Description
본 고안은 합성수지필름의 결합부 성형다이에 관한 것으로, 보다 상세하게는 암, 수결합수단의 이중결합으로 비닐봉지의 입구를 개폐시킴으로 긴밀히 밀폐 또는 해제시킬 수 있는 비닐봉지를 성형하는 합성수지필름의 결합부 성형다이에 관한 것이다.The present invention relates to a coupling die forming die of a synthetic resin film, and more specifically, a combination of a synthetic resin film forming a plastic bag that can be tightly sealed or released by opening and closing a plastic bag by double bonding of a female and a water coupling means. It relates to a secondary molding die.
종래 합성수지필름의 결합부 성형다이는 압축 이송스크류의 회전에 의해 합성수지필름을 성형다이로 통과시키면 성형다이에 형성된 성형홈에 의해 걸림돌기와 삽입공 그리고 미끄럼돌기가 형성되도록 한 것이다.Conventional molded part molding die of the synthetic resin film is to pass the synthetic resin film to the molding die by the rotation of the compression feed screw is to form a locking projection, the insertion hole and the sliding protrusion by the molding groove formed in the molding die.
이와같은 종래의 기술은 상기 걸림돌기를 삽입공에 삽입함에 의해 비닐봉지의 입구를 상호결합하고, 비닐봉지의 입구에 형성된 미끄럼방지돌기에 의해 미끄럼없이 밀폐된 비닐봉지의 입구를 해제시킬 수 있도록 한 것이다.Such a conventional technique is to allow the inlet of the plastic bag to be mutually coupled by inserting the locking protrusion into the insertion hole, and to release the inlet of the slippery sealed plastic bag by the anti-slip protrusion formed at the inlet of the plastic bag. .
그러나 위와 같은 종래의 기술은 걸림돌기가 삽입공에 끼워진다 해도 걸림돌기와 삽입공 하나만으로 긴밀히 비닐봉지내의 밀폐력을 확보할 수 없어(즉, 걸림돌기와 삽입공의 사이에 미세한 공간부가 형성됨)만일 비닐봉지내에 액상의 내용물이 저장되면 걸림돌기와 삽입공의 미세한 틈으로 액상의 내용물이 외부로 누수되는 문제점이 내포되었던 것이다.However, in the conventional technique as described above, even if the locking projection is inserted into the insertion hole, the sealing force in the plastic bag cannot be secured tightly with only the locking projection and the insertion hole (that is, a minute space is formed between the locking projection and the insertion hole). If the contents of the liquid is stored there is a problem that the contents of the liquid is leaked to the outside by a minute gap between the locking projection and the insertion hole.
또한 상기 종래의 기술은 밀폐된 비닐봉지의 입구를 해제시킬 때 미끄럼돌기가 형성되어 사용자는 미끄럼없이 비닐봉지의 입구를 해제시킬 수 있도록 한 것이나, 상기 미끄럼돌기의 형상이 가늘게 형성됨으로 인해 쉽게 마모되고 그로 인해 비닐봉지의 입구가 쉽게 구겨져 외관상 보기 좋지 못하다는 문제점이 있었다.In addition, the prior art is that the sliding protrusion is formed when the inlet of the sealed plastic bag is released so that the user can release the inlet of the plastic bag without slipping, but the shape of the sliding protrusion is easily worn due to the thinner shape As a result, the entrance of the plastic bag is easily crumpled, there is a problem that the appearance is not good.
본 고안은 상기와 같은 종래 기술의 제반 문제점을 해소하기 위하여 안출한 것으로서, 압출코어에 형성된 걸림돌기성형홈, 결합편성형홈, 걸림편성형홈에 의해 비닐봉지의 적소에 암, 수결합수단을 형성하여 1차적으로 걸림돌기와 돌기홈이 형성된 걸림편에 의해 비닐봉지내부의 기밀을 유지시키는 동시에 2차적으로 결합편이 걸림편의 외주면에 끼워져 비닐봉지내부를 더욱 긴밀히 밀폐시킬 수 있도록 함을 제1목적으로 하는 것이고, 제2목적은 비닐목적은 비닐봉지에 암, 수결합수단을 하나이상 형성하여 더욱 더 비닐봉지내부의 밀폐력을 확보하도록 하며, 제3목적은 미끄럼을 방지하기 위해 돌기가 형성된 미끄럼방지수단에 보강부를 형성하여 장시간 사용할 때에도 돌기가 쉽게 마모되지 않도록 하는 동시에 비닐봉지 입구의 형상이 쉽게 구겨지지 않아 외관상 보기좋게 하도록 한 합성수지필름을 만들어내는 합성수지필름의 결합부 성형다이를 제공하는데 그 목적이 있다.The present invention has been made in order to solve all the problems of the prior art as described above, and the female, male coupling means in place of the plastic bag by the locking projection forming groove, the coupling knitting groove, the locking knitting groove formed in the extrusion core. The first purpose is to maintain the airtightness inside the plastic bag by means of the locking pieces formed by the first locking projections and the projection grooves, and secondly, the coupling pieces can be fitted to the outer circumferential surface of the locking pieces to more closely seal the inside of the plastic bags. The second purpose of the vinyl purpose is to form one or more female and male coupling means in the plastic bag to secure the sealing force in the plastic bag even more, and the third purpose is the anti-slip means having protrusions to prevent slipping. The reinforcement part is formed on the inside of the plastic bag so that the protrusion does not easily wear out even when used for a long time. Not to provide the engaging portions of the synthetic resin film molding die to produce a synthetic resin film so as to improve appearance view it is an object.
이러한 목적들을 달성하기 위하여 본 고안은 심체의 상단에 고정설치되며, 외주면의 내측 적소에 제1, 2걸림편성형홈, 제1, 2걸림돌기성형홈, 제1, 2결합편성형홈이 구비된 압출코어, 압출코어와 하우징의 사이에 공간부가 이루어지게 설치되며, 내측면 적소에 제1, 2돌기성형홈과 제1, 2보강부성형홈이 구비된 압출다이, 하우징의 적소에 하나 이상 설치되며, 공간부로 관통되어 정, 역회전시킴에 따라 압출다이의 위치를 조절하는 간격조절부재, 이하에서 이러한 목적달성을 위한 본 고안의 바람직한 실시예를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.In order to achieve these objectives, the present invention is fixedly installed on the upper end of the core, and the first and second locking grooves, the first and second locking grooves, and the first and second coupling grooves are provided in the inner place of the outer peripheral surface.

상기와 같이 형성된 본원고안의 합성수지필름제품(40)은 도4, 5에 도시된 바와 같이 상하단에 형성된 제1, 2걸림돌기(52)(52a)는 제1, 2걸림편(50)(50a)에 형성된 제1, 2돌기홈(51)(51a)에 끼워져 비닐봉지내부의 밀폐력을 긴밀히 확보하는 것이다.In the synthetic resin film product 40 of the present application formed as described above, the first and second locking projections 52 and 52a formed at the upper and lower ends thereof are first and second locking pieces 50 and 50a as shown in FIGS. 4 and 5. It is inserted into the first and second projection grooves 51 and 51a formed in the c) to secure a tight sealing force inside the plastic bag.
또한 이때 상기 제1, 2걸림편(50)(50a)에 끼워져 설치되는 동시에 제1, 2걸림편(54)(54a)은 제1, 2걸림편(50)(50a)의 외주면에 끼워져 더욱 더 비닐봉지 내부의 밀폐력을 확보하는 것이다.In this case, the first and second locking pieces 50 and 50a may be inserted into and installed at the same time, and the first and second locking pieces 54 and 54a may be fitted to the outer circumferential surfaces of the first and second locking pieces 50 and 50a. It is to ensure the sealing force inside the plastic bag.
즉, 보다 상세히 설명하면 상기 제1, 2결합편(54)(54a)이 제1, 2걸림편(50)의 외주면에 끼워지므로, 수결합수단(41)과 암결합수단(42)이 쉽게 이탈되는 것을 방지하는 것이고, 2중의 밀폐력을 확보하여 비닐봉지 내부의 밀봉효과를 향상시킬 수 있도록 한 것이다.In other words, since the first and second coupling pieces 54 and 54a are fitted to the outer circumferential surfaces of the first and second locking pieces 50, the male coupling means 41 and the female coupling means 42 are easily described. It is to prevent the departure, and to ensure a double sealing force to improve the sealing effect inside the plastic bag.
그리고 본원고안은 합성수지필름제품(40)의 입구 외주면에 제1, 2돌기(61)(61a)를 형성하여 비닐봉지 입구 해제시 상기 제1, 2돌기(61)(61a)에 의해 미끄럼을 방지하는 것이고, 이 제1, 2돌기(61)(61a)는 합성수지필름제품(40)의 양면에 형성하여 미끄럼 없이 비닐봉지의 입구를 해제시킬 수 있도록 한 것이다.In addition, the present application forms the first and second protrusions 61 and 61a on the outer circumferential surface of the inlet of the synthetic resin film product 40 to prevent slippage by the first and second protrusions 61 and 61a when the plastic bag inlet is released. The first and second protrusions 61 and 61a are formed on both sides of the synthetic resin film product 40 so that the entrance of the plastic bag can be released without slipping.
또한 미끄럼방지수단(60)의 적소에는 제1, 2보강부(62)(62a)를 형성하여 제1, 2돌기(61)(61a)가 쉽게 마모됨을 방지하는 동시에 비닐봉지 입구의 형상이 구겨짐이 없도록 하여 외관상 보기좋도록 한 것이다.In addition, the first and second reinforcing parts 62 and 62a are formed in place of the non-slip means 60 to prevent the first and second protrusions 61 and 61a from being easily worn, and at the same time, the shape of the plastic bag inlet is wrinkled. This is to make it look good.
이상에서와 같은 본 고안은 압출코어에 형성된 걸림돌기성형홈, 결합편성형홈, 걸림편성형홈에 의해 비닐봉지의 적소에 암, 수결합수단을 형성하여 1차적으로 걸림돌기와 돌기홈이 형성된 걸림편에 의해 비닐봉지 내부에 기밀을 긴밀히 유지시키는 동시에 2차적으로 결합편이 걸림편의 외주면에 끼워져 비닐봉지내부를 더욱 긴밀히 밀폐시킬 수 있도록 하는 것이고, 비닐봉지에 암, 수결합수단을 하나 이상 형성하여 더욱 더 비닐봉지내부의 밀폐력을 확보하도록 하며, 미끄럼을 방지하기 위해 돌기가 형성된 미끄럼방지수단에 보강부를 형성하여 장시간 사용할 때에도 돌기가 쉽게 마모되지 않도록 하는 동시에 비닐 봉지 입구의 형상이 쉽게 구겨지지 않아 외관상 보기좋게 하는 제품을 만들어낼 수 있는 유용한 고안인 것이다.The present invention as described above is formed by the locking projection forming groove, the coupling knitting groove, the locking knitting groove formed in the extrusion bag, the female, male coupling means formed in place of the plastic bag, the first locking hook and the projection groove is formed By keeping the airtight inside the plastic bag tightly by the piece, and the secondary piece is inserted into the outer circumferential surface of the fastening piece so that the inner part of the plastic bag can be sealed more tightly. In order to secure the sealing force inside the plastic bag, and to prevent slipping, a reinforcing part is formed on the non-slip means formed with protrusions so that the protrusions are not easily worn even when used for a long time and the shape of the plastic bag inlet is not easily wrinkled. It is a useful design that can make a good product.
