Die cutting and labeling unit of bottom-paper-free non-dry sticker labeling machine and labeling method of die cutting and labeling unit

Abstract

The invention discloses a die cutting and labeling unit of a bottom-paper-free non-dry sticker labeling machine. The die cutting and labeling unit comprises a die cutting linear movement pair, a labeling linear movement pair and a mechanical arm. The die cutting linear movement pair is connected with the labeling linear movement pair. The mechanical arm is connected with the labeling linear movement pair and can be driven by the labeling linear movement pair to linearly reciprocate so as to get close to or away from the die cutting linear movement pair. The invention further discloses a labeling method of the die cutting and labeling unit of the bottom-paper-free non-dry sticker labeling machine. The mechanical arm is innovatively used in the bottom-paper-free non-dry sticker labeling machine, the punching effect can be achieved in the die cutting process, and therefore only one layer of label paper is needed for a non-dry sticker label used by the bottom-paper-free non-dry sticker labeling machine, bottom paper does not need to be used, and the problem that because non-dry sticker labels used by non-dry sticker labeling machines in the prior art must be provided with bottom paper, resource waste and environment pollution are caused is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a die-cutting and labeling unit of a bottomless paper self-adhesive labeling machine, and the invention also relates to a die-cutting and labeling unit of the bottomless paper self-adhesive labeling machine label method. Background technique [0002] At present, the self-adhesive labels used by the existing self-adhesive labeling machines need to be made with two layers of paper: one layer is the label paper, one side is the printing surface, which is used to print the label pattern, and the other side is the non-printing surface. It is coated with self-adhesive; the other layer is a backing paper coated with a release agent (silicone oil), which is used to isolate the self-adhesive coated on the non-printing surface of the label, so that the rolled label is free from sticking, and at the same time sticking and fixed die-cut formed labels. The disadvanta...

Problems solved by technology

[0003] The purpose of the present invention is to provide a die-cut labeling unit of a self-adhesive labeling machine without a backing paper. The self-adhesive labels used by the self-adhesive labeling machine must have a backing paper, which causes waste of resources and environmental pollution.
