The unwinding mechanism 7 and the rewinding mechanism 8 arranged on the box body 1 are used for conveying the sealing film 9, and the plastic sealing mechanism 5 arranged inside the box body 1 can heat-seal the sealing film 9 on the packaging box to ensure that the packaging box will not leak out after heat sealing.

[0026] Example 2

[0027] Based on Example 1, an observation window 10 is provided on the side of the box body 1, and transparent glass is embedded in the observation window 10. Through the observation window 10, the user can clearly observe the position of the sealing film 9 inside the box body 1 to prevent the sealing film 9 from not completely covering the packaging box during packaging.

[0028] Example 3

[0029] Based on Example 2, a movable groove 201 is provided on the inner wall of the box body 1. Both ends of the movable groove 201 are closed. A connecting block 202 is provided in the movable groove 201. The connecting block 202 is fixedly connected to the side of the movable plate 2. The movable plate 2 can only move within the range of the movable groove 201, which facilitates the entry and exit of the box body 1 for taking and placing packaging boxes.

[0030] Example 4

[0031] On the basis of embodiment 3, a handle 203 is fixedly connected to the movable plate 2 to facilitate the user to apply force to move the movable plate 2.

[0032] Example 5

[0033] On the basis of embodiment 4, a plurality of guide rollers 11 are fixedly mounted on the box body 1. This can prevent the sealing film 9 from directly contacting the box body 1, so as to avoid damage to the sealing film 9 and failure to seal and pack the packaging box.

[0034] Example 6

[0035] On the basis of Example 5, the plastic sealing mechanism 5 includes an external pressure box 501 and an internal pressure box 502. The bottom surfaces of the external pressure box 501 and the internal pressure box 502 are both provided with openings. A cutting blade 503 is fixedly installed at the bottom end of the external pressure box 501. The internal pressure box 502 is fixedly installed inside the external pressure box 501, and a heat sealing plate 504 is fixedly installed at the bottom end of the internal pressure box 502. Because the sealing film 9 is usually made of plastic material, it has flexibility and can be stretched to a certain extent. During the process of the plastic sealing mechanism 5 pressing down to perform heat sealing, the cutting blade 503 does not immediately cut the sealing film 9. Instead, after the heat sealing plate 504 heat-melts the sealing film 9 to the bowl edge of the packaging box, the sealing film 9 can no longer be stretched. Only then can the cutting blade 503 cut the sealing film 9 on the periphery of the packaging box to complete the packaging work.

[0036] Example 7

[0037] On the basis of Example 6, the unwinding mechanism 7 includes an unwinding shaft 701, and fixed plates 702 are provided on both sides of the unwinding shaft 701. The bottom of the fixed plate 702 is fixedly connected to the top surface of the box body 1, and a conductive fixing hole 703 is provided on the side of the fixed plate 702. The two ends of the unwinding shaft 701 respectively cooperate with the fixing holes 703 on the two fixing plates 702, and the hole walls of the fixing holes 703 are connected to the top surface of the fixing plates 702. Two fixing grooves 704 are symmetrically provided on the hole walls on both sides of the fixing hole 703 near the top surface of the fixing plate 702, and two limiting rods 705 are symmetrically provided between the two fixing grooves 704. After one end of the limiting rod 705 is inserted into the fixing groove 704, it is hinged to the top closed end of the fixing groove 704, and a torsion spring is provided on the hinged end of the limiting rod 705. The unwinding shaft 701 is used to place the rolled-up, unused sealing film 9. When installing the sealing film 9, the two ends of the unwinding shaft 701 can be directly placed from above the fixing plate 702, so that the two ends of the unwinding shaft 701 cooperate with the fixing holes 703 on the fixing plate 702. The limiting rod 705 on the fixing plate 702 ensures that the unwinding shaft 701 can only move down into the fixing hole 703 and cannot rise up and away from the fixing plate 702, so that the sealing film 9 can be stably placed on the top of the box body 1.

[0038] Example 8

[0039] On the basis of Example 7, the winding mechanism 8 includes a winding shaft 801, and a first mounting plate 802 and a second mounting plate 803 are fixedly mounted in parallel on the outer wall of the box body 1, and a conductive matching hole 804 is provided on the side of the first mounting plate 802 close to the second mounting plate 803, and the hole wall of the matching hole 804 is connected to the top surface of the first mounting plate 802, and one end of the winding shaft 801 passes through the matching hole 804 and contacts the side of the second mounting plate 803, and a limiting hole 806 is provided on the end face where the winding shaft 801 contacts the second mounting plate 803, and a fixing bolt 805 is provided on the side of the second mounting plate 803 away from the winding shaft 801, and the screw of the fixing bolt 805 passes through the second mounting plate 803 and is inserted into the limiting hole 806, and the fixing bolt 805 is threadedly connected to the winding shaft 801 and rotatably connected to the second mounting plate 803. The reel 801 is used to reel in the cut sealing film 9. The reel 801 is mounted on the box body 1 via a fixing bolt 805, but can rotate and reel normally. When the reel 801 needs to be removed to process the waste sealing film 9, it is only necessary to loosen the connection between the fixing bolt 805 and the reel 801.

[0040] Example 9

[0041] On the basis of Example 8, a torsion bar 807 is fixedly mounted on the end of the reel 801 away from the second mounting plate 803, so as to facilitate the user to apply force to the reel 801 to rotate.

[0042] Working principle: When in use, first power on the packaging device to start, so that the hydraulic cylinder 6 and the heat-sealing plate 504 are powered and can work, pull the movable plate 2 out from the inside of the box body 1, and place the packaging box containing food on the placement ring 3. The bottom of the packaging box contacts the movable plate 2, and the bowl edge of the packaging box contacts the top surface of the placement ring 3 to ensure that the packaging box will not be deformed by force when the plastic sealing mechanism 5 moves down to heat-seal the packaging box. Then push the movable plate 2 back into the inside of the box body 1, apply force to rotate the reel 801, and unwind. The shaft 701 rotates simultaneously under the pull of the sealing film 9, so that the sealing film 9 can be conveyed, ensuring that the uncut part of the sealing film 9 covers the packaging box, and then the hydraulic cylinder 6 is controlled to move the plastic sealing mechanism 5 downward, and the sealing film 9 is heat-sealed to the packaging box by the heat-sealing plate 504 on the inner pressure box 502, and the cutting blade 503 on the outer pressure box 501 cuts the sealing film 9 to complete the packaging of the packaging box, and then the movable plate 2 is pulled out from the inside of the box body 1, and the packaged packaging box is taken out from the placement ring 3.
