At the same time, the spacing adjustment mechanism 4 can be adjusted according to the pressure rollers 7 of different lengths, so that the pressure of the pressure rollers 7 is balanced, thereby increasing the practicality of the balance adjustment mechanism. At the same time, when the plastic bag passes through the wrinkle removal roller 1202, due to the different heights between the wrinkle removal roller 1202 and the pressure roller 7, the wrinkle removal roller 1202 will exert a force on the plastic bag, thereby reducing the probability of wrinkles in the plastic bag during processing.
