AI Technical Summary
In existing waterproof membrane extrusion molding equipment, materials tend to adhere to the rollers, resulting in uneven thickness on the roller surface, creating periodic pits or indentations, which affects the quality of the finished product.
The scraper mechanism and scraper strips work together to scrape off the material on the outer side of the first pressure roller, and the material viscosity is reduced by a combination of air-cooled box and water-cooled box cooling mechanism to prevent material adhesion.
It effectively reduces material residue on the rollers, improves finished product quality, and ensures uniformity of the roll surface and forming effect.
