Tire building drum

The utility model relates to the technical field of tire building, and discloses a tire building drum. A synchronous driving assembly in a machine box drives a first push-pull rod in a drum shaft and a second push-pull rod outside the drum shaft to move synchronously, the first push-pull rod drives a first anti-wrapping rod mechanism, the second push-pull rod drives a second anti-wrapping rod mechanism, synchronous rising and falling of the first anti-wrapping rod mechanism and the second anti-wrapping rod mechanism are achieved, and therefore anti-wrapping rising and falling actions are achieved; the first push-pull rod and the second push-pull rod are both of a rod-shaped structure, the structure is simple, the manufacturing cost is low, the structural strength and rigidity are large, control is convenient, the push-pull precision and stability are improved, the integration degree of the synchronous driving assembly is high, the overall size of the machine box can be reduced, the second push-pull rod is loc
