Wellson breathable film production line applies a special bimetallic screw extrusion control system. By optimizing the design of the flow channel, it can better improve the melt flow rate and the plasticizing effect of the raw material, and meet the special extrusion requirements of the resin raw material. By adopting the world-class pendant hanger-type runner design, the fully automatic die head and the high-precision automatic thickness detection and control system can more effectively track and control the horizontal and vertical thickness uniformity of the film, thereby ensuring its high quality. This is critical to ensure subsequent processing and problem-free stretching of the film.
The fully automatic high-speed winding device avoids the defects of the traditional winding method. The professionally designed tracking contact roller keeps the roll film in a good rolling posture even when it is turned at high speed; the rotation of the turning frame adopts the frequency conversion control method, which can realize the slow start and stop of the equipment, improve the stopping accuracy, and make the winding tension more stable : The tension setting method of any dimension can ensure constant torque winding, effectively prevent the shrinking phenomenon of the roll film during the winding process, and obtain a neat winding effect: The online automatic speed adjustment swing design can reduce the cumulative error of winding, Improve the flatness of the film roll.
