PVA water-soluble film steel strip machine

The PVA water-soluble film steel strip machine first produces a water-soluble adhesive solution from the raw materials under certain conditions, and then flows the adhesive solution onto a mirror stainless steel strip (hereinafter referred to as the steel strip). The adhesive solution is evenly scraped off with a scraper, and the scraper layer of the adhesive solution is dried in the drying oven with the rotation of the steel strip, and peeled off into a finished film. The heat source of the drying oven comes from the heat supply box arranged in the system section and the infrared electric heating tube built into the drying oven, and the temperature inside is controllable. The scraper is fixed on the upper part of the steel strip and can be adjusted up and down within a certain range. By controlling the gap between it and the steel strip, the thickness of the water-soluble film can be controlled. The steel strip is welded into a ring shape and installed on a pair of large rollers. The active roller is located at the rear of the production line, while the front roller mainly plays a role in changing direction, called the changing direction roller. The rigid belt transmission is very similar to the flat belt transmission, but the steel strip in this system is both the carrier of water-soluble film formation and the power rotating device. The design of this link is very important.
