Technical Field
[0001] This utility model relates to the field of ultraviolet irradiation technology for cables, specifically to an ultraviolet irradiation crosslinking device for cables. Background Technology
[0002] Wires and cables are essential components for transmitting electrical energy, information, and manufacturing various electrical appliances and instruments. They are fundamental products for electrification and information technology, and are widely used in various industries and households. Due to their excellent properties and reasonable cost-effectiveness, polymer materials are widely used as the sheathing layer of cables. With social development, higher demands are being placed on wires and cables in microelectronics, home appliances, automobiles, aviation, communications, power systems, transportation, and construction. Conventional wires and cables often struggle to meet these requirements. Cross-linking modification can significantly improve the operating temperature, solvent resistance, environmental aging resistance, and crack resistance of wires and cables.
[0003] Irradiation crosslinking technology refers to the use of ultraviolet light to crosslink polyolefin materials. Polyolefin materials are transparent when heated and extruded. Ultraviolet light is focused and transmitted into the material. High-energy ultraviolet light triggers photosensitizers to form free radicals, which further induce polyolefin units to generate macromolecular free radicals. The free radicals form crosslinked polyolefin materials through bonding.
[0004] Most existing irradiation crosslinking devices are fixed, requiring manufacturers to equip them with cable processing equipment of matching height for operation. This makes it inconvenient to adjust the height of the irradiation crosslinking device according to the manufacturer's existing equipment. Furthermore, since most irradiation lamps are fixed inside the device, the irradiation range is limited, which can easily lead to uneven ultraviolet light illumination and affect the uniformity of crosslinking.
[0005] Therefore, an ultraviolet irradiation crosslinking device for cables is proposed to solve the problems mentioned above. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a cable ultraviolet irradiation crosslinking device, which can solve the problems of inconvenience in adjusting the height of the irradiation crosslinking device according to the manufacturer's existing equipment, and the fact that most irradiation lamps are fixed inside the device, limiting the irradiation range and easily leading to uneven ultraviolet light illumination, thus affecting the uniformity of crosslinking.
[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a fixed block and several support columns. A support plate is fixedly connected to the outer surface of the fixed block. A motor is fixedly connected to the upper surface of the support plate. A connecting shaft is fixedly connected to the output end of the motor. A first worm gear is symmetrically fixedly connected to the outer surface of the connecting shaft. A threaded rod is rotatably connected inside the fixed block. A first worm wheel is fixedly connected to the outer surface of the threaded rod, and the first worm wheel meshes with the first worm gear. A movable rod is threadedly connected to the outer surface of the threaded rod, and a device base is fixedly connected to the top end of the movable rod.

[0009] Preferably, an inner groove is provided on one side of the irradiation chamber, and a second worm gear is rotatably connected inside the inner groove, the second worm gear being meshed with the second worm.
[0010] Preferably, a plurality of connecting rods are fixedly connected to the other side of the second worm gear, and an ultraviolet lamp ring is fixedly connected to the other end of the connecting rods. The other end of the ultraviolet lamp ring is rotatably connected to the other side of the interior of the irradiation chamber.
[0011] Preferably, each of the support columns has a sliding column slidably connected to its outer surface, and the top end of each sliding column is fixedly connected to the lower surface of the device base.
[0012] Preferably, a horizontal plate is fixedly connected to the outer surface of the movable rod, and the other end of the horizontal plate is fixedly connected to the sliding column.
[0013] Preferably, a limiting plate is fixedly connected to the upper surface of the support plate, and the interior of the limiting plate is rotatably connected to the connecting shaft.
[0014] Compared with the prior art, this utility model provides a cable ultraviolet irradiation crosslinking device, which has the following beneficial effects:
[0015] 1. By incorporating a motor, the first worm gear drives the first worm wheel to rotate, causing the threaded rod to rotate inside the fixed block.

[0016] 2. By setting up an electric push rod, the second worm gear drives the second worm wheel to rotate, which in turn drives the ultraviolet lamp ring to rotate inside the irradiation box, so as to fully irradiate the cables entering the box, ensuring the uniformity of ultraviolet light irradiation and improving the uniformity of irradiation crosslinking.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example:
[0025] Please see Figure 1 - Figure 4The cable ultraviolet irradiation crosslinking device in this embodiment includes a fixed block 1 and several support columns 19. A support plate 2 is fixedly connected to the outer surface of the fixed block 1. A motor 3 is fixedly connected to the upper surface of the support plate 2. A connecting shaft 4 is fixedly connected to the output end of the motor 3. A first worm gear 5 is symmetrically fixedly connected to the outer surface of the connecting shaft 4. A threaded rod 6 is rotatably connected inside the fixed block 1. A first worm wheel 7 is fixedly connected to the outer surface of the threaded rod 6. The first worm wheel 7 meshes with the first worm gear 5. A movable rod 8 is threadedly connected to the outer surface of the threaded rod 6. A device base 9 is fixedly connected to the top end of the movable rod 8.
[0026] Each support column 19 has a sliding column 20 slidably connected to its outer surface. The top of the sliding column 20 is fixedly connected to the lower surface of the device base 9. The outer surface of the movable rod 8 is fixedly connected to a horizontal plate 21. The other end of the horizontal plate 21 is fixedly connected to the sliding column 20. The upper surface of the support plate 2 is fixedly connected to a limiting plate 22. The inside of the limiting plate 22 is rotatably connected to the connecting shaft 4.
[0027] Among them, the motor 3 above the start support plate 2 drives the connecting shaft 4 to rotate inside the limit plate 22 through the output end of the motor 3, so that the connecting shaft 4 drives the two first worm gears 5 to rotate together. Since the first worm gear 5 is meshed with the first worm wheel 7, when the first worm gear 5 rotates, it will drive the first worm wheel 7 to rotate together. The first worm wheel 7 drives the threaded rod 6 to rotate inside the fixed block 1. When the threaded rod 6 rotates, the movable rod 8 drives the device base 9 to rise and fall.
[0028] At this time, since there is a horizontal plate 21 on the outer surface of the movable rod 8, and the horizontal plate 21 is connected to multiple sliding columns 20, the movable rod 8 will not rotate. The sliding columns 20 are supported by multiple support columns 19 to slide, so that the overall structure is stable and the device base 9 is prevented from shaking.
[0029] An irradiation chamber 10 is fixedly connected to the upper surface of the device base 9. A square block 11 is fixedly connected to the top of the irradiation chamber 10. An electric push rod 12 is fixedly connected inside the square block 11. A connecting plate 13 is fixedly connected to the output end of the electric push rod 12. A second worm gear 14 is fixedly connected to the lower surface of the connecting plate 13. An inner groove 15 is opened on one side of the interior of the irradiation chamber 10. A second worm wheel 16 is rotatably connected inside the inner groove 15. The second worm wheel 16 meshes with the second worm gear 14. Several connecting rods 17 are fixedly connected to the other side of the second worm wheel 16. An ultraviolet lamp ring 18 is fixedly connected to the other end of the connecting rod 17. The other end of the ultraviolet lamp ring 18 is rotatably connected to the other side of the interior of the irradiation chamber 10.
[0030] When the cable passes through the inside of the irradiation box 10, the electric push rod 12 inside the square block 11 is activated. The output end of the electric push rod 12 drives the connecting plate 13 to slide inside the inner groove 15. The connecting plate 13 drives the second worm gear 14 to move. Since the second worm gear 14 is meshed with the second worm wheel 16, when the second worm gear 14 moves, it drives the second worm wheel 16 to rotate inside the inner groove 15. The second worm wheel 16 drives the connecting rod 17 and the ultraviolet lamp ring 18 to rotate together inside the irradiation box 10, so that the ultraviolet light is evenly irradiated on the outside of the cable.
[0031] In the above embodiment, the ultraviolet irradiation crosslinking device uses an ultraviolet radiation source and an ultraviolet lamp ring 18 containing ultraviolet lamps to uniformly irradiate the outer layer of the cable or the surface of the material, causing the polymer molecular chains to undergo a crosslinking reaction. The high energy of the ultraviolet light breaks the chemical bonds of the polymer, leading to the formation of new chemical bonds between molecules, thereby improving the mechanical strength, heat resistance, and chemical corrosion resistance of the material. At the same time, compared with traditional thermal crosslinking, ultraviolet irradiation crosslinking has higher efficiency and shorter processing time, which can significantly improve the efficiency of the production line and reduce energy consumption.
[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
