Application of Conjugate Cam Mechanism in Second Cigarette Pusher in YB47 Hard Packer

As a solution to oil leak at the second cigarette pusher caused by wide clearance between pusher shaft and sleeve and oil temperature rise, two sets of conjugate cams were adopted to control the horizontal and vertical movement of the second pusher in YB47 hard packer respectively, and the pusher accomplished the movement by means of rolling instead of sliding in its sleeve. Comparing with YB25 packer wherein the pusher is driven by gears, there is no oil leak in the second cigarette pusher in YB47 packer, the number of rejected defective packets reduces from>10 to 0 and machine shutdown reduces from 1-2 to 0 per shift. Both machine efficiency and packet packing quality are improved.
