This invention discloses an automatic pottery throwing device for preventing cracking of low-temperature celadon clay, relating to the field of pottery throwing equipment technology. This automatic pottery throwing device for preventing cracking of low-temperature celadon clay achieves this by tilting the outer edge of the potter's wheel upwards. During the throwing process, when the clay and water flow to the top of the potter's wheel, the rotation of the wheel causes the clay and water to move outwards. Near the inclined conical surface of the potter's wheel, the clay and water are filtered through a perforated ring. This perforated ring blocks any clay clumps mixed in with the clay, and the centrifugal force during the rotation of the clay further propels the clay outwards, away from the perforated ring. Simultaneously, the perforated ring installed at the conical surface of the potter's wheel, which is adapted to the potter's wheel, also filters the clay at the conical surface. During rotation, any clay adhering to the holes is thrown out, ensuring the holes remain open and preventing the clay and water from accumulating and causing the bottom of the clay to be submerged in the clay, thus preventing collapse of the clay bottom during the throwing process.
