Zusammenfassung:	The utility model discloses a novel feeding mechanism for polyester polyol production, which comprises a fixed plate, the top of the fixed plate is provided with a feeding pipe through a mounting frame and bolts, one side of the top of the feeding pipe is provided with a feeding pipe, the top of the feeding pipe is provided with an air pump, and the air outlet end of one side of the air pump is connected with a three-way pipe through a pipeline; the air outlet end of the bottom of the three-way pipe is connected with the feeding pipe through a pipeline, an air bag is connected into the feeding pipe through a reserved groove in a gluing mode, and the air outlet end of one side of the three-way pipe is connected with the air bag through a pipeline. According to the novel feeding mechanism for polyester polyol production, the air pump can inflate the air bag and the feeding pipe respectively, the air bag can bulge after being inflated so as to block the feeding pipe, and after the feeding pipe is inflated, mater
