[0038] The vacuum device 5 includes four electric telescopic rods A51 installed at the four corners of the top of the upper crossbeam frame 1, and the movable ends of the electric telescopic rods A51 are located below the upper crossbeam frame 1, and a bin cover 52 is fixedly connected between the movable ends of the four electric telescopic rods A51. A vacuum pump 56 is installed on the top of the bin cover 52, and the air intake port of the vacuum pump 56 is connected to the air outlet on the top of the bin cover 52;

[0039] The packaging and smoothing device 4 includes a vibration body 41 installed at the bottom of the lower vacuum bin 2, an equipment bin 42 is installed on the vibration body 41, a storage bin 43 is welded at the open top of the equipment bin 42, a loading body 46 is installed inside the equipment bin 42, and the movable end of the loading body 46 is located inside the storage bin 43, a limited material body A44 is installed on the front and rear sides of the storage bin 43, and a limited material body B45 is arranged at the bottom of the inner wall of the storage bin 43.

[0040] The packaging bag is positioned between the material-carrying body 46, the material-limiting body B45 and the two material-limiting bodies A44, and the packaging bag is limited from five sides to ensure that the packaging bag is placed in a vertically upward position to avoid the packaging bag from tilting and leaking the miscellaneous grains inside when the packaging bag is vacuumed.

[0041] Sealing strips 3 are bonded to the four sides of the top of the lower vacuum chamber 2. The sealing strips 3 are used to ensure that there is no gap between the lower vacuum chamber 2 and the chamber cover 52, thereby ensuring the sealing of the cavity.

[0042] Rod racks are welded to the front and rear sides of the inner wall of the bin cover 52, and electric telescopic rods B53 are installed on both sides of the top of the rod rack. A mounting connecting plate 55 is fixedly connected between the movable ends of the two electric telescopic rods B53, and an electric heating strip 54 is fixedly installed on the side of the mounting connecting plate 55 away from the electric telescopic rod B53.

[0043] During use, the packaging bag containing cereals is placed in the storage cavity of the packaging smoothing device 4, and the cereals are placed on the movable end of the material-carrying body 46.

After the vacuum is evacuated, the electric heating strip 54 is turned on for heating to seal the packaging bag.

[0046] Example 2

[0047] Reference Figure 1-7 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0048] The loading body 46 includes four electric telescopic rods C461, and the four electric telescopic rods C461 are respectively installed at the four corners of the inner wall of the equipment warehouse 42. The movable ends of the electric telescopic rods C461 are fixedly connected to the vertical columns, and the movable ends of the vertical columns are located inside the storage warehouse 43. A lifting plate 462 is welded between the tops of the four vertical columns. The extension and retraction of the electric telescopic rods C461 can adjust the height of the lifting plate 462. The height of the lifting plate 462 is adjusted according to the different depths of the packaging bags to ensure that the head end of the packaging table is exposed above the storage warehouse 43.

[0049] The material limiting body B45 includes a dovetail guide bar 451 installed at the bottom of the inner wall of the storage bin 43, and a dovetail groove sliding on the dovetail guide bar 451 is opened at the bottom of the vertical bar 453.

[0050] A threaded hole is provided on one side of the vertical bar 453, and a bidirectional screw rod 452 is threadedly installed on the vertical bar 453 through the threaded hole. The bidirectional screw rod 452 is rotatably installed on the storage bin 43 through a bearing. A servo motor is also installed inside the storage bin 43, and the servo motor drives the bidirectional screw rod 452 to rotate.

[0051] The material limiting body A44 includes two electric telescopic rods D441 installed on the storage bin 43, and the movable ends of the electric telescopic rods D441 are located inside the storage bin 43. A U-shaped frame 442 is fixedly connected between the movable ends of the two electric telescopic rods D441. A limiting roller 443 is rotatably installed in the inner cavity of the U-shaped frame 442 through a bearing. When the packaging bag contacts the limiting roller 443, rolling contact between them is avoided to avoid damage to the packaging table.

[0052] The height of the lifting plate 462, the distance between the vertical bars 453 on both sides, and the distance between the front and rear limiting rollers 443 can be adaptively adjusted according to the size of the packaging bag.

[0054] After the packaging bag is limited, the ultrasonic generator 411 puts the equipment bin 42 into a high-frequency vibration state through the transducer 413, and the vibration will be transmitted to the inside of the storage bin 43, so that the packaging bag is in a vibrating state. The vibration of the packaging bag will compact the grains inside the packaging bag, which is more conducive to vacuuming the packaging bag.

[0055] During use, the extension and retraction of the electric telescopic rod C461 can adjust the height of the lifting plate 462, and the servo motor drives the bidirectional screw rod 452 to rotate. Under the threaded transmission action of the bidirectional screw rod 452 and the vertical bar 453, the spacing between the vertical bars 453 on both sides is adjusted.

Therefore, the height of the lifting plate 462, the spacing between the vertical bars 453 on both sides, and the spacing between the front and rear limiting rollers 443 can be adaptively adjusted according to the size of the packaging bag.

[0056] The remaining structures are the same as those of Example 1.
