[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1

[0023] See also Figure 1-5 The utility model provides a technical solution: a cable extrusion cooling molding device, a base 1, the base 1 serves as the basic support of the entire device, and stably carries the various components above. The top surface of the base 1 is fixed with an extrusion chamber 2 and a vertical plate 3 by bolts. The vertical plate 3 is fixed to the base 1 by welding to ensure its verticality and stability. The top surface of the vertical plate 3 is fixed with a motor 4 by bolts. The motor 4 serves as a power source to provide the required power for the entire device. The output end of the motor 4 is installed with a driving gear 5 through a coupling. This connection method ensures the stability and reliability of power transmission. The inner wall of the extrusion chamber 2 is rotatably connected to a hollow cylindrical shaft 7 through a bearing, so that the hollow cylindrical shaft 7 can rotate freely in the extrusion chamber 2.

[0024] The driven gear 6 is fixedly mounted on the surface of the hollow cylindrical shaft 7, and the driving gear 5 meshes with the driven gear 6 to form a gear transmission mechanism, thereby realizing effective transmission of power. The surface of the hollow cylindrical shaft 7 is also fixedly mounted with a spiral blade 8 through a key connection. When the hollow cylindrical shaft 7 rotates, the spiral blade 8 can push the molten rubber forward. One end of the extrusion chamber 2 is connected to the molding chamber 9 through a flange. One side of the molding chamber 9 is also connected to the outlet pipe 10 through a flange, which is convenient for the export of the finished cable. A wire inlet hole 11 is provided on the side of the vertical plate 3, and the wire inlet hole 11 is connected to the hollow cylindrical shaft 7, ensuring that the cable can smoothly enter the hollow cylindrical shaft 7 and be wrapped by the molten rubber. The top surface of the extrusion chamber 2 is connected to a feed hopper 12 through a flange. The feed hopper 12 is designed as a trumpet-shaped structure, which is convenient for the addition of molten rubber and can ensure the uniform supply of rubber. A cooling pipe 13 is fixedly mounted inside the molding chamber 9 through bolts. The cooling pipe 13 is made of a metal material with good thermal conductivity, such as copper or aluminum alloy, to ensure efficient heat exchange. The surface of the vertical plate 3 is fixedly mounted with a bracket 14 by welding. The bracket 14 is designed as an "L"-shaped structure, which enhances the stability and bearing capacity of the device. The bracket 14 is fixedly connected to the cooling pipe 13 by bolts, ensuring the stability and reliability of the cooling pipe 13.

[0025] See also Figure 1-5 The surface of the cooling pipe 13 is connected to the water tank 15 through a flange. The interior of the water tank 15 is designed with a large number of heat dissipation fins, which increases the heat exchange area and improves the cooling efficiency. The surface of the water tank 15 is fixed with heat conducting sheets 16 by bolts. The heat conducting sheets 16 are arranged at equal distances on the surface of the water tank 15.

[0026] Uniform heat transfer is ensured. The heat conducting sheet 16 is made of copper material with excellent thermal conductivity, which can quickly transfer heat to the feed hopper 12, thus realizing heat recovery. The heat conducting sheet 16 is fixedly connected to the feed hopper 12 by bolts. This connection method not only ensures the stability of the connection, but also facilitates the maintenance and disassembly of the device. By recycling the heat released when the melted rubber solidifies to heat the feed hopper 12, it can not only effectively utilize energy, reduce energy consumption and waste, and comply with the green and environmentally friendly production concept; it also helps to maintain the temperature of the melted rubber in the feed hopper 12, prevent it from solidifying prematurely, and ensure the continuity and stability of the production process.

[0027] Embodiment 2

[0028] See also Figure 4-5The side of the vertical plate 3 is provided with a straightening mechanism, which includes a short plate 17, which is fixedly mounted on the side of the vertical plate 3. The side of the short plate 17 is rotatably connected to a lower wheel 18 through a bearing, so that the lower wheel 18 can rotate freely to better adapt to the movement of the cable. The side of the vertical plate 3 is also provided with a groove

[0029] 19, the groove 19 not only provides installation space for other components, but also plays a certain positioning and guiding role. The inner wall of the groove 19 is fixed with a vertical rod 20 by welding, bolt connection, etc. The vertical rod 20 provides a precise track for the up and down sliding of the slider 21. The slider 21 adopts a sliding connection method matching the vertical rod 20.

[0030] For example, a dovetail groove ensures both smooth sliding and accurate positioning. The side of the slider 21 is also rotatably connected to the upper wheel 22 through bearings or the like, so that the upper wheel 22 can rotate flexibly when in contact with the cable, reducing the frictional resistance to the cable. In order to maintain the continuous pressure of the upper wheel 22 on the cable, a tension spring 23 is also sleeved on the surface of the vertical rod 20. One end of the tension spring 23 is fixedly connected to the inner wall of the groove 19 by a hook and a bolt, and the other end is fixed to the slider 21 by a similar connection method. In this way, the tension spring 23 can generate a downward pulling force, so that the slider 21 drives the upper wheel 22 to move downward, and clamps and straightens the cable together with the lower wheel 18.

[0031] Working principle: The melted rubber enters through the feed hopper 12, and then the cable is aligned with the cable entry hole 11. Then the motor 4 can drive the driving gear 5 to rotate, and the driving gear 5 can then drive the driven gear 6 to rotate, and the driven gear 6 then drives the hollow cylindrical shaft 7 to rotate, and the hollow cylindrical shaft 7 then drives the spiral blade 8 to rotate.

[0032] At this time, the molten rubber can be pushed forward by the rotation of the spiral blade 8, so that the cable can be wrapped by the molten rubber when passing through the hollow cylindrical shaft 7, and then the cable enters the molding chamber 9, and then cold water is passed into the cooling pipe 13. At this time, the cooling pipe 13 can allow the molding chamber 9 to cool down, and the molten rubber can be solidified at this time, thereby forming a finished cable. After the cold water passing through the cooling pipe 13 is heated due to heat absorption, it can enter the water tank 15 when it finally passes through the cooling pipe 13. At this time, the heat conducting plate 16 in the water tank 15 can be heated, and the heat conducting plate 16 can heat the feed hopper 12. In this way, the heat generated when the molten rubber solidifies can be recovered to heat the feed hopper 12. In this way, it can be avoided that after the feed hopper 12 is cooled, the molten rubber will be cooled down and solidified when it enters the molten rubber later. The utility model heats the feed hopper 12 by recovering the heat released when the molten rubber solidifies, which not only effectively utilizes energy, but also reduces energy consumption and waste, and conforms to the green and environmentally friendly production concept.

[0033] The heated water in the cooling pipe 13 heats the heat conducting sheet 16 in the water tank 15, thereby heating the feed hopper 12.

[0034] Not only does it recycle heat, it also helps to maintain the temperature of the molten rubber in the feed hopper 12 to prevent it from solidifying prematurely. When the cable enters the wire entry hole 11, the lower wheel 18 and the upper wheel 22 can clamp the cable. At the same time, due to the tension of the tension spring 23, the tension spring 23 can pull the slider 21 downward to move, and the slider 21 can then drive the upper wheel 22 to move downward. At this time, the upper wheel 22 can squeeze the cable, so that the cable can be straightened. The utility model can straighten the cable more effectively through the clamping effect of the lower wheel 18 and the upper wheel 22, and the slider 21 driven by the tension of the tension spring 23 to move the upper wheel 22, thereby improving the state of the cable before entering the extrusion chamber 2, and providing better prerequisites for subsequent extrusion wrapping and cooling molding. In addition, by straightening the cable when it enters the wire entry hole 11, the bending and twisting of the cable can be greatly reduced, thereby ensuring that the shape of the extruded cable is more regular and the electrical performance is more stable.

However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
