The utility model discloses a feeding device for the production and manufacture of thermal insulation cotton, which specifically relates to the technical field of thermal insulation cotton production, including a box body, a storage box is fixedly installed on the top of the box body, a conveying structure is arranged inside the storage box, a feeding pipe is penetrated through the side wall of the box body, the bottom of the feeding pipe is connected to the bottom of the storage box through a connecting pipe, a No. 2 motor is fixedly connected to the bottom end of the feeding pipe, a supporting structure is arranged between the feeding pipe and the bottom wall of the box body, and a discharge pipe is connected to the top of the feeding pipe. The utility model has the function of automatically and evenly adding raw materials to the mixer during the mixing stage of the thermal insulation cotton, and the raw materials inside the storage box can be evenly fed into the feeding pipe through the conveying structure and the feeding pipe, and then enter the mixer through the discharge port to complete the feeding work, and the feeding pipe can be maintained stable during the feeding process by setting the supporting structure.

[0017] Compared with the related art, the feeding device for producing thermal insulation cotton provided by the present invention has the following beneficial effects:
