摘　　要：为解决当前打叶复烤中片烟结构不合理等问题,采用不同开口尺寸以及对菱边进行开齿、喷涂硬质合金处理等方法对不同规格框栏进行对比分析,并对常规框栏进行优化改进和测试.结果表明:①框栏开口尺寸与撕叶率、中片率、小片率、碎片率和含末率呈负相关关系,与大片率、大中片率呈正相关关系;②减少框栏开口尺寸以及进行菱边处理均能提高一级打叶机撕叶率,但会产生较大造碎;③与常规框栏相比,改进后复合开口框栏的撕叶率、中片率分别提高5.54和5.56百分点,大片率降低5.74百分点,含末率控制在≤0.8%范围内.该方法可为提高打叶效率、满足片烟结构控制要求提供支持.In order to obtain more strips of desirable sizes in green leaf threshing,the baskets with different opening sizes,shapes and opening edge treatments were compared,and conventional baskets were optimized and tested.The results showed that:1)The opening size of basket negatively correlated to lamina yield,the percentages of medium-sized and small-sized strips,the fine and dust contents in strips;while it positively correlated to the percentages of large-sized strips and large-to-medium-sized strips.2)Reducing the opening size or toothed and carbide casted opening edge might promote the lamina yield of the first stage thresher,but increase tobacco breakage.3)Comparing with conventional basket,the lamina yield and the percentage of medium-sized strips of the basket with mixed opening sizes increased by 5.54 and 5.56 percentage points respectively,the percentage of large-sized strips decreased by 5.74 percentage points,and the dust content was controlled under 0.8%.This method provides a support for improving threshing efficiency and meeting the requirements of strip structure control.
