The paper box folding mechanism 4 includes a paper box mold 401, an ear folding mechanism 402, a box turning mechanism 403, and a limit rod kit 404 arranged in the conveying track 6. The limit rod kit 404 is arranged between the box turning mechanism 403 and the sealing mechanism 5, and is fixed on the upper part of the conveying track 6 for pressing the folded paper box. The ear folding mechanism 402 is composed of a cylinder 405, an ear folding pressing plate 407 connected to the cylinder 405 through a connecting rod 406, and pressing plates 408 fixed on both sides of the conveying track 6. The ends of the ear folding pressing plate 407 and the pressing plate 408 are set to be arc structures that expand outward. The box turning mechanism 403 includes a box turning plate 409, a connecting frame 410 and a transmission rod 411. A motor 7 is arranged in the base of the body 1. The motor 7 is connected to a transmission shaft 9 through a pulley 8. The transmission shaft 9 is respectively connected to the carton grabbing rod 305 of the carton distribution mechanism 3 and the box turning mechanism 403 of the carton folding mechanism 4. One end of the transmission shaft 9 is connected to a chain 11 on the conveying track 6 through a transmission mechanism 10, and the chain 11 drives the transmission track 6 to operate through a sprocket wheel 12. The glue sealing mechanism 5 includes a glue sealing cylinder 501, a roller 502 is provided on the inner wall of the glue sealing cylinder 501, a glue cylinder 503, a push rod 504, a glue dispensing assembly 505 and a material discharging push plate 506 are arranged at the bottom of the glue sealing cylinder 501, and one end of the connecting frame 410 on the box turning mechanism 403 is connected to the box turning plate 409, and the other end is connected to the push rod 504 of the glue sealing mechanism 5. The glue dispensing assembly 505 includes a cylinder 507 and three glue dispensing claws 508 connected to the cylinder 507, and the three glue dispensing claws 508 are respectively arranged on the other three surfaces of the glue sealing cylinder 501 except for the contact with the conveying track 6. The discharging push plate 506 on the sealing mechanism 5 is arranged on the transmission rod 411 on the box turning mechanism 403. The paper towel conveying mechanism 2 includes a conveying track 6, a paper separation assembly 201 and a paper placing assembly 202. The paper separation assembly 201 is composed of a lever 204 and a paddle 205 driven by a cylinder 203, and the paper placing assembly 202 is composed of a cylinder 206 and a baffle 207. The paper placing assembly 202 is located on the upper part of the conveying track 6. The paper box sleeve mold 401 is respectively arranged on the side walls of the conveying track 6, and the side walls of the conveying track 6 are connected by a screw 13.

[0027] During the implementation process, first adjust the size of the conveying track 6 and the carton sleeve mold 401 to the size of the carton to be folded, place the carton to be folded in the fixed plate 303 of the carton distribution mechanism 3, stack the paper towels in the conveying track 6 in the paper towel conveying mechanism 2, and then start the motor 7 to run. The initial position of the carton grabbing rod 305 on the carton distribution mechanism 3 is that the adsorption component 308 is facing downward. When the motor 7 pushes the carton grabbing rod 305 upward through the transmission shaft 9, when the gear 307 on the carton grabbing rod 305 is engaged with the bar-shaped rack mechanism 306 on the inner wall of the bracket 301, the carton grabbing rod 305 will be flipped 90°, so that the carton adsorption component 308 on the carton grabbing rod 305 is facing upward and gradually approaches the carton to be folded in the fixed plate 303, and contacts the carton to be folded. After that, the suction cup 310 on the suction plate 309 will suck out the single carton to be folded and return it downward. When the gear 307 on the carton grabbing rod 305 is meshed with the bar-shaped rack mechanism 306 on the inner wall of the bracket 301 again, the carton grabbing rod 305 will flip the carton downward and gradually approach the carton sleeve mold 401 on the conveying track 6. At the same time, one end of the transmission shaft 9 in the body 1 is connected to the chain 11 on the conveying track 6 through the transmission mechanism 10. The chain 11 drives the transmission track 6 to continue to operate through the sprocket wheel 12 and reaches the carton in the carton sleeve mold 401. The bottom surface of the carton is at the bottom, and the side surfaces of the four sides are erected. At this time, the remaining top surface and the connecting surface between the side surfaces and the side surfaces have not been folded. The cylinder 405 of the ear folding mechanism 402 pushes the ear folding pressing plate 407 forward and presses it with the pressing plate 407. The plates 408 are docked to fold the four connecting surfaces between the sides of the paper box. At this time, the top surface of the paper box is to be folded. As the conveying track 6 is advanced, the paper separation component 201 of the paper towel conveying mechanism 2 drives the lever 204 and the paddle 205 through the cylinder 203 to divide and isolate the paper towels in equal amounts, and the cylinder 206 of the paper placing component 202 reciprocates the baffle 207. Since the paper placing component 202 is located on the upper part of the conveying track 6, when the baffle 207 is pulled open, the separated paper towels will fall into the paper box in the paper box sleeve mold 401 on the conveying track 6. Then, the connecting frame 410 and the transmission rod 411 of the box turning mechanism 403 push the box turning plate 409 under the action of the transmission shaft 9 of the motor 7, and the box turning plate 409 will fold the top surface of the paper box. The paper box is transported to the limit rod set 404 under the action of the conveying track 6. The limit rod set 404 will prevent the top surface of the paper box from loosening. When it is transported to the position of the push rod 504 with the sealing mechanism 5, the push rod 504 pushes the paper box into the inner cavity of the sealing tube 501 under the action of the connecting frame 410 on the box turning mechanism 403. The three glue dispensing claws 508 of the glue dispensing assembly 505 are initially located in the glue barrel 503. When the cylinder 507 drives the glue dispensing claws 508 to move upward, there is adhesive glue on the glue dispensing claws 508, which contacts and dispenses glue with the three surfaces of the paper box that have not been folded. When the glue dispensing claws 508 push the paper box upward, the paper box contacts the side wall of the sealing tube 501, and the three side surfaces that have not been folded will be fitted with the other surfaces of the paper box. At this time, the entire paper box sealing process is completed.When the paper boxes accumulate more and more in the sealing tube 501 until they exceed the inner cavity of the sealing tube 501, the discharging push plate 506 on the dispensing assembly 505 pushes the paper boxes out under the action of the transmission rod 411 on the box turning mechanism 403.

[0028] It is worth noting that the box-turning plate on the box-turning mechanism, the push rod on the glue dispensing assembly and the discharge push plate are all driven by the connecting frame and the transmission rod on the box-turning mechanism, so these three mechanisms are linked at the same time, and the motor is respectively connected to the transmission rod of the box-turning mechanism, the carton grabbing rod of the carton distribution mechanism and the chain on the transmission track through the transmission shaft to supply power. In addition, by adjusting the screw, the transmission track spacing and the carton sleeve mold spacing can be adjusted to achieve the sealing of cartons of various sizes.

[0029] The beneficial effects of the present invention are: it realizes the edge sealing packaging of paper towels in paper boxes, and realizes automation in the whole process from paper box separation and grabbing, paper box folding, paper towel loading, to paper box gluing and sealing, replacing the manual or semi-automatic packaging process, improving product work efficiency, saving labor costs, and being able to adjust the conveying track and the paper box mold size according to the size of the paper towels in the paper box, thereby realizing the sealing of paper boxes of various sizes and improving the application range of the product.
