One side of the transmission block 305 is fixedly connected to the output shaft of a vibration motor 306. A gantry 401 is fixedly arranged on one side of the top of the base 1. The top of the inner wall of the gantry 401 is fixedly provided with a hydraulic cylinder 402. The telescopic end of the hydraulic cylinder 402 is fixedly provided with a mounting block 403. A groove is formed at the bottom of the mounting block 403, and a cutting knife 404 is movably arranged in the groove. Screw holes are formed in the front and rear parts on both sides of the mounting block 403, and bolts 405 are movably arranged in the screw holes. Chute grooves are formed in the front and rear parts on both sides of the cutting knife 404, and second return springs 406 are fixedly arranged in the chute grooves. One side of the second return spring 406 is fixedly provided with a moving plate 407. One side of the moving plate 407 is fixedly provided with a wedge block 408.

[0023] Specifically, the receiving groove 202 communicates with the dust inlet hole 201.

[0024] In this embodiment, by providing the dust inlet hole 201 and the receiving groove 202, the paper scraps generated during the cutting process will be sucked into the receiving groove 202 through the dust inlet hole 201 under the negative pressure suction of the negative pressure fan 205 together with the air, so as to facilitate further treatment of the air containing paper scraps.

[0025] Specifically, a dust collection groove 307 is movably provided on the side of the partition plate 301 away from the negative pressure fan 205.

[0026] In this embodiment, by providing the dust collection groove 307, the paper scraps filtered out by the filter screen 302 will fall into the dust collection groove 307, and the dust collection groove 307 will collect them.

[0027] Specifically, through grooves 409 adapted to the wedge-shaped blocks 408 are formed on both sides of the inner wall of the mounting block 403.

[0028] In this embodiment, by providing the wedge-shaped blocks 408 and the through grooves 409, the wedge-shaped blocks 408 move in the through grooves 409, thereby realizing the disassembly and installation of the cutting knife 404.

[0029] Specifically, a support block 410 is fixedly provided on the other side of the top of the base 1, and an electric push rod 411 is fixedly provided on the top of the support block 410.

[0030] In this embodiment, by providing the support block 410 and the electric push rod 411, the support block 410 provides stable support for the electric push rod 411, improving the accuracy and reliability of the operation of the electric push rod 411.

[0031] Specifically, a push plate 412 is fixedly provided at the telescopic end of the electric push rod 411.

[0032] In this embodiment, by providing the push plate 412, the push plate 412 moves as the telescopic end of the electric push rod 411 extends and retracts, thereby pushing the paper.

[0033] During use, insert the cutting knife 404 into the groove. The wedge block 408 abuts against the mounting block 403 and slides upward. The moving plate 407 moves accordingly and squeezes the second return spring 406. When the wedge block 408 aligns with the through groove 409, under the elastic force of the second return spring 406, the moving plate 407 drives the wedge block 408 into the through groove 409, achieving the purpose of fixing the cutting knife 404. Place the paper on the base 1, adjust the sorting plate to position the paper, and then start the electric push rod 411. The telescopic end of the electric push rod 411 drives the push plate 412 to move, thereby pushing the paper until it is pushed below the cutting knife 404. Start the hydraulic cylinder 402. The mounting block 403 moves downward as the telescopic end of the hydraulic cylinder 402 extends. Thus, the cutting knife 404 cuts the paper. When it is necessary to clean or replace the cutting knife 404, tighten the bolt 405 so that one end of the bolt 405 abuts against the wedge block 408. The wedge block 408 and the moving plate 407 move with the movement of the bolt 405, and the second return spring 406 is squeezed. When the wedge block 408 completely leaves the through groove 409, the staff can remove the cutting knife 404 to facilitate cleaning or replacement, ensuring that the cutting knife 404 always maintains good working performance and is beneficial to enhancing the beauty of the matte paper.

[0034] During the cutting process, start the negative pressure fan 205. The negative pressure suction of the negative pressure fan 205 sucks the paper scraps and air into the receiving groove 202 through the dust inlet hole 201, and then enters the filter box 204 through the air inlet pipe 203. The filter screen 302 filters the gas, and the gas removing the paper scraps is discharged from the air outlet pipe 206. Most of the paper scraps are left on one side of the filter screen 302 and then fall into the dust collecting groove 307. A small part of the paper scraps will adhere to the mesh holes of the filter screen 302. Start the vibration motor 306. After the vibration motor 306 transmits the vibration to the transmission block 305, the transmission block 305 knocks on the filter screen 302, causing the movable block 303 to move towards the side close to the dust collecting groove 307, and the first return spring 304 is stretched. Under the elastic force of the first return spring 304, the movable block 303 drives the filter screen 302 to move left and right, thereby shaking the paper scraps adhering to the mesh holes of the filter screen 302 into the dust collecting groove 307, achieving the purpose of cleaning the filter screen 302. When the dust collecting groove 307 is full, the staff can pull out the dust collecting groove 307 to process the paper scraps in the dust collecting groove 307, providing convenience for the staff.

[0035] In summary, for this matte paper cutting device, by providing a dust inlet hole 201, a receiving groove 202, an air inlet pipe 203, a filter box 204, a negative pressure fan 205, an air outlet pipe 206, and a filter screen 302, the negative pressure suction of the negative pressure fan 205 can suck the paper scraps and air generated during the cutting process through the dust inlet hole 201 into the receiving groove 202, and then enter the filter box 204 through the air inlet pipe 203. The filter screen 302 will filter the gas, and the gas removing the paper scraps will be discharged from the air outlet pipe 206, thereby keeping the working area clean, reducing the risk that the cutting knife 404 is blocked or deviates from the predetermined trajectory due to the accumulation of paper scraps on the cutting path, effectively improving the cutting accuracy and efficiency. At the same time, it also improves the air quality, enhances the comfort of the staff, safeguards the health of the staff. By providing a partition plate 301, a movable block 303, a first return spring 304, a transmission block 305, a vibration motor 306, and a dust collection groove 307, when the vibration motor 306 is started, the vibration motor 306 transmits the vibration to the transmission block 305, so that the transmission block 305 knocks on the filter screen 302. Under the elastic force of the first return spring 304, the movable block 303 will drive the filter screen 302 to move left and right, and then shake off the paper scraps attached to the filter screen 302 into the dust collection groove 307, realizing the automatic cleaning of the filter screen 302, avoiding the blockage of the mesh holes of the filter screen 302 by paper scraps, and improving the filtering efficiency and effect of the filter screen 302. By providing a bolt 405, a second return spring 406, a moving plate 407, a wedge block 408, and a through groove 409, when installing, align the cutting knife 404 with the groove of the mounting block 403. While the cutting knife 404 moves upward, the wedge block 408 abuts against the mounting block 403 and slides upward, and the moving plate 407 moves accordingly. The second return spring 406 is compressed. When the wedge block 408 aligns with the through groove 409, due to the elastic force of the second return spring 406, the moving plate 407 drives the wedge block 408 into the through groove 409, and then installs the cutting knife 404. When disassembling, tighten the bolt 405, and one end of the bolt 405 moves towards the direction of the through groove 409. When one end of the bolt 405 abuts against the wedge block 408, the wedge block 408 and the moving plate 407 move along with the movement of the bolt 405, and compress the second return spring 406 until the wedge block 408 completely leaves the through groove 409. At this time, the cutting knife 404 can be taken out, achieving the purpose of quickly disassembling and installing the cutting knife 404, facilitating its cleaning and replacement, thereby improving the cutting efficiency and effect of the cutting knife 404, and being beneficial to enhancing the aesthetics and quality of the matte paper.
