摘要颗粒包装机一般适用于食品、医药、茶叶、化工、等产品中松散状、无粘性、细小的颗粒物品的小剂量自动包装，主要由包装材料输送机构、成型机构、封口机构、送料机构、切断机构、机架等组成，具有操作简单、生产量大、适用范围广等特点。本设计进行了颗粒包装机的设计方案论证、包装原理分析、机械结构设计和强度计算等，设计的颗粒包装机主要由供料料斗、计量供料、包装薄膜供给、成型、纵封、横封、定量供料器、切断、电器加热等组成，其工作原理是薄膜卷装在可调节轴向距离的轴上，薄膜经张紧装置、导向滚筒、牵引滚筒进入薄膜导向成型器，形成对折的U形结构。进而，纵封辊将薄膜横封成筒状，横封辊将筒状薄膜的底部封口，制成敞口袋，供料机构向敞口袋内充填物料，然后横封辊将敞口袋的口封合，切割装置的切刀将连续包装袋切成单袋，完成包装过程。本机具有整体性好、运动精度高、工作效率高、安全可靠、操作容易、制造成本低等特点。关键词：颗粒包装机；结构设计；袋成型；纵封；横封。ABSTRACTGranulepackingmachineisgenerallyusedinfood,medicine,tea,chemicals,andotherproductsinlooseform,non-sticky,tinyparticlesgoodsinsmalldosesautomaticpackaging,mainlybythepackagingmaterialtransportmechanism,formingmechanism,sealingmechanism,feedmechanism,cuttinginstitutions,racks,etc.,withsimpleoperation,productioncapacity,wideapplicationandothercharacteristics.Thisdesignmakespackingmachinedesignargument,packagingprincipleanalysis,mechanicaldesignandstrengthcalculation,particlepackingmachinedesignedmainlybythesupplyhopper,meteringfeed,packagingfilmsupply,molding,longitudinalsealing,transversesealing,quantitativefeeder,cutting,heatingandotherelectricalcomponents,itsworkingprincipleismountedonanadjustablefilmreelshaftaxialdistance,thefilmbythetensioningdevice,theguiderollers,tractionrollerguideintothefilmformingdevicetoformafoldedU-shapedconfiguration.Further,thelongitudinalsealingrollerstransversesealingthefilmintoatubularshape,transversesealingthetubularfilmrollatthebottomoftheseal,madeofopenpocket,toopenthebagfeedingmechanismforfillingmaterial,andhorizontalsealingrollerssealthemouthofthepocketopen,cuttercuttingdeviceintoacontinuousbagsinglebag,completepackagingprocess.Themachinehasgoodintegrity,highprecision,highefficiency,safetyandreliability,easyoperation,andlowmanufacturingcosts.KEYWORDS：Granulepackingmachine;structuraldesign;bagsmolding;longitudinalsealing;transversesealing.目录摘要.......................................................................................................................iABSTRACT.............................................................................................................ii目录.....................................................................................................................iii1绪论......................................................................................................................11.1包装机械的作用.......................................................................................11.2包装机械的分类.......................................................................................11.3颗粒包装机械的组成...............................................................................21.4颗粒包装机械的发展趋势.......................................................................22颗粒包装机总体结构方案设计..........................................................................42.1颗粒包装机设计参数.......................................................................
