The invention discloses a double-head elastic sleeve feeding mechanism. The mechanism comprises a base, an air cylinder, a movable sliding block and a bottom plate, wherein the base comprises a bottombase and a cover plate, a sliding groove is formed in the middle of the bottom base, the bottom base and the air cylinder are both fixedly arranged on the bottom plate, the movable sliding block is fixedly connected to an extending rod of the front end of the air cylinder, the bottom of the bottom plate is sequentially provided with a forward elastic sleeve discharging port and a reverse elasticsleeve air blowing port which both penetrate to the sliding groove along the length direction of the sliding groove, the cover plate is sequentially provided with a forward elastic sleeve air blowingport, a elastic sleeve feeding port and a reverse elastic sleeve discharging port along the length direction of the sliding groove, two material shifting holes are formed in the movable sliding block,the distance between the two material shifting holes is equal to the distance between the elastic sleeve feeding port and forward elastic sleeve air blowing port as well as the distance between the elastic sleeve feeding port and the reverse elastic sleeve discharging port, and the two material shifting holes correspond to the elastic sleeve feeding port and the reverse elastic sleeve dischargingport in position. According to the mechanism, elastic sleeves can be distributed, so that the elastic sleeves can be reversed when entering the next working procedure, so that the mounting of the forward and reverse elastic sleeves is realized, and the working efficiency is improved.
