Description

Technical Field

[0001] This invention relates to the field of analyzer technology, and in particular to a lutein extraction analyzer. Background Technology

[0002] Lutein is a nutrient that humans can absorb from eating fruits and vegetables, but its absorption and utilization rate is generally low. If you are deficient in lutein, you can take supplements. Elderly people with poor digestion can use sublingual sprays to supplement lutein. Marine microalgae are rich in lutein, but their composition needs to be analyzed.

[0003] A Chinese utility model patent (CN206074526U) discloses a marine microalgae lutein extraction and analysis instrument, comprising an ultrasonic generator, a housing, an automatic sampler, a controller, and a liquid chromatograph. The ultrasonic generator is positioned above the housing, and an ultrasonic transducer is located below it. An ultrasonic vibration rod is mounted inside the transducer, and a cell disruption head is attached to the vibration rod. A sampling tube is located on the lower side of the housing, and a solenoid valve is mounted on the sampling tube. The sampling tube leads to the automatic sampler, which is positioned in the center of a base. The advantages of this lutein extraction and analysis instrument are that it can perform cell disruption, automatic extraction, and detection analysis, simplifying the process, improving analytical efficiency, and being easy to use.

[0004] There are still some problems with the extraction analyzer during use.

[0005] Traditional equipment uses ultrasonic vibration to promote the mixing of pulverized materials and reaction liquid, which has problems such as high energy loss, local overheating that can damage heat-sensitive components, and insufficient mixing uniformity. At the same time, existing devices lack a stable reaction vessel clamping structure, and sampling relies heavily on manual operation, which is cumbersome, has low accuracy, and is prone to errors, making it difficult to meet the needs of efficient, stable, and automated lutein extraction and analysis.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The present invention has a reasonable structure. When the stage moves back and forth to fully mix the solution inside the reaction vessel, the drive motor operates to rotate the transmission rod. The rotation of the transmission rod drives the horizontal plate to rotate. Rollers are provided on the horizontal plate, and the position of the rollers can be adjusted by a turntable. The rotation of the horizontal plate causes the rollers to slide inside the slide rail, which facilitates the movement of the stage by the slide rail through the connecting plate. The movement of the stage causes the pulleys to slide on the slide rod, thereby increasing the stability of the stage movement.

[0019] 2. In this invention, the handle is first pulled down, and then the sliding sleeve slides on the positioning rod to pull the spring. The movement of the sliding sleeve causes the driven plate on the fixed plate to move. The movement of the driven plate causes the arm plate to rotate through the linkage plate. Then the reactor is placed between the limiting plates. When the handle is released, the clamping plate will retract due to the elastic force of the spring. Then the arc groove on the clamping plate will clamp the surface of the reactor for fixation.

[0020] 3. In this invention, the rotating rod is rotated by the operation of the servo motor, which facilitates the movement of the liquid sampling gun on the movable arm to the top position of the reactor. The retraction of the telescopic rod allows the liquid sampling gun to enter the interior of the reactor to sample the solution. Then, the movable arm moves upward to remove the liquid sampling gun from the interior of the reactor. The servo motor operates again to move the liquid sampling gun above the test cup and inject the solution into the test cup for analysis. Attached Figure Description

The shaking component is disposed on the analyzer body 1 for use with a reaction vessel 208, the clamping component is disposed on the shaking component for use with the shaking component, and the sampling component is disposed on the analyzer body 1 for use with the reaction vessel 208.

[0033] Specifically, it should be noted that the drive motor 302 and the servo motor 501 are electrically connected to the control panel 102 via wires. The specific working principles between them are based on existing technologies and will not be elaborated on here. The solution inside the reaction vessel 208 is sampled using the liquid sampling gun 504.

[0034] In one embodiment of this invention, the shaking assembly includes a pair of first supports 2 fixedly mounted on the analyzer body 1. A sliding rod 201 is fixedly connected between the two ends of the pair of first supports 2. A pulley 202 is slidably connected to the sliding rod 201 and rotatably connected to a docking plate 203. A fixing column 204 is fixedly connected to the center of the top surface of the docking plate 203. The top of the fixing column 204 is fixedly connected to a second support 205. The top of the second support 205 is fixedly connected to the bottom surface of a stage 206. A pair of limiting plates 207 are fixedly connected to the top surface of the stage 206. A reaction vessel 208 is disposed between the pair of limiting plates 207. A pair of connecting plates 3 are fixedly connected to the center of the bottom surface of the stage 206. A sliding rod is fixedly connected between the pair of connecting plates 3. A drive motor 302 is fixedly connected to the analyzer body 1 via rail 301. The drive motor 302 is located on the bottom surface of the stage 206. A transmission rod 303 is fixedly connected to the output end of the drive motor 302. A horizontal plate 304 is fixedly connected to the top end of the transmission rod 303. A through groove 305 is provided on the horizontal plate 304. A bearing seat 306 is fixedly connected to the bottom surface of the horizontal plate 304. A threaded rod 307 is rotatably connected to the bearing seat 306. A turntable 308 is fixedly connected to one end of the threaded rod 307. A sleeve block 309 is threadedly connected to the threaded rod 307. A rod body 310 is fixedly connected to the top surface of the sleeve block 309. The rod body 310 extends into the interior of the slide rail 301 through the through groove 305. A roller 311 is rotatably connected to the rod body 310. The roller 311 is slidably connected inside the slide rail 301.

[0035] Specifically, when the stage 206 is moved back and forth to fully mix the solution inside the reactor 208, the drive motor 302 operates to rotate the transmission rod 303. The rotation of the transmission rod 303 drives the horizontal plate 304 to rotate. Rollers 311 are provided on the horizontal plate 304, and the position of the rollers 311 can be adjusted by the turntable 308. The rotation of the horizontal plate 304 causes the rollers 311 to slide inside the slide rail 301, thereby facilitating the movement of the stage 206 through the connecting plate 3. The movement of the stage 206 causes the pulleys 202 to slide on the slide rod 201, thereby increasing the stability of the movement of the stage 206.

[0036] In one embodiment of this invention, the clamping assembly includes a third bracket 4 fixedly connected to one side of the top of the platform 206. Arm plates 401 are rotatably connected to both ends of the third bracket 4. A crossbar 402 is fixedly connected to the other end of the arm plates 401. A clamping plate 403 is fixedly connected to the crossbar 402. An arc-shaped groove 404 is formed on the side of the clamping plate 403 near the reactor 208, and the arc-shaped groove 404 fits against the surface of the reactor 208. A positioning rod 405 is fixedly connected to the platform 206, and a collar is fixedly connected to the top of the positioning rod 405. 406. A sliding sleeve 407 is slidably connected to the positioning rod 405. A spring 408 is sleeved on the positioning rod 405. The two ends of the spring 408 are fixedly connected to the bottom surface of the collar 406 and the top surface of the sliding sleeve 407, respectively. A handle 409 is fixedly connected to the surface of the sliding sleeve 407. A fixing plate 410 is fixedly connected to the side of the surface of the sliding sleeve 407 away from the handle 409. The other end of the fixing plate 410 is fixedly connected to the driven plate 411. A linkage plate 412 is rotatably connected to both ends of the driven plate 411. The other end of the linkage plate 412 is rotatably connected to the arm plate 401.

[0037] Specifically, first, the handle 409 is pulled downwards, then the sliding sleeve 407 slides on the positioning rod 405 to pull the spring 408. The movement of the sliding sleeve 407 drives the driven plate 411 on the fixed plate 410 to move. The movement of the driven plate 411 causes the arm plate 401 to rotate through the linkage plate 412. Then, the reactor 208 is placed between the limiting plates 207. The handle 409 is released, and the clamping plate 403 will retract due to the elastic force of the spring 408. Then, the arc groove 404 on the clamping plate 403 will clamp onto the surface of the reactor 208 for fixation.

[0038] As one embodiment of this invention, the sampling component includes a bracket 5 fixedly mounted on the analyzer body 1. A servo motor 501 is fixedly connected to the bracket 5. A rotating rod 502 is fixedly connected to the output end of the servo motor 501. A movable arm 503 is slidably connected to the rotating rod 502. A liquid sampling gun 504 is fixedly mounted on the other end of the movable arm 503. A telescopic rod 505 is fixedly connected to the bottom surface of the movable arm 503. The bottom end of the telescopic rod 505 is fixedly mounted on a clamping plate 506. One end of the clamping plate 506 is fixedly connected to the rotating rod 502.

[0039] Specifically, the servo motor 501 rotates the rotating rod 502, which in turn moves the sampling gun 504 on the movable arm 503 to the top of the reactor 208. The retraction of the telescopic rod 505 allows the sampling gun 504 to enter the reactor 208 to sample the solution. Then, the movable arm 503 moves upward to remove the sampling gun 504 from the reactor 208. The servo motor 501 then moves the sampling gun 504 above the test cup 106, injecting the solution into the test cup 106 for analysis.

[0040] The working principle of this invention is as follows: When the stage 206 moves back and forth to fully mix the solution inside the reactor 208, the drive motor 302 operates to rotate the transmission rod 303. The rotation of the transmission rod 303 drives the horizontal plate 304 to rotate. Rollers 311 are provided on the horizontal plate 304, and the position of the rollers 311 can be adjusted by the turntable 308. The rotation of the horizontal plate 304 causes the rollers 311 to slide inside the slide rail 301, thereby facilitating the movement of the stage 206 through the connecting plate 3. The movement of the stage 206 causes the rollers 202 to slide on the slide rod 201, thereby increasing the stability of the movement of the stage 206.

[0041] First, pull the handle 409 downwards. Then, the sliding sleeve 407 slides on the positioning rod 405, pulling the spring 408. The movement of the sliding sleeve 407 causes the driven plate 411 on the fixed plate 410 to move. The movement of the driven plate 411 causes the arm plate 401 to rotate through the linkage plate 412. Then, the reactor 208 is placed between the limiting plates 207. Release the handle 409, and the clamping plate 403 will retract due to the elastic force of the spring 408. Then, the arc groove 404 on the clamping plate 403 will clamp onto the surface of the reactor 208 for fixation.

[0042] The servo motor 501 rotates the rotating rod 502, which allows the sampling gun 504 on the movable arm 503 to move to the top of the reactor 208. The retraction of the telescopic rod 505 allows the sampling gun 504 to enter the reactor 208 to sample the solution. Then, the movable arm 503 moves upward to remove the sampling gun 504 from the reactor 208. The servo motor 501 then moves the sampling gun 504 above the test cup 106 to inject the solution into the test cup 106 for analysis.

[0043] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
