[0047] When the abrasive is discharged into the trough body 2011 through the screw conveyor 4, and is discharged downward through several discharge holes in the trough body 2011, and falls on the mold base containing the binder in the loading platform assembly 5, the three sweeping plates 2024 are driven by the sweeping motor 2021 to sweep the inner wall of the trough body 2011, so that the abrasive on the inner wall of the trough body 2011 can be evenly arranged, thereby ensuring that abrasive continues to fall in each discharge hole, and cooperate with the detection assembly 3 to detect the thickness of the bonded mold: select a suitable position according to the needs, plug the movable card plate 301 on the positioning card plate 302, so that the outer wall of the detection roller 304 just fits the mold with the abrasive, so that the pressure sensor in the detection roller 304 can sense a smaller pressure data. When too much abrasive is added to the mold, the mold becomes thicker, and the pressure sensor detection data becomes larger.
