A clamping area is formed between the material clamp 022 and the first plate 021, and the material clamp 022 is driven by the clamping driving member 023, so that the switching of the clamping area can be realized.

As shown in fig. 1, the first plate 021 is provided with a first notch 211, and the first notch 211 is disposed opposite to the pressing piece 003. When the material stacking rack 002 moves to the position above the base 001, the packaging bag 005 can be folded under the combined action of the material stacking rack 002 and the base 001. The pressing member 003 can pass through the first notch 211 and press and fix the packaging bag 005 on the base 001, and then the stacking drive device 004 drives the stacking frame 002 to translate to leave the upper part of the base 001.
