摘要 纸箱捆扎机是用捆扎带捆扎纸箱，完成捆扎作业的机器。工作时使用捆扎带缠绕纸箱，然后收紧并将两端通过热效应熔融或使用包扣等材料连接。本设计的纸箱自动捆扎机捆扎部分，由送带、退带张紧机构，捆扎封接机构、压带机构、捆扎带导向机构组成。 本文首先，通过对纸箱自动捆扎机现状进行全方位调研，在此基础上提出了捆扎部分方案；然后，设计并校核了各主要构成件的结构及强度；最后，通过AutoCAD制图软件绘制了机械手装配图、主要零件图并采用Pro/E软件进行三维设计及运动仿真。 通过本次设计，巩固了大学所学专业知识，如：机械原理、机械设计、材料力学、公差与互换性理论、机械制图等；掌握了机械产品的设计方法并能够熟练使用AutoCAD制图及Pro/E软件进行三维设计软件，对今后的工作于生活具有极大意义。 关键字：纸箱，捆扎机，设计，仿真 Abstract The carto
