摘 要

洗瓶设备主要用于制药、化工、食品等行业灌装前的瓶子清洗.机构装置，洗瓶机的推瓶机构的功能利用推头平稳的将瓶子送进的一个过程，在急回到原点，反复运动。推瓶机构原理是利用铰链四杆机构和凸轮组合成一个洗瓶机推瓶机构，通过凸轮和铰链四杆机构本身特性来完成平稳送瓶和机构急回。经过多个方案对比分析，确定比较合适方案为凸轮铰链四杆机构，对其进行了参数设计。本设计对推瓶机构传动系统进行了设计和选择：首先，对洗瓶机推瓶机构的电机、减速器等主要的传动系统进行了设计选择，同时对推瓶机构的凸轮—铰链四杆机构进行了具体参数化设计，使的它的运动状态和运动规律能更好的实现其实际的工作。 最后通过对凸轮的轮廓曲线的调整和对铰链四杆机构杆长的局部修改，使推瓶机构的运动状态、工作行程等更加平稳流畅。

Abstract

Bottle washing equipment is mainly used in pharmaceutical, chemical and food industries cleaning before filling. Function push the bottle body mechanism means the use of a washing machine will be a smooth process Tuitou bottle fed, in acute back origin, repeated movement. Push bottle principle mechanism is the use of four-bar linkage hinge and cam be combined into a washing machine to push the bottle body and the hinge cam four-bar mechanism itself features to complete a smooth deliver quick return bottles and institutions. After comparative analysis of a number of options to determine the appropriate solution for cam four hinge mechanism, its design parameters. The design of the bottle body push drive system design and selection: First, the main transmission mechanism push the bottle washing machine motor, reducer made design choices, while pushing the bottle body cam - hinged four-bar mechanism conducted a detailed parametric design, make it the law of the state of motion and movement can better achieve their actual work. Finally, by adjusting the cam profile curve and the four-bar linkage hinge rod length of partial changes push the bottle so that the motion state agencies, such as the working stroke is more stable and smooth. Keywords: washing machine, push the bottle body, cam mechanism, four hinge mechanism
