The utility model provides a novel independent air supply airflow dyeing machine, which comprises a main cylinder, an elevation roller, a fan, a nozzle assembly which is connected with the fan, and the like. The fan of the existing airflow dyeing machine is installed at one side of the main cylinder and is connected with a long roundabout air duct. The fan is arranged on the top of the main cylinder, an outlet of the fan is in butt joint with an airflow inlet of the nozzle assembly, and an outlet pipeline of the fan reaches the nozzle assembly in a shortest route. A clearance between an upper nozzle drum and a lower nozzle drum in the nozzle assembly forms a first nozzle port, a clearance between an intercepting ring and the tail part of the lower nozzle drum forms a second nozzle port, a U-shaped baffle plate is arranged between the tail part of the lower nozzle drum and the intercepting ring, so that the airflow is concentrated below the nozzle port to be injected. The utility model also provides a novel dye liquid spraying device and a plurality of spraying modes. Due to the adoption of the independent air supply airflow dyeing machine, the efficiency and the dyeing quality of the airflow dyeing machine are improved.
