A displacement detection element for detecting the displacement of the detection disc 51 is arranged on the lifting cylinder. After the crucible 49 moves to the lower side of the detection disc 51, the lifting cylinder drives the detection disc 51 to descend. The detection disc 51 enters the crucible 49. If there is excess material in the crucible 49, the excess material will block the descent of the detection disc 51, so that the detection disc 51 slides along the lifting cylinder. Then, the displacement detection element detects the movement of the detection disc 51. If there is no excess material in the crucible 49, the detection disc 51 descends to the bottom of the crucible 49 along with the output end of the lifting cylinder.
