[0033] The driving mechanism 6 is installed on one side of the sealing mechanism 1 and is connected to the space adjustment mechanism 3 and the loosening mechanism 5 to drive the operation of both; The driving mechanism 6 includes a motor plate 61 fixed to one side of the feeding box 11. At the bottom of the motor plate 61, a motor 62 is fixed. One end of the output shaft of the motor 62 is fixed with a first gear 63. One side of the first gear 63 meshes with the one-way first gear 38, and the other side of the first gear 63 meshes with the one-way second gear 55.

[0034] A controller 7 is fixed to one side of the feeding box 11. The controller 7 is electrically connected to the vacuum pump 21, the motor 62, the heating top plate 14, the heating bottom plate 12, and the electric telescopic rod 58.

[0035] Working principle: Place the bag containing the chemical raw materials inside the feeding box 11, and position the bag mouth between the heating top plate 14 and the heating bottom plate 12, and then start the vacuum extraction program through the controller 7; The starting motor 62 drives the first gear 63 to rotate forward. The forward rotation of the first gear 63 meets the rotation direction requirement for the one-way first gear 38 to drive the reciprocating screw rod 31 to rotate. The rotation of the reciprocating screw rod 31 drives the first moving plate 33 to move downward. After the support of the first moving plate 33 is removed, the rear frame 34, the flexible heat insulation material 39, the granular material, the push plate 43, the first cylinder 42, the cross 41, the first spring 46, the sleeve plate 45, the rack 26 and the pressing block 44 move downward. The drooping flexible heat insulation material 39 and the granular material fill the gaps between the bags when moving downward. After the bottom of the frame 34 contacts the top of the feeding box 11, the top of the feeding box 11 is sealed. After the frame 34 stops moving, the first moving plate 33 continues to move downward to compress the first spring 46. The first spring 46 presses on the sleeve plate 45, causing the sleeve plate 45 to drive the frame 34 to closely fit with the top of the feeding box 11. When the first moving plate 33 compresses the first spring 46, the pressing block 44 moving downward presses the piston rod of the second cylinder 48, compressing the second spring 49. The piston rod pushes the gas in the second cylinder 48 into the interior of the first cylinder 42, pushing the piston rod inside the first cylinder 42 downward. The piston rod pushes the push plate 43 to press the granular material below. The granular material deforms the flexible heat insulation material 39, filling the gaps between the bags. The air in the sealed feeding box 11 is discharged through the three-way pipe 22 and the elbow pipe 23. When exhausting, the rack 26 moves downward and contacts the second gear 25, gradually closing the butterfly valve 24. When the push plate 43 moves downward to the specified position, all the gas in the first cylinder 42 is filled into the interior of the second cylinder 48. The first moving plate 33 also moves to the thread end position of the reciprocating screw rod 31. When continuing to rotate, the first moving plate 33 moves upward, and the butterfly valve 24 is completely closed. When the frame 34 moves downward, the bottom edge will contact the top of the electric telescopic rod 58, pushing the electric telescopic rod 58 to rotate around the connection point with the second moving plate 56, making one end of the electric telescopic rod 58 face downward. When rotating, it compresses the third spring 59 to make it bend and store energy; When the frame 34 moves downward, the push rod 310 contacts the top of the heating top plate 14 and pushes it to compress the spring telescopic rod 13, closing the heating top plate 14 and the heating bottom plate 12 to clamp the bag mouth; Start the vacuum pump 21 to extract the excess gas inside the feeding box 11 through the three-way pipe 22. When extracting, the air inside the bag is discharged through the bag mouth, creating a vacuum environment inside. Then the controller 7 starts the heating top plate 14 and the heating bottom plate 12 to heat the bag mouth to seal it; Continue to start the motor 62 to drive the first gear 63 to rotate forward, so that the first moving plate 33 that has moved to the end of the wire moves upward. When it moves to the top of the sliding groove 35, the first spring 46 resets. When resetting, the rack 26 moves upward to open the butterfly valve 24. The first moving plate 33 drives the frame 34 to move upward, separating it from the top of the feeding box 11. Then, the second spring 49 pushes the piston rod of the second cylinder 48 to reset, sucking the gas in the first cylinder 42. The first cylinder 42 drives the piston rod inside to pull the push plate 43 upward. The spring telescopic rod 13 pushes the heating top plate 14 to reset. At the same time, the controller 7 broadcasts the voice of safe material taking to prevent the hand from being scalded by the heating top plate 14 and the heating bottom plate 12 during material taking. During the process of the frame 34 moving to the top, the electric telescopic rod 58 is released from extrusion. The electric telescopic rod 58 is pushed to the horizontal by the third spring 59 and then extends to the specified length. Then, start the motor 62 to drive the first gear 63 to reverse. The reverse rotation of the first gear 63 meets the rotation direction for the second one-way gear 55 to drive the second reciprocating screw 52 to rotate, so that the second moving plate 56 drives the electric telescopic rod 58 to move up and down reciprocally. The up and down movement of the electric telescopic rod 58 pushes the flexible heat-resistant material 39 above, making the compressed granular material become soft again, ensuring the fluidity during the next void filling. At the same time, manually take out the evacuated bag to complete the vacuum packaging.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
