Laminating hot air supply of flat cable maker {Apparatus for hot air injection of flat cable maker}

The present invention relates to a flame retardant flat cable manufacturing apparatus, and more particularly, to provide a better quality plane by supplying hot air at a predetermined temperature to a laminating portion of a plurality of rows of wires and films to make the laminating state of the wires and films more uniform. The present invention relates to a laminating hot air supply device for a flat cable maker that enables a cable to be manufactured.

With the recent development of the electronics industry, flat cables (flat cables) are commonly referred to as insulated conductors arranged side by side at regular intervals for the purpose of minimizing the mounting area and ease of handling according to the trend of compactness, precision, and harness simplification. It is called). In particular, the use of flat cables is gradually increasing in rockets, missiles, aircraft, and high-tech electronic communication equipment. However, the conventional flat cable is a product extruded with a polyester film and has a low melting point. Therefore, when a high temperature environment and fire occurs, there is a problem that serious damage to equipment and equipment. In order to solve such a problem, the need for a product laminated with TEFLON such as polytetrafluoroethylene (PTFE) having excellent flame retardancy has begun to emerge.

Thereafter, various types of flame retardant cable manufacturing techniques are known for the production of flat cables using polytetrafluoroethylene (PTFE), which is summed or coated with polytetrafluoroethylene or propylene. Unscrewed rows of wires from the wire supply rack to the liner, through a core heater consisting of a pair of upper and lower pairs to prevent any air bubbles inside the flat cable and to preheat the wires before feeding to the heating and crimping device Preheated and supplied with polytetrafluoroethylene or propylene films through IR heaters and shoe heaters, respectively, above and below the wires supplied so that the fluorinated ethylene propylene layers are bonded to each other by heat compression. The fill supplied from above and below Is laminated at a predetermined temperature by the lower heating roll and the upper heating roll, the laminated flat cable is cooled by the cooling roll, and the cooled flat cable is cut by the rotary slitter in the longitudinal direction according to the predesigned method. The film attached to both edges was cut | disconnected by the rotary slitter, and the flat cable was tensioned by the tension roll, and each flat cable was wound up by the flat cable winding roll. It is characterized by the above-mentioned.

However, according to the conventional flame retardant flat cable manufacturing technology as described above, the upper film and the lower film are combined with the wire with respect to the transport direction of the wire to produce a flat cable, the upper film and the lower film overlap Although it was previously configured to preheat the upper film and the lower film with separate IR heaters and shoe heaters, there was a disadvantage in that the upper film and the lower film could not be efficiently preheated because they are far from the laminating area. The upper and lower portions of the wire could not be laminated to the upper film and the lower film effectively to produce a good quality flat cable, there was a problem that can not perform the role of the flat cable properly.

Moreover, the laminating temperature of the upper film and the lower film and the wire becomes a very important factor in maintaining the laminating environment of the wire and the upper film and the lower film in an optimal state. In addition, according to various materials and thicknesses of the lower film, the laminating temperature could not be effectively coped, and thus, there were many difficulties in manufacturing a good quality flat cable.

An object of the present invention is to laminate the hot air of the flat cable making machine to produce a higher quality flat cable by precisely and accurately laminating the wire and the upper film and the lower film in various materials and thicknesses of the upper film and the lower film. To provide a supply.
