Description

Technical Field

[0001] This utility model relates to the field of cooling devices, specifically an environmentally friendly cable insulation layer extrusion cooling device. Background Technology

[0002] Environmentally friendly cables are cables that meet environmental protection requirements in terms of material selection, production process, and waste disposal. They typically use halogen-free, low-smoke, flame-retardant, and non-toxic materials to reduce harm to the environment and human health.

[0003] In the production process of environmentally friendly cables, the insulation layer needs to be cooled after extrusion to ensure the quality and performance of the cable. Cooling after extrusion can stabilize the shape of the insulation layer and prevent deformation or damage during subsequent processing.

[0004] Existing environmentally friendly cable insulation layers are typically cooled by passing them through a water tank using a traction device. However, during use and observation, it has been found that when the cable is immersed in the water tank, only a portion of the water level is usually in contact with the cooling water, making it difficult for the top of the cable insulation layer to be cooled quickly.

[0005] Therefore, an environmentally friendly cable insulation layer extrusion cooling device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An environmentally friendly cable insulation layer extrusion cooling device of this utility model includes a water tank, a motor installed in the middle of the water tank; multiple transport rollers are rotatably connected to the inner wall of the water tank; the output end of the motor and one of the transport rollers are fixedly connected; adjacent transport rollers are driven by belts; a water pump is installed in the middle of the water tank; the water pump and the water tank are connected by a pipe; a connecting plate is provided inside the water tank; the water pump and the connecting plate are connected by a pipe; a cooling plate is fixedly connected to the middle of the connecting plate; the cooling plate has an arc-shaped structure; the inner wall of the cooling plate is porous; through the combined action of the water pump and the cooling plate, water can be sprayed through the cooling plate to the top of the cable insulation layer, increasing the contact area between the cooling water and the cable surface, so that the cable insulation layer can be cooled uniformly.

[0008] Preferably, a slide rail is symmetrically fixed to the middle of the water tank; the connecting plate and the slide rail are slidably connected; a screw is threadedly connected through the middle of the connecting plate; the screw and the water tank are rotatably connected; an operating ring is fixed to the top of the screw; through the cooperation of the screw and the slide rail, the operator can rotate the operating ring to change the height of the cooling plate, thereby realizing the device's rapid adjustment of the cooling water spray height and angle, so that the cooling plate can meet more production needs of the cable.

[0009] Preferably, the top of the cooling plate is fixed with multiple fins; the fins are arc-shaped; after the water source in the water tank enters the interior of the cooling plate through the water pump, because the cooling plate is exposed to the air, the fins increase the contact area between the cooling plate and the air, improve the heat exchange rate between the surface of the cooling plate and the air, so that the water flow at the cooling plate can be cooled more quickly, and reduce the impact of the high temperature of the cable insulation layer itself on the water source.

[0010] Preferably, a top rod is symmetrically fixed to the top of the connecting plate; an air plate is fixed to the top of the top rod; an air pipe is connected to the top of the air plate; the inner wall of the air plate is perforated; during operation, the operator can connect an air pump to the air pipe so that the airflow passes through the air pipe and is ejected from the holes in the inner wall of the air plate. This airflow will reach the surface of the fins and cool and clean them, reducing the dust adhering to the inner wall of the fins, and at the same time accelerating the airflow around the fins, improving the cooling effect of the device on the water circulation at the cooling plate.

[0011] Preferably, multiple baffles are symmetrically fixed to the surface of the transport roller; the baffles have a wave-shaped structure; when the transport roller rotates under the drive of the motor, it will drive the baffles to rotate together. When the baffles rotate, they will increase the contact area between the transport roller and the water flow, so that the transport roller will agitate the water source in the water tank when it rotates, and the flowing water source will increase the cooling effect on the surface of the cable.

[0012] Preferably, the surface of the transport roller is provided with a guide groove; the guide groove is inclined; by providing a guide groove on the surface of the transport roller, the cable is guided by the surface of the guide groove when it is transported along the transport roller, making the transport of the cable more stable and reducing the deviation that occurs during the transport of the cable.

[0013] The advantages of this utility model are:

[0014] 1. The environmentally friendly cable insulation extrusion cooling device of this utility model, through the combined action of a water pump and a cooling plate, allows water to be sprayed onto the top of the cable insulation layer through the cooling plate, increasing the contact area between the cooling water and the cable surface, so that the cable insulation layer can be cooled evenly.

[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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, an environmentally friendly cable insulation layer extrusion cooling device is provided. A motor 12 is installed in the middle of the water tank 1. Multiple transport rollers 13 are rotatably connected to the inner wall of the water tank 1. The output end of the motor 12 and one of the transport rollers 13 are fixedly connected. Adjacent transport rollers 13 are connected by belt drive. A water pump 14 is installed in the middle of the water tank 1. The water pump 14 and the water tank 1 are connected by a pipe. A connecting plate 15 is provided inside the water tank 1. The water pump 14 and the connecting plate 15 are connected by a pipe. A cooling plate 16 is fixedly connected to the middle of the connecting plate 15. The cooling plate 16 has an arc-shaped structure and its inner wall is porous. During operation, the water tank 1 is filled with water, allowing the extruded cable to pass through the water tank 1 and the motor 12 and water pump to be started. When pump 14 and motor 12 start, multiple conveyor rollers 13 rotate under belt drive and transport the cable. The cable's surface insulation layer is immersed in water and cooled. At the same time, after pump 14 starts, it draws water from the water tank 1 and sends it to the connecting plate 15 and cooling plate 16. The cooling water is sprayed out through the holes in the inner wall of the cooling plate 16 and cools the top of the cable insulation layer. Because the cooling plate 16 has an arc-shaped structure, the water can be sprayed onto the cable surface from multiple directions, increasing the contact area between the cable and the cooling water, so that the cable insulation layer can be cooled and formed quickly. Through the combined action of pump 14 and cooling plate 16, the water can be sprayed onto the top of the cable insulation layer through the cooling plate 16, increasing the contact area between the cooling water and the cable surface, so that the cable insulation layer can be cooled evenly.

[0026] Please see Figure 2 and Figure 3 As shown, a slide rail 2 is symmetrically fixed to the middle of the water tank 1; the connecting plate 15 and the slide rail 2 are slidably connected; a screw 22 is threadedly connected through the middle of the connecting plate 15; the screw 22 and the water tank 1 are rotatably connected; an operating ring 23 is fixed to the top of the screw 22; the operator can adjust the height of the connecting plate 15 according to the thickness of the cable surface insulation layer. Specifically, by manipulating the operating ring 23, the screw 22 is rotated. When the screw 22 rotates, the connecting plate 15, along with the cooling plate 16, slides along the slide rail 2. At this time, the water pump 14 and the connecting plate 15 are connected. Plate 15 can be connected by a flexible hose. The height of the cooling plate 16 changes after it moves, which effectively controls the impact of the water sprayed from the cooling plate 16 on the surface of the cable insulation layer. At the same time, the spray angle and coverage of the water at the cooling plate 16 also change due to the height change, which can ensure that the insulation layer is fully cooled. Through the cooperation of screw 22 and slide rail 2, the operator can change the height of the cooling plate 16 by rotating the operating ring 23, realizing the rapid adjustment of the height and angle of the cooling water spray, so that the cooling plate 16 can meet more production needs of the cable.

[0027] Please see Figure 3 and Figure 4 As shown, multiple fins 3 are fixed to the top of the cooling plate 16; the fins 3 have an arc-shaped structure; after the water source in the water tank 1 enters the interior of the cooling plate 16 through the water pump 14, because the cooling plate 16 is exposed to the air, the fins 3 increase the contact area between the cooling plate 16 and the air, improve the heat exchange rate between the surface of the cooling plate 16 and the air, so that the water flow at the cooling plate 16 can be cooled more quickly, and reduce the impact of the high temperature of the cable insulation layer itself on the water source.

[0028] Please see Figure 3 and Figure 4 As shown, a top rod 4 is symmetrically fixed to the top of the connecting plate 15; an air plate 42 is fixed to the top of the top rod 4; an air pipe 43 is connected to the top of the air plate 42; the inner wall of the air plate 42 is perforated; during operation, the operator can connect an air pump to the air pipe 43 so that the airflow passes through the air pipe 43 and is ejected from the holes in the inner wall of the air plate 42. This airflow will reach the surface of the fin 3 and cool and clean it, reducing the dust adhering to the inner wall of the fin 3, and at the same time accelerating the airflow around the fin 3, improving the cooling effect of the device on the water circulation at the cooling plate 16.

[0029] Please see Figure 5 As shown, multiple baffles 5 are symmetrically fixed to the surface of the transport roller 13; the baffles 5 have a wave-shaped structure; when the transport roller 13 rotates under the transmission of the motor 12, it will drive the baffles 5 to rotate together. When the baffles 5 rotate, they will increase the contact area between the transport roller 13 and the water flow, so that the transport roller 13 will agitate the water source in the water tank 1 when it rotates, and the flowing water source will increase the cooling effect on the surface of the cable.

[0030] Please see Figure 5 As shown, the surface of the transport roller 13 is provided with a guide groove 6; the guide groove 6 is inclined; by providing a guide groove 6 on the surface of the transport roller 13, the cable will be guided by the surface of the guide groove 6 when it is transported along the transport roller 13, making the transport of the guide groove 6 more stable and reducing the deviation that occurs during the transport of the guide groove 6.

[0031] Working principle: The water tank 1 is filled with water. The extruded cable can be passed through the water tank 1 and the motor 12 and water pump 14 are started. When the motor 12 starts, multiple conveyor rollers 13 will rotate under the action of belt drive and transport the cable. The insulation layer of the cable surface will be immersed in water and cooled. At the same time, after the water pump 14 starts, it will draw water from the water tank 1 and send it to the connecting plate 15 and the cooling plate 16. The cooling water will be sprayed out through the holes in the inner wall of the cooling plate 16 and cool the top of the cable insulation layer. Because the cooling plate 16 has an arc-shaped structure, the water can be sprayed from multiple directions. Spraying water onto the cable surface increases the contact area between the cable and the cooling water, allowing the cable insulation layer to cool and solidify quickly. Operators can adjust the height of the connecting plate 15 according to the thickness of the cable insulation layer. Specifically, by manipulating the operating ring 23, the screw 22 rotates. When the screw 22 rotates, the connecting plate 15, along with the cooling plate 16, slides along the slide rail 2. At this time, the water pump 14 and the connecting plate 15 can be connected by a flexible hose. The height of the cooling plate 16 changes after it moves, effectively controlling the impact force of the water sprayed from the cooling plate 16 on the surface of the cable insulation layer. The height change causes variations in the spray angle and coverage of the water flow at the cooling plate 16, ensuring sufficient cooling of the insulation layer. Water from the water tank 1 enters the cooling plate 16 via pump 14. Because the cooling plate 16 is exposed to air, the fins 3 increase the contact area between the cooling plate 16 and the air, improving the heat exchange rate between the surface of the cooling plate 16 and the air, thus accelerating the cooling of the water flow at the cooling plate 16. During operation, an air pump can be connected to the air pipe 43, causing airflow to pass through the air pipe 43 and be ejected from the holes in the inner wall of the air plate 42. The water will reach the surface of the fin 3 and cool and clean it, reducing the dust adhering to the inner wall of the fin 3, and also accelerating the airflow around the fin 3; when the transport roller 13 rotates under the drive of the motor 12, it will drive the baffle 5 to rotate together. When the baffle 5 rotates, it will increase the contact area between the transport roller 13 and the water flow, so that the water source in the water tank 1 will be agitated when the transport roller 13 rotates; by opening the guide groove 6 on the surface of the transport roller 13, the cable will be guided by the surface of the guide groove 6 when it is transported along the transport roller 13, making the transport of the guide groove 6 more stable.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
