After the connecting shaft 16 moves up and down, it drives the tension roller 17 to move up and down. By adjusting the height change between the tension roller 17 and the stretching and winding roller 5, the tension during the stretching and winding of the plastic packaging film is adjusted to avoid the phenomena of position loosening and breakage during the stretching and winding of the plastic packaging film due to uneven tension. When limiting plastic packaging films of different sizes, the position of the limiting ring 21 on the tension roller 17 can be adjusted according to the size of the plastic packaging film. When adjusting the limiting ring 21, the two second threaded rods 18 can be rotated to drive the two guiding strips 20 to perform relative reciprocating movements. After the two guiding strips 20 perform relative reciprocating movements, they drive the two limiting rings 21 to perform relative reciprocating movements on the tension roller 17, so as to adapt to plastic packaging films of different sizes, guide and limit plastic packaging films of different sizes, and prevent the phenomenon of deviation.
