도 1은 본 발명의 실시예에 따른 단면도이고, 도 2는 본 발명의 실시예에 따른 요부확대도를 각각 도시한 것으로서, 이하 첨부되는 도면을 참조하여 본 발명을 설명하면 다음과 같다.1 is a cross-sectional view according to an embodiment of the present invention, Figure 2 is an enlarged view of the main portion according to an embodiment of the present invention, respectively, with reference to the accompanying drawings as follows.

본 발명은 도 1, 2에 도시된 바와 같이 몸체(10)와, 액체원료(21)를 공급하기 위해 상기 몸체(10) 선단 일측에 설치되는 액체원료 공급실린더(20)로 구성되는 종래의 우레탄 고압 발포기 헤드에 있어서,The present invention is a conventional urethane composed of a liquid raw material supply cylinder 20 is installed on one side of the body 10, the front end of the body 10 to supply the liquid raw material 21, as shown in Figs. In the high pressure foamer head,

상기 몸체(10) 내부에 고체원료(31)를 공급하기 위한 고체원료 공급실린더(30)가 설치됨을 특징으로 한다.It is characterized in that the solid raw material supply cylinder 30 for supplying the solid raw material 31 in the body 10 is installed.

상기 고체원료 공급실린더(30)는, 몸체(10) 내부에 설치되는 것으로서, 내부는 고체원료(31)의 공급이 원활하게 이루어지도록 속이 빈 형태로 구성되며, 선단은 액체원료 공급실린더(20) 선단 사이에 위치된다.The solid raw material supply cylinder 30, which is installed in the body 10, the inside is configured in a hollow form so that the supply of the solid raw material 31 is smooth, the tip is a liquid raw material supply cylinder (20) It is located between the tips.

그리고 고체원료 공급실린더(30)의 후단은, 몸체(10) 내부로부터 돌출되며 미네랄 등의 고체원료(31)를 공급하는 주름관(40)과 연결설치된다.And the rear end of the solid raw material supply cylinder 30, protrudes from the inside of the body 10 is connected to the corrugated pipe 40 for supplying a solid raw material 31, such as minerals.

또한, 고체원료 공급실린더(30) 후단 일측에는 펌프 등의 장치와 연결되어 고체원료 공급실린더(30) 내부로 압축공기를 불어넣을 수 있도록 고체원료 공급실 린더(30) 내부와 연통되는 압축공기 공급부(32)가 천공된다.In addition, a compressed air supply unit connected to an apparatus such as a pump at one end of the solid material supply cylinder 30 to communicate with the inside of the solid material supply cylinder 30 so as to blow compressed air into the solid material supply cylinder 30 ( 32) is perforated.

이때, 압축공기 공급부(32)에 공급되는 압축공기와 주름관(40)에서 공급되는 고체원료(31)가 직각으로 맞부딪칠 경우 고체원료(31)의 원활한 공급에 방해를 줄 수 있으므로 이를 방지하기 위해 고체원료 공급실린더(30) 후단 내부에 압축공기와 고체원료(31)를 격리하는 격벽(33)이 설치된다.In this case, when the compressed air supplied to the compressed air supply unit 32 and the solid raw material 31 supplied from the corrugated pipe 40 collide at a right angle, they may interfere with the smooth supply of the solid raw material 31 to prevent this. The partition 33 which isolates the compressed air and the solid raw material 31 is installed in the rear end of the solid raw material supply cylinder 30.

그리고 고체원료 공급실린더(30)의 후단과 연결되는 주름관(40) 내부에는 스프링(50)을 설치하여 스프링(50)의 회전에 의해 고체원료(31)의 공급량을 조절할 수 있도록 한다.And the inside of the corrugated pipe 40 connected to the rear end of the solid raw material supply cylinder 30 is installed a spring 50 to adjust the supply amount of the solid raw material 31 by the rotation of the spring (50).

한편, 액체원료 공급실린더(20)는 고체원료 공급실린더(30)와 70°이하의 예각으로 이루며, 고체원료 공급실린더(30) 선단에는 역류 방지턱(34)이 마련되어 있기 때문에 액체원료(21)가 고체원료 공급실린더(30) 측으로 역류하는 것을 방지할 수 있다.Meanwhile, the liquid raw material supply cylinder 20 is formed at an acute angle of 70 ° or less with the solid raw material supply cylinder 30, and the liquid raw material 21 is formed because the backflow prevention jaw 34 is provided at the tip of the solid raw material supply cylinder 30. Backflow to the solid raw material supply cylinder 30 side can be prevented.

즉, 액체원료 공급실린더(20)가 일정각도로 기울어져 있기 때문에 액체원료(21) 또한 기울어진 상태로 분사되므로 액체원료(21)가 고체원료 공급실린더(30) 측으로 역류하는 것을 방지할 수 있으며, 또한 액체원료 공급실린더(20)에서 액체원료(21)가 분사되면 고체원료 공급실린더(30)에 형성된 역류 방지턱(34)과 접촉을 이루면서 역류 방지턱(34)을 따라 앞쪽 방향으로 이동하기 때문에 고체원료 공급실린더(30) 측으로 역류하는 것을 완벽히 방지할 수 있다.That is, since the liquid raw material supply cylinder 20 is inclined at a predetermined angle, the liquid raw material 21 is also injected in an inclined state, so that the liquid raw material 21 may be prevented from flowing back to the solid raw material supply cylinder 30. Also, when the liquid raw material 21 is injected from the liquid raw material supply cylinder 20, the solid raw material moves in the forward direction along the non-return bump 34 while making contact with the backflow preventer 34 formed in the solid raw material supply cylinder 30. Backflow to the raw material supply cylinder 30 side can be completely prevented.
