Description

단프라시트의 격자 융착시스템{sealing system for lattice of plastic corrugated cardboard}Lattice fusion system of short plastic sheet {sealing system for lattice of plastic corrugated cardboard}

본 발명은 단프라시트의 격자 융착시스템에 관한 것으로, 보다 상세하게는 절단칼날이 부착된 1차융착롤러로 상기 단프라시트의 격자벽을 소정 깊이로 절단하고, 성형하고자하는 형상의 성형부가 구비된 2차융착롤러에 상기 격자벽이 절단된 단프라시트를 통과시켜 단프라시트에 형성된 격자를 융착시켜 밀봉하게 되며, 곡선부형상을 음각한 곡선성형부를 구비하여 열과 압력을 가해 곡선부를 밀봉하게되는 시스템에 관한 것이다.The present invention relates to a lattice fusion system of a short plastic sheet, and more particularly, to a first fusion roller with a cutting blade, to cut the lattice wall of the short plastic sheet to a predetermined depth, and having a molded part having a shape to be molded. The lattice wall is cut through the short plastic sheet cut through the lattice fusion roller, and the lattice formed on the short plastic sheet is fused and sealed, and the curved portion is engraved with the curved portion to seal the curved portion by applying heat and pressure. It is about a system.

단프라시트(Danpla Sheet)는 도1에 도시된 바와 같이 폴리프로필렌 공중합(PP Copolymer)수지를 고도의 압축 성형법에 의하여 일체 중공 구조 및 골판상 구조식 플라스틱 카튼보드로서 강하고,가볍고,내수,내유,내약품성이 우수하며, 탄력유지 및 단열,방음,다양한 색상 등, 완충성도 우수하여 각종 내외포장, 운반용상자, 산업용 자재, 포장용기, 회수용, 농수산물 운반용, 대전방지용, 통신기기, 컴퓨터, 자동차부품, 선물포장, 전자제품 포장 등에 다양하게 사용되고 있다.Danpla Sheet, as shown in Fig. 1, is a hollow hollow and corrugated plastic carton board made of polypropylene copolymer (PP Copolymer) by high compression molding method, which is strong, light, waterproof, oilproof, and oilproof. Excellent chemical properties, excellent elasticity, insulation, sound insulation, various colors, etc., and excellent buffering properties, various internal and external packaging, transport boxes, industrial materials, packaging containers, recovery, agricultural and marine products transport, antistatic, communication equipment, computer, automobile parts, It is widely used for gift packaging and electronics packaging.

상기 단프라시트는 폴리프로필렌으로 제작되므로 일반적으로 포장에 사용되는 종이 골판지에 비해 내구성이 뛰어나므로 여러번의 재사용이 가능하다는 장점이 있다.Since the short plastic sheet is made of polypropylene, it is generally superior in durability compared to paper corrugated cardboard used for packaging, and thus has the advantage of being reused many times.

그러나 상기 단프라시트는 격자가 외부로 노출되어 있어 세척을 하게 되면, 수분과 이물질이 상기 격자내부로 들어가 내부가 오염되는 문제가 있다.However, the short plastic sheet is exposed to the outside of the lattice when washed, there is a problem that the water and foreign substances enter the inside of the lattice to contaminate the inside.
