Electronic tag gluing mechanism and coating module

Abstract

The invention discloses an electronic tag gluing mechanism and a coating module. The electronic tag gluing mechanism comprises a gluing support, a first gluing apparatus, a second gluing apparatus anda glue storage apparatus, wherein the first gluing apparatus, the second gluing apparatus and the glue storage apparatus are separately arranged on the gluing support; the first gluing apparatus comprises a first gluing roller, a first viscose glue roller and a first glue storage hopper, the first glue storage hopper is arranged on the gluing support, the first glue storage hopper is provided with a first storage groove, two ends of the first viscose glue roller are respectively arranged on the inner side wall of the first storage groove, and the first gluing roller is arranged on the gluingsupport. A bottom material is twice glued, so that all the bottom material can be ensured to be coated with glue, the problem of incomplete lamination since the single gluing roller is lack of glue and cannot smear the glue onto the bottom material can be avoided, and the situation of bubbles when the bottom material and a surface material of an electronic tag are laminated can be avoided.

Description

technical field [0001] The invention relates to the field of coating machines, in particular to an electronic label glue coating mechanism and a coating module. Background technique [0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. The brush coater is the oldest coating module, originally used in the 1850s for the production of coated wall wallpapers using china clay paints. There are 3 different types of brush applicators: round brush applicators, blanket roller applicators and blanket jacket applicators. The first blade coater patents appeared in the 1950s. Since then, knife coater technology has developed rapidly. According to the different feeding equipment, scraper type and scraper installation position, the scraper coating head is also divided into many types, such as hard...

AI Technical Summary

Problems solved by technology

[0003] Yet in existing coating machine, all be provided with the gluing device that gluing is carried out to substrate, but, in the process of gluing, because substrate is to realize gluing at the moment of contacting with gluing roller , it is necessary to ensure that there must be glue on the roller. Once there is too little glue on the glue roller, the substrate may not be coated with glue, so that there will be incomplete fit when laminating. problems, which in turn causes air bubbles to appear in the electronic label, which reduces the quality of the produced electronic label, reduces the yield rate of the electronic label, and increases the cost of production
