Description

Technical Field

[0001] The utility model relates to the technical field of protective film coating, in particular to a protective film coating pretreatment device. Background Art

[0002] Coating machines are mainly used for surface coating production of films, papers, etc. This machine coats the rolled substrate with a layer of glue, coating or ink with specific functions, and cuts it into sheets or rolls it up after drying. It uses a special multi-functional coating head to achieve various forms of surface coating. The reel and unreel of the coating machine are equipped with full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control.

[0003] During the protective film coating process, if there is dust on the surface of the film, paper, etc. to be coated with the protective film, if it is not removed in advance, it will affect the subsequent coating effect of the protective film, making the coating effect poor. Currently, most people use sticky paper rolls to remove dust from the protective film, but once the sticky paper roll is adsorbed to a certain amount, it is necessary to stop the machine and tear off the outer adhesive layer before continuing to use it, but this will lead to a decrease in the winding efficiency. Therefore, we propose a protective film coating pretreatment device to solve this problem. Utility Model Content
