Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, an accounting voucher vacuum sealing machine is disclosed, comprising an external vacuum packaging machine body 1. The front end of the external vacuum packaging machine body 1 is provided with a sealing strip 3 and an air extraction nozzle 4. A workbench 2 is fixedly connected to the outer side of the front end of the external vacuum packaging machine body 1. Fixing frames 5 are fixedly connected to both sides of the air extraction nozzle 4 at the front end of the external vacuum packaging machine body 1. A first one-way screw 6 is rotatably connected inside the fixing frame 5. A slider 7 is threadedly connected to one end of the first one-way screw 6. A top plate 10 is fixedly connected to the top of one side of the slider 7. A fixing plate 11 is fixedly connected to the bottom of one side of the slider 7. A pressure block 13 is provided on the upper side of the fixing plate 11. A telescopic rod 12 is fixedly connected between the top plate 10 and the corresponding pressure block 13. A bottom plate 16 is fixedly connected to the upper side of the workbench 2. A movable frame 17 is provided above the bottom plate 16. Scrapers 22 are symmetrically provided at both ends of the inner side of the movable frame 17. A bidirectional screw 21 is rotatably connected to one side of the inner side of the movable frame 17.

[0024] like Figure 1-3As shown, each fixed frame 5 is fixedly connected with a first limiting rod 8, and each slider 7 is slidably connected to the corresponding first limiting rod 8. A first knob 9 is rotatably connected to one side of each fixed frame 5 at the position corresponding to the first one-way screw 6. One end of each first one-way screw 6 passes through the side wall of the corresponding fixed frame 5 and is fixedly connected to the corresponding first knob 9. A spring 14 is sleeved on the outside of each telescopic rod 12. Both ends of the spring 14 are fixedly connected to the corresponding top plate 10 and pressure block 13, respectively. A lifting rod 15 is fixedly connected to one end of each pressure block 13. Initially, each pressure block 13 abuts against the corresponding fixed plate 11 to clamp the two ends of the vacuum bag opening. Rotating the first knob 9 at both ends drives the corresponding first one-way screw 6 to rotate, which in turn drives the corresponding slider 7 to slide laterally along the first limit rod 8. This allows for flexible adjustment of the slider 7's position according to the width of the vacuum bag. Lifting the corresponding lifting rod 15 compresses the corresponding telescopic rod 12 and spring 14, placing the two sides of the vacuum bag opening between the corresponding pressure block 13 and fixing plate 11. Releasing the lifting rod 15 allows the corresponding telescopic rod 12 and spring 14 to return to their original length and extend. The pressure block 13 and fixing plate 11 then hold the bag sides in place, preventing the bag opening from shifting during later air extraction and improving stability.

[0025] like Figure 1-3 As shown, a second one-way screw 18 is rotatably connected to one end of the upper side of the workbench 2, and a second limiting rod 19 is fixedly connected to one end of the upper side of the workbench 2. One end of the moving frame 17 is slidably connected to the second limiting rod 19, and a limiting block is fixedly connected to the top of the second limiting rod 19. One end of the moving frame 17 is threadedly connected to the second one-way screw 18, and a second knob 20 is fixedly connected to the top of the second one-way screw 18. Initially, the scrapers 22 are all located in the center of the moving frame 17. The two ends of the bidirectional screw 21 are respectively threadedly connected to the corresponding scrapers 22. A third knob 24 is rotatably connected to one side of the moving frame 17 at the position corresponding to the bidirectional screw 21. One end of the bidirectional screw 21 passes through the moving frame 17. The side wall of 7 is fixedly connected to the third knob 24. The inner side of the moving frame 17 is fixedly connected to the third limiting rod 23. One end of the scraper 22 is slidably connected to the third limiting rod 23. The vacuum bag containing the accounting vouchers is placed on the base plate 16. The second knob 20 is rotated, thereby driving the second one-way screw 18 to rotate, which in turn drives the moving frame 17 to move downward along the second limiting rod 19 until the bottom side of the scraper 22 abuts against the vacuum bag body. Then the third knob 24 is rotated, thereby driving the two-way screw 21 to rotate, which in turn drives the scraper 22 at both ends to move in opposite directions along the third limiting rod 23, scraping and pressing the vacuum bag containing the accounting vouchers to prevent the accounting vouchers from wrinkling.

[0026] Working principle: In use, the accounting vouchers to be sealed are placed in a vacuum bag, and the vacuum bag containing the accounting vouchers is placed on the base plate 16. Then, the opening of the vacuum bag is passed through the gap between the sealing strips 3, and the suction nozzle 4 is inserted into the opening of the bag. The first knobs 9 at both ends are turned, thereby driving the corresponding first one-way screw 6 to rotate, which in turn drives the corresponding slider 7 to slide laterally along the first limit rod 8. This allows for flexible adjustment of the position of the slider 7 according to the width of the vacuum bag. The corresponding lifting rod 15 is lifted, thereby compressing the corresponding telescopic rod 12 and spring 14, placing the two sides of the vacuum bag opening between the corresponding pressure block 13 and fixing plate 11. The lifting rod 15 is released, thereby restoring the telescopic rod 12 and spring 14 to their original extension. The pressure block 13 and fixing plate 11 are then used to compress the telescopic rod 12 and spring 14. 11. Press the sides of the bag to prevent the bag opening from shifting during later air extraction, thus improving stability. Turn the second knob 20 to drive the second unidirectional screw 18 to rotate, which in turn drives the moving frame 17 to move downwards along the second limit rod 19 until the bottom side of the scraper 22 abuts against the body of the vacuum bag. Then turn the third knob 24 to drive the bidirectional screw 21 to rotate, which in turn drives the scrapers 22 at both ends to move in opposite directions along the third limit rod 23, flattening and pressing the body of the vacuum bag containing accounting documents to prevent wrinkles from forming on the accounting documents. Then the external vacuum packaging machine body 1 operates to extract air from the vacuum bag using the air extraction nozzle 4. After extraction, the sealing strip 3 is heated and pressed to seal the bag. Finally, the vacuum bag containing the accounting documents is removed to complete the sealing operation.
