[0003] Existing problems: In the field of vacuum heat sealing, it is found that the vacuum insulation panels prepared by the above-mentioned device have a certain ratio and interlayer misalignment will occur, resulting in the prepared vacuum insulation panels not having a regular rectangular structure, while refrigerators and other household appliances are all regular shapes. It is required that the vacuum insulation panels also have a regular rectangular structure
Once the vacuum insulation panel is heat-sealed, it is difficult to change its shape.

Abstract
Aiming at the problem of misplacement of core materials in the horizontal vacuum heat sealing process of a vacuum heat insulation plate, the invention discloses a vertical vacuum heat sealing device and a vertical vacuum heat sealing method for the vacuum heat insulation plate. The vertical vacuum heat sealing device comprises a vacuum chamber, a vacuum system, a vacuum meter, a heat sealing strip, a sample stage and a reciprocating mechanism and is characterized in that both the heat sealing strip and the sample stage are of vertical structures; by the vertical structure of the sample stage, under the action of gravity, the core materials are neatly positioned at one side of a sealing bag, so that the problem of influence of gas flowing on the positions of the core materials in the vacuumizing process is solved; in the same way, the heat sealing strip with the vertical structure is adopted to carry out vacuum heat sealing packaging on the vacuum heat insulation plate, and finally the vacuum heat insulation plate with regular appearance is obtained.
Description
technical field [0001] The invention relates to a vacuum heat-sealing device and method for a vacuum insulation panel, in particular to a vertical vacuum heat-sealing device and method for a vacuum insulation panel. Background technique [0002] The vacuum insulation panel adopts the principle of vacuum insulation, and the air in the insulation space needs to be evacuated to remove it, so that it has an extremely low thermal conductivity. The vacuum heat-sealing device is a device for vacuum heat-sealing the vacuum insulation board. The common heat-sealing device is a horizontal structure, that is, the sample table and the heat-sealing strip are both horizontal, and the vacuum insulation board is placed on the sample table horizontally. The system is evacuated to the required degree of vacuum, and then vacuum heat-sealed by the upper and lower heat-sealing strips. The core material of the vacuum insulation panel is often stacked by 6-10 pieces of wet-laid glass wool core ma...
