[0002] The rewinding process is a crucial step in the slitting machine's operation. The rewinding roller typically requires a plastic core ring to neatly and orderly rewind the slit material. However, in practice, accurately placing the plastic core ring on the rewinding roller and quickly aligning it into the correct position present numerous challenges.

[0003] The traditional approach is to rely on manual labor to align the plastic core ring with the winding roller. The operator needs to spend a lot of time and energy to adjust the position of the core ring to ensure that it coincides with the axis of the winding roller and is in a suitable axial position. When the plastic core ring is aligned and installed on the winding roller, there are often problems such as inconvenient operation, low alignment efficiency and unstable fixation, which affects the overall working efficiency and winding quality of the slitting machine. Therefore, we propose a quick alignment device for the plastic core ring of the winding roller of the slitting machine to solve the above problems. Utility Model Content
