Embodiment 1

[0048] The manufacturing method of the overall vacuum insulation box described in this embodiment comprises the following steps:

[0049] (1) Prepare a small barrier bag with an opening at one end and a large barrier bag with two ends open. The large and small barrier bags are made of barrier film. Insert the small barrier bag 7 into the large barrier bag 6, with the upper port flush and centered , the outside of the upper port of the small barrier bag 7 is heat-sealed with the inner surface of the upper port of the large barrier bag 6, and the seal is 5 to form an inner jacket barrier bag, such as figure 1 shown;

[0050] (2) Make a model, the outer dimensions of model 1 are the same as the inner dimensions of the insulation box;

[0051] (3) Stretch the opening of the barrier bag of the inner jacket made in step (1), and put the model 1 into the small barrier bag 7;

[0052] (4) Put the heat-insulating core material 3 from the other pocket of the large barrier bag into the...

Embodiment 2

[0058] A method for manufacturing an integral vacuum insulation box described in this embodiment includes the following steps:

[0059] (1) Make model 1 with the same size as the required box;

[0060] (2) In the atmospheric environment, put the model into a barrier bag, which is a bag made of barrier film 2, and make the barrier bag fit the surface of model 1 through shaping;

[0061] (3) Wrap the heat insulation core material 3 with the same size as that of each side of the model on the outer side and bottom of the barrier bag, such as image 3 shown;

[0062] (4) Wrap the insulation core material 3 inside the barrier bag and fix it;

[0063] (5) Send it into the vacuum sealing box to vacuumize and seal the barrier bag;

[0064] (6) Move the product to the atmosphere, fold and reshape the barrier bag, such as Figure 4 shown;

[0065] (7) Take out the model.

[0066] In the overall vacuum insulation box described in this embodiment, the box body is wrapped by the same ba...

Embodiment 3

[0068] A method for manufacturing an integral vacuum insulation box described in this embodiment includes the following steps:

[0069] (1) The heat insulation core material 3 is made into a box shape with one end open by pressing, pouring, and splicing, such as Figure 5 shown;

[0070] (2) In the atmospheric environment, put the barrier film 2 into the box that has been made, and spread the barrier film 2 evenly on the inner and bottom surfaces of the box, such as Image 6 shown;

[0071] (3) Turn the barrier film 2 outward along the opening of the box to wrap the outer side and bottom of the box, such as Figure 7 shown;

[0072] (4) Send it into the vacuum sealing box to evacuate and seal the barrier film;

[0073] (5) Move the product to the atmosphere, and fold and shape the barrier film 2 .

[0074] In the overall vacuum insulation box described in this embodiment, the box body is made first, and the box body is wrapped by the same barrier film 2, and the heat insu...

Abstract

The invention discloses an integral vacuum heat insulation box and a manufacturing method of the integral vacuum heat insulation box. Blocking films cover the inside and the outside of a box body in a vacuum state, the inside of the blocking films is filled with heat insulation core materials, and the outer side of the box body is provided with a vacuum pumping opening. The integral vacuum heat insulation box and the manufacturing method adopt a major principle that the box body is covered by blocking materials, core materials of each surface and each corner part of the box body are respectively in the same vacuum state, the defect of heat insulation performance reduction generated at the box body splicing part when other methods such as splicing, foam fixation and gluewater fixation are adopted is effectively avoided, the three methods can respectively reach the requirements, a bag does not need to turn in a large amplitude according to the first method, the excessive deformation of the blocking bag is reduced, the fracture and the breaking of the blocking bag are avoided, and the breaking rate of a product is reduced by more than 80 percent. The integral vacuum heat insulation box manufactured by adopting the manufacturing method provided by the invention has the advantages that the heat insulation performance is stable, and the use effect is good.

Description

technical field [0001] The invention belongs to the technical field of vacuum heat insulation boxes, and in particular relates to an integral vacuum heat insulation box and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, in the field of storage and transportation of items, the requirements for the thermal insulation performance of items are getting higher and higher, such as the storage and transportation of medicines and fresh food, it is necessary to improve the thermal insulation performance and reduce the volume of the thermal insulation box to extend the Heat preservation time, extend the transportation distance. In this context, the application of vacuum insulation technology (referred to as VIP) has gradually been widely concerned and used. Although the VIP board has the advantages of better thermal insulation performance and smaller volume than traditional thermal insulation materials, when it ...
