Description

Technical Field

[0001] This utility model belongs to the technical field of coating devices, and specifically relates to a coating device. Background Technology

[0002] Coating refers to the method of applying a paste polymer, molten polymer, or polymer solution onto paper, cloth, or plastic film to obtain a composite material (film). Coating requires the use of a coating device.

[0003] Chinese utility model CN222152615U discloses a film coating apparatus, including a laminating machine wall panel, on which are mounted a coating steel roller, a metering roller, an eccentric roller, a coating transfer roller, an unwinding guide roller, and a drive device. The laminating machine wall panel also has a rotating steel roller mounting and disassembly structure. The metering roller is located on one side of the coating steel roller and can move horizontally relative to the coating steel roller, forming a coating gap between the coating steel roller and the metering roller. The coating transfer roller is located below the coating steel roller and can move vertically relative to the coating steel roller, forming a coating gap between the coating steel roller and the coating transfer roller. In the coating gap, the adhesive transfer roller and metering roller are rotatably connected to the laminator wall panel via a rotating steel roller assembly / disassembly structure. The unwinding guide roller is rotatably connected to the upper side of the laminator wall panel. The drive unit is connected to both the metering roller and the adhesive transfer roller, and rotatably connected to the eccentric roller on the laminator wall panel. During the coating process, the material is first introduced by the unwinding guide roller, closely adhering to the adhesive steel roller as it enters the coating gap. Then, it passes through the coating gap along the adhesive transfer roller for secondary coating. Finally, the material bypasses the outer side of the adhesive transfer roller and is discharged after adjustment by the eccentric roller. Traditional coating devices use rollers to coat the material. For thin film materials, the pressure from the rollers easily causes wrinkling, leading to a decrease in product quality.

[0004] Therefore, there is an urgent need to propose a new technical solution to address the above problems. Utility Model Content
