AI Technical Summary
Existing digital printing machines require manual cutting of the printing paper when removing the paper roll, which increases the difficulty of operation, affects the appearance, and reduces work efficiency.
An automatic winding device including a tension adjustment component and a cutting component was designed. The paper is guided by a guide roller, kept taut by the tension adjustment component, and cut simultaneously cuts the top and bottom sides of the printing paper in one go by the cutting component to ensure the flatness of the cut.
It improves the quality and appearance of paper winding, reduces the difficulty of operation, and enhances the working efficiency of digital printing machines.
