Masking Paper Coating Machine

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.

Characteristics of several coating methods -

Wire scraper
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.

Air squeegee
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.
