[0002] PVC film, a thin film material made primarily from polyvinyl chloride, is widely used in industries such as building materials, packaging, and pharmaceuticals. PVC film can be categorized as soft PVC and hard PVC, depending on its composition and production process. Soft PVC contains softeners and is commonly used in applications such as flooring, ceilings, and leather surfaces. Hard PVC, on the other hand, does not contain softeners and offers superior flexibility and formability, resists brittleness, is non-toxic and pollution-free, and has a long shelf life, making it more valuable for development and application.
[0003] A large amount of foreign particles will adhere to the PVC film during the calendering process. In order to reduce these impurities, a cleaning device will be used to clean the surface of the PVC film after the calendering is completed. Two cleaning rollers are mainly used to contact the PVC film to remove the foreign particles on its surface, thereby achieving a cleaning effect. However, due to the light weight and small volume of the dust, some dust is likely to remain, thereby reducing the cleaning effect of the device. Utility Model Content
