Description

Technical Field

[0001] The utility model belongs to the technical field of network cable production, and particularly relates to a twisting device for six types of network cables. Background Art

[0002] Category 6 network cable (CAT6) is a type of network cable, that is, a cable that meets the CAT-6 standard. The transmission rate is 1000Mbps. Category 6 network cable uses 23AWG single-core bare copper as the conductor, polyethylene polymer material as the insulator, and flame-retardant polymer material as the outer sheath material, and the color is gray.

[0003] For example, the patent with application number CN201822137871.4 discloses a CMP-grade CAT6UTP network cable, including a cross skeleton, a twisted pair and a flame retardant layer. The cross skeleton is provided with a twisted pair, and the twisted pair also includes a wire core, an HDPE layer and an FEP layer. The outer side of the wire core is coated with a HDPE layer, the outer side of the HDPE layer is coated with a FEP layer, and the outer side of the cross skeleton is coated with a flame retardant layer.

[0004] For example, the patent with application number CN202023273420.7 discloses a double-shielded network cable, including an outer sheath, a first shielding layer, a second shielding layer, four pairs of twisted pair wires and a cross skeleton; the outer sheath, the first shielding layer and the second shielding layer constitute a containment protection structure, and the containment protection structure has a containment space, and the containment protection structure wraps the four pairs of twisted pair wires and the cross skeleton in the containment space; the outer sheath wraps the first shielding layer, and the first shielding layer wraps the second shielding layer; the four pairs of twisted pair wires are respectively twisted orange and white wires and orange wires, green and white wires and green wires, blue and white wires and blue wires, and brown and white wires and brown wires; the cross skeleton includes four partition walls, and the cross skeleton divides the containment space into four parts, and the four pairs of twisted pair wires are respectively arranged in the four parts of the containment space; the thickness of the two partition walls close to the twisted pair wires twisted with the green and white wires is greater than the thickness of the other two partition walls.

[0005] For example, the patent with application number CN202221939469.8 discloses a category 6 network cable with good high temperature resistance, including a protective cover, an insulating layer fixedly connected to the inside of the protective cover, a cross frame installed inside the insulating layer, a wire core fixedly connected to the surface of the cross frame, a shielding layer fixedly connected to the surface of the wire core, and a high temperature resistant layer fixedly connected to the surface of the protective cover.

[0006] The preparation process of Category 6 network cables is to extrude an insulation layer on the copper wire, twist it into a twisted pair, twist four twisted pairs of wires with a cross frame to get a cable core, and then wrap the cable core with an insulation layer and a sheath. Spark detection can be performed during the process of extruding the insulation layer on the copper wire to prevent damage to the insulation layer.

[0007] The patent with the application number CN202310664043.9 discloses a method for manufacturing a cable, which is based on a cable manufacturing device. The cable manufacturing device includes a cable production mechanism, a cable detection mechanism, and a cable winding mechanism. The cable manufacturing method includes the following steps: The cable production mechanism first draws a metal core, then twists the core, and then makes an insulating layer for the core; The cable detection mechanism detects the cable wrapped with the insulating layer to eliminate the cables with defective points; The cable winding mechanism winds and bundles the cables that have been detected and do not contain defective points.

[0008] The patent with the application number CN201520358863.6 discloses a high-speed extrusion molding device for a core, which includes a wire pay-off machine, a whole-process control box, and a double-shaft wire take-up machine. The whole-process control box includes a movable water tank and a PLC control device. One end of the whole-process control box is connected to the wire pay-off machine, and the other end is connected to the double-shaft wire take-up machine. A tension frame, a straightening table, and an extruder are sequentially arranged between the wire pay-off machine and the whole-process control box. The extruder includes an extrusion main machine, a drying hopper is arranged on the extrusion main machine, and an automatic filler is arranged on the drying hopper. A diameter measuring instrument and an automatic wire storage machine are sequentially arranged between the whole-process control box and the double-shaft wire take-up machine. A wire take-up control box is arranged on the double-shaft wire take-up machine, and a PLC control device is arranged on the wire take-up control box. The automatic wire storage machine includes a fixed water tank, a wire taking machine, and a length measuring instrument. A high-frequency spark machine and a barrel dropping device are arranged on the wire taking machine.

[0009] Although spark detection has been carried out before the preparation of twisted pairs in the prior art, according to customer feedback, the insulating layer of the twisted pairs in the network cable (qualified in spark detection during preparation) is occasionally still damaged. After analysis and investigation by the applicant, it is found that there is also a risk of damage to the twisted pairs during the processes of transportation (after being wound into a roll) or traction (such as abnormal tension adjustment and the cable dropping to the ground), resulting in unqualified products.
