PURPOSE: A nozzle block assembly with the capabilities for assembly and the accuracy for printing for an inkjet marking device is provided to mechanically control the ink pressure by including a pressure regulating member inside the nozzle block. CONSTITUTION: A nozzle block assembly comprising of an inkjet marking device comprises a head base plate(110), a nozzle block(120), a nozzle plate(130), and a pressure regulating member(140). The head base plate is joined at the marking on the basic body. The nozzle block comprises an ink flowing chamber, an ink supply pipe, and an ink collecting pipe. The nozzle plate is joined at on one side of the nozzle block and comprises a nozzle hole. The pressure regulating member is arranged perpendicularly to the nozzle hole and the ink collecting pipe, thereby regulating the pressure of the ink by generating resistance to the movement of the ink in the inside of the ink flowing chamber.
