In order to reduce the failure rate and equipment cleaning time,an automatic cleaning device for SE tobacco rod conveying channel in ZJ112 cigarette maker was designed,wherein a pneumatic cylinder pushed a cutting knife to cut off the tobacco rod quickly,and compressed air was introduced into the front section of the microwave source and the U-shaped guide respectively to blown any residues off the microwave source channel when the machine was stopped. Based on the master PLC of ZJ112,the control system adopted backup input/output address and controlled cleaning process through programming. Test running was carried out on cigarette brand"Mount Tai(Red General)"in Jinan Cigarette Factory,the results showed that the quality of cigarettes was not affected by the installation of the said automatic cleaning device. The effective cleaning rate reached 98.61% after machine shutdown,and cleaning duration reduced by 10.4 s. The cleaning device decreases operators'labor intensity and promotes machine efficiency.%为降低ZJ112卷接机组的故障停机率,减少设备清洁时间,设计了一种SE烟条输送通道自动清洁装置.该装置通过推杆气缸带动切刀动作快速切断烟条,分别在微波源前部和U型导管处增加两路压缩空气,在设备停机时将切断的烟条从微波源通道内吹出,实现烟条输送通道的自动清理.控制系统以原有设备主PLC为核心,采用备用输入/输出地址,通过编程自动控制清洁流程.以济南卷烟厂生产的"泰山(红将军)"牌卷烟为对象进行测试,结果表明:自动清洁装置安装后对烟支质量无影响,设备停机后有效清洁率达98.61%,节省清洁时间10.4 s/次.改进后机组降低了操作工的劳动强度,提高了设备运行效率.
