The work aims to use a six-bar mechanism in the packaging paper feeding device, simulate its kinematics and dynamics to verify whether it meets the actual working requirements in the process of movement and improve the production efficiency of packaging paper feeding device. The kinematics model and dynamics model of the six-bar mechanism were established with vector analysis method and separation method, and the kinematics and dynamics of the mechanism were simulated by Adams. Through the kinematic simulation analysis of the six-bar mechanism, the displacement, velocity and acceleration curves of the output slider 4 were obtained. The horizontal travel of the mechanism was 680.26 mm, which met the requirements of the actual working conditions. Through the dynamic simulation analysis of the six-bar mechanism, the force on each hinge joint of the six-bar mechanism and the balance torque applied to the crank 1 were obtained. In the paper feeding travel of the mechanism, the force and balance torque of each hinge joint changed slightly. While, the force and balance torque of each hinge joint changed greatly during the return travel of the mechanism after the paper feeding was completed. It is found in the analysis of the simulation results that the six-bar mechanism meets the actual working requirements in the movement process, and can be better applied to the packaging paper feeding device.
