미설명부호는 노즐블록 상판(2a), 볼트체결공(6), PCB 기판(7), 마감재(12), 조절홈(15)이다.Reference numerals are nozzle block top plate 2a, bolt fastening hole 6, PCB substrate 7, finish 12, adjusting groove 15.

여기서 노즐블록 상판(2a)은 분리되어 있는 것처럼 도시되어 있으나, 실제로는 노즐블록(2)과 일체로 형성되어 있다.Here, the nozzle block top plate 2a is shown as being separated, but is actually formed integrally with the nozzle block 2.

상기 노즐플레이트(1)에 형성된 잉크분사홀(5)은 도 2에 도시된 것과 같이 지그재그 형태로 구성하여 잉크분사홀(5) 사이의 간격을 줄일 수 있는 것이 바람직한데, 이는 잉크분사홀(5)의 간격이 좁을수록 작은 문자 인쇄가 가능하고 고품질의 인쇄가 가능하다.The ink injection hole 5 formed in the nozzle plate 1 may be configured in a zigzag form as shown in FIG. 2 to reduce the distance between the ink injection holes 5, which is an ink injection hole 5. The narrower the interval, the smaller the character print and the higher quality print.

상기 플런저(10)의 일단에는 잉크분사홀(5)을 용이하게 막기 위해 마감재(12)를 부착하는 것이 바람직한데, 상기 마감재(12)는 합성고무재와 같은 합성수지재가 적합하며 유성잉크에 반응하지 않는 소재가 더욱 바람직하다.One end of the plunger 10 is preferably attached to the finishing material 12 to easily block the ink injection hole (5), the finishing material 12 is a synthetic resin material, such as a synthetic rubber material is suitable and does not react to oil-based ink Material is more preferred.

상기 파이프(11)는 도시된 바와 같이 원통형으로 형성하고, 상기 파이프(11)의 일단에는 나사산이 형성된 체결부재(14)가 형성되어 상기 체결부재(14)로서 노즐블록(2)에 결합할 수 있으며, 이와는 별도로 상기 파이프(11)의 일부 외주면에 나사산을 형성하여 상기 체결부재(14)와 파이프(11)를 일체로 형성할 수도 있다.The pipe 11 is formed in a cylindrical shape as shown, and one end of the pipe 11 is formed with a threaded fastening member 14 can be coupled to the nozzle block 2 as the fastening member 14. In addition, the fastening member 14 and the pipe 11 may be integrally formed by forming a screw thread on a part of the outer circumferential surface of the pipe 11.

상기 노즐블록(2)은 노즐플레이트(1)와 밀착 결합되어 있으며 내부에 잉크가 충진된다. 이때 노즐블록(2)과 노즐플레이트(1) 사이에는 패킹부재(도시하지 않음)를 형성할 수 있다.The nozzle block 2 is tightly coupled to the nozzle plate 1 and filled with ink therein. In this case, a packing member (not shown) may be formed between the nozzle block 2 and the nozzle plate 1.

상기 노즐블록(2)의 일측에는 하나 이상의 잉크공급관(3)을 형성하고, 상기 잉크공급관(3)으로 잉크가 공급된다. 상기 잉크공급관(3)으로 공급된 잉크는 노즐블록(2) 내에 충진되어 있게 되는데, 노즐블록(2) 내의 잉크는 잉크공급부로부터 압력을 받아 노즐플레이트(1)의 잉크분사홀(5)이 개방되면 밖으로 분출된다.At least one ink supply pipe 3 is formed at one side of the nozzle block 2, and ink is supplied to the ink supply pipe 3. The ink supplied to the ink supply pipe 3 is filled in the nozzle block 2, and the ink in the nozzle block 2 is pressurized by the ink supply part to open the ink injection hole 5 of the nozzle plate 1. When it bursts out.

도 4는 본 발명의 사용상태예시도로서, 노즐블록(2)에 파이프(11)가 나사 결합되어 있으며, 상기 파이프(11)를 따라 플런저(10)가 왕복운동을 한다. 상기 코일(4)에 전류를 흘려주게 되면 플런저(10)가 파이프(11) 속으로 들어가게 되고, 노즐플레이트(1)에 형성된 잉크분사홀(5)이 개방되게 된다.4 is a view illustrating the use state of the present invention, in which a pipe 11 is screwed to the nozzle block 2, and the plunger 10 reciprocates along the pipe 11. When the current flows through the coil 4, the plunger 10 enters the pipe 11, and the ink injection hole 5 formed in the nozzle plate 1 is opened.

상기한 잉크분사홀(5)이 개방됨과 동시에 잉크가 밖으로 분사되고, 이후 코일(4)에 흐르는 전류를 차단하게 되면 압축스프링(13)에 의해 플런저(10)가 원위치되어 잉크분사홀(5)을 닫게 된다.When the ink injection hole 5 is opened and ink is ejected at the same time, when the current flowing through the coil 4 is cut off, the plunger 10 is returned to the ink injection hole 5 by the compression spring 13. Will be closed.

상술한 분사동작을 반복하면서 인쇄가 진행된다.Printing proceeds while repeating the above-described injection operation.

상기 파이프(11)의 일단에는 조절홈(15)을 형성하여, 드라이브 등의 공구로 파이프(11)를 회전시켜 상기 파이프(11)와 노즐블록(2)의 결합량을 조절할 수 있다. 즉, 파이프(11)가 노즐블록(2) 내로 들어갈수록 잉크분사홀(5)을 개방해주는 시간이 짧아져 잉크분사량이 적어지게 되고, 반대로 파이프(11)가 노즐블록(2) 밖으로 나올수록 잉크분사홀(5)을 개방해주는 시간이 길어지게 되어 잉크분사량이 많아지게 된다.One end of the pipe 11 may be formed with an adjusting groove 15 to adjust the coupling amount of the pipe 11 and the nozzle block 2 by rotating the pipe 11 with a tool such as a drive. That is, as the pipe 11 enters the nozzle block 2, the time for opening the ink injection hole 5 is shortened, so that the amount of ink injection decreases. On the contrary, as the pipe 11 comes out of the nozzle block 2, the ink As the time for opening the injection hole 5 becomes long, the ink injection amount increases.

상기 노즐블록(2)에 결합된 파이프(11)의 결합량 조절과는 별개로, 코일(4)에 흐르는 전류의 시간과 세기를 조절해줌으로써 잉크분사량을 조절할 수도 있다. 즉, 오랜 시간 동안 코일(4)에 전류를 흘려주게 되면 플런저(10)가 오랜 시간 동안 파이프(11) 내로 들어가게 되어 잉크분사홀(5)의 개방시간이 길어지고, 반대로 짧은 시간 동안 코일(4)에 전류를 흘려주게 되면 잉크분사홀(5)의 개방시간이 짧아지게 되어 잉크분사량이 적어지게 된다.Apart from adjusting the coupling amount of the pipe 11 coupled to the nozzle block 2, the ink injection amount may be adjusted by adjusting the time and intensity of the current flowing through the coil 4. That is, when the current is supplied to the coil 4 for a long time, the plunger 10 enters the pipe 11 for a long time, and the opening time of the ink injection hole 5 becomes long, and conversely, the coil 4 for a short time. When the current is flowed through), the opening time of the ink injection hole 5 is shortened, so that the ink injection amount is reduced.

상술한 바와 같이, 본 발명은 노즐플레이트에 형성된 잉크분사홀을 병렬로 구성하고, 상기 잉크분사홀을 개폐시켜주는 플런저 역시 병렬로 형성하여, 잉크젯프린터 헤드의 크기를 작게 구성할 수 있을 뿐만 아니라 보다 작은 활자의 인쇄가 가능하고 인쇄품질을 높일 수 있는 잉크젯프린터 헤드를 제공한다.As described above, in the present invention, the ink jetting holes formed in the nozzle plate are configured in parallel, and the plungers for opening and closing the ink jetting holes are also formed in parallel, so that the size of the inkjet printer head can be made smaller. It provides inkjet printer head that can print small print and improve print quality.
