Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation technology, and in particular to a novel vacuum insulation panel. Background Technology

[0002] Vacuum insulation panels consist of four parts: core material, desiccant, getter, and high-barrier film. The high-barrier film effectively prevents gas heat transfer by maintaining a high vacuum inside to the maximum extent, thereby achieving efficient heat insulation.

[0003] Traditional methods for manufacturing vacuum insulation panels typically involve first creating an open barrier bag from a high-barrier film, then filling the bag with the core material, desiccant, and getter through the opening, and finally heat-sealing the bag after vacuuming. Traditional barrier bags have relatively large openings, facilitating the filling of the core material. However, after heat sealing, the edges are quite large, requiring folding. This folding process is cumbersome and also wastes a significant amount of high-barrier film.

[0004] To address this issue, patent application number 2020100026204 discloses an invisible edge-sealed packaging bag for vacuum insulation panels. This bag includes an aluminum foil film, with both the inner and outer layers having heat-sealing layers, or both layers being heat-sealing. An invisible edge-sealed aluminum foil bag is formed by heat-pressing one end of the aluminum foil film to the other, creating the seal. This makes the seal an integral part of the bag, invisible from the outside, resulting in a more aesthetically pleasing appearance. It also saves on materials and reduces manufacturing costs. When packaging vacuum insulation panels, only two sides need to be folded, increasing folding efficiency and reducing labor costs. However, a drawback is that the small opening of the barrier bag makes the core material filling process somewhat inconvenient. Utility Model Content

[0005] Based on the above-mentioned problems in the prior art, the purpose of this application is to provide a novel vacuum insulation panel, which facilitates the loading of the core material into the barrier bag by setting a guide part at the opening of the barrier bag, making the bagging process more convenient.

[0006] The technical solution adopted by this application to solve its technical problem is: a new type of vacuum insulation panel, including a barrier bag, a core material, a getter and a desiccant;

[0007] The barrier bag has a guide portion at its opening, the diameter of which gradually increases from near the opening to far away from the opening. The core material is placed inside the barrier bag through the guide portion. The getter is placed on the core material and located inside the barrier bag. The desiccant is placed on the core material and located inside the barrier bag.

[0008] Furthermore, the barrier bag is a barrier bag formed by heat-sealing the end-to-end joints of a barrier film. A first heat-sealing layer is provided on the upper surface of the barrier film, and a second heat-sealing layer is provided on the lower surface of the barrier film, which overlaps with the first heat-sealing layer.

[0009] Furthermore, the first heat-sealing layer and the second heat-sealing layer are PE layers.

[0010] Furthermore, the guide portion is an integrally formed guide flare at the opening position of the barrier bag.

[0011] Furthermore, the guide portion is a guide member, which includes an insertion section and a guide section. The insertion section is disposed inside the opening of the barrier bag, and the guide section is integrally formed with the insertion section. The diameter of the guide section gradually increases from the direction closer to the opening to the direction farther away from the opening.

[0012] Furthermore, the core material is a rigid foam core material.

[0013] Furthermore, the core material is polyurethane open-cell foam core material, polystyrene open-cell foam core material, or phenolic open-cell foam core material.

[0014] The beneficial effects of this application are as follows: The barrier bag of the novel vacuum insulation panel has a guide portion at its opening. When the core material is bagged, it is inserted into the barrier bag along the guide portion. Since the diameter of the guide portion gradually increases from near the opening to far away from the opening, it is convenient to insert the core material into the barrier bag. A receiving cavity for the core material is formed inside the barrier bag. The width of the receiving cavity is equal to or slightly greater than the width of the core material, and the height of the receiving cavity is equal to or slightly greater than the thickness of the core material. As a result, after the core material is bagged, the left and right sides of the core material are close to the left and right inner walls of the barrier bag, and the top and bottom sides of the core material are close to the top and bottom inner walls of the barrier bag. This means that the vacuum insulation panel produced does not need to be folded on the left and right sides; only the front and back sides need to be folded, which is efficient.

[0021] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 4 As shown, a novel vacuum insulation panel of this utility model includes a barrier bag 1, a core material 2, a getter 3, and a desiccant 4. The opening of the barrier bag 1 is provided with a guide part 11, the diameter of which gradually increases from near the opening to far away from the opening. The core material 2 is disposed inside the barrier bag 1 through the guide part 11. The getter 3 is disposed on the core material 2 and located inside the barrier bag 1. The desiccant 4 is disposed on the core material 2 and located inside the barrier bag 1.

[0023] Thus, this utility model relates to a novel vacuum insulation panel. The opening of the barrier bag 1 of this novel vacuum insulation panel is provided with a guide portion 11. When the core material 2 is bagged, the core material 2 is inserted into the barrier bag 1 along the guide portion 11. Since the diameter of the guide portion 11 gradually increases from near the opening to far away from the opening, it is convenient to insert the core material 2 into the barrier bag 1. A receiving cavity for accommodating the core material 2 is formed inside the barrier bag 1. The width of the receiving cavity is equal to or slightly greater than the width of the core material 2, and the height of the receiving cavity is equal to or slightly greater than the thickness of the core material 2. Thus, after the core material 2 is bagged, the left and right sides of the core material 2 are close to the left and right inner sidewalls of the barrier bag 1, and the upper and lower sides of the core material 2 are close to the upper and lower inner sidewalls of the barrier bag 1. Therefore, the left and right sides of the manufactured vacuum insulation panel do not need to be folded, and only the front and back sides need to be folded, which is efficient.

[0024] In a preferred embodiment of this invention, the barrier bag 1 is formed by heat-sealing the end of a barrier film 5. A first heat-sealing layer 51 is provided on the upper surface of the barrier film 5, and a second heat-sealing layer 52, which overlaps with the first heat-sealing layer 51, is provided on the lower surface of the barrier film 5. Specifically, the first heat-sealing layer 51 and the second heat-sealing layer 52 are PE layers. When preparing the barrier bag 1, the end of the barrier film 5 is overlapped so that the second heat-sealing layer 52 overlaps the first heat-sealing layer 51. Then, heating is applied to heat-seal the second heat-sealing layer 52 and the first heat-sealing layer 51 together to form a cylindrical barrier tube. Then, one end of the cylindrical barrier tube is heat-sealed to form a seal, and the other end of the cylindrical barrier tube is expanded to form a flared opening. The barrier film 5 is an aluminum-free barrier film 5 to facilitate the expansion of the flared end of the cylindrical barrier tube.

[0025] In this embodiment, a receiving cavity is formed inside the barrier bag 1. The width of the receiving cavity is equal to the width of the core material 2, and the height of the receiving cavity is equal to the thickness of the core material 2. Alternatively, the width of the receiving cavity is slightly greater than the width of the core material 2, and the height of the receiving cavity is slightly greater than the thickness of the core material 2. Thus, after the core material 2 is inserted into the receiving cavity inside the barrier bag 1, the left and right sides of the core material 2 are adjacent to the left and right inner sidewalls of the barrier bag 1, and the top and bottom sides of the core material 2 are adjacent to the top and bottom inner sidewalls of the barrier bag 1, achieving the goal of only folding the front and back edges of the vacuum insulation board.

[0026] like Figure 1 As shown, in a preferred embodiment, the guide portion 11 is a guide flare 111 integrally formed at the opening position of the barrier bag 1, which is formed by expanding the end of the cylindrical barrier tube.

[0027] like Figure 2 As shown, in some embodiments, the guide portion 11 is a guide member 112, which includes an insertion section 1121 and a guide section 1122. The insertion section 1121 is disposed inside the opening of the barrier bag 1, and the guide section 1122 is integrally formed with the insertion section 1121. The diameter of the guide section 1122 gradually increases from near the opening to away from the opening. During bagging, the insertion section 1121 is inserted into the opening of the barrier bag 1 to facilitate the core material 2 to be bagged through the guide section 1122.

[0028] In this embodiment, the core material 2 is a rigid foam core material. After the rigid foam core material is bagged, its compression ratio is low, making it less likely for flash to form on the left and right sides of the vacuum insulation panel, thus eliminating the need for folding edges on the left and right sides of the vacuum insulation panel. Specifically, the core material 2 is a polyurethane open-cell foam core material, a polystyrene open-cell foam core material, or a phenolic open-cell foam core material.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
