when the spray coating device is used, the adjusting motor is started firstly, the adjusting motor drives the screw rod to rotate, the screw rod drives the threaded sleeve to move and adjust, and the threaded sleeve drives the spray coating plate to move and adjust, so that the spray coating range is adjusted and controlled;
s2, when the spraying plate moves outwards, the spraying plate drives the linkage toothed plate to move, the linkage toothed plate drives the gear to rotate, the gear drives the driven toothed plate to move inwards, the driven toothed plate drives the expansion plate to expand inwards, the problem that an opening below a spraying range is enlarged after the spraying plate moves is compensated, and the stability of negative pressure suction is maintained;
s3, after the spraying range is adjusted according to the use requirement of the equipment, the adjusting motor is closed, the spraying assembly is started to carry out spraying treatment, and in the spraying process, the negative pressure fan unit and the combustion chamber are started;
s4, negative pressure suction is carried out on VOC gas in the spraying range through the reflux cavity and the negative pressure pipe by the negative pressure fan unit, and the gas after the negative pressure suction is transmitted to the inside of the combustion box for full combustion treatment.
