[0024] The working principle of the present invention is as follows: Start the feeding motor 40, and move the mud supporting trough plates 42 carrying mud sticks to the top one by one. Then, the rodless cylinder 44 pushes the mud sticks in the uppermost mud supporting trough plate 42 into the mud inlet of the combined cylinder body 35 through the push plate. Under the conveyance of the spiral conveying shaft 37, the mud material that has been vacuumed by the vacuum box 3501 is extruded from the mud outlet of the combined cylinder body 35. The linear pusher 48 moves the positioning probe 49 to the corresponding position according to the mold type identified by the mold sensor. When the positioning probe 49 senses the head of the extruded mud strip, the reduction motor 36 stops extruding, and the mud throwing cylinder 50 pushes out the vacuum suction cup 51 to absorb the mud strip. Then, the mud cutting cylinder 47 pushes down the blade to cut the mud strip. The steering cylinder 52 pushes the mud throwing cylinder 50 to a vertical position. The vacuum suction cup 51 throws the mud strip into the lower mold 8 under the push of the mud throwing cylinder 50.

[0025] The mold 8 carrying the mud strips continues to move forward along the circulation line.

After the roller head 2 is clamped, the roller head seat 4 and the moving plate 10 are reset successively, and the adjustment motor 33 adjusts the angle of the roller head seat 4 through the push-pull rod 30. When the mold 8 moves to the top surface of the mold support 17, the circulation line is paused, the electric lifting plate 14 is started to lift the mold 8 so that it corresponds to the roller head 2, the rotary mold motor 16 and the drive motor 22 are started to drive the mold 8 and the roller head 2 to rotate respectively, and the mud strips in the mold 8 are rolled and formed, and the two linear modules are started to adjust the cutting knife 71 to a suitable position to cut off the excess mud generated during the rolling process. The carrier plate 62 can be fixed with an air blowing pipe to blow the excess mud into the waste conveyor belt 21 and take it out of the production line.

[0026] After the rolling operation is completed, each component is reset, and the mold 8 carries the formed green body and continues to move forward to the drying room 7 for drying. The dried green body flows out from the outlet of the drying room 7, and the vertical electric rail 57 drives the vertical suction cup 59 to move downward to absorb the green body and then reset, and then the transfer motor 55 is started to move the transfer seat 56 to the top of the transfer belt 54, and the vertical suction cup 59 moves downward again to release the green body, and the green body enters the next process with the transfer belt 54. The circulation line in the present invention is equipped with different types of molds 8, and the feeding mechanism, tool changing platform and adaptive roller head seat 4 distributed around the production line cooperate with each other.
