Description
본 고안은 프린트 헤드의 노즐 보호장치에 관한 것으로서, 더욱 상세하게는 헤드를 사용하지 않을 때 노즐이 대기중으로 노출되지 않도록 보호캡의 테두리 부분을 보강하여 밀폐성이 증가되도록 함으로써, 노즐의 막힘현상이 감소되는 프린트헤드의 노즐 보호장치에 관한 것이다.The present invention relates to a nozzle protection device of a print head, and more particularly, by reinforcing the edge of the protective cap so that the nozzle is not exposed to the air when the head is not used, the sealing property is increased, thereby reducing the clogging phenomenon of the nozzle. And a nozzle protector for the printhead.
일반적으로 프린트 헤드는 잉크분사방식을 사용하기 때문에 헤드를 사용하지 않을 때 노즐을 밀폐시켜야 된다. 도 1은 종래 노즐 보호장치를 나타낸 단면도 로서, 헤드(1)의 전방에 노즐(2)이 구비되고 스프링(7)에 의해 헤드(1) 쪽으로 가압되는 보호캡(3)이 마련된다. 보호캡(3)은 노즐(2) 쪽으로 개방된 보호실(5)이 내부에 구비되며 보호실(5)의 외주면에는 노즐(2)의 외주연을 감싸는 테두리(4)가 마련된다. 그리고 보호실(5)의 내부에는 분사되는 잉크를 흡수하여 외부로 튕겨지지 않도록 하는 흡수층(6)이 마련된다.In general, the print head uses an ink spray method, so the nozzle should be sealed when the head is not used. 1 is a cross-sectional view showing a conventional nozzle protection device, the nozzle 2 is provided in front of the head 1 is provided with a protective cap (3) which is pressed toward the head (1) by a spring (7). The protective cap 3 is provided with a protective chamber 5 open to the nozzle 2 therein, and an outer circumferential surface of the protective chamber 5 is provided with an edge 4 surrounding the outer circumference of the nozzle 2. And the inside of the protective chamber 5 is provided with an absorbing layer 6 to absorb the ink to be sprayed so as not to be bounced to the outside.
이처럼 구성된 종래의 프린트 헤드(1)는 인쇄하지 않는 동안 보호캡(3)에 의해 노즐(2)이 보호된다. 보호캡(3)은 노즐(2)의 막힘원인이 되는 인크의 건조, 대기중의 먼지 흡입 등을 방지하는 것으로 테두리(4)가 노즐(2)의 외주면과 밀착되면 노즐(2)이 대기중으로 노출되지 않는다.In the conventional print head 1 thus constructed, the nozzle 2 is protected by the protective cap 3 while not printing. The protective cap 3 prevents the drying of the ink, which causes the clogging of the nozzle 2, and the inhalation of dust in the air. When the edge 4 is in close contact with the outer circumferential surface of the nozzle 2, the nozzle 2 is brought into the atmosphere. It is not exposed.
그러나 노즐(2)과 밀착되는 테두리(4)의 접촉면적이 작기 때문에 밀폐성이 저하된다. 또한 노즐(2)의 외주면에 이물질이 부착된 경우 테두리(4)와의 사이에 간격이 벌어져 완전한 밀폐가 이루어지지 않게되어 잉크가 건조되고 또한 노즐의 막힘현상이 발생되는 등의 단점이 있다.However, since the contact area of the edge 4 in close contact with the nozzle 2 is small, the sealing property is lowered. In addition, when foreign matter is attached to the outer circumferential surface of the nozzle 2, the gap between the edge 4 is widened so that the seal is not completely sealed and the ink is dried and clogging of the nozzle occurs.
본 고안은 종래의 문제점을 감안하여 개발한 것으로서, 본 고안의 목적은 노즐을 감싸는 테두리의 접촉면적을 증가시켜 노즐이 완전 밀폐되도록 함으로써, 이물질에 의해 노즐의 막힘현상이 발생되지 않는 프린트 헤드의 노즐 보호장치를 제공함에 있다.The present invention was developed in view of the conventional problem, and an object of the present invention is to increase the contact area of the edge surrounding the nozzle so that the nozzle is completely sealed, so that the nozzle of the print head is not clogged by the foreign matter. To provide protection.

상기 목적을 달성하기 위하여 본 고안은 헤드의 전방에 잉크를 분사하는 노즐이 구비되고 상기 노즐의 외주연을 감싼 상태로 노즐을 보호하는 보호캡이 구비된 프린트 헤드의 노즐 보호장치에 있어서, 상기 보호캡의 선단에 상기 노즐의 외주연을 감싸는 내측부와 외측부가 각각 구비되고 상기 내측부와 외측부의 사이에 공기단열층을 형성하는 공간부가 구비된 특징이 있다.In order to achieve the above object, the present invention is provided with a nozzle for spraying ink in front of the head, the nozzle protection device of the print head provided with a protective cap for protecting the nozzle in a state surrounding the outer periphery of the nozzle, the protection An inner side and an outer side of the cap surrounding the outer periphery of the nozzle are respectively provided, and a space portion is formed between the inner side and the outer side to form an air insulation layer.
이하 본 고안의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안 보호장치의 단면도 로서, 왕복이동되는 헤드(10)가 구비되고 헤드(10)의 전방에 잉크를 분사하는 노즐()이 마련된다. 또한 노즐(11)의 전방에는 노즐(11)을 감싸는 보호캡(12)이 마련된다. 보호캡(12)은 스프링(19)에 의해 헤드(10) 쪽으로 가압되어 노즐(12)이 이물질에 의해 막히는 것을 차단한다. 그리고 보호캡(12)은 노즐(12) 쪽으로 노출된 보호실(13)이 구비되고 내부에는 노즐(11)에서 분사되는 잉크를 흡수하는 흡수층(18)이 마련된다.2 is a cross-sectional view of the protection device of the present invention, the head 10 is provided with a reciprocating movement is provided with a nozzle () for ejecting ink in front of the head (10). In addition, the front of the nozzle 11 is provided with a protective cap 12 surrounding the nozzle (11). The protective cap 12 is pressed toward the head 10 by the spring 19 to block the nozzle 12 from being blocked by foreign matter. In addition, the protective cap 12 includes a protective chamber 13 exposed toward the nozzle 12, and an absorption layer 18 for absorbing ink sprayed from the nozzle 11 is provided therein.
또한 보호캡(12)에는 보호실()의 개방쪽에 사방으로 테두리()가 구비된다. 테두리(14)는 노즐(11)의 외주연과 접촉되어 노즐()을 밀폐시키는 것으로 테두리(14)는 내측부(15)와 외측부(16)의 2중으로 구성된다. 그리고 내,외측부(15)(16)는 양측으로 갈라져 서로 떨어지도록 구성되고 이들 사이에는 공간부(13)가 마련된다.In addition, the protective cap 12 is provided with a border () in all directions on the open side of the protective chamber (). The edge 14 is in contact with the outer periphery of the nozzle 11 to seal the nozzles. The edge 14 is composed of a double of the inner part 15 and the outer part 16. The inner and outer portions 15 and 16 are divided to both sides and separated from each other, and a space 13 is provided therebetween.
이처럼 구성된 본 고안은 보호캡(12)이 헤드(10)와 밀착되면 노즐(11)의 외주연이 테두리(14)에 의해 밀폐된다. 테두리(14)는 내측부(15)와 외측부(16)로 갈라져 구성됨으로 이들 각 내,외측부(15)(16)가 노즐(11)의 외주연과 밀착되면 접촉면적이 증가되어 밀폐성이 증가된다. 그리고 내,외측부(15)(16)의 사이에 공간부(13)가 구비됨으로 공기단열의 효과가 있어 노즐(11)의 건조가 방지된다.When the protective cap 12 is in close contact with the head 10, the present invention configured as described above is closed by the edge 14 of the outer circumference of the nozzle 11. The edge 14 is divided into the inner part 15 and the outer part 16, so that when each of the inner and outer parts 15 and 16 is in close contact with the outer circumference of the nozzle 11, the contact area is increased to increase the sealing property. In addition, since the space 13 is provided between the inner and outer portions 15 and 16, air insulation is prevented, and drying of the nozzle 11 is prevented.
이상에서와 같이 본 고안에 따르면 헤드의 전방에 밀착되는 보호캡의 테두리가 내측부와 외측부로 갈라져 구성됨으로 접촉면적이 증가되어 노즐의 밀폐성이 향상된다. 그리고 내측부와 외측부의 사이에 공간부가 형성되어 노즐을 단열시키는 역할을 함으로 잉크가 쉽게 건조되지 않아 노즐의 막힘현상이 감소되는 등의 효과가 있다.As described above, according to the present invention, the edge of the protective cap in close contact with the front of the head is divided into an inner side and an outer side, thereby increasing the contact area, thereby improving the sealing property of the nozzle. In addition, since a space is formed between the inner part and the outer part to insulate the nozzle, ink is not easily dried, and thus clogging of the nozzle is reduced.
