[0003] During the production process of packaging boxes, product appearance, product name, merchant brand name, etc. are printed on the surface of the packaging boxes to meet customer needs. The packaging boxes are usually cut when they are printed. After cutting, some scraps will be attached to the outer surface of the packaging box, or some scraps will not fall off completely at the cutting edge. At this time, it is usually necessary to manually remove the scraps on each packaging box.

[0004] The traditional method of removing scraps from the surface of packaging boxes is mainly done manually. When the scraps of packaging boxes need to be removed in batches, the manual workload cannot be reduced. Manual removal often results in omissions, which is not conducive to the stacking, packaging or further processing of the packaging boxes. Utility Model Content
