A kind of bottomless paper labeling method and bottomless paper labeling machine

Abstract

The invention discloses a labeling method for a label without backing paper and a labeling machine for a label without backing paper. The labeling method comprises the following steps of: gluing the bottom surface of a label without backing paper by using a primer spreading device; cutting off the glued label without backing paper by using a dynamic wheel rotary single-piece cutting-off mechanismarranged behind a label without backing paper trademark traction machine; feeding the cut label below a label pressing-in roller arranged behind the dynamic wheel rotary single-piece cutting-off mechanism by using the dynamic wheel rotary single-piece cutting-off mechanism;and attaching the label to the surface of an attached article by using the label pressing-in roller. According to the labeling machine for the label without backing paper disclosed by the invention, because a label transfer mechanism for transferring the separated label in the traditional labeling machine is omitted, the label directly enters between the attached article and the label pressing-in roller by directly utilizing the inertia trend of the label separated from the label without backing paper at a steering roller and is attached to the attached article by using the label pressing-in roller. Therefore, the invention has the advantages of simple structure and low fault rate and provides possibility for practicability of the labeling machine for the label without backing paper.

Description

technical field [0001] The invention relates to a bottomless paper labeling method and a bottomless paper labeling machine. Background technique [0002] The existing self-adhesive labels with backing paper have a paper utilization rate of less than 50% due to the presence of backing paper. And the bottomless label, because it does not have the bottom paper used as the label carrier, therefore, the utilization rate of the paper of the label can be increased by at least 50%. Therefore, the future self-adhesive labels will definitely develop in the direction of linerless paper. At present, the application of linerless labels is mainly reflected in two aspects. The production of a bottomless label, because the linerless label has no bottom Therefore, the printing method is different from the conventional printing, which is a problem; the second is the labeling of the linerless label, because the linerless label has no liner and no traction by the liner, therefore, the linerles...

Problems solved by technology

[0002] The existing self-adhesive labels with backing paper, due to the existence of backing paper, the paper utilization rate of the label is less than 50%

[0005] The technologies disclosed in the above two patent documents are applicable to the labeling of linerless labels, but there is a common problem in the technologies disclosed in the above two patent documents, that is, when the label is removed from the linerless label After separation, a relevant transfer mechanism is required to transfer and attach the separated label to the object to be attached

The transfer mechanism adopted in the Chinese patent document CN2853627 is a transfer composite mechanism composed of a transfer medium and its circulating conveying device, and is connected with the die-cutting bottom roller of the die-cutting mechanism through the transfer medium, and the bottomless paper label is die-cut and formed. It is transferred on the transfer medium, and then the formed label is peeled off by the label peeling and bonding mechanism and pasted on the object to be pasted. This mechanism is not only complicated, but also difficult to control the position of the label during the transfer of the trademark; China The patent document CN101209760 uses a rotating vacuum drum to transfer and attach labels. This rotating vacuum drum has both a vacuum part and a positive pressure part. It needs vacuum adsorption and positive pressure release to work alternately during the work process. , which makes the structure of this rotary vacuum drum very complicated, and its stability is not high, and the problem of missing labels often occurs, so it is very difficult to promote this kind of bottomless paper labeling machine

Due to the above problems, the linerless labeling machine has not fully reached the practical standard for so many years
