AI Technical Summary
In the existing technology, during the film winding process, the thickness deviation of the inner core causes the pressure roller to be unable to effectively press, resulting in wrinkles and affecting the winding quality.
Several eccentric wheels are used to correspond to the inner core. The film is pressed by rotating under the action of gravity. When the position of the limit ring needs to be adjusted, the clamping block is released by the drive rod, so as to realize the flexible adjustment of the position of the inner core.
It effectively reduces wrinkles during film winding, improves winding quality, and facilitates adjustment of the core position.
