[0002] Hot melt adhesive labeling machine can be used for full-circle labeling and is widely used in the labeling of bottles such as mineral water bottles. The existing labeling machine places the bottom end of the glue coating roller inside the sol pool. The glue coating roller continuously dips the glue in the sol pool during the rotation process, and then scrapes it evenly with a glue scraper.

[0003] However, during the production process, the liquid level of the glue in the sol pool changes continuously with use, resulting in a constant change in the position of the glue coating roller immersed in the glue. If the glue coating roller is placed too far inside the glue, it will result in too much glue dipping. If the glue coating roller is placed too far inside the glue, it will result in too little glue dipping, which will affect the gluing effect. Summary of the invention
