英文摘要：

The control on automatic feeding device by using PLC soft was studied, including its overall scheme design, the design and model of the mechanical structure, design for hydraulic drive system, PLC control, programming and so on. The program logic debugging and verification of the corresponding were carried out. The results show the correctness and effectiveness of the program, which can provide a reference for the design and control of complex feeding mechanism.
