棉精梳机分离罗拉运动位移研究

Research on Motion Displacement of Detached Roller of the Cotton Comber

为弥补对棉精梳机精梳分离运动位移研究的不足,分析棉精梳机分离罗拉与锡林、钳板等机构的位置关系,设置棉精梳机工艺参数,根据棉精梳机对分离罗拉运动的要求计算出关键点的分度值及对应的位移量,得到分离罗拉运动位移图和关键点分度值及对应位移量的计算模型。指出:分离罗拉在不同分度的运动位移量影响正常开车及精梳条质量,当锡林轴及钳板运动确定后,分离罗拉位移曲线可由须丛搭接搭合率η、分离牵伸倍数E、给棉罗拉给棉量A、有效输出长度Sy,通过须丛纤维长度l等参数决定。

To offset the inadequate research on the motion displacement of the detached roller of the cotton comber, analysis is done to the location relationship between the detached roller, the cylinder, and the nipper mechanism and the comber parameters are set.Considering the requirement of the comber on motion of the detached roller, the calculation model for the scale interval in some critical points relevent to the motion displacement is found. It is pointed out that the motion displacement in different scale interval of the detached roller is in close relation to the normal start-up and the quality of the combed sliver.Once the motions of the cylinder shaft and nipper are fixed, the curve of the motion displacement of the detached roller is controlled by the following.percent pass of the fiber cluster lapping rate η,the draft mutiply of the detached roller E ,cotton feeding quantity A ,effective length Sy of the output fiber,and length of the passed cluster l.
