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: Packer is the use of waste paper banding around the product or package, and then tighten up both ends and melt through the thermal effect or the use of materials such as packet buckle connected to the machine. Packer's function is to enable the plastic band can be tied closely to the surface of the package to ensure that packages in the transportation, storage isnot a result of unsound and scattered Banding, banding should be attractive and tidy. Using the five-loop, push the paper loop pressure paper loop wire loop folder. Loop cut into shreds. Paper balers hydraulic system by hydraulic cylinder, dual one-way throttle valve, pilot controlled check valve, ic valve, relief valve, throttle, coolers, earthquake-resistant pressure gauge, pressure hose , unloading valves, ic relief valve, check valve, vane pump, coupling, motor, back to the oil filter, air filter, fuel tank level gauge and soon. Paper balers hydraulic action request is the first paper will be pushed to the designated location of paper, and then paper will be pacted paper, and then wire agencies, and institutions folder silk, will be paper, cut wire will break. Into the next cycle. Key words: Hydraulic cylinder, dual one-way throttle valve, pilot controlled check valve, ic valve, relief valve, etc. 目录引言................................................................................................................................ 1 1液压系统的技术要求和工况分析............................................................................. 1 技术要求............................................................................................................. 1 负载分
