浅析细纱机牵伸部件的技术创新

Our Tentative View on the Tech-innovation of the Drafting Parts on the Spinning Frame

为了分析细纱机牵伸装置用部件的技术发展动态及其前景趋势,对四胶圈牵伸装置,前后区压力棒牵伸,胶圈上、下销改进,胶圈使用,前胶辊前移量的改变等细纱机牵伸部件创新的机理及应用进行了论述,指出纺纱牵伸部件虽小,作用巨大,对提高纱线质量、加大牵伸影响深远。说明后区牵伸压力棒、胶圈上销、下销改造等技术已经成熟,可以推广,其它新型牵伸部件的创新应用必须充分了解其作用机理,并与工艺优选相结合,才能取得好的效果。

Aiming at the analysis of the developing trend and the future of the drafting device on the spinning frame,description is done to the quadruple-apron drafting device,the drafting with press bar in front and rear section,modification of the bottom and top apron pin,application of the apron and the mechanism and the movement of the fore apron.Conclusion is made that the drafting part is small,but it is important in spinning for good quality of resultant yarn with profound significance in drafting process.It proves that the processes such as draft press bar in the rear section,the both top and bottom apron pin come to maturity,worthy of being promoted.rech-innovation and application of other new drafting parts should start with the mechanism integrated with the process optimization for better result.
