The role of the scraper of the Hot melt adhesive coating machine (2).

The scraper function of the Hot melt adhesive coating machine:

(1) Scraper pressure At present, the scraper used for scraping glue on anilox rollers basically uses stainless steel blades. When the hot melt adhesive coating machine is coated, the pressure of the scraper acting on the anilox roller is  too small, and when there are impurities, the scraper will be jacked up to cause a gap, so that the Hot melt adhesive coating machine is uneven and the amount of coating increases. The factors affecting the pressure of the scraper are: the softness of the blade and the angle between the scraper and the anilox roller. In the actual CAO operation, it is appropriate to adjust the scraper with a pressure hammer, and the scraper pressure is generally about 200~400kPa.
