[0002] To meet the customized needs of customers, finished self-adhesive labels need to be slit before rewinding, and rewinding is performed after slitting to the set width. Traditional slitting equipment often places the slitting blades on the same roller or shaft for axial position adjustment. Because the slitting blades are equipped with components for connection and adjustment, the spacing between adjacent slitting blades cannot be adjusted to a very small distance due to interference from the components. This makes it impossible to slit self-adhesive labels of extremely small widths, limiting the use of the equipment and resulting in poor overall performance. Accordingly, the present utility model proposes a slitting device for the production of self-adhesive labels. Utility Model Content
