Description

High speed electric wire extruding production line

Technical field

The utility model relates to a kind of electric wire and is produced into complete equipment, particularly relates to a kind of extruding production line of plastic insulated wire cord cable.

Background technology

Electric wire is the indispensable basic equipment such as delivery of electrical energy, information transmission, plastic insulation cable is the series products be wherein most widely used, this type of cable ties up to the coated one deck plastics of the conductive line surfaces such as copper, aluminium and forms, its complex process, change many, and production procedure is longer, the equipment adopted has very large impact to the quality of produced cable, output.Along with the internationalization of electric wire produce market, market competition is very fierce, and wires and cables industry is also increasing to the demand of high-speed high-quality wire and cable product line.

The speed of production of current wire and cable product line is mostly about 500 ms/min, minority production line can reach about 800 ms/min, but its stability need to improve, affect line speed to improve and be present in links in production line with stay-in-grade factor, in the unwrapping wire stage, usual drum is arranged on drum bolster, to drum rotating support on drum bolster, the wire warp under haulage gear effect be wound on drum is extracted out from drum to drum cylindrical, to drum along with unwrapping wire process ceaselessly rotates under the drive of wire, linear speed is higher, its rotating speed is also higher, be bearing on drum bolster to drum by rolling bearing, production requirement can be adapted under common speed of production, along with the raising of speed of production, although be supported by bearing, also there is considerable influence to block bearing in drum rotation process to the damping action of producing to drum, inertia owing to having to drum between this, the resistance produced wire is also high, cause the inequality of wire tension, payingoff speed cannot improve, in unwrapping wire process, wire is extracted out and is beaten and gets rid of inner wall of barrel at unwrapping wire from drum, the conventional staving that gets rid of is that corrosion resistant plate is made, wire to be beaten when getting rid of on staving especially as beaten a drum, bucket wall vibrations and send larger noise, linear speed is higher, and noise is larger, when usually reaching the payingoff speed of about 800 ms/min, level of noise will exceed standard, and thus also just limits the raising of speed, wire is from getting rid of after barrel paying out machine draws, can through the tensioner utilizing magnetic powder cluth to realize constant tensile control, to ensure the stability that wire runs in encapsulation process and whole subsequent production process, magnetic powder cluth can by regulating wire tension to the regulation and control of guide roller driving torque easily, but when high-speed cruising, due to the impact of the factors such as centrifugal force increasing, guide roller can change the frictional force of wire, Movement transmit stability there will be exception, thus make wire tension occur change, considerable influence is produced to the quality of production, limit the raising of speed of production, in lettering operation, lettering difficult quality guarantee under high-speed production condition, usually there will be lettering content definition not high, the phenomenon such as to bite, this has become the bottleneck of high-speed cable production line, analyze its reason and relate to lettering pressure, the aspects such as the synchronism of type wheel and cable and ink supply, lettering pressure transient not only can cause lettering color heavy or light, even produce phenomenon of biting, also can cause the change of frictional force between type wheel and cable, make to move between type wheel and cable asynchronous, cause lettering smudgy, and type wheel relies on the frictional force between cable to operate, under high-speed case, particularly in the stage of device start and stopping, make the difference between type wheel linear resonance surface velocity and cable wire speed particularly evident due to the effect of type wheel inertia, lettering quality is difficult to ensure, in ink supply side, ink retrogradation is made because the solvent in oil ink in use can volatilize gradually, the viscosity differences of ink can cause the change of lettering quality, these all significantly limit the raising of cable speed of production, in order to obtain satisfied lettering effect when cable high-speed mobile, before lettering, the encapsulate layer of cable needs to keep certain temperature and elasticity, thus still need to carry out further fully cooling to cable after lettering, in conventional cooling revolution case after lettering operation, cooling water medium motion is often driven in the motion process of wire between two groups of guide wheels after multi-turn revolution, cooling water also can produce very large resistance to the wire of high-speed cruising simultaneously, thus affects the raising of speed of production, on the other hand, wire runs under the guiding of guide wheel, in order to shorten the length of production line, in cooling device, wire is reciprocating rotating comparatively multi-turn in guide wheel group, in the hope of obtaining better cooling effect, but so, guide wheel is driven by cable and to carry out high speed rotating with the linear resonance surface velocity identical with cable speed, the guide wheel of high speed rotating certainly leads to larger running resistance, and velocity of rotation is higher, suffered resistance is also larger, resistance suffered by guide wheel is mainly from two aspects, one is the resistance of the water suffered in cooling water medium of guide wheel, two is resistances that guide wheel block bearing produces guide wheel, the resistance that the resistance of wire and the coolant suffered by guide wheel adds the block bearing suffered by upper block causes wire tension in production process to increase, required tractive effort rises, and then cause wire diameter control difficulty to strengthen, quality is unstable, normally carrying out of cable high-speed production cannot be ensured, in cable dry run thereafter, conventional drying mode is be provided with special to blow hydrophone in drying device, cable from the endoporus blowing hydrophone through time dried up by the moisture content of compressed air by cable surface.Along with the raising of cable speed of production, require that cooling and dry run can adapt with it, complete in the short period of time, this just requires that the dry run in equipment work has higher efficiency, existing drying device can make cable surface moisture content dry up on low speed production line, but for high-speed production, this cannot adapt to.

As previously mentioned, the most high energy of speed of production of current electric wire production line reaches 800 ms/min, but this can not meet the need of market, the production line that can have more speed is expected in market, its stable speed of production can reach 1200 ms/min to 1500 ms/min, and above-mentioned analyzed to affect that line speed improves with stay-in-grade factor be all expect the cable more high production speed new problem that must solve.
