[0023] Working Principle: During operation, the operator places the paper bag 3 onto the conveyor 2 and operates it via the intelligent display screen 12. The intelligent control system controls the conveyor 2 to move the paper bag 3 to the position of the transfer mechanism 4. Then, the intelligent control system controls the second electric slide rail 42 in the transfer mechanism 4 to move the L-shaped frame 43 downward via the slider, so that the first suction cup 45 downwards to attract the paper bag 3. Then, the L-shaped frame 43 is controlled to move upwards to reset. Then, the first electric slide rail 11 moves the transfer mechanism 4 and the positioning mechanism 5 simultaneously, so that the transfer mechanism 4 moves directly above the correction mechanism 6. Next, the intelligent control system controls the second electric slide rail 42 to move the first suction cup 45 via the slider to place the paper bag 3 onto the moving plate 67, and the third suction cup 68 attracts the paper bag 3. Finally, the intelligent control system controls the transfer mechanism 4 and the positioning mechanism 5 to move simultaneously. The positioning mechanism 5 is reset. Then, the intelligent control system determines the position of the paper bag 3 through the camera 57, and then controls the drive motor 553 to work based on the information transmitted by the camera 57. The drive motor 553 drives the spur gear 554 to rotate. Then, the spur gear 554 drives the gear ring 552 to rotate. The gear ring 552 drives the rotating ring 551 to rotate. The rotating ring 551 drives the rotating frame 63 to rotate under the restriction of the support rod 62 through the wedge blocks 555 on both sides. The rotating frame 63 drives the moving disk 67 to rotate through the spring insert rod 64. The moving disk 67 drives the third suction cup 68 to rotate through the connecting sleeve 69. Finally, the paper bag 3 is adjusted to the correct direction, that is, the handle of the paper bag 3 is facing the first electric slide rail 11. If the paper bag 3 delivered by the transmitter 2 is already in the correct direction, there is no need to start the drive motor 553.Subsequently, the intelligent control system controls the third electric slide rail 52 to move the fixed frame 53 downwards via the slider until the U-shaped rod 565 contacts the surface of the paper bag 3. During the downward movement of the fixed frame 53, the two wedge blocks 555 respectively squeeze a pressure block 65 and insert it into the rotating frame 63, causing the pressure block 65 to drive the spring rod 64 downwards, and through the L-shaped plate 66, drive the moving disk 67 downwards as well, providing space for the transfer of the bottom folding part of the paper bag 3. The paper bag 3 is then held in place by the third suction cup 68. Next, the intelligent control system controls the micro motor 561 to work, and the micro motor 561 drives the lead screw 562 to rotate through the transmission wheel 564. The movement causes the U-shaped rod 565 to move. As the U-shaped rod 565 moves, the folded part at the bottom of the paper bag 3 is moved from the top to the bottom, and the top of the paper bag 3 becomes flat. At this time, the U-shaped rod 565 is located below the slide groove 584. Then, the intelligent control system controls the electric push rod 581 to extend, driving the frustum 582 and the suction cup part in the second suction cup 583 to move downward until the U-shaped rod 565 is located in the slide groove 584. When the frustum 582 is driven away from the rotating ring 551 by the electric push rod 581, the wedge block 555 is no longer squeezed by the frustum 582 and enters the interior of the rotating ring 551 under the action of the spring rod, thus no longer pressing the pressure block 65. Simultaneously, the spring rod 64 resets under the action of the spring, thereby driving the moving disk 67 to reset upwards. Then, the moving disk 67 and the truncated cone 582 together clamp the paper bag 3, thus achieving the positioning and correction of the paper bag 3 and flattening the surface of the paper bag 3 to ensure the quality of subsequent printing. Afterwards, the intelligent control system controls the second suction cup 583 to suck up the paper bag 3, while the third suction cup 68 does not work. Then, it controls the third electric slide rail 52 to drive the fixing frame 53 to move upwards and remove the paper bag 3 from the correction mechanism 6. Then, it controls the first electric slide rail 11 to move the positioning mechanism 5, so that the paper bag 3 is placed on the conveyor 2 from the correction mechanism 6. At this time, the transfer mechanism 4... An unprinted paper bag 3 is placed in the correction mechanism 6. After the paper bag 3 is positioned and corrected, it is transported to the printer 7 via the conveyor 2 for printing. This completes the printing of one side of the paper bag 3. After the paper bag 3 is printed, it is transported by the conveyor 2 to the flipping mechanism 8. The paper bag 3 enters the storage tank 82 and then rotates under the drive of the drive of the drive wheel frame 81, so that the paper bag 3 is flipped and placed on the other side of the conveyor 2. The paper bag 3 is moved out of the storage tank 82 by the three conveyor belts on the conveyor 2 and input into another set of positioning printing units to complete the printing of the other side. Finally, the printed paper bag 3 is output through the conveyor 2.It should be noted that the intelligent control system, the first electric slide rail 11, the second electric slide rail 42, the third electric slide rail 52, the first suction cup 45, the second suction cup 583, and the third suction cup 68 are all existing technologies, and the joint operation of each mechanism can be programmed through the intelligent control system to ensure the smooth operation of the paper bag 3 printing process. Further details will not be elaborated upon here.

[0024] In some embodiments, a plurality of push rods 21 are provided on the transmitter 2 located between the flipping mechanism 8 and another set of positioning printing units. The push rods 21 are able to ensure that the paper bag 3 is pushed out of the storage slot 82 as the conveyor belt of the transmitter 2 moves.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
