[0035] In this embodiment, the image detector 6 can be an industrial camera, such as a CCD linear array camera, etc., which includes an O-shaped light source for illumination. During operation, the image detector 6 acquires the fabric surface image in real time online and transmits the acquired fabric surface image to the controller in real time. The controller receives the image data of the fabric surface provided by the image detector 6 in real time, and drives the printing nozzle 3 to move up or down through the vertical driving component 5, thereby aligning the printing nozzle 3. Then, the controller controls the horizontal driving component 4 to drive the printing nozzle 3 to move left and right for printing on the fabric, which can more accurately align the printing nozzle 3 to meet more printing requirements and improve the practicality of the device.

[0036] Please refer to Figure 2 , in this embodiment, the horizontal driving component 4 includes a driving motor 41, a transmission lead screw 42, a transmission nut 43, and two linear guide blocks 44. Among them, the driving motor 41 is arranged on the U-shaped frame 2, the driving motor 41 is electrically connected to the controller, the transmission lead screw 42 is arranged between the two legs of the U-shaped frame 2, the driving motor 41 drives the transmission lead screw 42 to rotate, the transmission nut 43 is threadedly connected to the transmission lead screw 42, the two linear guide blocks 44 are symmetrically arranged on the side of the transmission nut 43, and one end of the linear guide block 44 away from the transmission nut 43 is slidably connected to the guide groove 21 on the inner side wall of the U-shaped frame 2, and the setting direction of the guide groove 21 is along the length direction of the top plate of the U-shaped frame 2.

[0037] During specific operation, the controller controls the driving motor 41 to start, the driving motor 41 drives the transmission lead screw 42 to rotate. Due to the action of the transmission nut 43 and the linear guide block 4, the transmission nut 43 moves back and forth left and right under the U-shaped frame 2, thereby driving the printing nozzle 3 to move left and right for printing on the fabric.
