The disc workbench 1 continues to rotate a fixed station of the plaster mold 7, and the six-shaft mechanical arm 3 finishes the next transfer of the plaster mold 7 containing the wet blank 701 on the disc workbench 1 to the first layer drying disc 8 until all the plaster molds are exchanged. After the first-tier drying trays 8 are exchanged to complete the plaster molds 7 of the wet blanks 701, the six-axis robot 3 starts to exchange the plaster molds 7 of the wet blanks 701 to the second-tier drying trays 8, and the operation is circulated until the drying trays 8 of the respective tiers are exchanged to complete the plaster molds 7 of the wet blanks 701. After the drying disc 8 is used for placing the gypsum mold 7 containing the wet blank 701, because the drying disc 8 is filled with hot gas, on one hand, the drying disc 8 heats the bottom of the gypsum mold 7 containing the wet blank 701, on the other hand, the hot gas is blown to the gypsum mold 7 containing the wet blank 701 on the lower-layer drying disc 8 from the hot air port 804 at the bottom of the drying disc 8, so that the gypsum mold 7 is heated up and down simultaneously, the wet blank 701 is dried more quickly, the heat efficiency is higher, and the energy is saved more. After the wet blank 701 in the outer casing 6 is dried to become a dry blank 702, the dry blank 702 in the outer casing 6 is transferred to the disc worktable 1 by the six-axis manipulator 3, and the working process is as follows: the second clamping jaw 302 of the clamping jaw assembly of the six-axis manipulator 3 clamps a gypsum mold 7 containing a wet blank 701 on the disc worktable 1 and moves upwards and rotates 180 degrees to the horizontal position of the first layer of drying disc 8, the first clamping jaw 301 clamps the gypsum mold 7 containing the dry blank 702 on the drying disc 8 from the gypsum mold exchange port 601 of the shell 6, the clamping jaw assembly rotates 180 degrees again, the second clamping jaw 302 sends the gypsum mold 7 containing the wet blank 701 to the placing station just vacated by the drying disc 8, the bottom of the gypsum mold 7 is sleeved on the positioning boss 801 to prevent rotation and throwing displacement, then the first clamping jaw 301 of the six-axis manipulator 3 clamps the gypsum mold 7 containing the dry blank 702 and moves downwards to the disc worktable 1 to place the gypsum mold 7 containing the dry blank 702 in the fixing station vacated by the disc worktable 1, and the disc worktable 1 continues to rotate a fixing station of the gypsum mold 7 to circularly exchange the gypsum mold 7. When the gypsum mold 7 containing the dry blank 702 rotates to the position below the blank taking mechanical arm 4 along with the disc workbench 1, the blank taking mechanical arm 4 takes out the dry blank 702 in the gypsum mold 7. After the dry blank 702 is taken out, the empty gypsum mold 7 rotates to the automatic mud feeder 5 along with the disc workbench 1 to receive the porcelain clay lumps 9. The six-axis robot 3 successively exchanges the plaster molds 7 containing the dry blanks 702 on the first-layer drying tray 8 with the plaster molds 7 containing the wet blanks 701 on the disc table 1. And then sequentially exchanging the gypsum molds 7 containing the dry blanks 702 of the drying disks 8 of each layer with the gypsum molds 7 containing the wet blanks 701 on the disc worktable 1 upwards to finish an exchange period, and then performing the cycle of the next period.
