Then the interval between the support plates 605 in the support arm adjusting device 5 is reduced, and the clamp 805 drives the smoke box to move downwards to be placed on the support plates 605; at this point the flaring device 4 is moved toward the carton and the four guide plates 504 are flared to flare the flaps of the carton.

And then the glue spraying device 704 sprays glue, the front folding mechanism 702 positioned at the left side moves backwards, the paper box folds, the push plate in the box pushing device 3 pushes the stacked cigarettes to move transversely, the cigarettes pass through the flaring device 4, enter the paper box under the guidance of the guide plate 504, and the front folding mechanism positioned at the left side limits the cigarettes.

After the cigarettes enter the cartons, the left front folding mechanism 702 and the left rear folding mechanism 701 fold the cartons, and when the front folding mechanism 702 and the rear folding mechanism 701 move away, the left upper folding mechanism 808 folds the cartons, and the left lower folding mechanism 703 folds the cartons.

The right side back flanging mechanism 701 and the front flanging mechanism 702 act to realize the right side front and back flanging of the paper box, the right side lower flanging mechanism 703 acts to realize the right side lower flanging of the paper box, then the right side back flanging mechanism 701 and the right flanging device 702 move away, and the upper flanging mechanism 808 acts to realize the right side upper flanging of the paper box;

and then the pushing arm 1108 of the carton pushing device 11 is driven by a motor to move so as to push the cigarettes filled in the stack, when the two sides of the carton pass through the pressing device 8, the pressing mechanism 903 of the pressing device 8 presses the folded edges on the two sides, the adhesive tape is used for sealing the cartons after passing through the clamping device 9 and the adhesive tape pasting device 10, and the cigarettes after sealing the cartons are pushed out of the carton sealing machine.

According to the embodiment, the other end of the longitudinal conveying mechanism 1 extends out of the frame 13 and is directly abutted to the cigarette outlet of the cigarette wrapping machine, a conveying line is not needed for conveying cigarettes, the occupied area of cigarette packaging is saved, the running requirement of the ultra-small type packaging box sealing machine at the cigarette outlet is met, and the occupation of site space is reduced.

The shaping and lifting device 7 and the automatic feeding device 12 correspond to the top and the bottom of the supporting arm adjusting device 5, the shaping and lifting device 7 and the automatic feeding device 12 are integrated inside the box packing machine, a mechanical arm is not required to be used for transferring and shaping the paper boxes from outside the equipment, and the shaping of the paper boxes and the boxing of cigarettes are finished inside the equipment.

The forming and lifting devices 7 are arranged along the vertical direction of the equipment, so that the reasonable arrangement of the internal space of the equipment is realized, the whole occupied space of the equipment is greatly reduced, the operations of sucking, lifting, forming and the like of box blanks are met, and the design requirement of the ultra-small box packing and sealing machine is met.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
