Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective film processing, in particular to a protective film gluing device. Background Art
[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservation protective films, etc. according to their uses. 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 their functions in the field of screen protective films are also varied. In the production and processing of many protective films, a coating machine is required to coat and glue the surface in order to achieve compounding with release film or other films.
[0003] The existing protective film coating and gluing process has the following disadvantages: the existing film gluing is generally applied by roller coating, with half of the coating roller immersed in the glue box and the film surface is coated with glue during the rotation. In actual use, due to the influence of the characteristics of the colloid material, it is easy to condense and agglomerate inside the glue box. If it is not cleaned in time, the glue blocks will adhere to the surface of the coating roller, affecting the uniformity of the gluing during coating and easily causing wear of the film. For this reason, we propose a protective film gluing device. Utility Model Content
