Description
Technical field
It the utility model is related to extrusion equipment field.
Background technology
Cable typically wraps up conductive cable core by the protective case to insulate and formed.In general production process is：Producing
Conductive cable core is placed on draw drum in journey, under the traction of hauling machine, at the die orifice of extruder, at 200 DEG C
Under the conditions of parcel one layer insulation protective case, then directly allow high temperature insulation protective jacket enter normal temperature bosh in.
The skin temperature rapid drawdown of insulation protective jacket during this, and the internal layer of insulation protective jacket is not easy to cool down, this be easy for due to
The top layer of insulation protective jacket and the temperature difference of internal layer produce internal stress very much greatly.Particularly polyethylene, TPO crystalline polymeric
Insulation protective jacket made of the materials such as thing is particularly susceptible to the influence of this internal stress.This internal stress can cause product tortoise
Split, thermal contraction performance it is bad, so as to reduce product quality.
And in large scale cable (extra-high-tension cable) extrusion, particularly PE jacketed cables are extruded, and cable surface is normal
There is fish-eye shaped puddle.Puddle Producing reason is due to that the temperature of PE extrusions is higher, and about at 200 DEG C or so, cooling water is only
There are 30 DEG C or so, sheath enters water suddenly to produce water vapour in cable surface, and the water vapour on cable top steeps upward emersion, electricity
The water vapour bubble of cable bottom but stays in cable bottom.Contacted due to the cable surface temperature directly contacted with water and with water vapour bubble
Cable surface temperature it is inconsistent, then the contraction speed of sheath is inconsistent, forms fish-eye shaped puddle, also reduces the matter of product
Amount.
Utility model content
The utility model is intended to provide a kind of cable segmented cooling device, with during large scale cable is produced,
Avoid the insulation protection of cable from being cracked during being enclosed on cooling because the temperature difference is too big, while avoid the formation of puddle.
Cable segmented cooling device in this programme, including support frame, support frame is cylindrical, support frame interior edge axis
Direction is provided with some guide rollers, is parallel to each other between guide roller, and guide roller is rotatably connected on support frame, on support frame inwall
The conduit of some annulars is provided with, conduit is concentric with support frame, and conduit is opened between two guide rollers in the circumference of conduit
There are some spray orifices, for spray orifice towards the center of circle of the conduit of annular, support frame is provided with water pipe, and water pipe is provided with quantity and conduit number
Corresponding connecting tube is measured, connecting tube connects after running through support frame with conduit, and connecting tube connects with water pipe, is set in every connecting tube
There is the heater of an adjustable heating-up temperature.
The technical principle of this programme and have the beneficial effect that：Whole device is arranged at the die orifice of extruder, and cable is from extrusion
Enter in support frame after machine extrusion, under the support and guide effect of guide roller, constantly extend into support frame.Passed through in cable
During crossing support frame, cooling water is passed through into water pipe, and starts heater and the cooling water in every connecting tube is carried out
Heating, adjust the heating-up temperature of heater so that the water temperature in connecting tube is in the range of 200 DEG C -30 DEG C along the crowded of cable
Outgoing direction successively decreases successively.Cooling water sprays to cable after heating devices heat, through supravasal spray orifice from the surrounding of cable
The surface of insulation protective jacket, and then cable is cooled down.
During cooled, cable is cooled down cable by the cooling water piecewise that jet pipe everywhere sprays, and
Because water temperature gradually reduces, avoid cable insulation protection be enclosed on cooling during there is the too big situation of the temperature difference,
Then avoid that the insulation protective jacket of cable is cracked the occurrence of；And because cooling water from the surrounding of cable sprays to electricity
Cable, the souring of 360 ° of the formation to the insulation protective jacket of cable, the vapor bubble that cable surface is formed wash away immediately,
And then avoid the formation of puddle.
Further, rotatable shower nozzle, home position of the shower nozzle towards the conduit of annular are installed on the spray orifice.Pass through
Cable surface of the shower nozzle into cooling allows shower nozzle to rotate while spraying cooling water, cooling water current is spirally sprayed to cable meter
Face, strengthens the souring of cooling water, further avoids cable surface from forming bubble.
Further, extrusion direction of the support frame as described above along cable is set diagonally downward.One is easy for work of the cable in gravity
Fallen under by a guide roller on next guide roller, be easy to cable to transmit on a guide；Two are easy for cooling water to remote
From direction convergence, the discharge of extruder, it is easy to the collection and recycling of cooling water.
Further, cooling bay is provided with below support frame as described above least significant end, water pump, water pump and water are installed in cooling bay
Pipe connects.Cooling water is flowed into cooling bay after being flowed out out of support frame and cooled down, and is pumped into again by water pump again after cooling
Into water pipe, recycling for cooling water is realized.
Further, the temperature difference between the heating-up temperature set in the two neighboring heater is not more than 40 DEG C.Avoid
The excessive temperature differentials of the cooling water sprayed in adjacent two conduits and cause the insulation protective jacket of cable to be cracked.
Further, the heater is temperature control heating rod, and temperature control heating rod is stretched into the connecting tube.Temperature control heating rod
For linear pattern, it is easy to be placed coaxially in linear connecting tube, also allows for setting heating-up temperature.
