Background
Copper is widely used in the fields of electronic information, lubrication, catalysis, metallurgy, and the like because of its excellent properties and low price. However, copper is very easily oxidized in air, and the finer the particle size, the more severe the oxidation. Copper is oxidized by exposure to air to form a layer of copper, which is known as verdigris, whose poor conductivity increases resistance. In addition, the food-containing vessel may be harmful to human body after generating verdigris. In order to improve the oxidation resistance of copper, the surface of copper can be coated with inert metal. The inert metal layer is coated, so that the oxidation resistance of the copper can be remarkably improved, and the conductivity of the copper can be well maintained. Although tin is not an inert metal and is more reactive than copper, tin is stable in air at normal temperature, and a dense oxide film is generated on the surface of tin to prevent the tin from being oxidized continuously. Thus, tin plating the copper surface may improve the oxidation resistance of the copper to some extent. The tin-plated copper has good stability, conductivity, wear resistance, corrosion resistance and electromagnetic shielding property, and has good application prospect.
At present, the production process flow of the hot tinned copper wire comprises eight flows, namely paying off → annealing machine → acid cleaning → tinning furnace → cooling → traction → adding shaft guide oil (reducing tin ash) → winding and unwinding. In the prior art, the copper wire with a large diameter needs to be sprayed with pure water for cooling after being subjected to hot tinning, so that drying treatment is needed after cooling, otherwise, the copper wire can be oxidized, and the weldability quality of the tinned copper wire is influenced. The drying mode is often, through water-cooled tinned wire around on the reel, then take off, go to the stoving in the oven, because tinned wire can lean on each other after taking off together, moisture content is difficult to discharge when the stoving, is difficult for the stoving, if the time overlength, also easy oxidation, if add the temperature too high, melt the tin coating again easily.

The copper wire tinning dryer can quickly and effectively dry the moisture on the tinned copper wire cooled by cooling water. In addition, the two sets of driving units 601 drive the two wiping sponges 604 to tightly wipe the tinned copper wires 9 on the left side and the right side, so that the wiping sponges 604 can completely surround the tinned copper wires 9 to wipe in all directions, the effect of removing water drops and water drops is more ideal, the stress on the left side and the right side of the tinned copper wires 9 is mutually offset, and the problems of wire breakage and wheel dropping caused by the stress on one side are avoided; through the arrangement of the extrusion block 605 with the protrusions, the wiping sponge 604 can be extruded on the extrusion block 605 to effectively dewater when the driving unit 601 retracts, and the back of the extrusion block 605 can play a limiting role to prevent the connecting plate 602 from continuously advancing; through the setting of first collection funnel 606, be convenient for with the moisture of wiping off and wipe sponge 604 extrusion dehydration downdraft effectively collect and lead-in to the catch basin centralized processing. A cold air blowing unit 7 composed of the conical cylinder, the annular air pipe 701 and the air nozzle 702 is coaxially sleeved on the tinned copper wire 9 which is obliquely conveyed, and the sprayed low-temperature dry compressed air reversely blows water stains and water vapor off from the tinned copper wire 9; through the arrangement of the baffle 705 and the second collecting funnel 706, the baffle 705 blocks and leaves the moisture entrained in the wind, and the moisture collected and flowed down on the baffle 705 is guided to the water collecting tank through the second collecting funnel 706 for centralized treatment.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the scope of the present invention is defined by the claims.
