The operating platform is provided with a limiting port 13. A rectangular frame 3 is provided in the limiting port 13. The lower part of the rectangular frame 3 extends above the beginning of the conveyor belt 2. A limiting groove 31 is provided on the inner wall of the X direction side of the rectangular frame 3. A detachable scraper 32 is provided in the limiting groove 31. A first opening 33 is provided at the lower part of the limiting groove 31. A fixed seat 4 that can move along the X direction or in the opposite direction of the X direction is provided at the first opening 33. The upper part of the fixed seat 4 abuts against the lower part of the scraper 32. The driving device 5 is used to drive the fixed seat 4 to move.

[0029] In the above embodiments, it should be noted that the cutting and positioning component 12 has the same structure as that in the authorized announcement CN217861557U. First, the cardboard to be cut is placed on the upper part of the fixed base 4, and then the cutting and positioning component 12 is used to cut it. After the cutting is completed, the drive device 5 is turned on, so that the fixed base 4 moves along the X direction. The scraper 32 scrapes off the paper scraps on the fixed base 4. The scraped paper scraps fall onto the conveyor belt 2 below for conveying and collection. Compared with the prior art, it can automatically clean up light or electrostatically adsorbed paper scraps without the need for manual cleaning.

[0030] As an optional implementation, the lower Y-direction or reverse Y-direction inner wall of the rectangular frame 3 is provided with a strip support plate 34.

[0031] In the above embodiments, the stability of the fixing base 4 can be further improved.

[0032] As an optional implementation, the drive device 5 includes a lead screw guide assembly 51, a slider 52, a first bevel gear 53, a second bevel gear 54, a first rotating shaft 55, a second rotating shaft 56, and a drive motor 57. The lead screw guide assembly 51 is connected inside the collection box 1 and is located on the X-direction side of the rectangular frame 3. The axis of the lead screw guide assembly 51 is in the X-direction. The slider 52 is connected to the lead screw guide assembly 51. The fixed seat 4 is connected to the slider 52. The first rotating shaft 55 is driven by the lead screw guide assembly 51. The first bevel gear is coaxially connected to the first rotating shaft 55. The second rotating shaft 56 is connected to the top of the inner wall of the collection box 1. The second bevel gear 54 is coaxially connected to the lower part of the second rotating shaft 56 and meshes with the first bevel gear 53. The drive motor 57 is connected to the top of the outer side of the collection box 1 and is driven by the second rotating shaft 56.

[0033] In the above embodiments, by setting the drive motor 57 on the top of the outside of the collection box 1, it is convenient for the staff to turn on the drive motor 57, thereby causing the fixed seat 4 to move in the opposite direction along the X direction, and then the scraper 32 scrapes the paper scraps on the fixed seat 4 cleanly. At the same time, the lead screw guide rail assembly 51 makes the movement of the fixed seat 4 more stable.

[0034] As an optional implementation, the paper product processing cutting device also includes a mounting block 6, which has a groove 61 that matches the scraper 32. The mounting block 6 fixes the scraper 32 in the groove 61 by bolts 62. The collection box 1 has mounting ports 15 that match the shape of the scraper 32 on both sides in the Y direction or the opposite side of the Y direction. The mounting ports 15 are connected to the limiting groove 31.

[0035] In the above embodiments, by inserting the scraper 32 along the mounting port 15, so that both sides of the scraper 32 are outside the mounting port 15, and then matching the groove 61 of the mounting block 6 with the scraper 32, the scraper 32 is provided with a threaded hole, and the inner wall of the groove 61 is provided with a through hole that matches the threaded hole. By passing the bolt 62 through the through hole and the threaded hole in sequence, the scraper 32 is fixed in the groove 61. Then, the mounting block 6 is fixed to the outer side wall of the collection box 1 in the Y direction and the opposite direction of the Y direction, thereby fixing the scraper 32 in the limiting groove 31. It can be detached and installed, which is convenient for replacing the scraper 32.

[0036] As an optional implementation, the inner walls of the rectangular frame 3 in the Y direction and the opposite direction of the Y direction are provided with a second opening 35. The second opening 35 is located above the support block on the side closer to the X direction. A push block 7 that moves along the Y direction or in the opposite direction of the Y direction is provided at the second opening 35. A cylinder 14 is provided on the outer walls of the collection box 1 in the Y direction and the opposite direction of the Y direction. The piston rod of the cylinder 14 is connected to the push block 7. The cylinder body axis of the cylinder 14 is in the Y direction.

[0037] In the above embodiments, since a support block is provided, when the scraper 32 scrapes away paper scraps, some paper scraps may fall onto the side of the support plate closer to the X direction. Driven by the cylinder 14, the pusher 7 will dislodge the paper scraps located on the side of the support plate closer to the X direction onto the conveyor belt 2, further enhancing the paper scrap cleaning effect.

[0038] Working principle: When the cardboard needs to be cut in half, mark it, then place the cardboard on the upper part of the fixed seat 4, so that the blade of the cutting positioning component 12 is directly above the mark on the cardboard. Then, the cardboard is cut by pressing down with the blade of the cutting positioning component 12. The rectangular frame 3 can concentrate the cut paper scraps on the fixed seat 4 inside the rectangular frame 3. By moving the fixed seat 4, in conjunction with the scraper 32, the paper scraps on the fixed seat 4 are scraped off onto the conveyor belt 2 at the lower part of the rectangular frame 3 for conveying. Since the support plate is located below the fixed seat 4, some of the scraped paper scraps will fall onto the support plate. By using the cylinder 14 to drive the pusher 7 to move, the paper scraps on the support plate are scraped off onto the conveyor belt 2, thereby enhancing the cleaning of paper scraps.
