洗瓶机课程设计30574前言创新课程设计能够提高我们机械类专业学生的创新能力,也是我们综合应用所学的机械方面专业知识和技能解决问题,获得工程技术训练必不可少的实践性教学环节。本次创新课程设计所选的题目是洗瓶机设计。洗瓶是食品行业包装工艺流程中不可缺少的一环,设计出合理、高效的洗瓶机是包装技术发展的必然要求。洗瓶机的种类很多,目前国内市场上的洗瓶机有扭道式、箱式、滚筒式和立式等多种,其中以滚筒式洗瓶机和立式洗瓶机的应用最为广泛,且立式洗瓶机后来居上,发展势头迅猛,已取代了滚筒式洗瓶机的传统地位,目前国内生产立式洗瓶机的代表厂家有长沙楚天、上海远东、上海旭发、长沙正中等。在洗瓶机的设计中,结构紧凑、清洗效果与除标效果成为人们最为关注的要点。洗瓶机是的常见机械,按照清洗的功能和能力有各式各样的种类。一个完整的洗瓶机包含送料系统、清洗系统以及后续的加工包装系统。此次设计的洗瓶机,限于我们目前的知识水平和设计经验,我们仅仅是综合考虑了一些关键因素及设计要求,应用所学的机械专业知识,初步的设计了简单的洗瓶机的主要机构。目的是通过设计洗瓶机这一选题,进一步巩固所学的机械专业理论知识,将理论与实践相结合,作为一种初步的实践性探索。由于我们的设计经验尚不够丰富,错误及不足之处在所难免,敬请老师批评指正。目录第一章设计任务···········································31设计题目···········································32洗瓶机的技术要求··································33设计任务···········································44原始数据···········································4第二章机械运动方案设计·································51分析设计要求·······································52推瓶机构方案选择···································5方案一凸轮-铰链四杆机构······················6方案二多个曲柄滑块机构························7方案三五连杆机构······························8方案四曲柄滑块机构·····························9第三章推瓶机构的尺寸设计·······························10第四章传动系统的设计···································121传动过程分析·······································12转刷机构传动过程·······························12推瓶机构传动过程·······························13导辊机构传动过程·······························132传动比的分配·······································13第五章洗瓶机工作循环图·································16第六章洗瓶机总体设计及其布局··························17第七章其他机构的设计计算······························181转刷传动机构设计··································182内部清洗装置的设计·······························19第八章心得体会···········································21参考文献···················································22第一章设计任务书1、设计题目 洗瓶机主要是由推瓶机构、导辊机构、转刷机构组成。待洗的瓶子放在两个同向转动的导辊上,导辊带动瓶子旋转。当推头M把瓶子推向前进时,转动着的刷子就把瓶子外面洗净。当前一个瓶子将洗刷完毕时,后一个待洗的瓶子已送入导辊待推。如图1所示。图12、洗瓶机的技术要求表1洗瓶机的技术要求方案号瓶子尺寸(长×直径)mm,mm工作行程mm生产率个/min急回系数k电动机转速r/minAφ100×2006003314403、设计任务(1).洗瓶机应包括齿轮、平面连杆机构等常用机构或组合机构。学生应该提出两种以上的设计方案并经分析比较后选定一种进行设计。(2).设计传动
