Description

Technical Field

[0001] The utility model relates to the technical field of PU pipe production, in particular to a drying device for PU pipe processing. Background Art

[0002] PU tube is a product formed by heating and melting plastic particles and then extruding and curing them from an extruder. However, the newly extruded product is hot and soft, and needs to be cooled and shaped in a water bath, resulting in a certain amount of moisture on its surface. It needs to be dried in time to ensure its strength in use.

[0003] The existing drying equipment places the formed PU tube in the drying equipment and performs hot air drying on it. Since a large amount of moisture remains on the surface of the PU tube, the existing drying equipment blows air on the surface of the PU tube from both sides, resulting in incomplete drying of the top and bottom of the PU tube, poor drying effect on the PU tube, and low drying efficiency.
