The telescopic end of the second hydraulic rod 8 is movably connected to the positioning plate 9. A sliding groove 27 is provided on the side wall of the positioning plate 9 near the punching plate 7. Two electric sliders 28 are slidably installed inside the sliding groove 27. The movable rod 10 is connected to the side of the electric slider 28 away from the positioning plate 9. The sliding of the electric slider 28 in the sliding groove 27 causes the movable rod 10 to move on the positioning plate 9 to a preset position. Then, the second hydraulic rod 8 extends downward until the bottom of the positioning plate 9 abuts against the top of the bag. At this time, the two movable rods 10 are located on both sides of the part of the bag that needs to be punched. This operation method can complete the squeezing and fixing of multiple bags, preventing the bags from shifting during the punching process and affecting the quality of the bag punching.

[0034] As a technical optimization of this utility model, the top of the positioning plate 9 has a third slot 23. A lead screw 24 is rotatably installed inside the third slot 23, and a sliding block 25 is slidably installed inside the third slot 23. The lead screw 24 is threaded through the sliding block 25, and the top of the sliding block 25 is connected to the telescopic end of the second hydraulic rod 8. A rotary motor 26 is installed on the side wall of the positioning plate 9 away from the movable rod 10. The output end of the rotary motor 26 movably passes through the end wall of the third slot 23 and is connected to the lead screw 24. By rotating the lead screw 24 driven by the rotary motor 26, the sliding block 25 can be driven to slide in the third slot 23, thereby enabling the positioning plate 9 to move according to usage requirements.

[0035] As a technical optimization of this utility model, the collection mechanism includes a collection box 2 and a flipping plate 3. The collection box 2 is installed at the bottom of the workbench 1. A first slot 12 is formed through the workbench 1 below the punching plate 7. The flipping plate 3 is installed inside the first slot 12. Electric rotating shafts 13 are embedded in the inner walls on both sides of one end of the first slot 12. The output end of the electric rotating shaft 13 is connected to the side wall of the flipping plate 3. The punched waste is located at the top of the flipping plate 3. Then, the electric rotating shaft 13 drives the flipping plate 3 to flip downwards, and the punched waste falls from the first slot 12 into the collection box 2 for collection.

[0036] In use, all electrical equipment in this device is powered by an external power source connected to a wire. The device controls the electrical equipment by setting up a control system. The punching knife used on the punching plate 7 in this device is a mature existing technology, so it will not be described in detail. There are multiple sizes of punching plate 7 used in this device, which are replaceable components. They are replaced according to the size of the punching bag required.

[0037] The bag to be punched is placed on top of the workbench 1, with the punching area located at the bottom of the punching plate 7. The electric slider 28 slides in the sliding groove 27, causing the movable rod 10 to move to the preset position on the positioning plate 9. Then, the second hydraulic rod 8 extends downward until the bottom of the positioning plate 9 abuts against the top of the bag. At this time, the two movable rods 10 are located on both sides of the punching area of ​​the bag. This operation method can complete the squeezing and fixing of multiple bags, preventing the bags from shifting during the punching process and affecting the quality of the bag punching.

[0038] Subsequently, by extending downwards via the first hydraulic rod 5, the punching plate 7 can be moved downwards. When the punching plate 7 moves downwards until the punching knife contacts the bag and continues to move downwards to the preset position, the punching of the bag is completed. The punched waste is located at the top of the flipping plate 3. Then, the electric rotating shaft 13 drives the flipping plate 3 to flip downwards, and the punched waste will fall from the first slot 12 into the inside of the collection box 2 for collection. During the downward flipping of the flipping plate 3, the electric telescopic rod 22 drives the lifting rod 21 to extend and retract downwards, which can push off the waste adsorbed at the bottom of the punching plate 7, preventing the waste from adsorbing at the bottom of the punching plate 7 and affecting the next punching.

[0039] When the punch plate 7 needs to be replaced, the second hydraulic rod 8 drives the positioning plate 9 to rise and fall, so that the top of the movable rod 10 rises and falls to the same level as the top of the punch plate 7. Then, the electric slider 28 slides in the sliding groove 27, causing the two movable rods 10 to move closer to each other and clamp on both sides of the punch plate 7. Then, the operator pulls the positioning pin 15 out of the plug rod 14, and then pulls the plug rod 14 out of the mounting plate 6. Then, the first hydraulic rod 5 remains stationary, and the second hydraulic rod 8 continues to extend downward. This method of operation allows the punch plate 7 to be removed without the need for manual contact with the punch plate 7, thus avoiding injury to workers during the disassembly process caused by the punching blades on the punch plate 7. By rotating the lead screw 24 driven by the rotary motor 26, the positioning plate 9 can be moved. Combined with the up-and-down movement of the positioning plate 9, the movable rod 10 can clamp the removed punch plate 7 and move it to the preset position. Then, the two movable rods 10 move away from each other, thus completing the lowering of the removed punch plate 7.

[0040] When a new size punch plate 7 needs to be installed, simply place the new punch plate 7 in the preset position, and then follow the above operation method to make the movable rod 10 clamp the punch plate 7 and move the punch plate 7 so that the connecting rod 16 on the new punch plate 7 is inserted into the insertion slot 18 on the mounting plate 6. Then, the operator will connect the insertion rod 14 and the positioning pin 15 according to... Figure 7 Once installed as shown, the installation of the new punch plate 7 is complete.

[0041] The positioning plate 9 and the movable rod 10 can move freely, allowing them to be adapted to use punched plates 7 of different sizes.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
