Effects of Cigarette Making Machine Setting on Cut Tobacco Distribution in Cigarette

In order to narrow the fluctuation of individual weight and draw resistance of cigarette and improve the uniformity of cut tobacco distribution in cigarette, the main parameters of rod forming system in PASSIM7000 cigarette maker were optimized with orthogonal test method, and the effects of pocket number and depth of ecreteur disc on quality of cigarette making were studied. The results showed that: 1) the optimal parameters were: rotational speed of projector roller, picker roller and carded drum 1250, 180 and 18 r/min, respectively; air pressure in suction chamber 11200 Pa; number of warp of suction band 25; 2) specifications of ecreteur disc were: pocket number 6, pocket depth 3.8/1.5 mm; 3) within the test range, comparing with the control, the standard deviations of individual cigarette weight reduced by 3.42 mg and tobacco density in tobacco rod decreased by 6.82 mg/cm³.
