Abstract: In order to even cut tobacco distribution and avoid jam at tobacco inlet, the Solidworks Flow Simulation software was used to perform the CFD simulation analysis on the tobacco spreading effect of the equalizing plate in the flexible tobacco feeder. In combination with the simulation data of tobacco flow field, two modification methods were proposed. Type A featured four straight ribs and Type B featured two S-shaped ribs, and the length of the ribs was shortened to 250 mm, the radius of the plate. Type A, Type B and original plates were comparatively tested on the flexible tobacco feeders and CFD simulation analysis was carried out as well. The results showed that in the case of Type B plate, the suction air velocity in the entire flow field was higher than 10 m/s, the gradient of air velocity varied obviously, and the tobacco was conveyed fluently. This technology provides a technical support for promoting the feeding capacity of tobacco feeder.
