Design Of Automatic Machine Of Lotus Seed's Spiltting

Lotus seeds splitting is an important link of lotus seed preliminary working, the traditional manual split and semi-automatic splitting way, existing labor intensity, low efficiency and production of high risk, which has been already unable to adapt to the need of lotus large-scale production. In order to meet the high quality requirement, as the research object of lotus automatic machine of lotus seed's splitting, this paper on the basis of consulting the lotus development status and dynamic related at home and abroad,have researched the calculation of splitting force, analysed the splitted processing and numerical simulation of finite element, solutions of splitting, mechanism of design, self-centering technology research, and virtual prototype design and assembly, motion simulation analysis research.This paper mainly expound as follows:(1) surveyed the lotus geometric parameters and parting surface area. established a mechanical model, calculated formula of splitting force, verified the splitting force of theoretical formulas by experimental; simulated the splitting process with ANSYS software of a finite element analysis tools.(2) according to the requirements of lotus splitting and the splitting force measured by experiment, put forward the design schemer of Automatic Machine of Lotus Seed's Splitting , realize the mechanical action like automatic blanking, feeding, splitting, back and discharging, etc. It can satisfy the automation requirements.(3) Based on the geometric feature size of lotus , combine the special form roller chain and globular indexing CAM, to realize the self-centering, ensure lotus axis on splitting position and thimble axis coaxial.(4) have designed the transportation agency, CAM agency, splitting institutions, next makings institutions and other related agencies; Completed the CAM motion circulation chart matching design, guarantee each action coordination in the splitting process.(5) based on UG software ,have created indexing CAM, plane CAM, splitting institutions and other related parts, conducted the virtual assembly of 3d model; Create the virtual prototype of Automatic Machine of Lotus Seed's Splitting, and carries the motion simulation analysis, get the displacement, velocity and acceleration rule, provides reference for correct evaluation the performance of machine.
