지퍼백용 중공 성형물 압출장치{Extruder for producing hollow product of zipper bag}Extruder for producing hollow product of zipper bag

본 발명은 지퍼백용 중공 성형물 압출장치에 관한 것으로, 더욱 상세하게는 물품의 수납공간을 형성하는 봉지부재의 상부에 봉지부재의 밀폐를 도모하는 지퍼부재가 일체로 성형된 지퍼백을 제조하는 중공 성형물을 압출 성형하는 지퍼백용 중공 성형물 압출장치에 관한 것이다.The present invention relates to a hollow molded article extrusion apparatus for a zipper bag, and more particularly to a hollow molded article for manufacturing a zipper bag integrally molded with a zipper member for enclosing the sealing member on the top of the sealing member forming the storage space of the article. The present invention relates to a blow molding extrusion device for a zipper bag for extrusion molding.

일반적으로 물품의 수납을 도모하는 지퍼백은, 물품의 수용공간을 형성하는 봉지부재의 상부에 지퍼부재가 형성된 형태로 구성되며, 상기 지퍼부재는 선형돌기와 선형홈이 대응되게 형성되어 이들의 압입을 통해 개방된 봉지부의 상부를 폐쇄하도록 구성된다.In general, the zipper bag to accommodate the article is configured in the form of a zipper member formed on the upper portion of the sealing member to form a receiving space of the article, the zipper member is formed to correspond to the linear projection and the linear groove through It is configured to close the top of the open encapsulation.

상기 지퍼백의 제조과정은, 일반적으로 봉지부재의 상부에 압출 성형을 통해 제작된 지퍼부재를 열 융착하거나, 압출을 통해 봉지부재와 지퍼부재를 일체로 성형하여 제조하는 방식이 주로 사용되고 있다.In the manufacturing process of the zipper bag, in general, the method of manufacturing by heat-sealing the zipper member produced by extrusion molding on the top of the sealing member, or integrally molding the sealing member and the zipper member through extrusion.

여기서 전자의 방식은, 봉지부재와 지퍼부재를 별도 제작하여야 하고, 또 이들을 열융착을 통해 이들을 접합하여야 하므로 제조 공정이 복잡해지는 단점을 가지나, 상기 봉지부재와 지퍼부재를 각기 다른 재질이나 색상으로 제작 가능하다는 이점을 갖는다.In the former method, the sealing member and the zipper member have to be manufactured separately, and they have to be bonded to each other through heat fusion, so that the manufacturing process is complicated, but the sealing member and the zipper member are manufactured in different materials or colors. It has the advantage of being possible.

따라서, 전자의 방식을 채택하여 제작된 지퍼백에 있어서는, 봉지부재는 물품의 수용에 적합한 물성을 갖고 또 지퍼부재는 안정된 기밀성에 요구되는 물성을 갖게 되므로, 결과적으로 향상된 품질 안정성이 높다.Therefore, in the zipper bag manufactured by adopting the former method, since the sealing member has physical properties suitable for accommodating the article and the zipper member has the physical properties required for stable airtightness, the improved quality stability is high as a result.
