Abstract

The utility model relates to ceramics roller forming, in particular to a roller forming device and ceramics formed by the roller forming device among the ceramics roller forming. The roller forming device comprises a rolling head. The rolling head is provided with a pattern forming face. Mud blocking grooves are arranged at ends of edges of the pattern forming face. The mud blocking grooves are arranged in a rotary mode around an axis of the rolling head. The roller forming device and ceramics formed by the roller forming device has the advantages that in roller forming, the mud blocking grooves can increase resistance to edge portions of openings of the ceramics, and edge portions of the openings of the ceramics are more compact, so that deformation of the ceramics in firing is avoided.
