Abstract

PURPOSE:To manufacture a jetting head at low cost by forming an ink reservoir in an upper and a lower plates constituting a jetting head section through draw forming. CONSTITUTION:An ink reservoir is formed in an upper plate 4 through draw forming. Moreover, an ink reservoir is formed similarly in a lower plate 6. A nozzle plate 5 is held between the upper and lower plates 4,6, to which is added pressure from both sides, A piezoelectric element 12 is bonded to the front surface of each of ;the upper and lower plates 4,6. The nozzle plate 5 is half-eched on both surfaces thereof to form the flowing pattern of the ink. Ink A and B enter through ink holes 9 formed in the plates 4,6 after thermal press, respectively. Since the interior rapping process of the nozzle plate 5 can be omitted, the manufacturing time can be shortened.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ejection head in an inkjet printer.

In the ejection head of a conventional inkjet printer, as shown in FIG. 4, an ink retaining ink route is formed by heat-pressing a nozzle plate 2 forming the ejection head with an upper plate 1 and a lower plate 3 from both sides. There is.

The piezo 12 bonded to both sides of the upper plate 1 and the lower plate 3 vibrates due to the current from the current source, and the piezo 12 vibrates through the upper plate 1 and the lower plate 3 to the nozzle plate 2.
The ink route is vibrated, and ink is ejected from the nozzle hole formed at the tip of the nozzle plate 2.

In this case, the ink retainers on the nozzle plate pass through the ink routes on both sides, so one nozzle plate can only hold one type of ink. Because of the subsequent thermo-pressure welding process, we have no choice but to rely on wire cut machining or electrical discharge machining to avoid burrs and sag during machining.

Referring to FIG. 1, in one embodiment of the present invention, an ink stopper is formed on the top plate 4 by drawing. The same applies to the lower plate 6. The nozzle plate 5 is sandwiched between the upper plate 4 and the lower plate 6 and pressed from both sides, and the piezo 12 is bonded to the front surfaces of the upper plate 4 and the lower plate 6. The nozzle plate 5 is half-etched on both sides to form an ink flow pattern.

Next, FIG. 3 shows a cross-sectional view of the plates 4, 5.6 after thermo-pressure welding, and shows that ink AIO and ink Bll are respectively inflowed from the ink inflow holes 9 provided in the plates 4.6. It shows. Furthermore, since the internal punching process of the nozzle plate 5 is eliminated, the processing time for the nozzle plate 5 is shortened, and the cost of the ejection head is reduced.
