Palm-joint glue spreading method and device of film label

Abstract

The invention discloses palm-joint glue spreading method and device of a film label. The method comprises the following step of printing glue on one end of the film label along the edge by a printing technology. The device comprises a palm-joint machine conveying the film label and also comprises a forme roller and an impression roller which clamp the film label, wherein the glue is printed on one end of the film label along the edge by the forme roller. The palm-joint glue spreading method and device of the film label have the advantages that the glue-spreading amount is stable, the rejection rate of the film label is reduced and the glue and the film material are saved.

Description

technical field [0001] The invention belongs to the technical field of film labels, and in particular relates to the technique of clapping palms for film labels, in particular to a method and device for clasping palms for film labels. Background technique [0002] Before the film label is attached to the bottle body, the two ends of the film label need to be butted and glued together. This process is called the joining of the film label. In the gassing process of film labels, it is necessary to first apply glue 001 on one end of the film label 002 along the edge direction, such as figure 1 shown. [0003] In the gas palm gluing method and device of existing film label, such as figure 2 As shown, the glue tank 100 is used to fill the glue 001, and then lead to the top of the film label 002 through the hose 200 and the copper tube 300. There is a wool felt 400 at the lower end of the copper tube 300, and the wool felt 400 is in contact with the film label 002. The label 00...

AI Technical Summary

Problems solved by technology

This gluing method and device is applied on the film label 002 through the wool felt 400, and the amount of glue applied is related to the relative speed of the film label 002 relative to the wool felt 400, that is, the operating speed of the hand-joining machine 500, and the hand-joining machine 500 is fast. , the amount of glue applied to the wool felt 400 is small, the speed of the palm machine 500 is slow, and the amount of glue applied to the wool felt 400 is large, which leads to the amount of glue applied not very stable

And we know that the wool felt 400 cannot always match the running speed of the gassing machine 500, especially in the process of gluing the head and tail of the film label 002 (that is, in the process of accelerating or decelerating or starting or stopping the gassing machine 500), The running speed of the Gassho machine 500 is not very stable, which leads to the fact that the film label 002 of the final gassed palm is easy to be unglued due to insufficient glue application, or the film label is melted due to too much glue application. Therefore, the existing film label glue application method and device will cause Greater than 10% film label waste

[0004] In addition, in order to ensure that the film label has sufficient and stable adhesion when the palms are folded together, the glue width applied on the film label 002 by wool felt 400 needs to reach 3.5-4mm, which in turn leads to a large amount of glue and a large consumption of film

[0005] In short, the existing film label gluing method and device have the shortcomings of unstable glue application, high scrap rate of film labels and serious waste of glue and film materials.
