The invention discloses a double needle sewing mechanism of an intelligent double needle computer pattern sewing machine. The mechanism comprises a machine shell, a needle bar locating switching device fixedly connected with the machine shell, a first needle bar and a second needle bar which are arranged in parallel on the needle bar locating switching device, and a needle bar drive device in transmission connection with the first needle bar or the second needle bar. The lower ends of the first needle bar and second needle bar are respectively provided with sewing needles, the needle bar locating switching device locates the first needle bar or the second needle bar, and the needle bar drive device is in transmission connection with a corresponding unlocated needle bar, thereby driving thecorresponding needle bar to move up and down. Alternative working of two sewing needles is simply achieved, different color threads can be conveniently replaced for sewing, actions of the intelligentdouble needle computer pattern sewing machine are more smooth, the effect is better, production efficiency is high, and the double needle sewing mechanism has the advantages of simple structures, lowmanufacturing cost, easy control and the like and has wide utilization value of the industry.
