Description
본 발명은 플라스틱 압출성형기의 배기식 스크류에 관한 것으로, 보다 상세하게는 압출성형기의 실린더 내부에서 폐플라스틱 합성수지의 재료를 고속작업시 가소화 품질이 좋으면서도 배기 효과가 좋아 생산량을 높이고 여러 종류의 합성수지를 처리할 수 있는 플라스틱 압출성형기의 배기식 스크류에 관한 것이다.The present invention relates to an exhaust screw of a plastic extrusion machine, and more particularly, the plasticization quality of the waste plastic synthetic resin material in the cylinder of the extruder during high-speed operation, while the good plasticizing quality, the production efficiency is good, and the production efficiency is increased, and various kinds of synthetic resins It relates to an exhaust screw of a plastic extrusion machine capable of processing.
일반적으로 산업현장에서 버려지는 폐플라스틱 합성수지는 매립되거나 소각처리되어 주변환경을 오염시키는 원인이 되고 있다. 폐프라스틱 합성수지를 매립할 경우에는 토양중에서 썩거나 분해되지 않아 토양을 황폐화시키고, 이를 소각할 경우에는 각종 유해가스를 방출하게 되어 심각한 대기오염을 유발하는 원인이 된다.In general, waste plastic synthetic resins discarded at industrial sites are buried or incinerated, causing environmental pollution. When the waste plastic synthetic resin is buried, it does not rot or decompose in the soil, and the soil is depleted, and when it is incinerated, it emits various harmful gases, causing serious air pollution.
특히, 최근에는 폐플라스틱 합성수지를 소각하면서 다이옥신이라는 치명적인 독소가 배출되는 것으로 알려짐에 따라 그 대처방안이 시급한 실정이다.In particular, in recent years it is known that the deadly toxin called dioxin is emitted while incineration of waste plastic synthetic resins, and the countermeasures are urgently needed.
이러한 폐플라스틱 합성수지의 적극적인 재활용 처리방안으로 특허출원된(출 원번호:10-2001-21530호) "폐합성수지를 이용한 도관 성형장치"가 알려져 있다.A patent application (application number: 10-2001-21530) for the active recycling of waste plastic synthetic resin is known as a "conduit forming device using waste synthetic resin".
이 폐합성수지를 이용한 도관 성형장치를 이용하면, 산업현장에서 쓸모없이 버려져 환경오염을 유발하는 폐합성수지를 원자재로 이용하므로 환경오염방지는 물론 원자재 구입에 따른 생산비를 대폭 절감할 수 있으며, 대형자재의 성형이 용이하고 전체 생산공정이 자동화되어 생산성을 대폭 향상시킬 수 있는 이점이 있다.By using the conduit forming apparatus using waste synthetic resin, waste synthetic resin is used as raw materials, which is thrown away at industrial sites and causes environmental pollution. Therefore, it is possible to prevent environmental pollution and greatly reduce the production cost due to the purchase of raw materials. There is an advantage that the molding is easy and the entire production process is automated, which can greatly improve the productivity.
상기 폐합성수지를 이용한 도관 성형장치는 산업현장에서 버려지는 폐합성수지를 잘게 분쇄하여 칩형태로 만든 후, 이를 용융시킨 후 압출하여 프레스 성형을 통해 도관을 제조하는 장치이다.The conduit forming apparatus using the waste synthetic resin is a device for producing a conduit through press molding by melting and then extruding the waste synthetic resin finely pulverized into a chip form discarded in an industrial site.
일반적으로 압출성형기의 배기식 스크류는 호퍼를 통해 투입된 열가소성수지를 배럴에 장착된 가열기를 통해 용융하면서 일단부에 형성된 배출구로 강제 압출시키는 기능을 한다.In general, the exhaust screw of the extrusion machine serves to forcibly extrude the thermoplastic resin introduced through the hopper through the heater mounted on the barrel to the outlet formed at one end.
이러한 스크류는 압출기의 배럴 내부에 축설되어 투입되는 열가소성수지를 용융상태에 따라 압송하는데, 이는 스크류에 나선으로 감겨있는 플레이트로 가능하다.Such a screw is pumped according to the molten state of the thermoplastic resin that is built up in the barrel of the extruder according to the molten state, which is possible by a plate wound spirally on the screw.
고분자 물질을 성형하는 방법으로는 압출을 가장 흔하게 사용하는데, 최근들어 화재에 대한 문제와 환경에 대한 문제가 같이 요구되면서 고분자 물질에 산화아연이나 산화 마그네슘등을 다량으로 첨가하게 되었다. 이에 따라 용융수지의 점도가 급격이 증가하여 압출시 고점도에 의한 용융수지의 발열이 증가되고 압출량이 작아지는 단점이 발생되었다.Extrusion is most commonly used as a method of molding a polymer material. Recently, as a fire problem and an environment problem are required, a large amount of zinc oxide or magnesium oxide has been added to the polymer material. As a result, the viscosity of the molten resin is sharply increased, so that the exotherm of the molten resin due to the high viscosity during extrusion is increased and the amount of extrusion is reduced.
특히 고속을 요구하는 압출시에는 이러한 발열 현상이 더욱 증가되어 스크류 의 작업 속도에 제한을 주게 되었다.Particularly during extrusion, which requires high speed, this exothermic phenomenon is further increased, which limits the working speed of the screw.
현재 사용되는 플라스틱 압출성형기의 스크류는 고속운전으로 불량이 많을 뿐만아니라 재료가 넘쳐 배기효과가 털어져 생산량이 줄어들고 여러 종류의 페플라스틱 합성수지를 처리할 수 없게 되어 있었다. The screw of the plastic extrusion machine currently used is not only poor in high speed operation, but also has a lot of materials, and the exhaust effect is reduced, resulting in reduced production and inability to process various kinds of plastic plastic resins.
본 출원인은 플라스틱 압출성형기에 사용되는 스크류를 고속운전시 가소화 품질이 좋으면서도 배기 효과가 좋아 생산량을 높이고 여러 종류의 폐 합성수지를 처리할 수 있는 스크류를 개발한 것이다.The present applicant has developed a screw that can improve the production rate and process various kinds of waste synthetic resins with good plasticizing quality and good exhaust effect at high speed operation of the screw used in the plastic extrusion machine.
본 발명의 목적은 플라스틱 압출성형기에 사용되는 스크류를 고속운전시 가소화 품질이 좋으면서도 배기 효과가 좋아 생산량을 높이고 여러 종류의 폐 합성수지를 처리할 수 있는 플라스틱 압출성형기의 배기식 스크류를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide an exhaust screw of a plastic extrusion machine which can increase the production rate and process various kinds of waste synthetic resins with good plasticizing quality at high speed operation and good exhaust effect. .

본 발명은 폐플라스틱 합성수지가 압출성형기의 호퍼(3) 투입구를 통해 제1단계스크류(A)의 투입구간(A1)에 들어가며, 배기식스크류(1)의 회전으로 폐플라스틱 합성수지가 압축되면서 압축구간(A2)으로 진입하게 된다. 이때 폐플라스틱 합성수지가 압축되면서 점차 융해되기 시작한다. 융해 후에 폐플라스틱 합성수지는 밀려 계량구간(A3)으로 진입하게 되는데 계랑구간(A3)은 주로 페플라스틱 합성수지를 혼합과 절단하여 일정한 양을 혼합구간(A4)로 이송시키며 융해되지 않은 폐플라스틱 합성수지를 먼저 가소화 한다.In the present invention, the waste plastic synthetic resin enters the input section (A1) of the first stage screw (A) through the hopper (3) inlet of the extruder, and the compression section while the waste plastic synthetic resin is compressed by the rotation of the exhaust screw (1) It enters (A2). At this time, the waste plastic synthetic resin begins to melt gradually as it is compressed. After melting, the waste plastic synthetic resin is pushed into the metering section (A3). The stream section (A3) mainly mixes and cuts the plastic plastic resin and transfers a certain amount to the mixing section (A4). Plasticize.
그후, 압력구간(A5)를 통과할 때 실린더에 설치되어 있는 압력조절밸브(5)를 통해 페플라스틱 합성수지의 이송면으로 제2단계스크류(B)의 배기구간(B1)의 폐플라스틱 합성수지의 이송량을 조절하게 되어 배기구간에 진입하는 폐플라스틱 합성수지가 실린더의 배기구로 넘치는 것을 방지한다.Then, when passing through the pressure section A5, the conveyed amount of the waste plastic synthetic resin in the exhaust section B1 of the second stage screw B to the conveying surface of the plastic plastic resin through the
상기 플라스틱 합성수지는 배기구간(B1)에서 수분과 분해물을 배출한 다음 돌변구간(B2)에서 다시 한번 압축되고 계량구간(B3)에서 먼저 혼합, 전단된 후 계랑구간(B3)를 통해 일정한 양과 압력으로 후속 설비에 보내진다.The plastic synthetic resin discharges water and decomposition products in the exhaust section B1, and then is compressed once again in the stone section section B2, mixed and sheared first in the metering section B3, and then at a constant amount and pressure through the girder section B3. It is sent to subsequent equipment.
본 발명은 길이와 직경의 비율이 크기 때문에 고속 작업시에도 폐플라스틱 합성수지의 정체시간이 길어 페플라스틱 합성수지의 가소화가 용이하다.In the present invention, the ratio of length and diameter is large, and thus, even in high-speed operation, the retention time of waste plastic synthetic resin is long, thereby facilitating plasticization of the plastic synthetic resin.
상기 혼합구간(A4)의 구조는 스크류로 하여금 고속작업시 융해되지 않은 폐플라스틱 합성수지를 먼저 혼합하면서 전달하면서 가소화가 용이하다.The structure of the mixing section (A4) is easy to plasticize while the screw is conveyed while mixing the first plastic waste plastic not melted during high-speed operation.
상기 제2단계스크류(B)와 제1단계스크류(A)의 길이 비율에 대한 설계는 폐플라스틱 합성수지의 가소화와 배기효과에 효과적이다.The design of the length ratio of the second stage screw (B) and the first stage screw (A) is effective for plasticizing the waste plastic synthetic resin and exhaust effect.
상기 제2단계스크류(B)의 계량구간(B3)의 길이와 직경의 비율에 대한설계는 앞부분의 압력이 높을 때에도 재료의 역류를 최대한 줄여 생산량에도 증가시킬 수가 있다.The design of the ratio of the length and diameter of the metering section B3 of the second stage screw B can reduce the backflow of the material as much as possible even when the pressure in the front is high, thereby increasing the yield.
상기 압력조절구간(A5)에 설치된 압력조절밸브(5)는 제1단계의 폐플라스틱 합성수지의 압출량을 제2단계에 맞춰 재료가 넘치는 것을 감소시킬 수가 있다.The
본 발명은 고속 작업시 가소화의 품질을 높이면서 생산량을 증가시키며, 폐합성수지인 PE, PP, PET, PS, PC 등으로 적용범위를 넓힐 수가 있는 것이다.The present invention is to increase the production while increasing the quality of plasticization during high-speed operation, it is possible to extend the scope of application to waste plastics PE, PP, PET, PS, PC and the like.
또 플라이트의 높이의 점감 및 점증의 피치를 180°이상으로 설정하여 편심플라이트의 높이 및 조홈의 깊이의 변화를 더욱 완만하게 행하도록 하여도 좋다. The pitch of the flight height and the pitch of the flight may be set to 180 degrees or more so that the change in the height of the eccentric flight and the depth of the jaw groove may be made more smoothly.
