The invention provides a safety compound machine of sofa fabric. The safety compound machine of sofa fabric comprises a horizontal stand, a first unwinding mechanism and a reeling mechanism, wherein the first unwinding mechanism and the reeling mechanism are arranged at both sides of the horizontal stand. A roller coating box and a compound box are fixed on the horizontal stand, a second unwinding mechanism is arranged between the roller coating box and the compound box, the top of the inner side of the roller coating box is connected to multiple first drencher heads, the top of the inner side of the compound box is connected to multiple second drencher heads, a storage water tank is fixed to the upper end face of the outer side of the compound box, the outside of the storage water tank is connected to multiple flow pipes communicated to first drencher heads and second drencher heads respectively, smoke sensors are arranged both in the roller coating box and the compound box, regulating valves is connected to the flow pipes, and the smoke sensors and the controllers of the regulating valves are connected through electric signals. By the arrangement of the smoke sensor, a fire is found in time, and signals are sent to the regulating valves so as to spray water to wet the fabric and meanwhile to knock down the fire on the fabric; through a block component, the fired part is quickly disconnected so as to avoid fire spreading and meanwhile more intact fabrics can be stored.
