•革新改造氨纶包芯纱装置改造及电气控制方案张石峰(晋中经纬天盈机械有限公司技术中心,山西晋中０３０６００)摘要:为了提升氨纶包芯纱成纱质量,介绍氨纶包芯纱装置纺纱原理和技术要求,详细分析前罗拉驱动式和伺服控制系统驱动式氨纶包芯纱装置的改造方案及特点.指出:前罗拉驱动式改造方案的前罗拉和导丝辊间采用链条传动,结构简单可靠、维护方便、改造成本低,但更换工艺链轮费时费力,牵伸比为近似值,应用场合有限;采用伺服控制系统驱动式改造方案,可减轻前罗拉负荷,减少主机故障率,工艺参数由触摸屏输入,牵伸比变化方便且更为精确;目前的主流细纱机均可安装氨纶包芯纱装置,伺服控制系统驱动式更符合发展需求.关键词:氨纶;包芯纱;芯丝;工艺链轮;牵伸比;罗拉;导丝辊;伺服控制系统中图分类号:TS１０３．８１文献标志码:B文章编号:１００１Ｇ９６３４(２０２３)０４Ｇ００５８Ｇ０３SchemeofModificationandElectricalControlofSpandexCoreＧspunYarnDeviceZHANGShifeng(TechnologyCenter,JinzhongJingweiTianyingMachineryCo．,Ltd．,Jinzhong０３０６００,China)Abstract:InordertoimprovethespinningqualityofspandexcoreＧspunyarn,thespinningprinＧcipleandtechnicalrequirementsofspandexcoreＧspunyarndeviceareintroduced,andthetransＧformationschemeandcharacteristicsofspandexcoreＧspunyarndevicedrivenbyfrontrollerandservocontrolsystemareanalyzedindetail．Itispointedoutthatthefrontrollerdrivetransformationschemeadoptschaintransmissionbetweenthefrontrollerandthegodetroller,whichissimpleandreliableinstructure,convenientinmaintenanceandlowincost,butitistimeＧconsumingandlaborioustoreplacetheprocesssprocket,andthedraftratioisapproximateandtheapplicationislimited．TheservocontrolsystemdriventransformationschemecanreＧducetheloadofthefrontroller,reducethefailurerateofthehost,theprocessparametersareinputbythetouchscreen,andthedraftratiochangeisconvenientandmoreaccurate;atpresＧent,themainstreamspinningframecanbeinstalledwithspandexcoreＧspunyarndevice,andservocontrolsystemdrivenismoreinlinewiththedevelopmentneeds．KeyWords:spandex;coreＧspunyarn;corefilament;processsprocket;draftratio;roller;godetroller;servocontrolsystem收稿日期:２０２２Ｇ０４Ｇ２７;修回日期...
