[0002] Ceramic tableware refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. Its production process and production process are relatively complicated and require multiple processing and firing steps.

[0003] In the prior art, the production process of ceramic tableware is mostly to grind and screen the clay to ensure the fineness and purity of the material, and then mix it with an appropriate amount of water to make the clay into a slurry with good plasticity. The slurry is then placed in a mixer for stirring to mix it evenly and remove the bubbles in it. Then, the porcelain slurry is poured into a mold for molding. After the molding is completed, the rare earth ceramic tableware needs to be placed in a drying equipment for baking to evaporate the water in the porcelain slurry to make the porcelain denser and stronger. After the drying is completed, the initial firing and quality inspection operations are carried out. After the tableware embryo is completed, the glaze needs to be coated on the surface of the embryo, and finally the bottom glaze is dried and solidified by the drying equipment.

Under the action of air pressure, the hot air in the drying area will flow along the upper surface of the ceramic tableware below the hot air outlet nozzle 31, through the gap between the side of the ceramic tableware and the drying bucket 11, along the air inlet hole, the air inlet pipe 14, the air supply pipe 15 and the drying pipe 10 into the material taking monitoring area, and the gas in the material taking monitoring area is discharged by starting the exhaust fan 33.

[0046] Method five, position-changing drying, the industrial hot air blower 28 and the exhaust fan 33 are started, and when the ceramic tableware is dried, the stepping power motor 6 can be started. When the stepping power motor 6 drives the drying loading component to change its position alternately, the movement of the drying loading component drives the adjustment gear 18 to move at the same time. When the adjustment gear 18 moves along the adjustment inner gear ring 17, the adjustment gear 18 rotates on its own. The rotation of the adjustment gear 18 drives the drying tube 10 connected thereto to rotate. With the cooperation of the toothed transmission belt group 19, the other drying tube 10 rotates synchronously. The position of the ceramic tableware can be rotated and changed by the rotation of the drying tube 10.

[0047] Method 6: Unloading. After the ceramic tableware in the baking oven 2 is dried, the sealing electric cylinder 23 is started to move the sealing plate 22 into the sealing box 21. The ceramic tableware is moved to the outside of the baking oven 2 by the alternating cooperation of the stepping power motor 6 and the feeding and taking electric cylinder 24 again, and the next batch of drying operations can be carried out.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
