The work aims to design a new feeding mechanism for candy packaging machine to better meet the technological requirements of candy packaging. The working trajectory of feeding mechanism of candy packaging machine was realized by Fourier non-circular gear train, and the mathematical model of Fourier non-circular gear train was established. According to the specific technological requirements on feeding of candy packaging machine, the auxiliary program of mechanism design was compiled by Matlab language, and the mechanism parameters that meet the requirements were selected through the program. Through the example calculation, it can be seen that the Fourier non-circular gear train can realize the working trajectory, and has a straight feeding travel length of 136.8 mm. The push rod can exit rapidly at the left most of the travel.The Fourier non-circular gear train can well realize the working trajectory of feeding mechanism and fulfill the technological requirements of candy packaging.
