The device comprises a feeding assembly, a mixing assembly is fixedly arranged at the bottom of the feeding assembly, and a filter hopper is fixedly arranged at the bottom of the mixing assembly; the six mixing assemblies are movably arranged on the connecting ring, each mixing assembly comprises a connecting rod, a sliding block, a stop block, a compression spring, a stirring rod, a torsion spring and a stirring blade, one end of each connecting rod is fixedly connected to the inner wall of the connecting ring, the other end of each connecting rod is fixedly connected to the bottom end of the outer wall of the transmission shaft, and the sliding blocks are movably connected to the connecting rods; one side surface, close to the transmission shaft, of the slide block is fixedly connected with a stop block, and the other side surface is fixedly connected with a stirring rod. By arranging the mixing assembly for adjusting the stirring force according to the output power of the motor, the output power of the motor can be changed according to the input amount of materials, the larger the input amount is, the larger the output power is, and otherwise, the smaller the input amount is, the smaller the output power is.
