Abstract: To provide a theoretical basis for optimizing its performance, the kinematic characteristics of foil-wrapped cigarettes pusher device in the new type ultrahigh-speed packer were studied. Based on the analytical model of the pusher, the movement trajectory of its working point was calculated by analyzing its working principle. By referring to the dynamics theory of multiple-rigid body, a simulation model was established for determining the movement trajectory of its working point. The trajectory obtained by the analytical model was compared with that by the simulation model, the two agreed pretty well, it confirmed the correctness of the dynamics simulation model. The key kinematic characteristics, including displacement, velocity and acceleration of the pusher were analyzed with the simulation model. Theacceleration of long-arm pusher was tested and compared with the results of simulation calculation. It was proved that the pusher device could accurately moved along the preset trajectory and gently push foil-wrapped cigarettes into the reciprocating mandrel at the speed of1 000 packet/min.
