Is arranged.
상기 압출스크류(40,50)는, 일단부가 기어박스(80)측에 설치된 베어링(82)에 회전자재되게 설치되어 있고, 타단부가 압출배럴(30)에 회전가능하게 지지되어 있고, 상기 기어박스(80)내에는 상기 압출스크류(40,50)에 각각 고정되고 같은 잇수를 갖는 한쌍의 기어(G1,G2)가 이맞물림되어 있고, 상기 압출스크류(40,50)의 플라이트(42,52)가 압출배럴(30)의 압출챔버(32)내에 위치하고 있고, 상기 압출배럴 (30)의 양측벽에는 압출챔버(32)내로 열원을 투입하기 위한 히터(90)가 장착되어 있다.The extruded screws 40 and 50 are rotatably installed at one end of the bearing 82 provided on the gearbox 80 side, and the other end thereof is rotatably supported by the extrusion barrel 30. In the box 80, a pair of gears G1 and G2 fixed to the extruded screws 40 and 50 and having the same number of teeth are engaged with each other, and the flights 42 and 52 of the extruded screws 40 and 50 are engaged. ) Is located in the extrusion chamber 32 of the extrusion barrel 30, and both sides of the extrusion barrel 30 are equipped with a heater 90 for introducing a heat source into the extrusion chamber 32.
이때 상기 압출스크류(40,50)는 상기 압출배럴(30)내에서 수지물의 배압을 높이기 위해 골경의 변화 즉, 압축비의 변화를 갖도록 하기 위해 서로 다른 골경(d1,d2)을 갖되 d1이 d2의 직경보다 크게 설정되어 있다.At this time, the extrusion screw (40, 50) has a different bone diameter (d1, d2) to have a change in the bone diameter, that is, a change in the compression ratio to increase the back pressure of the resin in the extrusion barrel 30, d1 is d2 of It is set larger than the diameter.
또, 상기 압출스크류(40,50)내에는 외부로부터 스팀 등의 열원을 투입하기 위한 열원공급통로(40a,50a)가 구비되어 있고, 이 열원공급통로(40a,50a)측에는 각각 로테이트 조인트(J1,J2)가 설치되어 있다.The extruded screws 40 and 50 are provided with heat source supply passages 40a and 50a for injecting a heat source such as steam from the outside, and each of the rotate joints J1 is provided on the heat source supply passages 40a and 50a.

그리고 상기 압출배럴(30)은 상방으로 수지투입구(32a)를 갖고, 이 수지투입구(32a)의 상면에는 호퍼(34)가 장착되어 있고, 상기 압출챔버(32)의 일측벽 2개소 즉, 압출스크류(40,50)의 각 축선상을 중심으로 하여 원주방향에 다수의 수지배출공(32b)이 형성되어 있다.(도3 참조)The extrusion barrel 30 has a resin inlet 32a upward, and a hopper 34 is mounted on an upper surface of the resin inlet 32a, namely, two locations on one side wall of the extrusion chamber 32, that is, extrusion. A plurality of resin discharge holes 32b are formed in the circumferential direction around the axis lines of the screws 40 and 50 (see Fig. 3).
상기 압출스크류(40,50)에는 상기 압출배럴(30)의 수지배출공(32b)을 통해 뽑아지는 수지물을 작은 알갱이로 절단하기 위해 절단커터(60,70)가 각각 직결되어 있다.Cutting extruders (40, 50) are directly connected to the cutting cutters (60, 70) to cut the resin material drawn through the resin discharge hole (32b) of the extrusion barrel 30 into small grains, respectively.
미설명 부호 5는 알갱이 받이대이고, 8은 감속기(25)의 출력을 하나의 압출스크류(40)에 전달하기 위한 체인커플링이다.Reference numeral 5 denotes a pellet base, and 8 denotes a chain coupling for transmitting the output of the reducer 25 to one extrusion screw 40.
이와 같이 구성된 본 실시예의 작동상태를 설명한다.The operating state of this embodiment configured as described above will be described.
먼저, 본 발명은 상기 압출배럴(30)과 압출스크류(40,50)를 소정의 온도로 가열시킨 상태에서 압출작업이 진행된다.First, the present invention is the extrusion operation in the state in which the extrusion barrel 30 and the extrusion screw (40, 50) is heated to a predetermined temperature.
이를 위해 압출배럴(30)에 장착된 히터(90)를 가열시키고 동시에 압출스크류 (40,50)의 열원공급통로(40a,50a)로 열원(스팀)을 순환시킨다.To this end, the heater 90 mounted on the extrusion barrel 30 is heated, and at the same time, the heat source (steam) is circulated to the heat source supply passages 40a and 50a of the extrusion screws 40 and 50.
이때 히터(90) 및 압출스크류(40,50)의 온도조절은 도시안된 메인컨트롤러에 의해 제어된다.At this time, the temperature control of the heater 90 and the extrusion screw (40, 50) is controlled by a main controller (not shown).
이같은 상태에서 구동모터(20)를 구동시키면, 감속기(25)의 출력단에 직결된 압출스크류(40)와, 이 압출스크류(40)와 기어(G1,G2)의 이맞물림에 의해 연결된 압출스크류(50)가 서로 다른 반대방향으로 회전하고, 이때 압출스크류(40,50)의 회전속도는 동일하고, 이때 압출스크류(40,50)에 각각 직결된 절단커터(60,70)도 원주방향으로 배치된 수지배출공(32b)을 따라 회전한다.When the driving motor 20 is driven in such a state, the extrusion screw 40 directly connected to the output end of the reduction gear 25 and the extrusion screw connected by engagement of the extrusion screw 40 and the gears G1 and G2 ( 50 is rotated in the opposite direction, the rotation speed of the extrusion screw (40, 50) is the same, and in this case also the cutting cutters (60, 70) directly connected to the extrusion screw (40, 50) are also arranged in the circumferential direction It rotates along the resin discharge hole 32b.
따라서 호퍼(34)를 통해 발포 수지를 압출배럴(30)내로 투입하게 되면, 압출챔버(32)측 내벽 및 압출스크류(40,50)의 표면에서 발생되는 열로 인해 발포수지가 반죽상태로 가소화(可塑化)되고, 동시에 압출스크류(40,50)의 회전 구동에 의해 압출배럴(30)에 투입된 발포수지가 반죽상태로 가압되어 수지배출공(32b)을 통해 실가닥으로 배출되고, 수지배출공(32b)을 선회하는 절단커터(60,70)의 절단력에 의해 발포수지는 작은 알갱이로 절단되는 것이다.Therefore, when the foamed resin is introduced into the extrusion barrel 30 through the hopper 34, the foamed resin is plasticized into a dough state due to the heat generated from the inner wall of the extrusion chamber 32 and the surface of the extrusion screws 40 and 50. At the same time, the foamed resin injected into the extrusion barrel 30 by the rotary drive of the extrusion screws 40 and 50 is pressed into the dough state and discharged into the thread strand through the resin discharge hole 32b, and the resin is discharged. The foamed resin is cut into small grains by the cutting force of the cutting cutters 60 and 70 turning the ball 32b.
이때 알갱이의 길이는 절단커터(60,70)의 회전속도에 비례하여 짧아진다.At this time, the length of the grain is shortened in proportion to the rotational speed of the cutting cutter (60, 70).
이와 같이 작동하는 본 발명은 한쌍의 압출스크류(40,50)를 이용한 이축압출방식으로 시간단 생산량이 높아진다.The present invention operating in this way is a biaxial extrusion method using a pair of extruded screws (40, 50), the production time is increased.
또, 압축비가 우수하여 타기종의 기계보다 압출스크류(40,50)의 길이가 짧아 설치면적을 작게 차지하고, 장치의 콤팩트화가 가능하며, 절단커터(60,70)가 압출스크류(40,50)측에 일체화되어 작동하는 방법이므로 절단장치가 간단해진다.In addition, the compression screw is excellent, the length of the extruded screw (40, 50) is shorter than other machines, occupies a small installation area, the device can be compact, the cutting cutter (60, 70) is extruded screw (40, 50) The cutting device is simplified because it is a method of operation integrated with the side.
상술한 바와 같이 본 발명에 의하면, 이축압축방식으로 단위 시간당 생산량을 높일 수 있고, 절단장치를 일체화시켜 장치의 콤팩트화를 꾀할 수 있는 등의 장점을 갖는다.As described above, according to the present invention, it is possible to increase the output per unit time by a biaxial compression method, and to integrate the cutting device to achieve compactness of the device.
