The present invention discloses a wet lead wire preparing and drying integrated machine and a wet lead wire preparing and drying integrated method, the wet lead wire preparing and drying integrated machine is mainly composed of a lead wire paper tray (1), a quantitative dosing device (2), a drying device (3), a rack (4) and a lead wire twisting and collecting device (5); firstly, the lead wire paper tray (1) is put on the rack, lead wire paper artificially passes through a dosing site of the quantitative dosing device (2), passes through the drying device (3), and then enters into the lead wire twisting and collecting device (5) for well fixing; secondly, an artificially mixed wet chemical agent is added into a chemical agent hopper of the quantitative dosing device (2); then the drying device (3) works, and when the temperature reaches the set temperature, the lead wire twisting and collecting device (5) is started automatically for lead wire preparing production. The wet lead wire preparing and drying integrated machine is applicable to the production of lead wire preparing production in fireworks industry, lead wires are directly dried on line, and directly coiled and packed into a finished product for storage without backwinding, sun-drying, and re-backwinding, and the production process is no longer limited by environmental conditions.
