When the second piston slides in the direction away from the inflation flow channel, the air pressure in the inflation flow channel decreases, and the outside air enters the inflation flow channel through the fourth one-way valve, thereby realizing air supply to the inflation flow channel; when the second piston slides in the direction close to the inflation flow channel, the air pressure in the inflation flow channel increases, and the air in the inflation flow channel impacts the back of the packaging paper through the third one-way valve, thereby realizing the cleaning of impurities on the back of the packaging paper, so that the packaging paper can be packaged and stored after printing is completed, thereby improving the printing efficiency of the packaging paper.

In the embodiment, there are two starting parts 214, and the ends of the two starting parts 214 are fixed at intervals on the surface of the support part 212. The elastic part 213 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic part 213 is a compression spring with a certain deformation ability. One end of the elastic part 213 in the elastic direction is connected to the bottom wall of the support cavity 2111, and the other end of the elastic part 213 in the elastic direction is connected to the surface of the support part 212. The elastic part 213 has an elastic force that drives the support part 212 to slide in a direction away from the support cavity 2111, and the end of the support part 212 tends to protrude from the surface of the rotating part 211.
