[0046] The working principle of the embodiment is as follows: the infrared sensor on the temporary storage rack 32 monitors the number of yarn packages to be dyed in real time, ensuring sufficient supply; the loading mechanical arm 31 identifies the position and size of the package on the temporary storage rack through a high-definition industrial camera, and the end pneumatic gripper (with a silicone pad wrapped on the inside) accurately grabs the package to avoid yarn damage or package deformation during the grabbing process; when installing the yarn package, the first cylinder 46 pushes the connecting block 45 and the fixed shell 43 to move to the rear side of the dyeing chamber 2, so that the rear fixed main shaft 42 extends to the outside of the dyeing chamber 2, and waits for loading; the loading mechanical arm 31 puts the grabbed package on the yarn package fixing assembly 48 of the rear fixed main shaft 42, and the electric four-jaw chuck 481 adjusts the extension length of the telescopic block 482 according to the inner diameter of the package, so that the butyronitrile rubber protrusion 485 on the outside of the fixed plate 484 is attached to the inner wall of the package, and the package is stably fixed by friction; after fixing, the second cylinder 49 is retracted, so that the package returns to the dyeing position between the two groups of communication arc-shaped blocks 52 in the dyeing chamber 2; during the dyeing process, the drive box 41 and the fixed main shaft 42 rotate slowly, so that the package rotates synchronously, and the radial and axial airflow of the multi-directional airflow dyeing liquid circulating mechanism 5 is used to ensure that the yarn is evenly contacted with the dyeing liquid; after dyeing, the drive motor 44 drives the drive box 41 and the fixed main shaft 42 to rotate 180°, so that the dyed package is exchanged with the fixed main shaft 42 position of the uninstalled package; at this time, the first cylinder 46 is retracted, so that the fixed main shaft 42 with the dyed package moves to the front end of the dyeing chamber 2, the yarn package fixing assembly 48 is released, the second cylinder 49 pushes the corresponding push end cover 47, and the package is pushed from the fixed main shaft 42 to the unloading conveyor belt 33, and the conveyor belt transports the package to the drying pretreatment module 34 for preliminary drying, and the whole process is completed, and the fixed main shaft 42 of the uninstalled package repeats the above steps for yarn package installation and dyeing operation.
