The second die-cutting roller 44 is also rotatably connected to the machine body 1, which can also assist in conveying the cardboard.

[0025] Below the front slotting section 3 and the rear slotting section 4, there is also a waste discharge conveyor belt 5. By providing the waste discharge conveyor belt 5, the waste paper scraps that have been slotted can be collected and transported.

[0026] The working principle of this utility model is as follows: A front grooving section 3 and a rear grooving section 4 are sequentially arranged in the machine body 1. The front grooving section 3 is equipped with a first grooving knife 30 for grooving the cardboard, and the rear grooving section 4 is equipped with a second grooving knife 40 for grooving the cardboard again. When the cardboard needs to be grooved, the first grooving knife 30 first grooves one side of the cardboard. When the cardboard is conveyed backward, the second grooving knife 40 of the rear grooving section 4 then grooves the other side of the cardboard again. This can greatly speed up the cardboard grooving efficiency. When dealing with cardboard of smaller size that needs to be grooved, there is no need to worry that the limited distance between the first grooving knife 30 and the second grooving knife 40 will prevent it from being used for grooving smaller cardboard, thereby increasing the versatility of the overall equipment.
