Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to a vortex mixer. Background Technology
[0002] A medical vortex mixer is a medical experimental instrument that cleverly combines oscillation and vortex. During experiments, to ensure rapid processing of liquids, liquid-solid mixtures, powders, and other substances, it utilizes eccentric rotation to generate vortices in containers such as test tubes, thereby achieving thorough mixing of solutions. However, in existing vortex mixers, the overall position of the mixer can shift excessively during oscillation, leading to liquid overflow from test tubes and other unpredictable effects. Furthermore, existing vortex mixers cannot accommodate test tubes of different diameters and heights, requiring different vortex mixers for different test tube sizes, thus reducing the practicality of a single vortex mixer.
[0003] The function of a vortex mixer is to make objects centrifuge at high speed and shake, so that they are mixed evenly. Therefore, a vortex mixer that can better simulate shaking is needed. Utility Model Content
[0004] The purpose of this invention is to provide a vortex mixer to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A vortex mixer includes a shaking table and a centrifuge. The centrifuge is fixedly mounted on the top of the shaking table. The shaking table includes a fixed plate, a first electric cylinder, a second electric cylinder, a third electric cylinder, and a fourth electric cylinder. The first, second, third, and fourth electric cylinders are respectively located at the four corners of the top of the fixed plate. The top ends of the first, second, third, and fourth electric cylinders are connected to the same support plate. The centrifuge is fixedly mounted on the top of the support plate. Connectors are provided at the top and bottom ends of the first, second, third, and fourth electric cylinders. The first, second, third, and fourth electric cylinders are connected to the fixed plate / support plate through the connectors. The connectors allow both ends of the first, second, third, and fourth electric cylinders to rotate freely.
[0007] By adopting the above technical solution, the first, second, third, and fourth electric cylinders have a faster response speed compared to traditional crank-connecting rod structures or hydraulic structures. The first, second, third, and fourth electric cylinders, which are set at the four corners of the fixed plate, can simulate any shaking trajectory and frequency, making them better suited for centrifuges.
[0008] In a further embodiment, the connector includes a first bearing and a servo motor. The servo motor is disposed on one side of the first bearing. An extension is provided on the inner ring end face of the first bearing. A first gear is sleeved on the extension. A second gear is sleeved on the output shaft of the servo motor. The first gear and the second gear mesh. A mounting plate is fixedly connected to the inner ring of the first bearing. One end of a connecting rod is hinged to the mounting plate.
[0009] By adopting the above technical solution, the other end of the connecting rod is connected to one end of the first electric cylinder / second electric cylinder / third electric cylinder / fourth electric cylinder, so that both ends of the first electric cylinder / second electric cylinder / third electric cylinder / fourth electric cylinder are hinged and fixed. When it is necessary to simulate shaking, the servo motor drives the inner ring of the first bearing to rotate in the same direction and at the same angle, which can simulate different shaking lines. By controlling the rotation speed and the cycle of forward and reverse rotation, more shaking patterns can be simulated.
[0010] In a further embodiment, the four bottom corners of the fixing plate are provided with equal-height pads.
[0011] In a further embodiment, the top plate of the fixing plate is provided with a buffer layer.
[0012] In a further embodiment, a plurality of infrared ranging sensors are provided on the top of the fixing plate.
[0013] In a further embodiment, a vibration detection sensor is provided on the top of the support plate.
[0014] In summary, this utility model has the following beneficial effects:
[0015] 1. The first, second, third, and fourth electric cylinders have a faster response speed compared to traditional crank-connecting rod structures or hydraulic structures. The first, second, third, and fourth electric cylinders, which are set at the four corners of the fixed plate, serve as support plates that can mimic any shaking trajectory and frequency, making them better suited for centrifuges.

[0021] Example 1:
[0022] like Figures 1-2As shown, a vortex mixer includes a shaking table 1 and a centrifuge 2. The centrifuge 2 is fixedly mounted on the top of the shaking table 1. The shaking table 1 includes a fixed plate 11, a first electric cylinder 12, a second electric cylinder 13, a third electric cylinder 14, and a fourth electric cylinder 15. The first electric cylinder 12, the second electric cylinder 13, the third electric cylinder 14, and the fourth electric cylinder 15 are respectively located at the four corners of the top of the fixed plate 11. The top ends of the first electric cylinder 12, the second electric cylinder 13, the third electric cylinder 14, and the fourth electric cylinder 15 are connected to the same support plate 3. The centrifuge 2 is fixedly mounted on the top of the support plate 3. The top and bottom ends of the first electric cylinder 12, the second electric cylinder 13, the third electric cylinder 14, and the fourth electric cylinder 15 are all provided with connecting parts 4. The first electric cylinder 12, the second electric cylinder 13, the third electric cylinder 14, and the fourth electric cylinder 15 are connected to the fixed plate 11 / support plate 3 through the connecting parts 4. The connecting parts 4 are used to allow both ends of the first electric cylinder 12, the second electric cylinder 13, the third electric cylinder 14, and the fourth electric cylinder 15 to rotate freely. The connecting parts 4 include a first bearing 41 and a servo motor 42. The servo motor 42 is located on one side of the first bearing 41. The inner ring end face of the first bearing 41 is provided with an extension, and a first gear is sleeved on the extension. A second gear 43 is fitted onto the output shaft of the servo motor 42, and the first gear and the second gear 43 mesh. A mounting plate 44 is fixedly connected to the inner ring of the first bearing 41. One end of a connecting rod 45 is hinged to the mounting plate 44, and the other end of the connecting rod is connected to one end of the first electric cylinder 12 / second electric cylinder 13 / third electric cylinder 14 / fourth electric cylinder 15. This ensures that both ends of the first electric cylinder 12 / second electric cylinder 13 / third electric cylinder 14 / fourth electric cylinder 15 are hinged and fixed. When simulating shaking, the servo motor drives the inner ring of the first bearing to move in the same direction and at the same angle. Rotation can simulate different swaying paths. By controlling the rotation speed and the cycle of forward and reverse rotation, more swaying patterns can be simulated. When using it, it is necessary to control the servo motors of each connector to rotate at the same speed and in the same direction. In some cases, to increase the degree of freedom of the connectors, a rotating shaft can be set on the four connectors connected to the support plate to make them more free. The bottom four corners of the fixed plate 11 are equipped with equal height pads. The top plate of the fixed plate 11 is equipped with a buffer layer. The top of the fixed plate 11 is equipped with multiple infrared ranging sensors. The top of the support plate 3 is equipped with a vibration detection sensor.
[0023] Specific implementation process: The first electric cylinder 12, the second electric cylinder 13, the third electric cylinder 14 and the fourth electric cylinder 15 have a faster response speed compared to traditional crank connecting rod structures or hydraulic structures. The first electric cylinder, the second electric cylinder, the third electric cylinder and the fourth electric cylinder set at the four corners of the fixed plate are support plates that can imitate any shaking trajectory and frequency, so that they can be better adapted to centrifuges.
