Description

Technical Field

[0001] The utility model relates to the technical field of shaking devices, and more specifically, the utility model relates to a shaking device with volume determination by shaking. Background Art

[0002] In many fields such as scientific research, chemical analysis, biological detection, and medical testing, it is often necessary to accurately determine the volume and fully shake liquid samples. Volume determination is to ensure that the samples have accurate concentrations and volumes, so as to ensure the accuracy and repeatability of subsequent analysis results. Shaking is to evenly mix various components in the samples to ensure that the detection results can truly reflect the actual situation of the samples;

[0003] In the existing mechanism, the liquid inside the volumetric flask remains on the inner wall of the volumetric flask and the stirring rod. The remaining liquid will deteriorate due to long-term contact with air, thus affecting the subsequent quality.

[0004] After retrieval, a Chinese patent with the authorization announcement number CN222342677U discloses a soaking and shaking device. In this structure, workers pour sufficient water into the shaking cylinder, and pour liquid materials into the shaking cylinder one by one and stir them evenly. Multiple cleaning rods are in sliding contact with the inner surface of the shaking cylinder, thus preventing materials from accumulating on the surface of the shaking cylinder and being unable to be mixed evenly. When the liquid stirring is completed and the inside of the shaking cylinder needs to be cleaned, the water flow in the water pipe flows to the cleaning components of multiple upper fixing frames and multiple stirring rods under the pressure of the continuously incoming water flow. The cleaning ring cleans the multiple cleaning rods, thus preventing the liquid from remaining and deteriorating on the stirring components and improving the production quality of the liquid;

[0005] After retrieval, a Chinese patent with the authorization announcement number CN220496179U discloses a shaking device. In this structure, by setting devices such as a servo motor, a moving rod, a limiting long rod, a limiting short rod, and a sliding plate, when in use, the servo motor drives the circular plate to rotate, thereby driving the moving rod and the sliding plate to move. The sliding plate that moves in a cycle will push the shaking barrel to shake back and forth, achieving the effect of shaking. And by setting devices such as a limiting long rod and a limiting short rod, when the circular plate rotates, the pushing block on the circular plate will first push the limiting short rod to move to one side, and when it continues to rotate, it will then push the limiting long rod to move to the other side, achieving a cyclic and rapid movement, facilitating the rapid cyclic shaking of the shaking barrel and improving its shaking effect.

[0006] However, when this structure is actually used, by achieving stirring inside the shaking cylinder to obtain the shaking effect, for some liquid materials with large property differences that need to be fully mixed, relying only on stirring inside the shaking cylinder may not be able to make the liquid be fully stirred in multiple directions, resulting in the mixing uniformity being difficult to reach a high level and unable to meet some experimental or production scenarios with strict requirements for mixing uniformity.

[0047] The working principle of the present utility model:

[0048] The present utility model is a shaking device with shaking and volume fixing. When the device is in use, open the solenoid valve 20 on one side of the feed pipe 18, and inject the liquid into the shaking cylinder 6 through the feed pipe 18. After injecting an appropriate amount of liquid, close the solenoid valve 20 on one side of the feed pipe 18;

[0050] Then, start the first motor 9. The output end of the first motor 9 drives the rotating shaft 10 to rotate. Since the eccentric wheel 11 is fixedly arranged outside the rotating shaft 10, the eccentric wheel 11 rotates accordingly. The eccentric wheel 11 is slidably connected to the slider 3. During the rotation of the eccentric wheel 11, it pushes the slider 3 to slide up and down reciprocally in the chute 2;

[0051] Meanwhile, start the stepper motor 7 to rotate forward. The stepper motor 7 drives the second rotating rod 8 to rotate. The second rotating rod 8 drives the fixed ring 5 to rotate. And one end of one slider 3 is rotatably provided with a first rotating rod 4. One end of the first rotating rod 4 is fixedly provided with a fixed ring 5, thereby driving the shaking cylinder 6 to shake. When the stepper motor 7 drives the second rotating rod 8 to rotate by a quarter, the stepper motor 7 rotates in reverse, thereby driving the shaking cylinder 6 to swing back and forth reciprocally;

[0052] Then, start the second motor 21. The output end of the second motor 21 drives the stirring rod 22 to rotate. When the stirring rod 22 rotates, the V-shaped stirring strips 28 on its surface stir the liquid in the shaking cylinder 6. And the stirring rod 22 drives the scraping strip 25, the stirring frame 26 and the stirring rod 27 to move together through the support strip 23 and the connecting strip 24;

[0053] The scraping strip 25 can scrape off the liquid adhering to the inner wall of the shaking cylinder 6, enabling the liquid to fully participate in the shaking. The stirring frame 26 and the stirring rod 27 further enhance the stirring effect on the liquid, thereby realizing the comprehensive shaking of the liquid in the shaking cylinder 6;

[0054] When the liquid is shaken evenly, open the solenoid valve 20 on one side of the discharge funnel 19. The shaken and volume-fixed liquid flows out through the discharge funnel 19 and is collected in the corresponding container. When all the liquid has flowed out, close the solenoid valve 20 on one side of the discharge funnel 19.

[0055] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly.
