7、原始数据（1)、瓶子尺寸:长度L=100mm,直径D＝2０0ｍm。(2）、推进距离Ｓ=６00mｍ，推瓶机构应使推移接近均匀得速度推瓶,平稳地接触与脱离瓶子,然后推头快速返回原位,准备进入第二个工作循环.（3）、按生产率每分钟3个得要求,推程得平均速度v=45mm/ｓ,返回时得平均速度为工作时得平均速度得三倍。(4)、电动机转速为1440r/min。(５)、急回系数3。二、机械运动方案设计２、１分析设计要求由题目可知：洗瓶机主要由推瓶机构、导辊机构、转刷机构组成。设计得推瓶机构应使推头M以接近均匀得速度推瓶,平稳地接触与脱离瓶子,然后,推头快速返回原位,

8、准备第二个工作循环。根据设计要求，推头Ｍ可走图1所示轨迹，而且推头Ｍ在工作行程中应作匀速直线运
