Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation board processing, in particular to a covering auxiliary device for a vacuum heat insulation board. Background Art

[0002] Vacuum Insulation Panel is one of the most efficient thermal insulation materials with excellent thermal insulation performance. It uses the vacuum process to keep the internal core material in a vacuum state, effectively avoiding heat transfer caused by air convection. Through other special structures and process designs, the thermal conduction and thermal radiation of the material are reduced to the lowest level. The thermal conductivity can be as low as 1.5mW / (m 2 K), which is only one tenth of traditional insulation materials. Under the same insulation technical requirements, vacuum insulation panels have the advantages of thin thickness, small volume, and light weight. Since its development, they have been actively developed and applied in many fields such as aerospace, building exterior walls, household appliances, cold chain logistics, etc.

[0003] The core material of the vacuum insulation panel is a rectangular block formed by compacting, cutting, and trimming powders of fumed silica and inorganic fibers. The thickness varies from 10 to 40 mm, and the length and width vary from 100 to 600 mm. In order to facilitate the subsequent installation of barrier bags, vacuuming, barrier bag folding and sealing, the core board must be wrapped (coated) with non-woven fabric.

[0004] However, since the core board is fragile, it is not possible to make a bag with non-woven fabric in advance and then fill it with the core board. Currently, the only way is to manually wrap the non-woven fabric on the surface of the core board and then use an electric soldering iron to hot-melt weld and seal the edges. This method is inefficient and easily causes the core board to break. In addition, there is no structural support during welding, and the weld cannot be guaranteed to be smooth.
