Description

Deviation correcting device for automatic detection of self-adhesive labels Technical Field The utility model relates to the technical field of self-adhesive labels, in particular to a deviation correcting device for automatic detection of a self-adhesive label. Background In the production links of printing, die cutting, detecting and the like, the self-adhesive labels (self-adhesive labels and pressure-sensitive labels) are usually required to be continuously transported by a conveying device so as to carry out visual detection (such as printing defects, die cutting deviation, stains and the like). According to the disclosed visual detection device (bulletin number: CN 218726739U) for label paper production, through forward rotation or reverse rotation of the handle in the above application, the two movable rollers can move close to each other or move far away from each other, so that the label paper can be in a tight state, and the collection position of the label paper can be ensured to continuously move horizontally. However, in the above application, the label may shift laterally due to factors such as uneven tension, installation error of the guide roller, or deformation of the material during the transmission process, and simply tightening the label may not automatically correct the shift, resulting in deviation of the detection area from the predetermined position, and affecting the detection accuracy.
