Improvement of Spacer Plates in Cigarette Hopper of FOCKE 700S Hard Packer

To solve the problems of cigarette jam and staggering falling movement in discharge channel of cigarette hopper in FOCKE 700S hard packer, the spacer plates and discharge guide plates in the discharge channel was modified via analyzing the factors, which affect the movement, such as cigarette distribution, hopper shape and friction force acting on the cigarettes. The contact area between cigarettes and those plates was minimized, and the friction between cigarette and the spacer plates reduced accordingly. A tobacco discharge slot was added to discharge scattered tobacco out of discharge channel timely and ensure a free cigarette falling. After improvement, the rate of machine failure caused by cigarette jam in hopper reduced from 50%-60% to 25%-35%, and the machine efficiency was effectively improved.
