Description

Technical Field

[0001] The utility model relates to a glue coating device, belonging to the technical field of glue coating mechanical equipment. Background Art

[0002] In the production process of cigarette filter rods, it is necessary to apply glue to the middle line and the seal of the formed packaging paper tape first, and then use the packaging paper to wrap the filter material, and then perform seal plastic shaping and cutting to obtain filter rods of a set length. After retrieval, it is found that a Chinese patent with the publication number CN205555699U discloses a glue adding device for the middle line of cigarette filters. In this patent, through the rotation of the glue supply roller and the glue control roller, the glue supply roller evenly applies glue to the forming paper, the glue control roller sucks the glue from the glue cylinder, and transfers the glue to the forming paper through rotation. There is a gap between the groove in the middle of the surface of the glue control roller and the glue supply roller, so that the glue is extruded when passing through the glue control roller, forming a uniform glue line. However, there is no constraint on the distance between the glue control roller and the glue supply roller in this patent, and it is impossible to control the thickness of the glue line. When the glue control roller is misaligned, it is necessary to stop the machine for correction, resulting in a reduction in production efficiency. Summary of the Invention
