[0015] The present invention provides a carton sealing machine and a carton sealing process, which have the following beneficial effects:

[0016] (1) In the present invention, when the paper box moves to the bottom between the two clamping plates, the second conveying device moves the paper box between the top conveyor belts, and then the two second tape machines are used to tape the gaps at the two ends of the top edge of the paper box. The second cylinder pushes the vertical plate downward, and the vertical plate moves downward while driving the two clamping plates to move downward, so that the two clamping plates can press down the tape at the two ends of the top edge of the paper box, so that the other half of the tape can be wrapped around the top side of the paper box, thereby achieving sealing of the top of the paper box, which is beneficial to prevent external dust from entering the interior.

[0018] (3) The paper box sealing machine and the paper box sealing process can drive the second threaded rod to rotate by rotating the adjusting handle, and the second threaded rod can drive the slider to move by rotating, and the slider can drive the two conveyor belts to move relative to each other, so that the two conveyor belts can clamp the paper box between them, and thus adjust the width between the conveyor belts. By rotating the third handle, the third handle can drive the third threaded rod to rotate, and the third threaded rod can drive the slide plate to move, so that the slide plate is aligned with the conveyor belt at the top of the second conveying device, which is conducive to making the paper box sealing machine suitable for various sizes of paper boxes.

[0019] This solves the problem that after sealing the box, gaps still remain on both sides of the top cover of the existing box sealing machine, which makes it easy for external dust to enter the interior through the gaps on both sides of the top of the cover, and the top of the paper box can only be sealed in one direction by the tape.

9. A paper box sealing process according to any one of claims 1 to 8, characterized in that: The steps are as follows: S1: placing the paper box to be sealed between the conveyor belts (501) at the top of the first conveying device (1) and the second conveying device (9), and then rotating the adjusting handle (504). The adjusting handle (504) can drive the second threaded rod (503) to rotate while rotating. The second threaded rod (503) can drive the slider (502) to move while rotating. The slider (502) can drive the two conveyor belts (501) to move relative to each other while moving, so that the two conveyor belts (501) can clamp the paper box between them, and then adjust the width between the conveyor belts (501) so that the paper box can maintain stable linear movement when sealing. By rotating the third handle (605), the third handle (605) can drive the third threaded rod (604) to rotate. The third threaded rod (604) can drive the slide plate (606) to move while rotating, so that the slide plate (606) is aligned with the conveyor belt (501) at the top of the second conveying device (9); S2: By rotating the rocker (305) on both sides of the first conveying device (1) and the second conveying device (9), the rocker (305) can drive the first threaded rod (302) to rotate while rotating, so that the first threaded rod (302) can drive the connecting block (301) to move up and down, and the connecting block (301) can drive the lifting beam (10) to move up and down while moving up and down, so that the height of the first adhesive tape machine (4) and the second adhesive tape machine (7) can be adjusted up and down, so that the first adhesive tape machine (4) and the second adhesive tape machine (7) can be attached to the top of the paper box; S3: When the paper box moves to the bottom of the folding mechanism (2), the conveyor belt (501) drives the paper box to continue to move. When the three paperboards on the top of the paper box contact the guide rod (202), they will flip over, so that the three sides of the paper box can be closed. Then, under the push of the telescopic end of the first cylinder (203), the rotating block (205) can drive the lever (204) to rotate, so that the lever (204) can fold and close the remaining side of the top of the paper box. After the top of the paper box is closed, it will pass through the bottom of the first adhesive tape machine (4) and be sealed by the first adhesive tape machine (4), so that the middle seam of the top of the paper box can be closed; S4: The paper box moves to the top of the steering mechanism (6) under the action of the first conveying mechanism, and then, through the blocking of the slide plate (606), the paper box can be aligned with the conveyor belt (501) at the top of the second conveying device (9), and then, through the push of the pneumatic rod (607), the push plate (608) can push the paper box to the top of the second conveying device (9), and the second conveying device (9) moves the paper box between the top conveyor belts (501), and then the gaps at the two ends of the top edge of the paper box are glued with tape through two second tape machines (7); S5: When the paper box moves to the bottom between the two clamping plates (805), the second cylinder (802) pushes the vertical plate (803) downward, and the vertical plate (803) moves downward, which drives the two clamping plates (805) to move downward, so that the two clamping plates (805) can press down the tape at the two ends of the top edge of the paper box, so that the other half of the tape can be wrapped around the top side of the paper box, thereby sealing the top of the paper box, which is beneficial to prevent external dust from entering the interior.
