摘  要

本毕业设计为家用小型磨面机，题目的来源是生产和生活需要所发现。这次的设计通过分析理解以前的人研究的理论基础，还有研究形状、及其各种物理特性，以及在工作过程中的受力分析，磨头，筛粉箱等结构的基础上，进行改造升级，极大的提高磨面机的效率和机械性能。

磨面机，我们在生活中又把他叫做面粉机，原粮磨面机，磨面机，打粉机，制粉机，小麦磨面机，五谷杂粮面粉机，钢磨面粉机，玉米面粉机，皮面分离机，等等好多名字，本次设计的磨面机相比较原有磨面机：结构比较简单、可单人操作加工，安装方便，体积小，操作使用方便，它的扭矩相对也是比较小的，另外不容易粘结面粉。它由进料系统、磨头磨面系统和麸皮面粉分离统组成。当它工作的时候：首先圆锥形磨头将原料磨碎，磨头是通过带传动带动的，磨头的主轴由两个安装在机架上的轴承座进行支撑，同时磨头的间隙这里设计的可以调节，由磨面机端的调节手柄调节完成，通过调节手柄挤压磨头主轴，减小磨头之间的间隙，从而调节面粉的粗细，然后磨碎的粮食直接从磨头间隙经罗架落到罗底上，由可调整间隙的刷子与罗底将面粉与麸子（种皮）分离开。这台机器可以加工种类有小麦、大米、小米、玉米、黄豆、芝麻、大豆、高梁、青稞等粮食类产品。

Small Surface Mill Design

Abstract

This graduation design is a small household surface mill, the source of the topic is the production and living needs found. This design through the analysis and understanding of the theoretical basis of previous human research, and the study of shape, and its various physical characteristics, as well as in the work of in the process of force analysis, grinding, powder box and other structures on the basis of transformation and upgrading, greatly improve the efficiency and mechanical performance of the mill.

In mill, we called him flour mill, raw flour mill, mill, flour mill, flour machine, flour machine, wheat mill, grain flour mill, steel flour mill, corn flour mill, leather flour separator, and so on a lot of name, the design of the mill compared to the original mill: structure is simple, single operation processing, convenient installation, small size, easy to use, its torque is relatively small, it is not easy to bond flour. It consists of feeding system, grinding system and bran separation. When it works: first conical grinding raw material, grinding head is driven by belt drive, grinding the spindle supported by two installed on the frame of bearing, at the same time the gap here design can be adjusted, adjusted by the mill end handle adjustment, by adjusting the handle extrusion grinding spindle, reduce the gap between the spindle, to adjust the thickness of the flour, and then ground grain directly from the frame to the bottom, by the adjustable clearance of the brush and bottom will flour and bran (skin). The machine can process wheat, rice, millet, corn, soybeans, sesame, soybean, sorghum, highland barley and other grain products.

Key words:Mmill; cone mill; separation system, mill head
