Working principle: as shown in fig. 8, when the first sensor 10 detects that the carton 100 to be sealed and opened moves to the designated position of the linear conveying mechanism 2, the feedback signal gives the system control push mechanism 3 to start to act, the push mechanism 3 starts to apply a pushing force to the left side of the carton 100 to be sealed, which advances along the running direction of the linear conveying mechanism 2, and the carton 100 advances along the running direction of the conveying belt of the linear conveying mechanism 2 under the combined action of the pushing force of the push mechanism 3 and the friction force under the linear conveying mechanism 2, and moves towards the direction approaching to the box folding mechanism 4.

As shown in fig. 9, the carton 100 runs under the combined action of the pushing mechanism 3 and the linear conveying mechanism 2 until touching the tongue pressing frame at the left end of the box folding mechanism 4, so that the cover folding of the upper opening right cover of the carton 100 is completed.

As shown in fig. 10, the carton 100 continues to move in the direction directly under the folding mechanism 4, and at the same time, when the second sensor 20 detects that the carton 100 moves to a designated position directly under the leftmost outer edge of the folding mechanism 4, the second sensor 20 feeds back a signal to the folding mechanism 4 to further control the tongue-breaking cylinder at the upper left end to extend to drive the tongue-breaking arm to rotate and press down, so that the folding of the left cover of the carton 100 is completed.

As shown in fig. 11, the operation of folding the left and right covers of the upper opening of the carton 100 is completed, then the carton 100 continues to move in the direction right below the folding mechanism 4 under the combined action of the pushing force of the pushing mechanism 3 and the friction force of the linear conveying mechanism 2, and then the front and rear covers of the carton 100 respectively touch the guide compression bars at the left inlet of the folding mechanism 4 at the same time, so that the folding of the front and rear covers of the upper opening of the carton 100 is completed.

As shown in fig. 12, the carton 100 continues to move in the direction directly below the box folding mechanism 4 under the combined action of the pushing force of the pushing mechanism 3 and the friction force of the linear conveying mechanism 2, and simultaneously the latch opening cylinder at the left upper end of the box folding mechanism 4 is retracted and reset.

As shown in fig. 13, when the third sensor 30 detects that the paper box 100 to be sealed enters the left side of the taping mechanism 5 to be in contact with the sealing machine core, the third sensor 30 feeds back a signal to the lifting and pressing wheel mechanism 6, controls the front lifting and pressing wheel assembly 61 and the rear lifting and pressing wheel assembly 62 to simultaneously press down on the upper surface of the paper box 100 to be sealed, and applies a downward force on the upper surface of the paper box 100 to be sealed so as to increase the friction force between the paper box 100 and the conveying belt of the linear conveying mechanism 2, and simultaneously ensures that the paper box 100 cannot move up and down when sealing the adhesive tape.

As shown in fig. 14, the carton 100 to be sealed is then moved in the direction of the tape sealing machine core of the tape applying mechanism 5 under the combined action of the friction force of the linear conveying mechanism 2 and the pressing force of the lifting pressing wheel mechanism 6, and the pushing mechanism 3 starts to reset back until the whole carton 100 comes out from the right outlet of the tape applying mechanism 5 through the tape sealing machine core.

Thus, the overall action flow of the linear sealing glue on the upper opening of the carton 100 is completed.

The above embodiments are preferred embodiments of the present invention, and all similar structures and equivalent modifications are intended to fall within the scope of the present invention.
