Method for placing ground wire in producing cable and device thereof

Abstract

This invention discloses earth wire placement method and device when generating cable. The method is that the wire is wound on the core, and then shielding layer is weaved or coated. The device includes support frame, directive wheel, directive wheel bracket, driving and driven wheel and belt. The driving wheel is connected to the motor, the directive wheel is set on the bracket, the driven wheel is set on the support, the belt is connected to the driving wheel, directive wheel and driven wheel, earth wire coil is set on the driven wheel axis, and wire module core idler pulley are set below the driven wheel. The earth wire parallel with the core is volute enwound on the core, so the wire reliability is enhanced, hooked heave or earth wire fracture during execution are lightened, and the cable electrical specification is improved.

Description

technical field [0001] The invention relates to cable production technology, in particular to a device for placing grounding wires during cable production. Background technique [0002] In the manufacture of data cables, symmetrical cables and other cables that require a shielding layer, in the production process of using multi-strand metal wire braiding or aluminum foil as the shielding layer, a grounding wire must be added to achieve shielding grounding and improve electrical performance. At present, in the production process of this type of cable, the grounding wire and the core wire enter in parallel, re-braid or wrap the shielding layer longitudinally. When passing the traction wheel and the guide wheel, the grounding wire will protrude, especially when the sheath layer is squeezed There will be small bumps on the surface; in this way, when the cable is bent during construction, the cable sheath will have a hook-like protrusion or the grounding wire will break, which wi...

At present, in the production process of this type of cable, the grounding wire and the core wire enter in parallel, re-braid or wrap the shielding layer longitudinally. When passing the traction wheel and the guide wheel, the grounding wire will protrude, especially when the sheath layer is squeezed There will be small bumps on the surface; in this way, when the cable is bent during construction, the cable sheath will have a hook-like protrusion or the grounding wire will break, which will affect the use of the cable.
