However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] The effect achieved by the entire embodiment 1 is that the nozzle of the coating machine placed on the placement plate 11 is moved into one of the cleaning tanks 3 by the provided lifting mechanism 8, and the ultrasonic generator 4 is used to generate ultrasonic waves by high-frequency vibration. The ultrasonic radiation generates a large number of bubbles in the cleaning liquid, and the air pressure shock wave generated when the bubbles burst destroys the adsorption of dust and stains on the coating machine nozzle, so that the dust and stains are separated from the coating machine nozzle. Subsequently, the nozzle of the coating machine placed on the placement plate 11 is moved upward and leaves one of the cleaning tanks 3 by the provided lifting mechanism 8, and then the first A driving motor 12 is used, so that the first driving motor 12 drives the rotating wheel 13 to rotate, and the rotating wheel 13 drives the belt 14 to move, thereby driving the screw 6 to rotate. Since the fixed frame 5 limits the movable seat 7, the screw 6 drives the movable seat 7 to move, and the movable seat 7 drives the lifting mechanism 8 to move, thereby driving the coating machine nozzle placed on the placement plate 11 to move. After the coating machine nozzle moves to the top of another cleaning tank 3, the first driving motor 12 is turned off, and then the operation is repeated, so as to facilitate the secondary cleaning of the coating machine nozzle placed on the placement plate 11, improve the cleaning effect, and clean comprehensively.

[0024] Example 2: Figure 1 - Figure 4 As shown, the lifting mechanism 8 includes a fixed shell 801, which is fixedly connected to the top of the movable seat 7, and a pressure cylinder 802 is installed on the inner top of the fixed shell 801. The output end of the pressure cylinder 802 is fixedly connected to a hydraulic rod 803, and a limiting groove 804 is provided on one side of the fixed shell 801. The bottom end of the hydraulic rod 803 is fixedly connected to a support plate 805, and the support plate 805 movably passes through the limiting groove 804.

An electric heating tube 902 is provided in the drying shell 901, and a protective net 903 is bolted to the top of the drying shell 901. The inner side of the drying shell 901 is fixedly connected to a mounting frame 904, and a second drive motor 905 is fixedly installed on the inner surface of the mounting frame 904. The output end of the second drive motor 905 is provided with a fan blade 906. One side of the cleaning pool 2 is fixedly connected to a drain pipe 15, and a control valve 16 is provided on the drain pipe 15.

[0025] The effect achieved by the entire embodiment 2 is that, by providing a lifting mechanism 8, the pressure cylinder 802 is started, so that the pressure cylinder 802 drives the hydraulic rod 803 to move downward, the hydraulic rod 803 drives the support plate 805 to move downward, the support plate 805 drives the connecting rod 10 to move downward, and the limiting groove 804 limits the support plate 805, thereby improving the stability of the support plate 805 during the movement, thereby driving the coating machine nozzle placed on the placement plate 11 to move downward and enter the cleaning tank 3, so as to facilitate the cleaning operation thereof, and then by providing a drying mechanism 9, the electric heating tube 902 is energized to generate heat, heating the air near the electric heating tube 902, and at the same time starting the second driving motor 905, so as to drive the fan blade 906 to rotate, and use the hot air to facilitate the drying of the coating machine nozzle, and then by opening the control valve 16, the cleaning liquid in the cleaning tank 3 is discharged through the drain pipe 15.

[0026] Working principle: When in use, by starting the pressure cylinder 802, the pressure cylinder 802 drives the hydraulic rod 803 to move downward, the hydraulic rod 803 drives the support plate 805 to move downward, and the support plate 805 drives the connecting rod 10 to move downward, thereby driving the coating machine nozzle placed on the placement plate 11 to move downward and enter one of the cleaning tanks 3, and then the ultrasonic generator 4 is used to vibrate at high frequency to generate ultrasonic waves, and the ultrasonic radiation generates a large number of bubbles in the cleaning liquid, and the air pressure shock wave generated when the bubbles burst is used to destroy the adsorption of dust and stains on the coating machine nozzle, so that the dust and stains are separated from the coating machine nozzle, and then the pressure cylinder 802 is started to shrink, so that the coating machine nozzle placed on the placement plate 11 moves upward and leaves one of the cleaning tanks 3, and then the first drive motor 12 is started so that the first drive motor 12 The rotating wheel 13 is driven to rotate, and the rotating wheel 13 drives the belt 14 to move, thereby driving the screw 6 to rotate. Since the fixed frame 5 limits the movable seat 7, the screw 6 drives the movable seat 7 to move to the right, and the movable seat 7 drives the lifting mechanism 8 to move to the right, thereby driving the coating machine nozzle placed on the placement plate 11 to move to the right, so that the coating machine nozzle moves to the top of another cleaning tank 3 and then turns off the first drive motor 12, and then repeats the operation to perform a second cleaning of the coating machine nozzle, thereby improving the cleaning effect. After cleaning, the coating machine nozzle placed on the placement plate 11 is located directly above the cleaning tank 2, and finally the electric heating tube 902 is energized to generate heat to heat the air near the electric heating tube 902, and at the same time, the second drive motor 905 is started to drive the fan blade 906 to rotate, and the coating machine nozzle can be dried by hot air.
