Description

Cable cooling device and cable manufacturing equipment

Technical Field

The utility model belongs to the technical field of cable manufacturing equipment, and particularly relates to a cable cooling device and cable manufacturing equipment.

Background

The cable generally comprises a core and an insulating coating layer coated on the outer surface of the core, and the manufacturing equipment of such cable generally comprises a coating device (extruder), a cooling device and a traction device which are arranged in sequence.

The cooling device is provided with a cooling groove and a cable guiding mechanism, cooling liquid is filled in the cooling groove, gaps for the cables to pass through are formed in the two ends of the cooling groove in the length direction, and the cable guiding mechanism comprises guide wheels arranged in the cooling groove. In the manufacturing process, the traction device continuously pulls the cable and the cable core to advance, the cable core enters the coating mold core under the guidance of the cable core guiding mechanism, the heating mechanism heats the coating material in a solid particle state to be in a molten fluid state, the coating material in a molten state is extruded into the coating mold core through the extrusion mechanism, the cable core part where the coating material is coated is formed into a cable, and then the cable enters the cooling groove through a notch on the cooling groove to be cooled, so that a final cable product is formed. Wherein a length of the wire core/cable from the wire core guiding mechanism to the distal end of the cooling trough is substantially linear.

The cables to be manufactured are generally of a plurality of different sizes, whereas in current cooling devices the cooling grooves and the guide wheels for guiding the cables are usually stationary, which results in an eccentric situation of the cable centre with respect to the centre of the covering mould core when part of the cable is carried on the guide wheels. As described above, a length of the wire core/cable from the wire core guiding mechanism to the distal end of the cooling tank is linear, so that even if the center of the upstream wire core and the center of the sheathing die core are manually aligned before the production of the cable is started, after the production of the cable is started, since the cable section downstream of the sheathing die core is eccentric with respect to the center of the sheathing die core, the cable section pulls the upstream wire core, causing the upstream wire core to be eccentric with respect to the center of the sheathing die core, thereby causing the following problems: firstly, the thickness of the coating layer is circumferentially uneven; secondly, the eccentric wire core may be abutted against the side wall of the central hole of the cladding mold core, so that the side wall is cooled, the temperature and the cooling time of cladding materials in the cladding mold core are uneven, uneven internal stress of the cable can be caused, the defects of tiny cracks and the like of the cladding layer are shown, and the quality and the service life of the cable are influenced.

The driving mechanism for cooling comprises a driving motor for cooling, a screw rod and other transmission structures and is used for driving the sliding block to move along the vertical guide rail and driving the guide wheel 242 for cooling to move up and down.

The heat retaining mechanism includes a semiconductor heater provided in the tank 221 for heating the cooling liquid in the tank 221 so as to maintain it at a certain temperature. The coated cable fed from the coating core 131 is cooled at about 300 ℃, but the temperature of the cooling liquid is not too low, and when the high-temperature cable directly enters the cooling liquid with too low temperature, the coating layer of the cable is easy to crack due to sudden temperature change. Therefore, it is necessary to keep the cooling liquid within a certain temperature range.

The detection mechanism includes a temperature sensor disposed within the tank 221 and a calliper disposed near an end of the cooling tank 220 near the cladding apparatus 100. Wherein the temperature sensor is used for detecting the temperature of the cooling liquid in the tank 221. The calliper is used to detect the diameter of the cable that is about to enter the cooling trough 220. Based on the measured temperature, the thermal insulation mechanism can be correspondingly controlled. Based on the measured diameter of the cable that is about to enter the cooling slot 220, the cooling drive mechanism may be controlled accordingly such that the cooling guide 242 is moved to a position that substantially aligns the center of the cable carried on the cooling guide 242 with the center of the overmold core 131.
