Problems solved by technology

[0004] At present, most of the large-character nozzles of non-contact inkjet printers have complex structures and high failure rates. The ink pressure is not high, the ink is easy to leak, and the ink pipeline and wire are exposed, which is not convenient for packaging and transportation. Once the ink tube is accidentally broken during work, it is easy to cause personal and equipment safety accidents

Abstract

The invention discloses a jetting head for a non-contact type large-character ink-jet printer. The jetting head for the non-contact type large-character ink-jet printer comprises an installation base, a jetting cavity, a jetting nozzle board, a static core module, a valve pipe module, a movable core assembly, a driving coil and a jetting head cable. The jetting nozzle board is sealed on the jetting cavity. A row of jetting holes are formed in the jetting nozzle board. The jetting cavity is connected with a jetting head ink supply pipe and a backflow pipe. The valve pipe module is fixed to the installation base. The static core module is connected with the installation base through the valve pipe module. Electromagnetic valves, independently controlling the jetting holes in the jetting nozzle board to jet ink, of ink droplets are formed by the static core module, the valve pipe module, the movable core assembly and the driving coil together, wherein the number of the electromagnetic valves is identical to that of the jetting holes in the jetting nozzle board. The jetting head for the non-contact type large-character ink-jet printer has the advantages of being simple in structure, high in interchangeability, convenient to repair, low in cost, good in performance, convenient to use, practical and safe.

Description

[0001] technical field [0002] The invention relates to the technical field of inkjet printers, in particular to a technology for a spray head of a non-contact large-character inkjet printer. [0003] Background technique [0004] At present, most of the large-character nozzles of non-contact inkjet printers have complex structures and high failure rates. The ink pressure is not high, the ink is easy to leak, and the ink pipes and wires are exposed, which is not convenient for packaging and transportation. Once the ink pipe is accidentally broken during work, it is easy to cause personal and equipment safety accidents. [0005] Contents of the invention [0006] In order to overcome the defects of the prior art, the object of the present invention is to provide a simple structure, high interchangeability, convenient maintenance, low cost, good performance, convenient and practical, and a safe spray head for non-contact large-character inkjet printers . [0007] Techni...
