摘　　要：为解决S400型残烟机回用烟丝中含杂物较多而导致烟丝纯净度不高等问题,对烟丝回用工艺及设备布局进行了优化和改进。在喂料机后增加一台三层振动筛分机,实现对初级杂物的分离并筛选出回用烟支;在两级轻重分离器后增加一套风选风送系统,实现对胶块等较重杂物的分离和剔除;在自动装箱系统前增加两台串联的烟丝精选机,实现对回用烟丝中纸片和纤维等杂物的剔除。以宁波卷烟厂生产“利群”牌卷烟所产生的残烟支为对象进行测试,结果表明:(1)残烟机改进后回用烟丝中未发现大纸片和其他杂物,小纸片含量由18.40片/500 g减少至0.18片/500 g,降低99.02%;(2)工艺优化后回用烟丝的整丝率、含水率等工艺指标与改进前基本一致,烟丝品质未受到影响。该技术可为进一步完善回用烟丝生产工艺提供支持。To minimize the amount of foreign matters in tobacco reclaimed by S400 tobacco reclaimer,the reclaiming process was optimized.A three-layer vibration screen was added behind the feeder to separate recoverable cigarettes from foreign matters.A pneumatic separating and conveying system was added behind the two-stage gravity separator to separate and reject the heavier matters including dried glue pieces.Two sorters were added serially in front of the automatic case filling system to reject paper flakes and fibers from reclaimed tobacco.The modified tobacco reclaimer was tested with the rejected cigarettes of brand“Liqun”in Ningbo Cigarette Factory.The results indicated that:1)No large paper pieces and other foreign matters were found in the reclaimed tobacco,and the content of small paper pieces in cut tobacco of 500 grams reduced from 18.40 pieces to 0.18 pieces,i.e.decreased by 99.02%.2)The proportion of integral tobacco strand and moisture content of reclaimed tobacco were basically unchanged,and the quality of reclaimed tobacco was not affected.This technology provides a support for further improving tobacco reclaiming technology.
