This application relates to a material level warning device for the storage cylinder of a blow molding machine, comprising a shell fixed on the inner wall of the cylinder. The shell is hollow and provided with a side connecting groove, inside which a rotating rod is hinged. One end of the rotating rod extends into the shell, and the outer end is hinged with a vertically arranged connecting rod. The lower end of the connecting rod is fixed with a detection block that descends with the material level, and the inner end is connected with an indicating assembly for material level display. When the material level drops to the low limit, the detection block moves downward to drive the rotating rod to rotate upward, triggering the indicating assembly to send a visible reminder for operators, realizing low material level early warning.
