设计简介
摘 要：红薯具有很高的营养价值和很好的味道，很多人们喜欢吃。随着人们的生活水平越来越高，对红薯的食用要求也越来越高。例如在食用红薯的时候要将其切成丝或片，因而切片机应运而生。本文设计的切片机主要针对中小型场合，例如加工作坊、食堂、家庭等。本设计针对红薯茎块的形状而设计的。本文分别对带、轴、刀片、刀盘等进行设计计算，对轴承、键等元件进行了选择。本设计的切片机有较高的效率，能对红薯茎块等进行工作。

Abstract: The sweet potato has a high nutritional value and taste good ,a lot of people like to eat. With the development of economy, the standard of sweet potato for people is getting higher and higher. For example，people cut the sweet potatoes into pieces when they want to eat it. so the slicing machine born. the slicing machine designed in this paper uses at some small and medium-sized places, such as the workshop、canteen and household. The slicing machine is designed based on the tuber crops of sweet potatoes . In this paper，the tape、axis、blade and cutter disk are designed and calculated and the components of axle bearing and bond are selected. The design of the slice machine has a high efficiency when it works on the sweet potato tubers.
