Losing forms are arranged.

상기 타원링 형상의 유동가이드(300)는 그 양단이 상술한 분배관(200)의 일단에 연결설치되는 노즐고정가이드(100)와 회전가이드(104)의 연결구조와 동일한 방식을 갖고 산세조(4)의 양측 내벽면에 고정된다.The elliptical ring-shaped flow guide 300 has the same method as the connection structure of the nozzle fixing guide 100 and the rotation guide 104, both ends of which are connected to one end of the distribution pipe 200 described above, and the pickling tank ( It is fixed to the inner wall surface of both sides of 4).

뿐만 아니라, 상기 유동가이드(300)의 내주면에는 래크(310)가 형성되고, 상기 래크(310)의 하측에는 상기 산세노즐(220)의 위치에 대응되게 다수의 안내돌기(320)가 돌출형성된다.In addition, a rack 310 is formed on an inner circumferential surface of the flow guide 300, and a plurality of guide protrusions 320 protrude from the bottom of the rack 310 to correspond to the position of the pickling nozzle 220. .

다른 한편, 상기 유동가이드(300) 내부에는 상기 산세노즐(220)의 위치에 대응되게 다수의 노즐캡(400)이 끼워진다.On the other hand, a plurality of nozzle caps 400 are fitted in the flow guide 300 to correspond to the position of the pickling nozzle 220.

이때, 상기 노즐캡(400)은 대략 원통형상의 부재이며, 그 외주면에는 안내홈(410)이 경사형성되고, 상기 안내홈(410)에는 상기 유동가이드(300)의 내주면에 돌출된 안내돌기(320)가 끼워지며, 그 상단부 외주면에는 피니언(420)이 형성되고, 하단에는 직경방향으로 대응되는 한쌍의 핀(440)이 고정된다.At this time, the nozzle cap 400 is a substantially cylindrical member, the guide groove 410 is inclined on the outer peripheral surface, the guide groove 410 is a guide projection 320 protruding on the inner peripheral surface of the flow guide 300 ) Is fitted, the pinion 420 is formed on the outer peripheral surface of the upper end, a pair of pins 440 corresponding to the radial direction is fixed to the lower end.

특히, 상기 핀(440)은 상기 산세노즐(220)의 하단 구멍 속으로 삽입될 수 있도록 노즐캡(400)의 원중심을 향해 연장된 다음 다시 상방향으로 절곡되는 형태로 구성된다.In particular, the pin 440 extends toward the center of the nozzle cap 400 so that the pin 440 can be inserted into the bottom hole of the pickling nozzle 220, and is bent upwardly again.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

분배관(200)으로 산세를 위한 세척액이 공급됨과 동시에 구동모터(120)가 구동된다.The washing motor for pickling is supplied to the distribution pipe 200 and the driving motor 120 is driven at the same time.

이에 따라, 구동모터(120)와 연결된 회전원판(130)이 회전되게 되고, 상기 회전원판(130)내 캠기어(134)에 맞물린 유성기어(140)가 회전되면서 상기 분배관(200)을 대략 타원형상으로 흔들게 된다.Accordingly, the rotation disk 130 connected to the drive motor 120 is rotated, and the planetary gear 140 engaged with the cam gear 134 in the rotation disk 130 rotates to roughly distribute the distribution pipe 200. It will shake in an elliptical shape.

상기 분배관(200)이 유동되게 되면 이와 일체로 고정된 산세노즐(220)도 유 동되게 되고, 동시에 상기 산세노즐(220)의 하단에 걸리는 노즐캡(400)도 동일 방향으로 유동되게 된다.When the distribution pipe 200 is flowed, the pickling nozzle 220 which is fixed integrally therewith is also flowed, and at the same time, the nozzle cap 400 applied to the lower end of the pickling nozzle 220 is also flowed in the same direction.

따라서, 그와 맞물린 래크(310)에 힘이 가해지고, 이는 유동가이드(300)를 상기 분배관(200)과 동일형태로 운동시키게 되며, 또한 래크(310)와 노즐캡(400)에 형성된 피니언(420) 간에는 구속력이 없으므로 상기 노즐캡(400)이 쉽게 회전하게 되고, 이에 따라 노즐캡(400)에 형성된 안내홈(410)이 안내돌기(320)에 구속된 상태로 상승하게 된다.Therefore, a force is applied to the rack 310 engaged therewith, which causes the flow guide 300 to move in the same shape as the distribution pipe 200, and also the pinion formed on the rack 310 and the nozzle cap 400. Since there is no restraint force between the 420, the nozzle cap 400 is easily rotated, and thus the guide groove 410 formed in the nozzle cap 400 is raised in a state constrained by the guide protrusion 320.

결국, 노즐캡(400)의 상승은 그 하단에 고정된 핀(440)이 산세노즐(220)의 노즐 구멍으로 진입되게 안내하게 되고, 이로 인해 노즐 구멍은 상기 핀(440)에 의해 뚫리게 된다.As a result, the rise of the nozzle cap 400 guides the pin 440 fixed at the lower end of the nozzle cap 400 to enter the nozzle hole of the pickling nozzle 220, and thus the nozzle hole is drilled by the pin 440. .

이와 같은 동작이 산세중 지속적으로 수행되므로 산세노즐(220)의 노즐 구멍은 막히지 않게 되고, 따라서 노즐 구멍 막힘에 의한 문제가 해소되게 된다.Since the operation is continuously performed during pickling, the nozzle hole of the pickling nozzle 220 is not clogged, thus eliminating the problem caused by clogging the nozzle hole.

이상에서 상세히 설명한 바와 같이, 본 발명은 산세중 지속적으로 산세노즐의 하단 구멍을 핀으로 뚫어주게 되어 노즐 막힘 현상을 방지하고, 그로 인한 산세불량을 예방하여 제품의 품위를 향상할 뿐만 아니라 작업부하를 경감시키고 생산성 향상에 일조하는 효과를 제공한다.As described in detail above, the present invention is to continuously puncture the lower hole of the pickling nozzle during pickling to prevent nozzle clogging, thereby preventing pickling defects resulting in improved product quality as well as work load It helps to alleviate and help increase productivity.
