A tire building machine is a common device in the rubber industry, and generally requires assembling a carcass, a tire bead and other functional rubber layers on a building drum in sequence during production, and then manufacturing the components into a shape of a green tire by extrusion. The known tyre building machines are generally provided with a building drum and a turntable which can slide in a direction close to or away from the building drum, the sliding path of the turntable being horizontal and perpendicular to the axis of the building drum. The rotating table slides towards the direction close to the forming drum, the tire body is attached to the forming drum, and the tire body can be wound on the forming drum along with the rotation of the forming drum. After the tyre body is wound, the rotating table needs to slide in the direction away from the forming drum, so that a space is reserved for assembling the tyre bead and other functional rubber layers.
