Objective: To solve the problems of low whole rate of the tobacco shredded from the cabinet, high rate of broken shreds and high concentration of regional dust. Methods: A flexible feeding and discharging system of the wire storage cabinet was designed, which effectively reduced the shredded tobacco and the regional dust concentration through the automatic telescopic sliding plate and the sliding and lifting raking roller. Results: After adopting the flexible feeding and discharging system of the wire storage cabinet, the change rate of the whole wire rate increased by 1.1%, from 80.2% to 81.1%, and the broken wire rate decreased to 2.2%; The regional dust concentration C-TWA decreased to 0.5 mg/m³. Conclusion: The improved wire storage cabinet achieves the purpose of cleaner production, cost reduction and efficiency enhancement.
