Background

For the forming of all-steel small and medium-sized engineering radial tires, a one-step forming process is mostly adopted in the market at present, and an online extrusion winding process is mostly adopted for tread rubber materials, but the online extrusion winding time of the tread is longer and is basically the same as the tire forming rolling time. At present, a common latest once-through four-drum engineering radial tire building machine only carries out inflation shaping on one building drum, and only winds the other winding drum, a tire blank is subjected to inflation shaping rolling on the building drum, then is transferred to the winding drum from a new forming drum through transfer ring transfer, and then is wound on the winding drum after being subjected to secondary inflation shaping, and the secondary inflation shaping easily causes left-right asymmetry of the tire blank, especially for tires with specifications above the middle layer, and the secondary transfer shaping causes serious deformation of the tire blank and influences the quality of the tire.

At present, another rotary four-drum engineering tire forming machine comprises a tire body attaching drum, a belt ply drum and two forming drums, wherein the four drums are arranged in a row, the two forming drums can rotate for 180 degrees, the forming drum on the left side is used for forming a tire, and the forming drum on the right side is used for winding a tire tread of a tire blank. The equipment has the advantages that the occupied area is large, the equipment cost is high, the tire forming and tread extruding and winding production time sequence conflicts of the two forming drums are realized, the left forming drum can perform the positioning process of the tire body cylinder only after the tire blank on the right side is wound, the production efficiency is low, and the equipment productivity utilization rate is low.
