Anti-counterfeiting self-adhesive label coating system and coating treatment method

Abstract

The invention relates to an anti-counterfeiting self-adhesive label coating system and a coating treatment method. The anti-counterfeiting self-adhesive label coating system comprises a base, a tightening frame, a coating device, a cooling frame, a pressing device, a sleeving set and a winding set, wherein the coating device is mounted in the middle of the base; the sleeving set is mounted at theleft end of the base; the tensioning frame is arranged between the sleeving set and the coating device and mounted on the base; the winding set is mounted at the right end of the base; the cooling frame is arranged between the winding set and the coating device and mounted on the base; and the pressing device is arranged on the left side of the cooling frame. Through the anti-counterfeiting self-adhesive label coating system and the coating treatment method, the problems that the surface of a commonly-used coating roll is cold, a hot melt adhesive adhering to the surface of the coating roll may directly solidify on the surface of a roll body at low temperature, the adhesion force between the hot melt adhesive and the coating roll is large in the coating process, much hot melt adhesive is difficult to be transferred to the surfaces of labels, and remaining hot melt adhesive not processed in time directly solidifies on the roll body can be solved.

Description

technical field [0001] The invention relates to the technical field of self-adhesive label processing, in particular to an anti-counterfeit self-adhesive label coating system and a coating treatment method. 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 fast. Labels are processed by glue hot melt adhesive coating. The traditional coating method usually coats the labels through the coating roller set under the label. However, the traditional coating roller often encounters some problems when used: [0003] 1. The surface of the commonly used coating roller is relatively cold, and the hot melt adhesive adhering to the surface of the coating roller may be directly solidified on the surface of the roller body due to the low temperature, and when coating, due to th...

Problems solved by technology

[0006] The present invention can solve the problem that the surface of commonly used coating rollers is relatively cold, and the hot melt adhesive adhering to the surface of the coating roller may be directly solidified on the surface of the roller body due to the low temperature. The inter-adhesive force is relatively large, which makes it difficult to transfer more hot melt adhesive to the surface of the label, and the residual hot melt adhesive left on the surface of the roller body is directly solidified on the roller body after not being processed in time, thereby increasing the friction of the roller body. The thickness of the surface will affect the subsequent coating process. The label may relax during the conveying process, causing the label to wrinkle, which will easily lead to problems such as over-coating or uncoating when the coating roller coats the label.
