Background

In the prior art, the pipeline comprises a straight pipe and a bent pipe, and the corrosion prevention of the outer surface of the pipeline can be realized by spraying a corrosion prevention material such as epoxy powder on the periphery of the pipeline and then winding a corrosion prevention winding belt in a double layer mode, namely three-layer PE corrosion prevention. Taking a bent pipe as an example, the bent pipe three-layer PE anticorrosion production line clamps a bent pipe pipeline to be processed and a bent pipe with the same pipe diameter and curvature. The front of the pipeline is provided with a process pipe, and the rear of the pipeline is provided with a propulsion pipe.

The workpiece pipe to be machined is first inductively heated. Then epoxy powder spraying is carried out, and the outer winding belt is wound on a workpiece pipeline to be processed. And then the mixture is heated again by a heating ring for secondary infrared heating. And the heated workpiece pipeline continuously moves forwards after coming out of the infrared heating ring until all the workpiece pipelines are machined.

The temperature of the heated workpiece pipeline is high, and the winding belt is easy to damage due to the action of pressure and friction force when the workpiece pipeline passes through the supporting roller. Although the existing supporting roller is also provided with a water cooling device to cool the contact surface of the supporting roller, the cooling effect is not ideal, and the winding belt is still easy to damage.
