Technical Field

[0001] The utility model relates to the technical field of extraction liquid preparation, and particularly relates to an extraction liquid preparation device. Background Art

[0002] As an important intermediate product, the extraction liquid has a wide range of applications in many fields such as medicine, bioengineering, and food science. It extracts active ingredients from plants, animals, implant materials, or other raw materials through methods such as soaking, impregnating, or dissolving. However, the traditional extraction liquid preparation methods have the following problems:

[0003] Complex operation: Traditional extraction liquid preparation usually needs to be completed under a laminar flow hood to avoid contamination of the sample and its extraction liquid. This process involves multiple steps, including sample preparation, weighing, solvent selection and addition, extraction, oscillation, and subsequent purification.

[0004] High labor cost: Most of the operation processes need to be completed manually, especially in the sample preparation, transfer, and subsequent processing stages. This not only consumes a large amount of human resources but also easily introduces human errors.

[0005] Poor operation accuracy: Since different operation spaces need to be frequently switched during the operation process, this not only increases the operation difficulty but also may cause sample contamination or loss, affecting the accuracy and consistency of experimental results.

[0006] Low efficiency: Manual operation is not only time-consuming but also unable to effectively control the consistency of each sample during batch preparation, limiting the production efficiency. Content of the Utility Model

[0007] The purpose of the utility model is to provide an extraction liquid preparation device, which improves the deficiencies in the traditional method through automated means and improves the efficiency and quality of extraction liquid preparation.

[0016] Further: There is also a weighing device located directly below the sampling device for weighing the implanted samples dropped in the sampling device.

[0017] Further: The displacement device also includes a cap screwing mechanism. The cap screwing mechanism includes a cantilever type three-axis T-shaped guide rail installed in the outer shell and a three-jaw air gripper installed on the cantilever type three-axis T-shaped guide rail.

[0018] Further: The ventilation opening is detachably installed on the main body of the outer shell.

[0019] Further: The storage device includes a storage outer chamber, a conveyor belt, a driving motor, a base, and an extraction tube fixing rack.

[0045] As Figure 6-7 shown: A liquid adding device 3, which is used to add extraction medium into the extraction tube 4.5.

[0047] As Figure 1-3 shown: A displacement device, which is used to complete the displacement of the extraction tube 4.5 among the storage device 4, the sample adding device 2, the liquid adding device 3, and the vibration device 8. It specifically includes a grasping mechanism 5 and a cap screwing mechanism 6. The grasping mechanism 5 includes a rotary cylinder 5.1, a linear guide rail 5.2 vertically installed on the rotary cylinder 5.1, and a gripper 5.3 slidably installed on the linear guide rail 5.2. The gripper 5.3 makes a linear motion on the linear guide rail 5.2 driven by a motor. The cap screwing mechanism 6 includes a cantilever type three-axis T-shaped guide rail 6.1 installed in the outer shell 1 and a three-jaw pneumatic gripper 6.2 installed on the cantilever type three-axis T-shaped guide rail 6.1.

[0048] A weighing device 7 is located directly below the sample adding device 2 and is used to weigh the implant samples falling in the sample adding device 2.

[0049] The working principle of the present utility model is as follows:

[0050] First, the extraction tube 4.5 is placed on the extraction tube fixing rack 4.3 of the storage device 4. The extraction tube fixing rack 4.3 is installed on the base 4.4 and is driven by a driving motor through the conveyor belt 4.2, so as to realize the automatic conveying of the extraction tube 4.5 in and out of the housing 1. The fresh air system is started, and the axial flow ventilator and the detachably installed ventilation opening ensure the cleanliness of the air inside the device, reduce the risk of sample contamination, and improve the quality of the extraction solution.

[0051] Next, the grasping mechanism 5 in the displacement device takes out the extraction tube 4.5 from the extraction tube fixing rack 4.3 through the gripper 5.3. The three-jaw air gripper 6.2 of the capping mechanism 6 moves to the extraction tube 4.5 under the drive of the cantilevered three-axis T-shaped guide rail 6.1, grabs the bottle cap of the extraction tube 4.5 and unscrews the bottle cap. Then, the rotary cylinder 5.1 and the linear guide rail 5.2 of the grasping mechanism 5 jointly drive the gripper 5.3 to move the extraction tube 4.5 with the removed bottle cap under the sampling device 2. The gripper 5.3 places the extraction tube 4.5 on the weighing device 7 directly below the sampling device 2.

[0052] The sampling device 2 precisely adds the implanted sample into the extraction tube 4.5 through the sample feeding pipeline and the vacuum pump 2.2. Specifically, after the vacuum tube is opened, a negative pressure is generated at the air inlet 2.21 of the outlet section 2.12 of the sample feeding pipeline, and the implanted sample in the sample feeding pipeline is sucked towards the outlet section 2.12 and falls from the outlet section 2.12 into the extraction tube 4.5. The weighing device 7 directly below the sampling device 2 precisely weighs the added implanted sample to ensure that the amount of sample added each time is consistent, improving the accuracy of the preparation of the extraction solution.

[0053] Subsequently, the displacement device continues to move the extraction tube 4.5 under the liquid adding device 3. The liquid adding device 3 precisely adds the extraction medium into the extraction tube 4.5 through the extraction medium container 3.1 and the liquid inlet pipe 3.2 extending into the extraction medium container 3.1. It should be noted that the liquid inlet pipe 3.2 is driven by a micro water pump to add liquid to the extraction tube 4.5. The liquid inlet pipe is driven by a micro water pump. The water pump has two ports, one for inlet and one for outlet, which are respectively used for sucking and discharging liquid. Its working principle is to maintain negative pressure / vacuum at the inlet to complete the suction of the liquid. This section is the liquid inlet pipe, which is responsible for extracting the extraction medium; the liquid discharge port forms a slightly positive pressure to complete the discharge of the liquid. This section is the liquid discharge pipe, which is responsible for discharging the extraction medium into the extraction tube.

[0054] After the sampling and liquid adding are completed, the three-jaw air gripper 6.2 of the capping mechanism 6 moves to the extraction tube 4.5 under the drive of the cantilevered three-axis T-shaped guide rail 6.1 and screws the bottle cap back onto the extraction tube 4.5. The displacement device moves the extraction tube 4.5 to the vibration device 8. The vibration device 8 includes a constant temperature vibrator and an extraction tube placement groove 8.1 provided on the constant temperature vibrator. By vibrating, it ensures that the extraction medium is in full contact with the implanted material, maintains suitable temperature conditions, and improves the safety of the extraction process.

[0055] Finally, the shifting device moves the extraction tube 4.5 that has completed the extraction process from the vibration device 8 back to the storage device 4, thus completing the entire extraction liquid preparation process.

[0056] Through the above steps, the extraction liquid preparation device of the present utility model realizes a high degree of automation in the extraction liquid preparation process, significantly reduces the need for manual operation, and lowers the labor cost. At the same time, through the design of the weighing device 7 and the vibration device 8, the accuracy and safety of the operation are improved, ensuring the quality of the extraction liquid. In addition, the application of the fresh air system guarantees a high cleanliness inside the device, reducing the risk of sample contamination.

[0057] The above embodiments are only used to illustrate the technical concept and features of the present utility model, and the purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and shall not be used to limit the protection scope of the present utility model.
