Description

Technical Field

[0001] The present invention relates to a device and a method, and in particular to a spiral tube winding device and a method. Background Art

[0002] The spiral tube rolling machine is a special equipment for manufacturing spiral tubes. It is used to roll aluminum alloy plates, steel plates, aluminum plates, plastic plates, stainless steel plates and other plates into spiral tube shapes. It is suitable for ventilation, exhaust, air conditioning and refrigeration, environmental exhaust, equipment chimneys and other fields that require spiral tubes.

[0003] The existing spiral tube reels on the market currently have poor tube reeling effects when rolling spiral tubes. The outer circle precision of the rolled spiral tubes is low and they are prone to rebound deformation. In addition, the existing spiral tube reels only have a power source at the conveying device, and the power source is used to provide power to the conveying device to convey the plate to be rolled, while the device for rolling the plate is not provided with a power source. The lack of a power source in the rolling device makes it impossible for the existing spiral tube reels to roll thicker plates. Thicker plates cannot be successfully rolled and formed by the rolling device simply relying on the forward conveying force of the conveying device. Therefore, the existing spiral tube reels can only roll thinner plates and have a smaller scope of application. Summary of the invention
