이와 같이된 본 발명은 압출실린더(1)의 내부에 호-스제조용 원료를 넣고 공지의 방법으로 용융시켜 압출스크류(101)로 압출시키면 용융된 수지가 연결관(103)의 압출공(104)을 통해 내통체(2)로 이송되고 배출공(201)에서 환상압출구(203)(204)로 균등히 압출되어 내통체 외주에 장치된 외경다이(5)내면 환상간격(501)으로 충만되고 이 과정에서 내통체(2)표면으로 가설된 내측보강사(11)와 중간보강사(902) 및 외측보강사(112)와 얽히게 되어 보강사가 3층으로 매설된 호-스(12)가 만들어지며 이렇게 만들어진 호-스는 내통체(2)의 공기유입홈(3)에 있는 가열된 공기가 통기공(301)을 통해 압출되는 호-스내로 주입되는 공기의 작용으로 응고가 되고 별도로 장치된 견인장치에 의하여 수평으로 견인되게 된다(이때 견인속도는 압출속도 비슷한 속도로 견인되게 된다).In the present invention as described above, the raw material for manufacturing the hose in the extrusion cylinder (1) is melted by a known method and extruded by the extrusion screw 101, the molten resin is extruded hole 104 of the connecting pipe 103 It is transferred to the inner cylinder (2) through and evenly extruded from the discharge hole (201) to the annular extrusion port (203, 204) and filled with the annular spacing (501) inside the outer diameter die (5) installed on the outer cylinder inner periphery. During the process, the inner reinforcement member (11), which is hypothesized by the inner surface of the inner reinforcement (11) and the intermediate reinforcement (902) and the outer reinforcement (112) is entangled with the reinforcement is made of three layers of hose-hose (12) is made The hose-made so that the heated air in the air inlet groove (3) of the inner cylinder (2) is solidified by the action of the air injected into the hose-extruded through the vent 301, and the traction device is installed separately Is towed horizontally (the towing speed is towed at a speed similar to the extrusion speed).
한편 고정관체(6)표면에 끼워진 푸울리(7)(8)는 서로다른 방향으로 회전되고 푸울리의 회전으로 실꾸리가 공전하면 실구리에 감겨진 보강사(902)(112)가 내통외주에 엇갈려 감기면서 수평으로 공급되는 내측보강사(11) 위에 적층되어 도 4와 같은 형태의 3층 보강사 층을 구성하게 되며 이러한 보강사의 사층은 계속되는 압출작동과 병행하므로 연속하여 보강사가 매설되는 호-스의 제도를 달성하게 된다.On the other hand, the pulleys 7 and 8 fitted on the surface of the fixed tube 6 rotate in different directions, and the reinforcing yarns 902 and 112 wound around the thread are wound around the inner cylinder when the thread is revolved by the rotation of the pulley. Stacked on the inner reinforcement yarn 11 is supplied horizontally while staggering to form a three-layer reinforcement layer of the form as shown in Figure 4 and the four layers of the reinforcement yarn is parallel to the continuous extrusion operation so that the reinforcement is buried continuously- To achieve the system of
그리고 내통체(2)의 끝에 외경다이(205)가 부착되어 내통체(2)의 외경과 단차가 형성되므로 용융수지의 두께를 적절히 유지할 수 있고 보강사를 일정위치에 매설하면서 연속적으로 호-스를 제조할수 있도록 되는 것이며 중심부에서 용융수지가 공급되어 외경다이(5)내면으로 수지를 압출하기 때문에 강한 압력으로 수지를 압출할 수 있고 외경다이(5)의 환상간격(501)에서 출구(502)쪽 내경이 축소되어 있기 대문에 압출되는 호-스의 내부에 들어 있는 기포를 자연스럽게 재거하여 두면서 압출성형이 이루어져 견인되는 호-스의 외벽밀도를 고밀도로 만들수 있으며 호-스 내부로의 공기 공급이 원활하여 응고가 양호하게 되므로 양질의 호-스를 제조할수 있는 장점이 있고 육질이 얇고 가벼워서 농업, 공업용으로 사용하기 좋은 호-스를 제공할수 있는 것이다.And the outer diameter die 205 is attached to the end of the inner cylinder 2 to form a step with the outer diameter of the inner cylinder 2, so that the thickness of the molten resin can be properly maintained and the hose continuously buried in a predetermined position. Since the molten resin is supplied from the center to extrude the resin into the inner diameter of the outer die 5, the resin can be extruded with a strong pressure and the outlet 502 at the annular interval 501 of the outer diameter die 5 is used. Due to the reduced inner diameter, air bubbles inside the extruded hose are naturally removed and extruded to make the outer wall density of the towed hose high density and supply air to the inside of the hose. Smooth and solidification is good, so there is an advantage to produce a good quality hose, the flesh is thin and light, it can provide a good hose for use in agriculture, industry.
