The plurality of storage boxes 30 separately store a plurality of types of raw materials. The storage box 30 is communicated with the corresponding feeding box 13, the top of the mixing tank 10 is provided with a mounting frame 40, the mounting frame 40 is horizontally and slidably provided with a sliding plate 50, and the driving assembly 60 is arranged on the mounting frame 40 for driving the sliding plate 50 to slide. The bottom of the discharging box 24 and the sliding plate 50 are connected with a bellows 51. When the staff needs to add raw materials into each feeding tank 11, the sliding plate 50 is first driven to slide by the driving assembly 60, so that the lower end of the bellows 51 is located above one of the storage boxes 30. Then the staff pours the raw materials into the hopper 25, and the raw materials are sent to the discharging box 24 by the partition synchronous belt 21, and then fall into the storage box 30 through the bellows 51, which is convenient for operation.
