[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: Hard anodizing coloring bath for aluminum alloy surface, please refer to [link / reference]. Figures 1-6 The system includes a coloring pool body 1, a water outlet pipe 2, a valve 3, a connecting rod 4, a rodless cylinder 5, a slider 6, and a feeding structure. The water outlet pipe 2 is connected to the right side of the coloring pool body 1, and a valve 3 is installed on the water outlet pipe 2. A connecting rod 4 is connected to the right side of the valve 3. Two rodless cylinders 5 are installed at the rear of the coloring pool body 1, and sliders 6 are installed on the rodless cylinders 5. The two sliders 6 share a feeding structure for placing workpieces. The feeding structure includes a placement frame 7, screws 8, and a rotating plate 9. The placement frame 7 is detachably mounted on the upper part of the two sliders 6, and two screws 8 are screwed onto the upper part of the placement frame 7, which are threaded to the sliders 6. A rotating plate 9 is rotatably mounted on the front side of the placement frame 7. A support frame 10 is fixedly connected to the rear of the coloring pool body 1, and a fan 11 is installed on the top of the support frame 10. A connecting pipe 12 is connected to the rear of the fan 11. A filter frame 13 is placed on the side, and an isolation plate 14 is placed on top of the filter frame 13. One end of the connecting pipe 12 is connected to the isolation plate 14. Both rotating shafts of the rotating plate 9 are equipped with damping rings 18. The damping rings 18 are used to increase the rotation resistance and prevent the rotating plate 9 from rotating accidentally. Two protective shells 19 are fixedly connected to the upper rear side of the coloring pool body 1. The rodless cylinder 5 is located inside the protective shell 19. The protective shell 19 plays a role in protection and heat insulation, preventing the external environment from interfering with the rodless cylinder 5. An isolation net 20 is set on the side of the fan 11 near the coloring pool body 1. The isolation net 20 is used to prevent foreign objects from entering the fan 11 and ensure the normal operation of the fan 11. An anti-slip sleeve 21 is fitted on the connecting rod 4 to facilitate the operator's grip and rotation of the valve 3. A handle 22 is fixedly connected to the top of the isolation plate 14. The handle 22 is used to increase the point of force and facilitate the removal of the isolation plate 14.

[0025] When surface treatment of a workpiece is required, firstly, an appropriate amount of electrolyte is injected into the coloring tank body 1, and the temperature is adjusted to the required process temperature using the temperature control system. Next, the rodless cylinder 5 is activated, driving the slider 6 upwards, which in turn lifts the placement rack 7. The rotating plate 9 is then rotated to open the placement rack 7, allowing the workpiece to be treated to be placed on it. Then, the rodless cylinder 5 again drives the slider 6 downwards, moving the placement rack 7 downwards, ensuring the workpiece is completely immersed in the electrolyte. The controller on the front of the coloring tank body 1 controls factors such as voltage, time, and temperature, allowing the workpiece surface to absorb dye and form various colors. During the coloring process, the fan can be activated. Fan 11 accelerates air circulation, drawing harmful gases generated during coloring into connecting pipe 12. These gases then enter filter frame 13 for purification, preventing them from escaping into the air and causing pollution or harming the health of operators. After coloring is complete, drive slider 6 to move upward, raising the placement rack 7. Rotate rotating plate 9 in the opposite direction to open placement rack 7, allowing the colored workpiece to be removed for subsequent cleaning or drying. When placement rack 7 needs to be replaced, loosen screw 8 to release the restriction on the old placement rack 7, remove it from slider 6, replace it with a new placement rack 7, and tighten screw 8 to ensure a secure fixation.

[0026] Example 2: Based on Example 1, please refer to... Figure 6 Two fixing plates 15 are fixedly connected to the lower left side of the coloring tank body 1. A motor 16 is installed on the fixing plate 15. Two stirring rods 17 are rotatably arranged inside the coloring tank body 1. The output shaft of the motor 16 is connected to the stirring rods 17 through a coupling.

[0027] During the coloring process, motor 16 can be started. The output shaft of motor 16 rotates and drives the stirring rod 17 to rotate, stirring the electrolyte in the coloring tank, making the dye distribution more uniform, thereby improving the consistency and efficiency of coloring.
