Cooling water flow controllable cable water cooling device

Abstract

The present invention relates to the technical field of cable production, especially to a cooling water flow controllable cable water cooling device. The device comprises a water tank, one end of thewater tank is provided with a guide tube communicating with the water tank, the head end of the guide tube is a conical surface, the small end of the conical surface is close to the water tank, one incoming line conical base is inserted into the head end of the guide tube, the conical surface of the incoming line conical base and the conical surface of the guide tube are cooperated to form an annular water guide groove with taper degrees, the head end of the guide tube is provided with a water inlet tube communicating with the annular water guide groove; the incoming line conical base is provided with a through hole configured to allow a cable to be cooled to pass through, and the cable to be cooled is accessed from the through hole and enters the water tank through the guide tube. The flow speed of the through hole is low so that it is not easy to cause impact on the cable to influence appearance and water flowing out of the through hole is not sprayed on an extruding machine head tocause damaging, water absorption materials are not needed to be installed in the water tank for water blocking so as to save the water absorption materials such as wool felt and so as not to generatepollution of the cooling water.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a cable water cooling device with controllable cooling water flow. Background technique [0002] In the current cable production process, it involves high-temperature extrusion of metal conductors to form an insulating layer. After high-temperature extrusion, in order to make the insulating layer solidify and form as soon as possible, the extruded cable needs to be cooled and formed. In the current traditional technology, in order to realize the cooling and forming of the cable, the cable is generally entered into the water tank from the opening of the water tank after being extruded from the head of the extruder for water cooling and cooling to shape. On the one hand, the aperture of the opening is generally larger than the diameter of the cable, so when the cable to be cooled is sent into the water tank, part of the cooling water inside the water tank will also flow ou...

AI Technical Summary

Problems solved by technology

On the one hand, the aperture of the opening is generally larger than the diameter of the cable, so when the cable to be cooled is sent into the water tank, part of the cooling water inside the water tank will also flow out from the opening, and when the water level in the water tank is high, the opening will be caused. The water pressure at the opening is too high, and the cooling water is sprayed out from the opening, which is easy to spray into the extruder and cause damage; in order to prevent the cooling water from spraying out from the opening, the practice of clamping wool felt and other super absorbent materials at the opening was adopted. , and the insulation layer of the cable that has just completed the high-temperature extrusion step is not completely cured, which will inevitably pollute the wool felt and water quality, and the wool felt needs to be replaced regularly
