[0030] Work process:

[0031] Guided by the first guide roller 4, the film passes between the two sponge sleeves 5-4. The sponge sleeves 5-4 absorb moisture from the film surface upon contact, thus performing a preliminary water absorption and dehumidification operation. The squeezing plate 5-12 squeezes the sponge sleeves 5-4, causing the absorbed water to be squeezed out and collected in the water collection tank 5-9. The water is then discharged through the drain hose installed on the water collection tank 5-9, which greatly improves the water absorption efficiency of the sponge sleeves 5-4. At the same time, high-pressure gas can be introduced from the pneumatic rotary joint 5-5 into the first rotating shaft tube 5-3 and the second rotating shaft tube 5-6. The high-pressure gas dries the sponge sleeves 5-4 from the inside out, thus avoiding frequent replacement of the water absorption roller composed of the rotating shaft tube and the sponge sleeves 5-4 and extending the water absorption cycle.

[0032] Under the guidance of the first guide roller 4 and the second guide roller 9, the film after passing through the water absorption assembly 5 passes from the air outlet of the first air outlet 7 and the second air outlet 8, air enters the first air outlet 7 and the second air outlet 8, and the filter in the first air outlet 7 and the second air outlet 8 filters the moisture and dust impurities in the air to avoid the moisture and dust impurities in the air reducing the quality of the film. Subsequently, the filtered air contacts the film, and at the same time, the flowing air is discharged from the air outlet of the protective cover 10, and the film is dried again by the rapid flow of air, and at the same time, the molecular force between the cooled film increases, reducing the force of pulling the film during winding, and improving the surface quality of the film.
