[0002] In the paper-cutting industry, traditional paper cutting methods have many drawbacks. Manual cutting is not only inefficient, but also difficult to ensure cutting accuracy and consistency. It is prone to dimensional deviation and uneven cutting, which affects the quality of paper-cut works. At the same time, penetration relies on manual operation, resulting in high labor intensity. Long working hours can easily lead to operator fatigue, which will reduce work efficiency. In the prior art, there is a cutting device for traditional artistic paper-cutting, such as the Chinese patent number CN221716996U, which includes: a cutting plate, a limiting plate and a cutting strip. The left end of the cutting plate is fixedly installed with a mounting slot, the inner end of the mounting slot is snap-fitted with a receiving block, the upper end of the receiving block is fixedly installed with a snap-fit column, and the lower end of the receiving block is fixedly installed with a metal spring; the limiting plate is snap-fitted to the upper end of the cutting plate, and the upper and lower ends of the limiting plate are fixedly installed with a snap-fit strip; the inner end of the cutting strip is provided with a limiting hole, the snap-fit column is snap-fitted to the inner end of the limiting hole, the inner end of the cutting strip is provided with a cutting slot, and the inner end of the cutting slot is snap-fitted with a blade.

The telescopic rod 326 and the compression spring 327 cooperate to ensure the stability of the push while being compressed under extrusion. At this time, the one-way pushing device 325 rolls on the paper.

[0019] The adjusting device 33 includes a connecting frame 331, and the two sides of the connecting frame 331 are fixedly connected to the limiting frame 332. The outer wall of the top of the connecting frame 331 is fixedly connected to the positioning ring 333, and the inner wall of the positioning ring 333 is rotatably connected to the screw 334. The wall of the connecting frame 331 is symmetrically provided with a limiting groove 335. The inner wall of the connecting frame 331 is slidably connected to the outer wall of the sliding block 324 through the limiting groove 335. The outer wall of the bottom of the connecting frame 331 is fixedly connected to the outer wall of the top of the pushing plate 322, the outer wall of the limiting frame 332 is slidably connected to the inner wall of the fixed frame 1, the outer wall of the screw 334 is threadedly connected to the inner wall of the internal threaded tube 7, the outer wall of the connecting frame 331 is fixedly connected to the outer wall of the telescopic rod 326, and the outer wall of the connecting frame 331 is connected to the compression spring 327. The outer wall is fixedly connected, and the pawl 3255 of the one-way pushing device 325 cooperates with the ratchet 3252 under the action of the torsion spring 3256. The ratchet 3252 is fixed to the tripod 323 through the fixing rod 3251. The rotating roller 3254 rolls unidirectionally on the paper. When the cylinder 321 is pushed to the longest distance and then retracts, the previously compressed compression spring 327 rebounds due to the elastic force generated by the extrusion, thereby pushing the one-way pushing device 325 to move in the opposite direction. At this time, the pawl 3255 on the rotating roller 3254 will cooperate with the limiting effect of the positioning protrusion 3257 to be stuck in the position of the ratchet 3252, thereby preventing the rotating roller 3254 and the protective cover 3253 from rotating in the opposite direction. At this time, the rotating roller 3254 will push the paper to the cutting plate position 6 through friction to wait for cutting.

[0020] The paper storage device 4 includes a bottom plate 41, the outer wall of the bottom plate 41 is fixedly connected to a limit frame 42, the outer wall of the bottom of the bottom plate 41 is fixedly connected to a damping rod 43, the outer wall of the damping rod 43 is sleeved with a return spring 44, the outer wall of the top of the damping rod 43 is fixedly connected to a support plate 45, the inner wall of the support plate 45 is slidably connected to the limit rod 46, the outer wall of the bottom of the limit rod 46 is fixedly connected to the outer wall of the top of the bottom plate 41, the side wall of the limit frame 42 is slidably connected to the side wall of the support plate 45, and one end of the return spring 44 is fixedly connected to the outer wall of the bottom of the support plate 45. The other end of the return spring 44 is fixedly connected to the outer wall of the top of the bottom plate 41, and the outer wall of the top of the bottom plate 41 is fixedly connected to the outer wall of the bottom of the fixed frame 1. The paper is placed on the support plate 45. Due to the action of gravity, the paper gradually presses down the damping rod 43 and compresses the return spring 44, so that the support plate 45 gradually approaches the bottom plate 41. At this time, the squeezed return spring 44 provides supporting force, and the damping rod 43 ensures that the support plate 45 moves smoothly. A limit rod 46 is set to limit the support plate 45, so that the support plate 45 is difficult to deflect during the movement.

[0021] When the paper cutting device is working, the screw 334 of the adjusting device 33 rotates in the internal threaded tube 7. Since the limiting frame 332 slides on the inner wall of the fixed frame 1 to limit the position, and the screw 334 is relatively fixed to the connecting frame 331 through the positioning ring 333 and keeps rotating, the connecting frame 331 can move along the axial direction of the internal threaded tube 7 under the limiting action of the limiting frame 332. At this time, the connecting frame 331 is set to move upward to drive the reciprocating device 32 to rise, which provides convenience for subsequent paper placement. At the same time, the height can be adjusted according to the thickness of the paper, thereby increasing the applicability of the cutting device. The paper storage device 4 is used to store paper for paper cutting. The paper is placed on the support plate 45. Due to the effect of gravity, the paper gradually presses down the damping rod 43 and compresses the return spring 44, so that the support plate 45 gradually approaches the bottom plate 41. At this time, the compressed return spring 44 provides support force, and the damping rod 43 ensures that the support plate 45 moves smoothly. A limit rod 46 is provided to limit the support plate 45, making it difficult for the support plate 45 to deflect during movement. After the paper is placed, the connecting frame 331 is controlled to descend until the one-way pushing device 325 contacts the paper. The cylinder 321 on the fixed plate 31 is activated, and the end of the pneumatic part inside it pushes the pushing plate 322 to move. The sliding block 324 slides in the limiting groove 335 of the connecting frame 331. The telescopic rod 326 and the compression spring 327 cooperate to ensure the smooth pushing and compress under the squeeze. At this time, the one-way pushing device 325 rolls on the paper and cooperates with the limiting frame 42 to prevent the paper from deflecting under the outward push of the one-way pushing device 325. The pawl 3255 of the one-way pushing device 325 cooperates with the ratchet 3252 under the action of the torsion spring 3256. The ratchet 3252 is fixed to the tripod 323 through the fixing rod 3251. The rotating roller 3254 rolls unidirectionally on the paper. When the cylinder 321 pushes to the maximum distance and then retracts, the previously compressed compression spring 327 rebounds due to the elastic force generated by the squeezing, thereby pushing the one-way pushing device 325 to move in the opposite direction. At this time, the pawl 3255 on the rotating roller 3254 will cooperate with the limiting action of the positioning protrusion 3257 to be stuck in the position of the ratchet 3252, thereby preventing the rotating roller 3254 and the protective cover 3253 from rotating in the opposite direction. At this time, the rotating roller 3254 will push the paper to the cutting plate position 6 through friction to wait for cutting. At this time, the servo motor 22 on the bracket 21 starts, driving the rotating rod 23 and the eccentric disk 24 to rotate. The eccentric disk 24 drives the connecting block 26 to swing through the rotating block 25. The fixed shaft 28 slides within the limit block 29 to ensure the vertical movement of the cutting knife 27, causing the cutting knife 27 to move up and down to cut. The paper is pushed onto the cutting plate 6 by the paper feeding device 3, cut by the cutting knife 27, and then sent out from the discharge plate 5. The paper feeding device 3 can realize unidirectional stable pushing of paper and can adjust the paper feeding position. The cutting device 2 can accurately cut the paper. The paper storage device 4 can store the paper in an orderly manner and ensure smooth paper feeding. The coordinated work of each device improves the efficiency and accuracy of paper cutting and reduces the intensity of manual labor.
