Optionally, the first supporting cushion plate 41 is made of steel material, so that the first supporting cushion plate 41 can reliably support the first supporting cushion layer 42. Preferably, the first supporting cushion layer 42 is made of non-metallic material, so that the first supporting cushion layer 42 made of non-metallic material is used to isolate the first supporting cushion plate 41 from the conveyor belt 1, reduce the friction between the first supporting cushion plate 41 and the conveyor belt 1, and improve the service life of the equipment. Preferably, the second supporting cushion plate 43 is arranged between the supporting mechanism 4 and the second compaction roller 25, and the conveyor belt 1 is arranged above the second supporting cushion plate 43, so that the second supporting cushion plate 43 supports the area of the conveyor belt 1 between the supporting mechanism 4 and the second compaction roller 25, preventing the conveyor belt 1 from deforming in this area and causing uneven distribution of the powder on the conveyor belt 1, and ensuring that the thickness of the powder on the conveyor belt 1 remains uniform during the conveying process. Optionally, the second supporting cushion layer 44 is arranged between the conveyor belt 1 and the second supporting cushion plate 43. Optionally, the second supporting cushion plate 43 is made of steel material, so that the second supporting cushion plate 43 can reliably support the second supporting cushion layer 44. The second supporting cushion layer 44 is made of non-metallic material, so that the second supporting cushion layer 44 made of non-metallic material is used to isolate the second supporting cushion plate 43 from the conveyor belt 1, reduce the friction between the second supporting cushion plate 43 and the conveyor belt 1, and improve the service life of the equipment.Preferably, the powder with uniform thickness is conveyed by the conveying belt 1 into the compaction gap 22, and the powder is compacted by the compaction belt 21 and the conveying belt 1 to form a ceramic green body with uniform density. Further, the compaction gap 22 is provided with the side limiting strips 23 on both sides, which can constrain the powder during compaction to prevent the powder from overflowing and spreading to the outside of the compaction gap 22. Optionally, the first compaction roller 24 drives the compaction belt 21 to move closer to or away from the conveying belt 1 to adjust the size of the compaction gap 22. The second compaction roller 25 is supported below the conveying belt 1 and is arranged opposite to the first compaction roller 24 to reliably stabilize the conveying belt 1 at a predetermined height, and the compaction belt 21 is spaced apart to form a compaction gap 22 with a predetermined size, thereby ensuring that the compaction gap 22 can effectively compact the powder on the conveying belt 1 into a ceramic green body. Further, preferably, after the compaction gap 22 compacts the powder into a ceramic green body, the pressure maintaining cylinder 8 drives the first pressure plate 6 to pressurize the compaction belt 21, while the second pressure plate 7 is supported below the conveying belt 1 to drive the conveying belt 1 to continue to pressurize the ceramic green body together with the compaction belt 21, thereby preventing the ceramic green body from swelling when exhausting air and ensuring the dimensional stability of the ceramic green body.
