推烟包装机推手机构的设计、制造及安装等精度要求较高，且组成零件多，因此设计分析复杂、廓线求解烦琐，采用传统的方法很难对其进行准确的分析。采用机构分拆法对组合机构进行了拆分组件，然后利用复极矢量函数对其各组件建立数学模型，最终获得了烟包推手的运动学方程式，为进一步研究推烟包装机推手机构奠定理论基础。

The cigarette packaging machine pusher, which has a lot of parts, has high precision requirement in design, manufacture, and installation. It is difficult to analyze the pusher accurately with traditional method for its complex design and contour line. Mechanism splitting method was applied to split components and the mathematical models of bipolar vector function were established for the components. The kinematics equations of package pusher were obtained. The purpose was to provide theoretical basis for further research in cigarette packaging machine with pusher mechanism.
