The packaging of the carton 28 closes the slit 33 with an adhesive tape 32 and the adhesive tape passes from the first side surface 29 of the carton 28, over the top surface 30, to the second side surface 31. Of course, the bottom surface 34 of the carton 28 also includes corresponding slits (not shown), and the packaging of the carton 28 also includes closing the slits on the bottom surface 34 with tape 32', the tape 32' also being required to pass from the first side surface 29 of the carton 28 to the second side surface 31 through the bottom surface 34 in the same manner as the closure 33 on the top surface 30.

The carton 28 may be placed on the upper box sealing means in an up-down orientation as shown in fig. 7, or may be placed on the respective side box sealing means in a lateral orientation with the top surface 30 and bottom surface 34 on the sides and the first side surface 29 upstream of the second side surface. As will be appreciated by those skilled in the art, the upper and side closure arrangements are substantially identical in construction, with the primary difference being only the orientation in which the components are disposed. For convenience of explanation, the automatic box sealing device according to the present application will be described in detail below by taking the above box sealing device as an example.

The sealing assembly 15 of the automatic sealing device according to the application comprises a sealing roller 16 for applying adhesive tape to the cartons 28, the sealing roller 16 being mounted directly or indirectly on the first frame 19 by means of springs in a position such that the sealing roller can interfere with the cartons conveyed past the sealing roller on the conveyor and the sealing roller 16 can be pressed against three surfaces of the cartons 28 in sequence under pressure by the springs, whereby the sealing roller 16 applies adhesive tape 32, 32' under pressure to the cartons 28.

Specifically, when the carton 28 reaches the position of the box sealing rubber roller 16, the box sealing rubber roller 16 first contacts the first side surface 29 of the carton 28, and as the carton proceeds on the conveying mechanism 1, the box sealing rubber roller 16 applies adhesive tape to a portion of the first side surface 29 under a certain pressure, while the interference between the box sealing rubber roller 16 and the carton overcomes the elastic force of the spring, so that the box sealing rubber roller 16 gradually approaches the slit of the carton on the first side surface 29 and reaches the top surface of the carton where the slit is located, and is pressed against the top surface by the elastic force applied by the spring. As the cartons continue to advance on the conveyor 1, the sealing roller 16 advances along the slit, applying adhesive tape to the slit with a certain pressure by means of the spring. When the end of the slit is reached, the spring force of the spring causes the box sealing glue roller 16 to abut against the second side surface 31 of the carton and continue to apply tape to a portion of the second side surface 31 as the carton continues to advance on the conveyor 1. After a predetermined length of tape is applied to the carton, the seal assembly 15 cuts the tape.

The following description of the automatic carton sealing device according to the present application will be given by way of example of a carton being transported in an up-down orientation on the conveyor 1.

After the carton 28 is completely boxed, the flares are retracted and the conveyor line conveys the carton to the carton sealing device for top sealing with tape to complete the entire carton sealing operation.

Specifically, cartons 28 filled with cigarettes are transported on the transport mechanism 1, clamped between the slide belts 3 of the slide ways 2, 2', from upstream to downstream (right to left in fig. 1), wherein the cartons 28 assume an up-down orientation with the upper flaps in an open state. When the carton 28 approaches the position below the carton pressing member 4, the pressing mechanism 36 is activated, and the first driving cylinder 9 drives the first telescopic rod 8 to extend outwards from the first driving cylinder 9, so that the adjusting rod 7 is driven to pivot around the adjusting seat 6 clockwise, and the carton pressing member 4 moves downwards to press the top of the carton, so that the upper folding piece of the carton 28 is folded to form the gap 33 (fig. 7).

At the same time, as the carton continues to move downstream, the nip 33 is sealed by the platen assembly 15. The adhesive tape 32 is unwound from the adhesive tape roller 13 of the box sealing assembly 15, is fed to the box sealing adhesive roller 16 positioned under the second frame 35 by the plurality of rollers of the adhesive tape feeding assembly 10, and is applied to the carton by the box sealing adhesive roller 16, and after a predetermined length of the adhesive tape is unwound, the adhesive tape is cut by the cutting mechanism.

When the carton 28 reaches the position of the box sealing glue roller 16, the box sealing glue roller 16 first contacts the first side surface 29 of the carton 28, as the carton continues to advance on the conveyor 1, the box sealing glue roller 16 applies adhesive tape under pressure to a portion of the first side surface 29, while the interference between the box sealing glue roller 16 and the carton overcomes the spring force of the spring such that the position of the box sealing glue roller 16 on the first side surface 29 gradually rises up, approaching the slit of the carton, then reaches the top surface of the carton where the slit is located, and is pressed against the top surface by the spring force applied by the spring. As the cartons continue to advance on the conveyor 1, the sealing roller 16 advances along the slit, applying adhesive tape to the slit 33 with a certain pressure by means of the spring. When the end of the slit is reached, the spring force of the spring causes the box sealing glue roller 16 to abut against the second side surface 31 of the carton and continue to apply tape to a portion of the second side surface 31 as the carton continues to advance on the conveyor 1. After a predetermined length of tape is applied to the carton, the seal assembly 15 cuts the tape.

The sealed paper box 28 continues to move forward to reach the second frame 17, the sealing box visual monitor 20 monitors the sealing position of the top of the paper box, and the second driving cylinder 21 drives the second telescopic rod 23 and drives the coding mechanism 24 to code at the top of the paper box, so that the paper box is convenient to trace.
