摘要
回转式拧瓶盖机适用于带螺纹的盖与瓶的旋盖，市场上现有的回转式拧瓶盖机大多数是半自动的包装机，瓶盖的疏理大多由人工来完成，生产效率不是很高，而且加大了劳动的强度，再生产时有一定的危险，本设计为自动理盖而且是多工位拧盖机。
本文介绍了题目的研究背景和意义，论述了拧盖机在国内外的发展状况，介绍了本次设计研究的内容及方法。本次设计的重点是拧盖机的总体设计方案、过程的拧盖、输送方式和定位方法，在此基础上进行了运动与结构的设计。本次设计采用的拧盖方法是回转式的，是通过圆柱凸轮的轮廓线来实现拧盖头的上下往复运动的，通过锥齿轮传递转矩；而且在满足拧盖机原理的条件下，充分考虑了整机的布局和经济性，不但结构简单明了，操作方便而且本课题的设计实现了从进瓶到出瓶的全部自动化，具有速度可调、定位准确、旋盖可靠、运行平稳、无噪音和不伤瓶盖等优点，克服了传统机构的缺点，总体上达到了我们预期设计的目标。

Abstract
Rotary Capping Machine for the threaded cap and the bottle of screw cap, as the existing rotary capping machines are mostly semi-automatic packaging machine, bottle of Reorganizing the employer to complete most of the production efficiency is not very high and increased labor intensity, have a certain risk of reproduction, the design for the automatic management is a multi-position cap and screw cap.
    This article describes the background and significance of the research topics discussed. Capper development at home and abroad, introduces the design of this study the content and methods. The packaging machine is designed to focus the overall design scheme, the packaging process of screwing conveyance methods and positioning methods, in this based on the movement and structure design. The design of the packaging used is rotary,through cylindrical cam contour to achieve capping head up and down reciprocating motion through the planetary gear transmission torque; and packaging machinery to meet the conditions of principle, give full consideration to the machine layout and the economy, while machine is also simple, low cost, no pollution, noise and human and functional characteristics of reasonable.
