A passage opening is also provided at the center of the bottom of the base and the annular groove. A set of straight drive bars located at the passage opening is provided at the bottom of the receiving block. The drive group includes a drive turntable, a drive cylinder installed at the drive end of the drive turntable, and a drive block installed at the drive end of the drive cylinder. The drive block enters the passage opening through the through hole under the lifting drive of the drive cylinder, and the drive groove at the end of the drive block is engaged with the drive bar. When the drive turntable starts to rotate, the drive bar of the drive block drives the receiving block and the annular groove to rotate. When the drive cylinder starts to drive the lifting, the drive block drives the receiving block to guide the lifting within the annular groove.

4. A batch dosing and solution preparation device for a static compounding center according to claim 3, characterized in that, A set of guide holes is also provided on the annular conveyor belt between the two sets of docking fixtures. When a set of docking fixtures rotates to dock with the turntable transition piece, a set of guide holes rotates to the dosing and liquid preparation station. At the dosing and liquid preparation station, the drive end of the sealing group is used to pass through the guide holes and be placed in the cleaning tank for cleaning.

5. A batch dosing and solution preparation device for a static compounding center according to claim 4, characterized in that, The sealing assembly includes a sealing cylinder and a transfer block that is installed at the end of the sealing cylinder. The sealing cylinder is used to drive the transfer block to rise and fall, and a set of sealing blocks is also installed at the end of the transfer block away from the sealing cylinder. The end of the sealing block is provided with a sealing head corresponding to the bottle opening.

6. A batch dosing and solution preparation device for a static compounding center according to claim 5, characterized in that, The conveyor belt transition piece is used to install a set of selection disks on the frame of the ring conveyor belt. The selection disks are driven to rotate by the selection motor. Multiple sets of sealing groups and multiple sets of original liquid medicine bottles are also installed on the circumference of the selection disks. The sealing groups and original liquid medicine bottles are distributed at intervals.

7. A batch dosing and solution preparation device for a static compounding center according to claim 6, characterized in that, A second set of selection disks is also installed on the frame. The second set of selection disks is driven to rotate by a second selection motor. The drive group and the cleaning tank are fixedly distributed along the circumference of the second set of selection disks. When the drive end of the blocking group passes through the guide hole and needs to be cleaned, the second selection motor drives the cleaning tank to align with the blocking group. When the medicine needs to be mixed after the medicine is added, the second selection motor is activated to drive the drive group to align with the blocking group.

8. A batch dosing and solution preparation device for a static compounding center according to claim 7, characterized in that, The second selection plate is also equipped with a set of drying tanks, which are located between the cleaning tank and the drive group. The drying tanks are used to rotate the sealing head to a position below the sealing head after the sealing head has been cleaned in the cleaning tank, so as to perform drying and blowing operations on the sealing head.

9. A batch dosing and solution preparation device for a static compounding center according to any one of claims 6-8, characterized in that, At the drug dispensing station, a set of ejector cylinders is also provided on the frame. The ejector cylinders are used to push the medicine bottle fixture between the right-angle guides and push the medicine bottle fixture onto the turntable transition piece of the next set of drug dispensing units or push it out of the sterile chamber.

10. A batch dosing and solution preparation device for a static compounding center according to any one of claims 1-8, characterized in that, The turntable transition component includes a fixed part located at the center and a rotating part surrounding the fixed part and rotating around it. The rotating part has two sets of outwardly opening work station slots evenly arranged in the circumference. The medicine bottle tooling is fed to the rotating part through the opening of the work station slot. The fixed part is also provided with a push-in cylinder, which is used to push the medicine bottle tooling from the opening of the work station slot to the conveyor belt transition component.
