Abstract
The invention relates to an industrial production method of a stranded earphone cord, which is characterized by comprising the following production steps: (1) doubling and extruding; a two-earphone-cord combining wire pasted by a coating layer is produced by an extrusion machine; (2) twisting: the produced combining wire is twisted by a wire twisting machine; and (3) heating setting; the twisted wire is heated and set through a high-temperature area. The earphone cords can not be dispersed from two ends after being twisted, dispersion phenomenon can not happen after segmentation, and the phenomenon of generation of a gap between the double cords at the bending part of the earphone wire can not happen, therefore, remarkable effect is achieved owning to the new process of doubling and extruding; besides, the stress of the stranded wire is eliminated after high-temperature setting, and self-winding phenomenon can not happen, therefore, the production efficiency and finished product ratio are greatly improved and the product performance is greatly improved.
Description
Technical field
The present invention relates to the earphone cord production technology, is a kind of production method of stranded earphone cord specifically.
Background technology
Common earphone cord all is a pair of bonding " 8 " font doubling mutually, in order to increase the stretching resistance of earphone cord, strengthen the aesthetic feeling of earphone cord and be convenient to take in, some earphone cord has used twisted wire, but general twisted wire technology all is to use the extruder lead of two band linings of extrusion respectively, directly stranded then, segment on request then, a tangible problem can appear in this moment, and scatter in the easy two ends of twisted wire, and when twisted wire is crooked, two lines of crooked position can separate the generation space, add the stress of the stranded generation of twisted wire, line is beaten automatically turned round, often be intertwined, be difficult to make in order, dispersion or the finished product that twines or semi-finished product can reduce production efficiency because be difficult to make in order and need manually arrange in process of production, increase percent defective, also influence the use of product.
Summary of the invention
Technical problem to be solved by this invention provides a kind of industrial process of stranded earphone cord, use this method can not occur scattering in two ends or when crooked the middle part of line occur separating the space, the automatic wrapping phenomena that self stress of twisted wire causes can not appear yet.
The industrial process of described stranded earphone cord is characterized in that: comprise following production stage:
(1), doubling extrusion: produce the earphone cord doubling that coating is bonded together by extruder;
(2), stranded: it is stranded that stranding machine is sent in the doubling of producing;
(3), add thermal finalization: stranded line is added thermal finalization through the high-temperature region.
Every line of doubling is provided with two cores or multicore metallic conductor in the described step ().
Described metallic conductor uses bare copper wire, tinned wird or enamelled wire.
The cloth of extruder uses PVC polyvinyl chloride material or TPE thermoplastic elastomer (TPE) material as the coating material in the described step ().
The adjustment of the twisting pitch size in the described step (two) realizes by changing corresponding stranding machine active and passive gear.
As a kind of prioritization scheme, realize by the hot blast that uses the energising hot hair dryer to blow out on the path of twisted wire process the high-temperature region in the described step (three).
The temperature range of the high-temperature region in the described step (three) is 50-90 degree centigrade.
After the present invention makes earphone cord stranded the phenomenon of scattering in two ends can not appear, especially the phenomenon of scattering can not appear after the segmentation, and also can not occur the phenomenon that the crooked position two-wire separate to produce the gap after the stranded earphone cord bending, reason has been to use the stranded then new technology of first doubling extrusion and the remarkable result that produces.Twisted wire has been eliminated stress through behind the high-temperature shaping in addition, not the phenomenon that can occur twining voluntarily.Such production method has significantly improved production efficiency and rate of finished products, has obviously improved the performance of product simultaneously.
Description of drawings
Fig. 1 is a schematic flow sheet of the present invention,
Fig. 2 is earphone cord structural section figure,
Fig. 3 earphone cord outline drawing.
Among the figure: 1-sizing material, 2-metallic conductor, 3-extruder, 4-doubling, 5-stranding machine, the two and twisted wire of 6-, 7-hair-dryer, the two and twisted wire of 8-typing, 9-coating.
Embodiment
Below in conjunction with the present invention is further described: the industrial process of described stranded earphone cord as shown in Figure 1, comprises following production stage:
(1), doubling extrusion: produce the earphone cord doubling 4 that coating 9 is bonded together by extruder 3;
Two, stranded: it is stranded that stranding machine 5 is sent in the doubling 4 of producing;
Three, add thermal finalization: stranded line is added thermal finalization through the high-temperature region.
As Fig. 2, every line of doubling 4 is provided with two cores or multicore metallic conductor 2 in the described step 1.
As prioritization scheme, described metallic conductor 2 uses bare copper wire, tinned wird or enamelled wire.
For bare copper wire: when using this conductor, must first extrusion heart yearn, make mutually insulated between conductor, the extrusion that is covered again, such wire rod external diameter can be bigger than normal, and flexibility is than using the poor of enamelled wire;
For tinned wire: same bare copper wire, but conductor resistance is big than bare copper wire, and this conductor is easier to welding, and corrosion resistance is strong;
For enamelled wire: need not to carry out just directly extrusion lining of heart yearn extrusion, use this conductor to do the wire rod external diameter minimum, and owing to do not carry out the heart yearn extrusion, its flexibility is best.
The sizing material 1 of institute's cloth of extruder uses PVC (polyvinyl chloride material) or TPE (thermoplastic elastomer (TPE) material) as coating 9 materials in the described step ().
Described PVC is a kind of lining body material of using always, and it is cheap, is easy to mould moulding and painted, but it is slightly poor to compare feel with TPE.And, belong to the restriction rank at present because it is halogen-containing.
Described TPE is that present earphone cord industry is used maximum lining body materials, good hand touch, and elasticity is good, and toughness is strong, and proportion also little (with PVC relatively).
The adjustment of the twisting pitch size in the described step (two) realizes by changing corresponding stranding machine 5 active and passive gears.
The tooth table of joining according to stranding machine is selected immediate lay, changes active and passive gear (equipment that has also needs to change synchromesh gear).
As prioritization scheme, realize by the hot blast that uses energising hot hair dryer 7 to blow out on the path of two and twisted wire 6 processes the high-temperature region in the described step (three).Two and twisted wire 6 has effectively been eliminated the stress of twisted wire through after adding thermal finalization, thereby makes the two also twisted wires 8 of typing the phenomenon of turning round and twining can not occur beating voluntarily.
The temperature range of the high-temperature region in the described step (three) is 50-90 degree centigrade.Temperature is determined with the distance of two also twisted wires 6, the power of hair-dryer by the translational speed of two and twisted wires 6 and hair-dryer.Hair drier 7 power of recommending to use are 1500W.
The earphone cord of producing through above step had both had aesthetic feeling, tension intensity increases, make the fine quality of the stressed increase of line, be convenient to again take in can not beat and turn round and twine, simultaneously in process of production, prevent to twine, beat and turn round and prevent the operation that two lines scatter owing to need not to increase, improved production efficiency and rate of finished products.
