多功能切菜机设计

摘要

蔬菜是人体必需的一种营养成分，食用的方式更是多种多样。因此把蔬菜加工成各种形状，如条状、片状等样式，单靠人工来完成既费时费力又不好加工。目前，多功能切菜机大多数都是价格比较昂贵的大型设备，不适合农民、个体、小型工厂的食品加工和生产。为了克服这样的缺点，本次设计在查阅了大量相关材料的基础上，进行多功能切菜机的设计，经过各种理论计算、校核，设计了一种小型多功能切菜机。主要由进料斗、下料斗、切削刀、刀盘及电动机组成，其工作的原理是利用根茎类蔬菜的重力作用实现进料，通过切削刀旋转将下料斗中的蔬菜切成片状或丝状，最后成品从出料口出来。实现了能够连续进料和出料，可调节形状、大小尺寸，具有生产效率高、功耗低、加工质量好等多个优点。

本次的设计就是多功能切菜机的设计，通过对多功能切菜机进行结构设计，以及其中的标准件进行选型设计，大大提高了它的稳定性。相信此次设计的多功能切菜机的出现将会大大提高食品菜肴的自动化程度和质量，为食品工业的生产以及人民生活水平的提高能够带来显著的进步，同时也在一定的程度上推进了机械工业的持续发展。

Abstract

Vegetables are a kind of food that the human body needs, and it is a variety of methods. So to the processing of vegetables into a variety of shapes, such as bars, sheets, etc.a manual to complete the process is time-consuming, laborious and not good processing. At present, machine for large expensive equipment, does not apply to individual farmers production and small factories in the food processing; in order to overcome the disadvantages, this design in access to a large number of relevant references based on, shredder machine design, through theoretical calculation and checking, design a small multifunctional cutting machine. The machine is mainly composed of a feed hopper, the hopper, cutting knife, cutter and the motor composition and its working principle is the free fall of the root vegetables can feed, through the cutting knife rotating the hopper in the vegetable slicing and shredding and finally finished by the material discharging mouth.

Realize the continuous feeding and discharging, film thickness, wire thickness adjustable function, with high productivity, low power consumption, safe and reliable, good processing quality, etc..In the design, driving roller type conveyer manufacture and application, at present our country compared with foreign advanced level there are still large gaps, domestic in the design and manufacture of driving .This design is the optimization design of driving roller conveyor.
