 is rotated by rotating the rotating handle 8, thereby driving the first slider 54 threadedly connected thereto to move, and because the second guide groove 52 is a retractable structure, the first guide plate 51 that is not fixed is driven to move, and the distance between adjacent first guide plates 51 is adjusted, and the shoe upper to be punched is fixed on the workbench 9 through the fixing mechanism 6, and the first cylinder 21 is started to drive the support seat 23 to move downward, and the buffer sleeve 72 first contacts the shoe upper to fix the position to be punched, and then the punching rod 3 punches the shoe upper to avoid excessive impact of the punching rod 3 during the punching process. This causes the position of the shoe upper to shift. After the punching is completed, the first cylinder 21 drives the punching rod 3 and the buffer sleeve 72 to move upward, and the second stepper motor 48 is started to drive the second moving platform to drive the workbench to move a fixed distance in the Y direction for the second punching. After a row of punching is completed, the first stepper motor 44 is started to drive the moving mechanism 4 to move in the X direction, sliding from the guide groove 53 of the second guide plate 52 to the guide groove 53 of the adjacent first guide plate 52, and the second stepper motor 48 is started again to move in the opposite direction to punch the second row of holes. This is repeated to achieve multiple rows of punching on the shoe upper, and the accuracy and efficiency of the punching are improved.

[0068] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
