AI Technical Summary
Technical Problem
During the winding process of existing film slitting equipment, air can easily get into the interlayer of the film, causing streaks in the product and affecting its quality.
Method used
The film is flattened and tightly adhered by a biaxially oriented film slitting and winding degassing roller. Through the flattening and degassing components and scraper structure, and the threaded connection of the biaxial screw and lead screw, the film is flattened and tightly adhered. Combined with motor drive, interlayer air is expelled to avoid wrinkle formation.
Benefits of technology
It effectively eliminates air between film layers, prevents the formation of streaks, and improves product quality.
