Description

TECHNICAL FIELD

[0001] The utility model relates to cable production technical field, concretely is a kind of spraying cooling device for covering continuous extrusion processing. BACKGROUND

[0002] Covering extrusion is an important link in the production process of wire and cable, mainly used for covering insulation layer or other protective layer outside the conductor. In the continuous extrusion process, the temperature of the skin is relatively high, and if cooling is not carried out, it will cause the skin material to overheat and decompose. In addition, cooling can also make the surface of the molten extruded cable skin solidify and stabilize, prevent the material from falling and deforming under the influence of its own gravity, ensure the uniform thickness of the insulation layer or sheath layer of the cable, and avoid product unqualified.

[0003] The cooling device for cable covering continuous extrusion processing in the prior art is mostly immersed in the water tank and passed through the water tank. The temperature of the water in the water tank rises due to the heat of the covered cable. Since there is no cooling measure, the subsequent cable cannot be effectively cooled. Therefore, we propose a spraying cooling device for covering continuous extrusion processing. UTILITY MODEL CONTENTS

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a spraying cooling device for covering continuous extrusion processing. The device has a reliable surrounding spraying unit. The covered cable passes through the inside of the cavity sleeve shaft, passes through the middle of the rotating frame horizontally and passes out from the cavity sleeve shaft on the other side. When the rotating frame rotates, it can drive the water spray head installed on the inside to spray the covered cable, so that the skin covering the outside of the cable can be uniformly cooled. The spraying method can always ensure that the covered cable is cooled with water at a relatively low temperature, thereby greatly improving the cooling efficiency of the covered cable. The device also has a reliable water recycling unit that can recycle and cool the water used for spraying and use it as part of the water source supply, reducing the waste of water resources. The connector can supply water while maintaining the rotating effect of the cavity sleeve shaft, ensuring the effective supply of spraying water, and effectively solving the problems in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a spraying cooling device for covering continuous extrusion processing, comprising a horizontal water tank, a surrounding spraying unit and a water recycling unit.
