본 고안은 잉크제트 프린터의 난류차단장치에 관한 것으로 특히, 고속으로 회전하는 드럼 주위에 발생되는 유동난류에 의하여 잉크 노즐로부터 분사된 잉크입자의 이동경로가 휘어지는 현상을 배제하여 인자상태를 양호하게한 잉크제트 프린터의 난류차단장치에 관한 것이다.The present invention relates to a turbulence blocking device of an ink jet printer. In particular, the printing condition is improved by eliminating the warpage of the ink particles ejected from the ink nozzle by the flow turbulence generated around the drum rotating at a high speed. It relates to a turbulence blocking device of an ink jet printer.
일반적으로 사용되는 잉크제트 프린터에서는 고속회전하는 드럼의 주위를 따라 유동하는 기류(氣流)에 의해 잉크입자의 이동경로에 휨 현상이 발생되어 인자의 상태가 양호하지 못하게 되는 문제점이 있는바, 종래에는 이와같은 공기의 유동난류가 잉크입자에 미치는 영향을 제거하기 위한 수단이 구비되어 있지 않으므로 정교한 인자를 기할 수 없는 결함이 있었다.In general, an ink jet printer has a problem in that warpage occurs in a moving path of ink particles due to airflow flowing around a drum rotating at a high speed, and thus the printing condition is not good. Since there is no means for eliminating the influence of the flow turbulence of air on the ink particles, there is a defect that cannot be precisely factored.
본 고안은 이와같은 결함을 해소하기 위하여 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a defect, described in detail by the accompanying drawings as follows.
제1도에 도시한 바와같이, 잉크제트 헤드(1)에 부착된 압전소자(2)의 진동에 의해 잉크공급실(3)에서 노즐(4)을 통하여 분사된 잉크입자(5)가 대전전극(6)을 통해 대전되고 편향전극(7)에서 편향된 다음 미스트가이드(mist guide)(8)의 통과공 (8a)를 통과하여 드럼(9)에 부착된 인자용지에 정착되는 것에 있어서, 미스트가이드(8)의 후면에 요입부(10a)를 중간에 절곡형성한 난류방지구(10)의 일측확개부 (10b)를 고정하여 타측확개부(10c)의 단부가 드럼(9)과 일정간격 유지되게 하는 동시에, 난류방지구(10)에 형성된 요입부(10a)내측의 입자통과부(10d)가 미스트가이드(8)의 통과공(8a)과 동일직선상에 위치하게 한 것이다.As shown in FIG. 1, the ink particles 5 ejected through the nozzle 4 from the ink supply chamber 3 by the vibration of the piezoelectric element 2 attached to the ink jet head 1 are charged electrodes ( 6) is charged through the deflection electrode 7 and then passed through the through hole 8a of the mist guide 8 and settled on the printing paper attached to the drum 9; 8, the one side expansion portion (10b) of the turbulence prevention device 10 formed in the middle of the concave inlet portion (10a) is bent in the rear so that the end of the other expansion portion (10c) is maintained at a constant distance from the drum (9) At the same time, the particle passing portion 10d inside the concave inlet 10a formed in the turbulence preventing device 10 is positioned in the same line as the through hole 8a of the mist guide 8.
이와같이된 본 고안 난류차단장치는 인자시에 드럼(9)의 고속회전에 의하여 드럼(9)주위에 발생되는 유동난류가 제1도에 도시된 바와같이 난류방지구(10)에서 차단되어 잉크입자(5)의 이동경로에 영향을 끼치지 못하게 되므로 잉크입자가 미스트가이드(8)의 통과공(8a)과 난류방지구(10)의 통과부(10d)를 통해 직진하여 인자용지에 양호한 인자가 행하여진다.The turbulence blocking device of the present invention as described above has the flow turbulence generated around the drum 9 by the high-speed rotation of the drum 9 at the time of printing so as to be blocked by the turbulence preventing device 10 as shown in FIG. Since it does not affect the movement path of (5), the ink particles go straight through the through hole 8a of the mist guide 8 and the through part 10d of the turbulence preventing device 10, so that a good print on the printing paper Is done.
한편, 드럼(9)이 도시한 역방향, 즉 시계방향으로 회전하여도 상기와 같은 난류의 차단효과는 동일하게 이루어진다.On the other hand, even when the drum 9 rotates in the reverse direction, that is, clockwise, as shown, the above-described turbulence blocking effect is achieved.
따라서 상기와 같은 본 고안은 미스트가이드(8)와 드럼(9)사이에 난류방지구 (10)를 설치한 간단한 구조에 의하여 제2도에 도시한 종래의 잉크제트 프린터와 같이, 드럼(9)상의 인자용지에 인자되는 잉크입자(5)의 이동경로가 유동난류에 의하여 그 이동경로가 휘어지는 현상을 방지하지 못하므로 인자의 상태가 불량해지는 결함을 방지하게 됨으로써, 노즐(4)로부터 분사된 잉크입자(5)의 이동경로를 일정하게 유지하여 인자되는 잉크의 위치를 정확하게 제어할 수 있으므로 인자상태를 양호하게하는 이점이 있다.Therefore, the present invention as described above, such as the conventional inkjet printer shown in Figure 2 by the simple structure provided with a turbulence prevention device 10 between the mist guide (8) and the drum (9), the drum (9) Since the movement path of the ink particles 5 printed on the printing paper on the image does not prevent the movement path from being bent due to the flow turbulence, the defect of the printing state is prevented, thereby preventing the ink ejected from the nozzle 4. Since the position of the ink to be printed can be precisely controlled by keeping the movement path of the particles 5 constant, there is an advantage of improving the printing state.
