Description

Powder coating device for cable processing

Technical Field

The invention relates to the field of cable processing, in particular to a powder coating device for cable processing.

Background

In the manufacturing process of the power cable, the phenomena of glue and adhesion are easy to occur between the insulated wire core and the outer sheath, and particularly the phenomena of sticking and adhesion are easy to occur when the outer sheath is extruded outside the insulated wire core or the stranded conductor through an extruder. The adhesive and the adhesion not only seriously affect the flexibility of the cable, but also affect the subsequent processing and laying installation of the cable, and can also cause the peeling difficulty of the cable, and more seriously, the adhesive and the adhesion can even cause the tearing of the insulating layer when the cable is bent, thereby reducing the service life of the cable and causing safety hazard. The cable isolating agent is usually prepared by coating isolating powder on an insulated wire core in the industry so as to facilitate the separation of the wire core and a sheath, the existing isolating powder coating step is usually realized by adopting a powder coating device, the powder coating device comprises a powder box filled with the isolating powder, a wire rod needing to be coated with the powder directly penetrates into one end of the powder box through the traction action of an extruder and then penetrates out of the other end of the powder box, and a layer of isolating powder is attached to the surface of the wire rod. But because the isolation powder has certain adhesion and solid plasticity, after the powder is kept apart to the insulating sinle silk, can form a cavity that is taken out by the insulating sinle silk in the isolation powder, the cavity can collapse down under the action of gravity for subsequent sinle silk still can coat the isolation powder, the isolation powder that causes the insulating sinle silk to be infected with is inhomogeneous etc. and scribbles whitewashed phenomenon that the effect is not good, when gluing too much isolation powder on the insulating sinle silk, not only extravagant material, and when it got into the extruder, can cause phenomena such as line face package, seriously influence power cable's outward appearance, quality, reduce its result of use and life.
