Abstract
The invention discloses a pneumatic and mechanical hybrid tuck-in selvage mechanism. The pneumatic and mechanical hybrid tuck-in selvage mechanism is characterized by comprising a mechanical part and a pneumatic part. For the mechanical part, power is transferred by a weaving machine to a transmission shaft through a synchronous belt and a drive gear to drive a cam set to rotate, a conjugate cam drives a nozzle part and a crochet hook to move front and back through a roller stand and a hollow shaft, and a central cam controls the crochet hook to enter into a cloth-fell timely through a roller swing arm and a swing shaft and the like. For the pneumatic part, after the weaving machine carries out wefting insertion, an electromagnetic valve moves, and a yarn end is blown into a yarn end holding hole by the nozzle. When the yarn end is opened for next wefting insertion, the crochet hook enters into the cloth-fell at the same time. When the crochet hook hole enters into the opening of the nozzle part to move right below the yarn end holding hole, the electromagnetic valve moves, the nozzle blows the yarn end into the crochet hook hole, and then the crochet hook carries the yarn end to move backward to hook the yarn end into the cloth-fell to accomplish edgefold for one time. The pneumatic and mechanical hybrid tuck-in selvage mechanism provided by the invention is stable and reliable in tuck-in selvage, neat and attractive in selvage, is suitable for an air jet loom to weave and can realize an ideal weaving effect.
