There are gaps between the plastic film push plate and the second connecting plate and the front side plate, and there are also gaps between the plastic film push plate and the second connecting plate and the rear side plate. The positioning frame is used to position the right ends of the first connecting plate and the second connecting plate on the positioning frame.

2. The device for side tucking and opening of double layer plastic film according to claim 1, characterized in that: The front and rear side panels are symmetrical, and the front and rear side panels are parallel to the first connecting plate. The left and right sides of the front and rear side panels are both vertical edges, and the top left side of the front and rear side panels is higher than the top right side. The top edge of the front and rear side panels is an arc edge.

3. The device for side tucking and opening of double plastic film according to claim 2, characterized in that: The plastic film pusher is parallel to the front and rear side panels respectively, and the second connecting plate is parallel to the front and rear side panels respectively. The left and right width of the plastic film pusher is smaller than the left and right width of the front or rear side panel. The left and right sides of the plastic film pusher are both vertical edges, and the top left side of the plastic film pusher is lower than the top right side. The top edge of the plastic film pusher is an arc edge.

4. The device for side tucking and opening of double layer plastic film according to claim 2, characterized in that: The plastic film pusher plate includes a pusher plate body and a front cover plate. The lower end of the pusher plate body is welded to the upper left end of the second connecting plate. A notch is provided on the lower front side of the pusher plate body, and a cutting tool positioning groove is provided inside the notch. The right end of the cutting tool is installed inside the cutting tool positioning groove, and the front cover plate covers the front side of the notch.

5. The device for side tucking and opening of double plastic film according to claim 4, characterized in that: The push plate body is provided with screw holes, the cutting blade and the front cover plate are provided with connecting holes corresponding to the screw holes, and the inward folding and opening mechanism is provided with connecting screws. After the connecting screws pass through the connecting holes of the cutting blade and the front cover plate, they are screwed into the screw holes, so that the push plate body, the cutting blade and the front cover plate are detachably locked together.

6. The apparatus for folding and opening the sides of a double-layer plastic film inward according to claim 5, characterized in that: The cutting blade is set at an angle, with the height of the right end of the cutting blade being the same as the height of the left end, and the cutting edge of the cutting blade facing upwards.

7. The device for side hem turning and opening of double layer plastic film according to claim 1, characterized in that: The first connecting plate has multiple first waist-shaped mounting holes from left to right, and the second connecting plate has multiple second waist-shaped mounting holes from left to right.
