Description

Technical Field

[0001] The utility model relates to the technical field of extrusion cooling devices, in particular to an extrusion cooling device for cable processing. Background Art

[0002] Cable production requires plasticization at high temperature with the help of an extruder, and further cooling and shaping is required after extrusion. In the prior art, cooling is performed by condensed water or cooling air. For example, the patent with application number CN202010595087.7 ​​discloses a cooling device for cable processing, which is provided with a wiping device installed inside a cooling box, and uses a combination of air cooling and water cooling to cool down. Specifically, it is provided by further providing multiple first shells in the cooling box, and providing a flannel layer in the first shell for wiping;

[0003] However, since the temperature of the newly extruded cable is relatively high, if flannel is used directly for cooling, it is not only easy for the cable to burn the flannel and transform it into a hard lump, causing damage to the subsequent cables, but the upper limit of heat exchange by wiping cooling is low. Usually, after wiping a certain length of cable, the flannel and the cable are almost at the same temperature, and the heat exchange cannot keep up with the heat exchange requirements of the newly extruded high-temperature cable, and continuous and efficient cooling cannot be achieved.

[0004] Based on the above description, there is an urgent need for an extrusion cooling device for cable processing that can continuously and efficiently reduce the temperature. Utility Model Content

DETAILED DESCRIPTION

[0020] Example 1

[0021] See also Figure 1 to Figure 2The utility model provides the following technical solutions: an extrusion cooling device for cable processing, which is suitable for cooling cables after high-temperature extrusion.

[0022] Specifically, Figure 1 and Figure 2 As shown, an extrusion cooling device for cable processing includes a box body 1, a wiping component 2, a cooling pipe 3, an atomizing component 4 and a scraping component 5; the atomizing component 4 is arranged in the cooling pipe 3; the cooling pipe 3 passes through the box body 1; the cooling pipe 3 includes a first pipe section 31 and a second pipe section 32; the wiping component 2 is arranged in the second pipe section 32 and is slidably connected to the top inner wall of the box body 1 through the scraping component 5.

[0023] The specific implementation process is as follows: the extruded cable is sent into the first pipe section 31 and out of the second pipe section 32 through the cable conveying device (rollers, etc.) commonly used in the field, and the high-temperature cable just extruded is initially cooled by the atomizing component 4 (the water mist is converted into steam after heat exchange and extracted through the steam extraction pipe 13 for preheating the extrusion device); after the cable is initially cooled in the first pipe section 31, it is further cooled by wiping the cable through the wiping component 2, and the scraping component 5 cooperates with the atomizing component 4 to replace the liquid in the wiping component 2, thereby achieving an increase in the upper limit of heat exchange for continuous cooling.

[0024] In this embodiment, the wiping component 2 uses the existing commonly used high-temperature resistant memory sponge, and both ends of the wiping component 2 are connected to the inner wall of the second pipe section 32 through a connecting orifice plate 6. The connecting orifice plate 6 uses an insulating plate to reduce heat exchange interference between the pipe sections.

[0025] Specifically, Figure 2 As shown, the scraping assembly 5 includes a scraping cylinder 51 and an extension rod 52; a strip-shaped slide groove is provided at the top of the second pipe section 32; one end of the extension rod 52 is connected to the scraping cylinder 51; the other end of the extension rod 52 passes through the strip-shaped slide groove and is slidably connected to the top inner wall of the box body 1. A pair of slide rails 7 are provided inside the top of the box body 1; a slider 8 connected to the extension rod 52 is provided between the pair of slide rails 7; the slider 8 is connected to the top side wall of the box body 1 through a telescopic rod 9.

[0026] In this embodiment, the telescopic rod 9 adopts an electric telescopic rod or a hydraulic telescopic rod, etc., and the scraper cylinder 51 is driven by the extension and contraction of the extension rod 52 to scrape the liquid from the wiping component 2. The liquid is pushed out through the backflow bucket 10, and further flows back through the backflow ramp 11 to the discharge port and finally gathers at the bottom of the box body 1 and is discharged through the liquid suction pipe.
