The symmetrically distributed first telescopic cylinders 7 can push the limiting plate 11 to move smoothly to limit the wound plastic bag.

[0024] Specifically, Figure 1 and Figure 3As shown, the first telescopic cylinder 7 is started to push the limiting plate 11 to move to a suitable position on one side of the storage roller 16, thereby limiting the two sides of the plastic bags wrapped around the outer wall of the storage roller 16, so that the plastic bags are evenly overlapped and wrapped together.

[0025] A connecting seat 14 is fixed to both ends of one side of the mounting frame 1, and a cooling fan 13 is installed at one end of the connecting seat 14;

The heating roller 3 is turned on by the temperature controller 9 to iron and squeeze the plastic bag passing through the heating roller 3 so that the plastic bag becomes flat. Then, the plastic bag passes through the cooling fan 13. The cooling fan 13 is started to cool down the hot plastic bag after ironing and flattening. Then the servo motor 4 is started to drive the storage roller 16 to wind and store the flattened plastic bag.
