一种小型家用磨面机的设计研究

摘要

A small low speed milling machine has been designed for household use.The device adopts vertical roller mill grinding,and is equipped with the outer cylinder rotation drive screw lift to achieve a uniform grinding mechanism which ensures the produced flour's nutrition structure intact.The function structure and working principle of the mill,the kinematics theory of the roller mill and the lifting mechanism are applied.A new structure of the whole machine as well as its key parts has been performed.The software EDEM has been used to carry out the simulation of the particle transport of flour,and the factors which affecting the efficiency of material conveying have been studied.Thus this study provides reference for the selection of the motor and the design of the whole machine.%设计了一款适合家用的小型多功能磨机,该装置采用立辊磨的磨制形式,同时配有外筒旋转驱动螺旋提升机构,能够实现磨粉均匀.针对磨机进行了功能结构及工作原理的介绍,以及立辊磨和提升机构运动学理论研究.对整机及其关键部件进行了结构设计.对外筒驱动的螺旋提升机构进行了面粉颗粒物料EDEM输送模拟仿真,研究物料输送效率影响因素,为磨机电机选型及整机设计提供参考.
