Description

Technical Field

[0001] The present application relates to the technical field of cable processing, and more specifically, to a cable oiling machine. Background Art

[0002] Cable release agent (also known as silicone oil) is a high-performance emulsion release agent made of SILICON as the main body and finely ground by special emulsification reaction. It is non-toxic, tasteless and non-irritating. Using release agent instead of traditional talcum powder can effectively prevent the power core wire and the outer skin of the wire from sticking together, facilitate the peeling of the wire, improve the insulation effect of the wire and cable, and also increase the service life of the wire and cable.

[0003] In the related art, the core wire of the cable is generally oiled by manually holding a rag. This method has low production efficiency and high labor intensity, and is not conducive to the automation of cable processing. Currently, an oiling machine has also appeared on the market, which includes a drum with a number of steel balls soaked in silicone oil installed inside the drum. The drum is rotated by a driving mechanism, and the cable core passes through the inside of the drum and is pulled to move. The steel balls in the drum contact the core through rotation to achieve oiling of the core. Since the core is usually formed by cross-winding multiple single wires, the steel balls are large in size and difficult to contact the contact points between the single wires, so there is a defect of uneven oiling. Utility Model Content
