When the temperature sensor 6.19 detects that the temperature of the water in the water storage tank 6.3 is too high in the whole cooling process, the first cooling water pipeline delivery pump 6.16 is turned on, the cooling water is delivered to the refrigerator 6.4 from the water storage tank 6.3 for refrigeration, then the second cooling water pipeline delivery pump 6.17 is turned on, the cooling water after refrigeration is delivered back to the water storage tank 6.3 from the refrigerator 6.4 until the temperature sensor 6.19 detects that the temperature of the water in the water storage tank 6.3 meets the requirement, and the first cooling water pipeline delivery pump 6.16, the second cooling water pipeline delivery pump 6.17 and the refrigerator 6.4 stop working.
During the whole cooling process, as the cooling water flows out from the upper right water supply opening 6.18 of the first magnetic mechanism 6.25, the cooling water flowing out from the water supply opening 6.18 falls on the right impeller plate 6.257 of the first magnetic mechanism 6.25, so as to drive the first rotating shaft 6.252 to rotate clockwise, at this time, due to the change of magnetic lines of force of each magnet, the cooling water flows leftwards from the cooling area 6.6 to the feeding area 6.5 in the cooling tank 6.2 from the water discharge opening 6.10 through the water supply pipeline 6.12 to the water storage tank 6.3, then the cooling water in the water storage tank 6.3 is supplied through the water supply pipeline 6.12 and falls from the water supply opening 6.18, and the cooling water cuts the moving magnetic lines of force during the whole cooling water circulation process, so as to magnetize the cooling water, thereby improving the cooling efficiency. In addition, cooling water flows leftwards from the cooling area 6.6 to the feeding area 6.5 in the cooling groove 6.2 and flows from the water outlet 6.10, the flow direction of the cooling water is opposite to the advancing direction of the cable, so that the cable can be slowly cooled, namely the cooling water contacted with the cable is cooled by heat in the cooling process of the cable, the cable is cooled step by step, the cooling effect is better, and the extrusion molding quality is ensured.
