AI Technical Summary
When winding small or intermittent rolls, existing winding machines cannot tightly press the drive rollers and driven rollers together, causing the rolls to slip and skew, which affects the quality and dimensional accuracy of the rolls.
It adopts a segmented roller structure. Through the cooperation of slider and guide rail, the connecting block and passive roller are pushed by cylinder to realize the segmented adjustment and fixation of passive roller, so as to ensure that it can adapt to roll materials of different widths.
It enables precise adjustment of roll materials of different widths, improves winding accuracy and roll material quality, and avoids slippage and skewing.
