[0026] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0027] Reference Figures 1 to 3 As shown, a conveying and correction mechanism for a medicine bag printing machine is provided, including a double-sided guide rail automatic correction mechanism 2 that can move laterally on the worktable. A hand-expanding shaft 1 for placing medicine bag rolls is installed on the worktable. The double-sided guide rail automatic correction mechanism 2 is movably arranged above the hand-expanding shaft 1. The double-sided guide rail automatic correction mechanism 2 is provided with a conveying structure 3 and a double-rail clamping structure 4.

[0028] In this embodiment, the medicine bag roll is placed on the hand-expanding shaft 1, then passes through the conveying structure 3, then through the double-rail clamping structure 4, and finally is conveyed to the bag outlet platform to complete the bag outlet. During the conveying process, bag body deviation is inevitable. The double-sided guide rail automatic correction mechanism 2 detects the bag body deviation in real time and makes timely fine adjustments.

[0029] In some embodiments of this utility model, the double-sided guide rail automatic correction mechanism 2 includes a fixedly installed crossbeam 21 and roller frame 22. A sliding block 23 is provided at the bottom of the crossbeam 21. The roller frame 22 is movably connected to the bottom of the crossbeam 21 through the sliding block 23, so that the roller frame 22 can move back and forth along the length direction of the crossbeam 21. The conveying structure 3 and the double-rail clamping structure 4 are both set on the roller frame 22. The synchronous belt is driven by the motor module, which drives the sliding block 23 to move back and forth on the crossbeam 21, thereby driving the roller frame 22 to move accordingly. The hand-expanding shaft 1 is fixed on the workbench, that is, the starting position of the medicine bag roll is fixed. The conveying structure 3 and the double-rail clamping structure 4 may cause the bag to deviate during the conveying process. Therefore, the movement of the roller frame 22 drives the conveying structure 3 and the double-rail clamping structure 4 to move together, so as to realize the automatic correction of the bag.

[0030] Furthermore, a guide rail 221 is vertically arranged on one inner side of the roller frame 22, and a movable block 222 is arranged on the guide rail 221. The movable block 222 is fixedly connected to a connecting plate 223, and the other end of the connecting plate 223 is connected to the printing platform 224 through which the medicine bag roll passes, so that the printing platform 224 can be raised and lowered. Moving the movable block 222 causes the printing platform 224 to be raised and lowered, thereby controlling the printing distance and ensuring printing accuracy. The movement of the movable block 222 will change the height of the entire "conveying path", allowing the height of the bag to be finely adjusted when it enters the printing area. The equipment has an independent adjustment structure in both the X and Z directions.

[0031] In some embodiments of this utility model, the end of the connecting plate 223 away from the movable block 222 is connected to the double-rail clamping structure 4 so that the double-rail clamping structure 4 can be raised and lowered. While the printing platform 224 is raised and lowered, the double-rail clamping structure 4 also follows the connecting plate 223 in raising and lowering.

[0032] In some embodiments of this utility model, the double-track clamping structure 4 includes a first roller 41, a second roller 42, a third roller 43, a fourth roller 44, a fifth roller 45, and two symmetrical horizontal plates 46. The two horizontal plates 46 are arranged inside the roller frame 22, one of which is fixedly connected to the connecting plate 223. One end of the first roller 41 and the fourth roller 44 are connected to one side of the roller frame 22, and one end of the second roller 42 and the fifth roller 45 are connected to one of the horizontal plates 46. The first roller 41 and the fourth roller 44 are respectively arranged directly above the second roller 42 and the fifth roller 45. The third roller 43 is raised and lowered between the first roller 41 and the fourth roller 44. The raising and lowering of the connecting plate 223 drives the horizontal plates 46 to rise and fall. The second roller 42 and the fifth roller 45 connected to the horizontal plates 46 follow the raising and lowering, forming a clamping conveying channel for stabilizing the bag material and keeping it flat during transmission, preventing bag drifting, shaking, or tilting.

[0033] Furthermore, the two ends of the third roller 43 are connected to mating parts 47, and the horizontal plate 46 is provided with a groove 461 for the mating parts 47 to be inserted. The horizontal plate 46 is provided with an adjustment device 48 for controlling the height of the mating parts 47. The height of the third roller 43 can be adjusted by the adjustment device 48, so that the bag body can be kept flat during the transmission process and will not float, shake or tilt.

[0034] Preferably, the adjusting device 48 consists of a long bolt and a threaded fastener fixed to the horizontal plate 46, and the height of the third roller 43 can be adjusted by twisting the long bolt.

[0035] In some embodiments of this utility model, the conveying structure 3 is disposed at one end of the roller frame 22 near the hand-expanding shaft 1. The conveying structure 3 includes a first conveying roller 31, a second conveying roller 32, a third conveying roller 33, and a fourth conveying roller 34. One end of the first conveying roller 31, the second conveying roller 32, and the third conveying roller 33 are all connected to one side of the roller frame 22. The first conveying roller 31 is disposed directly below the second conveying roller 32, the fourth conveying roller 34 is disposed on one side of the second conveying roller 32, and the third conveying roller 33 is disposed directly above the fourth conveying roller 34. One end of the fourth conveying roller 34 is connected to one of the horizontal plates 46. Each conveying roller is used to convey the medicine bag roll material. The third conveying roller 33 and the fourth conveying roller 34 form a clamping conveying channel to stably clamp the bag material, keeping it flat during transmission and preventing bag floating, shaking, or tilting.

[0036] In some embodiments of this utility model, the double-sided guide rail automatic correction mechanism 2 is also provided with a CCD image recognition window for recognizing pre-printed positioning marks or QR codes on the bag. This window is located in front of the printing area to achieve final position calibration before printing and ensure accurate placement of the printed content.

[0037] In some embodiments of this utility model, the double-track clamping structure 4 is equipped with an electrostatic elimination device to prevent the bag from floating.

[0038] In some embodiments of this utility model, a high-precision photoelectric alignment sensor is provided on the double-sided guide rail automatic correction mechanism 2 to detect the bag offset in real time and make fine adjustments through the motor module.

[0039] The bag itself does not move, but the rollers and conveying rollers move as a whole by moving the roller frame 22.

[0040] The above is a further detailed description of this utility model and should not be considered as a limitation on the specific implementation of this utility model. For those skilled in the art, simple deductions or substitutions without departing from the concept of this utility model are all within the protection scope of this utility model.
