基于CAD技术的小型上下胶带封箱机设计 DESING OF SMALL UPPER AND LOWER ADHESIVE TAPE SEALING MACHINE BASED ON CAD TECHNOLOGY 摘要 随着当今社会上各式各样产品的出现，对包装技术和包装设备也有了新的要求，封箱机在物流领域中发挥了越来越重要的作用。故在对封箱机进行了调查和研究后，本详细阐述了对封箱机的设计。 本以CAD技术为主，SOLIDWORKS为辅对胶带封箱机进行了研究，主要设计如下： （1）查看市面上现有的封箱机，利用SOLIDWORKS软件绘制封箱机三维图。 （2）查阅资料，分析封箱机的主要结构，制定总体设计方案。 （3）确定对传动结构、封箱结构和调节结构的设计方案。 （4）为保证设计出的封箱机能进行装配和运行，要对主要零件进行计算及校核。 （5）利用CAD技术，绘制出封箱机的装配图并进行检查。 关键词：封箱机；四杆机构；CAD技术；滚筒 Abstract With the emerge
