摘　　要：为了满足新版《卷烟工艺规范》对片烟结构的要求,采用混合正交试验和二次规划求解的方法,对菱形、六边形、圆形和蝶形框栏不同尺寸、不同打辊转速的打叶效果进行分析研究。结果表明:①采用六边形框栏进行打叶,将会有效降低大片率、提升中片率、降低叶中含梗率。②在9000 kg/h打叶复烤生产线中,一打采用3套2.75英寸(H0=69.9 mm)菱形框栏,辅以1套3.5英寸(A=88.9 mm)六边形框栏,打辊转速控制在560~660 r/min,可以满足打后大片率<45%、大中片率≥80%、叶中含梗率<1.5%的要求。In order to meet the structural requirements for threshed tobacco strips set by the new edition of Technical Specification for Cigarette,mixed orthogonal tests and sequential quadratic programming were used to study the effects of threshing with rhombic,hexagonal,circular and papiliform openings of different sizes at different rotational speeds of a threshing drum.The results showed that:1)Adopting the frame basket with hexagonal openings could effectively reduce the percentage of strips with>25.4 mm,increase the percentage of strips of 12.7-25.4 mm,and reduce the stem content.2)When 9000 kg/h threshing and redrying line adopted three sets of frame baskets with 2.75-inch(H0=69.9 mm)rhombic openings and one set of frame baskets with 3.5-inch(A=88.9 mm)hexagonal openings in the first stage threshing and the rotational speed of threshing drum was controlled at 560-660 r/min,the threshed strips could meet the requirements for the large-sized strip percentage<45%,the large and medium-sized strip percentage≥80%and the stem content<1.5%.
