[0086] The driving box 510 is fixedly connected to the side of the connecting box 410, and the inner side surface of the driving box 510 is fixedly connected with a driving motor 511 corresponding to the transmission rod 460, and the output end of the driving motor 511 is drivingly connected with a driving shaft 512 fixedly connected to the end of the transmission rod 460, and the side of the driving shaft 512 is rotatably connected to the inner side surface of the driving box 510, and the inner side surface of the driving box 510 is rotatably connected with a connecting screw rod 513 corresponding to the conveying rod 414, and the bottom of the side of the connecting screw rod 513 is fixedly sleeved with a worm gear 514, and a power motor 530 is arranged at the bottom of the inner side surface of the driving box 510, and the output end of the power motor 530 is drivingly connected with a transmission shaft 531, and the side of the transmission shaft 531 is fixedly sleeved with a worm gear 532 meshing with the worm gear 514.

[0087] The adjusting seat 570 is slidably connected to the inner side of the driving box 510, and the connecting screw 513 passes through the inside of the adjusting seat 570. The side of the adjusting seat 570 is rotatably connected to a linkage rod 571 fixedly connected to the side of the adjacent conveying rod 415. The side of the linkage rod 571 is rotatably connected to a sliding block 572 slidably connected to the inner side of the driving box 510, and the side of the sliding block 572 is slidably connected to the inner side of the connecting box 410. A linkage gear 573 is fixedly sleeved on the side of the linkage rod 571 away from the conveying rod 415, and the two linkage gears 573 are meshed for transmission. The inner side of the adjusting seat 570 is slidably connected to a screw-on ring 574 screwed together with the side of the connecting screw 513. The outer contour of the cross section of the screw-on ring 574 is a polygon. The top surface of the screw-on ring 574 is fixedly connected to a connecting spring 575 fixedly connected to the inner top surface of the adjusting seat 570.

[0088] The connection belt 520 is fixedly connected to the bottom surface of the driving box 510 , and a Japanese-shaped buckle 521 is provided at one end of the connection belt 520 of one driving module 500 .

[0089] In a specific implementation, the connecting belt 520 of one driving module 500 can be passed around the machine body assembly 200, and then the connecting belt 520 of the other driving module 500 can be passed through the inside of the Japanese-shaped buckle 521, so that the cutting module 400 and the driving module 500 are fixed on the machine body assembly 200 through the connecting belt 520, and the printer can be lifted and moved by the lifting rod 412, and the driving motor 511 can drive the driving shaft 512 to rotate, and the driving shaft 512 can drive the transmission rod 460 to rotate, so that the cutting blade 471 is driven to rotate through the transmission rod 460;

Then, the label paper can be pressed against the cutting piece 471 by the abutment roller 432, and cut by the cutting piece 471. The conveying rod 415 moves upward along with the label paper, so that it is convenient to pass the label paper through the inside of the cutting module 400, which is beneficial for the subsequent cutting of the label paper. When the label paper first enters the inside of the connecting box 410, after the conveying rod 415 moves to the top of the inner side of the connecting box 410, the label paper can be conveyed in reverse so that the cutting piece 471 cuts the end of the label paper. Then, the cut label paper is passed through the inside of the connecting box 410 again by the conveying rod 415. At this time, the cutting piece 471 can continue to cut the label paper longitudinally.

The feeding rod 415 rotates, and the upper and lower adjacent feeding rods 1 414 and the feeding rod 415 rotate in the same direction, so that the label paper can smoothly enter the inside of the feeding rod 415. When the connecting screw 513 rotates to move the feeding rod 415 upward, the two connecting gears 590 will be disengaged. After the feeding rod 415 moves to the top of the inner side of the connecting box 410, the transmission gear 561 will engage with the adjacent linkage gear 573. At this time, the connecting rod 560 can drive a linkage rod 571 to rotate through the transmission gear 561 and the linkage gear 573, so that the two feeding rods 415 continue to rotate to transport the label paper.

[0094] Support seats are fixedly provided inside the drive box 510 corresponding to the power motor 1 530 and the power motor 2 540, and the power motor 1 530 and the power motor 2 540 are supported respectively by the two support seats, and the transmission shaft 1 531 and the transmission shaft 2 541 both rotate with the inner side surfaces of the adjacent support seats, and the transmission shaft 1 531 and the transmission shaft 2 541 are supported respectively by the two support seats.
