Improvement of Cigarette Separating & Conveying Device in PROTOS 70

The cam mechanism of the tobacco rods separating drum in PROTOS 70 filter cigarette making machine was hard to be lubricated and inclined to draw in tobacco dust because of connecting with negative pressure, it usually worked in a dusty environment and short of lubrication, which resulted in serious wear of roller follower and cam and badly affected machine operation efficiency. Therefore, the separating device was improved wherein the separating piece assembly was pushed forward directly by the follower assembly of the cam mechanism and pushed backward by a spring. The cam mechanism was completely sealed in a guard and isolated from positive and negative pressure air and dust. The guard was filled with lubricating oil which ensured good lubrication of the cam and roller.
