The hydraulic rod 5 is installed on the bottom inner wall of the machine base 1, and its pushing end can slide along the inner wall of the fixed block 3 to provide a power source to drive the movement of the pushing block 6, thereby controlling the clamping action of the clamping block 8.

[0033] The outer wall of the clamping block 8 is slidably connected to the inner wall of the chute 4. The bottom inner wall of the machine base 1 is fixedly connected with a hydraulic rod 5, and the pushing end of the hydraulic rod 5 is fixedly connected with a pushing block 6. The pushing block 6 is fixedly connected to the pushing end of the hydraulic rod 5, and its left and right sides are linked with the clamping block 8 through rotatably connected square rods 7 to ensure the accurate positioning of the clamping block 8 and the uniform distribution of the clamping force.

The outer wall of the clamping block 14 is fixedly connected with a tension spring 15. The clamping block 14 is in contact with the outer wall of the cutting knife 10. Through the elastic action of the clamping block 14, the impact during the downward pressing process of the cutting knife 10 is further reduced.

[0035] The outer wall of the clamping block 14 is fixedly connected with a tension spring 15. The tension spring 15 is fixed on the outer wall of the clamping block 14 and acts together with the clamping block 14 to absorb the impact force through elastic deformation and protect the equipment.

[0036] Working principle: Start the hydraulic rod 5. The pushing end pulls the pushing block 6. The pushing block 6 is linked through the square rod 7 connected by rotation, and the power is transmitted to the clamping block 8. Under the guidance of the chute 4, the clamping block 8 slides smoothly along the inner wall of the square opening 2 to accurately clamp the corrugated cardboard to be die-cut. This process requires no manual intervention, realizing automatic clamping and alignment, reducing the downtime and manual adjustment, and significantly improving the production efficiency. The precise sliding and positioning of the clamping block 8 ensure the position accuracy of the corrugated cardboard during the die-cutting process, thus improving the die-cutting accuracy. The stability of the clamping and alignment reduces the product size error caused by position deviation, ensures the consistency of the product size, and meets the high-quality production requirements. The automatic feature of the clamping and alignment avoids the cumbersome steps of manual adjustment, reduces the waiting time during the production process, makes the entire die-cutting process smoother, and significantly improves the production efficiency. At the same time, it reduces the error of manual operation and improves the product quality. The high precision of the clamping and alignment makes it unnecessary to perform additional adjustment and correction work during the die-cutting process, reduces the production interruption caused by adjustment, ensures the continuity of the production process, and reduces the production cost.

[0037] When the cutting knife 10 descends during the die-cutting process, the decompression spring 13 begins to contract, and this process reduces the impact force when the cutting knife 10 contacts the top of the decompression plate 19. At the same time, the cutting knife 10 contacts the clamping block 14, further causing the tension spring 15 and the spring 17 to start compressing. The entire buffer system works together to effectively absorb and disperse the impact force generated when the cutting knife 10 presses down. The buffering effect also indirectly improves the die-cutting quality. Since the stability of the cutting knife 10 during die-cutting increases, the die-cutting process is smoother, reducing the phenomenon of uneven die-cutting caused by impact and ensuring the consistency and accuracy of the product.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
