摘 要
本文主要介绍了 MR141毛刷式锯齿剥绒机的总体设计、锯筒部和工作箱部设计。MR141型毛刷式锯齿剥绒机专为从轧花机排出的棉籽上剥取短绒之用，调整好不同的配车规格，分别可以剥取头道、二道或三道短绒。而且 MR141型剥绒机在原机的基础上作了重大改进。MR141 毛刷式锯齿剥绒机主要由六个部分组成，分别是机架部，工作箱部，锯筒部，毛刷部，喂籽箱部，自动喂籽机构部。由于本文作者研究课题的原因，本文侧重于总体结构和锯筒与工作箱的设计，部装结构则主要是对机器的结构分析及主要受力部件的强度校核。工作箱部是喂籽的主要部分，锯筒部是剥绒工作的主要部分。

Abstract
This text introduce MR141 brush type sawtooth shell overall design, saw a tube of departments and work case departments design of fine hair machine mainly. Model MR141 brush type sawtooth shell the fine hair machine in order to shell and fetch the using of short fine hair from cottonseed that the cotton gin discharges specially, Adjust mixing car specification different well , differentiate and can shell and fetch the first dish, two or three short fine hair. And MR141 type shell fine hair machine make great to improve on the basis of original machine. MR141 brush type sawtooth shell fine hair machine made up of six parts mainly, framework department separately, The case department of the job, saw one tube of departments, the brush department, Feed to the case department of seeds, feed to the mechanism department of seeds automatically. Because of the reason of the subject for research of the author of this text, this text lays particular emphasis on the ensemble architecture and design which saws tube and job case, Department install structure analyse and check strength intensity of part mainly structure in machine mainly. Job case department main part to feed seed, saw tubes of department to shell main part that fine hair work. [来源：http://think58.com]

引言
新中国成立以来，随着棉花生产的发展，我国棉花工业主要经历了两次飞跃性的发展。第一次是“5571”型锯齿轧花机取代皮辊轧花机，奠定了我国棉花加工业向工业化发展的基础。新中国成立前，籽棉加工是分散的、作坊式的民间轧花，使用的加工设备主要是人力或畜力皮辊轧花机。新中国成立后，随着纺织工业的发展，棉花生产大幅度地提高，棉花加工业随着棉花统购政策的实行而迅速地发展起来。首先用动力皮辊轧花机取代了人力或畜力皮辊轧花机，生产效率提高了10倍。1955年7月1日，我国成功试制了第一台锯齿轧花机——“5571”型。“5571”型锯齿轧花机的诞生结束了我国棉花加工业依赖皮辊轧花机和进口锯齿轧花机的历史，它的批量生产和应用标志了我国棉花加工业进入了工业化的时代。 [资料来源：http://www.THINK58.com]
第二次是“121”棉花加工新工艺和成套设备的研制成功并推广应用，缩短了我国棉花加工技术与国际先
