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 N FX 2 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) II The design ofa utomatic fish killing machine Abstract: Automatic fish kill ing machine, mainly on the general consumption of fish scales to scratch, laparotomy, intestinal digging, cleaning and other pre-processed automatically . The study is based on the P LC-based control technology, and advanced optoelectronic detection methods , to design ana utomatic fish kill ing machine , witch can deal different fish under the self-regulated . In the article, there are including the design of spatial structure of machine, the design of parts gripper head, the design of fish holding parts, scraping scales parts design, parts design section, dug intestinal ponent design ponent design. Since the sizes of fish, the Automatic fish kill ing machine based on the photoelectric detection technology and PLC control technology designed to improve the delivery of fish detection program . In this program , fish testing program and delivery works together , at the same time working to determine follow-up visit, convenient, practical and reliable. Since the Automatic fish kill ing machine for processing fish, fish must be fixed . It chooses the program witch both the head and fish tail fixed clamping , with the c bined with the corresponding follow-up , to ensure that scratch the scales of the section dealing with the smooth conduct of such . A flexible design used in the design of scraping scale s for the t hickness for the
