负压灌装机设计毕业论文.doc

本科生毕业设计(论文)I摘要随着人们生活水平的提高,灌装饮料由于它的方便、口味多样、便宜日益被人们所接受。从此灌装机便越来越受到商家的青睐。本论文要介绍的就是负压式自动灌装机。负压式自动灌装机就是在密闭的灌装容器上有一支真空管通至真空泵。在灌装容器上腔施以的低真空气压,容器内的空气经工作头回气管被抽出,此时容器内气压与灌装缸上腔气压相等,液体在负压的作用下对容器进行充填。由于负压的作用,灌装时不会出现液体泄露的现象。本机器采用的是整体式液箱,箱内有插槽,每个插槽都对应一定的容积,在更换容积时只须将插板插入相应的插槽内,即可实现换液。传动部分主要由齿轮组成,因为齿轮有传动精度高,使用寿命长的特点,避免了因频繁更换零件而出现工位误差的缺点。本灌装机的设计可以实现灌液容量的可调。有较高的效率、可靠性和可维修性。关键词灌装机负压式灌液本科生毕业设计(论文)IIAbstractAsthepeopleslivingdeveloped,Itisconvenientthankstofillingpackingthebeverage,Personstasteisdiversified,Cheaplyreceivedbypeopleincreasingly。ThereupontheFillingpackingmachinesimplyismoreandmoregracesofbusiness.ThisdissertationwillbeintroducedTheminupressautomaticallycontrolledfillingmachine.Theminupressautomaticallycontrolledfillingmachineisavacuumvalvetogotoonthecontainerpackingtillthevacuumpumponthehermeticallyfillingpackingcontainer.Onthefillingpackingcontainerbeinglivingthecavityexecuteswithcoarsevacuumatmosphericpressure,Theairinthecontainergoesbackthatthetracheaistakeoutaftertheworkhead,Theatmosphericpressureincavityisequaltotheinnerplacethecontainer,Theliquidislivingtocarryonthebacktofilltothecontainerbelowtheactionwhichisgettingnear,Thismachineryadoptsisthatthefluidboxisentirestyle,Thereistheslotinthebox,Whollyhomologousspecifiedvolumeofeveryoneslot,Beinglivingwillmerelythrusttheplankwhenreplacingthevolumetostickininnerplacetherelevantslot,Inimmediatefuturemayachievetradesfluid.Thedrivesectionismainandconsistsofthegear,Forthegearpossessthehighdriveaccuracy,Servicelifelonglythatdevelopsdistinguishingfeature,Averthavingraisedpositionerrordefectasaresultoffrequentlyreplacingthespareparts.Thismachinesmeasuringcupisadjustable,soitcanmeetvariousvolumebottlefilling.Inaddition,thisbottlefillingmachinealsohasthreetraitshighefficiency,plumyreliabilityandmaintainability.KeywordFillingMachineMinupressureFilling本科生毕业设计(论文)III目录第1章绪论...........................................................................................................11.1毕业设计的目的........................................................................................11.2毕业设计的主要技术参数和要求............................................................11.2.1主要参数.........................................................................................11.2.2要求.................................................................................................11.3负压式灌装机的应用价值及设计意义....................................................11.3.1能增加花色品种,改善产品质量,加强市场竞争能力.............21.3.2能改善劳动条件,避免污染危害环境.........................................21.3.3能节约原材料减少浪费,降低成本.............................................21.3.4能提高生产效率,加速产品的不断更新.....................................21.4负压式灌装机的发展水平........................................................................2第2章负压式灌装机的总体方案设计.................................................................32.1工艺方案设计............................................................................................32.2机器的总体布局........................................................................................32.3传动方案设计............................................................................................42.4执行机构的方案拟订................................................................................52.4.1工作头.............................................................................................52.4.2液体容量的调节方法.....................................................................62.4.3液面的控制方法.............................................................................62.4.4液箱高度的调节方法.....................................................................72.4.5气缸和气阀的控制方法.................................................................72.4.6工作台的控制方案.........................................................................72.4.7进出拨轮的设计方案.....................................................................82.5控制方式选择............................................................................................82.6传动方案的选择........................................................................................82.7气源的选用................................................................................................8第3章传动系统设计计算...................................................................................103.1运动与动力参数设计计算......................................................................103.1.1类比法选择动力源.......................................................................103.1.2总传动比及传动比的分配...........................................................103.1.3各轴参数的计算...........................................................................113.2传动零件设计计算..................................................................................133.2.1带的选择和校核...........................................................................13本科生毕业设计(论文)IV3.2.2齿轮的确定和校核.......................................................................163.2.3Ⅳ轴的较核.................................................................................193.2.4轴承的较核....................................................................
