[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 - Figure 5 , the utility model provides a technical solution: Example 1:

[0027] A film punching device includes a base 1 and a punch 2. The punch 2 is fixedly mounted on the top of the base 1. A dovetail slide 3 is fixedly connected to the top of the base 1. An L-shaped support block 4 is slidably connected to the surface of the dovetail slide 3. A linkage block 5 is provided inside the L-shaped support block 4. Two clamping rods 6 are fixedly connected to the bottom of the linkage block 5. A clamping block 7 is fixedly connected to the bottom of the clamping rod 6. An anti-deviating mechanism is provided on the top of the L-shaped support block 4, and an adjustment mechanism is provided on one side of the L-shaped support block 4.

[0028] The anti-deviance mechanism includes a threaded rod 8 threadedly connected to the top of the L-shaped support block 4. The top of the L-shaped support block 4 is provided with a threaded hole 9 for use with the threaded rod 8. The top of the threaded rod 8 is fixedly connected with a twisting block 10. The bottom of the threaded rod 8 is provided with a bearing 11, and is rotatably connected to the top of the linkage block 5 through the bearing 11.

[0029] The present embodiment takes into account that the film in the prior art is generally punched by a punching machine 2, and the film is generally supported manually during the punching process, and the position of the film is easily deviated, thereby affecting the accuracy of the punching. Therefore, an anti-deviating mechanism is provided, which can drive the threaded rod 8 to rotate in the threaded hole 9 by rotating the twisting block 10, and the threaded rod 8 will gradually move upward, and at the same time drive the bearing 11 and the linkage block 5 to move upward along the trajectory of the sliding block 19 and the sliding groove 20, and the linkage block 5 will drive the pressing rod 6 and the pressing block 7 to move upward. Then, the film is placed on the base 1 from one side, and the twisting block 10 is rotated in the opposite direction. The twisting block 10 will drive the threaded rod 8 to gradually move downward under the restriction of the threaded hole 9, and at the same time drive the bearing 11 and the linkage block 5 to move downward, and the linkage block 5 will drive the pressing rod 6 and the pressing block 7 to move downward, so that the protective pad 21 at the bottom of the pressing block 7 is in close contact with the film surface, which can effectively press the film and prevent the film position from deviating.

[0030] The invention solves the problem that, considering that the film in the prior art is generally punched by a punching machine 2 and the film is generally supported manually during the punching process, the position of the film is easily offset, thereby affecting the punching accuracy.

[0031] Preferably, a sliding block 19 is fixedly connected to one side of the linkage block 5 , and a sliding groove 20 for use with the sliding block 19 is formed on the inner wall of the L-shaped support block 4 .

[0032] In this embodiment, by providing the sliding block 19 and the sliding groove 20, the movement trajectory of the linkage block 5 and other structures can be restricted so that they can only move vertically along the sliding block 19 and the sliding groove 20, thereby playing a role in restricting the movement trajectory.

[0033] Preferably, a protective pad 21 is fixedly connected to the bottom of the pressing block 7, and the material of the protective pad 21 is rubber.

[0034] In this embodiment, the protective pad 21 is provided to prevent the pressing block 7 from directly affecting the contact with the film and causing wear on the film surface. The rubber material characteristics of the protective pad 21 can protect the film.

[0035] Preferably, a twisting groove 22 is symmetrically formed on the circumferential side of the twisting block 10 , and the twisting groove 22 is arc-shaped.

[0036] In this embodiment, the twisting groove 22 is provided to improve the leverage point for grasping when the twisting block 10 needs to be rotated, thereby facilitating the rotation of the twisting block 10 . Example 2:

[0037] On the basis of Example 1, the anti-deviation mechanism in this embodiment can prevent the film position from being shifted by pressing the film, thereby improving the accuracy of punching. However, considering the different widths of the film, if the anti-deviation mechanism cannot be accurately pressed on the film surface, the position of the film will still be shifted during punching, affecting the accuracy of punching. The adjustment mechanism in this application includes a shell 12 fixedly connected to one side of the L-shaped support block 4, a movable block 13 is provided inside the shell 12, a positioning rod 14 is provided at the bottom of the movable block 13, the bottom of the positioning rod 14 passes through the bottom of the shell 12, and a positioning hole 15 is provided at the top of the base 1 for use with the positioning rod 14. The top of the movable block 13 is fixedly connected to a traction rod 16, the top of the traction rod 16 passes through the top of the shell 12, and is fixedly connected to a traction block 17.

[0038] In this embodiment, the different widths of films are taken into consideration. If the anti-deviation mechanism cannot be accurately pressed against the film surface, the position of the film will still be deviated when punching, affecting the accuracy of the punching. Therefore, by providing an adjustment mechanism, the traction block 17 can be pushed upward, and the traction block 17 drives the traction rod 16 to move upward. The traction rod 16 drives the movable block 13 and the positioning rod 14 to move upward, so that the positioning rod 14 leaves the positioning hole 15. After that, the position of the L-shaped support block 4 can be adjusted along the trajectory of the dovetail slide rail 3 according to the width of the film. After reaching the appropriate position, the traction block 17 is released, and the elastic force generated by the spring 18 will push the movable block 13 and the positioning rod 14 to move downward, so that the positioning rod 14 enters the corresponding positioning hole 15, completing the adjustment of the L-shaped support block 4, thereby achieving the effect of adjusting the pressing position of the anti-deviation mechanism, so that it can be accurately pressed against the film surface to prevent the film from deviating when punching.

[0039] A spring 18 is sleeved on the surface of the traction rod 16 . The top of the spring 18 is fixedly connected to the inner wall of the housing 12 , and the bottom of the spring 18 is fixedly connected to the top of the movable block 13 .

[0040] In this embodiment, the spring 18 is provided so that when the traction block 17 is released, the elastic force generated by the spring 18 pushes the movable block 13 and the positioning rod 14 downward, thereby achieving a reset effect.

[0041] Preferably, there are a plurality of positioning holes 15 , which are evenly distributed on the top of the base 1 .

[0042] In this embodiment, by providing a plurality of positioning holes 15 , after the position of the L-shaped support block 4 is adjusted, the positioning rods 14 can be inserted into the corresponding positioning holes 15 to quickly position the L-shaped support block 4 .

[0043] Working principle: The user drives the threaded rod 8 to rotate in the threaded hole 9 by rotating the twisting block 10. The threaded rod 8 will gradually move upward, and at the same time drive the bearing 11 and the linkage block 5 to move upward along the trajectory of the sliding block 19 and the sliding groove 20. The linkage block 5 will drive the clamping rod 6 and the clamping block 7 to move upward. Then, the film is placed on the base 1 from one side, and the twisting block 10 is rotated in the opposite direction. The twisting block 10 will drive the threaded rod 8 to gradually move downward under the restriction of the threaded hole 9, and at the same time drive the bearing 11 and the linkage block 5 to move downward. The linkage block 5 will drive the clamping rod 6 and the clamping block 7 to move downward, so that the protective pad 21 at the bottom of the clamping block 7 is in close contact with the surface of the film, which can effectively compress the film and prevent the film position from shifting.

[0044] Alternatively, the traction block 17 can be pushed upward, and the traction block 17 drives the traction rod 16 to move upward, and the traction rod 16 drives the movable block 13 and the positioning rod 14 to move upward, so that the positioning rod 14 leaves the positioning hole 15. After that, the position of the L-shaped support block 4 can be adjusted along the trajectory of the dovetail slide rail 3 according to the width of the film. After reaching the appropriate position, the traction block 17 is released, and the elastic force generated by the spring 18 will push the movable block 13 and the positioning rod 14 to move downward, so that the positioning rod 14 enters the corresponding positioning hole 15, completing the adjustment of the L-shaped support block 4, and then achieving the effect of adjusting the clamping position of the anti-deviation mechanism, so that it can be accurately pressed on the film surface to prevent the film from deviating during punching.

[0045] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
