Description
본 발명은 폐플라스틱과 폐목재 등의 폐자재를 사용하여 건축자재를 제조하는 장치에 관한 것으로서, 더 자세하게는 폐플라스틱과 폐목재 등의 분쇄물과 열경화성 수지와 열가소성 수지 등을 혼합한 장입물을 1차 압축해주는 컴팩터가 구비되고 상기 장입물로 만들어진 압출재를 냉각시키기 위한 냉각기가 구비된 폐자재를 이용한 건축자재 제조장치에 관한 것이다.The present invention relates to an apparatus for manufacturing building materials using waste materials such as waste plastics and waste wood, and more particularly, to a charge material containing a mixture of a pulverized product such as waste plastic and waste wood and a thermosetting resin and a thermoplastic resin. The present invention relates to a building material manufacturing apparatus using waste materials provided with a compactor for primary compression and having a cooler for cooling the extruded material made of the charge.
일반적으로 플라스틱 등과 같은 합성수지나 합성수지의 혼합물로 이루어진 성형체는 사출이나 압출에 의하여 제조된다.In general, a molded article made of a synthetic resin such as plastic or a mixture of synthetic resins is produced by injection or extrusion.
사출은 주형의 역할을 하는 금속재질의 금형에 형성되어 있는 형틀 내에 플라스틱 등의 용융재 내지는 반용융재를 주입하고 냉각시켜 복잡한 형상의 제품을 주물품과 같이 다량으로 제조하는 방법이며, 압출은 건축자재인 창문 샤시와 같이 일정한 단면 형상을 갖는 제품을, 금형에 형성된 상기 단면 형상과 동일한 형상의 관통공을 통하여 반용융 상태의 합성수지를 밀어내어 길이가 수 미터 내지는 수십미터에 이르는 성형재를 생산하는 방법으로, 창문 샤시는 길이가 긴 상기 성형재를 적절한 길이로 절단하여 조립된다.Injection is a method of manufacturing a large amount of complex shaped products like castings by injecting and cooling molten or semi-melt materials such as plastic into the mold formed in a metal mold serving as a mold. A product having a constant cross-sectional shape, such as a window chassis, which is a material, is pushed through a semi-molten synthetic resin through a through hole having the same shape as the cross-sectional shape formed in a mold to produce a molding material having a length of several meters or several tens of meters. In this way, the window chassis is assembled by cutting the long length of the molding to an appropriate length.
따라서, 형상이 복잡한 일정 크기의 단품이 아닌 단면 형상이 일정한 협폭장척의 재료를 조립하여 사용하는 건축자재의 경우에는 장척물 생산에 편리한 압출 방식에 제조하는 것이 바람직하나, 프라스틱 등의 과립을 반용융 상태에서 압출하는 종래의 제조장치는 스크류식 장치로서, 플라스틱만이 아닌 폐플라스틱과 폐목재 등의 분쇄물과 열경화성 수지와 열가소성 수지 등의 혼합물을 건축자재로 압출하기에는 압출 속도가 느리고 설비의 크기가 대형화 되는 문제가 있다.Therefore, in the case of a building material which is assembled by using a narrow-length material having a constant cross-sectional shape rather than a single piece of a complicated size, it is preferable to manufacture the extrusion material that is convenient for producing long-walled materials. Conventional manufacturing apparatus that extrudes in a state is a screw-type apparatus, and the extrusion speed is slow and the size of equipment is not sufficient to extrude not only plastic but also pulverized materials such as waste plastics and waste wood, and mixtures of thermosetting resin and thermoplastic resin into construction materials. There is a problem of becoming large.
또한, 상기 혼합물의 압출재 표면은 분쇄된 상태에서 압출직전 반용융 상태가 되어 압출된 후 냉각되나, 방음과 단열 성능이 우수해야 하는 건축자재를 위해서는 압출재 내부의 기공 형성을 위하여 용융되지 않는 부분도 공존하게 되는 바, 종래의 스크류식 압출기를 사용할 경우에는 압출재의 내부 충진밀도가 떨어지는 단점이 있으며, 압출 후 압출재의 냉각이 자연 냉각 방식으로 이루어지기 때문에 압출 형상의 변형이 일어나기 쉬운 단점이 있다.In addition, the surface of the extruded material of the mixture is in the crushed state, the semi-melt state immediately before extrusion is extruded and cooled, but also for the building material should be excellent sound insulation and heat insulation performance, the part that does not melt to form pores inside the extruded material coexist. When using a conventional screw extruder, there is a disadvantage in that the internal filling density of the extruded material is lowered, and since the cooling of the extruded material is made by a natural cooling method after extrusion, there is a disadvantage that the deformation of the extruded shape is likely to occur.
이상에서 살펴본 바와 같이, 본 발명은 종래 전축자재 제조 장치의 제반 문제점들을 해결하기 위한 것으로, 압출 속도를 상승시키고 건축자재의 내부 충진밀도를 다양하게 조절할 수 있는 동시에, 장치의 소형화가 가능한 플라스틱 페자재 등을 이용한 건축자개 제조장치를 제공함에 본 발명의 목적이 있다.As described above, the present invention is to solve all the problems of the conventional pre-spinning material manufacturing apparatus, it is possible to increase the extrusion speed and variously control the internal filling density of the building material, and at the same time the plastic waste material capable of miniaturizing the device It is an object of the present invention to provide a building mother-of-pearl manufacturing apparatus using such.

본 발명의 상기 목적은 원료가 장입되는 중통에 구비된 실린더식 컴팩터와 압출 실린더에 의하여 달성된다.The above object of the present invention is achieved by a cylindrical compactor and an extrusion cylinder provided in a barrel in which the raw material is charged.
본 발명의 폐자재를 이용한 건축자재 제조장치는 유압 모터 및 유압 펌프가구비된 압출 실린더와, 원료가 장입되며 컴팩터가 설치된 중통과, 원료 장입구 커버가 부착되고 중통에 장입될 압출 원료가 저장되는 원료 호퍼와, 상기 중통의 일측 선단부에 연결되는 원통형 히터와, 압출 금형과, 원통형 냉각기로 구성된다.The building material manufacturing apparatus using the waste material of the present invention is an extrusion cylinder equipped with a hydraulic motor and a hydraulic pump, a raw material is loaded and a compactor installed with a compactor, and a raw material loading cover is attached and the raw material to be charged into the barrel is stored. And a raw material hopper, a cylindrical heater connected to one end of the barrel, an extrusion die, and a cylindrical cooler.
상기 본 발명의 제조 장치를 구성하는 중요 구성품들의 역할을 살펴보면 다음과 같다.Looking at the role of the important components constituting the manufacturing apparatus of the present invention as follows.
압출 실린더는 중통 내주면의 일측단부에서 타측단부 사이를 중통의 내주면에 밀착된 상태로 전후 왕복운동 함으로써, 중통 내에 장입된 원료를 압출 금형측으로 이송시키는 역할을 한다.The extrusion cylinder serves to transfer the raw material charged in the barrel to the extrusion mold side by reciprocating back and forth in a state in which it is in close contact with the inner circumferential surface of the barrel between one end of the barrel inner peripheral surface and the other end.
컴팩터는 중통에 원료를 장입시 후진되어 중통 내부에 형성되는 원료 장입 공간을 확대시킨 후, 상기 압출 실린더가 압출을 위하여 전진하기전 본래의 위치로 복귀되면서 확대되었던 상기 원료 장입 공간을 축소시킴으로써 중통에 장입된 원료를 압축하게 되어 장입된 원료의 충진 밀도를 높여주는 역할을 한다.The compactor is enlarged when the raw material is charged into the barrel and enlarges the material loading space formed inside the cylinder, and then reduces the material loading space that has been expanded while returning to the original position before advancing the extrusion cylinder for extrusion. Compression of the charged raw material increases the packing density of the charged raw material.
그리고, 중통에 공급되는 원료가 저장되는 호퍼의 하단부와 중통 상면 사이에 밀착 설치되는 상기 원료 주입구 커버는, 실린더에 의하여 중통의 상면과 호퍼 하단면에 상하 양면이 밀착된 상태로 전후 회동 가능하며, 이 회동 시간을 조정함으로써 중통에 장입되는 원료의 양을 조절할 수 있다.In addition, the raw material inlet cover which is installed in close contact between the lower end of the hopper and the upper surface of the barrel in which the raw material supplied to the barrel is stored, can be rotated back and forth in the state in which the upper and lower surfaces are in close contact with the upper surface and the hopper lower surface of the barrel. By adjusting this rotation time, the quantity of the raw material charged to a barrel can be adjusted.
원통형 히터는 상기 중통과 압출 금형 사이에 설치되어 원료에 적절한 열을 가함으로써, 폐플라스틱 등을 압출에 적합한 반용융 상태로 만들어 주는 역할을 하며, 냉각기는 압출 금형을 통과한 압출재를 신속히 냉각시켜 압출 형상이 변형되는 것을 방지하여 주는 역할을 한다.The cylindrical heater is installed between the barrel and the extrusion mold to apply proper heat to the raw material, thereby making the waste plastic and the like in a semi-melt state suitable for extrusion, and the cooler rapidly cools the extruded material passed through the extrusion mold to extrude. It prevents the shape from deforming.
상기 본 발명의 목적과 기술적 구성을 비롯한 그에 따른 작용 효과에 관한 자세한 사항은 본 발명의 바람직한 실시예를 도시하고 있는 도면을 참조한 아래의 설명에 의해 명확하게 이해될 것이다.Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.
도 1에 본 발명의 일실시예인 폐자재를 이용한 건축자재 제조장치의 개략적인 사시도를, 도 2에 단면도를, 도 3에 도 1의 A-A 단면도를 도시하였다.FIG. 1 is a schematic perspective view of a building material manufacturing apparatus using waste materials, which is an embodiment of the present invention.

도시된 바와 같이, 본 발명의 폐자재를 이용한 건축자재 제조장치는, 유압 모터 및 유압 펌프(도면 미도시)가 구비된 압출 실린더(11)와, 외주면 측면 중앙부에 컴팩터(13)가 설치되며 상기 압출 실린더(11)의 실린더 로드(11A)가 전후 작동하는 공간과 원료의 장입 공간인 원통형 중통(12)과, 중통(12) 외주면 상부에 밀착되어 회동 가능한 원료 장입구 커버(14A)가 구비된 원료 호퍼(14)와, 상기 압출 실린더(11)가 설치된 반대측인 중통(12)의 일측 선단면에 중심축이 일치되도록 밀착되는 원통형 히터(15)와, 상기 원통형 히터(15)의 일측 선단면에 중심축이 일치되도록 밀착되는 압출 금형(16)과, 상기 압출 금형(16)의 일측 선단면에 중심축이 일치되도록 밀착되는 냉각기(17)와, 압출 실린더(11)와 원료 장입구 커버(14A) 및 컴팩터(13)를 제어하는 제어반(도면 미도시)으로 구성된다.As shown, the building material manufacturing apparatus using the waste material of the present invention, the extrusion cylinder 11 is provided with a hydraulic motor and a hydraulic pump (not shown), and the compactor 13 is provided in the central portion of the outer peripheral surface side The cylindrical rod 12, which is a space in which the cylinder rod 11A of the extrusion cylinder 11 operates back and forth, and a charging space of the raw material, and a raw material charging cover 14A which is in close contact with the upper portion of the outer circumferential surface of the central cylinder 12 and is rotatable. The raw material hopper 14 and the cylindrical heater 15 which is in close contact with the central axis coinciding with the one end surface of the heavy cylinder 12 on the opposite side where the extrusion cylinder 11 is installed, and one side line of the cylindrical heater 15. Extruded mold 16 which is in close contact with the central axis to match the cross section, the cooler 17 is in close contact with the central axis to match the one end surface of the extrusion die 16, the extrusion cylinder 11 and the raw material charging cover A control panel (not shown) for controlling the 14A and the compactor 13; It is configured.
상기와 같이 구성되는 본 발명의 제조장치가 동작되는 과정을 살펴보면 다음과 같다.Looking at the operation of the manufacturing apparatus of the present invention configured as described above are as follows.
압출 실린더 로드(11A)가 히터(15)가 설치된 반대 방향으로 중통(12) 내에서 후진함과 동시에 컴팩터(13)의 실린더 로드(13A)도 후진하게 되어 중통 내의 원료 장입 공간이 확장된다.The extrusion cylinder rod 11A reverses in the barrel 12 in the opposite direction in which the heater 15 is installed, and at the same time, the cylinder rod 13A of the compactor 13 also moves backward, thereby expanding the raw material charging space in the barrel.
상기 압출 실린더 로드(11A)와 컴팩터 실린더 로드(13A)의 후진이 완료되면, 원료 장입구 커버 실린더(14B)에 의하여 원료 장입구 커버(14A)가 후진하면서 중통의 원료 장입구(12A)가 개방되고, 원료 호퍼(14) 내에 저장된 원료(M)가 중통으로 장입되며, 이때 상기 원료 장입구 커버(14A)의 개방 시간을 제어하여 중통에 장입되는 원료의 양을 조절할 수 있다.When the extrusion cylinder rod 11A and the compactor cylinder rod 13A are reversed, the raw material charging hole 12A is retracted by the raw material charging cover cylinder 14B while the raw material charging cover 14A is reversed. It is opened, and the raw material M stored in the raw material hopper 14 is charged into the barrel, and at this time, the amount of raw material charged into the barrel can be controlled by controlling the opening time of the raw material charging hole cover 14A.
중통에 원료의 장입이 완료되면, 컴팩터 실린더 로드(13A)가 전진하면서 중통의 원료 장입 공간이 축소되어 중통 내에 장입된 원료(M)가 압축 됨으로써, 원료의 충진 밀도가 높게 되고, 상기 컴팩터에 의한 원료의 압축이 완료되면 압출 실린더가 전진하면서 원료의 압출이 진행된다.When the filling of the raw material into the barrel is completed, as the compactor cylinder rod 13A is advanced, the raw material charging space of the barrel is reduced and the raw material M charged into the barrel is compressed, whereby the filling density of the raw material is high, and the compactor After the compression of the raw material by the completion of the extrusion cylinder advances the extrusion of the raw material proceeds.
그리고, 압출 실린더가 전진함에 따라 중통 내에 장입된 원료는 히터(15)의 중공으로 이동하면서 열에 의하여 히터 내주면에 접촉되거나 가까운 곳의 원료는 반용융 상태(L)가 되어 압출 금형을 통과하게 되고, 압출 금형을 통과한 압출재는 냉각기를 통과하면서 압출 형태가 안정되게 된다.Then, as the extrusion cylinder moves forward, the raw material charged into the barrel is moved to the hollow of the heater 15 while the raw material in contact with or near the inner circumferential surface of the heater passes through the extrusion die in a semi-melt state (L), The extrusion material passing through the extrusion die is stabilized in the extrusion form while passing through the cooler.
이때, 상기 히터의 열을 조절하여 압출전 원료의 용융 정도를 제어함으로써 필요로 하는 압출재의 물성을 조정할 수 있으며, 상기 냉각기의 외주면에는 냉각 효율을 최대화 하기 위한 냉각핀과 외부에서 공급되는 냉각수 순한용 입수구(17A)와 출수구(17B)가 구비되어 냉각기의 외주면과 내주면 사이로는 냉각수가 흐르게 된다.At this time, by adjusting the heat of the heater to control the degree of melting of the raw material before extrusion can adjust the physical properties of the required extruded material, the outer circumferential surface of the cooler and the cooling fins supplied from the outside for cooling fins to maximize the cooling efficiency Inlet port 17A and outlet port 17B are provided so that the coolant flows between the outer and inner circumferential surfaces of the cooler.
이상에서 살펴본 바와 같이, 본 발명의 폐자재를 이용한 건축자재 제조장치는 유압 실린더를 이용한 압출 방식을 적용함으로써 압출 생산성을 높일 수 있으며, 압출전 컴팩터에 의한 원료의 압축이 가능하여 충진율이 우수한 건축자재의 제조가 가능한 장점이 있다.As described above, the building material manufacturing apparatus using the waste material of the present invention can increase the extrusion productivity by applying the extrusion method using a hydraulic cylinder, the construction of excellent filling rate by compressing the raw material by the compactor before extrusion There is an advantage that the manufacture of materials is possible.
또한, 원료 장입구 커버의 개폐 시간과 원통형 히터의 열을 조절 함으로써 압출된 건축 자재 내부의 다공도를 다양하게 제어할 수 있기 때문에 다양한 물성의 건축재 생산이 가능하다.In addition, since the porosity of the extruded building material can be controlled in various ways by controlling the opening and closing time of the raw material charging cover and the heat of the cylindrical heater, it is possible to produce building materials of various physical properties.
