[0024] Specifically, each of the four corners of the base 10 is provided with a fixing block 1, which provides fixed support for the fixing block 1. The fixing block 1 provides fixed support for the hydraulic cylinder 2. The hydraulic cylinder 2 drives the first U-shaped block 3, which in turn drives the fixing rod 4 and the rotating piece 5 to move. The rotating piece 5 drives the connecting rod 6, which in turn drives the pressing plate 7 to position and fix the paper product. The pressing plate 7 rotates on the outer wall of the limiting rod 8, which in turn limits the pressing plate 7. The fixing block 1 provides fixed support for the support block 9, which in turn provides fixed support for the limiting rod 8. The pressing plates 7 at the four corners position and fix the paper product, ensuring that the paper product is stable during the cutting process and avoiding displacement or sliding. The base 10 provides support for the paper product.

[0025] Reference Figure 2 and Figure 4 A motor 12 is fixedly connected inside the support frame 11, and a rotating column 13 is fixedly installed at the output end of the motor 12. The outer wall of the rotating column 13 is rotatably connected to the inside of the support frame 11, and an eccentric block 14 is fixedly connected to the outer wall of the rotating column 13. A rotating plate 15 is rotatably connected to the outer wall of the eccentric block 14, and a connecting shaft 16 is rotatably connected inside the rotating plate 15. A second U-shaped block 17 is fixedly connected to the outer wall of the connecting shaft 16, and a cutting blade 18 is fixedly connected to the lower surface of the second U-shaped block 17.

[0026] Specifically, the support frame 11 provides fixed support for the motor 12, and the motor 12 drives the rotating column 13 to rotate inside the support frame 11. The support frame 11 provides auxiliary support and limit the rotation of the rotating column 13. Eccentric blocks 14 are provided on both sides of the rotating column 13. The rotating column 13 drives the eccentric blocks 14, which in turn drives the rotating plate 15 to move. The rotating plate 15 drives the connecting shaft 16, which in turn drives the second U-shaped block 17 to reciprocate. The second U-shaped block 17 drives the cutting blade 18 to cut the paper product.

[0027] Reference Figure 4 The outer wall of the cutting blade 18 is fixedly connected to a T-shaped slider 19, and the outer wall of the T-shaped slider 19 is slidably connected to the inside of the support frame 11; a limiting groove 20 is opened inside the support frame 11, and the outer wall of the T-shaped slider 19 is slidably connected to the inner wall of the limiting groove 20.

[0028] Specifically, the cutting blade 18 drives the T-shaped slider 19 to slide inside the support frame 11. A limiting groove 20 is opened inside the support frame 11, which then limits the T-shaped slider 19.

[0029] Working principle: When the device is needed, the paper product to be cut is placed on the upper surface of the base 10. The hydraulic cylinder 2 inside the fixing block 1 is activated. The hydraulic cylinder 2 drives the first U-shaped block 3, which in turn drives the fixing rod 4 and the rotating plate 5 to move. The rotating plate 5 drives the connecting rod 6, which in turn drives the pressing plate 7 to position and fix the paper product. At the same time, the pressing plate 7 rotates on the outer wall of the limiting rod 8, which limits the pressing plate 7 and ensures that the position of the paper product is stable during the cutting process, avoiding deviation or slippage, thereby improving the cutting accuracy and consistency.

[0030] Once the paper product is positioned and fixed, the motor 12 inside the support frame 11 is activated. The motor 12 drives the rotating column 13 to rotate inside the support frame 11. The rotating column 13 then drives the eccentric block 14, which in turn moves the rotating plate 15. The rotating plate 15 drives the connecting shaft 16, which in turn drives the second U-shaped block 17 to reciprocate. The second U-shaped block 17 drives the cutting blade 18, which in turn drives the T-shaped slider 19 to slide inside the support frame 11. The cutting blade 18 then cuts the paper product, achieving efficient and precise cutting, reducing human error, and improving production efficiency. This device not only ensures the stability of the paper product's position during the cutting process, avoiding offset or slippage, thereby improving cutting accuracy and consistency, increasing production efficiency, and reducing scrap rate, but also achieves efficient and precise cutting, reduces human error, and improves production efficiency. At the same time, it ensures a flat cut, improves product quality, and adapts to the needs of large-scale continuous processing.
