AI Technical Summary
Existing plastic film winding devices are prone to displacement of the screw and threaded sleeve due to vibration during use, and the distance between the rotating roller and the winding roller cannot be adjusted, resulting in loosening of the film roll edges or dispersion of tension, which affects the tightness of winding.
The design incorporates a sliding frame, a drive assembly, a limiting assembly, and a cutting blade. The drive assembly rotates the rotating roller and slides the sliding frame. The limiting assembly adjusts the position of the sliding ring to ensure concentrated tension in the plastic film and a fixed position for quantitative winding.
It enables tight winding of plastic films of different widths, avoiding problems such as loose edges and curling of the film roll. The operation is simple and the winding effect is stable.
