Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco packaging, in particular to a self-cleaning device of a box sealing and labeling machine for cleaning label paper and printed labels. Background Art
[0002] Label printing is a common process in cigarette packaging, usually printed by the coding and labeling machine in the carton filling and sealing machine. The main process is: the cigarette box is transported close to the labeling machine, triggering the photoelectric switch, controlling the operation of the labeling machine, driving the output of label paper and carbon ribbon, so that the label paper and carbon ribbon pass through the labeling machine's print head at the same speed with the label paper at the bottom and the carbon ribbon at the top, and the label is printed using the thermal transfer effect of the print head.
[0003] The print head is a component in coding and labeling machines that has high requirements for its operating environment and is prone to wear. To ensure a clean operating environment, a protective cover is typically installed on the print head to isolate it from the high-dust environment of the production site. However, in actual production, large dust particles in the production site can easily adhere to the label paper during cleaning processes, enter the dust cover with the label paper, and reach the bottom of the print head, causing scratches on the print head and significantly shortening its lifespan. In fact, print heads with a theoretical lifespan of three to four months can begin to malfunction frequently after just one month of use. This not only significantly increases production maintenance costs but also affects print quality and the smooth operation of production. Utility Model Content
