基于压板升降握持梳理的绢纺圆梳机构设计 摘要 传统的绢纺工程的工艺流程，自动化程度低，工艺流程较长，劳动强度大，经济效益很低。团队设计了全自动流水线绢纺，整个流程需要副夹板进行取绵和输绵，由于全程都要用到副夹板，一旦发生了问题，整个流水线都要瘫痪，基于压板的圆梳机构由此而生。本文设计了基于压板的圆梳机构，对原有结构进行改进优化。 本文主导针对基于压板的圆梳机构的改进如下: 1.考虑到梳绵是用传送带和压板机构同时进行输送的，原始的送棉机构停止运作并进行梳绵运动时，绵条是禁止不动的，此时梳绵，会产生梳绵不均匀，不细密等问题，因此，改进了送棉机构以及压板机构。 2.考虑到梳绵时梳理滚筒的连贯性，使用一个梳理滚筒进行工作，另一个梳理滚筒待用的形式，当一个梳理滚筒饱和时，利用梳理滚筒移动机构进行运动，设计出能用于梳理滚筒往复直线的机构或者元件。 3.考虑到输入罗拉和输出罗拉需要动力，利用链条与双联齿轮的配合，将动力输送，两罗拉之间使用齿轮啮合。 关键词：梳绵；自动化；全自动圆梳机；机械结构； SolidWorks；Adams Desig
