PAGEVIII摘要首先针对卷筒纸胶印机进行总体方案设计，进而确定卷筒纸胶印机的总体布局，随后，对卷筒组件进行设计。介绍了卷筒的工作原理及关键技术。然后，确定了合理的卷筒总体结构，分别对卷筒的各零部件作了设计，产生了装配图、零件图与设计说明书等设计文档。最后，对卷筒的旋转轴和轴承进行了详细的分析和校核，计算表明，该卷筒设计符合要求。本课题是以卷筒纸胶印机为基础，参考目前市场上常用的卷筒纸印刷机进行设计，对滚筒和离合压的等常用结构进行设计。通过参考同类机器的设计实现印版和橡皮布的装卡和锁紧、滚筒之间的离合压及调压；滚筒的转动可实现手动和电动；离合压机构可以使用手动和气动两种形式。印版滚筒的装卡机构采用窄缝式，橡皮布的装卡采用夹板式；离合压、调压采用单偏心机构。并用SolidWorks软件建立了卷筒纸胶印机印刷装置实体模型。关键词：卷筒纸胶印机，印刷装置，实体AbstractFirstly,theoverallschemedesignforweboffsetprintingmachine,whichwilldeterminetheoveralllayout,weboffsetprintingmachinethen,carriesonthedesigntothespoolassembly.Thispaperintroducestheworkingprincipleandkeytechnologyofroll.Then,thedrumstructurereasonable,thedrumpartsweredesigned,producedtheassemblydrawing,partdrawingandthedesignspecificationanddesigndocuments.Finally,ontherotationofthedrumshaftandbearingareanalyzedandchecked,detailedcalculationshowsthat,thedrumisdesignedtomeettherequirementsof.Thistopicisweboffestpressbasedonthemarketatpresent,referencecommonlyusedwebprintingmachinedesign,carriesonthedesigntothecommonstructureofcylinderandclutchpressure.Clutchbyreferencetosimilarmachineimplementationoftheplateandblanketclampingandlocking,drumpressureandpressure;therotationoftherollercanrealizemanualandelectric;theon-offpressuremechanismcanusemanualandpneumatictwoforms.Aprintingplatecylinderclampingmechanismadoptsanarrowslittype,blanketclampingthesplint;clutchpressure,pressureregulatingsingleeccentricmechanism.AndtheestablishmentoftheweboffsetprintingdeviceofsolidmodelinSolidWorkssoftware.Keywords:weboffsetprintingdevice,entities目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc388651328"摘要PAGEREF_Toc388651328\hIIHYPERLINK\l"_Toc388651329"AbstractPAGEREF_Toc388651329\hIIIHYPERLINK\l"_Toc388651330"第1章绪论PAGEREF_Toc388651330\h1HYPERLINK\l"_Toc388651331"1.1概述PAGEREF_Toc388651331\h1HYPERLINK\l"_Toc388651332"1.2印刷机分类PAGEREF_Toc388651332\h1HYPERLINK\l"_Toc388651333"1.3印刷机的构造PAGEREF_Toc388651333\h6HYPERLINK\l"_Toc388651334"1.3.1印刷机滚筒PAGEREF_T
