Technical Field

[0001] The utility model relates to the technical field of cable core anti-oxidation, in particular to a device for coating the surface of the cable core with an antioxidant after the cable copper wire is drawn. Background Art

[0002] In the process of wire core production, the copper rod needs to be drawn step by step to form the copper wire of the required diameter. During the drawing process, due to the stress change on the surface of the copper wire and the temperature rise during the drawing process, the surface of the wire core after drawing is easily oxidized, and the surface turns red and black. The existing solution is to coat the surface of the copper wire with an antioxidant during the copper rod drawing process, but after drawing, the antioxidant almost all falls off, resulting in no subsequent antioxidant effect. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a device for coating the surface of the core of a cable copper wire with an antioxidant after wire drawing. After the copper rod is drawn, an antioxidant coating device is added to the core surface, and annealing treatment is performed after the antioxidant is coated.

[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 It is a structural schematic diagram of the roller of the utility model. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, a device for coating the core surface of a cable copper wire with an antioxidant after drawing comprises an infiltration tank 1, in which an infiltration liquid is arranged, and an antioxidant is added to the infiltration liquid; the drawn copper wire passes through an inlet roller 2, an infiltration roller 3 and an outlet roller 4 in sequence, and the infiltration roller 3 is located below the liquid level of the infiltration liquid.

[0015] Preferably, two wetting rollers 3 are provided, and a wire outlet roller 4 is arranged above the rear wetting roller 3. The wire outlet roller 4 is arranged above the wetting roller 3, so that the copper wire after wetting moves vertically upward, and the excess wetting liquid attached to the surface of the copper wire will flow down under the action of gravity and fall back into the wetting tank 1.

[0016] Preferably, a drying tunnel 5 is provided between the rear impregnation roller 3 and the outlet roller 4. The drying tunnel 5 accelerates the drying of the impregnation liquid and preheats it for the subsequent annealing operation.

[0017] Preferably, the drying tunnel 5 is an electrically heated drying tunnel.

[0018] Preferably, a liquid inlet pipe 6 is provided at the bottom of the infiltration tank 1 and an overflow pipe 7 is provided at the top to keep the liquid level in the infiltration tank stable.

[0019] Preferably, Figure 2 As shown, the roller is a dumbbell-shaped structure with thick ends and thin middle, which is convenient for limiting the position of the copper wire.

[0020] When in use, the copper wire comes out of the wire drawing machine and enters the impregnation tank 1 to be coated with the anti-oxidation impregnation liquid. After the impregnation is completed, the copper wire moves vertically upward and leaves the impregnation liquid. During the continuous rising process, the excess impregnation liquid slides off the surface of the copper wire and enters the drying tunnel 5 for drying and preheating.

[0021] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
