[0025] In use, the L-shaped mounting base 10 is used to place the first clamping plate 18 and other related clamping components.

[0026] A first clamping plate 18 is provided on the inner wall of one side of the L-shaped component holder 10, and a nut seat 19 is provided on the inner wall of the other side of the L-shaped component holder 10.

[0027] In use, the first clamping plate 18 is set so that it can work with the second clamping plate 21 to clamp and limit the packaging bag from the side;

[0028] The nut seat 19 has a threaded rod 20 installed on its internal threads, and both ends of the threaded rod 20 extend to the outside of the nut seat 19.

The second clamping plate 21, in conjunction with the first clamping plate 18, clamps and limits the packaging bag from both sides. Then, several electric telescopic rods 7 drive the sealing table 8 to move up and down, causing the sealing table 8 to lift and lower the packaging bag placed at its top. This aligns the designated area of ​​the packaging bag opening with the heat sealing head 17, allowing the heat sealing head 17 to seal the packaging bag from the designated area. This process can handle packaging bags of different heights. The bag is sealed. Finally, the electric push rod 14 drives the strip plate 12 to move horizontally via the connecting frame 15. This causes the strip plate 12 to slide along the top of the limit rail 6, allowing the strip plate 12 to smoothly move the heat sealing head 17 horizontally and bring the two heat sealing heads 17 closer together. When the heat sealing head 17 is in contact with the bag opening area, the bag opening can be heat-sealed. Specifically, when the heat sealing head 17 is heated and it contacts the bag opening, the sealing area of ​​the bag reaches a viscous state. Pressure is then applied to make the bag openings stick together in a molten state. After cooling, a strong seal is formed, thus sealing the bag and completing the use of the sealing device.
