A device and method for merging cable core wires

Abstract

The invention discloses an apparatus and a method for combining cable core wires, belongs to the field of cable production field, and solves the problems of inconsistent loosening degree of core wire winding or even wire breaking due to external tension changes easily caused when the existing core wires are combined to a core wire reel. The apparatus comprises a wire-combining unit, wherein the wire-combining unit comprises a balance adjustment unit, a balance connecting rod and a tensioning unit; the balance adjustment unit comprises an adjusting box body, an upper pressing wheel and a pressing rod; the tensioning unit comprises a tensioning wheel; the tensioning wheel is provided with a tensioning belt; one end of the tensioning belt is fixed on the base while the other end of the tensioning belt is fixedly connected with the balance connecting rod; the upper pressing wheel is an eccentric wheel, and is arranged at the upper end of the box body through a pin shaft; the pressing rod is arranged at the middle end of the adjusting box body through the pin shaft; the tail end of the pressing rod is in contact with the upper pressing wheel; and the balance connecting rod is hinged with the tail end of the pressing rod. According to the apparus, the magnitude of the tension in the transmission process of the core wires can be automatically balanced, so that the consistent loosening degree of the core wire winding can be ensured, and the phenomenon of core wire breaking is further avoided.

Description

technical field [0001] The invention belongs to the field of cable production equipment, and in particular relates to a device and method for merging cable core wires. Background technique [0002] The cable includes a cable core and an insulating coating wrapped around the cable core. The structure of the cable core includes many kinds, some are twisted by several or several groups of wires (at least two in each group), each group of wires is insulated from each other, and often twisted around a center; It is formed by directly twisting multiple cable core wires, and its structure is similar to that of a rope. The latter kind of cable core needs to wind each cable core wire to the same core wire reel before stranding, and the number of cable core wires on each core wire reel is six or eight. In order to make such a core wire reel, A dedicated doubling device is required. [0003] Chinese patent application number 200910212690.6, a patent document published on June 9, 201...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that the existing cable core wires are easily affected by changes in external tension when the core wires are merged into the core wire coil, resulting in inconsistent coiling or even broken wires, the present invention provides a device and method for merging cable core wires, which can automatically balance the core wires. The tension during the wire transmission process ensures that the core wire is coiled tightly and tightly, and avoids the phenomenon of core wire breakage
