A batch of mother liquid bottles are fixed on the mother liquid bottle fixture by using the mother liquid bottle clamp. After the mother liquid bottles are placed, the mother liquid bottle fixture is reinserted into the slide rail and then fixed on the mother liquid bottle fixture installation assembly. Then the mother powder revolution device causes the two supporting drive bases to rotate, and the powder on one side of the supporting drive base is rotated. The powder bottle shaking and rotating device and the mother liquid bottle shaking and rotating device are the parts where the powder bottle and the mother liquid bottle are set. The mother powder revolution device makes the support driving base on one side turn to the automatic dispensing robot, and the support driving base on the other side turns to the original position of the support driving base on one side. After the turning is completed, the next batch of powder bottles and mother liquid bottles are placed on the support driving base on the other side. At the same time, the automatic dispensing robot starts to perform the dispensing operation. The first servo motor with a reducer rotates the powder bottle shaking and rotating device through the first powder synchronous wheel, the powder synchronous belt, the second powder synchronous wheel, and the first rotating shaft, so that the bottle head of the powder bottle located on the powder bottle shaking and rotating device is tilted downward, and the liquid medicine in the powder bottle is re-weighted.

After the injection of the medicine in the mother liquid bottle is completed, the powder bottle shaking and rotating device rotates again to make the medicine in the mother liquid bottle and the medicine in the powder bottle The liquid is accelerated to merge by the operation of rotating and shaking. After the rotating and shaking operation is completed, the powder bottle returns to its original position. The automatic dispensing robot uses the dissolver to extract the fused liquid from the powder bottle, and then injects it into the mother liquid bottle that has been extracted. After the fused liquid is completely extracted from the powder bottle, the powder bottle shaking and rotating device will rotate to bring the powder bottle close to the vertical stand, and then release the clamp. The powder bottle falls onto the guide plate under gravity and slides along the inclined surface of the guide plate to the bottle recovery area. After completing a batch of dispensing operations, the mother powder revolution device again causes the two support drive bases to turn, and the positions of the support drive bases on both sides, the powder bottle shaking and rotating device, and the mother liquid bottle shaking and rotating device are reversed.The supporting driving machine base, the powder bottle shaking and rotating device, and the mother liquid bottle shaking and rotating device on the other side cooperate with the automatic dispensing robot to perform the dispensing operation, and new powder bottles and mother liquid bottles are placed on the supporting driving machine base, the powder bottle shaking and rotating device, and the mother liquid bottle shaking and rotating device on one side, and the operation is cyclical.

[0032] A powder tensioning wheel adjustment assembly 55 is provided on the support frame 12, and a powder tensioning wheel 56 is provided on the powder tensioning wheel adjustment assembly 55, and the powder tensioning wheel 56 is transmission-connected to the powder synchronous belt 15; a mother liquid tensioning wheel adjustment assembly 57 is provided on the outer side of the support frame 12, and a mother liquid tensioning wheel 58 is provided on the mother liquid tensioning wheel adjustment assembly 57, and the mother liquid tensioning wheel 58 is transmission-connected to the mother liquid synchronous belt 18. Since the powder timing belt 15 is prone to being stretched and loosened after a certain period of work, in order to avoid this situation, the present invention is designed with a powder tensioning wheel adjustment component 55. The powder tensioning wheel adjustment component 55 can swing up and down according to the tension of the powder timing belt 15, and utilizes the powder tensioning wheel 56 to keep the powder timing belt 15 in a taut state to ensure the normal transmission of the powder timing belt 15. Similarly, the mother liquid tensioning wheel adjustment component 57 utilizes the mother liquid tensioning wheel 58 to keep the mother liquid timing belt 18 in a taut state to ensure the normal transmission of the mother liquid timing belt 18.

[0033] A first photoelectric switch sensor 59 is provided on the support frame 12, a photoelectric switch sensing sheet 60 is provided at the other end of the first rotating shaft 13, and a second photoelectric switch sensor 61 is provided at the bottom of the fixing flange 35 of the mother powder revolution sensing sheet. The combination design of the first photoelectric switch sensor 59 and the photoelectric switch sensing sheet 60 is based on the principle of automation design. The first photoelectric switch sensor 59 is the on-off power control switch of the first servo motor 7, which plays a role in stopping the rotation movement of the powder bottle shaking and rotating device 2. Similarly, the second photoelectric switch sensor 61 is the on-off power control switch of the third servo motor 42, which plays a role in stopping the mother powder revolution device 4.

[0034] A plurality of spring pressing blocks 62 are disposed on the powder bottle clamp 22 . A spring 63 is disposed between the spring pressing block 62 and the powder bottle clamp 22 . The spring pressing block 62 is located between the two clamping members 25 . In the process of discarding the powder bottle, since the bottle head sizes of different powder bottles are different, after the two clamping members 25 are opened, the powder bottle may still hang between the two clamping members 25 due to the excessively large bottle head. Therefore, the combination design of the spring pressing block 62 and the spring 63 is used to make the powder bottle detach from the clamping member 25. When the powder bottle is placed on the powder bottle clamp 22, the bottleneck of the powder bottle pushes the spring pressing block 62 and is clamped by the two clamping members 25. At this time, the spring 63 is kept in a compressed state, and the powder bottle is fixed on the powder bottle clamp 22. When the two clamping members 25 no longer clamp the bottleneck of the powder bottle, the spring pressing block 62 pushes the powder bottle outward under the elastic force of the spring 63, and the powder bottle is completely pushed away from the clamping member 25.

[0035] A first protective shell 64 is provided on the second connecting plate 47, and the mounting plate 48, the solenoid valve 49, the first joint 50, the nozzle pressing member 51, the nozzle adapter 52, the nozzle 53, and the second joint 54 are all located in the first protective shell 64. A fixing member 65 is provided between the first protective shell 64 and the mounting plate 48 to fix the two together. A through hole 66 is provided on the first protective shell 64, and the through hole 66 is aligned with the nozzle 53. A second protective shell 67 is provided on the support frame 12. Both the first protective shell 64 and the second protective shell 67 play a protective role to prevent external factors from affecting the normal operation of the internal parts of the present invention. Under the protection of the second protective shell 67, the disinfectant sprayed from the nozzle 53 sprays the powder bottle through the through hole 66.

[0036] There are four powder bottle clamps 22, which are evenly distributed along the circumference of the powder bottle clamp fixing assembly 20; there are more than three mother liquid bottle clamps 31, which are all arranged on the upper surface of the mother liquid bottle fixture 30. The number of powder bottle clamps 22 and mother liquid bottle clamps 31 is freely set according to the production standard requirements, and at least the basic dispensing amount of a single batch must be completed.
