Improved ink jet mechanism

The invention provides an improved ink jet mechanism, and belongs to the technical field of printing machinery. The improved ink jet mechanism comprises a conveying channel, a working flat plate, at least one nozzle and an adjusting component, wherein the conveying channel is horizontally arranged and used for conveying a printing medium; the working flat plate is movably mounted above the conveying channel, and can be displaced in the vertical direction to be near or far from the conveying channel; the nozzle is detachably inserted on the working flat plate; an ink outlet for jetting ink to the printing medium is arranged on the lower end surface of the nozzle; the ink jet direction of the ink outlet is perpendicular to the conveying direction of the conveying channel; the adjusting component is arranged on the working flat plate, and is corresponding to the nozzle one to one; the adjusting component is used for adjusting the position of the lower end surface of the corresponding nozzle to finally enable the lower end surface of the nozzle to be parallel to the conveying channel; and a vertical distance from the lower end surface of the nozzle to the printing medium at the right lower side is a preset distance. The improved ink jet mechanism has the advantages of convenience for adjustment and ideal ink jet effect.
