[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figure 1-Figure 5As shown, an automatic sealing machine for stationery packaging includes a workbench 101, a conveying trough is provided on the top of the workbench 101, a guide frame 102 is connected to the workbench 101 by screws, a guide mechanism is provided in the guide frame 102, the guide frame 102 is located behind the conveying trough, a conveying mechanism is provided in the conveying trough, a bracket 402 is provided on one side of the guide frame 102, a lifting mechanism is provided at the front end of the bracket 402, a blanking mechanism is provided below the bracket 402, and the blanking mechanism includes a blanking spring 601, the blanking spring 601 is fixedly connected to the top of the workbench 101, a limiting ring 602 is welded on the top of the blanking spring 601, the limiting ring 602 is hollow, and symmetrical movable grooves 603 are provided on the inside of the limiting ring 602, and a limiting spring 604 is welded at one end of the movable grooves 603 away from each other. The ends of the positioning springs 604 close to each other are fixedly connected with a protrusion 605, and the front end of the limiting ring 602 is connected to the blanking rod 8 by a screw. The lifting mechanism drives the limiting ring 602 to rise, thereby driving the blanking rod 8 to move, and the auxiliary block 7 contacts and squeezes the protrusion 605, causing the limiting spring 604 to deform and then recover the deformation, so that the protrusion 605 plays a limiting role on the auxiliary block 7. After the sealing is completed, the auxiliary block 7 pulls the blanking rod 8 up through the limiting ring 602, so that the blanking spring 601 is stretched, and the blanking rod 8 stirs the sealing part upward to prevent the heated part of the packaging bag from sticking to the heating plate 403, which is convenient for subsequent blanking. At the same time, the auxiliary block 7 squeezes the protrusion 605 to cause the limiting spring 604 to deform, and then the protrusion 605 separates from the auxiliary block 7, and the blanking spring 601 recovers the deformation and drives the limiting ring 602 to reset.

[0025] The lifting mechanism includes an electric telescopic rod 501, which is connected to the front end of the bracket 402 by bolts. The bottom of the electric telescopic rod 501 is connected to a movable plate 502 by bolts. The bottom of the movable plate 502 is fixedly connected to a lower pressure plate 503. When the packaging bag moves below the movable plate 502, the electric telescopic rod 501 drives the movable plate 502 to descend, causing the lower pressure plate 503 to move toward the heating plate 403 to press the packaging bag. As the movable plate 502 descends, it drives the auxiliary block 7 to move downward.

[0026] The rear end of the movable plate 502 is connected to an auxiliary block 7 via screws, and the bottom of the auxiliary block 7 is inclined.

[0027] The guide mechanism includes a fixed rod 201 , which is connected to the guide frame 102 via screws. A roller 202 is rotatably connected to the front end of the fixed rod 201 .

[0028] The conveying mechanism includes a conveying motor 301, which is connected to the front end of the workbench 101 by bolts, and a movable rod is rotatably connected in the conveying trough, and the front end of the movable rod is connected to the output shaft of the conveying motor 301 by a coupling, and the movable rod is connected to the conveyor belt 302, and a plurality of partitions 303 are connected to the conveyor belt 302 by screws. The packaging bag is put into the gap between the upper and lower rollers 202 at one end of the guide frame 102, and placed on the conveyor belt 302 and between the two partitions 303, so that the conveying motor 301 drives the conveyor belt 302 to move intermittently, and the conveyor belt 302 drives the partitions 303 to prevent the packaging bag from deviating. As the packaging bag moves, the part to be sealed rolls with the multiple rollers 202, which plays a guiding and positioning role.

[0029] An auxiliary plate 401 is fixedly connected to the top of the workbench 101 , and a heating plate 403 is connected to the top of the auxiliary plate 401 by screws. The heating plate 403 is located at the front end of the bracket 402 , and the bracket 402 is connected to the top of the auxiliary plate 401 by bolts.

[0030] Working principle: When in use, the packaging bag is put into the gap between the upper and lower rollers 202 at one end of the guide frame 102, placed on the conveyor belt 302 and located between the two partitions 303, so that the conveying motor 301 drives the conveyor belt 302 to move intermittently, and the conveyor belt 302 drives the partitions 303 to prevent the packaging bag from deviating. As the packaging bag moves, the part to be sealed rolls with multiple rollers 202, which plays a guiding and positioning role. Then, when the packaging bag moves to the bottom of the movable plate 502, the electric telescopic rod 501 drives the movable plate 502 to descend, so that the lower pressure plate 503 moves toward the heating plate 403 to press the packaging bag. As the movable plate 502 descends, it drives the auxiliary block 7 to move downward, so that The auxiliary block 7 contacts and squeezes the protrusion 605, causing the limit spring 604 to deform and then recover the deformation, so that the protrusion 605 plays a limiting role on the auxiliary block 7. Then the movable plate 502 drives the lower pressure plate 503 to rise to complete the sealing. The movable plate 502 drives the auxiliary block 7 to rise, so that the auxiliary block 7 pulls the discharge rod 8 to rise through the limit ring 602, so that the discharge spring 601 is stretched, and the discharge rod 8 lifts the sealing part upward to avoid the heating part of the packaging bag from sticking to the heating plate 403, which is convenient for subsequent discharge. At the same time, the auxiliary block 7 squeezes the protrusion 605 to deform the limit spring 604, and then the protrusion 605 separates from the auxiliary block 7, and the discharge spring 601 recovers the deformation and drives the limit ring 602 to reset.
