Liquid-flow hank dyeing machine

A liquid-flow hank dyeing machine includes an upright tank, at least a pair of hank hanging rods, a nozzle mechanism, a dye storage space, and a pump. The hank hanging rods are disposed in the upright tank for allowing at least one hank hung thereon. At least one of the hank hanging rods is a hollow pipe. The hollow pipe has a pipe wall. The pipe wall defines a flow channel. The pipe wall has at least one flow-directing hole. The flow-directing hole fluidly communicates with the flow channel through the pipe wall. The nozzle mechanism is disposed in the upright tank and above the hank hanging rods. The dye storage space is disposed in the upright tank and below the hank hanging rods. The pump fluidly communicates with the dye storage space, the flow channel, and the nozzle mechanism for pumping a part of dye from the dye storage space to the nozzle mechanism and pumping another part of the dye from the dye storage space to the flow channel.
