The anti-suction scraping gun adopts a new compact design and can be installed anywhere on the production line. Simple design, convenient for installation and maintenance. Equipped with a patch type solenoid valve can better increase the response speed of the scraping gun, and the number of interruptions can reach 10,000 times/min, maximizing production efficiency. The high-speed reverse pumping mode ensures intermittent and non-smearing so that it has excellent results in applications such as labels and sanitary napkin adhesives.
