[0004] However, the above-mentioned vacuum packaging and sealing machine also has the following disadvantages 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 In the case that the cavity is completely sealed without air leakage, but in actual use, the cavity is often not completely sealed by the cover plate, and there will always be some gaps that allow air to enter the cavity. After a long period of time, the cavity cannot reach the predetermined vacuum degree. 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
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] Depend on Figure 1 to Figure 7 As shown, the vacuum packaging sealing machine of the present invention includes a base 1, a cover plate 2, a vacuum pump 3 and a sealing mechanism, and the base 1 is provided with a cavity 4 for placing a packaging bag with a product, the cavity 4 The bottom of the vacuum pump 3 is connected to the concave cavity 4 through a pipeline, and the cover plate 2 is used to cover the base 1 to seal the cavity 4. A retractable first airbag 5 is arranged on the top, a third conductive element 501 is fixed on the first airbag 5, and a first air hole 6 for communicating the first airbag 5 with the atmosphere is arranged on the cover plate 2.
[0032] A first groove 7 is arranged in the cavity 4, a first conductive element 8 and a second conductive element 9 are arranged in the first groove 7, the upper en...

The invention discloses a vacuum package sealing machine. Only when a vacuum degree achieved by a vacuum pump working in a concave cavity reaches a preset value, an air cylinder can act to conduct hot-pressing and sealing on the opening end of a packaging bag, and therefore it can be ensured that the vacuum degree in a vacuum bag is qualified; a second air bag is further arranged, the second air bag can extend in the vacuumizing process, and after extending, the second air bag is in contact with the packaging bag and extrudes the packaging bag; and in this way, the second air bag can extrude air in the packaging bag out, so that the air is not liable to remain in the packaging bag, and it is better ensured that the vacuum degree in the packaging bag is qualified.
Description
technical field [0001] The invention relates to a vacuum packaging sealing machine. Background technique [0002] The vacuum packaging and sealing machine 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 low oxygen, so that microorganisms have no living conditions, so as to achieve the purpose of fresh food and no rot. [0003] Present vacuum packaging and sealing machines generally include a base, a cover plate, a vacuum pump and a sealing mechanism. The cavity is sealed. The suction port of the vacuum pump is connected to the cavity through the pipeline. The sealing mechanism is set in the cavity. The vacuum pump pumps out the air in the concave cavity, and after the vacuum pump works for a period of time, the sealing mechanism seals the opening end of the packaging bag to complete the vacuum packaging of the product. [0004] However, the above-mention...
