Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing equipment technology, and in particular to a glue-applying device and method for cigarette rolling machines. Background Technology

[0002] A cigarette rolling machine is a machine that rolls tobacco into cigarettes using cigarette paper; it is the main type of cigarette rolling machinery. It first rolls the cigarette paper into an empty tube, and then fills it with tobacco.

[0003] In the current cigarette production process, the existing cigarette machine glue control and coating assembly includes a frame, a coating roller, a control roller, and a glue cylinder. The coating roller is fixed to the frame by bearings, the glue cylinder is suspended on the support rod of the frame, and the control roller is installed at the opening of the glue cylinder by bearings.

[0004] Chinese patent CN107930986A discloses a self-flowing glue-applying device for a cigarette machine, comprising a control box, a frame, a glue bucket, a glue hose, and a glue-applying head. The glue bucket includes a cylindrical section and a frustum-shaped section. A rotating sleeve is movably fitted inside the cylindrical section. A first motor is mounted on the frame, and its output shaft is fitted with a first gear. A matching second gear is fitted on the upper end of the rotating sleeve. Above the glue bucket, the frame has vertically extending guide posts. A push rod passes through the guide posts, and the upper end of the push rod has a first magnet block. The push rod extends downward into the glue bucket and is connected to a pressure plate. The frame also has a second motor, and its output shaft extends laterally above the guide posts and is fitted with a rotating disk. The rotating disk has a plurality of magnet seats along its circumference, and each magnet seat has a second magnet block that matches the first magnet block. The push rod can slide up and down along a guide channel through the magnetic interaction between the first magnet block and one of the second magnet blocks. This structure can improve the self-flowing speed of the adhesive coating and is highly efficient. Although the above solution has many beneficial effects, it is difficult to ensure the uniformity of the adhesive coating when applying it to cigarette paper, thus affecting the processing quality of the cigarettes.
