The study aimed to design an automatic production equipment and its control system which included bag making, filling and sealing. S7-1200PLC was used as the control system of the packaging machine. The touch screen was used to adjust sealing temperature and online display. The feeding device was set using compressed gas of air blowing type to realize high-speed feeding. The execution of each action was controlled through reading the rotary encoder angle by high-speed counting of PLC and the sealing temperature was controlled by PID, thus, the steady control effect was realized. With the use of PLC and touch screen, the flexibility of the system was increased and the high speed packaging was achieved.
