Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag processing, in particular to a punching device used for plastic bag processing. Background Art

[0002] Plastic bags are commonly used for packaging and storage, typically made of plastic. Punching devices are used during plastic bag processing to create tiny holes in the bags, increasing their breathability. This prevents food spoilage due to lack of air permeability, while also keeping packaged products fresh in environments where air permeability is critical. Furthermore, by creating these holes, the punching device reduces the pressure difference between the inside and outside of the bag, reducing the risk of rupture at high altitudes or in high temperatures.

[0003] When using an existing punching device for plastic bag processing, the waste collection drawer is opened, and the handle is pulled to drive the sliding connecting rod and the scraper. The scraper scrapes the waste at the bottom of the workbench and allows it to enter the waste collection drawer, so that the waste can be collected, ensuring a clean working environment and allowing the waste to be recycled.

[0004] However, when using this method, plastic bags of different sizes cannot be compressed and fixed. If the punching device cannot provide appropriate fixing and pressing force, the plastic bag will move or shake during the punching operation, resulting in an unstable operating environment, causing inaccurate or inconsistent punching positions, affecting the quality and accuracy of the punching. The device cannot accurately meet the requirements of each bag, and the punching may fail or the hole position may deviate from the expectation, resulting in poor punching effect or damage to the bag, increasing the risk of punching failure and waste.

[0007] Furthermore, the upper part of the operating panel is fixedly connected to a support frame, one side of the support frame is fixedly connected to a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a push block, both sides of the upper part of the push block are fixedly connected to a limiting assembly, the upper part of the push block is fixedly connected to a cylinder, and the output end of the cylinder is fixedly connected to a punch.

[0008] Furthermore, the limiting assembly includes a limiting plate, which is fixedly connected to both sides of the upper part of the push block and is slidably connected to the outside of the limiting rod.

[0009] Furthermore, both sides of the upper portion of the support frame are fixedly connected with vertical plates, and opposite sides of the two vertical plates are fixedly connected with limiting rods.

[0010] Furthermore, both inner sides of the operating table are fixedly connected with sliding rods, and both outer sides of the sliding rods are slidably connected with sliders.

[0011] Furthermore, the upper portion of the sliding block is fixedly connected to a second fixing frame, and the interior of the second fixing frame is slidably connected to a pull rod.

The inner sides of the operating platform 2 are fixedly connected with sliding rods 17, and the outer sides of the sliding rod 17 are slidably connected with sliders 18. The upper part of the slider 18 is fixedly connected with a fixed frame 2 19, and the inner part of the fixed frame 2 19 is slidably connected with a pull rod 22. One end of the pull rod 22 is fixedly connected to the movable plate 20, and the other end of the pull rod 22 is fixedly connected to the connecting plate 23. The outer part of the pull rod 22 is provided with a spring 21, one end of the spring 21 is fixedly connected to the inner part of the fixed frame 2 19, and the other end of the spring 21 is fixedly connected to the upper part of the movable plate 20.

[0025] Start the motor 12. When the motor 12 is started, its output end begins to drive the bidirectional screw rod 13 to rotate. As the bidirectional screw rod 13 rotates, the threaded sleeve 14 connected to it also begins to rotate. The rotation of the threaded sleeve 14 drives the movement of the fixed frame 15. The movement of the fixed frame 15 further drives the movement of the electric push rod 16 and the connecting plate 23. When the front connecting plate 23 moves, it will drive the positioning plate 24 to move. The movement of the positioning plate 24 also drives the movement of the rear connecting plate 23, further realizing the coordinated control of the entire clamping mechanism. As the rear connecting plate 23 moves, the fixed frame 2 19 and the slider 18 also start to move. The slider 18 slides on the outside of the slide rod 17. This sliding design makes the clamping process smoother and reduces the resistance caused by friction. Under the joint action of the threaded sleeve 14 and the slider 18, the two positioning plates The positioning plate 24 drives the pressing member 25 to move up and down for adjustment, so that the pressing member 25 can tightly fix the plastic bag.

The output end of the hydraulic cylinder 5 is fixedly connected to the push block 6. Both sides of the upper part of the push block 6 are fixedly connected to the limit assembly. The limit assembly includes a limit plate 7, which is fixedly connected to both sides of the upper part of the push block 6. The limit plate 7 is slidably connected to the outside of the limit rod 8. Both sides of the upper part of the support frame 4 are fixedly connected to the vertical plate 9, and the opposite sides of the two vertical plates 9 are fixedly connected to the limit rod 8. The upper part of the push block 6 is fixedly connected to the cylinder 10, and the output end of the cylinder 10 is fixedly connected to the punch 11.

[0027] Start the hydraulic cylinder 5, and the output end of the hydraulic cylinder 5 begins to push the push block 6 to move. As the push block 6 moves, it drives the limit plate 7 to slide outside the limit rod 8. This sliding is limited because the existence of the limit rod 8 ensures the movement trajectory and range of the limit plate 7, thereby ensuring the stability and reliability of the entire device. Under the action of the limit plate 7, the push block 6 further drives the cylinder 10 to move. In this process, the connection between the push block 6 and the cylinder 10 is tight, ensuring the synchronization of movement between the two. When the cylinder 10 moves to the appropriate position, start the cylinder 10, and the piston rod of the cylinder 10 starts to drive the punch 11 to punch.

[0028] Working principle: First, place the plastic bag on the upper part of the operating panel 3, start the motor 12, the output end of the motor 12 drives the bidirectional screw rod 13 to rotate, the rotation of the bidirectional screw rod 13 drives the threaded sleeve 14 to rotate, the rotation of the threaded sleeve 14 drives the fixed frame 15 to move, the movement of the fixed frame 15 drives the electric push rod 16 and the connecting plate 23 to move, the front connecting plate 23 moves to drive the positioning plate 24 to move, the positioning plate 24 moves to drive the rear connecting plate 23 to move, the rear connecting plate 23 moves to drive the fixed frame 2 19 and the slider 18 to move, so that the slider 18 slides on the outside of the slide rod 17, under the action of the threaded sleeve 14 and the slider 18, the two positioning plates 24 are close to each other, when the two positioning plates 24 are located on the upper part of the plastic bag, start the electric push rod 16, the output end of the electric push rod 16 pushes the connecting plate 23 to move, the connecting plate 23 drives the positioning plate 24 to move, when the positioning plate 24 moves, it drives the rear connecting plate 23 and the pull rod 22 When the bag is pressed down, the pull rod 22 drives the movable plate 20 to slide inside the fixed frame 21. When the movable plate 20 slides, the spring 21 is squeezed, so that the positioning plate 24 drives the pressing member 25 to move up and down for adjustment, so that the pressing member 25 presses and fixes the plastic bag, thereby effectively pressing and fixing plastic bags of different sizes, ensuring that the bag maintains a stable position during the punching process, which helps to accurately impact the holes and make the punching position accurate and consistent. Start the hydraulic cylinder 5, and the output end of the hydraulic cylinder 5 pushes the push block 6 to move. When the push block 6 moves, it drives the limit plate 7 to slide outside the limit rod 8.
