[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, an economic management certificate vacuum packaging device includes a vacuum packaging box 1, a control panel 2 is fixedly installed on the side of the vacuum packaging box 1, a cover plate 3 is hingedly installed on the top of the vacuum packaging box 1, a packaging machine 4 is fixedly installed on the inner wall of the cover plate 3, a placing table 5 is fixedly installed inside the vacuum packaging box 1, and an anti-wrinkle component 6 and a pressing component 7 are installed inside the vacuum packaging box 1.

[0022] It should be noted that, after the voucher is placed in a vacuum bag and the packaging machine 4 is started, the air in the vacuum bag will be extracted to form a negative pressure state. After the air is extracted, a heating device is used to seal the vacuum bag to complete the vacuum packaging work. The vacuum packaging box 1, cover plate 3, packaging machine 4, placement table 5, anti-wrinkle component 6 and pressing component 7 arranged above have the function of preventing the economic management voucher from wrinkling during packaging.

[0023] The anti-wrinkle component 6 includes a groove 601 located inside the vacuum packaging box 1, a servo motor 602 is fixedly installed on the left inner wall of the groove 601, two threaded rods 603 are rotatably installed inside the groove 601, and pulleys 604 are fixedly installed on the outer surfaces of the two threaded rods 603. The two pulleys 604 are transmitted through a belt 605. Threaded blocks 606 are fixedly installed on the outer surfaces of the two threaded rods 603, and rollers 607 are rotatably installed on the opposite sides of the two threaded blocks 606. After the fixed voucher is packaged, the servo motor 602 is turned on and the two threaded rods 603 are driven to rotate at the same time through the cooperation between the belt 605 and the pulley 604. The rotation of the two threaded rods 603 drives the roller 607 to move through the threaded block 606, so that the roller 607 rolls and presses the packaged voucher again, further eliminating the tiny wrinkles that may exist on the voucher and ensuring the smooth appearance of the voucher.

[0024] The groove 601 is located around the placement table 5, and both ends of the roller 607 are fixedly connected to the surface of the threaded block 606 through a bearing seat, so that the roller 607 can also achieve a rotation effect during the movement, rolling and pressing the voucher, and the bottom of the roller 607 is on the same horizontal plane as the surface of the placement table 5.

[0025] The pressing assembly 7 includes four L-shaped plates 701 located inside the vacuum packaging box 1, and movable rods 702 are movably installed inside the four L-shaped plates 701. The outer surfaces of the four movable rods 702 are sleeved with reset springs 703, and the bottoms of the four movable rods 702 are fixedly installed with pressing plates 704. The four movable rods 702 are pulled to drive the four pressing plates 704 away from the surface of the placement table 5. Then, the economic management voucher is placed on the placement table 5, and the four movable rods 702 are released. The elastic force of the reset springs 703 is used to reset the pressing plates 704 to fix the voucher.

[0026] The four L-shaped plates 701 are each provided with a through hole adapted to the movable rod 702 , and the four movable rods 702 are all slidably connected to the through hole. The provision of the through hole allows the movable rod 702 to be movably connected to the L-shaped plate 701 through the through hole.

[0027] The tops of the four reset springs 703 are fixedly mounted on the inner wall of the L-shaped plate 701, and the bottoms of the four pressing plates 704 are in contact with the top of the placement table 5. The pressing plates 704 are reset by the elastic force of the reset springs 703, which can ensure that the voucher is subjected to uniform and moderate pressure during the packaging process, thereby protecting the voucher from damage.

[0028] When implementing, follow these steps:

[0029] 1) When in use, the four movable rods 702 are pulled at the same time to drive the four pressing plates 704 away from the surface of the placement table 5;

[0030] 2) Then put the economic management voucher in a vacuum bag, and then put it on the placement table 5, loosen the four movable rods 702, and use the elastic force of the reset spring 703 to reset the pressing plate 704 to fix the voucher;

[0031] 3) Restart the packaging machine 4, which will extract the air in the vacuum bag to form a negative pressure state. After the air is extracted, the vacuum bag is sealed using a heating device to complete the vacuum packaging work;

[0032] 4) Then, the four movable rods 702 are pulled to drive the four pressing plates 704 away from the surface of the placement table 5, and the servo motor 602 is turned on to drive the roller 607 to move and rotate, so that the roller 607 rolls and presses the packaged voucher again.

[0033] To summarize, the economic management certificate vacuum packaging equipment, by setting the cooperation between the L-shaped plate 701, the movable rod 702, the reset spring 703 and the pressing plate 704, pulls the four movable rods 702 at the same time, drives the four pressing plates 704 away from the surface of the placement table 5, and then places the economic management certificate on the placement table 5, loosens the four movable rods 702, and uses the elastic force of the reset spring 703 to reset the pressing plate 704 to fix the certificate. The elastic force of the reset spring 703 is used to reset the pressing plate 704, which can ensure that the certificate is subjected to uniform and moderate pressure during the packaging process, protect the certificate from damage, and adopt a fixed pressing method when packaging the economic management certificate to avoid wrinkles.

[0034] Furthermore, by providing the anti-wrinkle component 6, after the fixed voucher is packaged, the servo motor 602 is turned on to drive the roller 607 to move and rotate, so that the roller 607 rolls and presses the packaged voucher again, further eliminating the tiny wrinkles that may exist on the voucher, ensuring the smooth appearance of the voucher, improving its overall aesthetics and professionalism, and ensuring the smoothness of economic management work.
