摘要
[目的]研究不同框栏开口形状与尺寸、打辊转速、物料流量对打叶质量的影响与贡献率,探索提高叶片结构适用性的优化打叶参数组合。[方法]以河南烟叶为分析对象,采用正交试验设计,利用直观分析、方差分析、SSR检验、因素贡献度分析等分析方法对试验数据进行分析。[结果]在试验范围内,各因素对叶片结构影响的主次顺序为框栏、物料流量、转速,较优水平的打叶参数组合为一打六边形框栏组合、物料流量12000 kg/h和打辊转速35 Hz。[结论]利用正交设计试验方法进行打叶参数优化,可减少试验次数,快速实现“降大提中控碎去梗”的目的,为满足卷烟工业企业对打后叶片结构需求变化提供了技术支持。
[Objective]To learn about the influences and the contribution rates of different shapes of frame,intensities and material flow on threshing quality.To explore the optimum combination of threshing parameters for improving the applicability of strip structure.[Method]We designed orthogonal test to study the relationship between threshing quality and main process parameters in the process of threshing based with tobacco leaves in Henan Province.The data were analyzed by means of intuitive analysis,variance analysis,SSR test and factor contribution analysis.[Result]In the test range,the order of the influence of each factor on the strip structure was frame bar,material flow rate and rolling speed.And the optimal level of the combination of threshing parameters was a dozen hexagon frame combination,material flow 12000 kg/h and rolling speed 35 Hz.[Conclusion]The efficiency can be improved by using an orthogonal test design to optimize the threshing parameters,and achieve the test purpose of reducing large-sized strips,increasing medium-sized strips,controlling fragmentation and stem ratio,which provided technical support to meet the needs of cigarette industry enterprises for the change of strip structure.
