[0027] Working principle: During use, place the metal plate on the roller conveyor 201, turn on the roller conveyor 201 to convey the metal plate to the support plate 202. At this time, the metal plate is laid flat on the support plate 202. Turn on the first cylinder 302 to drive the lifting seat 303 to move downward, so that the first rotating shaft 305 moves downward. The downward movement of the first rotating shaft 305 drives the roller 306 to move downward and press on the metal plate. Turn on the first motor 304 to drive the first rotating shaft 305 to rotate, and then drive the roller 306 to rotate. The rotation of the roller 306 pushes the metal plate to move until the right end of the metal plate reaches the folding distance. Then turn on the fourth motor 601 and the second cylinder 604 at the same time, so that the pushing roller 606 always abuts against the bottom of the right end of the metal plate, and then push the metal plate to bend. After one side is bent, turn on the reverse rotation of the fourth motor 601 and then retract the second cylinder 604 to reset the pushing roller 606. Then turn on the first motor 304 to drive the first rotating shaft 305 to rotate, so that the roller 306 continues to push the metal plate to move rightward by the distance of one fold edge, and perform folding again. After folding three times, the air duct is formed. At this time, the welding head 404 is exactly aligned with the joint of the air duct. Turn on the second motor 405 to drive the first lead screw 402 to rotate, and then drive the sliding seat 403 to move, so that the welding head 404 welds along the joint inside the air duct. After welding is completed, turn on the third motor 501 to drive the second lead screw 504 to rotate, so that the material pushing plate 502 moves to push the air duct out.

[0028] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.
