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.

[0028] Reference Figures 1-4 An embodiment of this utility model is provided: an automatic sealing machine for stationery production, including a support frame 1, a conveying component 24 connected inside the support frame 1, a fixed frame 2 fixedly connected to the top of the support frame 1, an adjustment component 3 for improving versatility connected to the top of the fixed frame 2, and a temperature-adjustable sealing component 13 for improving sealing quality connected to the bottom of the adjustment component 3.

[0029] The temperature-adjustable sealing assembly 13 includes an electric telescopic rod 14, which controls the execution and reset of the sealing action. There are two sets of electric telescopic rods 14, and each set of electric telescopic rods 14 is fixedly connected to a pressure plate 15 at its bottom. Multiple heating wires 16 are connected inside the pressure plate 15. When energized, they generate heat to provide heat for sealing.

A heat-conducting plate 18 is fixedly connected to the bottom of the pressure plate 15 to evenly conduct the heat from the heating wires 16 to the packaging sealing area, ensuring that the sealing is heated evenly.

[0030] Adjustment component 3 includes a fixed housing 4, the bottom of which is fixedly connected to the top of the fixed frame 2. A motor 5 is bolted to the outer side of one end of the fixed housing 4. An electromagnetic brake is externally connected to the output shaft of the motor 5. A threaded rod 6 is fixedly connected to the output shaft of the motor 5 through the fixed housing 4. One end of the threaded rod 6 rotates inside the fixed housing 4 to ensure stability. An active block 7 is threadedly connected to the outside of the threaded rod 6. Adjustment component 3 also includes an active plate 8. Slide grooves 9 are provided on both sides of the fixed housing 4. The active plate 8 slides inside the slide grooves 9 to limit the range of motion of the active plate 8. One end of the active plate 8 is fixedly connected to the side of the active block 7. The other end of the active plate 8 is fixedly connected to a guide plate 10 through the slide groove 9. A guide groove 11 is provided on the top of the fixed frame 2. One end of the guide plate 10 is fixedly connected to a driven plate 12 through the guide groove 11 to ensure the movement path of the driven plate 12. The bottom of the driven plate 12 is fixedly connected to the top of the electric telescopic rod 14. An electric telescopic rod 2 is fixedly connected to the inner side of the support frame 1. 19. One end of the electric telescopic rod 19 is fixedly connected to a centering plate 20 to center and align the stationery packaging during transport, ensuring accurate sealing. Two sets of photoelectric sensors 21 are fixedly installed at the top of the fixed frame 2 by bolts to detect the position of the stationery packaging in real time. The conveying component 24 includes a second motor 25 and a conveying shaft 26. The second motor 25 is fixedly installed on the outside of the support frame 1 by bolts. There are two sets of conveying shafts 26, both of which rotate inside the support frame 1. Both ends of the two sets of conveying shafts 26 pass through the support frame 1. One end of one set of conveying shafts 26 is fixedly connected to the output shaft of the second motor 25. A conveyor belt 27 is installed on the outside of the two sets of conveying shafts 26. A controller 22 is fixedly connected to the outside of the fixed frame 2. The controller 22, the second motor 25, the photoelectric sensor 21, the electric telescopic rod 19, the temperature sensor 17, the heating wire 16, the second motor 25, and the first motor 5 are all electrically connected. The conveyor belt 27 is made of polytetrafluoroethylene, which is high temperature resistant, non-stick, and suitable for sealing environments.

[0031] Working principle: First, the motor 25 of the conveyor assembly 24 drives the conveyor shaft 26 to rotate the conveyor belt 27, transporting the stationery packaging to the sealing station. When the two sets of photoelectric sensors 21 detect that the packaging has reached the designated position, the signal is transmitted to the controller 22. The controller then activates the electric telescopic rod 19 to push the centering plate 20 to center and align the packaging. At the same time, the adjustment assembly 3 starts the adjustment process according to the size parameters of the packaging to be sealed: the motor 5 operates under the command of the controller 22, and its output shaft drives the threaded rod 6 to rotate smoothly inside the fixed housing 4. The active block 7, which is threaded to the threaded rod 6, moves axially, and then drives the guide plate 10 to move through the active plate 8. After the guide plate 10 passes through the guide groove 11 at the top of the fixed frame 2, it drives the driven plate 12 to move synchronously, ultimately driving the temperature control... The sealing assembly 13 is adjusted to be directly above the packaging to be sealed. At this time, the electromagnetic brake outside the output shaft of motor 5 is activated, firmly locking the position of the threaded rod 6 to prevent the sealing assembly from shifting during operation. Subsequently, the two sets of electric telescopic rods 14 extend synchronously, pushing the bottom pressure plate 15 and the heat-conducting plate 18 downward until the heat-conducting plate 18 is tightly attached to the sealing area of ​​the stationery packaging. Then, the multiple heating wires 16 inside the pressure plate 15 are energized and generate heat. The heat is evenly transferred to the packaging sealing area through the heat-conducting plate 18. The temperature sensor 17 at the top of the pressure plate 15 monitors the temperature of the heating area in real time and continuously feeds the data back to the controller 22. The controller 22 dynamically adjusts the power supply of the heating wires 16 according to the preset temperature range corresponding to the packaging material to ensure that the temperature is always in the optimal sealing range. When the sealing operation reaches the preset time, the heating wire 16 stops heating, the electric telescopic rod 14 retracts, and drives the pressure plate 15 and the heat conduction plate 18 to return to their original position and detach from the packaging surface; finally, the conveyor belt 27 continues to operate, transporting the sealed stationery packaging to the discharge end and entering the next production stage.
