종래의 압출기는 도 1과 같이 투입구가 구비된 실린더(1)와 상기 실린더 내측에 스크류(2)가 형성되어 실린더로부터 투입되는 폴리에틸렌 파쇄물을 용융하여 이송시키도록 구성되어 있으나, 이는 스크류(2)에 회전축(20a)이 일정하게 평형으로 형성되어 압출부측으로 이송시키는 가압력이 낮아 용융물의 역류 및 압출량이 저하되고, 또한 혼렌 및 믹싱되는 밀도가 낮아 재생되는 폴리에틸렌의 품질이 떨어지며 문제점이 있었다Conventional extruder is configured to melt and convey the polyethylene (1) is injected from the cylinder is formed with a cylinder (1) and a screw (2) inside the cylinder as shown in FIG. The rotating shaft 20a is formed in a constant equilibrium, and the pressing force to be transferred to the extrusion part is low, so that the reverse flow and extrusion amount of the melt are lowered, and the blended and mixed densities are low, thereby reducing the quality of the recycled polyethylene.
이에 본 고안은 상기와 같은 종래의 문제점을 해소하고자 안출된 것으로, 스크류의 이송력을 높이고 혼렌 및 믹싱되는 혼합률을 높힐수 있게 한 것인데, 이를 첨부된 도면에 의거 보다 상세하게 설명하면 다음과 같다The present invention is devised to solve the conventional problems as described above, to increase the feed force of the screw and to increase the mixing ratio of the mixed and mixed, which will be described in more detail based on the accompanying drawings as follows.
도 1은 종래의 압출기1 is a conventional extruder
