[0017] By adopting the above technical scheme, the driving pump starts to drive the water in the water inlet pipe to flow into the dyeing machine body, and at the same time, the driving motor starts to drive the driving fan blades to move. The driving fan blades move to mix the dye liquid in the dyeing machine body and drive the dye liquid to flow, so that the dye liquid is discharged from the dyeing machine body from the water outlet pipe, thereby completing the driving work of moving the liquid in the water inlet pipe and the dyeing machine body.

[0018] Optionally, the water return mechanism includes:

The dye liquid is allowed to stand and stratify in the return water tank. Larger particles of impurities in the dye liquid are deposited at the bottom of the return water tank. The upper clear liquid is pumped into the first return water pipe by a pump. The first return water pipe pumps the dye liquid into the liquid separation tank.

[0046] 1. By opening the water inlet pipe, the cold water in the water inlet pipe enters the dyeing machine body under the action of the driving mechanism.
