1. It is provided with anilox roller plus blade for coating mode, and also provided with many selection opportunities of anilox roller with various coating amount.
2. It is provided with separate five-section type constant temperature drying system using infrared stainless steel heating tube plus beating wind, as wellas adjustable interior circulation air draining and suction devices. It is advantageous in strong wind-exit and wind entrance, helping drying thoroughly.
Characteristics of several coating methods -
These scrapers are made of high-precision cold-drawn round steel wrapped around stainless steel wire. If the wire scraper is rotated by the micro DC motor during the scraping, the effect is better. The wire scraper usually acts directly on the substrate when the glue is applied. However, it is generally only used for the pre-squeegee coating of the smooth roll. A precise squeegee of a comma blade is usually required later.
The air squeegee mechanism acts on the sizing roller by a uniformly sprayed gas (pressure) flow, which serves the purpose of squeegeeing. The gas (pressure) flow is required to be evenly distributed over the entire width of the optical roll, and this type of scraper is often used for scraping a good fluidity. The scraper has a high precision of scraping, and is currently widely used for coating scraping of whiteboard paper.
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.
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.
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.
