Description

Technical Field

[0001] This utility model belongs to the field of mixing equipment technology, specifically relating to a liquid mixing, turning and shaking device for volumetric flasks. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In the fields of biomedicine, chemical analysis, and pharmaceuticals, uniform mixing of solutions is essential to ensure the accuracy and efficiency of subsequent testing and use. Therefore, uniform liquid mixing is a core step in experimental and production processes. However, manual mixing often presents challenges for operators in precisely controlling the inversion angle and shaking frequency, leading to uneven mixing. This not only prolongs the experimental cycle but also increases the need for repeated operations. Furthermore, significant differences in operator technique can introduce human error, affecting the reliability, consistency, and reproducibility of experimental results. Manual operation also carries a high risk of liquid leakage, potentially causing direct contact with toxic or corrosive chemicals, resulting in serious safety hazards and environmental pollution.

[0004] While existing automated equipment can improve efficiency, the poor synchronization of mechanical parts can easily lead to accidental spillage of liquid or violent vibration of the equipment during the mixing process. This not only reduces the mixing effect but may also damage the equipment or interrupt the experiment. In addition, traditional automated equipment generally lacks integrated cleaning functions, making it difficult to completely remove residual liquid. This can easily cause cross-contamination between different batches of samples, which not only contaminates the experimental environment but may also lead to inaccurate test data.

[0020] like Figures 1-4 As shown, this embodiment provides a liquid mixing, turning and shaking device for volumetric flasks, including a base 5, a frame 6, a drive assembly and a control cabinet 1. The control cabinet 1 is equipped with a control board and control circuit, and the bottom of the base 5 is equipped with an anti-slip pad.

[0021] like Figure 1 and Figure 2 As shown, a support base is provided at one end of the base 5, and a drive component is installed at the other end. The frame 6 is located between the support base and the drive component.

[0022] Specifically, frame 6 consists of two upright plates and a base plate. The two upright plates are vertically mounted on the sides of the base plate. Threaded downward pressure rods 2 are vertically installed on the inner sides of the two upright plates of frame 6, providing vertical adjustment. Frame 6 is connected to the drive assembly and support base via a pivot. A volumetric flask tray 8 is fixedly mounted on the bottom of frame 6, i.e., the inner bottom surface, to stably support the bottom of the volumetric flask. The volumetric flask fixing frame 9 is linked to the downward pressure rods 2 via a slider, allowing rotation of the downward pressure rods 2 to drive the fixing frame to fix the volumetric flask and move it up and down along the rod axis.

[0023] In addition, a soft silicone sealing plate 4 is installed on the side of the volumetric flask holder 9 facing the volumetric flask tray 8 to provide cushioning and sealing during compression; while on the opposite side, an elastic clamping element 3 is provided.

[0024] Specifically, the elastic clamping components are installed at the four corners of the volumetric flask holder 9 and connected to the sliders on the volumetric flask holder 9. This component can automatically adapt to volumetric flasks of different sizes and apply uniform clamping force during the pressing process. During the downward pressure process, the elastic clamping components can use their own elastic deformation characteristics to ensure that a uniform and stable clamping force is applied to the bottle body on the entire clamping contact surface, effectively preventing the volumetric flask from shifting or tipping over during the pressure process.

[0025] like Figure 3As shown, the outer sides of the two upright plates of the frame 6 are provided with rotating shafts. The drive components include a pressing motor and a stepper motor. The pressing motor is connected to the pressing screw 2. The pressing motor controls the two pressing motors simultaneously through the motor driver to drive the pressing screw 2 to move. The motor driver is connected to the control board. The stepper motor is connected to the rotating shaft on the outer side of the frame 6 through a coupling.

[0026] Specifically, to support rotational movement and enhance structural stability, the drive assembly includes two pressure motors and one stepper motor. Each pressure motor is directly connected to its corresponding pressure lead screw 2 via a coupling. The motor driver can simultaneously drive both pressure motors, thereby causing the pressure lead screw 2 to perform linear up-and-down movement. The motor driver is connected to a control board, which sends commands for unified control. The stepper motor is connected to the rotating shaft on the outside of the frame 6 via a flexible coupling to achieve stable driving of the rotating shaft.

[0027] In addition, the stepper motor is equipped with an angle sensor connected to the control board to monitor the deflection angle of the motor shaft and adaptively adjust the forward and reverse rotation of the stepper motor to prevent the control circuit wiring harness from getting tangled when the motor shaft rotates.

[0028] like Figure 4 As shown, a water pump mounting bracket 7 is also provided on the base 5. A certain distance is maintained between the water pump mounting bracket 7 and the base 5 to facilitate heat dissipation and reduce vibration. The bottom of the water pump mounting bracket 7 is connected to the base 5 through a connecting plate to ensure the stability and durability of the connection. A flushing tray 10 is provided between the frame 6 and the base 5. The flushing tray 10 and the base 5 are detachably connected. The flushing tray 10 is used to effectively collect the liquid generated during the flushing process. The flushing tray 10 and the base 5 are detachably connected and fixed by buckles or bolts, which facilitates daily cleaning, maintenance and replacement.

[0029] The working principle of this utility model: The volumetric flask is placed on the tray at the bottom of frame 6. The downward motor drives the downward screw 2 to rotate, causing the fixing frame to descend. The elastic clamping parts at the four corners of the fixing frame automatically deform after contacting the flask, evenly pressing the flask body. At the same time, the silicone sealing plate 4 provides a buffer seal. After fixing, the control board starts the stepper motor, which drives frame 6 to rotate and shake around the axis through the coupling. The angle sensor monitors the motor deflection angle in real time, and the control board automatically adjusts the motor's forward and reverse rotation accordingly to prevent the wiring harness from getting tangled.

[0030] During rinsing, the water pump injects liquid into the volumetric flask. Waste liquid generated during the inversion process is collected by the rinsing tray 10 at the bottom. After shaking, the volumetric flask can be released and removed by rotating the screw 2 in the opposite direction.

[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
