Description

Technical Field

[0001] The utility model relates to the technical field of spraying and drying integrated machines, in particular to a zinc steel railing spraying and drying integrated machine. Background Art

[0002] Spray painting is a common and inexpensive surface treatment process, and it makes the surface of parts smooth, uniform and colorful, thereby improving the appearance of the product. Drying refers to the process of removing solvents and retaining solid content in some way. It usually refers to the process of introducing hot air to evaporate and carry away the moisture in the material. A spray-drying machine is a device that can spray and dry the workpiece in one machine. Zinc-steel railings are balcony guardrails made of zinc alloy materials. They have the advantages of high strength, high hardness, exquisite appearance and bright colors. Zinc-steel railings require the use of a spray-drying machine for processing during production.

[0003] In actual use, the existing zinc-steel railing spraying and drying integrated machine sprays and dries the surface of the zinc-steel railing by turning the zinc-steel railing over many times, which can easily cause inconsistent drying speed of the surface paint and uneven spraying and drying effect. The paint surface dries unevenly, resulting in wrinkles, deformation or shrinkage on the paint film surface, thereby affecting the performance and aesthetics of the overall coating. Therefore, we propose a zinc-steel railing spraying and drying integrated machine to solve the above problems. Utility Model Content
