The waste recycling system for the production of foldable waste liquid collection PE film as described in claim 7, characterized in that, The discharge chute includes an inclined chute, two elastic rods, and a vibration motor; The inclined slide is rotatably mounted on one side of the cleaning tank; the two elastic rods are rotatably connected to the inclined slide and to the cleaning tank respectively, and are located at the bottom of the inclined slide respectively; the vibration motor is fixedly mounted at the bottom of the inclined slide.

9. A waste recycling system for the production of foldable waste liquid collection PE film as described in claim 8, characterized in that, The elastic rod includes a sleeve, a slide bar, a stop block, and a spring; The sleeve is rotatably connected to the cleaning tank and located on one side of the cleaning tank; the slide rod is slidably connected to the sleeve and located inside the sleeve; the stop block is fixedly disposed on one side of the slide rod and rotatably connected to the inclined slide rail; the spring is sleeved on the slide rod and located between the sleeve and the stop block.

10. A method for recycling production waste from a foldable waste liquid collection PE membrane, comprising a production waste recycling system for a foldable waste liquid collection PE membrane as described in any one of claims 2-9; characterized in that, include: The production waste of PE film is crushed into small pieces using a crusher. Water and cleaning agent are added to the washing tank, and the production waste is poured into the U-shaped frame and soaked for a period of time. The reciprocating drive mechanism drives the U-shaped frame to slide up and down repeatedly, cleaning the production waste for a period of time. After the wastewater in the cleaning tank is drained, clean water is refilled, and the reciprocating drive mechanism drives the U-shaped frame to slide up and down repeatedly to continue cleaning the production waste for a period of time. The lifting mechanism raises the U-shaped frame, so that the perforated plate is a certain distance away from the liquid surface. Then, the reciprocating drive mechanism drives the U-shaped frame to slide up and down repeatedly, shaking off the water on the production waste and performing preliminary dehydration. The lifting mechanism raises the U-shaped frame so that the top surface of the perforated plate is flush with the top surfaces of both sides of the cleaning pool. The horizontal drive mechanism drives the push plate to push the cleaned production waste on the top of the perforated plate onto the discharge chute, from which it falls.
