[0019] Reference Figures 1-3 A punching device for an automated bag-making machine, comprising:

[0020] Workbench 1, with a fixed bracket 4 fixedly installed at the top of the workbench 1. A hydraulic cylinder 5 is fixedly connected to the fixed bracket 4. A push rod 6 is fixedly connected to the output end of the hydraulic cylinder 5. The push rod 6 passes through the upper end face of the fixed bracket 4 and is fixedly connected to a punching blade 7. When the automatic bag making machine is installed together with the workbench 1, the packaging bags made by the bag making machine will automatically move to the workbench 1. The hydraulic cylinder 5 is started, and the hydraulic cylinder 5 pushes the push rod 6 to move up and down continuously, so that the punching blade 7 also moves up and down continuously to punch the packaging bag.

[0021] The storage structure includes a fixed groove 2 at the top of the workbench 1, a bearing plate 3 slidably connected to both sides of the fixed groove 2, a fixed through groove 8 on the side wall of the fixed bracket 4, a connecting bracket 9 fixedly installed on the push rod 6, the connecting bracket 9 passing through the corresponding fixed through groove 8 and fixedly connected to a fixed plate 10, a pressing block 11 fixedly installed on the fixed plate 10, and an adjustment structure installed on the bearing plate 3.

[0022] When the push rod 6 moves downward, the connecting bracket 9 fixedly installed on the push rod 6 moves accordingly, causing the fixed plate 10 to move together, so that the pressing block 11 fixedly connected to the fixed plate 10 also moves downward.

[0023] The adjustment structure includes a connecting plate 12 slidably connected to the side wall of the worktable 1, a mounting plate 14 fixedly connected to the connecting plate 12, a connecting rod 15 rotatably connected between the mounting plates 14, a connecting shaft 16 fixedly connected to the side wall of the bearing plate 3, the connecting shaft 16 rotatably connected to the connecting rod 15, a pushing block 13 corresponding to the extrusion block 11 fixedly connected to the top of the connecting plate 12, a sliding block fixedly connected to the side wall of the connecting plate 12, a sliding groove 17 corresponding to the sliding block opened on the worktable 1, and a fixing spring 18 fixedly connected between the sliding groove 17 and the sliding block; the connecting rod 15 is installed at an angle towards the worktable 1, the bottom end of the extrusion block 11 has a rounded corner, and the outer sides of both the extrusion block 11 and the pushing block 13 are fixedly wrapped with a protective layer to protect the extrusion block 11 and the pushing block 13;

[0024] As the fixed plate 10 moves, the pressing block 11 moves accordingly, causing the pressing block 11 to contact and press against the pushing block 13, pushing the pushing block 13 downward, causing the connecting plate 12 to move downward as well. The fixing spring 18 contracts, and at the same time, the mounting plate 14 fixedly installed on the connecting plate 12 moves downward together, pushing the end of the connecting rod 15 connected to the mounting plate 14 downward, causing the connecting rod 15 to rotate around its connection with the mounting plate 14, pushing the connecting shaft 16 and the bearing plate 3 to move away from the worktable 1, and finally causing the bearing plate 3 to move to the outside of the fixing groove 2, and the packaging bag on the bearing plate 3 falls off. When the punching knife 7 moves upward, the elastic force of the fixing spring 18 causes the connecting plate 12 to return to its original position.

[0025] A storage plate is slidably connected to the inner wall of the fixed groove 2 via a movable guide rail. A pull handle is fixedly installed on the storage plate. The packaging bags fall onto the storage plate and accumulate there. Pulling the pull handle pulls the storage plate outward to remove the packaging bags. A fixed cover plate is rotatably installed between the inner walls of the fixed groove 2 via a rotating shaft. The fixed cover plate is made of transparent material. Any transparent material is acceptable. Opening the fixed cover plate allows the punched packaging bags to be removed. The transparent material makes the amount of packaging bags inside the fixed cover plate visible, facilitating the removal of the packaging bags. The workbench 1 is equipped with a controller corresponding to the hydraulic cylinder 5. The controller and hydraulic cylinder 5 are existing technologies that are compatible. The controller can control the start and stop of the hydraulic cylinder 5.

[0026] In this invention, when the device is in use, the packaging bag of the bag-making machine moves onto the worktable 1, with both sides of the packaging bag positioned on the support plate 3. The hydraulic cylinder 5 is activated, pushing the push rod 6 up and down continuously, thereby causing the punching blade 7 to also move up and down continuously, punching the packaging bag. When the push rod 6 moves downwards, the connecting bracket 9 fixedly mounted on the push rod 6 moves accordingly, causing the fixed plate 10 to move as well. This causes the extrusion block 11, fixedly connected to the fixed plate 10, to also move downwards. As the fixed plate 10 moves, the extrusion block 11 moves accordingly, contacting and extruding with the push block 13, thus pushing the push block 13 downwards. This causes the connecting plate 12 to move downwards, the fixing spring 18 to contract, and the mounting plate 14 fixed on the connecting plate 12 to move downwards together. This pushes the end of the connecting rod 15 connected to the mounting plate 14 downwards, causing the connecting rod 15 to rotate around its connection point with the mounting plate 14. This pushes the connecting shaft 16 and the bearing plate 3 to move away from the worktable 1, eventually moving the bearing plate 3 to the outside of the fixing groove 2. The packaging bag on the bearing plate 3 falls off. When the punching blade 7 moves upwards, the elastic force of the fixing spring 18 causes the connecting plate 12 to return to its original position. The fixing cover is opened, the pull handle is pulled, and the storage plate is pulled outwards to remove the packaging bag.
