      Objective To design a food mechanical automatic quantitative filling system. Methods The programmable logic controller (PLC) was used as the core to design the control system and the fuzzy proportional integral derivative (PID) control algorithm was used to improve the accuracy and stability of the filling control system. Results In the 400 g weight section, the filling weight was (400.35±4.692) g, and the filling time average was (4.97±0.170) s; in the 800 g weight section, the filling weight averages (800.47±7.098) g, and the filling time average was (5.92±0.123) s; In the 900 g weight section, the average weight of the filling (899.98±8.870) g, and the average filling time was (6.43±0.080) s. The filling mass change rate was less than 2%, and the filling time was less than 7 s. Conclusion The design has high food filling accuracy and high mechanical stability and safety, which has great reference value for existing food packaging machinery devices and great promotion value.
