다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

도 1은 본 발명에 따른 믹싱 노즐의 분해사시도, 도 2는 도 2의 종단면도, 도 3은 본 발명에 따른 믹싱 노즐이 수지액과 안료를 혼합하는 상태를 나타낸 일 예시도이다.1 is an exploded perspective view of a mixing nozzle according to the present invention, FIG. 2 is a longitudinal sectional view of FIG. 2, and FIG. 3 is an exemplary view showing a state in which a mixing nozzle according to the present invention mixes a resin solution and a pigment.

먼저, 본 발명은 도 1 내지 도 2에 도시된 바와 같이, 노즐 본체와, 제1,2혼합통 및 혼합용 볼로 크게 구성된다.First, the present invention is largely composed of a nozzle body, a first and a second mixing cylinder and a mixing ball, as shown in FIGS.

이때, 상기 노즐 본체(100)는 일측에 장축의 분사부(110)가 형성되되, 상기 분사부(110) 내측에는 외측단을 향해 직경이 좁아지는 배출공(111)이 형성되고, 타 측에는 체결부(120)가 형성되되, 상기 체결부(120)의 내측에는 결합공(121)이 형성되어 상기 배출공(111)의 내측부와 결합공(121)의 중앙부가 서로 연통되도록 형성된다.At this time, the nozzle body 100 is formed with an injection unit 110 of a long axis on one side, the discharge hole 111 is formed in the injection unit 110 narrower toward the outer end is formed, the other side is fastened A portion 120 is formed, and the coupling hole 121 is formed inside the fastening portion 120 so that the inner portion of the discharge hole 111 and the central portion of the coupling hole 121 communicate with each other.

또한, 상기 제1혼합통(200)은 상기 노즐 본체의 결합공(121) 내부에 삽입되어 배출공(111) 측 내부 단턱과 맞닿도록 하되, 일측이 개구된 원통으로써, 배출공(111) 측 단부와 맞닿은 격벽(210)에는 다수개의 분사공(211)이 구비되도록 형성된다.In addition, the first mixing cylinder 200 is inserted into the coupling hole 121 of the nozzle body to be in contact with the inner step of the discharge hole 111 side, one side is a cylindrical opening, the discharge hole 111 side The partition wall 210 which is in contact with the end is formed to be provided with a plurality of injection holes 211.

이때, 상기 제2혼합통(300)은 상기 제1혼합통(200)과 대칭되는 형태로 개구된 일측이 먼저 삽입되어 결합공(121) 내부에 수납되도록 하되, 상기 결합공(121)의 외측 단부측으로 향한 벽면(310)에는 다수개의 유입공(311)이 구비되도록 형성된다.At this time, the second mixing cylinder 300 has one side opened in a symmetrical form with the first mixing cylinder 200 is inserted first to be accommodated in the coupling hole 121, the outside of the coupling hole 121 The wall surface 310 toward the end side is formed to be provided with a plurality of inlet holes (311).

이에, 상기 혼합용 볼(400)은 상기 제1혼합통(200)과 제2혼합통(300)의 사이에 수납되어 유입된 수지액과 안료가 와류 또는 회전에 의해 균일하게 혼합되도록 형성된다.Thus, the mixing ball 400 is formed to be uniformly mixed by the vortex or rotation of the resin solution and the pigments received received between the first mixing cylinder 200 and the second mixing cylinder 300.

즉, 본 발명은 도 3에 도시된 바와 같이, 수지액과 안료가 제2혼합통의 유입공으로 인해 내측으로 들어오면 제1,2혼합통 내에 수납된 볼의 회전에 의하여 와류가 발생되어 원활한 색상 혼합을 조장하게 되고, 이후 제1혼합통의 분사공을 통해 상기 혼합된 수지액+안료가 원하는 색상을 연출하며 노즐의 배출공으로 하여금 사출성형을 도모하도록 형성된다.That is, as shown in FIG. 3, when the resin solution and the pigment enter the inner side due to the inflow hole of the second mixture, vortices are generated by the rotation of the balls accommodated in the first and second mixtures. The mixing is facilitated, and then the mixed resin solution + pigment is formed through the injection hole of the first mixing cylinder to produce a desired color, and the discharge hole of the nozzle is formed to achieve injection molding.

이때, 상기 혼합용 볼은 내마모성이 우수한 세라믹 또는 지르코니아 재질의 구형 볼로 형성되는 것이 바람직하며, 제1,2혼합통의 내부 직경에 비하여 1/2~2/3 내외의 외경으로 형성되는 것이 바람직하다.In this case, the mixing ball is preferably formed of a spherical ball made of ceramic or zirconia made of excellent wear resistance, it is preferably formed of an outer diameter of about 1/2 to 2/3 outside the inner diameter of the first and second mixing cylinders. .

이는 유입되는 수지액과 안료의 회전 와류시 가장 적합한 혼합을 조장하기 때문이다.This is because it promotes the most suitable mixing during rotational vortex of the incoming resin liquid and pigment.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and those skilled in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
