Belted layer laminating drum

The utility model discloses a belted layer laminating drum, which belongs to the technical field of tire forming, and comprises a main shaft, a plurality of drum tiles arranged around the main shaft in the circumferential direction, a support piece, a pushing mechanism and an adjusting mechanism, the support piece is fixedly connected with the drum tiles, and the support piece can move in the radial direction relative to the main shaft; the pushing mechanism comprises a first part and a second part, and the second part can move in the axial direction of the main shaft relative to the first part to drive the supporting piece; the adjusting mechanism is in transmission connection with the first part and can drive the pushing mechanism to move in the axial direction of the main shaft. Throughthe arrangement of the adjusting mechanism, the relative position of the pushing mechanism in the axial direction of the main shaft can be adjusted, then the diameter of each drum tile at the expanding position can be set, a
