When different models of packaging bags need to be made, only screw A11 and screw B13 need to be loosened, and the position of screw A11 in the long strip hole A10 and the position of screw B13 in the long strip hole B12 are readjusted, so as to adjust the distance between the two side plates 3 of the bag making machine, thus achieving the purpose of the packaging machine for packaging different sizes of packaging bags.

[0040] Working principle:

[0041] The packaging film to be formed into a package is tightly installed. The process of tightening the packaging film belongs to the prior art and will not be elaborated and shown here. One end of the packaging film is attached to the outside of the film supporting plate 5, that is, one end of the packaging film is attached to the outside of the vertical plate 6. The end of the packaging film is vertically attached to the outside of the vertical plate 6 and bends horizontally into the space between the two side plates 3 of the bag making machine, and then continues to extend. At the place where the two cover plates 8 are in a V shape, it bends upward, so that the two end parts of the packaging film gradually fold up. As the end of the packaging film continues to extend, the two film combining plates 9 clamp and fix the rectangular end of the packaging film. The width dimension of the pillow-shaped packaging bag is achieved by adjusting the distance between the two film supporting plates 5 and the distance between the two adjusting plates. Subsequently, the seam of the packaging film folded and formed by the two film combining plates 9 is heat-sealed, thus forming a pillow-shaped packaging bag, which belongs to the prior art and will not be elaborated here.
