Description

Technical Field

[0001] This utility model relates to the field of chemical analysis and testing technology, specifically to a shaking mixing device for chemical analysis and testing. Background Technology

[0002] In the prior art, patent CN222324954U discloses a blood oscillation mixing device, including a housing with an oscillation structure and a rotation structure inside. This blood oscillation mixing device, through the oscillation structure, uses a motor to drive a rotating rod. When the cam rotates, if the cam's protrusion is at the top, the roller moves upward, causing the moving plate to move upward via a connecting rod, and the spring contracts. If the cam's protrusion is at the bottom, the spring's deformation force causes the moving plate to move downward via a hinge seat. The cam continues to rotate, causing the blood sample at the top of the moving plate to oscillate up and down, facilitating automated oscillation and improving work efficiency. Furthermore, by incorporating the rotation structure, test tubes containing blood samples are placed inside. A tube stopper is inserted into the top of the test tube, and several test tubes are placed into a fixed hole. An electric turntable rotates these test tubes, facilitating simultaneous centrifugal oscillation of multiple blood samples.

[0003] In actual use, although the device can thoroughly mix the reagents in the test tube by oscillating in the up-down direction and rotating in the horizontal direction, the existing mixing method cannot rotate in the up-down direction, which easily leads to the reagents in the test tube separating into layers after oscillation and mixing. Utility Model Content

[0004] The purpose of this invention is to provide a shaking mixing device for chemical analysis and testing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shaking mixing device for chemical analysis and testing, which is mounted on a workbench. The mixing device includes: a shaking mixing chamber mounted on the workbench, the mixing device being used to mix the materials in the shaking mixing chamber, and further includes:

[0006] An oscillation unit, connected to the oscillation mixing box and mounted on the worktable, is used to drive the oscillation mixing box to move repeatedly.

[0007] A rotating unit is disposed on the worktable and connected to the oscillating mixing box, which is used to drive the oscillating mixing box to rotate and mix the materials in the oscillating mixing box.

[0008] Preferably, the oscillation unit includes:

[0009] A U-shaped frame is provided on the workbench, a first servo motor is connected to the U-shaped frame, a drive shaft is connected to the output end of the first servo motor, and an adapter plate is connected to one end of the drive shaft;

[0010] Both ends of the adapter plate are connected to connecting plates, and all the connecting plates are connected to a movable rod at their connecting ends, with a slider connected to the movable rod.

[0011] The first servo motor is used to drive the drive shaft to rotate the adapter plate, and the adapter plate drives the connecting plate to drive the slider to move laterally;

[0012] The slider is used to drive the oscillating mixing box to move.

[0013] Preferably, the worktable has two sliding holes, and the slider is disposed in the sliding holes;

[0014] The inner shape of the sliding hole matches the shape of the slider, and the sliding hole is used to limit and support the slider.

[0015] Preferably, the adapter plate and all the connecting plates are connected by the movable rod, so that the connecting plates can be adapted to the rotation of the adapter plate.

[0016] Preferably, the rotating unit includes a vertical plate disposed on the slider; a second servo motor is connected to one side of the vertical plate;

[0017] A turntable is connected to the center of the upright plate;

[0018] The second servo motor is connected to an adapter shaft, one end of which is connected to the turntable;

[0019] A connecting rod is connected to the turntable, and a retaining frame is connected to the connecting rod. The retaining frame is used to fix the vibrating mixing tank.

[0020] Preferably, the upright plate has a connecting groove for engaging the turntable.

[0021] Preferably, a limiting ring is also provided in the connecting groove;

[0022] The turntable is provided with a limiting groove on its outer side;

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: This oscillating mixing device for chemical analysis and testing addresses the problem of reagent separation after oscillation caused by the lack of vertical rotation function in existing mixing devices for chemical analysis and testing. By setting up a oscillating unit and a rotating unit working in tandem on the worktable, the above-mentioned drawbacks are effectively solved. In the oscillating unit, the first servo motor fixed by the U-shaped frame drives the slider to move laterally and repeatedly within the sliding hole of the worktable through the drive shaft, adapter plate, connecting plate, and movable rod. The sliding hole provides stable limiting and support for the slider, ensuring the stability of the lateral oscillation of the mixing box. The rotating unit uses the vertical plate on the slider to support the second servo motor, which drives the turntable to rotate through the adapter shaft. The limiting groove on the outside of the turntable precisely matches the limiting ring in the connecting groove of the vertical plate, ensuring the stability of the rotation process. The turntable is fixed to the shaking mixing chamber by a connecting rod and a clamping frame. The friction buffer pad inside the clamping frame stabilizes the chamber and prevents damage. The motor frame on the outside of the upright plate further secures the second servo motor to ensure reliable operation. The combination of lateral oscillation and rotational motion not only completely breaks the stratification phenomenon after reagent mixing, but also significantly improves the mixing uniformity and efficiency. The overall structure is reasonably designed and operates stably, providing a more reliable guarantee for material mixing in chemical analysis and testing. By working in concert with the oscillation unit, the problem of easy stratification after reagent mixing in existing devices is solved on the one hand, and the mixing uniformity and efficiency of materials are significantly improved on the other hand. At the same time, the overall structure is stable, and the friction buffer pad inside the clamping frame protects the shaking mixing chamber, ensuring reliable operation and providing a stable and efficient mixing guarantee for chemical analysis and testing.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-4 This utility model provides a technical solution: a shaking mixing device for chemical analysis and testing, which is mounted on a workbench 1. The mixing device includes: a shaking mixing chamber 2 mounted on the workbench 1, the mixing device being used to mix within the shaking mixing chamber 2, and further includes:

[0035] An oscillation unit, connected to the oscillation mixing box 2, is mounted on the worktable 1. It drives the oscillation mixing box 2 to move repeatedly. Compared to the problems mentioned in the background art, a new lateral repetitive driving oscillation method is added, effectively enhancing the mixing effect of the oscillation mixing box 2 and thus improving its mixing efficiency. A U-shaped frame 46 is mounted on the worktable 1 to fix the first servo motor 47, ensuring its stable connection to the bottom of the worktable 1. The first servo motor 47 is connected to the U-shaped frame 46. Motor 47 drives adapter plate 43 to rotate. Adapter plate 43 drives two connecting plates 44 to rotate, thereby causing two sliders 41 to move laterally, which in turn causes the vibrating mixing box 2 to move laterally repeatedly. A drive shaft 42 is connected to the output end of the first servo motor 47. The drive shaft 42 drives the first servo motor 47 to rotate the adapter plate 43. One end of the drive shaft 42 is connected to the adapter plate 43. Both ends of the adapter plate 43 are connected to connecting plates 44. When the adapter plate 43 rotates, if the adapter plate 43 and the sliders 41 are perpendicular, then... The connecting plate 44 pulls the slider 41 back towards the center of the first servo motor 47. When the adapter plate 43 remains parallel to the slider 41, it pushes the slider 41 out. When the adapter plate 43 rotates continuously via the first servo motor 47, it drives the slider 41 to perform repeated push-pull movements. All the connecting ends of the connecting plates 44 are connected to movable rods 45. The movable rods 45 are used to adapt the connection between the adapter plate 43 and the connecting plate 44, as well as the connection between the connecting plate 44 and the slider 41, and to adapt to rotation. The slider 41 is connected to the movable rod 45; the first servo motor 47 uses... The drive shaft 42 drives the adapter plate 43 to rotate, and the adapter plate 43 drives the connecting plate 44 to drive the slider 41 to move laterally. The slider 41 is used to drive the vibration mixing box 2 to move. Two sliding holes 4 are opened on the worktable 1, and the slider 41 is placed in the sliding holes 4. The inner shape of the sliding hole 4 matches the shape of the slider 41, which not only achieves the effect of limiting, but also supports the slider 41. The sliding hole 4 is used to limit and support the slider 41. The adapter plate 43 and all the connecting plates 44 are connected by a movable rod 45 so that the connecting plate 44 can adapt to the rotation of the adapter plate 43.

[0036] The U-shaped frame 46 fixed on the workbench 1 stably fixes the first servo motor 47. After starting, the first servo motor 47 drives the drive shaft 42 to rotate. The drive shaft 42 drives the adapter plate 43 to rotate synchronously. The connecting plates 44 connected to both ends of the adapter plate 43 are adapted to the slider 41 through the movable rod 45. As the adapter plate 43 continues to rotate, it will drive the slider 41 to move laterally repeatedly in the sliding hole 4 of the workbench 1 through the connecting plate 44 and the movable rod 45. The sliding hole 4 plays a role in limiting and supporting the slider 41. The movement of the slider 41 then drives the associated oscillating mixing box 2 to move laterally repeatedly, realizing the oscillation unit to drive the oscillating mixing box 2 laterally repeatedly, and finally enhancing the mixing effect of the material in the oscillating mixing box 2.

[0037] A rotating unit, mounted on the worktable 1 and connected to the vibrating mixing chamber 2, drives the vibrating mixing chamber 2 to rotate and mix the materials. The rotating unit includes a vertical plate 3 mounted on a slider 41. The vertical plate 3 supports the remaining structure of the rotating unit and can also move laterally under the influence of the slider 41. A second servo motor 51 is connected to one side of the vertical plate 3. The second servo motor 51 drives a turntable 31 to rotate via a connecting shaft 52, thereby rotating the vibrating mixing chamber 2. A turntable 31 is connected to the center of the vertical plate 3, and the turntable 31 is adapted to rotate within the vertical plate 3. A connecting shaft 52 is connected to the second servo motor 51, with one end of the connecting shaft 52 connected to the turntable 31. The turntable 31 is connected to a connecting rod 32, and a retaining frame 33 is connected to the connecting rod 32. The retaining frame 33 is used to fix the vibrating mixing box 2. A connecting groove is opened in the upright plate 3, which is used to clamp the turntable 31. A limit ring 35 is also opened in the connecting groove. A limit groove 34 is provided on the outer side of the turntable 31. The size and shape of the limit groove 34 and the limit ring 35 are matched. There are two upright plates 3 and two sliders 41. A friction buffer pad 36 is provided on the inner side of the retaining frame 33, which is used to protect the friction buffer pad 36 and the vibrating mixing box 2. A motor frame 5 is provided on the outer side of the upright plate 3. The motor frame 5 is connected to the second servo motor 51, which is used to fix the second servo motor 51.

[0038] The vertical plate 3 mounted on the slider 41 can not only be moved laterally by the slider 41, but also supports the rest of the rotating unit structure. The motor frame 5 on the outside of the vertical plate 3 fixes the second servo motor 51. After starting, the second servo motor 51 drives the turntable 31 to rotate through the adapter shaft 52. The turntable 31 is adapted and connected in the connecting groove of the vertical plate 3. The limiting groove 34 on its outside matches the size and shape of the limiting ring 35 in the connecting groove to ensure the stable rotation of the turntable 31. The turntable 31 is connected to the frame 33 through the connecting rod 32. The friction buffer pad 36 on the inside of the frame 33 fixes and protects the vibrating mixing box 2. Finally, driven by the turntable 31, the vibrating mixing box 2 rotates accordingly to achieve the mixing of the materials inside.

[0039] When the shaking mixing device for chemical analysis and testing is in use, the U-shaped frame 46 on the workbench 1 fixes the first servo motor 47. After starting, the first servo motor 47 drives the drive shaft 42 to rotate, which in turn drives the adapter plate 43 to rotate. The adapter plate 43, through the connecting plate 44 and the movable rod 45, drives the slider 41 to move laterally repeatedly within the sliding hole 4 of the workbench 1. The sliding hole 4 provides limitation and support for the slider 41. At the same time, the vertical plate 3 on the slider 41 moves laterally with the slider 41, and the motor frame 5 on the outside of the vertical plate 3 fixes the second servo motor. The second servo motor 51 drives the turntable 31 to rotate via the adapter shaft 52. The turntable 31 rotates within the connecting groove of the vertical plate 3. The limiting groove 34 on its outer side matches the limiting ring 35 in the connecting groove to ensure stable rotation. The turntable 31 is connected to the frame 33 via the connecting rod 32. The friction buffer pad 36 on the inner side of the frame 33 fixes the oscillating mixing box 2. Finally, the oscillating mixing box 2 moves repeatedly laterally under the drive of the slider 41, and rotates under the drive of the turntable 31 to achieve efficient mixing of the internal materials.
