AI Technical Summary
Existing wet-laid nonwoven fabric substrates for water treatment membranes are prone to wrinkles and folds during the winding process, resulting in low production efficiency. Furthermore, traditional winding devices struggle to control pressure uniformity, affecting substrate quality.
The winding device, which uses screw control and hydraulic arm coordination, ensures stable pressure on the nonwoven substrate during winding by adaptively adjusting the moving speed and tension of the winding shaft, thus preventing air from getting trapped. The device also uses a rotating screw and a proximity roller to achieve adaptive tension control.
It achieves flat winding of nonwoven fabric substrate, reduces wrinkles and creases, improves production efficiency and substrate quality, and reduces scrap rate.
