Description

워터제트직기용 분사노즐{INJECTION NOZZLE FOR WATER JET LOOM}Jet nozzle for water jet looms {INJECTION NOZZLE FOR WATER JET LOOM}

본 고안은 분사되는 분사수가 정류 및 집속된 상태에서 위입될 수 있도록 구조가 개량된 워터제트직기용 분사노즐에 관한 것이다.
The present invention relates to a jet nozzle for water jet looms with an improved structure so that the jetted water to be injected in the rectified and focused state.

일반적으로 워터제트직기는 분사노즐을 통하여 분사수를 분사하면서 위사를 개구된 경사 사이로 위입되게 하고, 이때 분사수는 매우 빠른 초고속으로 분사작업이 이루어지도록 하고 있다.In general, a water jet loom allows the weft to enter between the inclined openings while spraying the jetting water through the jetting nozzle, and the jetting water is sprayed at a very high speed.

그러나 분사노즐로 공급되는 고압분사수는 분사노즐의 본체 측면에 뚫린 여러개의 주입공을 통하여 분사노즐내로 유입된 다음 니들에 부딪혀 방향을 바꾸어 고압에 의해 전방에 분사되므로 분사노즐내로 유입된 분사수는 와류현상과 함께 집속력을 상실하게 되고, 이러한 상태에서 분사수가 위사를 물고 개구된 경사 사이로 위입하게 됨에 따라 불안정한 분사수의 공급으로 셩사를 간섭하게 되므로 장력불균일로 인한 제직불량의 원인이 되고 있는 것이다.However, the high pressure jet water supplied to the jet nozzle flows into the jet nozzle through several injection holes drilled in the main body side of the jet nozzle, and then hits the needle to change direction and is jetted forward by high pressure. The focusing power is lost together with the vortex phenomenon, and in this state, as the injection water enters between the inclined openings and wefts, the yarn is interfered by the supply of unstable injection water, which causes the weaving defect due to the tension unevenness. .

이러한 문제점을 시정하기 위한 종래기술의 일예로 원통형의 본체 내에 방사상 형태의 내면돌출편들을 갖는 정류자를 분사노즐의 본체 내면 주입공 전면에 결합하여 고압분사수가 니들에 부딪혀 와류현상에 의해 분산되는 것을 완화시켜 분사수가 집속성을 갖도록 하여 위사의 공급이 다소 원활하게 이루어지도록 하였다.As an example of the prior art for correcting this problem, a commutator having radially shaped inner protruding pieces in a cylindrical body is coupled to the front surface of the injection hole of the main body of the injection nozzle to mitigate the dispersion of high-pressure jets by needles and vortices. The sprayed water has a focusing property so that the supply of the weft is made smoothly.

이러한 구성의 정류자를 분사노즐에 결합하여 사용함으로써 분사수의 집속성을 증가시켜 위사의 공급시의 문제점을 어느 정도 해결할 것이나 점차 고속화되어가는 직기산업에 비추어 볼 때 정류자는 아직 많은 문제점을 내포하고 있다.
By using the commutator of this configuration in combination with the injection nozzle, the concentration of the injection water will be increased to solve the problem of supplying the weft to some extent, but the commutator still has many problems in light of the increasingly fast loom industry. .

따라서 본 고안의 목적은 분사노즐을 통하여 분사되는 정류 및 집속성을 보다 향상시켜 수렴분사통로의 테이퍼면 손상 및 장력불균일로 인한 제직불량현상을 방지할 수 있는 워터제트직기용 분사노즐을 제공함에 있다.
Accordingly, an object of the present invention is to provide a jet nozzle for water jet looms which can prevent the weaving defects caused by the tapered surface damage and the tension irregularity of the converging injection path by further improving the rectification and focusing characteristics injected through the injection nozzle. .

상기의 목적을 달성하기 위한 본 고안은, 워터제트직기용 분사노즐에 있어서, 관형본체(4)의 입수공(32)과 연통된 실장부(12)에 정류자(14)를 설치하고, 후방 손잡이(22)와 전방 침상단부(10)를 갖는 니들(6)을 실장부(12)에 삽입하여 침상단부(10)가 정류자(14)에 끼워지게 나사 결합하며, 관형본체(4) 후미측에 형성된 분사유도공(34)에는 테이퍼면(18a)이 있는 수렴분사통로(18)를 갖는 분사안내구(16)가 나사결합되게 구성하되, 상기 분사안내구(16)는 스테인레스 재질의 금속재, 세라믹 중 어느 하나로 형성하며, 분사안내구(16)의 후미 출구에는 세라믹, 초경합금 중 어느 하나로 형성된 내마모성 링부재(20)를 분사안내구(16)의 후미에 결합구성하여서 고압분사수와 함께 분사되는 위사로부터 분사안내구(16)가 보호되게 함을 특징으로 한다.
