Cigarette pack box gluing and folding device

Abstract

The invention discloses a gluing and folding device for a cigarette pack box. The cold glue spraying device first sprays a row of cold glue dots on the left to-be-folded surface and the right-to-be-folded surface of the cigarette pack box to be processed, and then sprays the glue through hot melt glue. The device sprays a row of hot glue dots on the left side of the main body and the right side of the main body of the cigarette pack to be processed, and then uses the movable folding device to complete the final folding and pasting of the to-be-processed cigarette pack to form a finished cigarette pack. The cigarette pack box gluing and folding device of the invention can meet the gluing and folding requirements of cigarette pack boxes of different specifications, and improve the bonding effect of the cigarette pack boxes.

Description

technical field [0001] The invention relates to tobacco packaging machinery, in particular to a cigarette pack box gluing and folding device. Background technique [0002] In the existing automated tobacco packaging production line, when the cigarette pack moves in a straight line in the channel, it involves the gluing and folding positions of the cigarette pack carton. The sides are glued, and the folding of the two sides of the cigarette pack carton is completed by the subsequent fixed folder. But there are several problems in actual production: [0003] (1) When the specifications of the cigarette pack carton are changed, a large number of special parts for the gluing part need to be redesigned and replaced; [0004] (2) For the carton specifications of medium and fine branches, the gluing method of the rubber roller is more difficult to bond the narrow side, and the viscosity of the glue is required to be large, otherwise the glue will be easily thrown at high speed; ...

AI Technical Summary

Problems solved by technology

[0005] (3) The glue in the open glue tank is easy to form a skin, which affects the gluing effect;

[0006] (4) The fixed folder is easily contaminated by glue and needs to be cleaned frequently

[0007] In addition, at room temperature, cold glue can provide sufficient adhesion for the adhesive surface of the cigarette pack carton, but requires a long drying time, which makes the cigarette packs need to go through a longer path on the machine, or Set up heating channels on the machine to shorten the drying time, which leads to more complex and longer size of the machine equipment

The use of hot melt adhesive can quickly bond and fix the cigarette pack carton, but the subsequent folding needs to be completed as soon as possible to avoid affecting the bonding effect of the hot melt adhesive

[0008] Moreover, as tobacco packaging equipment becomes more and more intelligent, it is often required that the equipment can be modularized according to function and process, quickly change specifications, and even change the form to adapt to the new process. It is difficult to achieve these requirements in a way
