[0004] This utility model can limit and stretch the label paper when it moves through the limiting roller. Through the rotating rod, convex rod, ball and elastic component, it is convenient to preliminarily position-limit label cylinders of different sizes, so that label cylinders of different sizes are kept in the middle of the rotating rod. Then, through the cooperation of the arc-shaped groove, annular groove and limiting component, it is convenient to perform secondary position-limiting on label cylinders of different sizes, avoiding the position movement of the label cylinder and causing the position misalignment of the label paper when labeling the product. However, in the actual use process, when the material is limited by two limiting columns, if the distance between them cannot be adjusted flexibly, the material is very likely to have different ductility due to different conditions such as length, and there is a possibility of breaking exceeding the threshold. For this reason, we propose a stretching relief device for labeling materials. Content of the Utility Model
