The fifth air cylinder 264 can drive the bag opening suction cup brackets 265 and 266 to synchronously move back and forth, wherein the synchronous back and forth movement refers to that when the bag opening suction cup bracket 265 moves forward, the bag opening suction cup bracket 266 simultaneously moves backward; when the bag opening suction cup holder 265 moves backward, the bag opening suction cup holder 266 moves forward at the same time, that is, the bag opening suction cup holder 265 and the bag opening suction cup holder 266 move in the opposite direction or in the opposite direction in synchronization. Thus, 4 vacuum chucks move synchronously to suck and open the packaging bag. It should be noted that the heights of the 4 vacuum suction cups of the bag opening portion may be the same as the heights of the 4 chucks of the first clamping portion.

When the first bag opening assembly 20 performs the bag opening action, the clamping heads 216 and 218 move towards the clamping heads 215 and 217 synchronously, the clamping heads clamp the packaging bags after approaching contact, and the clamping positions can be positioned at the left side and the right side of the bag opening. And then, the vacuum suction cups are close to and contact with the packaging bags, the vacuum suction cups suck the bags from two sides respectively, and the positions where the vacuum suction cups suck the bags can be the middle positions of the bag openings.
