Description

Technical Field

[0002] Silicone protective film is a commonly used protective material, which is widely used in the fields of electronic products, glass products, ceramic products, etc. In the production process of silicone protective film, a coater is needed for coating processing.

[0003] Chinese patent with publication number CN213349522U discloses a coater for producing silicone protective film, which includes an iron base plate. Support leg mechanisms are fixedly welded to the four peripheral positions at the bottom of the iron base plate. Coating conduction mechanisms are fixedly welded to the left and right sides at the top of the iron base plate. Sliding mechanisms are symmetrically arranged on the left and right sides at the top of the iron base plate between the two groups of coating conduction mechanisms. Recycling boxes are fixedly installed on the front and rear sides at the top of the two groups of sliding mechanisms. Telescopic mechanisms are fixedly installed at the middle positions of the top ends of the left and right side walls of the two groups of recycling boxes. Magnets cooperating with the iron base plate are fixedly installed at the bottoms of the four groups of telescopic mechanisms. An installation frame is fixedly welded at the middle position at the top of the iron base plate behind the two groups of sliding mechanisms.

[0004] Although the above coater drives the support square frame to move up and down through the telescopic movement of four cylinders, thereby driving the iron base plate and the installation frame to move synchronously, and then adjusting the height of the coater, so as to adjust the tension of the silicone protective film. However, when coating the silicone protective film, it can only coat the surface and cannot coat the bottom surface. Moreover, it is inconvenient to dry after coating, the drying speed is slow and the time consumption is long, which affects the processing efficiency. Therefore, it is urgently needed to be improved.
