Description

Technical Field

[0001] The utility model relates to the technical field of cable insulation core pair twisting, in particular to a novel lightweight wire guide wheel for a high-speed pair twisting machine. Background Art

[0002] The twisting machine is mainly composed of a pay-off system and a take-up system. It uses the double-twist working principle and is an advanced equipment that twists two insulated wire cores at high speed into a pair of wires with stable pitch by pre-twisting and then un-twisting. It mainly serves the twisting needs of high-end communication cable products.

[0003] Communication cables are mainly used to transmit data or signals, and use multiple pairs of wire cores to form multiple loops to achieve link transmission improvement. Most existing wire pulleys use alloy die-casting guide pulleys, which have been derived into various forms such as take-up pulleys, storage pulleys and meter pulleys.

[0004] The twisted wire cores are generally identified by identification numbers, which facilitates the rapid identification and installation of the equipment system. During the high-speed twisting of the insulated wire cores, the identification numbers on the surface of the wire cores are blurred or missing due to contact with the fixed ceramic rings. If they flow into the assembly process, it is easy to cause connection confusion and signal transmission errors. Utility Model Content
