Technical Field

[0001] This utility model relates to the technical field of protective film processing equipment, specifically a protective film dotting machine with adjustable dot hole positions. Background Technology

[0002] In the production process of protective film, it is often necessary to process holes in specific positions and arrangements on the film to meet different usage requirements, such as air permeability, water permeability, and positioning functions. Protective film is perforated using a dotting machine, which includes a frame, protective film unwinding equipment, protective film rewinding equipment, guide rollers, traction rollers, and perforation components. Existing protective film dotting machines have certain limitations in adjusting the perforation position, often only able to perform relatively fixed perforation patterns, making it difficult to flexibly adapt to diverse perforation position requirements.

[0003] To address the aforementioned issues, there is an urgent need for innovative design based on the existing spot-line machine. Utility Model Content

[0004] The purpose of this invention is to provide a protective film dotting machine with adjustable dot position to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective film dotting machine with adjustable dotting position, comprising a frame and a movable plate. A first cylinder is fixed at the top of the frame, and a horizontal plate is fixed at the lower end of the first cylinder. A rectangular block and a fixed block are fixed at the two ends of the bottom of the horizontal plate, respectively. Another rectangular block is attached to the bottom of the horizontal plate near the fixed block. A second cylinder is fixed to one side of the fixed block, and the end of the second cylinder is fixedly connected to one side of the other rectangular block. A groove is provided on one side of each of the two rectangular blocks. A first rotating shaft is rotatably installed inside the groove. The middle parts of two movable plates distributed vertically are rotatably connected by a positioning pin. The connection between two adjacent movable plates is rotatably connected by a second rotating shaft. The inner side of the end of the upper movable plate is fixedly connected to the outer wall of the first rotating shaft. Limiting rods are fixed on the upper and lower surfaces of the end of the lower movable plate. The ends of the limiting rods are located inside the limiting grooves, which are opened at the bottom and top of the grooves. A fixed plate is fixed at the center of the bottom of the lower movable plate, and a punching needle is fixed at the center of the bottom of the fixed plate.

[0006] Preferably, the two movable plates distributed vertically form an "X" shape, and the positioning pin is designed as an "I" shape.

[0007] Preferably, two adjacent movable plates form a "V" shape.

[0008] Preferably, the end of the limiting rod and the limiting groove form a sliding structure.

[0009] Preferably, the fixing plate is designed as a "U" shaped structure, the central axes of the fixing plate, the punching pin and the positioning pin coincide with each other, and the fixing plate, the punching pin and the positioning pin are all distributed at equal intervals below the horizontal plate.

[0010] Preferably, there are two first cylinders, which are symmetrically distributed about the central axis of the horizontal plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the protective film dotting machine with adjustable dotting position can simultaneously increase or decrease the distance between adjacent dotting needles by activating the extension and retraction of the second cylinder, without the need to adjust the position of each dotting needle individually, thus improving work efficiency, solving the problem that the distance between dotting needles on existing protective film dotting machines cannot be adjusted, and improving the versatility of the protective film dotting machine.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: a protective film dotting machine with adjustable dot position, including a frame 1 and a movable plate 9. A first cylinder 2 is fixed at the top of the frame 1, and a horizontal plate 3 is fixed at the lower end of the first cylinder 2. Rectangular blocks 4 and fixed blocks 5 are fixed at the two ends of the bottom of the horizontal plate 3, respectively. Another rectangular block 4 is attached to the bottom of the horizontal plate 3 near the fixed block 5. A second cylinder 6 is fixed to one side of the fixed block 5, and the end of the second cylinder 6 is fixedly connected to one side of the other rectangular block 4. A groove 7 is opened on one side of each of the two rectangular blocks 4. A first rotating shaft 8 is rotatably installed inside the groove 7. The middle of the two vertically distributed movable plates 9 is rotatably connected by a positioning pin 10. The connection of two adjacent movable plates 9 is rotatably connected by a second rotating shaft 13. The two vertically distributed movable plates 9 form an "X" shape structure. The positioning pin 10 is designed as an "I" shape structure. The two adjacent movable plates 9 form a "V" shape structure. The inner side of the upper movable plate 9 is fixedly connected to the outer wall of the first rotating shaft 8. The upper and lower surfaces of the lower movable plate 9 are fixed with limit rods 11. The end of the limit rod 11 is located inside the limit groove 12. The limit groove 12 is opened at the bottom and top of the groove 7, ensuring that when the two rectangular blocks 4 move closer to each other, the distance between the two adjacent positioning pins 10 will decrease, and when the two rectangular blocks 4 move away from each other, the distance between the two adjacent positioning pins 10 will increase. Thus, the distance between several positioning pins 10 can be adjusted at the same time. The end of the limit rod 11 and the limit groove 12 form a sliding structure. The design of the limit rod 11 and the limit groove 12 ensures that the ends of the two movable plates 9 distributed above and below can be on the same straight line when they move away from or closer to each other. A fixing plate 14 is fixed at the center of the bottom of the lower movable plate 9, and a punching pin 15 is fixed at the center of the bottom of the fixing plate 14.

[0019] The fixing plate 14 is designed with a "U" shape. The central axes of the fixing plate 14, the punch pin 15 and the positioning pin 10 coincide with each other. The fixing plate 14, the punch pin 15 and the positioning pin 10 are all distributed at equal intervals below the horizontal plate 3, which ensures that when the positioning pins 10 move away from each other or move closer to each other, the punch pins 15 can also move away from each other or move closer to each other.

[0020] There are two first cylinders 2, which are symmetrically distributed about the central axis of the horizontal plate 3, which is beneficial for the vertical movement of the horizontal plate 3.

[0021] Working principle: First, the protective film roll is installed on the unwinding device of the dotting machine. Then, one end of the protective film is pulled so that it is installed on the guide roller and traction roller, and the protective film is positioned below the perforation needles 15. Finally, one end of the protective film is fixed on the winding device of the dotting machine. Then, the winding device is started to wind up the protective film, and the unwinding device unwinds the protective film, causing the protective film to move. Then, the first cylinder 2 is started, which drives the horizontal plate 3 and several perforation needles 15 to move downward. At this time, the protective film does not move, and the several perforation needles 15 complete the perforation of the protective film. Then, the first cylinder 2 is started, which causes the several perforation needles 15 to move upward and reset. Then, the unwinding device and the winding device are started again, causing the protective film to move a certain distance. Then, the first cylinder 2 is started again to perforate the protective film. The above operation is repeated to complete the perforation operation of the protective film. The above operation is existing technology and will not be described in detail here.

[0022] When it is necessary to reduce the distance between two punching pins 15, the second cylinder 6 is activated. The second cylinder 6 pushes the rectangular block 4, reducing the distance between the two rectangular blocks 4. At the same time, the upper movable plate 9 rotates around the central axis of the first rotating shaft 8, and the lower movable plate 9 drives the limiting rod 11 to move inside the limiting groove 12, causing the limiting rod 11 and the first rotating shaft 8 to move away from each other. The two upper and lower movable plates 9 rotate around the positioning pin 10, increasing the included angle between the two upper and lower movable plates 9. The two adjacent movable plates 9 rotate around the second rotating shaft 13, decreasing the included angle between the two adjacent movable plates 9. The two positioning pins 10 move closer to each other, causing the adjacent fixed plates 14 to move closer to each other, and causing the adjacent punching pins 15 to move closer to each other. Similarly, when the second cylinder 6 is activated, increasing the distance between the two rectangular blocks 4, the adjacent punching pins 15 move away from each other, thus completing the simultaneous adjustment of the distance between several punching pins 15, improving work efficiency.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
