The utility model discloses a stirring device for flux production. Box body, the left side of the box body is fixedly connected with a first motor through a supporting plate. The top of an output shaft of the first motor is fixedly connected with a first belt wheel; the surface of the first belt wheel is in transmission connection with a second belt wheel through a belt, the axis of the second belt wheel is fixedly connected with a rolling shaft, and the bottom of the rolling shaft penetrates through the top of the box body and extends into the box body. According to the stirring device for production of the soldering flux, stirring is more uniform and thorough during production and processing of the soldering flux; and meanwhile, the double-layer stirring structure can accelerate the production and stirring efficiency of the welding-aid solvent, guarantee that the welding-aid solvent meets the later use requirement, reduce noise generated by mechanical collision when the stirring device works and purify the working environment, and therefore it is guaranteed that workers have a good working state and working efficiency.
