A punching platform is fixedly connected to the front of the punching device frame, and a clamp is fixedly installed at the upper end of the punching platform. A hydraulic telescopic rod is fixedly connected to the top of the punching device frame. The hydraulic telescopic rod consists of a fixed end and a telescopic end. The fixed end of the upper end of the hydraulic telescopic rod is fixedly connected to the punching device frame, and a fixed plate is fixedly connected to the outside of the fixed end. A through rod that moves through the punching blades is fixedly connected to the bottom of the fixed plate. Two sets of guide plates are also symmetrically and movablely installed on the front of the punching device frame. This utility model can automatically discharge residual shoe upper waste material inside the punching blades during the shoe upper punching process and guide it to a designated position via inclined guide plates, preventing waste material from clogging the punching blades and affecting the subsequent punching effect, thus significantly improving practical performance.

[0003] However, the device has some shortcomings in use. The fabric lacks a limit when placed on the device, which can easily cause positional deviation. At the same time, fabric wrinkles can affect the punching accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a punching machine for shoe fabric production, which solves the problems of lack of limiting position when the fabric is placed on the device, which easily causes positional deviation, and fabric wrinkles affecting punching accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching machine for shoe upper production, comprising a base plate, a support fixedly connected to the upper end of the base plate, a frame fixedly connected to the upper end of the base plate, a cylinder fixedly mounted on the upper end of the frame, a cylinder rod passing through the frame and slidably connected to the frame, a hanging plate fixedly connected to the lower end of the cylinder rod, a punch fixedly connected to the lower end of the hanging plate, a tensioning mechanism provided on the hanging plate, a hanging rod slidably connected inside the hanging plate, a pressure frame fixedly connected to the lower end of the hanging rod, and a compression spring provided on the outer side of the hanging rod.

[0006] Preferably, the pressure frame and the support are in contact, and the pressure frame has a hollow cylindrical structure. The pressure frame limits the movement of the fabric.

[0007] Preferably, one end of the compression spring is fixedly connected to the hanging plate, and the other end of the compression spring is fixedly connected to the pressure frame. By setting the compression spring, the pressure frame is elastically pressed down.

[0008] Preferably, the tensioning mechanism includes a guide block, which is slidably connected inside the hanging plate, and a guide rod is fixedly connected inside the hanging plate. The guide rod and the guide block are slidably connected, and a spring is provided on the outer side of the guide rod. A sliding plate is fixedly connected to the lower end of the guide block. The spring acts on the guide block, causing the pressure roller to move downwards and engage with the inclined surface at the upper end of the support. This allows the pressure roller to push the fabric at the upper end of the support to flatten and tension it, resulting in more precise fabric punching.

[0009] Preferably, one end of the spring is fixedly connected to the hanging plate, and the other end of the spring is fixedly connected to the guide block. By setting the spring, the guide block is elastically compressed.

[0010] Preferably, a slider is fixedly connected to the upper end of the skateboard, and the slider contacts the hanging plate. By setting the slider, the friction between the skateboard and the hanging plate is reduced.

[0011] Preferably, a side plate is fixedly connected to the lower end of the slide plate, and a pressure roller is fixedly connected to the side plate. The fabric is tensioned by setting the pressure roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses the elastic action of a compression spring on the pressure frame, so that the pressure frame can press the fabric onto the support, limit the position of the fabric, and prevent the fabric from moving on the support.

[0014] 2. This utility model uses a spring acting on the guide block to make the pressure roller move down and cooperate with the inclined surface at the upper end of the support. This allows the pressure roller to push the fabric at the upper end of the support to be laid flat and tensioned, making the fabric punching more precise. Attached Figure Description

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.

[0021] Please see Figures 1-3 A punching machine for shoe fabric production includes a base plate 1, a support 2 fixedly connected to the upper end of the base plate 1, a frame 3 fixedly connected to the upper end of the base plate 1, a cylinder 4 fixedly mounted on the upper end of the frame 3, a cylinder rod of the cylinder 4 passing through the frame 3 and slidably connected to the frame 3, a hanging plate 5 fixedly connected to the lower end of the cylinder rod of the cylinder 4, a punch 6 fixedly connected to the lower end of the hanging plate 5, a tensioning mechanism 7 provided on the hanging plate 5, a hanging rod 8 slidably connected inside the hanging plate 5, a pressure frame 9 fixedly connected to the lower end of the hanging rod 8, the pressure frame 9 contacting the support 2, the pressure frame 9 having a hollow cylindrical structure, the pressure frame 9 limiting the fabric position, a compression spring 10 provided on the outer side of the hanging rod 8, one end of the compression spring 10 fixedly connected to the hanging plate 5, and the other end of the compression spring 10 fixedly connected to the pressure frame 9, the compression spring 10 causing the pressure frame 9 to be elastically pressed down.

[0022] Please see Figures 1-4 The tensioning mechanism 7 includes a guide block 71. The guide block 71 is slidably connected inside the hanging plate 5. A guide rod 72 is fixedly connected inside the hanging plate 5. The guide rod 72 and the guide block 71 are slidably connected. A spring 73 is provided on the outer side of the guide rod 72. One end of the spring 73 is fixedly connected to the hanging plate 5, and the other end of the spring 73 is fixedly connected to the guide block 71. By providing the spring 73, the guide block 71 is elastically compressed. A sliding plate 74 is fixedly connected to the lower end of the guide block 71, and a sliding plate 74 is fixedly connected to the upper end of the sliding plate 74. The slider 75 contacts the hanging plate 5. By setting the slider 75, the friction between the slide plate 74 and the hanging plate 5 is reduced. The lower end of the slide plate 74 is fixedly connected to the side plate 76, and the side plate 76 is fixedly connected to the pressure roller 77. By setting the pressure roller 77, the fabric is tensioned. Through the action of the spring on the guide block 71, the pressure roller 77 moves down and cooperates with the upper inclined surface of the support 2. This allows the pressure roller 77 to push the fabric to be laid flat and tensioned on the upper part of the support 2, making the fabric punching more accurate.

[0023] The specific implementation process of this utility model is as follows: In use, manually move the pressure frame 9 upwards, so that the pressure spring 10 is compressed on the pressure frame 9. Then, place the fabric on the support 2, release the pressure frame 9, and the elastic action of the pressure spring 10 on the pressure frame 9 will allow the pressure frame 9 to press the fabric onto the support 2, limiting the position of the fabric and preventing it from moving on the support 2. Then, start the cylinder 4. The cylinder 4 drives the cylinder rod to extend, and the cylinder rod drives the hanging plate 5 to move downwards. The hanging plate 5 drives the sliding plate 74 to move downwards, and the sliding plate 74 drives the side plate. As plate 76 moves downward, side plate 76 drives pressure roller 77 to move downward and contact the fabric, pressing the fabric onto the inclined surface of support 2. Hanging plate 5 continues to move downward, causing guide roller 77 to slide relative to the inclined surface of support 2, pushing the fabric to move on the inclined surface. Then punch 6 moves downward and slides relative to pressure frame 9 to contact the fabric, punching the fabric. Through the action of spring on guide block 71, pressure roller 77 moves downward and cooperates with the upper inclined surface of support 2, allowing pressure roller 77 to push the fabric to be flattened and tensioned on the upper part of support 2, making the fabric punching more precise.
