Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to drying equipment for copper wire tinning production. Background Art

[0002] Tinning of copper wire can prevent the insulating rubber from becoming sticky, the wire core from becoming black and brittle, and improve its solderability. Tinned copper wire is mainly used in rubber-insulated mining cables, soft wires, soft cables and marine cables as conductive cores, as well as used as the outer shielding braid and brush wire of the cable.

[0003] However, the metallic tin liquid attached to the copper wire is difficult to solidify in time. Under the current conditions, it can only be transported over long distances to wait for the natural condensation of the metallic tin liquid. However, this natural air-drying method is not only inefficient, but also very easy to cause the metallic tin liquid to fall off due to the shaking of the copper wire during the transmission process, which not only easily causes pollution and waste of the metallic tin liquid, but also seriously affects the processing quality of the copper wire tin plating, which is not conducive to the subsequent processing and use of the copper wire.

A telescopic rod 9 movably pulled by the automatic telescope 7 is slidably sleeved in the guiding long groove 8, and a limiting clamping guard plate 10 for clamping the copper wire is integrally connected to the telescopic rod 9. It should be noted that the two The center lines of the limit clamp guards 10 are symmetrically arranged, and the two automatic retractors 7 are symmetrically arranged. Under the driving action of the automatic retractor 7, the two limit clamp guards 10 clamp and fix the two ends of the copper wire. An extension bracket 11 is fixedly installed on the upper end of the chassis 1, and a drive motor 12 is fixedly installed on the extension bracket 11. The output end of the drive motor 12 is key-connected with a drive gear 13 meshing with one of the driven gears 6. The driven gear 6 can be rotated by the drive gear 13, thereby driving the copper wire to rotate, which is convenient for the high-temperature hot air to dynamically heat the copper wire.

[0025] The heater 15 is connected to the lower port of the heat exhaust pipe 16, and the copper wire is located above the upper port of the heat exhaust pipe 16. The high-temperature hot air transported upward dynamically heats the rotating copper wire.

[0026] It should be noted that the specific models and specifications of the drive motor 12 and the heater 15 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.
