Detailed Description of the Invention [Industrial applications]

The present invention relates to a device for producing insulating panels of different width and thickness.

[Prior art]

Conventionally, metal hoop materials such as colored zinc iron plate, colored aluminum plate, colored aluminum zinc alloy plated steel plate, stainless steel plate, titanium steel plate, etc. are carried into a double conveyor and a foamable resin material is injected between the metal hoop materials, Next, by heating the metal hoop material, the foamable resin material is foamed to fill the foamed resin layer between the metal hoop materials to manufacture the heat insulation panel. In this case, in order to prevent the foamable resin material from leaking to the outside between the side end portions of the upper and lower metal hoop materials when the foamable resin material foams, paper, synthetic resin or the like is used between the side end portions of the metal hoop material. Side conveyors are installed on both sides of the double conveyor to supply side seal materials such as sheets, metal foils, packing, etc., and to properly position and convey this side seal material between the side edges of the metal hoop material. The side seal pieces of the side conveyor are pressed against the side seal material by the side guides installed along both sides of the double conveyor, and the side seal material closes the side end portions of the metal hoop material to form a foamable resin material. Trying to prevent leaks. The side seal material is bonded and integrated with the foamed resin layer by the self-adhesive force of the foamable resin material. Insulation panels are manufactured in this way, but this type of insulation panel has a wall thickness of, for example, 22 mm, 35 mm, or 45 m.
There are various types such as m, 60 mm, 100 mm, and 120 mm, and these heat insulating panels having different wall thicknesses are manufactured by changing the vertical interval of the double conveyor and the thickness of the side seal pieces of the side conveyor.
