Description
Technical field
The present invention relates to a kind of manufacturing equipment of double-colored insulated electric conductor.
Background technology
In low-voltage power system, electric power transfer generally all is three-phase four-wire system or three-phase five-wire mode, for more convenient electric wire is laid and installs, and needs A phase, B phase, C phase, the neutral line and the ground wire of electric wire are effectively distinguished.
In standard GB/T5023.1-2008; Identification has clearly regulation to the wire cable insulating core: " insulated wire cores of cable uses painted insulation or other suitable method is discerned; except that the insulated wire cores with yellow/green combined color identification, and a kind of color should be only used in each insulation of cable ".All cable manufacturing enterprises successively adopt the unit cable integral colouring according to above-mentioned request of national standard, promptly adopt this material of insulation to mix in proportion with color masterbatch, carry out painted according to the international standard colour code.Though this production technology satisfies request of national standard; But when the insulation colour changing, there is following problem: for guaranteeing the requirement of color National standard colour code; Need the color of front insulation is thoroughly cleared up: also need after the screw rod on the dismounting and cleaning extrusion equipment, head, the loading hopper screw rod, head were heated 1.5 hours at least; Just can descend the production of bar insulation line, so the labour intensity of workman's operation is big, production efficiency is low; If do not carry out dismounting and cleaning equipment, then need original material to be cleaned with the material of production color, not only waste of material is serious, and the discharge time is long especially.
Be to reduce a series of problems that the insulation colour changing brings, some manufacturing enterprise adopts vitta line to replace color masterbatch, promptly before conductor wire core gets into extruder head, adopts resistant to elevated temperatures minute colour band with the conductor wire core coating of insulating.According to said method; Though adopt color masterbatch to greatly reduce production cost than insulation; Also improved production efficiency relatively, but, be not to be looped around around the conductor wire core because the branch colour band is between conductor wire core and insulating barrier, to fill; And the coating pattern is to adopt tubular molding tool, so has the gap between conductor wire core and the insulating barrier.In addition, if divide colour band too early or too much being bonded on the insulating barrier, insulating barrier can not effectively evenly stretch, and causes partial insulative layer thick partially, or other place draws and approach or pull open, and causes product rejection, and there is certain influence in product quality; In addition,, just can be clear that colour band, increase the site operation difficulty because vitta between conductor and insulation, when cable laying is constructed, needs to separate insulation.
The production technology that also has a kind of double-colored insulated electric conductor is to utilize two extruders that the Insulation Material of two kinds of colors (or two kinds of materials) is extruded in outside the conductor wire core of electric wire simultaneously, forms two kinds of materials (or two kinds of colors) insulation half-and-half.To outer surface thickness, as long as this not only wastes color masterbatch to the insulated electric conductor that can distinguish phase sequence, and energy consumption is bigger from conductor in the insulation of two kinds of colors that this technology forms.
