【摘要】 长绒棉与陆地棉相比，具有纤维长、强度高等优点，是纺高档纱的必备原料。随着纺织品结构的变化，以及人们消费水平的不断提高，国内外市场对长绒棉需求量不断增加。 但是由于长纤维在加工的过程中容易断裂和缠绕设备，所以长绒棉加工对加工设备要求非常高。我国的现有设备不能满足加工的要求，急需一种高效的加工设备。滚刀式皮辊轧花机就是这样一种设备。但是由于我国对于皮辊轧花机的研究历史比较短，与国外，尤其美国有一定的差距。 本课题作为国家计委课题的后续课题，在“九五”期间研制的高效皮辊轧花机6MPY—100B的基础上，通过试验，找出各个结构参数和运动参数之间的数学方程，然后利用参数优化的方法来求得各个结构参数和运动参数的最佳值和最佳匹配关系，为皮辊轧花机的研制提供理论设计基础。更多还原

【Abstract】 Compared with uplands cotton, long-staple cotton has the longer fiber and high tenacity. So it becomes the required component in weaving the high quality yarn. With the economic condition has become better, the structure of weaving has changed, and more and more long-staple cotton has been required. However long fiber makes the weaving process difficult, for the longer the fiber is, the easier it becomes to be ruptured and the easier the cotton gin be twisted.In foreign countries, especially in the United States, there is a long history in studying the long-staple cotton manufacturing machine-roller gin. But in our country, the study just began in 1970’s, and there had no breakthrough in these years. It is necessary to design a new kink of cotton gin to meet the demand of weaving industry.This thesis paper started from the experiments of long-staple cotton roller gins, with the model number 6MPY-100B, which was devised in the Ninth Five-year Plan. Then the equation of the parameters, including the dimension of leather roller, the rotate speed of leather roller, moisture percentage , etc, was discovered. And through making a search of the optimized relationship between every parameters, the maximum productivity was found.From the view of practice, the equation and the optimized relationship would be very helpful to the designing of roller gin.更多还原
