Abstract:

In order to reduce the irregularity of combed cotton sliver, a quantitative distribution model of fleece output by detaching roller was studied, a mathematical model for the aggregation of combed fleece at the flared mouth and the CV value of the evenness of converged sliver was established, and the universal applicability of the model was proved. A Matlab program was developed for the model and applied to a certain model of combing machine. The calculation results show that the position of flared mouth has a great influence on the evenness of the sliver it converges. The farther the flared mouth is away from the output roller, the worse the evenness of the sliver. When the coordinates of the center of flared mouth are (15, 0), the evenness of the sliver CV reached a minimum of 0.341%. This research method can be applied to the convergence of fleece and sliver, for example, the convergence of fleece of combing machine.

Key words: combing machine, position of flared mouth, converging sliver, evenness CV

摘要：

为了减小棉纺精梳棉条的不匀率,分析了分离罗拉输出棉网的定量分布模型,建立了精梳棉网喇叭口集聚及集聚棉条条干CV值的数学模型,并证明了模型的普遍适用性。将模型编制Matlab程序并应用于某种精梳机型,计算结果表明:喇叭口的位置对其集聚棉条的均匀度有较大影响,喇叭口距输出罗拉越远,棉条的均匀度越差,喇叭口中心坐标为(15,0)时,棉条的条干CV取得极小值0.341%。这种研究方法可应用于棉网、棉条集聚的场合,如梳棉机棉网的集聚。
