Description

Technical Field

[0001] The utility model relates to the technical field of sealing detection, in particular to a cigarette package sealing detection device. Background Art

[0002] In order to facilitate storage and transportation and reduce and avoid damage and mildew caused by environmental factors, a layer of transparent film is coated on the outer packaging box of cigarettes during the production process of cigarettes.

[0003] In cigarette production, due to the influence of packaging machines or other factors, during the process of folding the outer film and conveying it to the soldering iron mechanism for fixation, the outer film may become loose, wrinkled, have bubbles on the side seals, be loose, or unsealed, which in turn affects the sealing of the transparent film for cigarette packaging.

[0004] Good sealing can extend the storage time of cigarettes, reduce the impact of external temperature and humidity on cigarettes and the loss of water in cigarettes, and effectively prevent the leakage of cigarette fragrance and contamination of other flavors during long-term storage. Cigarette packaging with poor sealing will cause the cigarette fragrance to leak and odor to cross-flavor due to long storage time. Changes in the external environment will also cause the cigarettes to dry and mold, seriously affecting the quality of the cigarettes. Therefore, the sealing of the transparent paper for cigarette packaging is an important physical indicator of cigarettes in the production process.

[0005] To produce cigarette packages with good sealing performance, it is necessary to properly adjust the conveying mechanism, ironing mechanism and sealing mechanism of the cigarette packaging machine, so that the cigarettes can be stored for a longer time while ensuring their quality. Only when the sealing performance of the cigarette box is detected can the sealing mechanism of the cigarette packaging machine be properly adjusted, so it is very important to measure the sealing performance of the cigarette box.

[0026] When in use, the sample is placed in the conveyor belt 2, and the drum wheel 2 is driven to rotate by the first stepper motor, thereby driving the conveyor belt 2 and the sample 1 to move onto the sealing bottom plate 6.
