as shown in fig. 2, when the carrier plate 12 carrying the empty mold 11 is transferred onto the upper roller belt 604 by the upper layer transfer line 10, the transfer mechanism 4 loads the empty mold 11 onto the mold loading station of the turntable 5, then the mold 11 rotates clockwise along with the turntable 5 to the loading station, the mud extruder 8 inputs mud into the opening of the mold 11, the loaded mold 11 continues to rotate to the rolling station, the lifting table 904 is lifted, the sleeve 906 is sleeved into the mold 11 and drives the mold 11 to rotate, the roller head rotating in the rolling device 909 is lowered into the mold 11 to roll the mud, after rolling forming, the mold 11 rotates to the mold unloading station, meanwhile, the roller belt 604 is lifted up along with the cam to transfer the carrier plate 12 onto the opposite side transfer line 10, then the transfer mechanism 4 clamps the mold 11 on the mold unloading station and unloads the mold 11 onto the carrier plate 12, and during the mold unloading, the transfer mechanism 4 simultaneously loads the next empty mold 11 onto the mold loading station (see fig. 15).

The die 11 after die unloading enters the drying room 1 along with the opposite side conveying line 10 to dry the blank for the first time, then the die 11 continues to be conveyed to the lifting mechanism 3, the roller table 303 in the lifting station on the side of the lifting mechanism 3 is positioned at the upper dead point position, at the moment, the rotation direction of the electric roller in the roller table 303 is consistent with that of the upper layer conveying line 10, the carrier plate 12 is conveyed onto the roller table 303, the roller table 303 is lowered to the lower dead point position, the electric roller is reversed, the carrier plate 12 enters the side lower layer conveying line 10, the conveying direction of the lower layer conveying line 10 is opposite to that of the upper layer (see figure 3), the carrier plate 12 carries the die 11 to enter the drying room 1 to dry for the second time, then the carrier plate 12 is conveyed onto the lower layer roller belt 604, the roller belt 604 is jacked up along with the cam, the carrier plate 12 is conveyed onto the opposite side roller belt 604, and the roller belt 604 is reset to the lower point, the carrier plate 12 enters the lower layer conveying line 10 on the opposite side, and enters the drying room 1 again along with the conveying line 10 to dry the blank for the third time, then the carrier plate 12 enters the upper layer conveying line 10 on the opposite side through the lifting mechanism 3, and is stopped below the clamping device 706 under the blocking of the built-in elastic arm steric hindrance of the conveying line 10, the deviation correcting manipulator 7 rotates and aligns the mould 11, so that the orientation of the inner mould assembling line can be matched with each device in the mould opening blank taking machine 2, two groups of corrected moulds 11 take out the inner moulds in the mould opening blank taking machine 2, blanks in the inner moulds are discharged onto the output belt 206 to be transmitted out of the production line, the inner moulds after blank taking are cleaned by the mould brushing device 207 and are then re-assembled into the outer mould, the empty mould 11 after discharging enters the drying room 1 along with the conveying line 10 for the fourth time, and the dried empty mould 11 returns to the upper layer roller belt 604 to be ready for the next circulation.

The production line can fully automatically produce various ceramic products by a roll forming method, adopts a double-layer parallel circulation structure, can pass through a once circulation four-time drying mold 11, improves the production efficiency while meeting intermittent drying, and has the characteristics of compact structure and small occupied area.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
