AI Technical Summary
Packaging films are prone to problems such as unevenness and wrinkles, overlapping and deformation of the layers, static electricity adhesion, and uneven roll diameter during the winding process, resulting in poor winding effect and unevenness.
The packaging film biaxial winding machine uses components such as guide plates, hydraulic rods and film-passing rollers to adjust the tension between the rollers. Combined with rollers with adjustable diameter and clamping plates, it can achieve constant tension on the plastic film and adapt to the winding of rolls with different diameters.
This effectively avoids wrinkles and electrostatic adhesion of the film tape before winding, ensuring the flatness of the winding and the uniformity of the roll diameter, thus improving the winding effect.
