In this way, it is convenient for the belt transmission component 21 to continuously output the material plate 51 at the bottom of the storage cavity 101 from the discharge port 102. By adjusting the screw 133, the distance between the stop arm 132 and the belt transmission component 21 can be adjusted to control the discharge port 102 to match the thickness of one layer of the material plate 51, so as to output the material plates 51 in the bin 10 layer by layer.

Since the first side plate 11, the second side plate 12 and the connecting seat 131 all slide along the sliding rod 141 (such as Figure 1 the Y-axis direction in), it is convenient to position the edge position of the material plate 51.
