[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1-7As shown, a portable near-infrared spectrometer for detecting cigarette popping beads and cigarette filter rods includes a rotating cup 1, a rotating table 2, a bearing assembly, a gear assembly, a sapphire window 9, a motor 10, a spectral core 11, an instrument base plate 14, a wiring panel 15, an instrument back cover 16, a control system panel 17, and an instrument upper cover 18.

[0033] The box structure consists of an instrument base plate 14, an instrument rear cover 16, and an instrument cover 18. The lower surface of the instrument base plate is flat and can be placed stably on a table. The instrument cover is attached to the instrument base plate. The instrument rear cover is located at the rear opening of the instrument cover. The control system panel is located at the front opening of the instrument cover. The rotating table is located at the upper opening of the instrument cover. The rotating cup is located on the rotating table. The lower end of the rotating table is connected to a bearing assembly and a gear assembly. The rotating table is rotatably mounted on the bearing assembly. The rotating table, bearing assembly, and gear assembly are all provided with through-holes. A sapphire window 9 is located at the lower end of the gear assembly. The spectral core 11 is fixed below the sapphire window.

[0034] Specifically, the bearing assembly of this embodiment includes a bearing 3, a bearing support 4, a bearing retaining ring 5 and a bearing box 6. The rotating table passes through the bearing, the bearing support and the bearing retaining ring in sequence, and the bearing box arranged under the bearing retaining ring is fixed to the bearing support.

[0035] A gear assembly is provided on the lower side of the bearing assembly. The gear assembly includes a gear 7 and a gear retaining ring 8. The sapphire window is fixed to the gear retaining ring. The gear is engaged with the motor gear to control the gear through the motor, thereby enabling the rotary table to rotate. Figure 3 As shown, preferably, the inner ring diameter of the gear in this embodiment is φ80mm, the outer ring diameter is φ100mm, and the thickness is 7mm, wherein a gear protrusion with a diameter of φ87mm and a thickness of 2mm is provided on the upper side of the gear, which is fixed to the bearing retaining ring through the gear protrusion.

[0036] Furthermore, the turntable is constructed of metal, and the sapphire window is 20mm in diameter, chosen for its exceptionally high surface hardness, high thermal conductivity, high dielectric constant, and resistance to chemical acids and alkalis. Its hardness is second only to diamond, and its structural strength is exceptionally high. Therefore, thanks to its enhanced transmittance, the sapphire window is thinner than typical high-dielectric windows, making it ideal for demanding laser systems. Preferably, the turntable is a hollow cylindrical structure with an annular flange on the outside for engaging the instrument cover.

[0037] Furthermore, the diameter of the rotating table can be reduced from top to bottom, and the rotating cup can be fixed by radially reducing it. Figure 3As shown, a groove plug-in portion can also be provided at the bottom of the rotating cup, and the groove plug-in portion can be plugged into the rotating table so that the rotating cup can be set on the rotating table. Of course, the rotating cup of the present invention can be set on the rotating table in other ways.

[0038] The portable near-infrared spectrometer of the present invention is also provided with a battery 13 in the box-shaped structure, which is used to power the motor, the spectral core, and the control system panel. The back cover of the instrument is provided with an opening for installing an exhaust fan 12, which is provided on the portable near-infrared spectrometer through the opening to dissipate heat from the portable near-infrared spectrometer. Figure 4 As shown, a wiring panel can also be installed on the instrument's rear cover. The power cord connects to the motor through two circular openings in the wiring panel. The motor is fixed to a motor mounting plate, which is then mounted on the instrument's base plate. The spectral core is also fixed to the instrument's base plate and controlled by the motor mounted on the base plate. Preferably, the spectral core of the present invention utilizes a spectral structure equipped with a VIAVI spectrometer or a Ti spectrometer, which works in conjunction with a rotating stage to scan cigarette bead and filter rod samples.

[0039] Example 2

[0040] In addition, the present invention also provides a portable near-infrared spectrometer system, which is arranged in a closed box body composed of an instrument upper cover, an instrument back cover and an instrument bottom plate in Example 1, and includes an Android system, a power control module, a sensor communication module, a result physical output module and a sensor control module. The power control module is respectively connected to the Android system, the sensor communication module, the result physical output module and the sensor control module, and is used to control the power on and off status of the near-infrared spectrometer system; the sensor communication module is communicatively connected to the sensor control module and the result physical output module, and controls the sensor control module through the sensor communication module to detect cigarette beads and filter rods, and transmits the detection results to the result physical output module for display.

[0041] The power control module is powered by a 16.8V external power supply, and the power control module is connected to the Android system power supply. The Android system is connected to the sensor communication module and the sensor control module through the serial port.

[0042] When measuring a sample, the sample to be tested is placed in the rotating cup, the rotating cup 1 is placed on the rotating table 2, the power is turned on, and the power indicator light is on. The Android system software sends instructions to the motor to control the rotation of the rotating table, and at the same time activates the spectrum core scanning function to scan the sample spectrum. During the sample measurement process, the spectrum core 11 emits a light source, which shines through the sapphire window 9 and the rotating cup 1 onto the sample to be tested. The reflected light passes through the rotating cup 1 and the sapphire window 9 in turn and is received by the spectrum core 11. After obtaining the spectrum, the spectrum data is substituted into the model for calculation to obtain the test result. After being processed by the power control module, sensor communication module, result physical output module, sensor control module, etc., the test result is directly displayed on the control system panel 17. After scanning the sample, the percentage of the epidermal moisture content of the cigarette beads and the triacetin content of the cigarette filter rod in mg / stick will be directly given on the control system panel.

[0043] This invention effectively measures the concentration of tobacco pellets and filter rods. A portable near-infrared spectrometer equipped with a Viavi or Ti spectral core and a rotating stage scans these pellets and filter rods. After scanning the sample, the device displays the results (% surface moisture content of the pellets and mg triacetin content of the filter rods).

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
