I摘要毕业设计的题目是易拉罐封盖机设计，主要用于罐装生产线上的易拉罐封盖。能够实现生产线上高速、自动化生产。易拉罐封盖机工作过程主要包括：自动加盖、传送易拉罐和封盖三个部分。整机分为三部分：机械部分、气动部分和控制部分。机械部分包括传送部分和封盖部分的设计。传送部分主要是对传送装置中，传送带的设计以及整个传送装置的支架的设计。气动部分包括：气源的选择、气缸的选择和气动辅助元件的选择。自动加盖器是以气缸为动力源，传送部分以电动机为动力源，封盖部分是电机与气缸联合完成的。控制部分采用了PLC控制。本设计的特点，所设计的易拉罐封盖机能通过PLC自动快速完成封盖动作，效率高，密封性好，自动化程度高。关键词：易拉罐；封盖机；PLCIIAbstractGraduationdesigntopiciscanssealingmachinedesign,mainlyusedincannedcanssealingsystemontheproductionline.,canmaketheproductionline,high-speedautomation.Canblockmachineworkingprocessinclude:automaticbuild,transmitcansandcappingthreesteps.Themachineisdividedintothreeparts:mechanicalparts,pneumaticpartsandcontrolparts.Mechanicalpartsincludingthedesignofthetransmissionpartandsealingpart.Transmissionpartismainlytothedesignoftransmissiondeviceintheconveyorbeltandthetransmissionofstentdesign.Pneumaticpartincludes:thechoiceofairsupply,selectionofcylinderandpneumaticauxiliarycomponentselection.Automaticcappingmachineisacylinderforpowersupply,transmissionpartsformotorpowersource,isjointlycompletemotorandcylinderblocksection.ControlpartadoptsthePLCcontrol.Thisdesignfeatures:canssealingsysteminvolvedinthefunctionblockbyPLCautomaticrapidaction,highefficiency,goodsealing,highdegreeofautomation.目录第1章绪论............................................................................................................11.1概述................................................................................................................11.2研究的意义....................................................................................................2第2章封盖机构的设计........................................................................................32.1运动与动力参数的设计计算........................................................................32.2带传动设计....................................................................................................52.3带的结构设计................................................................................................62.4封盖气缸选择................................................................................................72.5传送易拉罐气缸选择....................................................................................82.6轴的设计计算................................................................................................92.7滚动轴承的选择和寿命验算......................................................................152.8键连接的选择和验算..................................................................................162.9轴承盖设计..................................................................................................17第3章传送机构设计..........................................................................................183.1传送带设计..................................................................................................193.2槽轮机构......................................................................................................203.3联轴器选择...........................
