10. Use method of a plastic bag manufacturing apparatus with a flattening function according to any one of claims 1 to 9, characterized in that: the method comprises the following steps:
the method comprises the following steps: feeding:
firstly, placing a produced plastic bag on the top of a conveyor belt (2), and then conveying the plastic bag to the inside of a case (1) for leveling operation by starting the conveyor belt (2);
step two: adjusting:
then the leveling roller (12) is arranged between the movable mounting plates (11), the hand wheel disc (28) is screwed, the hand wheel disc (28) drives the rotating shaft (13) to rotate, the rotating shaft (13) rotates through the meshing of the transverse bevel gear (14) and the two vertical bevel gears (16), so that the two second screw rods (15) rotate through the rotation of the two vertical bevel gears (16) respectively, and the two movable mounting plates (11) move oppositely and oppositely, and the leveling roller (12) is fixed and replaced;
