A sheath production device for longitudinally wrapping welding and forming of cable strips

Abstract

The invention relates to the technical field of cable sheath production. The invention provides a sheath production device for cable strips that are longitudinally wrapped and welded, including a production frame, a longitudinally wrapped module and an extrusion device. The cable core is formed from the The inside of the production frame passes through, and the longitudinal wrapping module is installed inside the production frame. The longitudinal wrapping module includes a coating wheel, a first installation wheel, a reduction shaft, a strip drum, and a first drive motor , the second drive motor and the first transmission wheel, the coating wheel is a hollow gear, the coating wheel is movably connected with the first installation wheel through a hollow bearing, and the reduction shaft is arranged on the coating wheel And it is connected with the output end of the first drive motor, a sheath strip is wound on the outside of the strip tube, the strip tube is sleeved on the reduction shaft, and the first transmission wheel drives the package The membrane wheel rotates, and the coating wheel rotates to wrap the sheath strip on the cable core. The invention can produce a sheath with uniform size, and the effect is stable.

Description

technical field [0001] The invention relates to the technical field of cable sheath production, in particular to a sheath production device for longitudinally wrapping and welding strips for cables. Background technique [0002] The cable sheath is the outermost protective sheath of the cable. The material of the sheath is generally black high-density polyethylene material with excellent insulation. The special high-density polyethylene base resin for the sheath material is selected, and high-quality carbon black masterbatch and other related materials are added. Processing aid, made by mixing and granulating. High-quality carbon black masterbatch content, carbon black particle size, dispersion and other factors have a great impact on the long-term performance of optical cables such as ultraviolet radiation aging resistance and heat aging resistance. The common sheath material is generally PVC, and the traditional digital cable sheath production The method is to heat the pv...

Problems solved by technology

High-quality carbon black masterbatch content, carbon black particle size, dispersion and other factors have a great impact on the long-term performance of optical cables such as ultraviolet radiation aging resistance and heat aging resistance. The common sheath material is generally PVC, and the traditional digital cable sheath production The method is to heat the pvc material into glue, and then extrude and coat it on the surface of the digital cable to form it. There may be a phenomenon that the sheath is not uniformly extruded, resulting in a certain deviation in the product structure and size.
