[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the antiemulsification test cup rotating device of this application embodiment includes: an upper cover 10, a turntable 20, a mounting bracket 30, a limiting bearing seat 50, a drive motor 60, a rotating shaft 170, and a limiting nut 40. The upper cover 10 is a plate-shaped structure and is mounted on the rotating housing. The plate surface of the upper cover 10 has a rotating mounting hole. The turntable 20 matches the rotating mounting hole and is rotatably mounted on the rotating mounting hole. The mounting bracket 30 is mounted on the top of the upper cover 10 and extends above the turntable 20. The limiting bearing seat 50 is a hollow annular structure and is mounted on the mounting bracket 30. The drive motor 60 is mounted on the limiting bearing seat 50 and is located in the middle of the rotating mounting hole. The rotating shaft 170 is connected to the output end of the drive motor 60 and is vertically arranged in the shaft length direction. The limiting nut 40 is threaded onto the outside of the rotating shaft 170 and is located inside the limiting bearing seat 50, abutting against the inner ring of the bearing in the limiting bearing seat 50.
[0044] In this specific embodiment, the power of the drive motor 60 can be stably transmitted to the rotating shaft 170 and the turntable 20. Through the cooperation of the limiting bearing seat 50 and the limiting nut 40, the axial movement of the rotating shaft 170 is effectively limited, ensuring the stability of the turntable 20's rotation and providing a reliable rotational basis for the anti-emulsification experiment. Specifically, the limiting bearing seat 50, the limiting bearing, and the limiting nut 40 limit the rotating shaft 170 in the horizontal direction, ensuring that the rotating shaft 170 can only rotate and will not displace in the horizontal direction. When the entire device is in a horizontal and stable state, the reagent tube will not shift laterally during rotation, ensuring the accuracy of the anti-emulsification test results.
[0045] The limiting nut 40 is fitted onto the external threaded connection of the rotating shaft 170, and the outer side of the limiting nut 40 abuts against the inner ring of the limiting bearing in the limiting bearing seat 50, ensuring that the rotating shaft 170 rotates smoothly while preventing the rotating shaft 170 from shifting laterally during rotation.
[0046] In one specific embodiment, the output end of the drive motor 60, the rotating shaft 170, the limit bearing seat 50, and the limit thread are coaxially arranged, which can minimize the eccentric force and vibration during rotation, improve the smoothness of device operation, and reduce wear between components.
[0047] In one specific embodiment, the limiting nut 40 is fixedly connected to the bearing inside the limiting bearing seat 50, ensuring that there is no relative rotation between the limiting nut 40 and the inner ring of the bearing, thereby more reliably limiting the axial position of the rotating shaft 170, ensuring that the power of the drive motor 60 can be fully transmitted to the rotating shaft 170, and avoiding power loss and structural instability caused by relative rotation.
[0048] In this specific embodiment, the upper limit bearing 151 is embedded inside the limit bearing housing 50. The outer ring of the upper limit bearing 151 abuts against the inside of the limit bearing housing 50, and the inner ring abuts against the limit nut 40. The upper limit bearing 151, embedded inside the limit bearing housing 50, with its outer ring abutting against the inside of the limit bearing housing 50 and its inner ring abutting against the limit nut 40, provides support and limitation for the limit nut 40. Specifically, the upper limit bearing 151 increases the axial limiting effect on the rotating shaft 170, better withstands axial loads, and reduces axial movement of the rotating shaft 170 during rotation.
[0049] In one specific embodiment, the device further includes a lower limit bearing 152, which is embedded inside the limit bearing housing 50. The outer ring of the lower limit bearing 152 abuts against the inside of the limit bearing housing 50, and the inner ring abuts against the rotating shaft 170. The cooperation between the upper limit bearing 151 and the lower limit bearing 152 effectively withstands axial forces from both vertical and horizontal directions, ensuring that the rotating shaft 170 maintains a stable axial position during rotation, further enhancing the overall stability and impact resistance of the device.
[0050] The upper limit bearing 151 and the lower limit bearing 152 are arranged vertically, with the upper limit bearing 151 located above the lower limit bearing 152.
[0051] In one specific embodiment, the system further includes: a test tube rack base plate 80 and a turntable connecting column 90. The test tube rack base plate 80 is an annular plate structure, corresponding to the turntable 20. The turntable connecting column 90 is a rod structure, with its upper and lower ends connected to the test tube rack base plate and the turntable 20, respectively. The turntable 20 and the test tube rack base plate are arranged vertically. The surface of the turntable 20 has multiple test tube mounting holes, and the surface of the test tube rack base plate has multiple test tube mounting slots 81, each corresponding to a test tube mounting hole. The test tube rack base plate 80 and the turntable 20 are arranged vertically to support the bottom of the test tubes.
[0052] In this specific embodiment, the setup of the test tube rack base plate 80 and the turntable connecting column 90 provides a stable installation structure for the experimental test tubes. The corresponding design of the test tube mounting holes and mounting slots facilitates the quick and accurate installation of experimental cups, improving the convenience and efficiency of experimental operations, while ensuring the stability of the experimental cups during rotation.
[0053] In one specific embodiment, the system further includes: a ball bearing 160; a circular mounting hole; an annular abutment plate extending towards the center; the ball bearing 160 being mounted on the abutment plate; and a turntable 20 mounted on the ball bearing 160 and rotatably connected to the upper cover 10. By using the ball bearing 160 to rotatably connect the turntable 20 to the upper cover 10, rotational resistance is reduced and jamming is avoided. The ball bearing 160 significantly reduces the frictional resistance between the turntable 20 and the upper cover 10, allowing the turntable 20 to rotate more flexibly and smoothly, reducing the load on the drive motor 60, and also reducing wear during rotation.
[0054] In one specific embodiment, the plate surface of the mounting bracket 30 and the top cover 10 are spaced apart by a preset distance. The reasonable preset distance provides sufficient space for the rotation of the turntable 20 and the installation and operation of other components, avoiding interference between components and making the structure of the device more compact and reasonable.
[0055] In one specific embodiment, the system further includes: motor connecting posts 100, which are rod-shaped structures vertically mounted on the limiting bearing seat 50. Multiple motor connecting posts 100 are arranged at circumferential intervals, and the drive motor 60 is mounted on one of the multiple motor connecting posts 100. The multiple circumferentially spaced motor connecting posts 100 can evenly distribute the weight and force of the drive motor 60, improving the stability of the drive motor 60's installation and avoiding structural deformation or instability caused by single-point force. It also facilitates the installation and disassembly of the drive motor 60. Furthermore, by using the motor connecting posts 100 to create a distance between the motor and the turntable 20, it is easier to observe the rotation of the rotating shaft 170.
[0056] In one specific embodiment, the top cover 10, turntable 20, mounting bracket 30, limit bearing seat 50, drive motor 60, rotating shaft 170 and limit nut 40 are all made of corrosion-resistant metal material, which can adapt to corrosive environments such as anti-emulsification experiments, greatly improving the durability and service life of the device and reducing failures and maintenance costs caused by corrosion.
[0057] In one specific embodiment, it further includes: a zero-position detection photoelectric switch 122, a cup-position detection photoelectric switch 121, a detection toothed plate fixing shaft, a zero-position detection toothed plate 130, and a cup-position detection toothed plate 140. The drive motor 60 is a dual-axis worm gear reducer motor, which includes upper and lower output ends. The detection toothed plate fixing shaft is connected to the upper output end of the drive motor 60, and the rotation direction of the detection toothed plate fixing shaft is the same as the rotation direction of the rotating shaft 170. The zero-position detection toothed plate 130 and the cup-position detection toothed plate 140 are both long strip plate-shaped structures, which are arranged on the detection toothed plate fixing shaft. The axial length direction of the detection toothed plate fixing shaft is perpendicular to the length direction of the zero-position detection toothed plate 130 and the cup-position detection toothed plate 140. The zero-position detection photoelectric switch 122 and the cup position detection photoelectric switch 121 are respectively mounted on the mounting bracket 30. The zero-position detection photoelectric switch 122 corresponds to the zero-position detection toothed plate 130. The zero-position detection toothed plate 130 can rotate circumferentially to the zero-position detection photoelectric switch 122 to obtain information that the rotating shaft 170 has rotated one revolution. The cup position detection toothed plate 140 can rotate circumferentially to the cup position detection photoelectric switch 121 to obtain information that a test tube has rotated to the next position.
[0058] In this specific embodiment, both the zero-position detection photoelectric switch 122 and the cup position detection photoelectric switch 121 are connected to the circuit board or the heavy end to transmit the acquired signals to the computer.
[0059] The number of cup position detection teeth 140 corresponds one-to-one with the number and position of test tube mounting holes.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
