The frame 1 is a slide rail bridge structure, and the moving component and the inkjet identification component are integrated and installed on the slide rail crossbeam of the frame 1, so that the integrated standby position of the inkjet identification component can be adjusted.

[0043] Furthermore, the moving component includes: an X-axis linear module 4 and a Z-axis linear module 5; wherein, the Z-axis linear module 5 is arranged on one side of the frame end, and the X-axis linear module 4 is arranged on one side of the Z-axis linear module 5; the X-axis linear module 4 is used to realize driving the inkjet marking component to move forward and backward along the X-axis; the Z-axis linear module 5 is used to realize driving the inkjet marking component to move up and down along the Z-axis.

The encoder 7 is installed on the end of the transmission shaft of the original conveying and lifting roller 12, and is used to detect the real-time conveying speed of the steel pipe 11, and transmit it to the control cabinet 9 of the inkjet device, so that the inkjet terminal 2 automatically matches the speed of inkjet according to the conveying speed, ensuring that the sprayed identification code is not deformed.

[0047] Furthermore, the sensor 8, the air knife 6, the spray terminal 2 and the UV curing lamp 3 are arranged in sequence against the running direction of the steel pipe 11, forming an efficient and orderly working system, ensuring the smooth progress of the entire coding operation.

The modularly designed inkjet device supports a variety of fonts, can print numbers, characters, icons, and can also print QR codes, barcodes and other content. It supports variable data document printing and provides an interface to connect with the system to achieve traceability management of enterprise products.
