The invention provides a looping device for steel wires in a tire. A first guide wheel set and a second guide wheel set are arranged for guidance, a first transportation wheel set is arranged for conveying the guided steel wires, the first transportation wheel set conveys the steel wires to a second transportation wheel set for slow conveying, the second transportation wheel se conveys the steel wires to a guide semi-ring, then the steel wires are conveyed downwards slowly through the guide semi-ring, the steel wires are bent bit by bit through a looping head of a looping air cylinder till the steel wires are bent to a circle when conveyed, then the steel wires are cut off by a cutting head of the looping air cylinder to fall into a storage box, the first transportation wheel set, the second transportation wheel set and the looping air cylinder are all precisely controlled by a looping controller, and looping can be carried out efficiently and fast. The height of the first transportation wheel set, the second transportation wheel set, the first guide wheel set and the second wheel set can be adjusted according to actual conditions, and great convenience is achieved. The looping device is simple in structure and easy to operate, the steel wires can be looped efficiently and fast, and the looping device is suitable for production.
