天津工业大学毕业设计（论文）题目：细纱机落纱小车卸管装置姓名邱杰学院机械工程学院专业机械工程及自动化指导教师赵永立职称讲师2012年6月5日摘要纺织业是我国竞争力较强和国际依存度较高的产业，也是劳动密集和具有比较优势的传统产业，一直是我国国民经济的支柱和出口创汇的重要产业。落纱卸管装置，属于细纱机落纱技术领域。该装置包括直线运动单元、支架电机、带轮机构、顶杆、液压缸、升降机构和平移机构。大部分细纱机的纱管与锭杆之间采用锥而贴合实现自锁，锭杆的外锥而与纱管的内锥而贴合得较为紧密，以保证细纱机纺纱时纱管商速运转平稳，噪声小，功率消耗小.其靠落纱尤其是将纱管与锭杆停靠分离（卸载）非常重要。液压卸纱装置是计对现有技术的不足之处,提供一种液压握紧卸管装置.它以小碰纱线将纱管与锭杆分离开来完成卸载作过程.同时具有自动化程度高装置简中.靠等优点适合用于移动式自动落纱机使用。关键词：纺织业；落纱机；自动化；移动式自动落纱机AbstractTextileindustryisstrongcompetitivenessandhighdegreeofdependenceoninternationalindustryinChina,islabour-intensiveandtraditionalindustrieswithacomparativeadvantage,areimportantpillarsofthenationaleconomyandexportindustriesinChina.Doffingmachinedouble-bar-dialflushdischargetubedevices,belongingtothedoffingspinningmachinetechnology.Thedevicesincludelinearcampaignunit,thesupport,thefirstmotor,firstdrive,thetopblock,thesecondmotor,transmissionandimpactII;thesecondtransmissionmechanismincludingthedial,dial,thefirstlink,thesecondcon-rodandspring.Mostofthebobbinspindlespinningrodbetweentheconeandsticktoimplementitsownlock,outsideofingotRodconebobbinConeandstickmoreclosely,toensurethatwhenspinningframespinningbobbinspeedstableoperationandlownoise,smallpowerconsumption.BydoffingespeciallyseparatingthebobbinspindleRod-Cho(finishingunloading)isveryimportant.Thisinventionisthesmallfootofmetersonexistingtechnologies,provideadoffingmachinedouble-bar-dialflushdischargefinishingdevice.Itbyasmalltouchyarnbobbinsandseparatedfromthespindlepoletocompletetheuninstallprocess.AtthesametimeJanehasahighdegreeofautomationdevices.Theadvantagesofautomaticdoffingmachineissuitableformobileuse.Keywords:Textileindustry;Doffer;Automation;Mobileautomaticdoffer目录第一章概述..............................................11.1纺织工业发展概况..............................................11.2国内三家公司细纱机短车集体落纱装置............................11.3国外自动落纱粗纱机特点........................................2第二章细纱落纱方式.......................................42.1自动落纱技术分类...............................................42.1.1青泽型超长细纱机简介......................................42.1.2国外细纱机倾角集体落纱机系统..............................42.1.3迈耶自动落纱机............................................52.2独具特色的圆盘式落纱机.........................................62.3细纱机自动落纱需要的功能.......................................82.3.1脱开锭子与铜管的联合.......................................92.4双圆盘落纱小车实现自动化.......................................9第三章方案对比与选择....................................113.1落纱方案.....................................................113.2意大利马佐里FT1-D............................................123.3日本丰田FRD..................................................133.4国内自动落纱粗纱机特点.......................................133.4.1天津宏大的JWF1418A.........................................133.4.2河北太行THFA4461.......................
