本文根据高频器控制系统的结构及作用原理,采用特定的外部软件程序对系统内部软件程序予以调制,将变频器输出的正弦波变换成三角波或阶跃三角波,扩展了变频器的横动功能,实现了变频器在高速纺丝卷绕成形控制系统中的应用,控制精度高、效果良好。 1,化学纤维高速纺丝卷绕成形的工艺简介 化学纤维高速纺丝机的关键是卷绕成形。国内高速纺丝所用的卷绕机绝大部分是由原德国制造的SW_(4s)或SW_(46s)卷绕机,整机由两部分组成,第一部分是由导丝器、吸丝口、断丝器、监丝器组成的导丝系统;第二部分是由换
In this paper, according to the structure and function principle of the high-frequency control system, we use special external software program to modulate the internal software program, transform the sine wave output from the inverter into triangle wave or step triangle wave, , Has realized the frequency changer in the high speed spinning winding forming control system application, the control precision is high, the result is good. 1, high-speed chemical fiber spinning winding process Introduction Chemical fiber high-speed spinning machine is the key to winding forming. The spinning machine used in domestic high-speed spinning is mostly composed of SW_ (4s) or SW_ (46s) winders made in Germany. The whole machine is composed of two parts. The first part consists of yarn guide, Wire cutters, wire gauges composed of wire system; The second part is by change
