Abstract

The invention discloses a cable production cooling device in the field of cables. The cable production cooling device comprises a first water cooling unit, the first water cooling unit comprises a first water tank and a first cooling tower, a water inlet pipe of the first cooling tower is communicated with the first water tank, a heating block, a water flow control mechanism and a temperature control mechanism are arranged in the first water tank, the water flow control mechanism comprises a water control part and a first electromagnet with a negative temperature coefficient thermistor connected in series in a power loop, the water control part is connected between the first electromagnet and the water inlet pipe, the temperature control mechanism comprises a temperature control part and a second electromagnet with a positive temperature coefficient thermistor connected in series in a power loop, and the temperature control part is connected between the second electromagnet and the heating block. The problems that in an existing slow cooling technology, the temperature of a first-section water tank is not controlled, and the cooling quality of wires and cables is unstable can be solved.

Description

technical field [0001] The invention relates to the field of cable production, in particular to a cooling device for cable production. Background technique [0002] The wires and cables formed during the wire and cable production process should be cooled and shaped immediately after leaving the head of the extruder, otherwise they will be deformed under the action of gravity. The cooling method usually adopts water cooling, which can be divided into rapid cooling and slow cooling according to the water temperature. Quenching is direct cooling with cold water. Quenching is effective in shaping plastic extruded cladding, but for crystalline polymers, it is easy to retain internal stress inside the extruded cladding due to rapid cooling, resulting in cracks during the use of wires and cables. Slow cooling is to reduce the internal stress of the product. Water of different temperatures is placed in sections in the cooling water tank to gradually cool down and shape the product....
