Description

Hot tinning machine

Technical Field

The invention belongs to the technical field of tinning machines, and particularly relates to a hot tinning machine.

Background

Tinned copper wire is copper wire with a thin layer of metallic tin plated on the surface of the copper wire. The tinned copper wire is soft in material and good in conductivity, and compared with a bare copper wire, the tinned copper wire is higher in corrosion resistance and oxidation resistance, and the service life of a weak current cable can be greatly prolonged.

The tinning of copper wire is mainly to prevent copper from being oxidized to form a film, verdigris, by exposure to air, which is very poor in electrical conductivity and increases resistance. The tinned copper wire can prevent oxidation-reduction reaction and generation of verdigris; heat dissipation can be increased; the conductivity can be improved, and the performance of the lead can be improved; in addition, tinning of the copper wire can prevent the insulating rubber from being sticky, the wire core from blackening and becoming brittle and improve the weldability of the wire core. The tinned copper wire is mainly used as a conductive wire core of rubber-insulated mining cables, flexible wires, flexible cables, marine cables and the like, and is used as an outer shielding braided layer and an electric brush wire of the cable.

In the process of carrying out zinc tin plating on the surface of a copper wire by using the conventional copper wire tinning machine, the copper wire is opened due to uneven pulling force, and tin liquor on the surface of the copper wire is not effectively dried in time after the copper wire is tinned, so that the tin liquor on the surface of the copper wire falls off when the copper wire is rolled, and the surface of the copper wire cannot be completely covered by the tin liquor; and the content of elemental copper in the tin liquid tank is gradually increased, so that the tin plating effect of the tin liquid is poor, and meanwhile, the phenomenon of tin liquid precipitation cannot be timely solved.
