I摘要粉料自动包装机是实现薄膜材料包装粮食等粉料产品的一种包装设备，广泛应用于食品、化工、医药、小五金等生产包装部门。随着人们对包装的需求多样化、人性化，粉料自动包装机的应用愈加普遍。目前国产的设备大多是对国外进口产品的简单仿制，因此针对粉料自动包装机关键部分的深入研究，对原理、结构、运动、功能等分析，提供结构简单可靠、操作方便、自动化程度高、使用范围广的包装机很有必要。本文在粉料自动包装机的包装工艺和使用要求的基础上，通过对关键部件的理论分析，提出一种使用简单、可靠和通用的传动系统，将单一包装尺寸拓展为袋长和产量可调的结构形式；对包装袋制造结构、装袋封口结构、传送结构等关键部件的设计原理、结构特点等做了较为详细的研究设计；本文分析各种机构的运动学规律，提出可行的优化结构满足包装工艺；对关键部件提出完整的设计方法，旨在满足市场需求，推动企业创新步伐。本文借助了AutoCAD、protel-DXP、MicrosoftOfficeVisio、keli等软件进行原理图绘制，流程图绘制，编写程序等。这种利用计算机作辅助设计和分析的方法，可以用于其他类型包装机设备的设计和分析中。关键词：自动包装机，封口系统，称重系统，包装工艺，计数显示系统IIDesignofAutomaticPowderMaterialPackagingMachineBasedonMCUABSTRACTPowderautomaticpackingmachineistherealizationofthinfilmmaterialssuchaspackagingoffoodproductsasapowderpackagingequipment,widelyusedfood,chemical,dailynecessities,medicine,hardwareandotherdepartments.Asthedemandforpackagingdiversification,personalization,automaticpowderpackagingmachineapplicationsmoregenerally.MostofthecurrentChina-madeequipmentisSimpleimportofimitationproducts,theautomaticpackingmachineforpowder-depthstudyofkeycomponents,thebasicprinciples,structure,movement,functionalanalysis,toprovideasimpleandreliablestructure,convenientoperation,highdegreeofautomationwithawiderangeofpackagingmachinesisnecessary.Basedontheanalysisofpowderpackingmachineautomaticpackagingprocessesandtheuseoftherequirementsonthebasisofthekeycomponentsofthetheoreticalanalysis,apractical,simple,reliableandversatiledrivesystem,asinglepackageforthebagtoexpandthesizeandoutputoflongadjustablestructure,fordeliveryofthefilmstructure,thestructureofclosedtraction,closed-endstructure,suchascuttingoffkeypartsofthedesignprinciples,structuralfeatures,suchasdoingamoredetailedstudyanddesign,ThispaperanalyzesthelawoftheKinematics,optimizingthestructureandputforwardfeasibletomeetthepackagingprocess,akeycomponentofacompletedesignmethod,designedtomeetthemarketdemand,Promotinginnovation.Inthispaper,usingtheautocad,pro-e,suchasmovementofsoftwareanalysisandstructuraldesign,suchastheuseofcomputer-aideddesignandanalysismethodscanbeappliedtoothertypesofpackagingequipmentdesignandanalysis.KEYWORDS:automatic,packingmachine,packingsealingsystem,weighingsystem，CountingdisplaysystemIII目录前言..................................................................................................1第1章绪论....................................................................................21.1粉料自动包装机控制系统发展情况....................................21.1.1国外发展情况.............................................................21.1.2国内发展情况.............................................................21.1.3我国包装机控制系统的发展方向...............................31.2粉料自动包装机控制系统的应用及适用范围....................31.3粉料自动包装机控制系统现存问题....................................31.4研究开发的意义...................................................................41.5研究的内容与目的...............................................................51.5.1研究内容.....................................................................51.5.2研究目的.....................................................................51.6本章小结...............................................................................5第2章粉料自动包装机控制系统总体方案设计............................72.1粉料自动包装机控制系统的组成和各部分的功能..............72.2粉料自动包装机控制系统总体方案.....................................82.2.1设计要求和适用范围.................................................82.2.2工艺流程分析.............................................................92.2.3设计步骤...................................................................122.3本章小结.............................................................................13第3章粉料自动包装机控制系统硬件设计..................................143.1硬件选型..............................................................................143.1.1封口模块元件设计...................................................143.1.2装料模块元件设计...................................................153.1.3称重模块元件设计...................................................163.1.4光电检测模块元件设计............................................173.1.5放大电路元件设计...................................................183.1.6显示模块元件设计...................................................203.1.7主处理器的选用.......................................................21IV3.2粉料自动包装机控制系统的原理图设计...........................223.3本章小结.............................................................................23第4章粉料自动包装机控制系统软件设计..................................244.1keil软件简介.......................................................................244.2软件设计.............................................................................254.2.1包装袋制作系统的程序分析....................................254.2.2数码管显示程序分析...............................................264.2.3MAX485与单片机间数据传递程序分析.................274.3本章小结.............................................................................29第5章系统调试.............................................................................305.1Keil软件调试......................................................................305.2Protel-Dxp软件的介绍.......................................................315.3Micr
