PASSIM80卷烟机刀头进刀机构的改造

Modification of Cut-off Knife Feed Mechanism in PASSIM80 Cigarette Maker

针对PASSIM80卷烟机刀头自动进刀机构存在进刀棘轮、棘爪磨损较快,更换频繁等问题,对该机构进行了改进。采用单向超越离合器取代棘轮、棘爪装置,通过调整气缸行程及设定进刀时间控制进刀量,改进后刀片的使用寿命由7～8h增加到30～40h,刀头机构维修周期由1～2月延长到1年,提高了设备的有效作业率。

The ratchet wheel and pawl of automatic knife feed mechanism in PASSIM80 cigarette maker had to be replaced frequently because of serious wear. The feed mechanism was modified as following： 1 ） the ratchet pair was replaced by an one-way overruning clutch; 2） knife feeding was controlled by adjusting cylinder stroke and setting feeding time. The working life of knife prolonged from 7-8 hours to 30-40 hours, the maintenance period of feed mechanism prolonged from 1-2 months to 1 year, and the machine efficiency was improved accordingly.
