摘 要
    本课题来源于当今社会食品加工工业水果去皮设备的创新和更新换代基础之上，通过设计出水果去皮机，从而来满足当今社会水果去皮设备不足的缺陷。    
水果去皮机作为食品加工机械的一种，随着人们生活水平的提高，得到了越来越普遍的使用。它主要由机架、链传动机构、去皮体、传动轴等部分组成。通过电机带动链传动机构从而使去皮体转动，在内部刮刀与水平表面摩擦的情况下，实现水果的去皮。
本文运用理论联系实际的方法进行水果去皮机结构的研究，通过从水果去皮机的方案布局入手，查找相关资料，证明了本次设计的水果去皮机的结构方案的可行性，并对其中常用的标准件例如轴承，轴，链传动机构进行选型设计，最后进行各主要零部件的强度校核。

Abstract

    With the improvement of our living standard, single seat structure for baby dining table, leads to the limitation of interest in babies, which would in any country is a problem. How to solve this problem, which reflects the level of development of a society from the level of science and technology to the humanistic care and other aspects .
    China attaches great importance to the status of the degree is not enough, and the baby chair to drive innovation design, to achieve a "chair", to improve the above situation.Therefore, this paper carries on research on scheme selection. Through the professional knowledge of the designer to master the relevant information on the Internet, as well as the current situation at home and abroad, the design scheme, after a detailed investigation, this graduation design is to design a set of practical multifunctional baby chair..
    This design is begins with the argument, introduces in detail the scheme analysis, design process and calculating process, and has carried on the essential power of the overall structure of the system design. Mainly used for the realization of convenient for baby to eat, play, to further reflect the humane care.
