다이아몬드형 발포 폴리에틸렌 패드 제작방법{Manufacturing method for pad of foaming poly-ethylen}Manufacturing method for diamond foam polyethylene pad {Manufacturing method for pad of foaming poly-ethylen}

본 발명은 다이아몬드형 발포 폴리에틸렌 패드 제작방법에 관한 것으로써, 더욱 상세히는 발포 폴리에틸렌 시이트에 프레스 성형기로 'I'자형 절개부를 다수개 형성한 후 75℃~85℃로 1~3초 가열하면서 좌/우로 잡아당긴 후 급랭시켜 시이트가 벌어져 통공이 형성된 그대로 형태를 유지한 다음 제품의 용도에 따라 커팅하여 통공이 형성되어 통기성을 향상시키는 발포 폴리에틸렌 패드 제작방법을 제공하기 위한 것이다.The present invention relates to a diamond-like foamed polyethylene pad manufacturing method, more specifically, after forming a plurality of 'I' shaped incision in the foamed polyethylene sheet by a press molding machine while heating for 1 to 3 seconds at 75 ℃ ~ 85 ℃ It is to provide a foamed polyethylene pad manufacturing method to improve the air permeability by pulling to the right and then quenched to maintain the form as the sheet is formed to form a through hole and then cut according to the use of the product to form a through hole.

일반적으로 배낭과 같은 가방의 형태를 유지하기 위해서 사용되는 내부 심재나, 노트북 컴퓨터 가방의 충격흡수재로 가볍고 완충력을 가진 발포 폴리에틸렌이 주로 사용되었다.In general, a lightweight and cushioning foam polyethylene is mainly used as an inner core material used to maintain the shape of a bag such as a backpack or a shock absorber of a laptop computer bag.

즉, 도 1 에서 도시되는 바와 같이 배낭의 등판(10) 등에 가방의 형태를 유지하기 위해 발포 폴리에틸렌 패드(20)가 내부 심재로 겉감(11) 사이에 삽입되어 봉재되는 것이다.That is, as shown in FIG. 1, in order to maintain the shape of the bag on the back plate 10 of the backpack, the foamed polyethylene pad 20 is inserted between the outer core 11 as an inner core and is sealed.

그런데 상기 발포 폴리에틸렌 패드(20)는 시이트(sheet)를 모양 그대로 커팅만 한채 사용되므로 배낭 등판에 사용될 경우 통풍이 전혀 이루어 지지 않아 사용시 땀이 배고 중량이 많이 나가는 문제점이 있었다.By the way, since the foam polyethylene pad 20 is used while cutting a sheet as it is, the ventilation is not performed at all when used in a backpack backing, and thus there is a problem in that the sweat becomes hungry and a lot of weight is used.

따라서 본 발명의 목적은 배낭 등판 등에 사용될 때에도 통기성이 뛰어나고 가벼우며 완충력이 향상된 다이아몬드형 발포 폴리에틸렌 패드 제작방법을 제공하는데 있다.Accordingly, an object of the present invention is to provide a diamond-like foamed polyethylene pad manufacturing method excellent in breathability, light weight and improved buffering capacity even when used in backpack back.

이와 같은 본 발명의 목적은 발포 폴리에틸렌 시이트(sheet)에 프레스 성형기로 'I' 형 절개부를 소정 간격으로 다수개 형성하는 과정(S10); 상기 과정을 거친 발포 폴리에틸렌 시이트를 75℃ ~ 85℃에서 1~3초 가열하면서 좌/우 양쪽에서 인력을 가한 후 급랭시켜 시이트가 벌어진 상태에서 통공을 형성하는 과정(S20); 상기 과정을 거친 발포 폴리에틸렌 시이트를 알맞은 크기로 커팅하는 과정(S30);을 순차적으로 수행하므로써 달성되는 것이다.Such an object of the present invention is to form a plurality of 'I' type incision at a predetermined interval by a press molding machine in a foamed polyethylene sheet (S10) (S10); Forming a through hole in a state where the sheet is opened by quenching the foamed polyethylene sheet having undergone the above process at 75 ° C. to 85 ° C. for 1 to 3 seconds while applying attractive force at both left and right sides (S20); It is achieved by sequentially performing the step (S30) of cutting the foamed polyethylene sheet through the above process to a suitable size.

이러한 본 발명은 간단한 공정으로 발포 폴리에틸렌 시이트에 다이아몬드형 통공을 형성하므로써 통풍 효과를 가져오고 기존의 발포 폴리에틸렌 패드보다 완충력이 향상되며 중량이 감소되고 재료를 절감할 수 있으므로 상기 목적을 효과적으로 달성할 수 가 있는 것이다.The present invention can achieve the above object effectively by forming a diamond-shaped through-hole in the foamed polyethylene sheet in a simple process, the ventilation effect is improved, the buffering capacity is improved, the weight is reduced and the material can be saved compared to the conventional foamed polyethylene pad It is.

이하 본 발명의 목적을 효과적으로 달성할 수 있는 바람직한 실시 예로서 그 기술구성 및 작용 효과를 첨부한 별첨의 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, which are attached to the technical configuration and the effect of the present invention.

즉, 도 2 는 본 발명에 의한 다이아몬드형 발포 폴리에틸렌 패드 제작방법을 나타낸 개략도로서 도면에서 도시하는 바와 같이 본 발명은 발포 폴리에틸렌 시이트(sheet;100)에 프레스 성형기로 'I' 형 절개부(110)를 소정 간격으로 다수개 형성하는 과정(S10); 상기 과정을 거친 발포 폴리에틸렌 시이트(100)를 75℃ ~ 85℃에서 1~3초 가열하면서 좌/우 양쪽에서 인력을 가한 후 급랭시켜 시이트(100)가 벌어진 상태에서 통공(120)을 형성하는 과정(S20); 상기 과정을 거친 발포 폴리에틸렌 시이트를 알맞은 크기로 커팅하는 과정(S30)을 순차적으로 수행하는 것이다.That is, Figure 2 is a schematic diagram showing a diamond-like foamed polyethylene pad manufacturing method according to the present invention, as shown in the drawing the present invention 'I' type incision 110 to the foamed polyethylene sheet (sheet; 100) by a press molding machine Forming a plurality of at predetermined intervals (S10); The process of forming the through-holes 120 in the state in which the sheet 100 is opened by quenching the foamed polyethylene sheet 100 subjected to the above process by applying attractive force at both left and right sides at 75 ° C. to 85 ° C. for 1 to 3 seconds. (S20); It is to sequentially perform the step (S30) of cutting the foamed polyethylene sheet through a suitable size.

상기 발포 폴리에틸렌 시이트(100)는 폴리에틸렌을 포밍(foaming) 압출하여 시이트 (sheet) 형태로 형성하여 구성한다.The expanded polyethylene sheet 100 is formed by foaming polyethylene to form a sheet (sheet) form.

S10 과정은 이러한 발포 폴리에틸렌 시이트(100)를 다수개의 'I'자형 칼날이 소정간격으로 형성된 프레스 성형기로 프레스 성형하므로써 상기 시이트(100)에 소정간격으로 다수개의 'I'자형 절개부(110)를 형성하는 단계이다.In step S10, the foamed polyethylene sheet 100 is press-molded into a press molding machine in which a plurality of 'I' shaped blades are formed at predetermined intervals, thereby forming a plurality of 'I' shaped cutouts 110 at the predetermined intervals on the sheet 100. Forming.

그리고, S20 과정은 상기 S10 과정에서 절개부(110)가 형성된 시이트(100)를 75℃~85℃ 정도로 1~3초 가열해 주면서 좌/우로 잡아당겨 절개부(110)를 벌려 통공(120)을 형성한 후 급랭시켜 벌어진 상태를 그대로 유지하는 단계이다.And, in step S20, the sheet 100 formed with the cutout 110 in the step S10 is heated at about 75 ° C. to 85 ° C. for 1 to 3 seconds while pulling to the left / right to open the cutout part 110 through the opening 120. After forming the quenching step is to maintain the state opened.

상기 'I'자형 절개부(110)는 상/하단에 가로방향 슬릿(111)이 형성되므로 S20 과정에서 절개부(110)를 벌려 통공을 형성하기 위하여 좌/우로 인력이 작용하는 경우에도 세로 방향으로 찢어지는 현상을 방지하게 된다.The 'I' shaped cutout 110 has a horizontal slit 111 formed at the top / bottom, so in the vertical direction even when an attractive force acts to the left / right to open the cutout 110 to form a through hole in the S20 process. This will prevent tearing.

또한, S20 과정에서 시이트(100)에 통공(120)이 형성되어 제품의 완충력은 향상되고 통공(120)이 형성된 만큼 중량이 감소하고, 같은 부피를 생산할 때 종래에 비해 발포 폴리에틸렌 재료 또한 약 50% 절감할 수 있게 된다.In addition, the through hole 120 is formed in the sheet 100 in S20 to improve the buffering force of the product, the weight decreases as the through hole 120 is formed, and when the same volume is produced, the polyethylene foam material is also about 50% compared with the conventional one. You can save.

그리고, S30 과정은 상기 S20 과정에서 통공(120)이 형성된 시이트(100)를 제품의 용도에 따라 알맞은 크기로 커팅하여 통공이 형성된 발포 폴리에틸렌 패드를 제작하는 단계이다.And, the step S30 is a step of producing a foamed polyethylene pad with a through-hole by cutting the sheet 100, the through-hole 120 is formed in a suitable size according to the use of the product in the S20 process.

이상에서 상술한 바와 같이 본 발명은 상기와 같이 발포 폴리에틸렌 시트를 절개하여 고온에서 잡아당겨 통공을 형성한 다음 급랭하여 통공을 형성하므로써 배낭 등판에 사용시 통풍 효과를 거둘 수 있게 되고, 통공이 형성되는 만큼 중량이 감소하고 같은 부피 생산시에도 종래에 비해 50%정도 재료를 절감할 수 있게 되며 완충력이 커 노트북 컴퓨터 가방 내부의 충격흡수재로도 사용할 수 있는 유용한 발명이다As described above, the present invention can cut through the polyethylene foam sheet as described above to form a through-hole pulled at a high temperature and then quenched to form a through-hole to achieve a ventilation effect when used in the backpack back, as the through-hole is formed It is a useful invention that can be used as a shock absorber inside a laptop computer bag because it reduces weight and can save 50% of materials compared to the conventional one even when producing the same volume.
