[0037] A method for producing a ceramic flower pot, wherein the ceramic flower pot is produced by the device for producing a ceramic flower pot, comprising the following steps: S1 feeding: the feeding device feeds the clay rods into the refining device, which stirs the clay rods to form clay material, and puts the clay rods into the material tray. When the material tray is lifted to the tray position by the lifting belt, the lifting belt stops lifting, and the pushing rod moves into the material tray to push the clay rods to the back of the tray and into the feeding port of the cylinder. When the clay rods are pushed out of the material tray, the pushing rod retracts and moves out of the material tray.

[0038] In S2, a predetermined amount of clay is fed into the mold on the conveyor. The mold rotates forward, and the molding device's spinning head extends into the mold cavity, spinning the clay into a flower pot blank. A cutter moves into the upper end of the mold to flatten the top of the flower pot blank. After the clay is fed into the mold cavity, the mold rotates forward, and the rotating arm rotates to move the spinning head into the mold cavity. The spinning head rotates backward, squeezing the clay against the inner wall of the mold cavity to form the flower pot blank. A trimming knife cuts off the clay that overflows from the upper end of the mold cavity, forming waste, which is then blown away by an air nozzle.

The first transport device places the shaped flowerpot blank on the conveyor device onto the first turntable. The flowerpot blank rotates with the first turntable. The nozzle sprays water on the grinding disc, rotating the grinding disc and bringing the grinding disc close to the top of the flowerpot blank to grind the top of the flowerpot blank. The flowerpot blank rotates with the first turntable. The second turntable is rotated so that the flowerpot approaches the calibration wheel of the calibration device. The calibration wheel pushes the flowerpot blank to move on the first turntable so that the center of the flowerpot blank is located on the rotation axis of the first turntable. The second turntable continues to rotate, and the flowerpot blank approaches the upper part of the inclined grinding pad. The first turntable drives the flowerpot blank to rotate, and the upper part of the grinding pad, which has been wetted by the nozzle, grinds the flowerpot blank. The muddy water produced by grinding adheres to the grinding pad. The squeezing wheel can squeeze the grinding pad, squeezing the muddy water out of the grinding pad. The muddy water flows out from the lower half of the grinding pad and does not drip onto the flowerpot blank, so that the outer surface of the flowerpot blank does not adhere to the muddy water.

[0040] The second turntable continues to rotate, driving the flower pot blank to leave the grinding device, and the second transporting device moves the flower pot blank away from the trimming device.

[0041] S5 post-processing, the flower pot blank with the trimmed ends is subjected to air drying, glazing, and firing steps in sequence to form a flower pot.
