a plurality of packaging bags are regularly arranged on the conveyor belt 3, and the sealing ends of the packaging bags are arranged on the side far away from the rotating motor 2;

starting the rotating motor 2 to drive the conveyor belt 3 and the rotating disc 4 to rotate at the same speed, referring to fig. 1, arrow marks on a first linkage gear 9 and a second linkage gear 10 in fig. 1 represent the rotating directions of the first linkage gear 9 and the second linkage gear 10, the rotating directions of the conveyor belt 3 and the second linkage gear 10 are consistent, and the rotating directions of the rotating disc 4 and the first linkage gear 9 are consistent;

the conveyor belt 3 drives the packaging bags on the conveyor belt 3 to move forwards, when the packaging bags move to the position right below the rotating disc 4, the rubber layer 26 on the balance weight block 5 at the lowest position in the rotating disc 4 abuts against the upper surface of the packaging bags, the packaging bags are twisted and opened through the difference of the running speeds of the rotating disc 4 and the conveyor belt 3, the openings of the packaging bags are opened by partial gaps, meanwhile, gas is sprayed out of the two fixed blocks 23 at the lowest position, and the gas enters the packaging bags through the partial gaps of the packaging bags, so that the packaging bags are inflated;

as the conveyor belt 3 runs, the inflated package bag is released from contact with the rubber layer 26 and is finally conveyed to a production area where the paper products are packaged, thereby facilitating the packaging work for workers.

It should be noted that the side length of the rubber layer 26 on the counterweight 5 is smaller than the side length of the opening of the packaging bag, so that an open gap is formed when the packaging bag is twisted and opened, and the gas of the fixing block 23 is conveniently sprayed.
