Cable sheath adhesive force control device

Abstract

A cable sheath adhesive force control device, which belongs to the field of wire and cable processing facilities, comprises a base plate on which an oil recycling barrel is arranged, a support pillar fixed on the base, an oil supply container fixed on the upper part of the support pillar, an oil absorbent felt oil absorption control mechanism fixed on an oil absorbent felt slot, an oil supply mechanism, and a redundant oil recycling pipe, wherein an inlet is formed on the top of the oil supply container, and an outlet extends from the bottom; the oil absorbent felt slot is fixed on the support pillar; a pair of oil absorbent felts are arranged in the cavity of the oil absorbent felt slot; a conductor inlet is formed on the wall body on one side of the oil absorbent felt slot, and a conductor outlet is formed on the wall body on the other side; the oil supply mechanism is connected with the outlet and communicated with the cavity of the oil absorbent felt slot; and one end of the redundant oil recycling pipe is in matched connection with the bottom wall of the cavity of the oil absorbent felt slot, and the other end extends into the oil recycling barrel. The cable sheath adhesive force control device provided by the invention has the advantages that the device can meet the technological requirement on adhesive force between the sheath and the conductor without causing waste and pollution, and is simple in structure and convenient to manufacture and use.

Description

technical field [0001] The invention belongs to the technical field of wire and cable processing facilities, and in particular relates to a cable sheath adhesion control device, which is used to apply oil to the surface of a cable conductor to control the adhesion between the cable sheath and the conductor. Background technique [0002] With the continuous enhancement of human awareness of environmental protection, cables (cables are short for wires and cables, the same below) insulation materials, especially sheath materials, have been changed from the previous PVC (PVC: polyvinyl chloride) to environmentally friendly low-smoke and non-toxic Halogen materials, low-smoke and halogen-free materials such as low-smoke and halogen-free polyolefins, irradiation cross-linked PE (PE: polyethylene) used in photovoltaic cables, etc., these materials have ideal environmental protection, oil resistance, wear resistance and weather resistance . However, during the extrusion process, t...

AI Technical Summary

Problems solved by technology

However, during the extrusion process, that is, the process of extruding the sheath outside the conductor, due to the high viscosity of the material and changes during the cross-linking process, the adhesion between the insulating sheath and the conductor is relatively large. So the following technical problems arise: first, due to the unavoidable twisting of the cable during use after construction and laying, there are potential accidents such as cable short circuit, open circuit, and even fire; It cannot slide relative to the conductor, so it is easy to be stretched and damage the insulating sheath, and the friction between the sheath and the conductor will also damage the sheath when stretched

However, these two patented technical solutions also have no reference significance for dipping oil-based release agents on the surface of conductors.
