以机械机构的参数化设计为启示，论述了全自动纸杯成型机卷封机构的工作原理，分析了卷封凸轮机构的运动规律。在此基础上，提出了利用ADAMS的参数化功能，对纸杯机卷封凸轮机构进行了参数化设计，以达到设计过程简单化，同时也对基于ADAMS的纸杯机卷封凸轮机构进行了运动仿真。

The operating principle of seaming mechanism of automatic paper cup machine was introduced and the motion law of the cam mechanism was analyzed. The application of ADAMS parametric function was put forward to carry out parametric design of seaming mechanism of automatic paper cup machine. This method simplified the design process. The simulation three-dimension movement of operation seaming cam mechanism was introduced.
