Similarly, the first joint arm 124 can also drive the clamping mechanism 132 to reciprocate between the sand floating region 111 and the lower rack 170. In more detail, as shown in FIG. 7, the clamping mechanism 132 can first remove the shell mold to be smeared from the loading rack 160 and automatically send it to the slurry holding tank 101 for the sizing operation. As described above, the clamping mechanism 132 is rotatable relative to the first joint arm 124 to evenly smear. In some embodiments, after the clamping mechanism 132 leaves the slurry receiving groove 101, the shell clamping of the clamping mechanism 132 can also be performed by the blowing pipe 102. The gas is used to quickly transfer excess slurry back into the slurry receiving tank 101, thereby improving work efficiency and avoiding slurry waste. Next, the clamping mechanism 132 can be moved to the sand floating area 111 for sand wrapping operations. Finally, the clamping mechanism 132 is mounted to the lower rack 170 in an automatic pulp mold. At least the manual dampening and sand-wrapping operations are saved in the whole process. In addition, the staff only needs to replenish the shell mold after the shell mold of the loading rack 160 is removed, or the empty rack can be emptied after the lower rack 170 is covered with the shell mold. Therefore, the present embodiment can save manpower to the utmost extent, and the embodiment of the present invention can save at least 2 to 3 human forces compared to the conventional manual sizing and sanding operations.
