为解决再造烟叶丝在掺配过程中物料欠松散、铺料不匀、掺配均匀性差等问题，进行了相关研究与改进：①改进松散装置布局，将松散装置安装于皮带秤后双向输送带的出料口处，使该装置达到最佳松散效果；②利用行星轴式的无中心轴技术设计鼠笼式松散辊，避免中心轴对再造烟叶丝铺料产生影响；③利用单一变量法，得到传统式松散装置的最佳转速为114 r/min，鼠笼式松散装置的最佳转速为48 r/min；④利用“九宫格”式分割技术设计了检测掺配物铺料均匀性方法，在相同实验条件下，分别利用传统式和鼠笼式松散装置对再造烟叶丝松散度、铺料连续性、掺配均匀性进行对比试验。结果表明：①建立的分割式检验掺配物铺料均匀性的检测方法，提升了再造烟叶丝铺料均匀性的检测水平，消除了再造烟叶丝实际瞬时流量与设定瞬时流量的偏差。②采用鼠笼式松散辊代替传统式松散辊，有效提高了再造烟叶丝的松散效率和掺配均匀性，再造烟叶丝与叶丝在单位区域内所占比例之差的波动区间由±5%减少到±0.5%。改进后较好地解决了再造烟叶丝在掺配过程中的松散度和均匀性问题，提升了烟丝内在品质的稳定性。

To promote the loosening, spreading and blending of cut reconstituted tobacco, following improvements were carried out: 1)Relocating the loosening device to the outlet of the two-way belt behind the belt weighter to obtain the optimal loosening effect. 2) Designing a cage type loosening roller by incorporating planetary shaft structure to avoid tobacco spreading from being interrupted by a central shaft. 3)The optimized rotation rates for traditional and cage type loosening devices obtained by single variable testing were 114 and 48 r/min, respectively. 4) Grid sampling method was used for evaluating the uniformity of tobacco spreading. Under the same experimental conditions, the traditional and cage type loosening devices were compared in terms of loosening degree, spreading continuity and blending uniformity of cut reconstituted tobacco. The results showed that: 1)The developed grid sampling method effectively improved the testing precision of spreading uniformity and eliminated the deviation between actual and set instantaneous flow of cut reconstituted tobacco. 2) Replacing traditional loosening roller with cage type device effectively improved the loosening efficiency and blending uniformity of cut reconstituted tobacco, the difference between the proportions of cut reconstituted tobacco and cut strips in a unit area decreased from ±5% to ±0.5%. The loosening degree and blending uniformity of cut reconstituted <br> tobacco and the consistency of intrinsic quality of cut filler were improved.
