The first gear 405 drives the second gear 406 to rotate. The first gear 405 and the second gear 406 drive the corresponding first conveyor rollers 407 to rotate. The two first conveyor rollers 407 convey the tape, and the conveying speed remains unchanged, keeping the tape in a taut state so that the tape is not prone to stacking during the conveying process.

[0027] Working principle:

[0028] When using a fully automatic carton sealing machine with a quick tape changing device to seal a carton, a tape unwinding mechanism 11 is provided on the surface of the main body frame 1. The tape unwinding mechanism 11 can achieve quick tape changing. The specific internal structure and the principle of quick tape changing are the same as those in a carton sealing machine with a quick tape changing device with the patent publication number CN218142497U. Start 6 to drive the cross plate 7 to move, thereby adjusting the height of the second conveyor roller 8, and then sealing cartons of different heights. The tape is released from the inside of the tape unwinding mechanism 11, passes between the two first conveyor rollers 407. The outer wall of the first conveyor roller 407 is provided with an ion film that will not adhere to the tape, and then winds around the top of the second conveyor roller 8;

[0029] Carton conveying stage:

[0030] Place the carton to be sealed on the upper surface of the conveyor belt 2. Start the electric push rod 301. The electric push rod 301 drives the support plate 302 to move. The support plate 302 drives the slide rod 303 and the moving frame 304 to move. The slide rod slides inside the main body frame 1 to guide the movement of the support plate 302. The moving frame 304 drives the roller 305 to move. The roller 305 contacts the outer wall of the carton. Close the electric push rod 301. The roller 305 fits with the carton to prevent the position of the carton from shifting. At the same time, the roller 305 can rotate without affecting the movement of the carton on the conveyor belt 2. When the carton is conveyed on the conveyor belt 2, the position of the carton will not shift, and thus will not affect the sealing effect of the carton;

[0031] Tape conveying stage:

[0032] Start the motor 402. The motor 402 drives the worm 403 to rotate. The worm 403 drives the worm gear 404 to rotate. The worm gear 404 drives the first gear 405 to rotate. The first gear 405 drives the second gear 406 to rotate. The first gear 405 and the second gear 406 drive the corresponding first conveyor rollers 407 to rotate. The two first conveyor rollers 407 convey the tape, and the conveying speed remains unchanged, keeping the tape in a taut state so that the tape is not prone to stacking during the conveying process;

[0033] Sealing stage:

[0034] The air cylinder 6 drives the second conveying roller 8 to move to the same height as the carton. The carton is conveyed on the conveyor belt 2. When one end of the carton is conveyed under the elastic pressing mechanism 10, the tape roll falls on one edge of the carton. The elastic pressing mechanism 10 presses the tape tightly on the continuously conveyed carton under elastic extrusion to seal the carton. After the right end of the carton reaches under the elastic pressing mechanism 10, the tape is cut by starting the shearing mechanism 9, and thus the sealing action of one carton is completed.
