[0002] During the cigarette strip packaging process, the preheating and sealing of the cigarette strip transparent paper is one of the main steps of cigarette strip packaging. First, the long-side lapping needs to be sealed. Specifically, the cigarette strip transparent paper is wrapped around the cigarette strip, and its long sides are overlapped and heat-sealed; then, the cigarette strip transparent paper at both ends of the cigarette strip is sealed.

[0003] Among them, the sealing of the long-side lapping is the key to cigarette strip packaging. Most cigarette factories basically seal the long-side lapping manually. Manual operation cannot ensure that the long-side lapping is neatly heat-sealed. If the long-side lapping is not neatly heat-sealed, it will affect the packaging effect of the cigarette strip transparent paper at both ends of the cigarette strip, and further affect the packaging effect of the entire cigarette strip. In addition, the manual operation is difficult, and workers need to spend a lot of time practicing to master it. Moreover, there may be differences in the techniques of workers, which will make the packaging effects uneven and cannot achieve unified quality.
