The glue cutting component 346 is elastically connected to the sealing core frame 341 through a knife holder. The knife holder drives the glue cutting component 346 to extend and cut the sealing tape.

[0063] The carton sealing device 30 also includes a guide plate assembly, which includes an upper guide plate 351 and a lower guide plate 352. The upper guide plate 351 and the lower guide plate 352 are respectively disposed on the upper and lower sides of the sealing machine core frame 341. The guide plate assembly guides the carton to circumferential contact with the sealing machine core 344 and the pressing machine core 345.

[0064] When the carton passes through the sealing station 13, the guide plate assembly guides the carton to circumferential contact with the sealing core 344 and the pressure sealing core 345. The sealing core 344, which extends into the sealing station 13, first contacts the front end of the carton body, attaching sealing tape to the front end. As the pushing device 20 pushes the carton, the carton body squeezes the sealing core 344, causing the sealing core support rod 342 to rotate, which in turn drives the sealing core 344 to retract and contact the connection between the upper and lower carton flaps, attaching sealing tape to the connection. The pushing device 20 then pushes the carton to the pressure sealing core. When the sealing mechanism 345 separates, the sealing mechanism 344 extends into the sealing station 13 under the action of elastic force, and attaches the sealing tape to the rear end of the carton. At the same time, the carton contacts the knife holder during the pushing process, pushing the knife holder back into the sealing mechanism frame 341. After the carton passes through, the knife holder loses the pushing force of the carton, causing the tape-cutting component 346 to pop out and cut the sealing tape. Meanwhile, the pressing mechanism 345 contacts the front end of the carton, the connection between the upper and lower carton pages, and the rear end of the carton in sequence during the carton's advancement, pressing the sealing tape onto the carton and improving the sealing firmness.

[0065] Furthermore, the carton sealing device 30 also includes a second roller assembly, which includes a roller lifting adjustment frame 361, a roller seat fixing plate 362, a second roller seat 363, and a second unpowered roller 364. The roller lifting adjustment frame 361 is fixed to the top of the sealing machine core frame 341. The roller seat fixing plate 362 is connected to the roller lifting adjustment frame 361 through a groove and fastener, so that the roller seat fixing plate 362 can be adjusted in the height direction of the roller lifting adjustment frame 361. The second roller seat 363 is fixed to the bottom of the roller seat fixing plate 362, and a plurality of second unpowered rollers 364 are linearly arrayed at the bottom of the second roller seat 363. The second unpowered rollers 364 are used to contact the top of the carton, limit the height of the carton, and restrict the carton to the tray frame 11.

[0066] The tail sealing device 40 and the head sealing device 30 have the same structure and are arranged opposite each other on both sides of the pallet frame 11. This is understood by those skilled in the art and will not be described in detail here.

[0067] The sealing component of the carton sealing machine in this embodiment is mainly responsible for pushing out the folded carton and sealing it during the pushing process. Finally, it is output to the roller equipment through the carton outlet 14. After the carton is folded, the lifting push plate 23 of the pushing device 20 rises. The pushing drive component 21 drives the lifting push plate 23 to push the carton towards the carton outlet 14. The carton enters between the pressure bar assembly of the head pressing device 50 and the tail pressing device 60 to prevent the sides of the carton from opening on their own and affecting the conveying of the carton. After entering the pressure bar assembly area for a certain distance, it will pass between the first roller assembly of the head pressing device 50 and the tail pressing device 60. The first unpowered rollers 552 in linear array on both sides cooperate with the pushing device 20 to clamp and convey the carton. Then, the carton is sealed with tape by two sealing components. The head sealing device 30 and the tail sealing device 40 are each provided with a second roller assembly. The two sets of second unpowered rollers 364 press against the carton surface for conveying to prevent the carton from jumping during the conveying process and affecting the sealing quality. The box head pressing device 50, box tail pressing device 60, box head sealing device 30, and box tail sealing device 40 are respectively installed on the four adjusting screws of the adjusting device. The height of the pressing and sealing can be adjusted by the screws to adapt to cartons of different heights. The box tail adjusting base plate 82 can also be adjusted by the box tail adjusting screw 83 to adapt to cartons of different widths. The four sets of non-powered rollers provide rolling contact while restricting the position of the cartons, reducing wear on the carton surface. This process is repeated to complete the automated sealing process, replacing the manual sealing process and improving production efficiency. The sealing position is precise, the sealing tape adheres well to the carton, and the sealing quality is high. The structure is compact and the layout is reasonable, making it particularly suitable for the sealing needs of small carton sealing machines. Although only some components and embodiments of this application have been illustrated and described, many modifications and changes (e.g., variations in the size, dimensions, structure, shape and proportion, installation arrangement, material use, color, orientation, etc. of the various elements) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0068] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
