全自动杀鱼机设计

中国计量学院毕业设计(论文)I全自动杀鱼机设计摘要:全自动杀鱼机，主要对一般食用鱼类进行刮鳞、剖腹、挖肠、清洗等前期自动化处理。本文旨在基于PLC控制技术，以及先进光电检测方法，设计一台根据鱼类不同可实现自主调节的杀鱼机。本文主要包括杀鱼机空间结构设计、鱼头夹持部件设计、鱼尾夹持部件设计、刮鳞部件设计、剖腹部件设计、挖肠部件设计以及清洗部件设计。由于鱼类大小不一，杀鱼机基于光电检测技术和PLC控制技术设计完善的鱼体检测运送方案，该方案集鱼体检测、运送于一体，同时确定后续处理的工作行程，方便快捷，实用可靠。由于杀鱼机是对活鱼进行处理，鱼体必须进行固定，在鱼的夹持固定方案中采用鱼头、鱼尾双夹持的方案。结合相应的控制保证了后续刮鳞、剖腹等处理的顺利进行。针对鱼体厚度的不同，在刮鳞部件的设计中采用了弹性设计方案，该方案部件工作过程中，滚筒始终紧贴鱼体，并保持相对压力，轻松将鱼鳞刮除，同时保证不损伤鱼体。在剖腹部件中，设计一个V形保持架，剖刀与保持架保证相对位置。这使得剖刀在保持架帮助下沿鱼腹中线将鱼体剖开。整机控制器选用了日本三菱公司NFX2的系列的可编程控制器，它具有可靠性高、抗干扰能力强、实用性和通用性强的优点。关键词:全自动杀鱼机；鱼头、鱼尾夹持部件；剖腹部件；挖肠部件。中国计量学院毕业设计(论文)IIThedesignofautomaticfishkillingmachineAbstract:Automaticfishkillingmachine,mainlyonthegeneralconsumptionoffishscalestoscratch,laparotomy,intestinaldigging,cleaningandotherpre-processedautomatically.ThestudyisbasedonthePLC-basedcontroltechnology,andadvancedoptoelectronicdetectionmethods,todesignanautomaticfishkillingmachine,witchcandealdifferentfishundertheself-regulated.Inthearticle,thereareincludingthedesignofspatialstructureofmachine,thedesignofpartsgripperhead,thedesignoffishholdingparts,scrapingscalespartsdesign,partsdesignsection,dugintestinalcleansingcomponentdesignandcomponentdesign.Sincethesizesoffish,theAutomaticfishkillingmachinebasedonthephotoelectricdetectiontechnologyandPLCcontroltechnologydesignedtoimprovethedeliveryoffishdetectionprogram.Inthisprogram,fishtestingprogramanddeliveryworkstogether,atthesametimeworkingtodeterminefollow-upvisit,convenient,practicalandreliable.SincetheAutomaticfishkillingmachineforprocessingfish,fishmustbefixed.Itchoosestheprogramwitchboththeheadandfishtailfixedclamping,withthecontrolcombinedwiththecorrespondingfollow-up,toensurethatscratchthescalesofthesectiondealingwiththesmoothconductofsuch.Aflexibledesignusedinthedesignofscrapingscalesforthethicknessforthedifferentfish.Inthisprogram,thedrumhasalwaysbeenclosetofishandtomaintaintherelativepressure,easytoscalecurettage,atthesametimetoensurethatfishdonotdamageduringcomponentsprocess.IntheSectioncomponents,aV-shapedcageisdesigned,autopsyknifetoensureandmaintaintherelativepositionsofaircraft,whichhelpthepost-mortemknifecutopenthefishinmaintainingtheaircraftalongthemidlinetofish.MachinecontrollerselectedMitsubishi'srangeofprogrammablelogiccontroller,whichhashighreliability,stronganti-interferenceability,practicalityandtheadvantagesofhighuniversality.Keywords:Automaticfishkillingmachine；thehead,tailclampingcomponents;sectioncomponents;dugintestinalparts中国计量学院毕业设计(论文)III目次摘要···············································································································Ⅰ目次···············································································································Ⅲ1.前言·············································································································11.1国内外发展状况·····························································································11.全自动杀鱼机设计思路······················································································31.3全自动杀鱼机设计准则····················································································41.4全自动杀鱼机设计意义····················································································52.机械结构及工作原理设计···················································································62.1机械结构及工作原理设计·················································································52.1.1整机机械结构空间布置设计···········································································62.1.2整机结构及工作原理设计··············································································72.1.3杀鱼机鱼体大小检测原理设计········································································82.2杀鱼机机械零部件设计····················································································92.2.1鱼头夹持部件的结构及工作原理设计·······························································92.2.2鱼尾夹持部件的结构及工作原理设计·····························································102.2.3刮鳞夹持部件的结构及工作原理设计·····························································122.2.4剖腹部件的结构及工作原理设计···································································132.2.5挖肠部件的机构及工作原理设计···································································152.2.6清洗部件的机构及工作原理设计···································································153.控制电路设计·······························································································163.1全自动杀鱼机控制时序··················································································163.2鱼身夹持控制原理························································································163.3刮鳞控制原理······························································································173.4剖腹、挖肠控制原理·····················································································183.5杀鱼机控制器选择························································································194.机械设计计算·······························································································21中国计量学院毕业设
