TRIPLE-DRUM TIRE-FORMING MACHINE AND MATERIAL-CONVEYING METHOD THEREFORE

The invention discloses a triple-drum forming machine for a tire, and a material conveying method of the triple-drum forming machine. An overhead portal frame structure is adopted in the preparation and conveying processes of a tire body component and a belted layer-tread component, namely a tire body transfer ring component and a belted layer transfer ring are conveyed in a sliding manner along a portal frame at the top to finish an air operation of all materials, so as to clear related ground conveyers, control and auxiliary operations of an operator in a tire manufacturing process are facilitated, and a collision accident is avoided. The triple-drum forming machine for the tire comprises a tire body drum, a belted layer drum and a forming drum, which are arranged on the same horizontal axis, wherein a portal frame for conveying a raw material is vertically arranged above the tire body drum, the belted layer drum and the forming drum; the transverse central line of the portal frame overlaps with the axial center lines of the tire body drum, the belted layer drum and the forming drum; the tops of the tire body transfer ring component and the belted layer transfer ring are respectively connected to the portal frame in a sliding manner; the portal frame comprises a horizontally arranged truss and a plurality of groups of vertically arranged upright posts; the horizontally arranged truss is connected with the vertically arranged upright posts..
