The working principle is as follows:
in the using process of the invention, a packaging bag is placed in the containing shell 130, the edge of the bag mouth of the packaging bag is placed below the first pressure wheel 144 and the second pressure wheel 146, the first pressure wheel 144 and the second pressure wheel 146 compress the bag mouth of the packaging bag, when the air pump 30 pumps the packaging bag, when air passes through the first connecting shell 320, the air pushes the first dial wheel 340 to rotate, so as to drive the first connecting shaft 350 to rotate, so as to drive the first centrifugal rod 360 to rotate and extend, the end part of the first centrifugal rod 360 abuts against the guide plate 560, so that the guide plate 560 moves upwards along the connecting rod 510, when the air in the packaging bag is exhausted, the first dial wheel 340 stops rotating, the first centrifugal rod 360 stops rotating and contracts, the elastic force of the first spring pushes the guide plate 560 to move downwards along the connecting rod 510, so that the first sensor 370 detects the guide plate 560, so as to close the cover plate 110; when the packaging bag needs to be inflated, when the air suction of the packaging bag is completed, the electromagnet 540 is electrified, the electromagnet 540 attracts the external step at the end part of the guide post 550, the guide plate 560 moves towards the direction close to the third connecting shell 413 along the guiding direction of the guide post 550, the push plate 570 and the opening and closing mechanism 420 work, so that the third connecting shell 413 is in a circulating state, the end part of the guide plate 560 is flush with the third sensor 390, and then the third sensor 390 sends out a sensing signal and controls the air blowing pump 40 to work, so that the packaging bag is blown. When the air pressure in the communication pipe five 431 is higher, the air pushes the connection column 435 to move along the communication pipe five 431, so as to push the push block 434 to abut against the outer annular surface of the first rotating shaft 416a, then the first rotating shaft 416a moves towards the direction close to the second thumb wheel 415, the first rotating shaft 436 is separated from the second rotating shaft 416b, so that the transmission between the first rotating shaft 416a and the second rotating shaft 416b is interrupted, then the second centrifugal rod 417 contracts, the guide plate 560 moves downwards along the connection rod 510, then the second sensor 380 detects the guide plate 560, so that the cover plate 110 is closed, and the electric heating block 120 at the bottom of the cover plate 110 seals the packaging bag.
It should be understood that the above-described embodiments are merely preferred embodiments of the invention and the technical principles applied thereto. It will be understood by those skilled in the art that various modifications, equivalents, changes, and the like can be made to the present invention. However, such variations are within the scope of the invention as long as they do not depart from the spirit of the invention. In addition, certain terms used in the specification and claims of the present application are not limiting, but are used merely for convenience of description.
