본 발명은 에어제트직기용 서브노즐의 분사구멍에 관한 것으로, 더 상세하게 는 분사구멍의 구조를 개선하여 공기의 분사량과 분사속도를 크게 향상시킬 수 있도록 하고, 또한 이를 통해 공기의 흐름을 향상시켜 서브노즐의 성능을 높일 수 있도록 한 에어제트직기용 서브노즐 및 그 서브노즐의 분사구멍 가공방법에 관한 것이다.The present invention relates to an injection hole of a sub-nozzle for an air jet loom, and more particularly, to improve the structure of the injection hole to greatly improve the injection amount and the injection speed of the air, thereby improving the flow of air. The present invention relates to a subjet for an air jet loom and a spray hole processing method for the subnozzle, which can improve the performance of the subnozzle.

일반적으로 에어제트직기에는 위사삽입노즐에서 발사된 위사가 경사개구에 위입하는 공기안내채널을 따라 복수의 서브노즐이 설치되어 있으며, 서브노즐은 공기안내채널을 향하여 비스듬하게 보조공기를 방출하도록 기능해서 공기안내채널을 관통하는 공기흐름을 향상시켜 위입된 위사에 위사피킹보조력을 제공한다.In general, the air jet loom is provided with a plurality of sub-nozzles along the air guide channel through which the weft fired from the weft insertion nozzle enters the inclined opening, and the sub nozzle functions to discharge auxiliary air obliquely toward the air guide channel. It improves the air flow through the air guide channel to provide weft picking assistance to the encased weft.

이러한 에어제트직기용 서브노즐에는 공기안내채널을 향해 보조공기를 방출하는 분사구멍이 형성되고, 이러한 에어제트직기용 서브노즐에 있어서는 분사구멍으로 분사되는 공기의 분사속도를 향상시키는 것이 중요하다.The air jet loom subnozzle is provided with an injection hole for releasing auxiliary air toward the air guide channel, and in such an air jet loom subnozzle, it is important to improve the injection speed of the air injected into the injection hole.

그러나 도 1과 도 2에 도시된 바와 같이 종래 에어제트직기용 서브노즐(1)의 분사구멍(2)에 있어서는, 입구(2a)의 직경과 출구(2b)의 직경이 동일한 크기로 형성되었기 때문에 구조적으로 공기에 대한 유로저항이 커 공기의 분사량과 분사속도가 저하되는 문제점이 있었으며, 또한 이로 인해 결과적으로 공기의 흐름이 저하되어 서브노즐(1)의 성능이 떨어지게 되는 문제점이 있었다.1 and 2, however, in the injection hole 2 of the conventional subjet nozzle 1 for air jet loom, the diameter of the inlet 2a and the diameter of the outlet 2b are formed in the same size. There is a problem that the flow resistance to the air is structurally large, the injection amount and the injection speed of the air is lowered, and as a result, there is a problem that the air flow is lowered resulting in a decrease in the performance of the sub-nozzle (1).

본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 발명한 것으로, 분사구멍의 구조를 개선하여 공기의 분사량과 분사속도를 크게 향상시킬 수 있도록 하고, 또한 이를 통해 공기의 흐름을 효과적으로 향상시켜 서브노즐의 성능 을 높일 수 있도록 한 에어제트직기용 서브노즐 및 그 서브노즐의 분사구멍 가공방법을 제공하는데 있다.An object of the present invention is to invent the conventional drawbacks as described above, by improving the structure of the injection hole to greatly improve the injection amount and injection speed of the air, and through this effectively improve the flow of air The present invention provides a subjet for an air jet loom and a jetting hole processing method of the subnozzle to improve the performance of the subnozzle.

상기 목적을 달성하기 위해 본 발명의 서브노즐에서는 분사구멍에 중앙부에서 입구측으로 직경이 커지는 테이퍼를 형성하여, 이 테이퍼에 의해 공기의 분사속도가 향상되도록 한 것이다.In order to achieve the above object, in the sub-nozzle of the present invention, a taper having a larger diameter from the center portion to the inlet side is formed in the injection hole so that the injection speed of air is improved by the taper.

상기 목적을 달성하기 위해 본 발명의 가공방법에서는 구멍가공날과 테이퍼가공날을 구비하는 드릴로 서브노즐에 분사구멍을 가공하고, 상기 분사구멍의 중앙부와 입구가 테이퍼가공날에 위치하도록 서브노즐을 하강시키고, 상기 분사구멍이 테이퍼가공날을 따라 회전하도록 서브노즐을 이동시켜 분사구멍에 중앙부에서 입구측으로 직경이 커지는 테이퍼를 가공한 것이다.In order to achieve the above object, in the processing method of the present invention, the injection hole is machined into the subnozzle by a drill having a hole processing blade and a taper processing blade, and the subnozzle is positioned so that the center portion and the inlet of the injection hole are located on the tapered processing blade. The sub-nozzle is moved so that the injection hole rotates along the taper cutting blade, and the taper is formed to increase in diameter from the center portion to the inlet side of the injection hole.

이하 첨부된 도면에 따라서 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.

Since the diameter of the inlet is larger than the diameter of the outlet through which the air is discharged, there is an advantage that the flow resistance to the air is small, which can greatly improve the injection amount and the injection speed of the air.

또한 본 발명의 에어제트직기용 서브노즐(10)에 따르면 분사구멍(11)의 입구측에 형성된 테이퍼(12)에 의해 통해 공기의 흐름이 효과적으로 향상되기 때문에 결과적으로 서브노즐(10)의 성능을 한층 더 높일 수 있는 장점이 있다.In addition, according to the air nozzle loom sub-nozzle 10 of the present invention, since the flow of air is effectively improved by the taper 12 formed at the inlet side of the injection hole 11, the performance of the sub-nozzle 10 is consequently improved. There is an advantage that can be further increased.
