[0033] It should be noted that in the process of processing the aluminum plastic film, the aluminum plastic film belt will first pass through the deep drawing device to perform punch drawing on the aluminum plastic film belt by the deep drawing device to form a plurality of deep drawing holes on the aluminum plastic film belt. Then, the aluminum plastic film belt needs to be moved to the cutting device to perform fixed-length cutting on the aluminum plastic film belt by the cutting device to form a plurality of aluminum plastic film pieces, and then the aluminum plastic film pieces are stacked to facilitate subsequent storage and transportation of the aluminum plastic film pieces.

[0034] However, after the deep drawing device punches and draws on the aluminum plastic film belt, the stress of the aluminum plastic film belt at the deep drawing hole is large, so that the area around the deep drawing hole on the subsequent aluminum plastic film piece will be raised due to uneven stress, thereby affecting the stacking of the subsequent aluminum plastic film piece.
