The two stopper discs 12b in each stopper disc 12b group rotate synchronously, and the stopper discs 12b groups on the same side of the rotation shaft can rotate synchronously. In the initial stage of the working process, the stopper part 121 of the uppermost stopper disc 12b extends into the projection range of the opening of the storage cylinder 11, so that the edge of the cover 5 can be arranged on the stopper part 121, then the stopper disc 12b group on one side of the rotation shaft rotates by a predetermined angle, so that the stopper part 121 of the stopper disc 12b close to the storage cylinder 11 rotates out of the opening projection of the storage cylinder 11, so that one side of the cover 5 can pass through the falling gap 122, and the stopper part 121 of the stopper disc 12b away from the storage cylinder 11 moves into the opening projection of the storage cylinder 11, so that the cover 5 can be arranged on the stopper part 121 of the lower stopper disc 12b after passing through the falling gap 122 of the upper stopper disc 12b, so that the lowermost stopper disc 12b is inclined, and at this time, since the diameter of the storage cylinder 11 is the same as the diameter of the cover 5, and the upper edge of the lowermost cover 5 supports the upper cover 5 after the inclination of the lowermost cover 5, the gap between the two or three covers 5 close to the lowermost cover 5 at the low point position of the lowermost cover 5 increases, at this time, the turnover and grabbing unit 2 is controlled to be arranged on the upper suction disc 222, which can suck the inclined cover 5 at the lowermost position, then the stopper disc 12b group on the same side continues to rotate by a predetermined angle, the stopper part 121 of the stopper disc 12b close to the storage cylinder 11 can be inserted between the two covers 5 at the lowermost position, so that the cover 5 at the lowermost position falls downward, the cover 5 at the upper position is guided upward by the chamfer of the edge of the stopper part 121, and is arranged on the stopper part 121; and the cover 5 at the lowermost position is separated from the stopper disc 12b on the other side with the rotation of the turnover frame 23, the other grabbing unit 22 rotates to the lower side of the storage cylinder 11 from the other side, the stopper disc 12b group on the other side rotates by a predetermined angle, and the above steps are repeated, so that the cover 5 at the lowermost position can be separated from the storage cylinder 11 from the other side at this time, and the cover 5 falls downward alternately from both sides of the storage cylinder 11 to the upper side of the milk powder tank 4.

[0044] Those skilled in the art should know that the material blocking disc 12b group can be respectively controlled to rotate by two or more groups of stepping motors, which will not be repeated here. The suction disc 222 can be selected with a suction disc 222 with a pleated part to adapt to the inclination angle of the cover 5 when sucking the cover 5.
