Description

Technical Field

[0002] With the continuous expansion of the scales of industries such as the power industry, data communication industry, urban rail transit industry, automotive industry, and shipbuilding industry in China, the demand for wire and cable will also increase rapidly. In the future, the wire and cable industry still has great development potential. During the cable processing, including core manufacturing and sheath production, generally the core and the sheath are formed together through a high-temperature extruder. Therefore, after extrusion, a certain amount of cooling is required. Currently, for cooling the cable, the cable is placed in a card slot located in cooling water, and the cable is cooled by the cooling water. However, the effect of this cooling device is not ideal. Since the temperature of the cooling water will gradually increase during the long-term cable production process, its cooling effect becomes worse and worse, unable to meet the requirements of normal production, and the product quality is poor. In addition, there are also improvements made to this cooling device, adopting the method of circulating water spraying to further improve the cooling effect. However, it is still found in actual production that there are defects in the obtained products. The water directly impacting the cable itself will have an adverse effect on the cable surface. In addition, bubbles will also be generated on the cable surface during the cooling process, and the surface of the final product is rough and even pits, protrusions, etc. will occur.
