Description

Technical Field

[0001] The utility model relates to a self-adhesive label die-cutting device, belonging to the technical field of self-adhesive labels. Background Art

[0002] In the process of making self-adhesive labels, in addition to printing, the die-cutting process is also very important. The so-called die-cutting is the process of using a knife plate to cut the self-adhesive material into the required shape. Most die-cutting processes are to half-cut the self-adhesive material, that is, only cut through the surface layer and glue of the self-adhesive material without cutting the bottom paper. In most cases, after the self-adhesive material is die-cut into shape, the unnecessary surface layer and glue will be discarded and the required part will be left.

[0003] In actual production, the phenomenon of "flying marks" often occurs. There are many reasons for the occurrence of "flying marks" and the breakage of the waste discharge edge, but it is usually necessary to adjust the diameter of the waste discharge roller. However, adjusting the diameter of the waste discharge roller requires stopping the machine to replace the waste discharge roller, which is time-consuming and labor-intensive, affecting the production efficiency of the enterprise;

[0004] At present, in order to deal with the change in the waste discharge angle caused by the increased diameter of the waste discharge roller, the problem is generally solved by adjusting the up and down position of the adjusting roller, such as a self-adhesive label die-cutting device with application number 202022015702.0. However, after the diameter of the waste discharge roller increases, the tangent point between the waste edge and the waste discharge roller not only changes in the longitudinal coordinate, but also in the transverse coordinate. If the waste discharge angle is synchronized only by adjusting the up and down position of the adjusting roller, it may not meet the adjustment needs in most cases, and there will still be a risk of flying marks. It can be seen that in order to solve this technical problem, a self-adhesive label die-cutting device is urgently needed. Utility Model Content
