Abstract:

The nipper opening-closing time of a cotton comber closes affects the combing quality. In order to realize accuracy control of nipper motion of a cotton comber, determine the quantitative relations between process parameters and the nipper opening-closing time, a calculation model of the nipper opening-closing time was developed based on the analysis of the nipper driving mechanism of a cotton comber, the nipper mechanism and the nipper motion theory. The factors affecting the nipper opening-closing timing and closing time were obtained. Then, the quantitative relations between the detaching gauge and the nipper opening-closing time of a cotton comber was obtained by choosing the factor named detaching gauge. This study offers a reference for the nipper opening controlled technology of a cotton comber, and provides theoretical support for improving the combing quality in textile machines.

Key words: cotton comber, niper mechanism, opening-colsing time, detaching gauge
