Description

Technical Field

[0001] The utility model relates to the technical field of cable production and processing, in particular to ultraviolet radiation cross-linking equipment. Background Art

[0002] UV irradiation cross-linking equipment is a kind of equipment used for processing cables. The process flow of UV irradiation cable cross-linking equipment is to use UV light as the radiation source, extrude and coat the mixed photo-crosslinked polyolefin ingredients on the conductive core, and then immediately enter the special irradiation equipment for molten photo-crosslinking. When the insulating material is irradiated by UV light, the polymer chains in it begin to break and form free radicals, which combine with each other to form a cross-linked structure, thereby making the molecular structure of the insulating material more stable and improving the heat resistance and electrical resistance of the cable. After the insulation core after photo-irradiation cross-linking is cooled and other subsequent processing is carried out, the photo-crosslinked polyolefin insulated wire and cable products can be obtained.

[0003] A UV irradiation cross-linking device disclosed in Chinese patent CN212860127U includes an extruder, an irradiator located downstream of the extruder, a cooling water tank located downstream of the irradiator, and a line stabilizing device located between the irradiator and the cooling water tank, wherein the line stabilizing device includes a roller and a bracket for supporting the roller, the roller is rotatably connected to the bracket, and the rotating shaft is horizontally arranged, the outer peripheral surface of the roller is provided with a limiting groove for embedding a power supply line along the circumference of the roller, and the central axis of the outlet of the irradiator is circumscribed to the limiting groove.

[0004] However, the UV radiation cross-linking equipment in the prior art still has the following problems during actual use:

[0005] The ultraviolet irradiator is a device that changes the polymer linear structure into a body mesh structure after irradiation processing. The ultraviolet irradiator is directly connected in series to the extruder head. The wire is extruded through the extruder head and directly enters the irradiator for irradiation, and then enters the cooling water tank for cooling and curing. In addition, the cooling method of the ultraviolet irradiation cross-linking equipment also needs to be air-cooled. Some thinner wires and cables will cause single-line jitter after entering the ultraviolet irradiator due to the strong wind force of the air-cooling exhaust port. When the amplitude of the jitter exceeds the effective irradiation distance of the ultraviolet irradiator, it will cause uneven irradiation. The thermal extension value fluctuates, and serious cases will cause the wire to be unqualified. In the prior art, a roller with a groove is generally used to support the cable core to reduce the jitter amplitude of the core. However, since the wind force of the air-cooling exhaust port has not changed, the jitter of the core still exists, which will make the thermal extension value uniformity of the core insulation layer poor, thereby affecting the quality of the core.

[0006] Therefore, the present application proposes an ultraviolet light irradiation cross-linking device to solve the above problems. Utility Model Content

[0040] The working process of the utility model is as follows:

[0041] S1. When in use, the cable core 4 passes between the first roller 202 and the second roller 206, then enters the radiation cross-linking machine 1 through the inlet pipe 13, and passes out from the output pipe 14. While the radiation cross-linking machine 1 irradiates the cable core 4, cooling air enters from the air inlet pipe 121, passes through the air inlet hole 122 and the ventilation hole 112, and then blows toward the cable core 4 from the connecting pipe 15 to cool the cable core 4;

[0042] S2. When the cable core 4 vibrates due to wind, it drives the trigger mechanism 2 to slide on the limit mechanism 3. When the vibration amplitude is small and does not exceed the effective irradiation range, the trigger column 204 slides in the first slide groove 304.

[0043] S3. When the shaking amplitude is large, the trigger column 204 slides from the first slide groove 304 into the second slide groove 305. During the sliding process, the trigger column 204 will toggle the dial plate 114, and the dial plate 114 drives the rotating member 111 to rotate through the connecting rod 113, so that the ventilation hole 112 and the air inlet hole 122 are staggered, reducing the air intake, thereby reducing the wind force, and then weakening or eliminating the shaking of the cable core 4, ensuring the uniformity of the thermal extension value of the insulation layer of the cable core 4, and improving the quality of the cable core 4;

[0044] S4, when the trigger column 204 slides in the second slide groove 305, it moves the dial plate 114 and then passes through the first rubber sheet 307 to enter the third slide groove 306, slides along the third slide groove 306 and finally passes through the second rubber sheet 308 to return to the first slide groove 304;

[0045] S5, the kinetic energy of the trigger column 204 and the shaking cable core 4 after being slowed down by the first rubber sheet 307 and the second rubber sheet 308 is consumed by the first rubber sheet 307 and the second rubber sheet 308, and the shaking amplitude of the cable core 4 is further reduced when the wind force weakens, thereby ensuring that the cable core 4 is always within the effective irradiation range of the irradiation cross-linking machine 1 during the irradiation process;

[0046] S6. The irradiated cable core 4 passes through the output tube 14 and then proceeds to the subsequent process.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] The ultraviolet light irradiation cross-linking equipment is provided with an adjustment component 11 and a limit mechanism 3. When the vibration amplitude of the cable core 4 is large, the air intake is reduced, thereby reducing the wind force, and further weakening or eliminating the vibration of the cable core 4, ensuring the uniformity of the thermal extension value of the insulation layer of the cable core 4, and improving the quality of the cable core 4. At the same time, the kinetic energy of the trigger column 204 and the vibrating cable core 4 is consumed by the first rubber sheet 307 and the second rubber sheet 308, and the vibration amplitude of the cable core 4 is further weakened when the wind force is weakened, thereby ensuring that the cable core 4 is always in the effective irradiation range of the irradiation cross-linking machine 1 during the irradiation process.
