Description

Technical Field

[0001] This utility model relates to the field of duct processing technology, specifically an automatic spiral duct machine. Background Technology

[0002] Spiral duct machine is a machine that produces spiral ducts, also known as spiral seam thin-walled pipes. Spiral ducts are thin-walled pipes with spiral seams made by rolling metal strips. They have the advantages of being weld-free, leak-proof, and water-proof. They are mostly used for air supply and bulk material transportation. Spiral ducts are a new type of round duct that has recently emerged. Because the area of ​​a circle is larger than that of a square or rectangular duct for the same perimeter, and there are no dead corners, they are widely used in central air conditioning systems, indoor air purification, environmental protection and other industries.

[0003] Most existing spiral duct machines do not have a mechanism for recycling waste liquid from spiral tube production. This results in a large amount of waste liquid adhering to the surface of the duct after processing, and debris adhering to the surface after cutting. The waste liquid mixed with cutting debris will stick to the surface of the duct, affecting the subsequent use of the duct machine. Existing automatic duct cleaning mechanisms cannot completely conform to the duct surface during use and are not convenient for guiding waste residue, thus affecting the cleaning effect.

[0013] (III) Beneficial Effects

[0014] This utility model provides an automatic spiral duct machine. It has the following beneficial effects:

[0015] 1. When in use, the bearing block is connected to the external cooling mechanism via the support plate on the side wall. The roll material passes between cleaning rod A and cleaning rod B. Under the action of the tension spring, cleaning rod A relies solely on cleaning rod B. The drive motor drives the power shaft to rotate via the toothed belt. The power shaft drives the power wheel to rotate. The power wheel drives the cleaning rod A to rotate via the connecting wheel. At the same time, the bottom of the power shaft drives the cleaning rod B to rotate via the connecting wheel. The cleaning rods A and B rotate in the same direction to clean the surface of the roll material. This solves the problem that waste liquid mixed with cutting debris will stick to the surface of the duct and affect the subsequent use of the duct machine. It has the advantage of making it easy to clean the surface of the duct.

[0016] 2. When using this automatic spiral duct cleaning machine, pull up the moving frame. The moving frame drives the adjusting block to move above the limiting claw. Under the action of the return spring, the limiting claw limits the cleaning rod A. This solves the problem that the existing automatic duct cleaning mechanism cannot fully fit the duct surface and is inconvenient to guide waste residue when in use. It has the advantage of being easy to fit the duct surface. Attached Figure Description
