Manufacturing method of self-adhesive label

Abstract

The invention provides a manufacturing method of a self-adhesive label. The manufacturing method is implemented by matching a frame body, a tightening type gluing device, two pressing devices, a backing paper collecting roller, a base material collecting roller, an electric roller and wiping cotton. The manufacturing method can solve the problems that in a traditional compounding process, an adhesive is difficult to be uniformly smeared on the back surface of a base material by manual brushing, dust is likely to be attached to the back face of the base material along with the adhesive, workers easily suffer from sour and numb feeling during manual brushing, and manual brushing is not suitable for long-time assembly line production; and when the base material and backing paper are being pressed after the adhesive is brushed, pressing is generally conducted in the mode that an upper die and a lower die get close to each other to realize direct pressing, and the pressing mode easily causes scattered extrusion of the adhesive in the pressing area and leads to the situation that the compounded self-adhesive label is separated for the second time under the extrusion of redundant adhesive.

Description

technical field [0001] The invention relates to the technical field of making self-adhesive labels, in particular to a method for making self-adhesive labels. 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 kind of material, also called self-adhesive label material. It is a composite material with the substrate as the fabric, the back is coated with adhesive, and the silicon-coated protective paper is the backing paper. It is processed by printing, die-cutting, etc. Finished label. [0003] When the traditional substrate and backing paper are combined, the adhesive is usually painted on the back of the substrate manually. However, manual brushing is difficult to ensure that the adhesive can be evenly applied to the back of the substra...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a method for making self-adhesive labels, which can solve the problem that in the traditional compounding process, manual brushing is difficult to ensure that the adhesive can be evenly applied to the back of the substrate, and some dust may adhere to the back of the substrate along with the adhesive. On the back of the base material, at the same time, manual brushing is prone to tingling, which is not suitable for long-term assembly line production. When the base material and the backing paper are pressed after the adhesive is painted, the upper and lower molds are usually pressed together and pressed directly. This kind of pressing method is easy to cause the glue in the pressing area to be squeezed out in all directions, resulting in the secondary separation of the previously compounded self-adhesive labels under the extrusion of excess glue.
