[0003] When testing materials through a spectrometer, the materials are usually placed in a sample cup with a transparent sapphire plate at the bottom. The sample cup is placed on the spectrometer with the infrared detection probe facing the transparent plate at the bottom of the sample cup, so that the material inside can be detected through the transparent plate. In order to improve the detection accuracy, it is generally necessary to move the position of the sample cup to achieve multi-point detection. Currently, the sample cup is moved manually, which is complicated to operate and may cause the position after the move to overlap with the previously detected position. Utility Model Content

[0006] The rotating platform is placed on the spectrometer, and the sample cup is placed in the rotating tube and supported by a ring-shaped support table. After the infrared detection probe of the spectrometer passes through the transparent plate at the bottom of the sample cup to detect the material once, the driving mechanism drives the rotating tube to rotate a certain angle, thereby driving the rotating tube to rotate a certain angle, so as to detect the material at another position, and the above steps are repeated many times to achieve multiple detections.

Since a certain distance is reserved between the driving motor shaft and the rotating tube, the intermediate gear is provided to reduce the diameter of the motor gear.

[0009] As an optimization, a support shield is installed inside the housing. The drive motor is installed inside the support shield. The rotating shaft of the drive motor passes through the support shield and is connected to the motor gear. The intermediate gear shaft is pivotally connected to the support shield. The support shield provided in this solution realizes the installation of the intermediate gear.

The lower end of the rotating tube is rotatably connected to the counterbore of the lower housing through a bearing. In this solution, the upper housing and the lower housing are connected by bolts, realizing the installation of each internal component.

[0011] As an optimization, weights for pressing the material are installed in the sample cup. The weights in this solution realize the pressing of the material and improve the detection accuracy.

[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0023] like Figures 1 - 7 As shown, a spectrometer detection rotating platform of the utility model comprises a hollow shell, wherein the shell comprises a lower shell 1 and an upper shell 2 connected by bolts, so as to facilitate the installation of internal parts.

[0024] The shell has a vertically penetrating mounting hole, and the lower shell 1 and the upper shell 2 have circular holes, and the two circular holes constitute the mounting hole, and a vertical rotating tube 3 is rotatably connected in the mounting hole, and the rotating tube 3 is a circular tube. Figure 4 As shown, the lower end of the rotating tube 3 is rotatably connected to the countersunk hole of the lower shell 1 through a bearing.

[0025] The sample cup 10 is placed in the rotating tube 3, and a weight 11 for pressing the material is installed in the sample cup 10. The sample cup 10 includes a metal round tube and a sapphire plate bonded to the lower end of the round tube. The sapphire plate is a transparent plate. In this embodiment, the wall thickness of the sample cup 10 is equal at all places. The outer diameter of the weight 11 is slightly smaller than the inner diameter of the sample cup 10, so it can be placed in the sample cup 10 to press the material so that the material and the sapphire plate fit tightly.

[0026] The inner wall of the rotating tube 3 is provided with an annular support platform 9 for supporting the sample cup 10. The annular support platform 9 is arranged at the lower end of the rotating tube 3. The height of the annular support platform 9 is 0.3-2mm, so that the bottom of the sample cup and the infrared detection probe maintain a very small distance, which does not affect the detection result and does not wear the infrared detection probe.

[0027] The driving mechanism is also included to drive the rotating tube 3 to rotate. The driving mechanism is installed in the housing, and includes a driving motor 8 fixed in the housing and a gear ring 4 fixed to the outer ring of the rotating tube 3. The gear ring 4 is integrally formed with the rotating tube 3 and is arranged on the outer ring of the upper end of the rotating tube 3.

[0028] The rotating shaft of the driving motor 8 faces upward, and the driving motor 8 is provided with a motor gear 6 for driving the gear ring 4 to rotate. An intermediate gear 5 is connected to the inner shaft of the housing, and the motor gear 6 is connected to the gear ring 4 through the intermediate gear 5.

[0029] like Figure 1 , 3As shown in Fig. 4, in order to implement the setting of the intermediate gear 5, a support shield 7 is installed in the housing. The support shield 7 is a cylindrical shield with a lower opening. The support shield 7 is inserted into the counterbore of the lower housing 1. The drive motor 8 is installed in the support shield 7 and fixed to the top surface of the support shield 7 by bolts. The rotating shaft of the drive motor 8 passes through the support shield 7 and is connected to the motor gear 6.

[0030] The intermediate gear 5 is pivotally connected to the support shield 7 and is located above the support shield.

[0031] The usage method of the present utility model:

[0032] During detection, solid materials are poured into the sample cup 10 and pressed tightly by the weights 11. This rotary platform is placed on the spectrometer 14. When placing, the infrared detection probe is eccentrically arranged with the axis of the sample cup 10. The sample cup 10 is placed in the rotary tube 3. After the spectrometer 14 performs a detection, the drive motor 8 rotates a certain angle, so that the toothed ring 4 is driven to rotate through the motor gear 6 and the intermediate gear 5, thereby driving the rotary tube 3 to rotate a certain angle, so as to detect the materials at another position. The above steps are repeated multiple times to achieve multiple detections.

[0033] Of course, the above description is not limited to the above examples. The technical features not described in the present utility model can be realized by or adopted the existing technology, and will not be elaborated here; the above embodiments and drawings are only used to illustrate the technical solutions of the present utility model and are not limitations to the present utility model.
