编号无锡太湖学院毕业设计(论文)题目液体灌装生产线上拧瓶盖机的设计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日摘要回转式拧瓶盖机适用于带螺纹的盖与瓶的旋盖,市场上现有的回转式拧瓶盖机大多数是半自动的包装机,瓶盖的疏理大多由人工来完成,生产效率不是很高,而且加大了劳动的强度,再生产时有一定的危险,本设计为自动理盖而且是多工位拧盖机。本文介绍了题目的研究背景和意义,论述了拧盖机在国内外的发展状况,介绍了本次设计研究的内容及方法。本次设计的重点是拧盖机的总体设计方案、过程的拧盖、输送方式和定位方法,在此基础上进行了运动与结构的设计。本次设计采用的拧盖方法是回转式的,是通过圆柱凸轮的轮廓线来实现拧盖头的上下往复运动的,通过锥齿轮传递转矩而且在满足拧盖机原理的条件下,充分考虑了整机的布局和经济性,不但结构简单明了,操作方便而且本课题的设计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。关键词拧瓶盖机构理盖机构传送自动化转盘IIAbstractRotaryCappingMachineforthethreadedcapandthebottleofscrewcap,astheexistingrotarycappingmachinesaremostlysemiautomaticpackagingmachine,bottleofReorganizingtheemployertocompletemostoftheproductionefficiencyisnotveryhighandincreasedlaborintensity,haveacertainriskofreproduction,thedesignfortheautomaticmanagementisamultipositioncapandscrewcap.Thisarticledescribesthebackgroundandsignificanceoftheresearchtopicsdiscussed.Capperdevelopmentathomeandabroad,introducesthedesignofthisstudythecontentandmethods.Thepackagingmachineisdesignedtofocustheoveralldesignscheme,thepackagingprocessofscrewingconveyancemethodsandpositioningmethods,inthisbasedonthemovementandstructuredesign.Thedesignofthepackagingusedisrotary,throughcylindricalcamcontourtoachievecappingheadupanddownreciprocatingmotionthroughtheplanetarygeartransmissiontorqueandpackagingmachinerytomeettheconditionsofprinciple,givefullconsiderationtothemachinelayoutandtheeconomy,whilemachineisalsosimple,lowcost,nopollution,noiseandhumanandfunctionalcharacteristicsofreasonable.KeywordsCappjingMachinecancellingmachinedeliverautomationturntablIII目录摘要..................................................................................................................................................IAbstract..........................................................................................................................................II1绪论.............................................................................................................................................11.1本课题的研究内容和意义...............................................................................................11.2国内外的发展概况...........................................................................................................11.3本课题应达到的要求.......................................................................................................12总体方案设计.............................................................................................................................22.1方案一的介绍...................................................................................................................22.2方案二的介绍...................................................................................................................22.3方案比较...........................................................................................................................22.4采用方案的详细设计.......................................................................................................32.4.1上盖装置的设计.....................................................................................................32.4.2传送带的设计.........................................................................................................42.4.3底座箱的设计.........................................................................................................42.4.4拧盖机构的设计.....................................................................................................42.4.5转盘的设计.............................................................................................................53总装图的确定.............................................................................................................................63.1主要技术参数的确定.......................................................................................................63.1.1电机的选择.............................................................................................................63.2传动方案的确定...............................................................................................................73.3结构方案的确定...............................................................................................................74部件装配图的确定.....................................................................................................................94.1带传动的计算...................................................................................................................94.2轴的设计计算和校核.....................................................................................................114.2.1轴的结构设计及选材...........................................................................................114.2.2轴的设计计算.......................................................................................................114.2.3轴的校核计算.......................................................................................................124.3齿轮的计算和校核.............................................................................
