Common micro gravure precision coating method --

Micro gravure coating:
     The coating roller is an anilox roller, and the diameter is generally between Φ20mm-Φ50mm, so it is called micro gravure coating, which is a direction, contact coating method, that is, the rotation direction of the micro coating roller and the film film. The feed direction is reversed and the film is not pressed onto the coating roll by the press rolls. Conventional gravure coating methods, whether direct coating or reverse coating, generally have a back pressure rubber roller and an anilox roller having substantially the same diameter as the rubber. Since the film is pressed between the rubber roller and the anilox roller, there is a possibility that defects such as wrinkles and cracks appear on the coated surface, and the pressure contact points of the two rolls affect the coating quality due to factors such as mechanical and pneumatic pressure.
     While micro gravure coating is a contact coating, contact coating means that there is no back pressure rubber roller, and therefore some potential disadvantages due to back pressure roller pressurization are eliminated.

Micro gravure coating application case:
- 1 - 
Light-shielding film, various optical films, materials for lithium batteries, various composite tapes, film films, and protective films. Comma roll coating:
     The comma roll coating is characterized by a combination of a blade scraper and a roller scraper. The effect of the thickness of the glue is smaller than that of the blade, the thickness of the coating is easily adjusted, and the high viscosity glue can be applied. When the width is large, it can be adjusted horizontally.
advantage:
1. The strength and hardness of the comma scraper are high, and the straightness error of the cutting edge is small. The pneumatic fine adjustment mechanism can be used to adjust and control the position of the scraper, and the coating amount control and scraping precision are high.
2. It can coat thicker coating. When coating, the glue flows from top to bottom between the blade mouth and the film. Therefore, the glue can be fully used, and there is basically no waste of glue.
Disadvantages:
1. The coating quality of the comma roller coating has a great relationship with the operation of each component unit, especially the transmission ratio between the driving motor and the rotating pressing roller is difficult to adjust, which often causes uneven coating and is prone to lateral or Longitudinal irregular stripes. When coating, the glue easily flows out in the gap between the baffle and the drive press roller, and the sealing property is not complete. When coating, it is necessary to manually stir the glue of the glue storage tank. To guarantee
Even distribution of the glue.
