Description

Technical Field

[0001] The utility model discloses a heating device for ultraviolet irradiation cross-linking equipment, and relates to the field of ultraviolet irradiation cross-linking equipment. Background Art

[0002] UV radiation cross-linking technology is a manufacturing technology. Its principle is to add an appropriate amount of photo-cross-linking sensitizer to the base resin mainly composed of polyolefins. The polyolefin material is transparent when heated and extruded, and the UV radiation is focused and transmitted into the material. The high-energy UV light triggers the photosensitizer to form free radicals and further induces the polyolefin units to produce macromolecular free radicals. The free radicals form cross-linked polyolefin materials through bonding, and the high-performance materials are formed after cooling after irradiation modification.

[0003] In the Chinese patent with publication number CN220584985U, a UV irradiation cross-linking device for cable production is mentioned. The device has a simple structure and an ingenious design. The device separates the feeding component from the traditional UV irradiation cross-linking device body, and then uses the discharging component to realize the uniform feeding of the cable to be cross-linked. Since the light temperature is constant, when the speed can be controlled, the cross-linking of the cable to be cross-linked will be relatively successful, and there is no problem of polyethylene falling due to high temperature caused by staying. When the feeding speed is uniform, the phenomenon of temperature mismatch with cross-linking can be improved; however, in the prior art, the cable is not heated evenly enough, resulting in poor heating effect, affecting the subsequent irradiation effect of the cable, and also reducing the quality of the cable. In addition, the irradiation of the cable is not comprehensive enough, so that the cable cannot be uniformly irradiated by ultraviolet light. Therefore, we introduce a heating device for UV irradiation cross-linking equipment. Utility Model Content
