摘要
Abstract
When the bag filters in the centralized air dusting system for cigarette makers are being cleaned,the negative pressure in the cigarette maker will be decreased by 400-700 Pa sharply. Therefore, the air-jet device for cleaning the bags was improved. The optimal pressure and duration for air-jet device operation determined by orthogonal experiment were 0.5 MPa and 100 ms, respectively. Instead of switching on two sets of pulse electromagnetic valves simultaneously, only one set was switched on at one time. A PLC-controlled air compensation device was designed to offset the effects of air-jet cleaning. The results of application showed that: after improving, the impact caused by bag cleaning on negative pressure was reduced to 100 Pa, the fluctuation of negative pressure in cigarette maker was controlled within ±100 Pa, the cigarette weight was better controlled. The average tobacco loss from cigarette end decreased from 3.67 to 3.42 mg/cig.,and the rate of loose end cigarette reduced from 1.06% to 0.98%.关键词
