[0018] In this embodiment, the paper product to be punched is placed on the top of the table 1. The position of the paper product to be punched is determined and it is stably placed above the insertion hole 13. Then, the hydraulic lifting rod 81 inside the two side fixing frames 7 is activated. The hydraulic lifting rod 81 pulls down the top connecting plate 82, causing the pressure plate 83 to press down on the top of the paper product. Since the pressure plate 83 is U-shaped, it can press and fix the top of the paper product, so that the paper product remains stable during the punching process and ensures that most of the punched holes are aligned.

[0019] Example 2 like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support device 2 includes a support column 21, a first groove 22 is provided on the front side of the support column 21, a slide bar 23 is fixedly connected to one side of the support column 21, a limit plate 24 is provided below the slide bar 23, a support platform 25 is fixedly connected to the lower front side of the support column 21, a hydraulic telescopic rod 26 is fixedly connected to the top of the support platform 25, a first cutting cylinder 27 is fixedly connected to the top of the hydraulic telescopic rod 26, and a threaded rod 41 is fixedly connected to the output end of the first motor 4.

[0020] The threaded rod 41 is installed inside the first groove 22, and the first cutting cylinder 27 is inserted into the insertion hole 13 from the bottom of the card plate 12.

[0021] In this embodiment, the first motor 4 is started to adjust the height of the transition plate 6 along the height of the threaded rod 41. In order to maintain stability during the movement, one end of the transition plate 6 is engaged with the inside of the slide bar 23. The support column 21 is fixedly supported at the rear end of the first slot 11. Then, the limiting plate 24 stably supports the stability of the device installation, ensuring that the installation of the support column 21 will not slip. At the same time, a hydraulic telescopic rod 26 is installed on one side of the bottom of the support device 2 through the support platform 25. The hydraulic telescopic rod 26 drives the first cutting cylinder 27 to move up and down, performing secondary treatment on the top punched holes that are still sticky, and also pushing out the waste material dug out in the middle of the hole from below, making the device punch paper products cleaner.

[0022] Example 3 like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a second slot 61 is provided at the rear end of the transition plate 6, a support block 62 is fixedly connected to one end of the transition plate 6, a fixing cylinder 63 is fixedly installed at the bottom of the support block 62, a second motor 52 is fixedly inserted into the bottom of the fixing cylinder 63, and a second cutting cylinder 53 is movably connected to the output end of the second motor 52.

[0024] In this embodiment, to ensure the stability of the device during the punching of paper products, the top of the other end of the support plate 3 is fixedly connected to the cylinder 5. Activating the cylinder 5 causes the hydraulic rod 51 to pull the other end of the transition plate 6, so that both ends of the transition plate 6 can maintain balance, which facilitates the stability of the bottom second cutting cylinder 53. At the same time, the top of the second cutting cylinder 53 is movably connected to the motor output end, which allows the device to be disassembled and the second cutting cylinder 53 to be adjusted according to the size of the punching required by the device, making the device more convenient to use.

[0025] The working principle of this punching device for printing paper products will be explained in detail below.

Then, the hydraulic lifting rod 81 inside the two side fixing frames 7 is activated. The hydraulic lifting rod 81 pulls down the top connecting plate 82, causing the pressure plate 83 to press down on the top of the paper product. Since the pressure plate 83 is U-shaped, it can press and fix the top of the paper product, keeping the paper product stable during the punching process and ensuring that most of the punched holes are aligned. The first motor 4 is activated to adjust the height of the transition plate 6 along the height of the threaded rod 41. In order to maintain stability during the movement, one end of the transition plate 6 is engaged with the inside of the slide bar 23 on both sides. The support column 21 is supported and fixed at the rear end of the first slot 11. Then, the limiting plate 24 stably supports the stability of the device installation and ensures the support. The installation of column 21 will not cause it to slide down. At the same time, a hydraulic telescopic rod 26 is installed on one side of the bottom of the support device 2 via a support platform 25. The hydraulic telescopic rod 26 drives the first cutting cylinder 27 to move up and down, which performs secondary treatment on the holes with adhesion in the top punching, and can also push out the waste material dug out in the middle of the hole from below, making the device punch paper products cleaner and ensuring the stability of the device during the up and down punching of paper products. The other end of the support plate 3 is fixedly connected to the top of the cylinder 5. Activating the cylinder 5 causes the hydraulic rod 51 to connect and pull the other end of the transition plate 6, so that both ends of the transition plate 6 can maintain balance, which makes it easy for the bottom second cutting cylinder 53 to remain stable. At the same time, the top of the second cutting cylinder 53 is movably connected to the motor output end, which allows the device to be disassembled and the second cutting cylinder 53 to be adjusted according to the size of the punching required by the device, making the device more convenient to use.
