Description

Label attaching device and label printing and attaching machine

Technical Field

The present invention relates to the field of label technology, in particular to a label attaching device and a label printing and attaching machine.

Background Art

The label rolls on the market all include a strip-shaped base film and a number of label papers arranged at equal intervals on the base film. Currently, there are two methods for printing and attaching color labels:

The first is the automatic method. After a color inkjet printer prints a number of labels, the label stripping mechanism strips the label paper and the base film to achieve continuous automatic printing and label removal. However, the base film cannot be cut during the process. Therefore, real-time printing cannot be achieved, that is, a label cannot be attached after printing. When the label content or the required label color needs to be changed, it is necessary to discard the printed label, reprint the currently required label, and rewind the label paper onto the label stripping machine, resulting in waste of labels and increased labor costs.

The second is the manual method, in which a color inkjet printer prints out a label and then the label is manually taken and attached to the product. The required content can be printed in real time according to demand. However, since the label paper is thin, easily deformed and has adhesive on one side, it is difficult to manually attach the label evenly to the product.
