Description

Technical Field

[0001] The utility model relates to the technical field of cable extruders, in particular to a cooling mechanism of a cable extruder. Background Art

[0002] A cable extruder is a device used to produce cables and wires. It is mainly used to extrude plastic or rubber materials to cover the outside of a conductor (such as copper wire or aluminum wire) to form the insulation layer and sheath of the cable. The working principle of the cable extruder is to melt the raw plastic through heating and extrusion, and then extrude it through a mold. After the cable is formed, a cooling device needs to be used to align it for cooling and solidification.

[0003] Existing cooling devices all use cooling pools to immerse and cool the formed cables. Although this can achieve a good cooling effect, moisture is likely to remain on the cable surface after cooling. If the moisture is not treated, it is easy to affect the next step of cable packaging or processing. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a cooling mechanism for a cable extruder, which has the advantage of facilitating the removal of moisture from the surface of the cable. It solves the problem that the existing cooling devices all use a cooling pool to immerse and cool the formed cables. Although a good cooling effect can be achieved, moisture is likely to remain on the surface of the cable after cooling. If the moisture is not treated, it is easy to affect the next step of packaging or processing of the cable.

[0005] To achieve the above object, the present invention provides the following technical solution: a cooling mechanism for a cable extruder, comprising a cooling pool, a drying box fixedly mounted on the outer surface of the cooling pool, and a moisture removal mechanism provided in the drying box;

[0006] The moisture removal mechanism includes an installation box fixedly installed on the lower surface of the drying box, a vacuum pump fixedly installed inside the installation box, an air inlet end of the vacuum pump passes through the drying box and is fixedly installed with a cross pipe, a plurality of first connecting pipes are fixedly installed on the surface of the cross pipe, a grid plate is fixedly installed inside the first connecting pipe, a heating rod and a sponge rod are fixedly installed on the surface of the grid plate, a second connecting pipe is threadedly connected to the top of the first connecting pipe, a hollow ring connected to the inner cavity of the second connecting pipe is fixedly installed on the top of the second connecting pipe, a circular hole is opened on the inner surface of the hollow ring, and a rubber scraper ring and a sponge water absorption ring are fixedly installed on the inner surface of the hollow ring.

[0007] Furthermore, two first guide rollers and two second guide rollers are rotatably installed on the inner surface of the cooling pool, the two second guide rollers are located between the two first guide rollers, and the height of the first guide roller is higher than that of the second guide roller.

[0008] Furthermore, the inner cavity of the drying box is communicated with the inner cavity of the cooling pool, and a rectangular hole is opened on the surface of the drying box away from the cooling pool.

[0009] Furthermore, a threaded collar is fixedly installed on the top of the first connecting pipe, and a threaded connecting ring matched with the threaded collar is fixedly installed on the bottom of the second connecting pipe.

[0010] Furthermore, a maintenance port is provided on the upper surface of the drying box, and a sealing door adapted to the maintenance port is rotatably mounted on the upper surface of the drying box.

[0011] Furthermore, there are multiple circular holes, which are evenly distributed on the inner surface of the hollow ring. The circular holes are located between the surfaces of the rubber wiper ring and the sponge water absorption ring on opposite sides.

[0012] Furthermore, a drain valve is fixedly installed on the surface of the cooling pool away from the drying box, and the drain valve is connected to the cooling pool.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] The cooling mechanism of the cable extruder is provided with a drying box on the outer surface of the cooling pool, and a moisture removal mechanism is provided in the drying box. When in use, the cable can be cooled by injecting cooling water into the cooling pool, and the moisture on the surface of the cable is removed by the moisture removal mechanism, so that the surface of the cable can be kept dry after cooling, which is convenient for the next processing and treatment of the cable. This solves the problem that the existing cooling devices all use the cooling pool to immerse the formed cable for cooling, and although a good cooling effect can be achieved, moisture is likely to remain on the surface of the cable after cooling. If the moisture is not treated, it is easy to affect the next packaging or processing of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A threaded collar 18 is fixedly installed on the top of the first connecting tube 6, and a threaded connecting ring 19 adapted to the threaded collar 18 is fixedly installed on the bottom of the second connecting tube 10, which facilitates connecting the first connecting tube 6 and the second connecting tube 10 together, facilitating disassembly of the second connecting tube 10, and facilitating replacement of the sponge rod 9 in the first connecting tube 6.

[0025] It should be noted that, after the sponge rod 9 is installed in the first connecting tube 6 , the heating rod 8 is inserted into the inside of the sponge rod 9 .

[0026] The working principle of the above embodiment is:

[0027] During use, the cable is passed under the first guide roller 15 and the second guide roller 16, and the cable is immersed in the water inside the cooling pool 1 through the second guide roller 16, and then the cable is sent into the drying box 2, so that the cable passes through the hollow ring 11 from the side close to the rubber scraper ring 13 and contacts the sponge water absorption ring 14. During the movement of the cable, the rubber scraper ring 13 will scrape off more water on the surface of the cable, start the vacuum pump 4, and vacuum the inside of the cross tube 5 through the vacuum pump 4, thereby vacuuming the inside of the first connecting tube 6 and the second connecting tube 10.
