The design and manufacturing difficulty of the cigarette machine is reduced, because the wheel type suction forming machine has only one key operating component, the cigarette equipment suction forming wheel, the equipment structure is simpler, and the complexity and the number of operating components of the equipment can be greatly reduced, thereby reducing the design and manufacturing difficulty of the cigarette machine. The quality stability of the cigarette is further improved, the suction groove 320 and the suction screen of the wheel type suction forming machine move synchronously with the wheel, and there is no friction resistance in the tobacco conveying process, which solves the problem of the movement friction of the net belt suction forming tobacco bundle and can further improve the prediction of the cigarette weight control level and the vehicle speed. Maintenance is easier, the relative movement between the tobacco and the wheel body during the suction process of the cigarette equipment suction forming wheel causes almost no friction, which solves the quality problem caused by the friction between the tobacco and the equipment of the traditional cigarette machine. The wear-resistant metal screen is used for the suction screen, which greatly reduces the replacement and maintenance frequency.
