Abstract

The invention relates to an ultraviolet radiation crosslinking device, an optical radiation wire and a production method thereof, which relate to the technical field of wire production. The ultraviolet radiation crosslinking device comprises a case, a radiation cylinder, ultraviolet light sources and a driving assembly, wherein the radiation cylinder is arranged in the case; the case is provided with a wire inlet and a wire outlet; a wire penetrates through the center of the radiation cylinder; a plurality of ultraviolet light sources are fixed on the inner wall of the radiation cylinder; thedistribution direction of the ultraviolet light sources is consistent with the penetration direction of the wire; the plurality of ultraviolet light sources are uniformly arranged at intervals and form a circle; the driving assembly is arranged between the inner wall of the case and the outer wall of the radiation cylinder; and the driving assembly is used for driving the radiation cylinder and the ultraviolet light sources to rotate around the wire in a reciprocating manner. The device has the effects that the structure is stable and firm, ultraviolet radiation is more uniform, and the quality of the manufactured wire is better.

Description

technical field [0001] The invention relates to the technical field of electric wire production, in particular to an ultraviolet light irradiation crosslinking device, a light radiation electric wire and a production method thereof. Background technique [0002] After the wire insulating layer is irradiated with ultraviolet light, the molecular structure of the insulating layer rubber can be further changed, making its molecular structure change from linear to mesh, and the insulating layer has stronger adhesion, is not easy to break at high temperature, and has excellent flexibility and tensile strength. better. [0003] A Chinese invention patent with the announcement number CN206322524U has been retrieved, which discloses an ultraviolet radiation crosslinking device for cable production, including a box body, which has a first cover and a first reflective surface with a semi-elliptical arc in cross section. mirror, a second casing, a second reflective mirror with a semi-...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: although the ultraviolet radiation crosslinking device has played a certain light-gathering effect through the first reflector and the second reflector, the insulating layer of the wire is close to the first ultraviolet light source and the second reflector. The radiation intensity received by the part of the two-ultraviolet light source is high, but there will still be a certain attenuation after the light is reflected by the first reflector and the second reflector. This indirect irradiation method makes other parts of the wire insulation layer suffer The irradiation intensity is low, so the flexibility and tensile strength of the insulating layer treated by the ultraviolet radiation crosslinking device will have local inconsistencies, which will lead to wire quality problems, so it needs to be improved
