摘　　要：针对HC500型精梳机,利用分离接合过程中分离罗拉速度曲线及钳板速度曲线的变化特征,分析分离丛的不同截面纤维质量分布情况及其对棉网均匀度的影响。当精梳机给棉工艺、分离隔距等工艺参数不变时,利用2 mm切断称重法测试得到分离罗拉顺转定时不同时分离丛的质量分布曲线,根据精梳机分离接合规律对不同的纤维丛进行接合,求得精梳机输出棉网的2 mm片段质量CV值。结果表明:分离丛质量分布曲线形态,决定了棉丛的搭接质量及精梳机输出棉网的均匀度;当纤维长度为29 mm、落棉隔距为9.5 mm、给棉长度为5.2 mm、HC500型精梳机分离罗拉的顺转定时为15.5分度时,棉网2 mm片段的质量CV值最小。On the HCS00 comber, weight distribution of fiber in different sections and its effect on the evenness of cotton web are analyzed according to the changing characteristics of speed curve of detaching roller and nipper in the process of separation and joint. If the process parameters of feeding and separation gauge are constant, weight distribution curve of fiber bundle at different clockwise rotations are achieved by the method of 2 mm cutting-weighing and the 2 mm weight CV of cotton-web at different forward motion timings are calculated according to the regularity of separation and joint. The results show that the joint quality of fiber bundle and the evenness of outputting cotton-web are decided for the form of weight distribution curve of fiber bundle, 2 mm weight CV of cotton web is the lowest when forward motion timing is 15.5 index, fiber length is 29 mm, noil gauge is 9.5 mm and feeding length is 5.2 mm.
