现代棉纺细纱机后区牵伸变换原理的研讨

Study on Drawing Change Principle of Back Area for Modern Cotton Spinning Machines

围绕棉纺细纱机的后牵伸区 ,对牵伸变换的要求、位置、特征、配置和改造五个方面进行分析探讨 ,指出在第二、第三两种牵伸传动路线上 ,只有将后区牵伸变换齿轮选择在独立的后区牵伸传动路线上 ,才能实现改变后区牵伸而不影响总牵伸 ,方便调整工艺。最后介绍了A5

Some discussions are made to the requirement of drawing change,location,features,configuration and modification thereof regarding the back area of drawing for spinning machines.The paper points out that only are the switching gears of back drawing area located separatedly on the back drawing driving system can comes true the fact that the general drawing system work separately from the change of the back drawing systems,regarding the second and the third drawing driving systems and more, it is easy for adjustment of process.The paper concludes itself with the introduction of modification practice of drawing switching gears of back area on spinning machines A513W.
