Problems solved by technology

[0004] However, the above-mentioned vacuum packaging device also has the following disadvantages when in use: after the vacuum pump works for a period of time (the length of time is set in advance), it is considered that the vacuum degree in the concave cavity is qualified, and then the product is sealed, but this is only applicable to The concave cavity is completely sealed without air leakage, but in actual use, the concave cavity is often not completely sealed by the cover plate, and there will always be some gaps that allow air to enter the concave cavity. After the length is exceeded, the predetermined vacuum degree cannot be reached in the concave cavity. At this time, sealing the packaging bag will make the vacuum degree in the packaging bag unqualified, so that the residual air in the packaging bag will easily cause the food in the packaging bag to rot.

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Depend on Figure 1 to Figure 7 As shown, the vacuum packaging device of the present invention includes a base 1, a cover plate 2, a vacuum pump 3 and a sealing mechanism. The base 1 is provided with a cavity 4 for placing a packaging bag containing a product. The bottom is horizontal so that the packaging bag can be placed horizontally. The cover plate 2 is used to cover the base 1 to seal the cavity 4. The suction port of the vacuum pump 3 communicates with the cavity 4 through a pipeline. The cover plate 2 A retractable airbag 5 is provided, on which a third conductive element 501 is fixed, and an air hole 6 for communicating the airbag 5 with the atmosphere is provided on the cover plate 2 .

[0030] A first groove 7 is arranged in the cavity 4, a first conductive element 8 and a second conductive element 9 are arranged in...

Abstract

The invention discloses a vacuum packaging device. After a packaging bag is placed in a cavity, only when a vacuum pump works to enable the vacuum degree in the cavity to reach a preset value, an aircylinder can act to conduct hot press seal on the open end of the packaging bag. In this way, the vacuum packaging device can guarantee that the vacuum degree in the vacuum packaging bag is qualified.

Description

technical field [0001] The invention relates to a vacuum packaging device. Background technique [0002] The vacuum packaging device can extract all the air in the packaging container and seal it to maintain a high degree of decompression in the bag. The scarcity of air is equivalent to the effect of hypoxia, so that microorganisms have no living conditions, so as to achieve the purpose of fresh food and no rot. [0003] The current vacuum packaging device generally includes a base, a cover plate, a vacuum pump and a sealing mechanism. The base is provided with a cavity for placing the packaging bag containing the product, and the cover plate is used to cover the base to close the cavity. Sealing, the suction port of the vacuum pump is connected with the concave cavity through the pipeline, and the sealing mechanism is set in the concave cavity. The air in the concave cavity is drawn out, and after the vacuum pump works for a period of time, the sealing mechanism seals the ...
