多组分耦合式纺纱机理及控制系统开发

Mechanism and control of multi-component coupled spinning

根据质量守恒定律推导分析了多组分耦合式纺纱机理,并基于可编程控制器(PLC)和伺服电动机进行了控制系统软硬件开发。基于传统细纱机的系统和功能,利用新型的同轴、异速、多组分三后罗拉轴结构,以3种不同的速度喂入粗纱,可得到新式的多组分纱线。基于该结构,由输入参数导出细纱机各个参数之间的转换关系,以此为依据,根据多组分耦合式纺纱的工艺原理,控制多罗拉耦合牵伸,实现多组分耦合式纺纱过程。该系统集成了混配色和纺纱两个功能,使传统纺纱流程中的前后两道工序可在三组分细纱机上一次完成。实验表明,该系统能纺出符合要求的纱线。

The mechanism of multi-component coupled spinning is derived according to the law of conservation of mass, and thehardware of controlling system is designed and developed on the basic of PLC and servomotor. On the basis of analysis of system and functionof traditional spinning machine, a new multi-component yarn can be obtained by a novel coaxial, allometric, multi-component tri-rollerstructure with three different feeding speed. The conversion relationship between the spinning frame parameters is derived from the inputparameters based on the structure. According to the relationship between various parameters derived experiment,PLC is used to control ringspinning draft control system as the main body of hardware, and be able to achieve the multi-component coupled spinning process. The systemintegrates two function of mix of color and spinning, which can make the two procedures in traditional spinning process done in one spinningmachine. Experiments show that the system can meet the requirements of yarn.
