When the bag body needs to be moved, the negative pressure adsorption head 17 on the lower conveying module 13 releases the negative pressure and moves forward, and the negative pressure adsorption head 17 on the lower conveying module 13 is released. When the negative pressure adsorption head 17 on the lower conveying module 13 is relative to the previous negative pressure adsorption head 17 on the upper conveying module 12, the negative pressure adsorption head 17 on the lower conveying module 13 starts to negatively pressure adsorb the bag body, and at the same time, the negative pressure adsorption head 17 on the upper conveying module 12 releases the negative pressure, and at the same time, the lower conveying module 13 moves backward. When the lower conveying module 13 is relative to the negative pressure adsorption head 17 on the upper conveying module 12, the negative pressure adsorption head 17 on the lower conveying module 13 and the upper conveying module 12 are both in a negative pressure state, so that the bag body is transported by the reciprocating movement of the lower conveying module 13; a trigger valve 22 is set on the negative pressure adsorption heads 17 of the upper conveying module 12 and the lower conveying module 13, and the negative pressure adsorption heads 17 on the upper conveying module 12 and the lower conveying module 13 are controlled by the trigger valve 22.
