摘要
探讨SX3-6840VT型板式上销的技术特点及其对成纱质量的影响。从牵伸理论出发,分析了细纱机6833型传统上销存在的不足之处,并进行了上销结构改进,通过进一步加长上销宽度,加装整体弹簧板片,使新上销的性能得到进一步改进,有利于在牵伸浮游区更好地控制纤维运动并消除胶圈滑溜与运行不稳定现象,使成纱质量得到进一步改善。认为:SX3-6840VT型上销具有结构简单、使用方便、成本低等特点,使用该上销纺纱能够有效提高成纱质量水平。
Technology property of SX3-6840VT plate top pin and its effect on finish yarn quality were discussed. From aspect of draft theory, disadvantage of traditional spinning 6833 top pin was analyzed then the top pin structure was modified. Through increasing top pin width and installing whole spring plate, property of new top pin was modified fur- ther, fiber in draft floating zone could be controlled well, phenomenon of apron slipper ＆ unstable could be avoided, final- ly finish yarn quality could be improved further. It is considered that structure of SX3-6840VT plate top pin is simple and convenient,the cost is lower and finish yarn quality could be improved by using SX3-6840VT plate top pin.
