Preparation method of anti-counterfeiting self-adhesive label

Abstract

The invention relates to a preparation method of an anti-counterfeiting self-adhesive label. Manufacturing of the anti-counterfeiting self-adhesive label is completed through cooperation of a bottom plate, a feeding device, a fixing plate, a gluing device, a laminating device, a glue scraping device and a winding device. According to the preparation method of the anti-counterfeiting self-adhesivelabel, the problems that when an existing anti-counterfeiting self-adhesive label manufacturing device is used for manufacturing the anti-counterfeiting self-adhesive label, surface paper is directlycoated with glue, and the existing device does not tension backing paper, as a result, wrinkles are generated on the backing paper, redundant glue exists in the wrinkles, the manufacturing of the anti-counterfeiting self-adhesive label is unqualified due to wrinkles generated when the surface paper and the backing paper are attached, the surface paper and the backing paper are directly rolled up after being attached, the attached surface paper and backing paper are not pressed, as a result, the surface paper and the backing paper are incompletely attached, glue on the side edges of the attached surface paper and backing paper is not scraped off, and a large amount of glue is wasted are solved.

Description

technical field [0001] The invention relates to the technical field of making anti-counterfeiting self-adhesive labels, in particular to a method for preparing anti-counterfeiting self-adhesive labels. Background technique [0002] Self-adhesive labels have the advantages of no need to brush glue, no need to dip in water, no pollution, save labeling time, etc., and have a wide range of applications and are convenient and fast. Self-adhesive is a material, also known as self-adhesive label material, which 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. And after printing, die-cutting and other processing to become the finished label. The face paper generally uses paper, film or other special materials as the fabric, and the face paper is glued to the surface of the non-stick base paper with a surface. The base paper has an isolation effect on the adhesive, so it...

Problems solved by technology

[0004] (1) When the existing anti-counterfeiting self-adhesive label production equipment is making anti-counterfeiting self-adhesive labels, it usually directly smears glue on the face paper. Since the existing equipment does not tension the backing paper, the surface of the backing paper Wrinkles are generated, resulting in excess glue in the folds when applying glue, and at the same time causing wrinkles when the top paper and bottom paper are attached, resulting in unqualified production of anti-counterfeit self-adhesive labels;

[0005] (2) When the existing anti-counterfeit self-adhesive label production equipment is making the anti-counterfeit self-adhesive label, it is directly rolled up after the face paper and the bottom paper are pasted, and there is no need for the pasted top paper and bottom paper. The paper is pressed together, resulting in incomplete bonding between the top paper and the bottom paper, and the glue on the side after the two are pasted is not scraped off and collected, thus wasting a lot of glue
