[0035] A cleaning part 4 is arranged between the bottomless slitting box 2 and the slitting table 1, and is used to clean the paper scraps generated during the slitting of the paperboard.

[0036] A paper scrap intercepting part 5 is arranged to prevent the paper scraps from leaking out of the feeding groove 8 and the discharging groove 9.

[0037] A driving part 7 is arranged to drive the conveying part 6 and the cleaning part 4 to operate and drive the slitting knife roller 3 to rotate.

[0038] The feeding groove 8 and the discharging groove 9 are actively blocked by the paper scrap intercepting part 5, so that the bottomless slitting box 2 can form a semi-closed state during the slitting of the paperboard, and the air in the bottomless slitting box 2 and the paper scraps generated during the slitting can be extracted by the cleaning part 4, thereby further improving the semi-closed effect of the bottomless slitting box 2, avoiding the paper scraps generated during the slitting from overflowing into the working environment and affecting the health of the workers, improving the paper scrap recycling effect, facilitating the reuse, reducing the material waste consumption in the production process, and saving the production cost.

[0039] As shown in Figure 4 and Figure 5 , the cleaning part 4 comprises:
