An air box 6 is provided on the top of the box body 1, and the surface of the air box 6 An air pump 61 is movably connected, and one end of the air pump 61 is movably connected to a connecting hose 62. A hollow block 7 is provided on the inner side of the box body 1. A rectangular block 8 is fixedly installed on the bottom of the hollow block 7. The rectangular block 8 is located vertically above the plastic sealing film 53. A feed port 301 is provided on the outer wall of the circular frame 3. A guide groove 302 is provided on the top of the circular frame 3. The guide groove 302 is arc-shaped. A discharge port 303 is provided at the bottom of the guide groove 302. A guide plate 33 is fixedly installed on the inner side of the discharge port 303. An isolation block 32 is provided on the top of the circular frame 3. The isolation block 32 is located on the inner side of the guide groove 302. A groove 321 is provided inside the isolation block 32. The size of the push rod 41 matches the size of the groove 321. A servo motor 42 is movably connected to the bottom of the movable frame 4. The servo motor 42 is fixedly installed inside the limit block 31.

[0024] In this embodiment, by dropping the packaging box onto the top of the conveying mechanism 2, the conveying mechanism 2 moves to transport the packaging box to the right to the inside of the guide groove 302 of the circular frame 3, and the baffle 21 can limit the packaging box. When the packaging box moves to the inside of the guide groove 302, the servo motor 42 drives the movable frame 4 and the push rod 41 to rotate, and the push rod 41 has the effect of separating and isolating the packaging box. The push rod 41 rotates intermittently when pushing the packaging box to the bottom of the rectangular block 8.

[0025] Example 2

[0026] like Figure 1-Figure 4As shown in the figure, a first cylinder 71 is fixedly installed at the top of the outer wall of the box body 1. A first telescopic rod 72 is movably connected to the bottom of the first cylinder 71. Fixed blocks 73 are fixedly installed on both sides of the hollow block 7. The bottom of the first telescopic rod 72 is fixedly connected to the top of the fixed block 73. The bottom end of the connecting hose 62 is fixedly installed inside the hollow block 7.

The second cylinder 9 controls the heating block 92 to move upward into the rectangular block 8. When the bottom of the rectangular block 8 contacts the top of the packaging box, the air pump 61 adds a fresh-keeping gas into the rectangular block 8 through the connecting hose 62 and the hollow block 7. The fresh-keeping gas flows into the packaging box through the ventilation opening 801. Subsequently, the second cylinder 9 drives the heating block 92 to move back, causing the plastic sealing film 53 to contact the top of the packaging box. After the plastic sealing film 53 cools down, the packaging of the packaging box is completed. The push rod 41 drives the packaged packaging box to move to the discharge port 303 for collection. At the same time, the push rod 41 continuously performs the packaging operation on the subsequent packaging boxes, realizing the continuity of the packaging of the packaging boxes.

[0028] The working principle of this embodiment: Place the packaging box on the top of the conveying mechanism 2. The conveying mechanism 2 moves to convey the packaging box to the inside of the guiding groove 302 of the circular frame 3 to the right. The servo motor 42 drives the movable frame 4 and the push rod 41 to rotate. The push rod 41 intermittently rotates while pushing the packaging box towards the bottom of the rectangular block 8. The first cylinder 71 drives the hollow block 7 to move downward through the first telescopic rod 72, causing the rectangular block 8 to contact the top of the packaging box. During the downward movement of the rectangular block 8, the heating block 92 heats up to thermally melt the plastic sealing film 53, causing it to adhere to the bottom of the heating block 92. The second cylinder 9 controls the heating block 92 to move upward into the rectangular block 8. When the bottom of the rectangular block 8 contacts the top of the packaging box, the air pump 61 adds a fresh-keeping gas into the rectangular block 8. The fresh-keeping gas flows into the packaging box through the ventilation opening 801. Subsequently, the second cylinder 9 drives the heating block 92 to move back, causing the plastic sealing film 53 to contact the top of the packaging box. After the plastic sealing film 53 cools down, the packaging of the packaging box is completed.
