Abstract: During the cleaning process of YF17, YF17A cigarette storage and conveying device, a large amount of smoke enters the storage cylinder from the gap of the device. Due to limitation of the mechanical structure, the storage cylinder needs to be disassembled for effective cleaning. The long-term existence of cigarette dust will breed tobacco worms, which will seriously affect the quality of cigarettes. In view of this problem, a scheme for improving the smoke dust removal system of storage canisters is proposed in this paper. By analyzing the transmission structure of storage canisters of YF17, YF17A cigarette storage and conveying device, a system for removing smoke dust from storage canisters is designed to prevent smoke dust from entering the inside of storage canisters. At the same time, the smoke powder entering the storage tank is automatically cleaned out of the storage tank. After 300 days of verification in the storage tank of YF17, YF17A cigarette storage and conveying device, the function of the storage tank is achieved, which can effectively prevent the accumulation of smoke powder and breed smoke insects, and improve the quality of cigarettes. This improvement method has important reference significance for improvement of the storage tank structure.
