Intelligent oil-saving internal mixer lubricating system

The invention discloses an intelligent oil-saving internal mixer lubricating system, and belongs to the technical field of lubricating systems. The internal mixer lubricating system comprises four sets of relatively independent oil drum devices, a material level detector, a variable frequency motor device, an automatic oil filling valve, a temperature measuring element and an electric control device. Detecting the temperature of the machine body sealing ring through the temperature measuring element; the electric control device automatically adjusts the rotating speed of the variable frequency motor device according to the temperature of the sealing ring so as to adjust the lubricating oil output; the material level detector can detect the lubricating oil level in the oil drum device and transmit a material level signal to the electric control device to be displayed. The electric control device controls the automatic oil filling valve to automatically fill oil according to the lubricating oil amount in the oi
