The electromagnet 39 is activated, the clamp 38 is loosened, and the raw material 13 to be disassembled falls into the raw material forming module 4. Subsequently, the feeding mechanical arm 28 starts to draw the wet material and the dry material from the wet material tank 8 and the dry material tank 9 respectively through the pipe 10 and spray them onto the raw material 13 to be de-threaded. The brush mechanical arm 29 controls the brush so that the wet material and the dry material are more evenly spread on the raw material 13 to be stripped. Finally, the platen mechanical arm 26 controls the platen 27 to press so that the raw material 13, the wet material and the dry material are mixed more fully.

After the raw material 13, wet material and dry material of the first layer are fully mixed, the upper center push rod 34 on the outer lifting platform 35 shrinks to drive the inner lifting platform 33 down, so that the raw material forming module receiving plate 32 is on the column 31 Swipe down in the middle.
