编号无锡太湖学院毕业设计(论文)题目稠厚物料灌装机构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)稠厚物料灌装机构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97学号0923836作者姓名2013年5月25日III摘要液料物料(简称液料)灌入包装容器的装置叫做灌装机或灌装设备。液料依自重即能灌入包装容器如油、酒、果汁、牛奶、酱油、墨水、糖浆、农药等也有的需要借助外界压力才能灌入包装容器,如番茄酱、肉糜、牙膏、香脂等。对于低粘度液料,根据是否溶解有二氧化碳气体而分为含气和不含气两类。对于含气液料,习惯上将不含酒精成分的,如汽水,可口可乐、矿泉水等,称为软饮料,而将含有酒精成分的分为如啤酒,汽酒、香槟酒等称为硬饮料。液料包装容器主要有玻璃瓶、金属灌,以及用塑料或柔性复合材料制成的各种杯、管、瓶、袋等。在我国目前仍广泛采用玻璃瓶装各类液料。这是因为,玻璃原料资源丰富、成本低、化学稳定性好、贮存期长,无毒、易清洗,可回收使用,尤其适合包装高档商品。而其主要缺点则是较重、破碎率高、搬运不便。因此,今后宜大力发展轻量瓶及液料软包装。采用铝质二片罐和铝质瓶虽能较好地克服玻璃瓶所在的缺点,但是它制造工艺复杂,成本高,在国内暂时难以迅速推广。至于塑料容器,如聚氯乙烯瓶,因含有毒性的氯乙烯单体,不宜用作食品包装容器,而聚乙烯或聚丙烯容器因其阻气性较差,也不宜灌装含气的和易氧化液料。现今,正致力于研制新型包装材料,如聚酯瓶、共挤复合瓶、复合包装盒等。采用机械化的灌装方法不仅可以提高劳动生产率,减少产品损失,保证包装质量而且还可减少生产环境和被灌装液料的相互污染。关键字灌装番茄机械化ⅣIVAbstractLiquidmaterialorliquiddeviceintocontainerscalledfillingmachineandfillingequipment.Theliquidmaterialaccordingtotheweightcanbepouredintocontainerssuchasoil,wine,fruitjuice,milk,soysauce,ink,syrup,pesticideothersneedthehelpofoutsidepressurecanbepouredintocontainers,suchastomatosauce,mincedmeat,toothpaste,balsam.Forlowviscosityliquidmaterial,accordingtowhetherthedissolvedcarbondioxidegasintogasandfreegastwo.Withthegasliquid,habits,nonalcoholicingredients,suchasCocaCola,softdrinks,mineralwater,knownassoftdrinks,andalcoholcomponentisdividedintosuchasbeer,champagne,sparklingwine,calledharddrinks.Liquidpackagingcontainerglassbottles,metalirrigation,andavarietyofcup,madeofplasticorflexiblecompositetubes,bottles,bagsetc..InChinaisstillwidelyusedinglassbottlesofvariousliquidmaterials.Thisisbecause,glassrawmaterialsrichinresources,lowcost,goodchemicalstability,longstorageperiod,nontoxic,easytoclean,recyclableuse,especiallysuitableforluxurygoodspackaging.Butitsmaindrawbackisheavy,highcrushingrate,inconvenienttransportation.Therefore,inthefuturetodeveloplightweightandliquidsoftpackage.Theuseofaluminiumtwocansandaluminumbottlecaneffectivelyovercometheshortcomingsofglassbottles,butitscomplicatedmanufacturingprocess,highcost,thetemporarilydifficulttospreadquickly.Asfortheplasticcontainers,suchasbottlesforPVC,vinylchloridemonomercontainingtoxic,shouldnotbeusedforfoodpackagingcontainers,andpolyethyleneorpolypropylenecontainersforitsgasresistanceispoor,notfillinggasandeasyoxidationliquid.Today,iscommittedtothedevelopmentofnewpackagingmaterials,suchaspolyesterbottle,bottle,coextrusioncompositepackagingbox.Thefillingmechanicalmethodnotonlycanimprovelaborproductivity,reduceproductloss,ensuremutualpollutionpackingqualitybutalsoreducetheproductionenvironmentandisfillingtheliquidmaterial.KeywordstomatopastemachineV目录摘要..........................................................................................................................................IIIAbstract................................................................................................................................................IV目录..................................................................................................................................................V1绪论...................................................................................................................................................11.1本课题研究的内容和意义...........................................................................................................11.2国内外的发展概况.....................................................................................................................21.3本课题应达到的要求..................................................................................................................32总体方案设计.....................................................................................................................................42.1主要组成结构............................................................................................................................42.2主要技术参数............................................................................................................................52.3工作原理与工作过程概述..........................................................................................................52.3.1稠厚物料灌装机的工作原理.............................................................................................52.3.2稠厚物料灌装机的主要工作过程......................................................................................83灌装和基本参数计算.........................................................................................................................113.1灌装........................................................................................................................................113.2灌装机的总体结构...................................................................................................................113.1.1灌装方法.......................................................................................................................113.1.2定量方法................................................................................
