Description

Technical Field

[0001] The utility model relates to the field of UV irradiation curing, in particular to a low-temperature double-sided UV irradiation mechanism. Background Art

[0002] UV coating can be used as paint to protect the surface of products, and has the advantages of high hardness, good wear resistance, good transparency, etc. After the UV coating is applied on the surface of the product, the UV coating can be cured into a film by irradiating a UV lamp.

[0003] When the current UV tunnel furnace irradiates the sole products coated with UV coating, the length direction of the UV lamp is perpendicular to the conveying direction of the product, and the sole usually enters the UV irradiation area with the short side. The short side of the sole is fixed, and the irradiation angle of the single UV lamp installed horizontally is fixed, so the length direction of the irradiation is very limited. The short side of the sole passes through a limited UV irradiation area. Therefore, in order to ensure that there is enough UV energy, the number of lamps needs to be increased to increase the length of the irradiation area, and the energy consumption cost increases. In addition, there are gaps between the UV lamps arranged side by side, resulting in low uniformity of light received by the product as it moves forward with the conveying structure, and less UV energy accumulation, resulting in poor UV coating curing effect on the surface of the product. In addition, the current UV tunnel furnace basically only uses UV lamps set above the product, and the light is difficult to irradiate the surface below the product. Some products need to enter the UV tunnel furnace multiple times in different postures to complete the UV coating curing on all surfaces, and the production efficiency is low. Utility Model Content
