The invention discloses a laser quick wire cutting machine, which comprises a foundation framework and a laser device, wherein a roller conveying device is arranged on the foundation framework and comprises two synchronous belts and a motor, the motor is used for driving the synchronous belts, the two synchronous belts are arranged on the foundation framework in parallel, a gap is formed between the two synchronous belts, the laser device comprises a laser head, the laser head vertically points the lower two synchronous belts, a dust collector is arranged at one side of the foundation framework, and an air suction opening of the dust collector is arranged between the two synchronous belts and is positioned just under the laser head. The laser quick wire cutting machine has the advantages that the remaining material on a roller is cut by the laser head at one time, the cut material is immediately sucked into a recovery bag by the dust collector, the pollution is avoided in the process, the required labor is saved, the recovery efficiency is greatly improved, and the running cost of enterprises is reduced.
