[0002] The function of the feeding system in the tobacco factory workshop is to provide stable and continuous tobacco for the suction ribbon in the wind chamber. In the whole feeding system, the tobacco is limited twice, impurities are removed by magnets, and stems are removed by wind separation twice, so that the quality of the tobacco is better and the feed amount to the wind chamber is more accurate.

[0003] According to the working condition of the feeding system, it is generally divided into three parts: metering blanking, quantitative tobacco supply and wind separation and stem removal. Among them, the metering blanking part mainly includes a blanking device and a metering tube, and its working principle is: the tobacco is allowed to enter the blanking device through air delivery, and then the tobacco enters the metering tube through the bottom of the blanking device. However, when the tobacco enters the blanking device through the air delivery pipe, due to the effect of inertia, the tobacco will directly hit the inner wall of one side of the blanking device, which will easily cause the tobacco to be squeezed, thereby causing a greater impact on the looseness of the tobacco, resulting in poor quality stability of the produced cigarettes. Therefore, how to make the tobacco less likely to be squeezed and reduce the impact on the looseness of the tobacco has become a technical problem that technicians in this field urgently need to solve.
