The alignment baffle 541 of the alignment stop mechanism 54 is lifted, and the alignment push rod 531 of the alignment pushing mechanism 53 moves forward, and contacts with the tail end of the plastic pipe and advances until the front end of the plastic pipe abuts against the alignment baffle 541. The feeding and taking air cylinder 623 of the plastic pipe feeding mechanism 62 drives the feeding and taking air claw 624 to descend, the feeding and taking air claw 624 stretches into the aligned discharging groove 522 to clamp and take out the aligned plastic pipe, the movable end of the overturning driving piece 6251 retracts to drive the swinging rod 6224 to swing backwards, so that the overturning plate 6223 is driven to overturn 90 degrees, then the plastic pipe in the feeding and taking air claw 624 is overturned and is horizontally overturned to be vertical, the sliding plate driving piece 66 drives the plastic pipe feeding mechanism 62 to move forwards, and the plastic pipe which is uniformly oriented and aligned and has an upward upper interface is transferred into the material receiving jig, so that the transfer or assembly of the plastic pipe is facilitated.
