Description
본 발명은 플라스틱필름류의 순간 열 접합을 위한 실링장치에 대한 것으로서, 더 상세하게는 열접합을 위한 히팅선재(니크롬선)를 직선형이 아닌 곡선형 또는 굴절형으로 하였을 때, 그 히팅선재가 열팽창에 의해 임의로 늘어 나더라도 들뜨는 부분이 없이 전 구간이 균일하게 열접착될 수 있도록 한데 특징이 있는 것이다.The present invention relates to a sealing device for instantaneous thermal bonding of plastic films, and more particularly, when the heating wire (nichrome wire) for thermal bonding is not curved but curved or refracted, the heating wire is subjected to thermal expansion. Even if it is arbitrarily stretched, it is characterized by the fact that the entire section can be uniformly heat-bonded without any lifting parts.
일반적으로 플라스틱필름류의 순간 열 접착을 위한 실링장치는 포장봉투의 개봉부분을 봉하기 위하여, 혹은 공기 저장부를 형성하기 위하여, 혹은 튜브류의 제품을 생산하기 위하여 널리 사용하고 있는 중이며, 그 실시예의 구성을 도 1 및 도 2에서 볼 수 있다.In general, sealing devices for instantaneous thermal bonding of plastic films are widely used to seal the openings of packaging bags, to form air reservoirs, or to produce tubular products. Can be seen in FIGS. 1 and 2.
도 1의 종래 실링장치는 히팅받침대(11)와, 그 상측에서 가압하기 위한 압착대(21)로 이루어 지는 바, 상기한 히팅받침대(11)의 상면에는 기본적으로 전원을 공급받아 발열하는 히팅선재(12)와, 열접착되는 플라스틱필름류가 히팅선재에 붙지 않도록 하기 위한 이형포(13)가 놓여 있고, 또 압착대(21)에는 완충부재(22)와, 역시 이형포(23)가 붙어 있다.The conventional sealing device of Figure 1 is composed of a heating bed 11, and the pressing table 21 for pressing from the upper side, the heating wire to heat the heat is basically supplied to the upper surface of the heating bed (11). (12) and a release cloth 13 for preventing the heat-bonded plastic film from sticking to the heating wire, and the crimping rod 21 is provided with a buffer member 22 and also a release cloth 23. .
이때, 상기한 이형포(23)는 테프론 등으로 이루어진 얇은 천의 형태이며, 상기 히팅선재(12)는 발열에 용이한 니크롬선재 등으로 이루어져 있다.At this time, the release cloth 23 is in the form of a thin cloth made of Teflon, etc., the heating wire 12 is made of nichrome wire and the like that is easy to heat.
그러나 상기와 같은 종래의 실링장치에서는 다음과 같은 미비점이 지적된다.However, the following defects are pointed out in the conventional sealing device as described above.
즉, 포장은 물론 튜브제품의 성능을 향상시키거나, 특수 목적으로 실링을 할 경우, 실링이 이루어지는 열접착부분을 직선형이 아닌 곡선의 형태나 굴곡진 형태로 할 필요가 있는데 종래의 실링장치로는 도 2에서 보는 바와 같이 직선형이고, 직선형이 아닌 형태로 실링할 수 없다는 것이 큰 단점이다.In other words, when improving the performance of tube products as well as packaging or sealing for special purposes, it is necessary to make the heat-sealed portion where the sealing is made in a curved or curved form rather than a straight form. As shown in FIG. 2, the drawback is that it is straight and cannot be sealed in a non-linear form.
그 이유는 실링을 하기 위한 히팅선재(12)를 직선형이 아닌 곡선형이나 굴곡진 형태로 고정하여 실링작업을 할 경우, 열팽창으로 늘어날 수가 없어 일부분이 뒤틀리거나(Distortion), 팽창된 힘에 의해 들뜬 선재의 단면이 변하며, 반복사용으로 인한 과열로 용접부분이 끊어져 단선되는 결과를 가져오기 때문이다.The reason for this is that when sealing the heating wire 12 for sealing in a curved or curved form rather than a straight shape, the sealing wire cannot be stretched due to thermal expansion, so that a portion is distorted, or is excited by the inflated force. This is because the cross section of the wire is changed and the welded part is broken due to overheating due to repeated use.
들뜨는 현상은 히팅선재(12)가 갖는 열팽창 계수의 값만큼 사방으로 동일하게 열팽창을 하기 때문에 곡선을 이루는 부분 또는 각을 가지고 굴곡진 부분에서 발생하는 것이며, 단선되는 현상은 히팅선재가 받침부재에 고정되어 있는 관계로 열팽창시 히팅선재가 자유로이 팽창할 수 없어 히팅선재의 가장 취약한 부분이 들뜨거나 뒤틀려 선재의 단면이 변화되어 이곳에 집중열이 발생, 반복사용으로 인한 과열로 발생하는것이다.The lifting phenomenon occurs in the curved part or the curved part because the thermal expansion is equally performed in all directions by the value of the thermal expansion coefficient of the heating wire 12, and the disconnection phenomenon is the heating wire is fixed to the supporting member. Because the heating wire cannot expand freely during thermal expansion, the most vulnerable part of the heating wire is lifted up or distorted to change the cross section of the wire, resulting in concentrated heat and overheating due to repeated use.
결국, 이와 같은 들뜸현상으로 인하여 필름접착부분의 흠집이 생기며 또한 들뜸에 따른 뒤틀림으로 단선되는 현상을 극복하지 못하였기 때문에 곡선형 또는 굴곡진 형태의 히팅선재로는 열접착작업을 할 수 없었다.As a result, the above phenomenon of the lifting caused scratches on the film adhesive part and the breakage caused by the distortion caused by the lifting could not be overcome, and thus the heat-bonding work was not possible with the curved or curved heating wire.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하여 안출한 것으로, 발명의 주된 목적은 굴곡진 모양 또는 곡선형의 히팅선재를 만들어 사용하더라도 들뜸현상이나 단선현상이 발생하지 않도록 하고자 하는데 있으며, 더 나가서 곡선형과 굴곡진형은 물론 그 어떤형태의 모양으로도 순간열접착이 가능하도록 하여 다양한 제품의 생산성을 크게 높일 수 있도록 하고자 하는데 있는 것이다.Therefore, the present invention has been made to solve the conventional problems as described above, the main object of the invention is to prevent the lifting or disconnection phenomenon occurs even if used to create a curved or curved heating wire, It is intended to greatly increase the productivity of various products by enabling instant thermal bonding in curved and curved shapes as well as in any shape.
상기 목적을 달성하기 위한 본 발명의 특징적인 구성으로는 전원이 연결되었을 때 열을 발하는 히팅선재와, 상기 히팅선재를 받쳐주기 위한 받침부재와, 상기 받침부재 및 히팅선재를 덮는 이형포로 이루어진 히팅 받침대와, 상기 받침구조의 상측에 직상방에 마련하되, 이형포를 포함하는 압착대로 이루어진 실링장치에 있어서, 상기한 히팅 받침대는 상기 히팅선재와 받침부재의 사이에 상면과 저면에 단열포를 개입시킨 자석판재를 받쳐 팽창된 히팅선재가 늘어나도 들뜨지 않도록 하는데 있다.A characteristic configuration of the present invention for achieving the above object is a heating pedestal consisting of a heating wire that generates heat when the power is connected, a support member for supporting the heating wire, and a release cloth covering the support member and the heating wire And, provided on the upper side of the supporting structure directly above, in the sealing device made of a pressing table including a release cloth, the heating pedestal through the insulating cloth interposed between the heating wire and the supporting member on the upper surface and the bottom surface It supports the magnetic sheet to prevent the heating wire expanded from expanding.

도 4는 본 발명의 실링장치 구성을 보인 분해 사시도이고, 도 5는 그 구성을 상세히 보이기 위한 조립상태의 단면도이다.Figure 4 is an exploded perspective view showing the configuration of the sealing apparatus of the present invention, Figure 5 is a cross-sectional view of the assembled state for showing the configuration in detail.
도면에서 보듯이 본 발명도 히팅 받침대(30)와, 압착대(40)로 이루어 진다.As shown in the drawing, the present invention also includes a heating pedestal 30 and a crimping table 40.
압착대(40)는 압착부재(41)와, 그 압착부재(41)의 밑에 쿳션부재(42)와, 철판부재(43)와, 쿳션부재(42)를 샌드위치식으로 조립하였다.The crimping | compression-bonding stand 40 assembled the compression member 41, the cushion member 42, the iron plate member 43, and the cushion member 42 under the crimping member 41 by the sandwich type.
히팅 받침대(30)는 전원이 연결되었을 때 열을 발하는 히팅선재(50)와, 상기히팅선재를 받쳐주기 위한 받침부재(31)와, 상기 받침부재 및 히팅선재를 덮는 이형포(32)로 구성하되, 상기의 히팅선재(50)와 받침부재(31)의 사이에 상면과 저면에 단열포(33)를 개입시킨 자석판재(34)를 받쳐 조립하는 것이다.The heating pedestal 30 is composed of a heating wire 50 that generates heat when the power is connected, a support member 31 for supporting the heating wire, and a release cloth 32 covering the support member and the heating wire. However, between the heating wire 50 and the support member 31 is to be assembled to support the magnetic plate member 34 through the heat insulating cloth 33 on the upper and lower surfaces.
이때, 상기한 자석판재(34)는 고무자석판으로 할 수도 있고, 전원이 공급됨에 따라 자성을 발휘하는 전자석 또는 영구자석으로 할 수도 있다.At this time, the magnetic plate 34 may be a rubber magnetic plate, or may be an electromagnet or permanent magnet that exerts magnetic properties as power is supplied.
도면 중 미설명 부호 60은 압착 작업이 효과적으로이루어질 수 있도록 하기 위한 스프링장치이다. B는 플라스틱필름이다.Reference numeral 60 in the drawings is a spring device for effectively performing the crimping operation. B is a plastic film.
이와 같이 조립된 본 발명의 실링장치는 도 5에서 보는 바와 같이 히팅 받침대(30)의 위에 플라스틱필름(B)을 올려 놓고 압착대(40)를 하강시켜 실링작업을 실시하게 되면 히팅선재(50)에 공급되는 전원에 따라 히팅선재(50)가 순간적으로 발열하고, 그 발열에 따라 2겹 이상의 플라스틱필름(B)이 열접착되는 것이다.The sealing device of the present invention assembled as described above is put on the plastic film (B) on the heating pedestal 30 as shown in Figure 5 when the sealing operation is carried out by lowering the pressing table 40 heating wire 50 In accordance with the power supplied to the heating wire 50 is instantaneously generated, two or more layers of plastic film (B) is heat-bonded according to the heat generated.
본 발명에서는 상기와 같이 가열되는 굴곡진 모양의 히팅선재(50)가 반복적으로 열을 받음에 따라 팽창되어도 그 밑에 자석판재(34)가 받쳐져 있기 때문에 들떠 오르지 않고, 그대로 받침부재(31)의 위에 밀착되어 있으며 자유롭게 자석판재 평면상에서 팽창수축을 반복하게 된다.In the present invention, even if the curved heating wire 50 is heated as described above, even if it expands as it is repeatedly heated, the magnetic plate 34 is supported thereon, so that it does not rise, and the support member 31 remains as it is. It is in close contact with it and freely repeats expansion and contraction on the magnetic plate plane.
상기의 단열포(33)는 자석판재(34)가 열을 받으면 자력이 손실될 수 있으므로 자력의 상실을 예방하기 위한 중요한 요소이다.The heat insulating cloth 33 is an important element for preventing the loss of magnetic force because the magnetic force may be lost when the magnetic plate 34 receives heat.
또, 자석판재(34)를 고무자석판으로 하면 어느정도 완충작용을 하기 때문에 열접착 작업이 더 잘될 수도 있으며, 때에 따라서 상기 자석판재(34)를 전자석으로할 수도 있는데 전자석으로 할 경우 열압착하는 순간, 즉, 전원이 공급되는 순간에만 자성을 발휘하므로 기타 다른 작업에 영향을 미치지 않게 할 수도 있다.In addition, when the magnetic plate 34 is made of a rubber magnetic plate to some extent buffering action may be better thermal bonding work, and sometimes the magnetic plate 34 may be an electromagnet, when the electromagnet when the thermocompression bonding, That is, it can be magnetized only when power is applied, so that it does not affect other tasks.
위에서 상세히 설명한 바와 같은 본 발명은 플라스틱필름류를 열압착하는데 있어서, 히팅선재의 모양이 직선형이 아니라 곡선형 또는 굴곡형으로 되어 있어 열팽창된다 하더라도 밑에 자석판재가 받치고 있기 때문에 들뜨는 현상이 예방되며, 들뜨는 현상이 예방되므로 해서 히팅선재가 단락되는 일도 없다.In the present invention as described in detail above, in the thermocompression bonding of plastic films, even though the shape of the heating wire is not linear but curved or curved, the magnet plate is supported by the bottom even if thermally expanded, thereby preventing the lifting phenomenon. This prevents the heating wire from shorting out.
따라서 본 발명의 실링장치에 의하면 실링하는 부분을 곡선형 또는 굴곡진 모양으로 폭넓게 설계할 수 있으며, 이와 같이 실링되는 제품은 기능을 향상시킬 수 있고, 또 생산성을 크게 향상시킬 수 있으며, 기존 카트리지 히터를 사용한 열접착 블록보다 에너지 효율 및 접착성능을 향상시킬 수 있는 여러 가지 장점을 가지는 것이다.Therefore, according to the sealing device of the present invention, the sealing portion can be designed in a curved or curved shape widely, and the product thus sealed can improve the function and greatly improve the productivity, and the existing cartridge heater. Has a number of advantages that can improve the energy efficiency and adhesion performance than the thermal bonding block using.
