During the manufacturing process, the guardrail needs to be painted and plastered to make the guardrail itself have a certain aesthetic value. After the painting and plastering operation is completed, the paint needs to be quickly dried. A guardrail drying device is proposed in prior art announcement number CN216308548U. It includes an upper shell, the bottom of the upper shell is fixedly connected to the lower shell, and the right side of the upper shell is fixedly connected to the right shell.
