When cabling producing large logarithm filling cable, adopting a compound section filling method of different temperatures, unit cabling lines are not firstly hinged or gathered, but are arranged in order, and through the corresponding dies, the unit cabling lines firstly enter into a first filling cavity to be filled with the compounds, after filling up with the compounds, the unit cabling lines are hinged or gathered, then enter into a second filling cavity to fill, air gaps between the unit cabling lines are filled with the compounds, thereby filling up the inner air gaps with the compounds tightly to ensure anti-water permeability of the filling type cable eligible. The invention can work continuously, improves production efficiency and product quality, and brings convenience for production and operation.
Description
Technical field
The invention belongs to cable process technology scope, particularly filled type communication cable compound fill method and equipment.
Background technology
At present, the water permeability resistance of most of filled type telecommunication cables can be relatively poor or defective.It mainly is because filled type cable compound is filled discontented causing.As everyone knows, filled type cable filled composite is an organic mixture at present, therefore, the flowability of compound can strengthen with the rising of temperature, but temperature exceeds certain limit, and the insulation property of compound are reduced even forfeiture, also can scald cable core simultaneously.At present, produce the compound pad device of filled type cable, be one and fill the chamber, the temperature of compound is identical during filling.When filling, if temperature is lower, compound is in half melting state like this, and mobile poor, cable inside is difficult for being full of compound; If temperature is higher, compound melts fully, good fluidity, can guarantee that compound fills up cable inside, but the space between cable conductor surface and each stranded unit is because of the mobile property of compound is good, when stranded and wrapped, cause compound loss between cable core surface and unit gap easily, thereby it is discontented to cause compound to fill.Particularly big logarithm cable effect is poorer.Therefore, when producing big logarithm filled type cable, many producers are elder generation's filled composite when producing super unit, recharges when treating total stranding, adopts the mode of twice filling, causes production efficiency low like this, wastes raw material, has increased manufacturing cost.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned background technology, and a kind of filled type communication cable compound fill method and equipment are provided.This method adopts the compound segmentation fill process of different temperatures according to filled type cable composite properties, guarantees being full of fully of compound.

The invention has the beneficial effects as follows, can work continuously, guarantee that the inside and the constituent parts of different pairs filled type cable becomes the cable gap to be full of compound, make cable water permeability resistance energy qualified.Improved production efficiency and product quality, and brought convenience for production and operation.
Description of drawings
Fig. 1 is a filled type communication cable compound pad device schematic diagram.
Embodiment
The present invention will be further described below in conjunction with Fig. 1 and embodiment.
Figure 1 shows that communication cable compound pad device schematic diagram, in the drawings, comprise two the independently first fill system A and the second fill system B, has common semi-enclosed casing 2, dividing plate by semi-enclosed casing 2 middle parts is divided into two fill systems that structure is identical, heat-barrier material is contained at the dividing plate middle part, guarantees that the composite temperature of two systems is independent of each other.Single hole mould 12 is installed on the dividing plate at semi-enclosed casing 2 middle parts, on semi-enclosed casing 2 right-hand member walls, single hole mould 12 is installed also; In fill system A, the porous mold 11 that unit becomes cable 1 to install by on the left end wall of semi-enclosed casing 2 and first filling 3 two ends, chamber, enter first and fill chamber 3, fill the compound 5 into the heat molten type petroleum jelly in the semi-enclosed casing 2, the heater 4 by bottom and sidepiece heats; The first electronic compound filling pump 6 is filled the compound 5 of complete molten state in the first filling chamber 3, stuffing pressure can show by first Pressure gauge 15 of filling 3 tops, chamber.Deceleration agitating device 9 and agitator arm 8 stir the compound 5 of complete molten state, make compound 5 temperature even, prevent petroleum jelly scald heart yearn, and keep its flowability, and thermocouple sensor 10 is used to monitor the real time temperature of compound 5.
Present embodiment is that a kind of specification is the production process of HYAT400 * 2 * 0.4 cables.
Composite temperature is 110 ℃ among the first fill system A, is in complete molten state independently among the first fill system A and the second fill system B at above-mentioned two, and composite temperature is 90 ℃ among the second fill system B, and compound is in the semi-molten state.In the production process, 4 100 pairs of units that form HYAT400 * 2 * 0.4 cable conductors become cable not gather earlier, the porous mold 11 that constituent parts becomes cable 1 to install by on the left end wall of semi-enclosed casing 2 and first filling 3 two ends, chamber enters first and fills chamber 3, fill compound 5 in the semi-enclosed casing 2, the heater 4 by bottom and sidepiece heats; The first electronic compound filling pump 6 is filled the compound 5 of filling complete molten state in the chamber 3 to first, stir the compound 5 of molten condition by deceleration agitating device 9 and agitator arm 8, make compound 5 temperature even, prevent compound scald heart yearn, and keep its flowability, thermocouple sensor 10 is used to monitor the real time temperature of compound 5, because compound is in complete molten state, mobile, penetrability is good, and constituent parts to become cable be separately to enter to fill the chamber, increased the contact area that becomes cable and compound, constituent parts becomes cable with 10 meters/min under the stuffing pressure of 0.15-0.25MPa, 20 meters/min or 30 meters/min speed are filled chamber 3 by first, guarantee that compound fills up constituent parts and becomes cable inside.Bottom and sidepiece heater can be controlled respectively, when the compound height is lower than the sidepiece heater in the casing, should close the sidepiece heater.Around the casing thermal insulation board is housed, can guarantees the temperature difference of two fill system compounds, play insulation effect simultaneously.Heating-up temperature is supervised by insertion-type thermocouple transducer 10.Can make compound in heating and filling process, guarantee that temperature is even.The structure of porous mold 11 designs according to the cable conductor arrangement architecture, and the mould aperture should directly be provided with according to cable, and is unsuitable excessive, to guarantee having enough pressure to make the solid compound of cable.
Second step, through first fill chamber 3 filled the unit of compound 5 become cable 1 through single hole mould 12 stranded be summarised in become cable conductor 14 together after, cable conductor 14 enters with 10 meters/min or 20 meters/min speed and fills chamber 13 by second in the second fill system B, by the lower semi-molten state compound 5 of the flowability of second electronic compound filling pump 7 charged pressures 0.1-0.2MPa, stuffing pressure can show control by second Pressure gauge 15 of filling 13 tops, chamber in the second filling chamber 13.Become the cable gap to fill to the constituent parts of forming filled type cable 14, filling process is the same, because composite temperature is lower among the fill system B, the state thickness can guarantee that compound fills up the constituent parts gap.Thereby guarantee that the cable water permeability resistance can pass the test.Send from the single hole mould 12 that is installed on the semi-enclosed casing 2 right-hand member walls then.
