Technical Field
[0001] This utility model relates to the field of coating devices, specifically a device for coating the insulation layer of wires and cables. Background Technology
[0002] Cables are essential devices for power transmission and signal transmission, and their interior consists of a conductor and an insulation layer. The insulation layer is a crucial part of the cable; it wraps around the conductor and serves to isolate the conductor, prevent current leakage, prevent external interference, and protect the conductor from damage caused by the external environment.
[0003] Cable insulation layer coating mainly relies on specialized wire and cable production equipment to extrude molten insulating material onto the conductor or conductor shielding layer to form an insulation layer.
[0004] Existing cable insulation layers are typically cooled by immersion in water or spraying after being coated. However, during use and observation, it has been found that this cooling method can cause the insulation layer to be corroded by moisture before it cures, reducing its insulation performance and affecting the quality of the coating of the cable insulation layer by the device.
[0005] Therefore, a device for covering the insulation layer of wires and cables is proposed to address the above problems. Utility Model Content

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 scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a wire and cable insulation layer coating device, including a base 1, a top unwinding frame 12, a top winding frame 13, a first motor 110 mounted on one side of the winding frame 13, an extrusion discharge cylinder 14 mounted on the top of the base 1, an extrusion structure connected to the top of the extrusion discharge cylinder 14, a water tank 16 on the top of the base 1 containing cooling water, a vertical plate 15 on the top of the base 1, multiple mounting seats 17 on both sides of the vertical plate 15, UV curing lamps 18 mounted on the surface of the mounting seats 17, and convex lenses 19 symmetrically fixed to the center of the mounting seats 17, with the convex lenses 19 located between the multiple mounting seats 17. During operation, one end of the cable can be wound around the surface of the unwinding frame 12, and the other end wound onto the winding frame 13. Then, the first motor 110 can be started to... The cable is transported from the unwinding rack 12 to the extrusion discharge cylinder 14, which is equipped with an extrusion mechanism. The extrusion mechanism is an existing device used to extrude gel-like plastic onto the cable. The cable then passes through the vertical plate 15. When the UV curing lamp 18 is powered on, it emits light, which is focused onto the cable surface by the convex lens 19. The insulation layer on the cable surface is quickly cured by ultraviolet irradiation. The cable can then continue to be transported into the water tank 16 and cooled and further cured by the cooling water in the water tank 16. After the cable is removed from the water tank 16 and the surface water is drained, it can reach the winding rack 13 and be wound up. Through the combined action of the UV curing lamp 18 and the convex lens 19, the light emitted by the UV curing lamp 18 can be focused by the convex lens 19 and concentrated onto the cable surface, which speeds up the curing speed of the cable insulation layer after coating and facilitates the subsequent forming of the cable insulation layer.
[0026] Please see Figure 3 and Figure 4As shown, a second motor 2 is fixedly connected to the middle of the upright plate 15; a first gear 22 is rotatably connected to the inner wall of the upright plate 15; the output end of the second motor 2 and the first gear 22 are fixedly connected; a second gear 23 is rotatably connected to the inner wall of the upright plate 15; multiple sliding grooves 24 are formed on the surface of the second gear 23; the sliding grooves 24 are arc-shaped; the mounting base 17 and the sliding grooves 24 are correspondingly arranged and slidably fitted; the mounting base 17 and the upright plate 15 are slidably connected; when it is necessary to cover cables of different sizes with insulation, the first gear 22 and the second gear 23 can be meshed by starting the second motor 2, and the second gear 23 will rotate through... The slide 24 controls the mounting base 17, causing it to slide along the vertical plate 15. This changes the distance between the mounting base 17 and the convex lens 19, allowing the light emitted by the UV curing lamp 18 to be focused onto the cable surface through the convex lens 19. This makes the UV curing lamp 18 more flexible in curing the insulation layer of cables of different sizes. Through the cooperation of the second gear 23 and the slide 24, the second motor 2 can be started to move multiple mounting bases 17 to adjust the focus of the UV curing lamp 18. This allows the UV curing lamp 18 to cure the insulation layer of cables of different sizes, improving the flexibility and adaptability of the device in curing cable insulation layers.
[0027] Please see Figure 1 and Figure 2 As shown, a first baffle 3 is symmetrically and rotatably connected to the middle of the upright plate 15; a hydraulic cylinder 32 is provided on the top of the first baffle 3; the output end of the hydraulic cylinder 32 and the first baffle 3 are rotatably connected; the hydraulic cylinder 32 is installed on the outer wall of the upright plate 15; when the UV curing lamp 18 cures the insulation layer on the cable surface, the first baffle 3 can be rotated by activating a pair of hydraulic cylinders 32 to cover the UV curing lamp 18, reducing the ultraviolet radiation emitted by the UV curing lamp 18 to the outside world, and also reducing the scattering of light in all directions, so that more light is concentrated on the cable insulation layer, thereby improving the utilization rate of light.
[0028] Please see Figure 1 and Figure 2 As shown, a second baffle 4 is fixedly connected to the middle of the first baffle 3 near the second motor 2; the second baffle 4 and the second motor 2 are arranged correspondingly; the surface of the second baffle 4 is porous; when the first baffle 3 covers the UV curing lamp 18, the second baffle 4 will also rotate with the first baffle 3 and cover the second motor 2, reducing the pollution of the second motor 2 by dust and other impurities in the working environment. At the same time, because the surface of the second baffle 4 is porous, it also facilitates heat exchange between the second motor 2 and the outside world.
[0029] Please see Figure 5As shown, a bracket 5 is fixed to the top of the water tank 16; a fan 52 is installed at the bottom of the bracket 5; by setting the fan 52, after the cable is removed from the water tank 16, the fan 52 can be activated to dry the water stains on the surface of the cable, thereby speeding up the drying process and facilitating the subsequent winding of the cable.
[0030] Please see Figure 5 As shown, a concentrator plate 6 is installed at the bottom of the fan 52; the concentrator plate 6 is shaped like an inverted frustum; by setting the concentrator plate 6, the airflow generated when the fan 52 rotates can be concentrated and reach the cable surface through the concentrator plate 6, thereby improving the drying efficiency of the cable by the fan 52.
[0031] Working principle: One end of the cable is wound around the surface of the unwinding frame 12, and the other end is wound around the rewinding frame 13. Then, the first motor 110 can be started to transport the cable. The cable on the unwinding frame 12 will be transported to the extrusion discharge cylinder 14. The extrusion discharge cylinder 14 is equipped with an extrusion mechanism, which is an existing mechanism. The extrusion mechanism is used to extrude gel-like plastic to cover the cable. Then the cable will pass through the vertical plate 15. When the UV curing lamp 18 is powered on, it will emit light and focus it on the surface of the cable through the convex lens 19. The insulation layer on the surface of the cable will be quickly cured by ultraviolet irradiation. Then the cable... The cable can continue to be transported into the water tank 16 and cooled and further cured by the cooling water in the water tank 16. After the cable is removed from the water tank 16 and the surface water is drained, it can reach the winding rack 13 and be wound up. When it is necessary to cover cables of different sizes with insulation, the second motor 2 can be started to make the first gear 22 and the second gear 23 mesh. When the second gear 23 rotates, it will control the mounting base 17 through the slide groove 24, so that the mounting base 17 will slide along the upright plate 15, so that the distance between the mounting base 17 and the convex lens 19 will change, thereby causing the UV curing lamp 18 to emit light. The light can be focused onto the cable surface by the convex lens 19, making the UV curing lamp 18 more flexible in curing the insulation layer of cables of different sizes. When the UV curing lamp 18 is curing the insulation layer on the cable surface, the first baffle 3 can be rotated by activating a pair of hydraulic cylinders 32 to cover the UV curing lamp 18, reducing the radiation of ultraviolet rays emitted by the UV curing lamp 18 to the outside world, and also reducing the scattering of light in all directions, so that more light is concentrated on the cable insulation layer. When the first baffle 3 covers the UV curing lamp 18, the second baffle 4 will also rotate with the first baffle 3 and cover the second baffle 4. The second motor 2 is covered to reduce the contamination of the working environment by dust and other impurities during operation. At the same time, the porous surface of the second baffle 4 facilitates heat exchange between the second motor 2 and the outside environment. The fan 52 allows the cable to be dried after it is removed from the water tank 16, thus speeding up the drying process and facilitating subsequent cable winding. The concentrator 6 concentrates the airflow generated by the fan 52 to the cable surface, improving the drying efficiency of the fan 52.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
