본 고안은 이송로울러에 의하여 이송공급되는 튜우브 상 항성수시 필름읕 일정간격을 두고 평행하게 설치되는 2열의 용착날과 이들 사이에 분리될수 있게 설치되는 절단칼로써 용착, 절단하여 합성수지 포대를 연속적으로 제조하는 제동 제대기의 절단칼 장치에 관한 것으로, 특히 용착날과 일체로 조립되는 절단칼이 가열됨에 따른 왜곡 변형요인을 배제함과 아울러 절단칼의 일부가 마모 또는 손상될 경우 그 해당 부위만의 부분 교체가 가능하게 한 합성수지 포대 제조기의 절단칼 장치에 관한 것이다,The present invention is to continuously feed the synthetic resin bag by welding and cutting with two rows of welding blades installed parallel to each other at a certain interval between the tubulars fed by the feed rollers at regular intervals, and cutting knives installed to be separated therebetween. The present invention relates to a cutting knife device of a braking device for manufacturing a braking device, in which a distortion deformation factor caused by heating of a cutting knife integrally assembled with a welding blade is excluded, and only a portion of the cutting knife is worn or damaged. The present invention relates to a cutting knife device of a synthetic bag manufacturing machine, which enables partial replacement.

일반적으로 사용되고 있는 종래의 합성수지 포대 제조기에 있어서는 통상 합성수지 필름의 용착작업과 절단작업이 각기 분리 시행되고 있어, 용착장치에 의하여 용착된 합성수지 필름이 절단장치까지 이송되는 과정에서 그 용착부분이 늘어나게 됨에 따라 선정된 절단위치와 절단칼에 의한 절단위치가 일치되지 않게되는 결함이 발생되므로 절단되는 포대의 규격이 정확히 맞지않게 되는 난점이 있으며, 또한 절단칼의 하강 작동이 수평이동되는 튜우브의 진행방향에 대하여 직교되는 수직방향으로 작용되어 절단칼이 쉽게 마모 손상되는 단점이 있었다.In the conventional synthetic resin bag manufacturing machine generally used, the welding and cutting operations of the synthetic resin film are separately performed, and as the welded portion increases in the process of transferring the welded synthetic resin film to the cutting device, There is a problem that the size of the bag to be cut is not exactly matched because a defect occurs that the selected cutting position and the cutting position by the cutting knife do not coincide, and the lowering operation of the cutting knife is in the moving direction of the tubing that is moved horizontally. There was a disadvantage that the cutting knife is easily worn and damaged because it is acted in a vertical direction perpendicular to it.

한편, 이와같은 종래의 결함 및 단점을 해소하기 휘하여 용착날콰 절단칼을 일체화하되 그 용착날과 절단칼이 각기 분리 구성되게 하여 이송벨트에 의하여 이송 공급되는 합성수지 튜우브의 용착과 절단이 거의 동시에 이루어지게 하고, 절단칼의 마모시에는 그 절단칼만을 분리 교체할수 있게한 합성수지 포대 제조기의 용착 절단장치가 알려져 있다.On the other hand, in order to eliminate such defects and drawbacks of the prior art, the welding blade and cutting knife are integrated, and the welding blade and the cutting knife are separately configured so that the welding and cutting of the synthetic tubing fed and transported by the conveying belt are almost simultaneously. It is known that the welding cutting device of the synthetic resin bag making machine is made so that only the cutting knife can be separated and replaced when the cutting knife is worn.

그러나, 이와같은 용착 절단장치는 하단에 2개위 용착날이 형성되고 그 상부에는 히터가 구비된 몸체의 주안부 즉, 상기 용착날의 사이에 일정깊이의 수직 삽입홈을 형성하고 그 삽입홈내에 일정폭과 길이를 가지는 하나의 절단칼이 끼워지게 구성한 것이며 이와같은 용착날 몸체와 절단칼은 그 재질이 상이한 금속제로 된 것이므로, 히터가 구동됨에 따라 용착날 몸체와 절단칼이 함께 가열되면 용착날 몸체와 절단칼이 각기 소폭 팽창하게 되는바, 이때에 용착날 몸체와 절단칼은 그 팽창률이 각각 다르므로 절단칼이 왜곡 변형되는 현상이 유발되이 요구되는 절단기능을 정확히 수행할수 없게 되는 단점을 갖게 될 뿐만 아니라, 이와같이 된 칼날이 반복 사용됨에 따라 그 칼날의 일부가 마모되거나 손상될 경우에는 그 절단칼 전체를 분리하여 새것으로 교체해햐만 하는 등의 비경제적인 문제점이 있었다.However, such a welding cutting device has two welding blades are formed at the bottom and a vertical insertion groove of a predetermined depth between the main portion of the body provided with a heater, that is, the welding blades, and a constant inside the insertion groove. Since the cutting blade body and the cutting knife are made of different metal materials, the welding blade body and the cutting knife are heated together with the welding blade body and the cutting knife when the heater is driven. And the cutting knife slightly expands. At this time, the welding blade body and the cutting knife have different expansion ratios, so that the cutting knife may be distorted and deformed. In addition, if the blade is worn or damaged as a result of repeated use, the entire cutting knife may be detached and replaced. There was an uneconomical problem such as replacing with.

본 고안은 상기와 같은 제반 단점 및 문제점을 감안하여 안출한 것으로, 하나의 절단칼을 일정폭과 길이를 가지는 다수개의 단위 칼편으로 분리 구성하고 이를 절단칼 고정부재에 연속 조립함으로써 절단칼이 가열됨에 따른 왜곡 변형 현상을 배제함과 아울러, 그 절단칼의 일부가 마모되거나 손상될 경우에는 그 손상부분에 해당하는 칼편만을 간단히 분리 교체할수 있게한 것인 바, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention was devised in view of the above-mentioned disadvantages and problems, and since one cutting knife is separated into a plurality of unit knife pieces having a predetermined width and length, and the cutting knife is heated by continuously assembling it to the cutting knife fixing member. In addition to excluding the distortion distortion phenomenon, when a part of the cutting knife is worn or damaged, it is possible to simply separate and replace only the knife piece corresponding to the damaged portion, which will be described in detail by the accompanying drawings As follows.
