[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0036] Refer to Figure 1 - Figure 3, An embodiment provided by the present utility model: A punching mechanism for polymer film processing, including a base 1, which serves as the support foundation for the entire mechanism. On both sides of the top end of the base 1, there are rotatably connected rollers. At the bottom end of the base 1, there are fixedly connected support columns 2, with four groups provided, which are used to support the top plate 3. The top ends of the support columns 2 are fixedly connected to the top plate 3, which is used to support the hydraulic cylinder. On the top end of the top plate 3, there is a hydraulic cylinder, which drives the moving plate 4 to move for punching operations. The bottom end of the output shaft of the hydraulic cylinder is fixedly connected to the moving plate 4, which is used to drive the tool 61 to perform punching operations. At the bottom end of the moving plate 4, there is a fixing component, and the fixing component includes a slide bar 52, which improves the stability of the operation of the first pressing frame 51. The outer wall of the slide bar 52 is slidably connected to the inner wall of the moving plate 4. There are four groups of slide bars 52, and the bottom ends of the four groups of slide bars 52 are fixedly connected to the first pressing frame 51, which is used to fix the upper side of the polymer film and improve the stability of the polymer film during punching.

[0037] Refer to Figure 2 and Figure 3 , The slide bar 52 and the moving plate 4 are elastically connected by a tension spring 53. Through the elastic force of the tension spring 53, the first pressing frame 51 can stably clamp the polymer film during the downward movement of the moving plate 4. At the bottom end of the rear side of the moving plate 4, there is a pressing column 54, and the bottom end of the pressing column 54 is set in a conical shape, which can cooperate with the groove at the top end of the pressing rod 55 to prevent the pressing column 54 from detaching from the pressing rod 55. Inside the inner wall of the top end of the rear side of the base 1, there is a slidably connected pressing rod 55 near the lower side of the pressing column 54. The pressing rod 55 slides inside the inner wall of the base 1, and the bottom end of the pressing rod 55 is hinged to a connecting rod 56.

[0038] Refer to Figure 3 and Figure 4 , The connecting rod 56 is set in a V shape. By driving the connecting rod 56, the second pressing frame 57 slides inside the inner wall of the base 1, so as to realize the cooperation between the second pressing frame 57 and the first pressing frame 51 to clamp the polymer film, facilitating the punching operation. The middle part of the connecting rod 56 is slidably connected to the inner wall of the base 1, and the front end of the connecting rod 56 is slidably connected to the second pressing frame 57, which is used in cooperation with the first pressing frame 51 to limit the lower side of the polymer film. The outer wall of the bottom end of the second pressing frame 57 is slidably connected to the inner wall of the base 1. The top end of the second pressing frame 57 and the bottom end of the first pressing frame 51 are made of rubber material, providing better sealing performance and friction force to ensure that the polymer film is firmly fixed, thereby improving the stability of the polymer film. There are two groups of the pressing column 54, the pressing rod 55 and the connecting rod 56, and the two groups of the pressing column 54, the pressing rod 55 and the connecting rod 56 are symmetrically arranged with the center line of the second pressing frame 57 as the axis of symmetry, ensuring uniform force on both sides of the second pressing frame 57 and better fixing effect.

[0039] Refer to Figure 3 and Figure 6, a mounting hole 7 is penetrated through the inner wall of the top end of the moving plate 4. The mounting holes 7 are evenly arranged on the moving plate 4, providing positions for the installation of the cutting tool 61. An installation component is arranged on the outer wall of the moving plate 4. The installation component includes installation columns 62, with four groups provided, and every two groups are arranged oppositely, for fixing the cutting tool 61. The outer wall of the installation column 62 slides on the inner wall of the mounting hole 7. The bottom end of the installation column 62 is fixedly connected with the cutting tool 61, for punching holes in the polymer film. A limiting groove is opened on the outer wall of the top end of the installation column 62, which is used in cooperation with the clamping plate 64 to limit the cutting tool 61. A fixing plate 63 is arranged at the top end of the installation column 62. The installation column 62 slides in the inner wall of the fixing plate 63. A clamping plate 64 is slidably connected to the inner wall of the fixing plate 63, for sliding in the inner wall of the limiting groove to limit the installation column 62. The side of the clamping plate 64 close to the installation column 62 is set as an inclined surface.

[0040] Refer to Figure 5 and Figure 6 , the inclined surface of the clamping plate 64 slides on the inner wall of the limiting groove. When the clamping plate 64 moves, the inclined surface will slide in cooperation with the inner wall of the limiting groove, so that the clamping plate 64 enters the limiting groove. A pulling plate 65 is fixedly connected to the side of the clamping plate 64 away from the installation column 62, which is convenient for the operator to pull the clamping plate 64, so as to quickly release the limit on the cutting tool 61. The pulling plate 65 slides in the inner wall of the fixing plate 63. There are two groups of the clamping plate 64 and the pulling plate 65. The two groups of pulling plates 65 are elastically connected by a return spring 66. The elastic force of the return spring 66 makes the clamping plate 64 stably inserted into the inner wall of the limiting groove, improving the stability of the clamping plate 64.

[0041] Working principle: When in use, first convey the polymer film through two groups of rollers. When punching is required, start the hydraulic cylinder to drive the moving plate 4 to move downward. While the moving plate 4 is moving, it drives the pressing column 54 to move downward, pressing down the pressing rod 55. The downward movement of the pressing rod 55 drives the connecting rod 56 to slide forward in the inner wall of the base 1, so that the front end of the connecting rod 56 moves upward and slides in the inner wall of the second pressing frame 57, thereby driving the second pressing frame 57 to move upward in the inner wall of the base 1. At this time, the moving plate 4 continues to move downward, and the second pressing frame 57 and the first pressing frame 51 on the moving plate 4 clamp the polymer film, improving the stability and flatness during clamping.

[0042] The sliding rod 52 slides in the inner wall of the moving plate 4 during the downward pressing process of the moving plate 4, stretching the tension spring 53, so that the cutting tool 61 performs punching operations on the polymer film. When the punching is completed, the hydraulic cylinder drives the moving plate 4 to rise, so that the first pressing frame 51 releases the clamping of the polymer film. The pressing column 54 moves upward, and the pressing rod 55 returns to its original position through the connecting rod 56 under the gravity of the second pressing frame 57 for the next operation.

[0043] When it is necessary to disassemble and maintain the punching position, pull the two groups of pull plates 65 to squeeze the return spring 66, so that the inclined surface of the clamping plate 64 slides out of the limiting groove, thereby releasing the limit on the four groups of mounting posts 62. At this time, the tool 61 can be withdrawn from the fixing plate 63 and the inner wall of the mounting hole 7, which is convenient for the operator to maintain the tool 61.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
