[0002] The tobacco shred flow formed by the feeding system of the cigarette machine is sucked along the suction channel, is adsorbed on the circulating suction belt to form a tobacco shred bundle, and after trimming by the uniformizer, the uniform tobacco shred bundle is sent to the cigarette gun to be combined with the cigarette paper to be rolled into a cigarette. The uniformizer is displaced up and down according to the change of the tobacco density in the cigarette, and the tobacco shred bundle is trimmed by the notch blade disc to make the cross section of the tobacco shred bundle uniform and consistent, and the weight of the tobacco shred bundle of a fixed length meets the process requirements. The tobacco shred trimmed by the uniformizer is sent to the feeding system by the back silk conveying device for repeated use. The cigarette back silk amount is one of the important parameters for the control of the cigarette machine, and affects the uniformity and stability of the tobacco feeding of the cigarette machine. During the suction forming process, the back silk amount is generally required to be 25%-40% of the feeding amount. If the back silk amount is insufficient, the empty head rate of the cigarette will increase, and the quality of the cigarette will be unstable.
