A kind of self-adhesive label production gluing device and gluing process

Abstract

The invention provides a self-adhesive label production gluing device and a gluing process, including an installation base plate, a supporting foot, a conveying mechanism, a gluing mechanism and a positioning mechanism. Stable support and tightening of flexible self-adhesive labels reduces the uniformity of glue spraying and subsequent combination with film rolls, and it is difficult to quickly install and disassemble self-adhesive label paper. The sprayed glue is evenly scraped and flattened, and it is difficult to squeeze the joint between the label paper and the film roll stably and evenly, which increases the accumulation of glue and causes a gap between the self-adhesive label and the film roll. The probability of wrinkling and deformation makes it more difficult to carry out continuous equidistant cutting operations on label paper, which reduces the efficiency of label paper gluing and the convenience of label paper in the subsequent use process.

Description

technical field [0001] The invention relates to the technical field of self-adhesive label production, in particular to a self-adhesive label production gluing device and gluing process. Background technique [0002] Compared with traditional labels, self-adhesive labels have the advantages of no need to brush glue, no paste, no need to dip in water, no pollution, and save labeling time. They have a wide range of applications and are convenient and quick. Self-adhesive is a material, also called self-adhesive label material. It is a composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. After printing, die-cutting, etc. As a finished label, the following problems often occur during the self-adhesive label adhesive spraying operation: [0003] 1. During the gluing operation of self-adhesive labels, it is difficult to stably support and tighten the self-adhesive labels of fl...

Problems solved by technology

[0003] 1. During the gluing operation of self-adhesive labels, it is difficult to stably support and tighten the self-adhesive labels of flexible materials, which increases the probability of synchronous vibration of self-adhesive labels caused by mechanical vibration and reduces the glue spraying The uniformity of the self-adhesive label paper and the combined effect between the follow-up and the film material roll, and it is difficult to realize the rapid installation and disassembly of the self-adhesive label paper, which reduces the working efficiency of the self-adhesive label paper gluing and conveying operation, and it is even more difficult to realize the label paper and The synchronous unwinding of film rolls increases the probability of wrinkling or breakage caused by excessive stretching of label paper or film rolls

[0004] 2. In the process of gluing self-adhesive labels, due to the poor fluidity of the glue, it is difficult to evenly scrape and spread the sprayed glue, and it is difficult to clean the bonding parts of the label paper and the film roll. Stable and uniform extrusion increases the probability of wrinkles and deformations between the self-adhesive label and the film roll caused by the accumulation of glue, making it more difficult to carry out continuous equidistant cutting of the label paper, reducing the glue application of the label paper Efficiency and easy access to label stock during subsequent use
