编号无锡太湖学院毕业设计(论文)题目机械式拧瓶机的设计及工程分析信机系机械工程及自动化专业学号学生姓名指导教师(职称副教授)(职称)2013年5月25日无锡太湖学院本科毕业设计(论文)诚信承诺书本人郑重声明所呈交的毕业设计(论文)机械式拧瓶机的设计及工程分析是本人在导师的指导下独立进行研究所取得的成果,其内容除了在毕业设计(论文)中特别加以标注引用,表示致谢的内容外,本毕业设计(论文)不包含任何其他个人、集体已发表或撰写的成果作品。班级机械93学号0923116作者姓名2013年5月25日II摘要拧瓶机是自动拧瓶生产线的主要设备之一,它是封口机的一种,广泛用于玻璃瓶或PET瓶的螺纹盖封口。由于螺纹盖具有封口快捷、开启方便及开启后瓶又可重新旋上瓶盖等优点,所以一些不含气的液料,诸如饮料、酒类、调味料等类似瓶包装的封口中大量采用螺纹盖封口。为了适应现代包装机高速、高效和高可靠性生产的需要,在广泛吸收国内外先进机型的基础上,本课题设计了全自动拧瓶机。它靠异步电动机带动传送带实现瓶子的输入和输出,中间在传送带上部巧妙地安置了转盘,给旋盖工作带来很大的便利,也大大提高了效率,旋盖装置更是此次设计的关键部件,靠电机带动空心轴以及其以上的机构旋转,同时上部的圆柱凸轮实现旋盖头的升降,旋盖头运用机械式的方法,夹头的另一头联接弹簧,运用杠杆原理实现瓶盖的夹紧。当旋盖头夹紧瓶盖时,上方的电动机启动开始旋盖。本课题的设计不但结构简单明了操作方便,而且实现了从进瓶到出瓶的全部自动化,具有速度可调、定位准确、旋盖可靠、运行平稳、无噪音和不伤瓶盖等优点,克服了传统机构的缺点,总体上达到了我们预期设计的目标。关键词拧瓶机旋盖头机械式杠杆IIIAbstractCappingmachineisoneofthemainequipmentoftheautomaticfillingproductionline,whichisakindofsealingmachine,andwidelyusedinglassorPETbottlessealedwithscrewcap.Screwcapwithsealingthefast,iseasytoopenandcanbereopenedafterthebottlescrewcaponthebottle,etc.sosomenongasliquidmaterial,suchasbeverages,wine,seasoningsandthelikeinalargenumberofthesealedbottleswithscrewcoverseal.Inordertoadapttotheproductionneedsofthemodernhighspeedpackagingmachine,highefficiencyandhighreliability,extensivelyabsorbingonthebasisoftheadvancedmodels,theprojectdesignstheautomaticscrewingmachine.Itisbeltdrivenbyinductionmotorstoachieveinputandoutputofthebottle,theuppermiddleoftheconveyorbeltturntablecleverlyplaced,thecaphascausedgreatconvenience,butalsogreatlyimproveefficiency,cappingdeviceisthekeytothedesignparts,relyonmotordrivenhollowshaftandtheinstitutionsrotation,whiletheupperpartofthecylindricalcamliftingofcappinghead.themethodofthecappingheadsismechanical.Theotherendofthechuckcouplingspring.Itusestheleverprincipleimplementationclampingbottlecaps.Whenthethecappingheadclampingcap,thetopofthemotorstartstartcapping.Notonlythestructureissimple,easytooperate,butalsothedesignandimplementationoftheprojectfromthebottleintothebottletothefullautomation,withadjustablespeed,accuratepositioning,cappingreliable,smoothrunning,nonoiseandnottohurtthecaps,etc,toovercometheshortcomingsoftraditionalinstitutions,theoveralldesigntoachievethegoalofourexpectations.KeywordsCappingMachineCappingheadMechanicalleverageV目录摘要............................................................................................................................................IIAbstract.........................................................................................................................................III目录............................................................................................................................................V1.绪论..............................................................................................................................................11.1本课题的设计背景...............................................................................................................11.2国内外发展...........................................................................................................................11.3本课题应达到的要求...........................................................................................................32.拧瓶机的整体设计....................................................................................................................42.1设计任务分析.......................................................................................................................42.1.1设计参数.........................................................................................................................42.1.2工艺路线.........................................................................................................................42.1.3技术要求.........................................................................................................................42.2拧瓶机的工作原理...............................................................................................................42.3总体方案确定.......................................................................................................................42.3.1方案一的介绍................................................................................................................42.3.2方案二的介绍................................................................................................................52.3.3方案三的介绍................................................................................................................52.3.4方案四的介绍................................................................................................................62.4方案比较..............................................................................................................................62.5采用方案的详细设计..........................................................................................................72.5.1传送机构的设计............................................................................................................72.5.2转盘的设计..................................................
