본 발명은 압출기의 성형다이를 통해서 성형된 열 회복성, 시트를 일정 폭으로 넓게 연신시켜 주는 연신장치에 관한 것으로, 특히 제조되는 열 회복성, 시트를 상, 하 간극조절과 연식각도를 자유자재로 조정할 수 있도록 한 두쌍의 캐터필러의 외면에 설치시킨 테프론 벨트 사이로 양단을 동시에 물리게 하여 연신작업을 연속적으로 수행하면서 수축도 방지할 수 있도록 한 열 회복성 시트의 연신장치에 관한 것이다.The present invention relates to an apparatus for stretching heat, which is formed through a molding die of an extruder, and a sheet for stretching a sheet to a predetermined width. It relates to an apparatus for stretching a heat recoverable sheet, by which both ends are simultaneously pinched between Teflon belts installed on the outer surface of a pair of caterpillars so as to be adjusted by the same.

일반적으로, 제조라인에서 제조된 시트는 압출기의 성형다이를 통해 일정 폭으로 넓게 연신시키게 되는데 종래에는 시트의 일측단만을 잡아 한쪽 방향으로 연신시켜 주는 배치(Batch)식이 이용되었기 때문에 편심 수축이 일어나게 된다.In general, the sheet produced in the manufacturing line is stretched to a wide width through a molding die of the extruder, but in the conventional eccentric shrinkage occurs because a batch (batch) formula is used to hold only one end of the sheet and stretch it in one direction. .

즉, 연신되는 방향으로부터 직각으로 수축이 발생하게 되어 제품의 품질을 저하시키게 되며 수축이 심하게 발생하는 경우에는 제조된 시트 자체를 불량처리 할 수밖에 없으므로써 매우 비경제적이었으며, 이와 같은 종래의 방법으로는 연속연신작업이 불가능하였으며, 특히 시트의 두께에 따른 연신작업시 호환성이 불량하고, 연신률(연신넓이)를 임의대로 조절하기가 불가능한 등의 많은 폐단이 있었다.In other words, shrinkage occurs at right angles from the direction of drawing, which reduces the quality of the product, and in the case of severe shrinkage, it is very uneconomical because the sheet itself has to be treated poorly. Continuous stretching was not possible, and in particular, there were many closures such as incompatibility during the stretching operation according to the thickness of the sheet, and it was impossible to arbitrarily adjust the stretching ratio (stretching width).

따라서, 본 발명은 상기와 같은 종래의 문제점을 해소키 위해 상, 하 간극조절과 연신넓이를 자유자재로 조정할 수 있는 두쌍의 캐터필러를 이용하여 시트의 양단을 동시에 잡고 연신작업을 연속적으로 수행할 수 있도록 하는 한편, 시트두께와 연신률의 임의 조절이 가능토록 한 열 회복성 시트의 연시장치를 제공키 위한 것으로, 이하 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention can simultaneously perform the stretching operation by holding both ends of the sheet at the same time by using two pairs of caterpillars that can freely adjust the upper and lower clearance gap and the stretching width to solve the above conventional problems. On the other hand, to provide an annual market value of the heat recoverable sheet to be able to arbitrarily control the sheet thickness and elongation, the present invention will be described in detail by the accompanying drawings as follows.

본 발명의 구성을 크게 나누어 보면 제 1 도에서 보는 바와 같이 가교된 시트(2)를 감고 있는 보빈(3)이 전방에 설치되고 이어 이송로울러(4)(4') 및 가교된 시트(2)를 연속적으로 가열하는 히터(5) 그리고 가열된 시트(2')를 연속적으로 연신시켜 주는 연신장치(6)(6')가 순차적으로 설치되며 이의 후방부에는 연신된 열 회복성 시트(2'')를 냉각시키면서 권취기(8)로 보내주는 냉각로울러(7)(7')가 설치구성된다.When the structure of the present invention is largely divided, as shown in FIG. 1, the bobbin 3 winding the crosslinked sheet 2 is installed in front, and then the transfer rollers 4, 4 'and the crosslinked sheet 2 are installed. Heater 5 for continuously heating and stretching apparatuses 6 and 6 'for continuously stretching the heated sheet 2' are sequentially installed, and at the rear thereof, the stretched heat recoverable sheet 2 '. Cooling rollers (7) (7 ') for cooling the') to the winder (8) are installed.

이를 더욱 상세히 설명하면, 제 2 도에서 보는 바와 같이 연신장치(6)(6')의 내부에는 두쌍의 캐피필러(9)(9')가 설치되고 캐터필러(9)(9')외부 둘레이는 테프론 벨트(10)(10')를 접설시켜 상기 테프론 벨트(10)(10') 사이에 물리는 열 회복성 시트(2)를 견고하게 잡아 이송시킬 수 있도록 하고, 두쌍의 캐터필터(9)(9')를 가지는 연신장치(6)(6')의 외부상단에는 간극조절 손잡이(11)(11')(11'')(11''')를 설치하여 두쌍의 캐터필러(9)(9') 간격을 제 4 도에서 보는 바와 같이 임의조정 가능토록 구성하되, 상기 연신장치(6)(6')는 제 5 도에서 보는 바와 같이 일측 힌지핀(12)(12')을 힌지점으로하여 벌어지는 각도(연신넓이)를 임의대로 조절할 수 있게 설치구성된 것이다.In more detail, as shown in FIG. 2, two pairs of capillaries 9 and 9 ′ are installed inside the drawing apparatus 6 and 6 ′, and the outer periphery of the caterpillars 9 and 9 ′ Teflon belts 10 and 10 'are attached to each other so that the heat recoverable sheet 2 sandwiched between the Teflon belts 10 and 10' can be firmly gripped and conveyed, and the two pairs of caterpillar filters 9 ( A gap adjusting knob (11) (11 ') (11' ', 11' '') is provided on the outer upper end of the drawing device (6) (6 ') having two pairs of caterpillars (9) (9'). ') The interval is configured to be arbitrarily adjustable as shown in FIG. 4, wherein the stretching device 6, 6' has one hinge pin 12, 12 'as a hinge point as shown in FIG. It is installed to be able to adjust the angle (stretching width) to open arbitrarily.

미 설명부호(13)은 받침로울러 임.Unexplained reference numeral 13 is a support roller.

이상과 같이 구성된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.

먼저, 압출기 성형다이(도시생략)를 통해 성형된 열 회복성 시트(2)를 본 고안장치(1)의 전방부 보빈(3)에 감아 가교시킨 다음 열 회복성 시트(2)를 이송로울러(4)(4') 사이에 물려 이송시키면서 히터(5)를 통해 연속적으로 가열시키고, 상기 공정에서 가열된 시트(2')는 양측에 경사지게 설치된 연신장치(6)(6') 내부의 두쌍의 캐터필러(9)(9') 선단에 물려주면, 공지모터(도시되지 않음) 동작에 의해서 테프론 벨트(10)(10')로 접설되어 있는 캐터필러(9)(9')가 회전하면서 가열된 시트(2')를 물고 회전하게 되어 열 회복성 시트(2)를 일정각도만큼 점차적으로 넓게 연신시키면서 이동하게 되는 바, 이때 상기 연신장치(6)(6') 내부의 두쌍의 캐터필러(9)(9') 간격은 시트(2) 두께에 따라 외부 손잡이(11)(11')(11'')(11''')를 조절하는 것이며, 상기 히터(5)에서 가열된 시트(2')가 연신장치(6)(6')에 의해 일정 넓이로 연신된 후 연신장치(6)(6')의 뒷편 냉각 로울러(7)(7') 사이를 통과함에 따라 완성된 열 수축성 시트(2''')로 변화되어 공지의 권취기(8)에 권취되므로써 비로소 그 제조공정이 완료되는 것이다.First, the heat recoverable sheet 2 formed through an extruder molding die (not shown) is wound around the front bobbin 3 of the present invention device 1 and crosslinked, and then the heat recoverable sheet 2 is transferred to a roller ( 4) Continuously heating through the heater 5 while being transferred between (4 '), the sheet 2' heated in the process is a pair of two inside the stretching device (6) (6 ') installed inclined on both sides. The sheet is heated by rotating the caterpillar 9, 9 'which is connected to the Teflon belt 10, 10' by a known motor (not shown) by rotating it at the tip of the caterpillar 9, 9 '. (2 ') is rotated to move the heat recoverable sheet (2) by gradually extending the heat recovery sheet 2 by a predetermined angle, at this time, the two pairs of caterpillar (9) in the stretching device (6) (6') ( 9 ') spacing is to adjust the outer handles 11, 11', 11 " and 11 '" according to the sheet 2 thickness, and the sheet 2' heated in the heater 5 Autumn kite Completed heat shrinkable sheet 2 '' as it is stretched to a certain extent by the devices 6, 6 'and then passed between the cooling rollers 7, 7' at the rear of the drawing device 6, 6 '. The manufacturing process is completed only when it is changed to ") and wound up by the well-known winding machine 8.

즉, 이송로울러(4)(4')와 연신장치(6)(6')의 내부 캐터필러(9)(9') 그리고 뒷편의 냉각로울러(7)(7')에 의해서 연속적으로 이송연신되면서 열 수축성 시트(2''')가 제조완성되는 것이며, 연신장치(6)(6')의 설치 각도를 임의대로 조절함에 따라 시트(2)의 연신넓이(연신률)를 다양하게 조정할 수 있음을 물론, 연신장치(6)(6')의 내부에 설치된 두쌍의 캐터필러(9)(9') 상, 하 간극을 손잡이(11)(11')(11'')(11''')에 의해서 임의대로 조정할 수 있게 되므로써 두께가 다른 여러종류의 시트를 연신시킬 수 있게 되는 것이다.That is, while continuously conveyed and stretched by the transfer rollers 4, 4 ', the inner caterpillars 9, 9' of the stretching apparatuses 6, 6 ', and the cooling rollers 7, 7' of the rear side. The heat shrinkable sheet 2 '' 'is manufactured, and the drawing width (elongation) of the sheet 2 can be variously adjusted by arbitrarily adjusting the installation angle of the stretching device 6, 6'. Of course, the upper and lower gaps of the two pairs of caterpillars 9, 9 'provided inside the stretching apparatus 6, 6' are attached to the handles 11, 11 ', 11' ', 11' ''. By being able to adjust arbitrarily by this, it becomes possible to extend | stretch various types of sheets from which thickness differs.

이상에서 상술한 바와 같이, 본 발명에 의하면 연신작업의 호환성이 높아 여러종류의 열 회복성 시트를 다양한 연신률로 연신시킬 수 있어 작업능률이 향상될 뿐 아니라, 연신작업시 시트의 양단을 동시에 잡아 연신시키므로써 연신시 발생하는 직각방향으로의 수축을 방지하여 제품의 품질을 향상시킬 수 있는 이점이 있으며, 불량발생률의 염려가 배제됨에 따라 경제적 효과를 득할 수 있는 한편, 특히 연신작업을 연속적으로 수행할 수 있어 생산성을 대폭 향상시킬 수 있는 등의 매우 획기적인 열 회복성 시트의 연신장치를 제공할 수 있는 것이다.As described above, according to the present invention, the compatibility of the stretching operation is high, so that various types of heat recoverable sheets can be stretched at various elongation rates, thereby improving work efficiency, and simultaneously stretching both ends of the sheet during the stretching operation. It is possible to prevent the shrinkage in the direction perpendicular to the product generated by the stretching, thereby improving the quality of the product, economic benefits can be obtained by eliminating the concern about the failure rate, while in particular to perform the stretching operation continuously It is possible to provide a very innovative heat recovering sheet stretching apparatus, such as that can significantly improve productivity.
