AI Technical Summary
In existing production processes, electrostatic films are prone to wrinkles and shifts during unwinding, conveying, and rewinding due to uneven tension, release of internal material stress, or external interference, which affects the quality and production efficiency of antistatic vacuum bags, especially lacking dynamic adaptive adjustment capabilities under high-speed continuous production conditions.
An electrostatic film leveling device for making antistatic vacuum bags is adopted, including a base, guide roller, leveling mechanism and smoothing roller. The leveling mechanism, which consists of a telescopic rod driven by a reciprocating cylinder and a smoothing roller, achieves dynamic leveling and straightening. By using the cooperation of spring and return spring, the leveling angle and pressure are adaptively adjusted to avoid excessive stretching or damage to the functional coating.
It effectively eliminates wrinkles and shifts caused by uneven tension and internal stress release during the production process, improves the flatness and consistency of the membrane surface, enhances the quality and production efficiency of antistatic vacuum bags, and operates stably with good compatibility with existing production lines.
