Description

A vacuum packaging device

technical field

The utility model relates to the field of packaging devices, in particular to a vacuum packaging device.

Background technique

At present, the packaging of fragile or valuable items is usually accompanied by the use of foam plastics in the packaging box for cushioning and safety protection of the items, and a desiccant bag is placed in the packaging box for moisture-proof protection. The existing packaging of this kind of packing box has a certain effect in terms of moisture-proof and anti-collision buffer protection, but the fixing stability of the foamed plastic is not enough, and the desiccant is packaged in a relatively humid environment, and the desiccant is easy to absorb water and saturate, and the drying effect is average. , especially the packaging of valuables such as precision instruments that cannot meet the high requirements of moisture-proof and anti-collision protection.

Utility model content

The purpose of the utility model is to provide a vacuum packaging device with good stability in anti-collision buffer protection and good drying effect, so as to overcome the deficiencies in the prior art.

A vacuum packaging device designed for this purpose includes a vacuum-pumpable sealed box, the sealed box includes a connected upper cover and a lower box, and one or more elastic airbags are arranged in the lower box.

Further, the upper cover is provided with an air extraction hole, and a sealing check valve is arranged in the air extraction hole.

Further, an air release valve is provided on the upper cover.

Further, an elastic seal is provided between the upper cover and the lower case.

When the vacuum packaging device of the present invention is in use, the object to be packaged is put into the lower box, and the object is placed in the middle of the elastic air bag, then the upper cover is fastened on the lower box, and then the vacuum pump is used to remove the object. Vacuumize the sealed box to make the inside of the box negative pressure, because the air pressure in the elastic airbag is greater than the air pressure in the sealed box, the elastic airbag will expand and bulge, and then wrap the object in the middle of the elastic airbag, and because the elastic airbag itself It is elastic and can be deformed according to the shape of the object being packaged, so that the elastic airbag can be closely attached to the outer surface of the object, thereby playing a role of anti-collision buffer protection for the object, and at the same time, the object tightly wrapped in the elastic airbag can be fixed and stable Good; and because the sealed box is a non-oxidative dry vacuum environment, the objects in it are kept in a constant dry environment and will not change due to changes in the surrounding humidity environment, which overcomes the poor stability of the anti-collision buffer protection in the prior art , The drying effect is due to the disadvantages of environmental changes.

Because the utility model has the advantages of good stability of anti-collision buffer protection and drying effect, the utility model can be used for various packaging containers that require anaerobic or/and dry or/and buffer packaging such as camera lenses, rings, watches, etc.

Detailed ways

Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.

Embodiment one

As shown in Fig. 1, Fig. 2 and Fig. 3, a vacuum packaging device includes a vacuum-pumpable sealed box 1, the sealed box 1 includes a connected upper cover 2 and a lower box 3, and the lower box 3 is provided with two 4 elastic airbags. An air extraction hole 5 is arranged on the upper cover 2, and a sealing check valve 6 is arranged in the air extraction hole 5. The air hole 5 is an interface for vacuuming the inside of the sealed box 1 using a vacuum pump. The sealing one-way valve 6 is opened during the vacuuming process, that is: the sealing one-way valve 6 opens the air flow passage between the air pumping hole 5 and the inside of the sealing box 1; The direction valve 6 is just closed, that is: the sealing check valve 6 closes and seals the air flow channel between the air extraction hole 5 and the sealing box 1 . In this embodiment, a knob air seal switch 10 is also provided in the air pumping hole 5. Before vacuuming, the knob air seal switch 10 is manually opened. After vacuuming, turn off the vacuum pump, and then close the sealing check valve 6. In order to achieve absolute sealing, the knob air seal switch 10 can be manually tightened, so that the knob air seal switch 10 presses the sealing check valve 6 to seal The one-way valve 6 is in an unopenable state, thereby playing a double sealing effect. The upper cover 2 is provided with an air release valve. The air release valve in this embodiment includes a pull button 9 and a rubber air plug 7 linked with the pull button 9. When the airtight box 1 is in a vacuum state, the airtight box 1 needs to be opened. , pull the button 9, the button 9 drives the rubber air plug 7 to open the air release valve, so that the inside of the sealed box 1 is ventilated with the outside of the box, and then the air pressure inside the sealed box 1 is the same as the air pressure outside the box, and then it can be opened Cover 2. An elastic seal 8 is arranged between the upper cover 2 and the lower box 3. In this embodiment, a circle of elastic seals 8 is arranged on the inner periphery of the cover of the upper cover 2. When the upper cover 2 is fastened on the lower box 3, the upper cover 2 and the lower box 3 The upper and lower buckling of the lower box 3 squeezes the elastic seal 8 between the contact surfaces of the two, so that the tightness of the buckling between the upper cover 2 and the lower box 3 is better.

As shown in Figure 1, Figure 2 and Figure 3, when the vacuum packaging device of this embodiment is in use, the object W to be packaged is first put into the lower box 2, and the object W is placed in the middle of the elastic air bag 4 , and then fasten the upper cover 2 on the lower box 3, then use the suction pipe of the vacuum pump to align the suction hole 5, turn on the vacuum pump, and then open the sealing check valve 6, that is: the sealing check valve 6 connects the suction hole 5 to the The air passage between the sealed boxes 1 is opened, and then the sealed box 1 is negative pressure, because the air pressure in the elastic air bag 4 is greater than the air pressure in the sealed box 1, the elastic air bag 4 will expand and bulge, and then the The object W is wrapped in the middle of the elastic airbag 4, and because the elastic airbag 4 itself is elastic, it can be deformed according to the shape of the wrapped object W, so that the elastic airbag 4 can be closely attached to the outer surface of the object W, thus playing a role in protecting the object W. The anti-collision cushioning protection effect, and the fixed stability of the object W tightly wrapped in the elastic airbag 4 is good at the same time; and because the inside of the sealed box 1 is a non-oxidative dry vacuum environment, the object W in it is kept in a constant dry environment. It can change due to the change of the surrounding humidity environment, and overcomes the disadvantages of poor stability of the anti-collision buffer protection and the drying effect due to the change of the environment in the prior art. When the sealing box 1 needs to be opened, the deflation valve can be opened to make the air pressure in the sealing box 1 the same as the air pressure outside the box, and then the upper cover 2 can be opened, and the elastic air bag 4 is also due to the air pressure of the external environment and the air pressure in the elastic air bag 4. When the air pressure equalizes and the original size is restored, the object W can be taken out.

The above embodiment is only a preferred example.
