Several Scrapers Needed In The Process Of Textile Printing And Coating

Stainless steel sheet scraper

The scraper is sheared by stainless steel sheet, pressed on the scraper base and acted on the upper (coating) rubber roller. Because the stainless steel sheet is soft, the glue scraping is not very uniform. Most of them are used for the glue scraping on the anilox roll, and also for the pre scraping of glue coating on the smooth roll.

Comma scraper

This kind of scraper is usually made of round steel with good strength and hardness. The scraper is fixed and does not rotate during rubber scraping. This kind of scraper has high strength, high hardness, and small straightness error of the edge. Pneumatic and fine adjustment mechanisms can be used to adjust and control the position of the scraper. The coating amount control and scraping precision are high, and it is also very convenient to use. Due to its uniform glue scraping, it is suitable for precise glue scraping of glue coating on smooth roll.

Scraper rod

This kind of scraper is usually finished with a round bar with good strength and hardness. The round bar shall rotate when scraping. Sometimes the scraping rod can also be directly scraped on the substrate. The total run out error of the squeegee is very small, and it is mostly used for pre scraping of glue coating of the squeegee type squeegee device on the smooth roll. When the glue is sticky, it can also be directly scraped on the substrate with a scraper as the precise scraping of the coating mechanism. Can also be used for coating Thicker one-time glue scraping.

Steel wire scraper

This kind of scraper is made of high-precision cold drawn round steel with stainless steel wire wrapped tightly. The effect is better if the steel wire scraper is driven by a micro DC motor when scraping rubber. When scraping glue, the steel wire scraper usually acts directly on the base material. But generally speaking, it is only used for pre scraping glue of glue coating on smooth roll. The exact glue scraping of the comma scraper is usually required later.

Air flow scraper

The air flow scraper mechanism acts on the gluing polishing roller through the evenly ejected air (pressure) flow, so as to scrape the glue. The air (pressure) flow is required to be evenly distributed over the entire width of the polishing roll. This scraper is mostly used to scrape the glue with good fluidity. The scraping precision of this scraper is also high, and it is widely used in the coating of white board at present Squeegee 。
