文档介绍：摘要:废纸打包机是使用捆扎带缠绕产品或包装件,然后收紧并将两端通过热效应熔融或使用包扣等材料连接的机器。打包机的功用是使塑料带能紧贴于被捆扎包件表面,保证包件在运输、贮存中不因捆扎不牢而散落,,推纸回路,压纸回路,送丝回路,、双单向节流阀、液控单向阀、电磁换向阀、减压阀、节流阀、冷却器、耐震压力表、测压软管、卸荷阀、电磁溢流阀、单向阀、叶片泵、联轴器、电机、回油过滤器、空气滤清器、液位计和油箱等组成。其动作要求是首先推纸机构将纸推到指定位置,然后压纸机构将纸压实,随后送丝机构送丝,同时夹丝机构夹丝,将纸包裹紧,切丝机构将丝切断。进入下个循环。关键词:液压油缸、双单向节流阀、液控单向阀、电磁换向阀、减压阀等Abstract:Packeristheuseofwastepaperbandingaroundtheproductorpackage,'sfunctionistoenabletheplasticbandcanbetiedcloselytothesurfaceofthepackagetoensurethatpackagesinthetransportation,storageisnotaresultofunsoundandscatteredBanding,-loop,,dualone-waythrottlevalve,pilotcontrolledcheckvalve,icvalve,reliefvalve,throttle,coolers,earthquake-resistantpressuregauge,pressurehose,unloadingvalves,icreliefvalve,checkvalve,vanepump,coupling,motor,backtotheoilfilter,airfilter,,pactedpaper,andthenwireagencies,andinstitutionsfoldersilk,willbepaper,:ylinder,dualone-waythrottlevalve,pilotcontrolledcheckvalve,icvalve,reliefvalve, 11液压系统的技术要求和工况分析 12拟订液压系统原理图 33液压缸的设计与计算 (采用45钢) (材料为45钢) (采用45钢) 、切丝液压缸设
