In this embodiment, when in use, the height of the adapted carton is adjusted by the edge sealing mechanism 7, and the width of the adapted carton is adjusted by the positioning mechanism 6. When the adjustment is completed, the carton is placed on the conveyor belt 3, and the conveyor belt 3 is started to drive the pushing block 4 to push the carton.

In the present embodiment, when the fixed shell 504 moves longitudinally, the shaft column 505, the hollow column 1 506, the shaft column 2 507 and the hollow column 2 508 are driven to move longitudinally accordingly, and contact with the top of the carton to press the carton to prevent the carton from tilting up on both sides. When the carton moves laterally under the push of the pushing block 4, the carton drives the hollow column 1 506 and the hollow column 2 508 to rotate on the shaft column 1 505 and the shaft column 2 507 respectively.

[0025] like Figure 1-2 As shown, the top ends of the two limit screws 503 extend to the outside of the gantry 501, and gears 509 are installed on the tops of the two extended end limit screws 503. Toothed belts 510 are meshingly installed on the outer walls of the two gears 509. A support plate 512 is installed on the top of the gantry 501, and a motor 511 is installed on the top of one of the gears 509, and the motor 511 is installed on the surface of the support plate 512.

[0026] like Figure 1 As shown, the positioning mechanism 6 includes two connecting rods 601, and the two connecting rods 601 are slidably installed on the gantry 501. A plurality of threaded holes 602 are penetrated on the two connecting rods 601. A positioning plate 603 is installed on the side where the two connecting rods 601 are close to each other. Two threaded grooves are provided on the gantry 501, and fixing members 604 are threadedly installed in the two threaded grooves, and the fixing members 604 are threadedly installed on the inner walls of the threaded holes 602. In this embodiment, the two connecting rods 601 slide horizontally on the gantry 501. When the distance between the two positioning plates 603 is adjusted to be close to the width of the carton, the connecting rods 601 and the gantry 501 are locked by the fixing members 604, thereby realizing the conveying positioning of the carton and avoiding displacement.

[0027] In summary, when in use, the height of the adapted carton is adjusted by the edge sealing mechanism 7, and the width of the adapted carton is adjusted by the positioning mechanism 6. When the adjustment is completed, the carton is placed on the conveyor belt 3, and the conveyor belt 3 is started to drive the pushing block 4 to move, and the carton is pushed. During the travel of the carton, it contacts the pressing mechanism 5 and the positioning mechanism 6. When the carton passes through the edge sealing mechanism 7, the carton is glued and sealed by the edge sealing mechanism 7, and the pressing mechanism 5 is pressed to make the sealing stable. The number of pushing blocks 4 can be set and used alternately, so as to achieve efficient edge sealing of cartons of different specifications. The operation is simple and the practicability is strong. Through the two limit screws 503 When rotating, the fixed shell 504 is driven to slide longitudinally on the two limit screws 503 and in the rectangular groove 502, so as to adjust the height of the fixed shell 504. When the fixed shell 504 moves longitudinally, the shaft column 1 505, the hollow column 1 506, the shaft column 2 507 and the hollow column 2 508 are driven to move longitudinally and contact with the top of the carton to press the carton to prevent the two sides of the carton from tilting. When the carton moves laterally under the push of the push block 4, the carton drives the hollow column 1 506 and the hollow column 2 508 to rotate on the shaft column 1 505 and the shaft column 2 507 respectively, and the motor 511 is stably supported by the support plate 512. The motor 511 is started to drive it. The connected gear 509 rotates, and the toothed belt 510 is the transmission center of the two gears 509, so that the two gears 509 rotate synchronously, and the two limit screws 503 rotate synchronously accordingly, and slide horizontally on the gantry 501 through the two connecting rods 601. When the distance between the two positioning plates 603 is adjusted to be close to the width of the carton, the connecting rod 601 and the gantry 501 are locked by the fixing piece 604, so as to realize the conveying positioning of the carton and avoid deviation. By starting the cylinder 1 701 to adjust the height of the tape roll 705 according to the height of the carton, the carton moves horizontally under the cooperation of the conveyor belt 3 and the push block 4. When the carton and the tape roll 705 are 5, the tape of the tape roll 705 will adhere to the side of the carton. As the carton continues to move forward, the tape of the tape roll 705 will break away from the contact with the fixing rod 706 and tilt at an angle. With the cooperation of the hollow column 2 508, the tape adheres to the top of the carton to seal its edge. After the lamination is completed, the cylinder 2 707 is started to drive the rectangular plate 708, the blade 709 and the smoothing block 710 to move downward to cut the tape. As it continues to move downward, the smoothing block 710 will push the tape against the side of the carton, thereby sealing the top of the carton. In addition, the arrangement of the connecting piece 703 and the nut 704 can facilitate the replacement of the tape roll 705.
