Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides an embodiment: a vacuum sealing machine with an adaptive heat sealing pressure adjustment mechanism, including a machine base 2, a movable seat 6 at the top of the machine base 2, and a vacuum chamber 26 inside the bottom of the movable seat 6. Connecting seats 11 are fixed on both sides inside the vacuum chamber 26, and an upper heating plate 16 is provided at the bottom of the connecting seat 11. Slide rods 20 are vertically fixed at both ends of the top of the upper heating plate 16, and compression springs 21 are provided on the outside of the slide rods 20. The top of the slide rods 20 passes through the inside of the top of the connecting seat 11 and is fixed with a limit plate 19. Lower heating plates 15 are fixed on both sides of the front end of the top of the machine base 2, and a top seat 8 is provided at the top of the movable seat 6.

[0023] The connecting seat 11 and the upper heating plate 16 are symmetrically arranged about the vertical center line of the movable seat 6. The top end of the compression spring 21 is fixedly connected to the bottom end of the connecting seat 11, and the bottom end of the compression spring 21 is fixedly connected to the top end of the upper heating plate 16.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, after the opening of the packaging bag is placed at the top of the lower heating plate 15, the movable seat 6 can be driven to move down by the control cylinder 10. At the same time, the upper heating plate 16 can be driven to move down and press against the top of the bag opening. During the process of the movable seat 6 moving down and fitting with the top of the machine base 2 to close, after the upper heating plate 16 presses against the bag opening, the compression spring 21 on the outside of the slide rod 20 can adapt to some packaging bag openings of different thicknesses and maintain tight heat sealing.

[0025] Fixed seats 3 are fixed on both sides of the top of the machine base 2, and mounting seats 4 are provided on the top of the fixed seats 3. Guide rods 5 are vertically fixed at both ends of the top of the mounting seats 4. Sliding sleeves 7 are fixed at both ends of both sides of the movable seat 6. The top of the guide rods 5 passes through the interior of the sliding sleeves 7 and is fixedly connected to the bottom of the top seat 8. A slider 14 is fixed at the bottom of the mounting seat 4. A sliding groove 13 is provided inside the top of the fixed seat 3. Plugs 22 are fixed at both ends of the fixed seat 3. The two ends of the sliding groove 13 pass through the interior of both ends of the fixed seat 3. The mounting seat 4 is slidably connected inside the sliding groove 13.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, by pushing the movable seat 6 backward to the rear end of the top of the machine base 2 using the slider 14 at the bottom of the mounting seat 4, the front end area of ​​the top of the machine base 2 is exposed, which facilitates convenient loading and unloading operations when sealing the packaging bag.

[0027] Fixed feet 1 are fixed at both ends of the bottom of both sides of the machine base 2, and threaded sleeves 24 are fixed inside the fixed feet 1. A screw rod 23 is threaded inside the threaded sleeve 24, and a handle 25 is fixed at the top of the screw rod 23. A stop plate 18 is provided at the bottom of the fixed feet 1. The threaded sleeve 24 passes through the inside of the fixed feet 1, and the bottom of the screw rod 23 passes through the inside of the threaded sleeve 24 and is movably connected to the top of the stop plate 18.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, after the sealing machine is moved to the working position using the four sets of moving wheels 17 at the bottom, the handle 25 can be turned on the fixed feet 1 on both sides of the machine base 2 to drive the lead screw 23 to rotate. The lead screw 23 rotates inside the threaded sleeve 24 and at the same time drives the abutment plate 18 to move down and abut against the ground. The four sets of abutment plates 18 can be used to assist in positioning the bottom of the machine base 2.

[0029] Cylinders 10 are installed and fixed on both sides of the top of the top seat 8, and the output end of the bottom of the cylinder 10 passes through the interior of the top seat 8 and is installed and fixed between it and the top of the movable seat 6. A vacuum pump 9 is installed inside the movable seat 6. Moving wheels 17 are installed and fixed at the four corners of the bottom of the machine base 2, and a sealing gasket 12 is fixed at the bottom of the movable seat 6.

[0030] Working Principle: When using the sealing machine, the movable seat 6 is pushed backward by the slider 14 at the bottom of the mounting base 4 to the rear end of the top of the machine base 2, exposing the front end area of ​​the top of the machine base 2. This allows for convenient loading and unloading operations during the sealing of packaging bags. It is a sliding component. After the packaging bag opening is placed on top of the lower heating plate 15, the movable seat 6 is driven downward by the control cylinder 10, simultaneously driving the upper heating plate 16 downward to press against the top of the bag opening. During the sealing process, as the movable seat 6 moves downward and adheres to the top of the machine base 2, the upper heating plate 16 presses against the bag opening. The compression spring 21 on the outside of the slide rod 20 can adapt to packaging bag openings of different thicknesses, maintaining a tight heat-sealed seal. During vacuum sealing, after the movable seat 6 moves downward and adheres to the top of the machine base 2, the vacuum pump 9 is activated to evacuate the vacuum chamber 26. Finally, the lower heating plate 15 and the upper heating plate 16 heat and seal the bag. Furthermore, after the sealing machine is moved to the working position using the four sets of moving wheels 17 at the bottom, the handle 25 can be turned on the fixed feet 1 on both sides of the machine base 2 to drive the lead screw 23 to rotate. The lead screw 23 rotates inside the threaded sleeve 24 and at the same time drives the abutment plate 18 to move down and abut against the ground. The four sets of abutment plates 18 can be used to assist in moving and positioning the bottom of the machine base 2.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
