摘　　要：为解决制丝生产线光电除杂过程中因物料摊铺过厚而导致光电除杂效率降低等问题,设计了一种片烟均匀布料装置。该装置安装在转辊式分拣机上方,由驱动机构、可调支架、转轴以及布料锥盘等组成;通过对布料锥盘上的片烟进行受力分析并开展布料试验,确定锥盘锥角为29°,转速为79.0 r/min;转轴最小直径为30 mm,通过2个角接触轴承固定在可调支架上,采用型面连接的方式带动锥盘转动。以济南卷烟厂生产的“泰山(白将军)”牌卷烟配方片烟为对象进行测试,结果表明:应用均料装置后,分拣机输送底带上物料分布宽度增加650 mm,厚度降低55 mm;光电除杂器异物剔除率由86.67%提升至95.56%,误剔率由0.23%降低至0.15%。该技术可为提高除杂设备剔除性能提供支持。To improve the efficiency of photoelectric foreign matter removal in tobacco primary processing,a tobacco strip spreader was designed and installed above the rotary roller sorter.The spreader mainly consists of a drive mechanism,an adjustable bracket,a rotating shaft,and a conical disk.Based on the force analysis of tobacco strips on the conical disk and strip spreading experiments,the cone angle of the conical disk was determined to be 29°and the rotation speed to be 79.0 r/min.The minimum diameter of the rotating shaft was 30 mm.The rotating shaft was situated on the adjustable bracket with two angular contact bearings,it drove the conical disk by profile connection.The spreader was tested on the blended strips of cigarette brand“Taishan(White General)”in Jinan Cigarette Factory.The results showed that the spreading width of the strips on the bottom conveying belt of the sorter increased by 650 mm,and the thickness decreased by 55 mm;the foreign matter rejecting rate increased from 86.67%to 95.56%,and the error rate decreased from 0.23%to 0.15%.This technology provides support for improving the performance of foreign matter removal equipment.
