Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipe production, in particular to a PVC pipe rapid cooling and shaping device. Background Art

[0002] PVC pipes are usually manufactured by extrusion molding process. After the PVC pipe is extruded from the pipe extruder, the temperature is high, and the PVC pipe needs to be quickly cooled to make it fixed. The existing cooling device usually sprays water on the surface of the PVC pipe to cool it down by spraying water, so that it can be quickly cooled and fixed.

[0003] However, after the traditional cooling device sprays water to cool the PVC pipe, a large amount of cooling water droplets will adhere to the outer surface of the PVC pipe, and the water droplets will drip onto the surrounding workshop floor as the PVC pipe moves subsequently, which is inconvenient to clean up; and because the cooling water is usually recycled, the cooling water contains certain impurities. If the cooling water attached to the surface of the PVC pipe is not removed, after the cooling water on the surface of the PVC pipe is completely dried, water stains are likely to be left on the outer surface of the PVC pipe, increasing the workload of subsequent cleaning of the PVC pipe surface. Summary of the invention

[0004] The utility model aims to solve the deficiencies in the prior art and provide a PVC pipe rapid cooling and shaping device.
