[0002] Ceramics are various products made from natural clay and various natural minerals through crushing, mixing, molding and calcining. Ceramics is a general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products made from inorganic non-metallic minerals such as clay as raw materials. It includes various products made from clay or mixtures containing clay through mixing, molding and calcining, ranging from the roughest earthenware to the finest fine pottery and porcelain.

[0003] In the prior art, roll forming is a method for forming a ceramic body, which uses a structure with a rotating body instead of a mold cutter as a main forming component, and processes the ceramic body to achieve the forming purpose.

[0004] Currently, the existing ceramic green body rolling machines have a relatively complex structure. Most of them rely on motors to transmit power to the mold base shaft through a V-belt or motors to drive a large cam to provide power for the rolling head, which causes great damage to the motor, resulting in a high equipment failure rate and great difficulty in maintenance.
