Background As is known, during the production of cigarettes, when pushing a group of cigarettes into a pack, there are mainly two ways, the first being pushing the filter end and the second pushing the tobacco end. Along with the increase of cigarette packaging forms, higher requirements are also put forward on cigarette packaging equipment, if the packaging forms require that the packaging equipment is pushed in a tobacco shred end pushing mode, at higher speed, the tobacco shred end of a cigarette is easy to damage under the action of external force, and particularly, when pushing a cigarette group without aluminum foil lining paper, the stress requirement on the cigarette group is higher. The existing cigarette packaging equipment is divided into two packaging processes of single-path packaging and double-path packaging, the movement of the die boxes is generally driven by a packaging conveyor belt or a packaging wheel, the distance between the die boxes and the number of stations are fixed values, and in the packaging process, the pushing frequency of cigarette groups of the die boxes is consistent with the output frequency of cigarette packages, namely single-in single-out or double-in double-out. When the cigarette production is carried out by pushing the cut tobacco ends, the pushing speed of the cigarette group is higher, the cigarette group is more easily deformed and damaged due to stress, so that the packaging quality is influenced, and the output speed of the cigarette packet is lower due to the fact that the pushing speed of the cigarette group is lower, so that the packaging efficiency of the cigarettes is influenced. Therefore, how to ensure the packaging efficiency and the packaging quality of cigarettes at the same time is a technical problem to be solved by the technicians in the field.
