[0002] Labels are the first source of information about products that people come into contact with, and are the most direct way for consumers to understand product information. Labeling products can not only introduce product features in more detail, but the application of labels has also expanded from the original product packaging to the printing of express orders and delivery orders, and has penetrated into all aspects of people's lives. Paper labels are generally printed on a large area during the production process. After printing is completed, the paper labels need to be cut to form labels that meet standard specifications. However, most paper labels are rolled together. When cutting, the label paper roll needs to be placed on the paper roller. Because the label paper roll is large in size and heavy in weight, it is inconvenient to place it on the paper roller with the assistance of a machine, and it is inconvenient to adjust the position and fix it, resulting in the paper label being cut. The cutting accuracy is greatly affected. Therefore, a new label roll positioning device is designed to change the above technical defects. Utility Model Content
