[0025] See also Figure 7 , used for the bottle cutting mechanism of the dispensing machine, the guide conveying mechanism 57 includes a guide frame 571, a lifting plate 572, a push block 573, a protrusion 574, and a threaded rod 575. The guide frame 571 is fixed to the front end of the movable frame 53, the lifting plate 572 is slidably matched with the top right end of the push block 573, the push block 573 is fixedly connected to the top of the protrusion 574, the threaded rod 575 is movably connected to the inside of the protrusion 574, and the right end of the threaded rod 575 is threadedly matched with the guide frame 571.
[0026] In some embodiments, the cross-section of the guide frame 571 is a U-shaped structure, and the lifting plate 572 slides with the inner side of the guide frame 571. The right end of the guide frame 571 is a cavity-shaped structure, and the right front end of the guide frame 571 is provided with a scale value, which is convenient for understanding the height of the lifting plate 572, thereby accurately determining the slot position of the ampoule bottle 7.

The bottom cross-section of the lifting plate 572 is consistent with the inclination angle of the top slope of the push block 573. By moving the push block 573 to the right end, the lifting plate 572 is pushed up and the height of the lifting plate 572 is adjusted.
[0027] In summary, when in use, the bottle cutting mechanism for the dispensing machine is placed horizontally and can be docked with the bottle breaking mechanism; By rotating the threaded rod 575 clockwise, the threaded rod 575 is threadedly driven on the inner side of the guide frame 571, and the push block 573 is driven to move to the right end through the protrusion 574. While the push block 573 moves, it slides with the lifting plate 572 to lift the lifting plate 572 upward, thereby changing the height of the lifting plate 572. The height of the lifting plate 572 can be understood through the scale value on the right front end of the guide frame 571, and the support height of the manipulator 6 can be changed, thereby accurately determining the slotting position of the ampoule bottle 7. Next, the movable frame 53 is moved to slide horizontally on the guide rail 52. Since the ampoule bottle 7 moves horizontally, the cutting depth of the bottle mouth of the ampoule bottle 7 can be adjusted by simply changing the moving distance of the ampoule bottle 7 to the rear end. When it moves to the appropriate position, the screw rod 542 is rotated counterclockwise so that the screw rod 542 is threadedly engaged with the threaded seat 541 and transmitted to the right end of the threaded seat 541, so that the screw rod 542 drives the movable block 544 to move synchronously. The movable block 544 moves and drives the limiting top block 543 to swing to the right end, so that the limiting top block 543 and the right end of the protective cover 51 are supported and limited, thereby positioning the movable frame 53. Then, the ampoule bottle 7 is clamped by the manipulator 6 and conveyed to the top of the lifting plate 572 by the moving mechanism, and fits with the top of the lifting plate 572. Then, the manipulator 6 drives the ampoule bottle 7 to move horizontally to the rear end. As the ampoule bottle 7 moves, the ampoule bottle 7 contacts and is positioned with the left front end of the conveying auger roller 56. At the same time, the driving motor is started to drive the rotating shaft 82 to rotate. When the rotating shaft 82 rotates, the tungsten steel knife 85 is driven to rotate, so that the neck of the ampoule bottle 7 can be cut and grooved. The bottom and top of the tungsten steel knife 85 are provided with a knife wheel pressure plate 84 to ensure the stability of the operation of the tungsten steel knife 85. After the bottom knife wheel pressure plate 84, the tungsten steel knife 85, and the top knife wheel pressure plate 84 are successively installed on the outer wall of the rotating shaft 82, the locking nut 83 is installed on the outer wall of the rotating shaft 82, and the protective cover 51 can cover the ampoule bottle 7 to prevent debris from splashing during cutting, and a vacuum cleaner can be used to absorb the debris. After the cutting is completed, the robot 6 releases the clamping of the ampoule bottle 7, and then moves to the front end to exit. At the same time, the servo motor 55 drives the conveying auger roller 56 to transmit. The conveying auger roller 56 transmits the ampoule bottle 7 in a spiral shape, and cooperates with the guide plate 58 to convey the ampoule bottle 7 out of the protective cover 51, and then enters the bottle breaking structure to perform the bottle breaking operation, thereby increasing the dispensing efficiency of the subsequent dispensing structure.
