A second guide rod 16 is slidably connected to the middle of the movable sleeve 8. Both ends of the second guide rod 16 are fixedly connected to both sides of the fixed frame 4. A first guide rod 7 is fixedly connected to one side of the push plate 44. A fixed block 15 is slidably connected to the outside of the first guide rod 7. One side of the fixed block 15 is fixedly connected to one side of the fixed frame 4. A connecting frame 31 is fixedly connected to one side of the push plate 44. A scraper plate 32 is provided inside the connecting frame 31. A plug rod 35 is movably connected to one side. One end of the plug rod 35 passes through the connecting frame 31 and is fixedly connected to a movable plate 34. A first spring 33 is fixedly connected to one side of the movable plate 34. One end of the first spring 33 is fixedly connected to one side of the connecting frame 31. The first spring 33 is sleeved on the outside of the plug rod 35. A glue bucket 18 is fixedly connected to one side of the bottom of the processing table 1. A pump body 28 is fixedly connected to the bottom of the glue bucket 18. A connecting pipe 9 is fixedly connected to one side of the pump body 28. One end of the connecting pipe 9 passes through the push plate 44. A third motor 17 is fixedly connected to the top of the glue bucket 18. The output end of the third motor 17 passes through the top wall of the glue bucket 18. A connecting shaft 26 is fixedly connected to the output end of the third motor 17. A stirring rod 27 is fixedly connected to the outside of the connecting shaft 26. A connecting plate 30 is fixedly connected to the outside of the connecting shaft 26. De-glue plates 29 are fixedly connected to both ends of the connecting plate 30.

[0027] The first electric push rod 14 pushes the push plate 44 to the sealing point of the composite bag. The second motor 5 drives the threaded rod 6 to rotate, and the moving sleeve 8 moves accordingly. The moving sleeve 8 moves on the second guide rod 16, which can fix the movement path of the moving sleeve 8. The movement of the moving sleeve 8 drives the push plate 44 to move, and the nozzle on the connecting pipe 9 moves accordingly. The pump body 28 drives the glue inside the glue tank 18 to flow out from the nozzle at the head of the connecting pipe 9 to apply glue to the sealing point of the composite bag. When the third motor 17 works, it drives the connecting shaft 26 to rotate, and the stirring rod 27 and the connecting plate 30 rotate accordingly. At the same time, the glue removal plate 29, which overlaps with the inner wall of the glue tank 18, moves to remove glue. While stirring, the glue is prevented from adhering to the inside of the glue bucket 18. As the push plate 44 moves, it drives the nozzle of the connecting pipe 9 to apply glue to the composite bag. At the same time, the scraper plate 32 moves to spread the glue evenly. By pulling the moving plate 34 outward, the first spring 33 extends, and the plug rod 35 moves outward until it separates from the connecting frame 31. The scraper plate 32 can be removed and cleaned after the glue is scraped off. The cleaned scraper plate 32 is inserted into the connecting frame 31. The first spring 33 pushes the plug rod 35 to connect with the scraper plate 32, which can fix the scraper plate 32. By disassembling and assembling the scraper plate 32, it is easy to remove the glue from the scraper plate 32 after scraping off the glue.

[0028] The operating method and working principle of this device are as follows: Place the composite bag to be sealed on the placement plate 12, and place the part of the composite bag opening to be glued on the rotating plate 10. The second electric push rod 36 drives the positioning block 37 and the pressure rod 42 to move. The pressure rod 42 cooperates with the placement plate 12 to fix the composite bag. At the same time, the first electric push rod 14 drives the push plate 44 to move to the sealing position of the composite bag. The second motor 5 drives the threaded rod 6 to rotate, and the moving sleeve 8 moves accordingly. The moving sleeve 8 moves on the second guide rod 16, which can fix the movement path of the moving sleeve 8. The movement of the moving sleeve 8 drives the push plate 44 to move, and the nozzle on the connecting pipe 9 moves accordingly. The pump body 28 drives the glue inside the glue tank 18 to flow out from the nozzle at the head of the connecting pipe 9, thus sealing the composite bag. When the bag is sealed, glue is applied. When the third motor 17 is working, it drives the connecting shaft 26 to rotate, and the stirring rod 27 and the connecting plate 30 rotate accordingly. At the same time, the glue removal plate 29, which overlaps with the inner wall of the glue bucket 18, moves to stir the glue and prevent it from adhering to the inside of the glue bucket 18. While the push plate 44 moves and drives the nozzle at the head of the connecting pipe 9 to apply glue to the composite bag, the scraper plate 32 moves accordingly to spread the glue evenly. By pulling the moving plate 34 outward, the first spring 33 extends, and the insertion rod 35 moves outward until it separates from the connecting frame 31. The scraper plate 32 can be removed and cleaned after the glue has been scraped off. The cleaned scraper plate 32 is then inserted into the connecting frame 31. The first spring 33 pushes the insertion rod 35 to insert into the scraper plate 32, which can fix the scraper plate 32.

[0029] After the adhesive is applied, the first motor 2 drives the second connecting rod 24 and the second gear 23 to rotate. The second gear 23 meshes with the first gear 3, which drives the first gear 3, the third connecting rod 25 and the second rotating column 22 to rotate. The first rotating column 21 and the second rotating column 22 are rotatably connected, and the first rotating column 21 is rotatably connected with the first connecting rod 20. The second rotating column 22 rotates 180 degrees to the side close to the second gear 23, which drives the rotating plate 10 to rotate 180 degrees to fit on the upper part of the placement plate 12. The placement groove 19 fits with the pressure rod 42, turning the glued part of the composite bag opening to contact the bag opening side, thereby sealing the composite bag.

[0030] After the glue at the sealing point dries, the first motor 2 reverses to drive the rotating plate 10 to the initial position. Then, the positioning plate 39 is pulled down, the second spring 40 is compressed, the telescopic rod 41 retracts, and the fixed rod 38 moves to separate from the pressure rod 42. By pulling the connecting block 43, the pressure rod 42 is driven to move to the outside of the placement groove 19. The pressure rod 42 separates from the positioning block 37. The pressure rod 42 can be removed, and the sealed composite bag can be taken off.
