[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] In this embodiment, the ultrasonic final sealing device comprises: two fixed guide rails 4, a driving assembly 1, an upper sealing assembly 2 and a lower sealing assembly 3. The two fixed guide rails 4 are arranged vertically and in parallel and fixed on the frame of the device.

[0022] In this embodiment, the driving assembly 1 includes: two driving support seats 16 , a driving motor 11 , a driving shaft 12 , two driving arms 13 , two upper sealing driving rods 15 , and two lower sealing driving rods 14 .

[0023] The drive shaft 12 is fixedly connected to the output shaft of the drive motor 11 through a coupling. The drive support seat 16 is fixed on the equipment frame and is provided with a drive bearing. The drive shaft 12 passes through two drive bearings and can rotate inside the drive bearings. The middle parts of the two drive arms 13 are fixedly connected to the front and rear positions of the drive shaft 12 respectively, and swing with the rotation of the drive shaft 12. The two ends of the drive arm 13 are rotatably connected to the lower end of the corresponding upper sealing drive rod 15 and the lower end of the lower sealing drive rod 14 respectively. The forward and reverse rotation of the drive motor 11 drives the rotating shaft 12 to rotate forward and reverse, thereby driving the drive arm 13, the upper sealing drive rod 15, and the lower sealing drive rod 14 to swing.

[0024] In this embodiment, the upper sealing assembly 2 includes an upper sealing mounting plate 22 , an upper sealing pressing plate 23 , an upper sealing cutter driving unit 24 and an upper sealing cutter 25 .

[0025] The upper sealing mounting plate 22 is slidably connected to the fixed guide rail 4. In this embodiment, the upper sealing mounting plate 22 has two symmetrically arranged upper sealing sliders 22a; the two upper sealing sliders 22a slide on the corresponding fixed guide rails 4 respectively, realizing a slidable connection between the two. The two ends of the upper sealing mounting plate 22 are rotatably connected to the upper end of the upper sealing drive rod 15. In this embodiment, the upper sealing mounting plate 22 has an upper sealing connecting shaft 22b; the upper sealing connecting shaft 22b is embedded in the corresponding shaft hole of the upper sealing drive rod 15, realizing a rotatable connection between the two. The rotatable connection at other positions can also be achieved in this way. The upper sealing drive rod 15 swings, driving the upper sealing mounting plate 22 to move up and down on the fixed guide rail 4. The upper sealing pressure plate 23 is fixed to the upper sealing mounting plate 22; it moves up and down with the upper sealing mounting plate 22.

[0026] In this embodiment, the upper sealing assembly 2 further includes an upper sealing cutter drive unit 24 and an upper sealing cutter 25. The upper sealing cutter drive unit 24 is a cylinder, the fixed end of which is fixed to the upper sealing mounting plate 22; the upper sealing cutter 25 is fixed to the telescopic end of the cylinder. The upper sealing cutter drive unit 24 drives the upper sealing cutter 25 to move up and down, approaching and moving away from the lower sealing cutter 33.

[0027] In this embodiment, the lower sealing assembly 3 includes: a lower sealing mounting plate 31, a lower sealing ultrasonic vibration knife 32, and an ultrasonic transducer 34.

[0028] The lower sealing mounting plate 31 is slidably connected to the fixed guide rail 4. In this embodiment, the lower sealing mounting plate 31 has two symmetrically arranged lower sealing sliders 31a, each of which slides on a corresponding fixed guide rail 4, achieving a slidable connection between the two. The ends of the lower sealing mounting plate 31 are rotatably connected to the upper end of the lower sealing drive rod 14. The lower sealing drive rod 14 swings, driving the lower sealing mounting plate 31 up and down on the fixed guide rail 4.

[0029] The ultrasonic transducer 34 is fixed on the lower sealing mounting plate 22, and the lower sealing ultrasonic vibration knife 32 is fixed on the ultrasonic transducer 34. The ultrasonic transducer 34 converts electrical energy into high-frequency vibration mechanical energy, driving the lower sealing ultrasonic vibration knife 32 to vibrate.

[0030] In this embodiment, the lower sealing assembly 3 further includes a lower sealing cutter 33. The lower sealing cutter 33 is fixed on the lower sealing mounting plate 31 and can work together with the upper sealing cutter 25 to cut the packaging bag.

[0031] Working process of ultrasonic final sealing device:

[0032] After the packaged product enters the ultrasonic final sealing device, Figure 2 The driving motor 11 is started and rotates clockwise, driving the driving shaft 12 and the driving arm 13 to rotate within a certain angle.

[0033] One end of the driving arm 13 drives the upper sealing driving rod 15, thereby driving the upper sealing mounting plate 22 to move downward; the other end of the driving arm 13 drives the lower sealing driving rod 14, thereby driving the lower sealing mounting plate 31 to move upward; until the lower sealing ultrasonic vibrator 32 of the lower sealing component 3 coincides with the upper sealing pressure plate 23 of the upper sealing component 2, and presses the area to be sealed of the packaging bag, the driving motor 11 stops rotating.

[0034] At this point, the ultrasonic transducer 34 begins operating, converting electrical energy into high-frequency vibrational mechanical energy. This drives the lower sealing ultrasonic vibrator 32 to vibrate, which in turn vibrates the sealing area of ​​the packaging bag. This high-frequency vibration bonds the bag together, sealing it. To address the issue of the blade taking up a lot of space, the lower sealing mounting plate 31 utilizes a separate connection to the blade welding head, significantly saving space.

[0035] After sealing is completed, the trimming process is carried out. The upper sealing cutter driving unit 24 drives the upper sealing cutter 25 to move downward, and works together with the lower sealing cutter 33 to cut off the excess scraps, and then the upper sealing cutter driving unit 24 is reset.

[0036] After trimming is completed, Figure 2 As shown, the drive motor 11 starts rotating counterclockwise, driving the drive shaft 12 and the drive arm 13 to rotate in the opposite direction within a certain angle. One end of the drive arm 13 drives the upper sealing drive rod 15, thereby driving the upper sealing mounting plate 22 upward. The other end of the drive arm 13 drives the lower sealing drive rod 14, thereby driving the lower sealing mounting plate 31 downward, returning to their initial positions. The drive motor 11 stops rotating, completing the final sealing operation.

[0037] It should be noted that the technical effects of the present invention can be achieved by swapping the upper and lower sealing components 2 and 3. Similarly, the upper sealing cutter 25 is fixed and the lower sealing cutter 33 is provided with a cutter drive unit 24 to complete the trimming process.

[0038] The embodiments described above are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
