[0024] Working principle: First, place the packaging bag on the workbench 1, and prevent the position where the packaging bag needs to be folded from being directly above the through slot 8. The telescopic end of the second cylinder 13 drives the fixed seat 10 to move downward. The slide rail 11 and the slide seat 12 can ensure the stability of the fixed seat 10 during movement. The fixed seat 10 drives the bending plate 6 and the insert plate 7 to move downward. The insert plate 7 moves downward until it is inserted into the through slot 8. The folded part of the packaging bag falls under the workbench 1. At this time, the telescopic end of the second cylinder 5 controls the insert plate 7 to move upward until it exceeds the surface of the workbench 1.
