Method and device for controlling volume flow of tobacco material storage cabinet

The invention provides a tobacco material storage cabinet volume flow control method and device, and belongs to the technical field of tobacco processes. The method for controlling the volume flow rate of the tobacco material storage cabinet at least comprises the following steps that 1, sectional area information Si is obtained according to tobacco material surface contour information obtained through scanning; 2, tobacco material volume flow information of the storage cabinet is obtained; and 3, controlling the volume flow rate of the tobacco material discharged from the storage cabinet. The invention further discloses a tobacco material storage cabinet volume flow control method. The detection of the material surface information of the storage cabinet is combined with the regulation and control process of the discharge belt of the storage cabinet. The stability of the material volume flow during discharging of the storage cabinet is achieved, and the volatility of the discharging volume flow of the materia
