Objective To study the kinematics of the executive link of feeding mechanism for candy packaging machine under theoretical conditions. Methods The dynamic characteristics of the linkage and cam mechanism were analyzed based on their mathematical models. The kinematic curves of the feeding mechanism were obtained with Matlab. Trajectory of this mechanism was simulated by establishing the model of the feeding mechanism using SolidWorks software. Results The kinematic formula for linkage was derived, the theoretical trajectory of the feeding mechanism was obtained, and the movement of the feeding mechanism was simulated. Conclusion The correctness of these mathematical models was shown by theoretical analysis and simulation results, which provided an important theory for the design and improvement of the feeding mechanism. This mechanism could ensure the kinematic trajectory in a reliable, accurate and stable way.
