[0002] Aqueous injections are a type of liquid drug for injection, also known as injectable preparations. They are mainly composed of water and active ingredients and are usually sterile, intended for intravenous, intramuscular, or subcutaneous administration. The processing of aqueous injections requires the use of various raw materials for mixing, necessitating the use of a drug preparation device. Existing drug preparation devices suffer from low mixing efficiency, lack suitable high-efficiency mixing mechanisms, and have inconvenient tank disassembly, making maintenance cumbersome. Furthermore, the devices exhibit poor stability during efficient mixing and agitation, lacking suitable enhanced protective mechanisms. Utility Model Content

A servo motor is connected to one side of the rotating shaft, and a tank body is detachably arranged between the two rotating shafts. Arc-shaped mounting plates are arranged at both ends of the tank body corresponding to the rotating shafts, and positioning rods are arranged at the bottom ends of the two arc-shaped mounting plates. Positioning holes are opened on both rotating shafts corresponding to the positioning rods. Positioning rings are arranged at the bottom of the outer end faces of the two positioning rods, and the positioning rings and positioning rods are threadedly connected. A cover plate is detachably arranged on the upper surface of the tank body, and a stirring mechanism is arranged on the cover plate. A feeding funnel is penetrating through the front side of the upper surface of the cover plate, and a discharge pipe is penetrating through the front side of the lower surface of the tank body.

[0005] The present invention is further configured such that the stirring mechanism includes a stirring shaft, stirring rods and a stirring motor, the stirring shaft is rotatably mounted on the cover plate, multiple stirring rods are provided, and multiple stirring rods are all mounted on the stirring shaft, and the stirring motor is connected to the top of the stirring shaft to realize stirring processing.

[0006] The present invention is further configured such that a first threaded hole is provided on the cover plate, and multiple first threaded holes are provided in the circumferential direction of the cover plate. A second threaded hole is provided on the upper surface of the tank body corresponding to the multiple first threaded holes. The first threaded holes and the second threaded holes are connected by bolts to facilitate the disassembly and assembly of the cover plate.

[0007] The present invention is further provided that the base plate has multiple fixing holes, which facilitates stable installation of the whole.

[0008] The present invention is further configured such that grooves are symmetrically provided on both sides of the front face of the lower end of the base plate, and reinforcing plates can be detachably provided inside the multiple grooves. Reinforcing holes are provided on the multiple reinforcing plates to achieve anti-tipping protection reinforcement.

[0009] The present invention is further configured such that the upper surface of the base plate is provided with a first connecting hole corresponding to the plurality of grooves, and the plurality of reinforcing plates are provided with a second connecting hole corresponding to the first connecting hole. The first connecting hole and the second connecting hole are connected by bolts, which facilitates the disassembly and assembly of the reinforcing plates.

[0010] The present invention is further configured such that reinforcing brackets are symmetrically provided at the bottom of the left and right end faces of the two support plates, and multiple reinforcing brackets are connected to the base plate to improve the connection strength between the support plates and the base plate.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a dispensing device for aqueous injections, which has the following beneficial effects: 1. Through its rotating shaft design, this device not only actively shears materials by driving the stirring shaft and stirring rod with a stirring motor, but also innovatively enables the entire tank to rotate back and forth in a controllable manner under the drive of a servo motor. This "dynamic three-dimensional mixing" mode generates a powerful synergistic effect: the swaying of the tank causes continuous convection and replacement of materials at different levels within the tank, effectively eliminating dead zones in the mixing process; while the internal agitator focuses on localized, powerful crushing and homogenization. The combination of these two aspects significantly improves mixing efficiency and uniformity, making it particularly suitable for the preparation of water-based injection solutions with high viscosity or large density differences, ensuring the ultimate uniformity and stable quality of the drug solution components.

[0012] 2. Through the design of the tank, the tank is connected to the rotating shaft through the arc-shaped mounting plates at both ends. The positioning rod is inserted into the positioning hole for initial positioning, and then the positioning ring connected by threads is used for quick locking and fixation. This realizes the modular connection between the tank and the transmission system. This design makes the installation and disassembly of the tank extremely convenient. It is easy to thoroughly clean, disinfect and maintain the tank after completing a batch of production or changing the type of medicine. It effectively avoids cross-contamination and improves the flexibility and compliance of the equipment.

[0013] 3. Through the design of the reinforcing plate, a detachable reinforcing plate is incorporated beneath the base plate, securely connected to it with bolts. This increases the support area at the bottom of the equipment and the overall weight distribution, lowering the center of gravity. Simultaneously, the reinforcing bracket between the support plate and the base plate further strengthens the rigidity of key load-bearing structures. This combined reinforcement significantly improves the equipment's vibration and overturning resistance during mixing and tank rotation, ensuring stable and safe production processes, and especially guaranteeing the stability of the entire system under high-speed dynamic operation.

Rotary shafts 3 are rotatably mounted on both support plates 2. A servo motor 4 is connected to one side of the rotating shaft 3. A tank body 5 is detachably mounted between the two rotating shafts 3. Arc-shaped mounting plates 6 are provided at both ends of the tank body 5 corresponding to the rotating shafts 3. Positioning rods 7 are provided at the bottom of both arc-shaped mounting plates 6. Positioning holes 8 are provided on both rotating shafts 3 corresponding to the positioning rods 7.

[0020] In this embodiment, the control device has its own control system. The servo motor 4 is started and installed on the corresponding side support plate 2 through its own L-shaped plate. The servo motor 4 drives the side shaft 3 to rotate, so that the tank 5 rotates back and forth relative to the two side support plates 2 on the bottom plate 1. The stirring mechanism stirs the raw materials added into the tank 5 through the feeding funnel 11, so as to achieve efficient mixing and stirring when preparing water injection. After the preparation is completed, the valve of the discharge pipe 12 is opened to discharge the mixed product.

[0021] More specifically, after the device has been used for a long time, the tank body 5 is disassembled and inspected separately. The positioning ring 9 is rotated, and the positioning ring 9 and the positioning rod 7 are threaded together. After the positioning ring 9 is removed, the tank body 5 is disassembled as a whole. After the tank body 5 is inspected, the arc plate is installed on the two sides of the rotating shaft 3, and the positioning rod 7 is inserted into the positioning hole 8. The positioning ring 9 and the positioning rod 7 are threaded together to achieve quick installation and locking.

[0022] Please see Figure 1 , Figure 3 and Figure 4As one embodiment of the stirring mechanism: the stirring mechanism includes a stirring shaft 13, stirring rods 14 and a stirring motor 15. The stirring shaft 13 is rotatably mounted on the cover plate 10. Multiple stirring rods 14 are provided, and all of the multiple stirring rods 14 are mounted on the stirring shaft 13. The stirring motor 15 is connected to the top of the stirring shaft 13. The cover plate 10 is provided with a first threaded hole 16.

[0023] Specifically, the control device has its own control system. When the stirring motor 15 is started, the stirring motor 15 is fixedly installed on the cover plate 10 through its own L-shaped plate. The stirring motor 15 drives the stirring shaft 13 to rotate, thereby rotating multiple stirring rods 14 on the stirring shaft 13 to achieve internal stirring. When the cover plate 10 is installed in relation to the tank body 5, the bolts pass through the first threaded hole 16 and the second threaded hole 17 and are tightened to fix it.

[0024] Please see Figure 1 , Figure 2 and Figure 5 As one method of overall locking: the base plate 1 has a number of fixing holes 18.

[0025] Specifically, bolts are initially installed and locked by passing through multiple fixing holes 18 on the base plate 1 to correspond to the ground. The reinforcing plate 20 is installed in the groove 19. The first connecting hole 22 and the second connecting hole 23 are aligned. Bolts are passed through and tightened to fix the device. After the reinforcing plate 20 is installed, bolts are installed by passing through the reinforcing hole 21 to correspond to the external ground.

[0026] In summary, the overall equipment is in use: When the drug preparation is in progress, the raw materials for drug preparation are added into the tank 5 through the feed funnel 11. The control device has its own control system, which starts the servo motor 4 and the stirring motor 15. The servo motor 4 drives the corresponding side rotating shaft 3 to rotate relative to the support plate 2, realizing the reciprocating rotation adjustment of the tank 5. The stirring motor 15 drives the stirring shaft 13 and the stirring rod 14 to rotate, realizing efficient stirring and mixing, and achieving efficient drug preparation.

[0027] When the device is in the reinforced installation state, the entire device is initially installed to correspond to the external ground. Bolts are tightened through multiple fixing holes 18. After the initial installation, the reinforcing plate 20 is inserted into the groove 19. Bolts are tightened through the first connecting hole 22 and the second connecting hole 23 to achieve the installation and connection of the reinforcing plate 20. After the reinforcing plate 20 is installed, bolts are tightened through the reinforcing hole 21 to correspond to the external ground. The reinforcing plate 20 provides anti-tipping protection for the entire device and improves the overall stability.

[0028] When in maintenance mode, rotate the positioning ring 9. The positioning ring 9 and the positioning rod 7 are threaded together. After the positioning ring 9 is removed, the tank body 5 with the arc-shaped plate is disassembled. The cover plate 10 of the disassembled tank body 5 is then disassembled.
