The fixing mechanism for the anti-corrosion air duct cutting machine of this embodiment can stably clamp the anti-corrosion air duct and ensure the stable feeding of the anti-corrosion air duct. The mounting structure of the first roller 204 and the movable plate 203 is conventional technology, and specifically, a U-shaped wheel seat can be fixedly installed on the surface of the movable plate 203, and the first roller 204 can be rotatably mounted on the U-shaped wheel seat through a rotating shaft.

[0018] When the fixing mechanism of a corrosion-resistant air duct cutting machine of the present embodiment is in operation, it is assembled on the cutting machine, the cutting head of the cutting machine is aligned with the cutting groove 102 on the base 1, the corrosion-resistant air duct is placed on the base 1, and the movable plate 203 is pushed by the second driving cylinder 208 so that the first roller 204 abuts against the corrosion-resistant air duct, and the push rod 201 is pushed so that the push rod 201 abuts against the corrosion-resistant air duct, and the corrosion-resistant air duct moves along the base 1. After the corrosion-resistant air duct is in place, the first driving cylinder 207 pushes the first push plate 205 so that the first push plate 205 presses the corrosion-resistant air duct to fix the corrosion-resistant air duct. Preferably, the first push plate 205 is provided with a rubber pad 206 to Increase friction to prevent the corrosion-resistant air duct from moving. After cutting is completed, the first push plate 205 moves away from the corrosion-resistant air duct and pushes the push rod 201.
