따라서 본 발명에 따라 제조된 비닐봉투는 물, 미생물 및 효소 등의 분해작용에 의해 최종적으로 물, 이산화탄소 및 바이오매스 등으로 완전 생분해가 가능하고, 음이온 및 원적외선 방사 기능에 의한 혈액순환 개선 등의 건강기능성이 뛰어난 효과를 갖을 수 있다.Therefore, the plastic bag manufactured according to the present invention can be completely biodegraded into water, carbon dioxide, and biomass by decomposition of water, microorganisms and enzymes, and health such as improvement of blood circulation by the function of radiation of negative ions and far-infrared rays. It can have an effect with excellent functionality.
본 발명에 따른 비닐봉투를 제조하는 방법은 압출방식이 사용되는 것으로, 압출방식은 용융된 수지를 원형 다이를 통해 튜브형태의 원통형 필름을 상측으로 뽑아올리면서 제조하며, 이때 상기 튜브형태의 원통형 필름의 내부에서는 일정온도와 압력으로 공기를 불어 넣어 주면서 필름의 두께와 생산성 향상을 높일 수 있는데 생산성 향상을 위해 빠른 속도로 뽑아 올리면 튜브형태의 원통형 필름의 표면에 미세한 스크레치가 발생될 수 있다.The method of manufacturing a plastic bag according to the present invention is an extrusion method, and the extrusion method is manufactured by pulling a tube-shaped cylindrical film upward through a circular die of molten resin, and at this time, the tube-shaped cylindrical film The inside of the tube can increase the thickness and productivity of the film while blowing air at a certain temperature and pressure. If it is pulled out at a high speed to improve productivity, a fine scratch may occur on the surface of the tube-shaped cylindrical film.
따라서 일정한 온도와 압력으로 공기를 불어주어야 하고, 상측으로 뽑아 올리는 속도 또한 일정하게 유지되어야 하며, 이를 위하여 튜브형태의 원통형 필름의 인장강도와 치밀도가 유지되어야 하는 것이다.Therefore, air must be blown at a constant temperature and pressure, and the speed of pulling up must be kept constant, and for this, the tensile strength and density of the tube-shaped cylindrical film must be maintained.
즉, 압출에 의한 튜브형태의 원통형 필름의 제조방식은 원형의 다이스에서 인출되는 튜브형태의 원통형 필름은 공기가 주입되면서 폭이 결정되고, 이를 상부로 뽑아올리면서 경화를 위한 냉각을 위하여 일정한 높이의 냉각탑이 구비되고, 상기 냉각탑으로 걸쳐지는 튜브형태의 원통형 필름은 지면에 설치되어있는 권취라인을 통하여 원하는 길이로 권취하게 되는 것이다.In other words, in the manufacturing method of the tube-shaped cylindrical film by extrusion, the width of the tube-shaped cylindrical film drawn out from the circular dies is determined by injecting air, and the width is determined by pulling it up to the top for cooling for curing. A cooling tower is provided, and the tube-shaped cylindrical film spanning the cooling tower is wound to a desired length through a winding line installed on the ground.
상기 압출성형단계에서 원료 용융을 위한 압출기의 배럴내의 온도를 160~200℃로 설정하고, 압출을 위한 스크류 속도는 50~60 rpm을 유지하며, 용융된 원료에서 불순물을 제거하기 위하여 압출기 다이스의 전단에 일체형으로 이루어진 다층 스크린 메쉬를 탈착가능하게 장착하여 압출성형이 이루어지도록 한 것이다.In the extrusion molding step, the temperature in the barrel of the extruder for melting raw materials is set to 160~200℃, the screw speed for extrusion is maintained at 50~60 rpm, and the extruder dies are sheared to remove impurities from the molten raw materials. The multi-layer screen mesh, which is integrally formed with the device, is detachably mounted to allow extrusion molding to be performed.
제조장치로는 비닐봉투원료를 혼합하는 배합기, 배합기에서 배합된 원료의 수분제거를 위한 건조기와 건조기에서 건조된 원료를 호퍼에 공급하고 이를 실린더로 주입시킨 후, 스크류에 의해 성형 금형으로 원료를 공급하는 튜브원료공급장치를 포함한다.The manufacturing equipment includes a blender that mixes raw materials for plastic bags, a dryer for removing moisture from the raw materials blended in the blender, and the raw materials dried in the dryer are supplied to the hopper and injected into the cylinder, and then the raw materials are supplied to the molding mold by means of a screw. It includes a tube raw material supply device.
성형 금형은 원료를 원형 튜브의 형상으로 안내하는 금형(다이)이 설치되며, 튜브를 중앙으로 위치되도록 안내하는 닙롤 및 닙롤을 통과한 원단이 가이드롤러들에 의하여 권취롤러로 안내되어 원단을 감아 보관하게 되며, 권취롤러에 권취되어 제조가 완료된 비닐 원단은 절단기가 설치된 후공정으로 이동되어 지정된 사이즈에 맞추어 재단하고 융착시킨 후 절취 및 펀칭되어 권취되어진 비닐봉투가 제조완료된다.The molding mold is equipped with a mold (die) that guides the raw material in the shape of a circular tube, and the nip roll that guides the tube to be positioned in the center and the fabric that has passed through the nip roll is guided to the take-up roller by the guide rollers, and the fabric is wound and stored. The finished vinyl fabric is wound on the take-up roller and is moved to the post-process where the cutter is installed, cut and fused according to the specified size, and then cut and punched to complete the production of the wound plastic bag.
압출성형단계는 건조된 혼합물을 압출기 호퍼를 통해 공급하여 160 ~ 200℃의 온도의 용융 압출장치에 투입하여 겔형의 액상형태로 용융시킨 압출기 내부에 설치되어있는 스크류에 의해 금형(다이)로 압입된다. 공기주입구로 공기를 주입시키면 맨드릴부에서 용융된 수지가 팽창되어 튜브형태의 원통형 필름으로 연속 성형되면서 상방으로 이동한다. 성형된 필름은 한쌍의 닙롤을 통과하며 통과속도에 따라 압착되어 두께를 조절하고 전면과 후면이 포개진 얇은 두께의 시트 형태로 변형된 다음 다수의 가이드롤러에 의해 이동한다. 이 과정 중 공기에 의해 20 ~ 26℃로 추가 냉각이 되며, 권취롤러로 안내되어 원단을 감아 보관된다. 권취된 비닐원단을 풀면서 일정 간격으로 융착하여 융착선을 형성함과 동시에 상기 융착선과 인접하여 상기 필름을 절단하여 일축이 개방된 사각의 봉투로 가공되며 개봉된 부분을 재단하여 링고리, 양날손잡이, 일반 재단 등의 규격에 맞게 펀칭하는 가공의 단계를 거친다.In the extrusion molding step, the dried mixture is supplied through an extruder hopper and injected into a melt extruder at a temperature of 160 ~ 200℃ and then pressed into a mold (die) by a screw installed inside the extruder melted into a gel-like liquid form. . When air is injected through the air inlet, the molten resin in the mandrel is expanded and continuously molded into a tube-shaped cylindrical film and moved upward. The molded film passes through a pair of nip rolls and is compressed according to the passing speed to control the thickness, and is transformed into a thin-thick sheet with the front and rear surfaces superimposed, and then moved by a plurality of guide rollers. During this process, it is further cooled to 20 ~ 26℃ by air, and is guided by a take-up roller to wrap and store the fabric. A fusion line is formed by fusion bonding at regular intervals while unwinding the rolled vinyl fabric. At the same time, the film is cut adjacent to the fusion line to be processed into a square bag with an open axis, and the opened part is cut to form a ring ring and a double-edged handle. , It goes through the steps of punching according to the standard of general cutting, etc.
