Description

Technical Field

[0001] This utility model relates to the field of infrared spectrometer technology, and in particular to a sampling device for infrared spectral testing and analysis. Background Technology

[0002] Infrared spectrometers are instruments that utilize the absorption characteristics of substances to infrared radiation of different wavelengths to analyze molecular structure and chemical composition. An infrared spectrometer typically consists of a light source, monochromator, detector, and computer processing system. Depending on the spectroscopic device, they are classified as dispersive or interferometric. For a dispersive dual-path optical null-balanced infrared spectrophotometer, when a sample absorbs infrared radiation of a certain frequency, the vibrational energy levels of the molecules undergo transitions. The corresponding frequency of light in the transmitted beam is weakened, creating a difference in intensity between the reference and sample light paths, thus obtaining the infrared spectrum of the sample. However, sampling often requires manual sampling or placement, and the process of quickly changing samples for subsequent analysis is not possible, thus reducing the effectiveness of the instrument.

The assembly plate then moves the fixed bracket on the fixed sleeve block and the fixed toothed plate, and the abutting recess on the movable sleeve block, adjusting the distance between the two abutting recesses to a suitable level. Simultaneously, the electric telescopic rod on the abutting recess is activated as needed, moving the abutting block. This allows the two abutting blocks to press the material together for placement or sampling. The moving assembly allows for the movement of the motor, moving rod, and moving... The system utilizes a combination of a moving motor and a moving rod to rotate the moving wheel. Simultaneously, the moving wheel contacts the inner wall of the fixed groove, generating friction. The moving wheel then moves within the fixed groove, causing the movable sleeve on the moving motor to move along the direction of the fixed support. This allows the movable sleeve to adjust the material pressed against the clamping block to a suitable distance, aligning it with or moving it away from the testing platform. The movable components allow the movable support, moving motor, moving rod, and moving gear to work together. The moving motor drives the moving rod and moving gear to rotate, and then the moving gear meshes with its corresponding fixed toothed plate, causing the fixed toothed plate to slide along the inside of the fixed sleeve. The fixed toothed plate then moves the movable sleeve on the fixed support, simultaneously adjusting the material pressed against the clamping plate to a suitable height and allowing for spectral analysis after contact with the testing platform. This eliminates the need for manual sampling or rapid analysis after sample placement, thus improving the overall performance. Attached Figure Description

An movable component for adjusting the movement of the fixed toothed plate 13 is connected to the side wall of the fixed sleeve block 12. The movable component includes two movable brackets 16 fixedly connected to the side wall of the fixed sleeve block 12. A movable motor 17 is fixedly connected to the surface of one of the movable brackets 16. A movable rod 18 is fixedly connected to the output end of the movable motor 17. The end of the movable rod 18 passes through one of the movable brackets 16 and is rotatably connected to the other movable bracket 16. A movable gear 19 is fixedly sleeved on the outer side wall of the movable rod 18. The movable gear 19 meshes with its corresponding fixed toothed plate 13. The movable motor 17 drives the movable rod 18 to rotate.

[0031] A fixing groove is provided on the outer wall of the fixed bracket 15. A movable sleeve block 20 is movably sleeved on the outer wall of the fixed bracket 15. A pressing concave plate 21 is fixedly connected to one side of each of the two movable sleeve blocks 20. A pressing electric telescopic rod 22 is fixedly connected through the top and bottom of the pressing concave plate 21. A pressing block 23 is fixedly connected to the piston end of the pressing electric telescopic rod 22. A moving component is connected to the side wall of the movable sleeve block 20.

The moving motor 24 drives the moving rod 25 to rotate.

[0032] Working principle: In use, first start the adjustment motor 9 on the adjustment bracket 8. The adjustment motor 9 drives the adjustment support plate 10 and the adjustment shaft 11 to rotate. At the same time, the adjustment shaft 11 is slidably installed inside the corresponding adjustment loop 7, which drives the adjustment push plate 5 on the adjustment cross plate 6 to move along the direction on the assembly bracket 3. Then, the adjustment push plate 5 also drives the assembly plate 4 to move along the direction on the assembly bracket 3, so that the two assembly plates 4 are close to each other. Then, the assembly plate 4 also drives the fixed sleeve block 12 and the fixed toothed plate 13 to move. At the same time, the fixed toothed plate 13 also drives the movable sleeve block 20 and the pressing concave plate 21 on the fixed bracket 15 to move, so that the two pressing concave plates 21 are adjusted to a suitable distance and are fitted together to accommodate different specifications of spectral materials.

[0033] Then, activate the electric telescopic rod 22 on the clamping concave plate 21, so that the electric telescopic rod 22 drives the clamping block 23 to move, so that the two clamping blocks 23 clamp the material from top to bottom.

[0034] Next, the moving motor 24 is started, which drives the moving rod 25 and the moving wheel 26 to rotate. At the same time, the moving wheel 26 contacts the inner wall of the fixed groove and generates friction. Then the moving wheel 26 moves in the fixed groove, which also drives the movable sleeve block 20 on the moving motor 24 to move along the direction on the fixed bracket 15. This causes the movable sleeve block 20 to also drive the material pressed on the pressing block 23 to adjust back and forth to a suitable distance and align with the detection table 2.

[0035] Then, the movable motor 17 on the movable bracket 16 is started, which drives the movable rod 18 and the movable gear 19 to rotate. Then, the movable gear 19 meshes with its corresponding fixed tooth plate 13, causing the fixed tooth plate 13 to slide along the inside of the fixed sleeve block 12. Then, the fixed tooth plate 13 also drives the movable sleeve block 20 on the fixed bracket 15 to move. At the same time, the movable sleeve block 20 also drives the material on the pressing concave plate 21 to adjust to a suitable height and contact the detection stage 2, and then undergoes rapid spectral analysis by the infrared spectrometer body 1.

[0036] During sampling, the movable motor 17 is restarted, which drives the movable rod 18 and the movable gear 19 to rotate. Then, the movable gear 19 drives the fixed toothed plate 13 to slide along the inside of the fixed sleeve block 12. Next, the fixed toothed plate 13 also drives the movable sleeve block 20 on the fixed bracket 15 to move and press against the material pressed against the concave plate 21 to adjust to a suitable height and separate from the detection table 2. Then, the moving motor 24 is started, which drives the moving rod 25 and the moving wheel 26 to rotate. At the same time, the moving wheel 26 contacts the inner wall of the fixed groove and generates friction. Then, the moving wheel 26 moves in the fixed groove, which also drives the movable sleeve block 20 on the moving motor 24 to move along the direction on the fixed bracket 15. This allows the movable sleeve block 20 to also adjust the material pressed against the pressing block 23 back and forth to a suitable distance and separate from the detection table 2.

[0037] Then, the electric telescopic rod 22 on the clamping concave plate 21 is activated, causing the electric telescopic rod 22 to drive the clamping block 23 to separate from the material. Next, the adjusting motor 9 is activated, which drives the adjusting support plate 10 and the adjusting shaft 11 to rotate. At the same time, the adjusting shaft 11 is slidably installed inside the corresponding adjusting return hole 7, causing the adjusting push plate 5 on the adjusting cross plate 6 to move along the direction on the assembly bracket 3. Then, the adjusting push plate 5 also drives the assembly plate 4 to move along the direction on the assembly bracket 3, causing the two assembly plates 4 to move away from each other. Then, the assembly plate 4 also drives the fixed bracket 15 on the fixed sleeve block 12 and the fixed tooth plate 13 to move. Then, the fixed bracket 15 also drives the movable sleeve block 20 and the clamping concave plate 21 to move, allowing the two clamping concave plates 21 to be sampled after being separated from the material.
