Characteristics of several coating methods -

Stainless steel scraper
The scraper is sheared by a stainless steel sheet and pressed against the blade holder and applied to the upper (coating) rubber roller. Since the stainless steel sheet is soft, the squeegee is not very uniform, and most of the squeegee used on the anilox roll is also used for pre-scraping of the glazing coating.

Comma scraper
Such scrapers are often made of round steel with good strength and hardness. The blade is fixed and does not rotate when the glue is scraped. The strength of the scraper is high, the hardness of the blade is small, and the pneumatic and fine adjustment mechanism can be used to adjust and control the position of the scraper. The coating amount control and the scraping precision are high, and the use is also extremely convenient. Due to its uniform squeegee, it is suitable for precise squeegee coating on smooth rolls.

Bar scraper
This type of scraper is usually made of round rods with good strength and hardness. The round bar is required to rotate when scraping the glue. Sometimes the bar can also be scraped directly onto the substrate. The full runout error of the scraper bar is very small, and it is mostly used for the pre-squeegee coating of the glue bar coating on the light roller. When the glue is sticky, it can also be directly scraped on the substrate with a scraper as a precise scraping agent for the coating mechanism. It can also be used for coating a thicker disposable squeegee.

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.
