[0045] A first aspect of the embodiments of the present application proposes a vacuum sealing machine 300 for vacuum insulation board 200, as shown in Figure 1 and Figure 2 As shown in Figure 1 schematically shows a structural schematic diagram of the vacuum sealing machine 300 for the vacuum insulation board 200 according to the embodiments of the present application (including the vacuum insulation board 200); Figure 2 for Figure 1A structure schematic view of the vacuum insulation board 200 shown in FIG. 1 in a second perspective view by the vacuum sealing machine 300. The vacuum sealing machine 300 is used to manufacture the vacuum insulation board 200, as shown in Figure 3 and Figure 4 Figure 3 A structure schematic view of the vacuum insulation board 200 according to the embodiment of the present application is schematically shown, Figure 4 Figure 3 A cross-sectional structure schematic view of the vacuum insulation board 200 shown in FIG. 1 along the A-A section. The vacuum insulation board 200 includes the filling core material 201, the getter 202 and the barrier bag 203, and the filling core material 201 and the getter 202 are put into the barrier bag 203 and then vacuumized and heat sealed. The processing of the vacuum insulation board 200 needs to be vacuumized and plastic sealed, etc. In the existing operation, the vacuum insulation board 200 is usually pushed into a closed space by manual operation, and when the vacuum degree meets the requirements, the sealing operation is manually performed. This processing method has low efficiency.

[0046] Continuing to refer to Figure 1 and Figure 2 In the present application, the vacuum sealing machine 300 is used to realize the manufacturing of the vacuum insulation board 200. The vacuum sealing machine 300 includes a vacuum heat sealing assembly 3, which includes a vacuumizing part 31 and a heat sealing part 32. The vacuumizing part 31 is provided with an air exhaust pipe 311, which is used to communicate with the inside of the barrier bag 203 and can perform the vacuumizing operation on the inside of the barrier bag 203. The heat sealing part 32 includes oppositely arranged first and second heat sealing structures 321 and 322, which can be close to each other to heat seal the opening 2031 of the barrier bag 203 on the opposite sides of the opening 2031.

[0047] The vacuumizing part 31 can be a vacuumizing pump or other products, which can directly perform the vacuumizing operation on the inside of the barrier bag 203. The vacuumizing part 31 can be connected with the heat sealing part 32. At this time, the heat sealing part 32 and the vacuumizing part 31 are connected in a detachable manner or in a fixed connection manner. Alternatively, the heat sealing part 32 and the vacuumizing part 31 can also have independent structures to realize the functions of heat sealing and vacuumizing, respectively.

[0048] The first and second heat sealing structures 321 and 322 are spaced apart along the height direction of the vacuum sealing machine 300, that is, the first and second heat sealing structures 321 and 322 are spaced apart along the Z-Z direction in Figure 1 , wherein the Z-Z direction is the height direction of the vacuum sealing machine 300, Figure 1 the X-X direction in Figure 2 ​​The YY direction in the diagram refers to the width direction of the vacuum sealing machine 300. The first heat-sealing structure 321 can heat-seal the opening 2031 from opposite sides. The second heat-sealing structure 322 can heat-seal the opening 2031 from opposite sides.

[0049] In addition, the number of vacuum heat sealing components 3 here can be one. That is to say, the number of vacuuming components 31 and heat sealing components 32 is one. Vacuuming components 31 are used to evacuate the inside of the barrier bag 203. After the vacuum degree inside the barrier bag 203 reaches the required level, the opening 2031 of the barrier bag 203 is heat sealed by the heat sealing components 32, thereby completing the production of the vacuum insulation board 200.

[0050] Alternatively, such as Figure 1 As shown, there can also be two vacuum heat-sealing components 3, arranged opposite to each other. In this case, the number of openings 2031 in the barrier bag 203 is also two. Each vacuum heat-sealing component 3 evacuates the barrier bag 203 from one opening 2031, extracting air from two positions in the barrier bag 203. This can quickly reduce the internal air pressure of the large-sized barrier bag 203, thereby reducing the thermal conductivity of the manufactured vacuum insulation board 200. In this embodiment, since the barrier bag 203 can have at least two openings 2031 pre-set to achieve convection, the gas inside the barrier bag 203 can be extracted more quickly.

[0051] Alternatively, there can be three or more vacuum heat-sealing components 3. By using a larger number of vacuum heat-sealing components 3 to evacuate the barrier bag 203, the vacuuming efficiency of the large-sized barrier bag 203 can be improved. Considering that the vacuum heat-sealing components 3 can be adjusted according to the position of the opening 2031 of the barrier bag 203, the vacuum heat-sealing components 3 can be moved as needed to achieve sequential heat sealing of the opening 2031 of the barrier bag 203.

[0052] According to the vacuum sealing machine 300, the vacuum heat sealing assembly 3 comprising the vacuumizing part 31 and the heat sealing part 32 is arranged, the vacuumizing part 31 is provided with the air exhaust pipe 311, the air exhaust pipe 311 is communicated with the inside of the barrier bag 203 and is used for vacuumizing the inside of the barrier bag 203, the heat sealing part 32 comprises the first heat sealing structure 321 and the second heat sealing structure 322 which are oppositely arranged, the first heat sealing structure 321 and the second heat sealing structure 322 can be close to each other and realize heat sealing of the opening 2031 of the barrier bag 203, then the inside of the barrier bag 203 can be vacuumized through the air exhaust pipe 311 of the vacuumizing part 31, when the vacuum degree of the inside of the barrier bag 203 meets the requirement, the heat sealing of the opening 2031 of the barrier bag 203 is realized through the cooperation of the first heat sealing structure 321 and the second heat sealing structure 322, thereby the production of the vacuum insulation board 200 is completed, the automatic production of the vacuum insulation board 200 can be realized, and the production efficiency of the vacuum insulation board 200 is improved.

[0053] It should be noted that the vacuum degree of the inside of the barrier bag 203 meeting the requirement can be determined according to the vacuumizing time, for example, it can be considered that the vacuum degree of the inside of the barrier bag 203 meets the requirement after the vacuum heat sealing assembly 3 is vacuumized for a certain time, specifically, it can be considered that the vacuum degree of the inside of the barrier bag 203 meets the requirement after the vacuum heat sealing assembly 3 is vacuumized for 10 minutes or 20 minutes; the vacuum degree of the inside of the barrier bag 203 meeting the requirement can also be determined according to the vacuum degree detection of the inside of the barrier bag 203, for example, the vacuum degree meeting the requirement can be less than or equal to 1Pa, also can be less than or equal to 0.5Pa, also can be less than or equal to 0.05Pa, the specific vacuum degree can be detected by a vacuum detector, also can be detected by a power frequency withstand voltage method, whether the requirement is met can be determined according to the requirement of the vacuum degree of the vacuum insulation board 200.

[0054] Optionally, as shown in Figure 1 and Figure 2 When the number of the vacuum heat sealing assembly 3 is two or more, and at least two vacuum heat sealing assemblies 3 are arranged on the opposite sides of the barrier bag 203 along the length direction or the width direction, the side of the barrier bag 203 facing the vacuum heat sealing assembly 3 is provided with the opening 2031, that is, the number of the vacuum heat sealing assembly 3 is multiple, the efficiency of vacuumizing the inside of the barrier bag 203 can be improved.

[0055] It should be noted that the present embodiment is for the case that the barrier bag 203 is of a rectangular structure, and the rectangular structure barrier bag 203 has a clear length direction or width direction. When the barrier bag 203 is of a hexagonal or pentagonal star-shaped or other special-shaped structure, there is no obvious length direction or width direction, and in the present embodiment, the two vacuum heat sealing assemblies 3 are arranged at two non-adjacent sides of the barrier bag 203.

[0056] In some embodiments of the present application, as shown in Figure 1 and Figure 2 The vacuum sealing machine 300 further comprises a pressing plate assembly 4 arranged at one side of the vacuum heat sealing assembly 3 and used for placing the barrier bag 203 with the filling core material 201 arranged inside.

[0057] Specifically, the barrier bag 203 can be placed in the internal space of the pressing plate assembly 4, and the opening 2031 of the barrier bag 203 is located outside the pressing plate assembly 4, thereby reducing the influence of the pressing plate assembly 4 on the heat sealing process of the opening 2031.

[0058] Specifically, the pressing plate assembly 4 comprises a first pressing plate 41 and a second pressing plate 42 arranged oppositely, one of the first pressing plate 41 and the second pressing plate 42 is used for placing the barrier bag 203 with the filling core material 201 arranged inside, and the other of the first pressing plate 41 and the second pressing plate 42 can generate a movement close to the barrier bag 203 to compress the barrier bag 203 with the filling core material 201 arranged inside.

Here, the first pressing plate 41 can be located above the second pressing plate 42, and the first pressing plate 41 can also be located below the second pressing plate 42, and here the first pressing plate 41 located above the second pressing plate 42 is described in detail.

[0060] It should be noted that the opening 2031 of the barrier bag 203 can be arranged in suspension, or a support plate (not shown) flush with the surface of the second pressing plate 42 can be arranged below the opening 2031 of the barrier bag 203, and the support plate can support part of the opening 2031 of the barrier bag 203, and through the joint action of the second pressing plate 42 and the support plate, the support of the barrier bag 203 is realized, wherein the support plate will not affect the sealing process of the heat sealing element 32.

In addition, the vacuum sealing machine 300 is provided with the first pressing plate 41 and the second pressing plate 42, so that the upper surface of the barrier bag 203 is in contact with the first pressing plate 41 and the lower surface of the barrier bag 203 is in contact with the second pressing plate 42 during vacuumizing, which can inhibit the shrinkage of the barrier bag 203 on the surface of the filling core material 201 during the air extraction process, and improve the surface flatness of the vacuum insulation panel 200.

[0062] In some embodiments of the present application, as shown in Figure 1 At least one of the first pressing plate 41 and the second pressing plate 42 is provided with a heating element 43.
