[0002] After printing, paper books need to be bound into books. In order to ensure the neatness of the edges of the books and improve the appearance of the books and the user experience, the edges of the books usually need to be trimmed by a paper cutting machine.

[0004] In the related technology described above, when performing the paper cutting operation, the book to be cut is first placed on the workbench, then the position of the book is adjusted so that the edge to be trimmed corresponds to the position of the paper cutting knife, and then the hydraulic pump drives the paper cutting knife to move towards the blade slot side until the edge of the book is cut, and then the other side of the book is exchanged for cutting. In order to avoid the influence of the cut-off waste edge on the cutting effect, the operator needs to manually approach the paper cutting knife and take out the cut-off waste edge of the book, which has a high safety risk in the operation process.

[0071] With reference to Figure 6 and Figure 8 , the vertical section of the locking rod 72 can pass through the locking hole 711 from top to bottom to realize the position fixation of the locking sheet 71, in order to maintain the stability of the locking, the limiting unit 7 further comprises a tension spring 73, the tension spring 73 is arranged vertically, one end of the tension spring 73 is welded and fixed with the bottom wall of the sliding slot 33, the other end is welded and fixed with the bottom wall of the locking rod 72, and the frame 1 is provided with a boss 14 extending out, when the paper cutter 3 is cut and extends into the accommodation slot 21, the extending section of the locking rod 72 abuts against the top wall of the boss 14, and the locking rod 72 makes the vertical section thereof out of the locking hole 711 by overcoming the elastic force of the tension spring 73.

[0072] With reference to Figure 9 , in order to maintain the cleanliness of the placing table 2 and realize the storage of the waste edge, the placing table 2 is sunken to form a waste storage groove 22, and the waste strip 4 is driven by the pushing spring 62 to move towards the side away from the paper cutter 3 and push the waste edge into the waste storage groove 22.

The push rod 93 extends into the lower part of the placing table 2 through the gap slot 21. A small hole is formed in the push rod 93. The pulling rope 92 passes through the small hole to avoid disengagement of the pulling rope 92 and the push rod 93.

[0076] The implementation principle of the hydraulic paper cutting machine in the embodiment 1 is as follows: books are stacked on the placing table 2, and then the position of the books is adjusted so that the to-be-cut edge of the books is aligned with the projection position of the paper cutting knife 3.

[0084] Then the books are pressed, the hydraulic unit 12 applies force to the paper cutting knife 3, so that the paper cutting knife 3 moves towards one side of the accommodation slot 21, and the paper cutting knife 3 moves downward while driving the reset rod 5 to move through the push-out unit 6, the push-out section always has a tendency to abut against the abutment shaft 111 in the direction of the guide rod 61 under the action of the push-out spring 62, and since the vertical section of the locking rod 72 passes through the locking hole 711 at this time, the connecting section 51 is still locked through the locking piece 71, so the position of the push-off bar 4 does not change.

[0085] Until the paper cutting knife 3 is cut and extends into the accommodation slot 21, at this time the locking rod 72 is in contact with the rack 1, the locking rod 72 overcomes the elastic force of the tension spring 73 to make the vertical section of the locking rod 72 disengage from the locking hole 711 from bottom to top, the connecting section 51 is released, the push-out spring 62 applies force to the connecting section 51 through the outward expansion section 52, and drives the push-off bar 4 to move away from the paper cutting knife 3 through the connecting section 51, and the push-off bar 4 is in sliding connection with the top wall of the placing table 2 at the same time, to push the waste edge generated by cutting away from the paper cutting knife 3.

[0086] At the same time, the movement of the paper cutting knife 3 drives the driving bar 94 to move, the driving bar 94 is in rolling connection with the friction wheel 95 to make the friction wheel 95 rotate, the friction wheel 95 rotates while being in rolling connection with the driven bar 96, and then drives the closing plate 8 to overcome the elastic force of the reset spring 91 through the driven bar 96 to realize the opening of the upper end of the waste containing groove 22, and the push-off bar 4 pushes the waste edge into the waste containing groove 22.

[0087] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
