Description

Technical Field

[0001] The utility model relates to the technical field of polymer film processing, in particular to a hole puncher for an easy-to-pull adhesive release film. Background Art

[0002] Easy-to-pull release film is an important material used to create patterns on concrete surfaces. It is usually made of rubber or similar materials and has good elasticity and viscosity. It can be used to attach to the mold surface before pouring concrete to ensure the pattern or texture on the concrete surface. Punching holes in the easy-to-pull release film is to ensure that the easy-to-pull release film adheres firmly to the mold surface, release bubbles, and evenly distribute the coating, thereby improving demoulding performance and ultimately ensuring the quality of the pattern or texture on the concrete surface.

[0003] After searching, the announcement number: CN219054631U discloses a puncher for easy-to-pull adhesive release film on an assembly line, including: a support frame, one side of the support frame is connected to a fixed plate and a supporting plate by using an adjustable punching position component, a cylinder is installed on the top of the fixed plate, the output end of the cylinder is connected to a knife holder, the bottom end of the knife holder is connected to a punching knife, and a through hole is opened in the middle of the supporting plate directly below the punching knife; a protective component. A circular groove and a ball are provided at the bottom of the perforation, and several balls are evenly distributed along the circumference of the circular groove. The side of the circular groove close to the center of the perforation is flush with the inner wall of the perforation. When the punching knife punches the film on the supporting plate, it passes through the film and enters the perforation and the circular groove. The ball in the circular groove contacts the outer wall of the punching knife, which reduces the friction between the punching knife and the protective component, thereby reducing the degree of wear on the punching knife and increasing the service life of the punching knife. The punching machine in this application cannot adjust the punching distance spacing as required, resulting in low punching efficiency. If manual adjustment is performed, it may cause injury by the punching needle, which is not conducive to the safety of the puncher. Utility Model Content

One end of the connecting pipe 10 is fixedly connected to the piston column 6. The outer wall of the piston column 6 is fixedly connected to the fixed block 21 and the bottom of the outer wall of the slider 14. A punching assembly is provided inside the piston column 6. The punching assembly includes a piston rod 7 and a punching needle 8. The top of the punching needle 8 is fixedly connected to the bottom of the piston rod 7, and the piston rod 7 is slidably connected to the inside of the piston column 6;

[0024] Specifically, the pressing plate 3 can not only support the punching mechanism, but also press the easy-to-pull adhesive release film, which is convenient for punching the easy-to-pull adhesive release film. There are electric slide bars 4 on both sides of the pressing plate 3, which can control the sliding of the slide plate 5 to punch multiple holes in the easy-to-pull adhesive release film, and the slide plate 5 is suspended between the electric slide bars 4, which is convenient for the extension of the punching needle 8. On the slide plate 5, the air pump 12 is connected to the piston column 6 through the connecting tube 10 to adapt to the movement changes of the piston column 6, and it is convenient for the air pump 12 to control multiple piston columns 6 at the same time. By deflating the piston column 6 through the connecting tube 10, the piston rod 7 can be extended, and then By evacuating the piston column 6 through the connecting pipe 10, the piston rod 7 can be retracted, and the piston rod 7 is connected to the punching needle 8 to realize the punching of the easy-to-pull adhesive release film by the punching needle 8. The piston column 6 is installed on the fixed block 21 and the slider 14. The fixed block 21 and the slider 14 are both connected through the gallows 15. Under the action of the gallows 15, the slider 14 can be controlled to slide on the slide rail 11. When the gallows 15 is expanded, the slider 14 can be pushed out. When the gallows 15 is retracted, the slider 14 can be retracted. Similarly, by controlling one side slider 14 with an electric push rod 9, the gallows 15 can be retracted.

[0025] Reference Figure 4, one side of the pressing plate 3 is rotatably connected to the bottom plate 1, the top of the bottom plate 1 is fixedly connected to a sponge pad 16, the sponge pad 16 is arranged at the bottom of the pressing plate 3, one side of the top of the bottom plate 1 is fixedly connected to the support column 2, the support column 2 is arranged on one side of the pressing plate 3, one side of the top of the pressing plate 3 is rotatably connected to a rotating rod 13, the inside of the support column 2 is rotatably connected to a rotating block 18, the top of the rotating rod 13 is rotatably connected to a rotating rod 2 19, the inside of the rotating block 18 is fixedly connected to an electric push rod 2 17, one end of the rotating rod 2 19 is rotatably connected to one side of the outer wall of the support column 2, the output end of the electric push rod 2 17 is fixedly connected to a push block 20, and the outer wall of the rotating rod 2 19 is rotatably connected to the inside of the push block 20;

[0026] Specifically, a sponge pad 16 is provided on the top of the bottom plate 1, and the sponge pad 16 is used to place the easy-to-pull adhesive release film, which can not only prevent the damage of the easy-to-pull adhesive release film, but also facilitate the penetration of the punching needle 8, so that the punching needle 8 can completely penetrate the easy-to-pull adhesive release film, ensuring the integrity of the punching. At the same time, it can protect the punching needle 8 and increase the service life of the punching needle 8. The pressing plate 3 is connected to the rotating rod 13 on the rotating rod 2 19. The rotating rod 2 19 can be rotated to rotate on the bottom plate 1. The rotating rod 13 is convenient for coordinating with the changes in movement to achieve this effect. The rotation of the pressing plate 3 is convenient for inserting the easy-to-pull adhesive release film, preventing the punching needle 8 from scratching the easy-to-pull adhesive release film or scratching the staff. The rotating rod 2 19 is controlled to rotate by the electric push rod 2 17 and is connected by the push block 20 to adapt to the movement changes of the rotating rod 2 19 and the electric push rod 2 17. At the same time, the electric push rod 2 17 is rotated by the rotating block 18 to avoid movement interference.

[0027] Working principle: When punching holes, the push block 20 can be pulled by the electric push rod 2 17. Under the pulling of the push block 20, the rotating rod 2 19 will rotate, thereby driving the rotating rod 1 13. Then, through the cooperation of the rotating rod 13, the pressure plate 3 is pulled up and rotated open on the bottom plate 1. Then, the easy-to-pull adhesive release film can be placed on the sponge pad 16, and then the electric push rod 2 17 is controlled to push, so that the pressure plate 3 is pressed on the easy-to-pull adhesive release film, which is convenient for punching holes in the easy-to-pull adhesive release film. When punching holes, the air pump 12 pumps the piston rod 6 through the connecting pipe 10. The piston rod 7 is compressed and deflated to control the contraction of the piston column 6, thereby driving the punching needle 8 to punch holes. The piston column 6 is installed on the slider 14 and the fixed block 21. The slider 14 controls the spacing between them. The slider 14 is connected to the fixed block 21 through the gallows 15 and slides on the slide rail 11. Therefore, when the electric push rod 9 controls the slider 14 on one side to slide, under the action of the gallows 15, the sliders 14 on both sides will slide outward at the same time and maintain the same spacing to control the punching distance, and then the electric slide rod 4 is used to control the slide plate 5 to slide and punch holes.
