본 고안은 보온덮개의 성형작업시 형태가 변형되지 않도록 하고, 두께가 두꺼운 보온덮개의 성형작업도 한번에 이루어져 인력과 시간이 절감되도록 한 관체 보온덮개의 성형장치에 관한 것이다.The present invention is to prevent the deformation of the shape of the insulation cover during the molding operation, and the molding operation of the thick thermal insulation cover is also made at a time to reduce the manpower and time to the molding apparatus of the tubular insulation cover.

종래에는 평면상태의 보온덮개 원단에 적절히 열을 가한 다음 제 8 도에서와 같이 일측에 열풍관(86)이 형성된 나팔관형 성형틀(88)속으로 통과시키면 보온덮개 원단(90)이 원통형으로 성형되면서 양단부(92)(94)가 가열접착되고, 회전하는 양측 벨트(96)(98)사이에 끼워져 강제로 당겨져 나오게 한 것인데 이러한 성형장치는 가열성형된 보온덮개(90)가 완전히 냉각되기 전에 벨트(96)(98)사이에 끼워져 강제로 당겨지므로 제품의 형태가 변형되어 상품으로서의 가치가 떨어질 뿐 아니라 두께가 두꺼운 보온덮개(90)는 벨트(96)(98)의 압력으로 접착부위가 떨어지고 벌어져 불량이 되는 결점이 있었다.Conventionally, heat is applied appropriately to the heat insulating cover fabric in a planar state, and then the heat insulating cover fabric 90 is formed into a cylindrical shape by passing through a flap tube-shaped forming mold 88 having a hot air pipe 86 formed on one side as shown in FIG. Both ends 92 and 94 are heat-bonded and sandwiched between the two rotating belts 96 and 98 to be pulled out forcibly. Such a molding apparatus is a belt before the heat-molded insulating cover 90 is completely cooled. (96) (98) between the force is pulled, so that the shape of the product is not only deformed to reduce the value as a commodity, but also the thick heat insulating cover 90 is the adhesive area is dropped and opened by the pressure of the belt (96) (98) There was a fault which became a defect.

따라서 두께가 두꺼운 보온덮개를 제작하기 위하여는 두께가 얇은 보온덮개를 1차성형한 뒤 이를 다시 얇은 두께의 다른 보온덮개가 감싸도록 하여 2차성형 작업을 하는 방법으로 제작하여야 하므로 성형작업에 인력과 시간이 맣이 소모되는 등의 문제점이 있는 것이었다.Therefore, in order to manufacture a thick heat insulation cover, the thin heat insulation cover should be first molded and then the other heat insulation cover of thin thickness should be manufactured by a secondary molding operation. There was a problem such as the time wasted.

본 고안은 이러한 문제점을 해결하기 위하여 안출한 것으로서 작업대 위에서 좌우로 벌어져 열리고 닫히는 일정길이의 원통형 성형틀과 이 성형틀 내에 들어가고 성형틀보다 직경이 작은 성형봉에 의하여 보온덮개가 원통형으로 성형되며 성형된 보온덮개는 탈형되기 전에 그 양단부가 전열봉에 의하여 열접착된 후 탈형되도록 한 것이다.The present invention was devised to solve such a problem, and the insulating cover was formed into a cylindrical shape by a cylindrical molding mold having a predetermined length, which is opened and closed on the workbench, opened and closed on the workbench, and a molding rod having a smaller diameter than the molding mold. Insulating cover is to be demolded after both ends are heat-sealed by the heat-seal rod before demolding.
