[0002] Paper boxes are often used for outer packaging of products in people's daily lives. In actual use, due to the characteristics of the product or design requirements, holes are punched on the side of the paper box through a punching machine.

[0003] In the Chinese utility model patent with the authorization announcement number CN213703672U, a four-side punching machine for a paper box is disclosed, which includes a workbench and a pneumatic system. Four cylinders are evenly distributed circumferentially on the workbench, and the piston rods of the cylinders are all arranged inwardly. A punching mold is provided on the piston rod of the cylinder. A fixed block is provided at the center of the four cylinders on the workbench. The pneumatic system is connected to the four cylinders, and a pressure relief valve and a reversing valve are provided on the pneumatic system. It uses four cylinders to punch holes in the paper box at the same time, which solves the technical problem that a paper box needs to be punched multiple times by a punching machine, and produces a situation where all holes on a paper box can be processed by punching once. At the same time, because the number of punching times is reduced, the danger during operation is reduced.
