Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a device for pasting protective films. Background Art

[0002] According to the purpose, protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and protective film pasting devices are required when using protective films.

[0003] After searching, the announcement number CN217196940U is a device for pasting protective film, including a device body, an oil storage tank is fixedly connected inside the device body, an oil filling port is opened on the top of the device body, a lifting frame is arranged inside the device body, a first connecting pipe is fixedly connected inside the lifting frame, a pressurizer is fixedly connected inside the lifting frame, a second connecting pipe is arranged inside the lifting frame, a connecting plate is fixedly connected to the bottom of the lifting frame, a driving roller is rotatably connected to the bottom of the connecting plate, and a rotating roller is fixedly connected to the outside of the driving roller. The device for pasting protective film injects heat transfer oil into the oil storage tank through the oil filling port, and then the heat transfer oil flows from the first connecting pipe to the second connecting pipe through the pressurizer, and then flows to the rotating roller. At this time, the heat transfer oil inside the rotating roller flows to the heat transfer oil roller through the injection pipe. Under the action of the heat transfer oil, the film can be heated to remove bubbles when pasting, thus avoiding the defect of flattening wrinkles in the film.

[0004] Based on the above patent, the heat transfer oil is injected into the oil storage tank through the oil filling port, and then the heat transfer oil is made to flow from the first connecting pipe to the second connecting pipe through the pressure booster, and then flows to the rotating roller. At this time, the heat transfer oil inside the rotating roller flows to the heat transfer oil roller through the injection pipe. Under the action of the heat transfer oil, the bubbles can be heated and discharged when the film is pasted, thus avoiding the defect of flattening wrinkles in the film. However, due to the dust particles on the film-pasted product, bubbles will be generated when the film is pasted, affecting the quality of the film. Utility Model Content
