Description

Technical Field

[0001] This invention belongs to the field of tobacco flavoring similarity detection technology, specifically relating to a fully automatic detection device and method for the quality consistency of powdered tobacco flavoring. Background Technology

[0002] Flavorings and fragrances are core technical elements of cigarette products, crucial raw materials for maintaining stable characteristic flavors and preserving the authentic flavor of low-tar cigarettes, playing an irreplaceable role in the tobacco industry's "tar reduction and harm reduction" technology system. Flavorings and fragrances are mostly complex liquid mixtures obtained by blending various natural and synthetic flavorings, containing a large number of volatile and semi-volatile components. Affected by multiple factors such as differences in the origin of flavoring raw materials, batch fluctuations, production and blending processes, and storage conditions, the physicochemical indicators, component contents, and solvent ratios of different batches of powdered flavorings are prone to deviation, directly causing fluctuations in the sensory quality of finished cigarettes. Therefore, conducting rapid and reliable quality consistency testing on incoming or different production batches of powdered flavorings is an essential part of the cigarette production quality control process.

[0003] Currently, the tobacco industry mainly uses two types of methods to evaluate the consistency of quality and similarity of components in powdered tobacco flavorings: chromatographic detection and rapid spectroscopic detection. Existing detection schemes all have obvious technical defects and are difficult to meet the actual needs of large-scale automated industrial testing.

[0004] GC MS (Gas Chromatography) Mass spectrometry (GC-MS) is a classic detection method for analyzing flavoring and fragrance components in the tobacco industry. This method offers high sensitivity and provides detailed qualitative and quantitative information on sample components. Existing patent document CN116756581A discloses a method, apparatus, device, and storage medium for evaluating the similarity of tobacco flavorings and fragrances, using GC-MS. MS can achieve consistency detection of fragrances and flavors, but this method has significant shortcomings: First, it requires complex pretreatment before sample testing, resulting in a long testing cycle, with a single sample taking more than 1 hour to test; Second, the entire testing process, from sample pretreatment to injection analysis, is highly dependent on manual operation, making it unsuitable for screening large batches of samples; Third, the pretreatment stage consumes a large amount of toxic and harmful organic solvents, leading to high reagent costs and issues such as waste disposal and experimental safety, making it difficult to meet the needs of large-scale, rapid, and green testing and control in industrial settings.

[0005] Near-infrared spectroscopy is a rapidly developing technology for detecting flavorings and fragrances in recent years. This method requires no complex pretreatment and has the potential for rapid detection. Existing patent document CN103091282A discloses a method for detecting the quality of tobacco flavorings and fragrances, utilizing near-infrared spectroscopy for rapid detection. However, it still has several limitations in practical applications involving powdered tobacco flavorings: First, existing near-infrared detection devices lack automation; sample addition, spectral acquisition, and detection window cleaning all require manual operation, making continuous, high-throughput detection impossible. Second, near-infrared spectroscopy involves overtone and combination absorption, resulting in weak molecular absorption signals, severe spectral overlap, and significant difficulty in spectral interpretation. Third, powdered tobacco flavorings are mostly dark-colored viscous liquids of varying shades; fluctuations in sample color can cause severe spectral distortion in the near-infrared short-wave region. This distortion can mask the spectral differences of the flavoring components themselves, directly interfering with similarity determination results and exhibiting poor anti-interference capability.

[0006] Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR) FTIR (Fully Fiber Resonance Imaging) is a mid-infrared detection technology that relies on the fundamental frequency vibration signal of molecules to obtain the spectral information of the sample. It requires a small sample volume, does not require complex pretreatment, and can avoid spectral interference caused by sample color, making it suitable for the detection of viscous liquid samples. However, currently, there is no fully automated high-throughput ATR system in the industry suitable for powdered tobacco flavorings. FTIR detection scheme.

[0007] In summary, existing tobacco flavoring quality consistency testing devices suffer from cumbersome pretreatment, long testing cycles, and low automation, failing to simultaneously meet the multiple practical industrial demands for high throughput, automation, environmental friendliness, and stable and reliable test results. Therefore, there is an urgent need to develop a device capable of fully automated continuous testing of powdered tobacco flavorings to overcome the shortcomings of the existing technologies. Summary of the Invention

[0008] The problem that this invention aims to solve is that currently used powdered tobacco flavoring detection devices are difficult to meet the industrial technical requirements of automation and high throughput.

[0009] The present invention solves the above-mentioned technical problems through the following technical means: An automated testing device for the quality consistency of powdered tobacco flavoring includes a frame, a testing unit, a lifting and rotating clamping unit, a powder releasing and pressing unit, and a negative pressure waste suction and reset unit mounted on the frame. The detection unit includes a spectrometer equipped with a detection crystal, and the center of the upper surface of the detection crystal is the detection station; The lifting and rotating clamping unit includes a Z-axis slide and an upper rotating gripper mounted on the output end of the Z-axis slide. The powder release and pressing unit includes a pressing module, a storage bottle fixing plate, and a slide assembly. The slide assembly drives the storage bottle fixing plate to move horizontally, so that the bottle mouth of the solid fragrance storage bottle is vertically aligned with the detection station. The upper rotating jaw holds the knob of the solid fragrance storage bottle and rotates it to release the powder fragrance inside the bottle. The pressing module is used to apply downward pressing force to the powder fragrance that falls on the surface of the detection crystal. The negative pressure waste suction and reset unit is used to remove residual powder from the surface of the detection crystal.

[0010] This device integrates multiple units working together, relying on the upper rotating gripper to achieve clamping and transfer of various tooling, and fully automates the entire process of powdered flavoring sample loading, compaction, spectral acquisition, and crystal negative pressure cleaning, reducing manual intervention, effectively avoiding errors caused by human operation, and meeting the needs of batch automated testing of powdered tobacco flavorings.

[0011] Preferably, the storage bottle fixing plate has a recess, and the shape of the recess is consistent with the bottom of the storage bottle.

[0012] Preferably, the slide assembly is a two-dimensional translational slide, which drives the bottle storage fixing plate to move in the X direction. The Y-plane movement allows for switching the position of the solid fragrance storage bottle between the storage station and the testing station.

[0013] Preferably, the clamping module is an independent clamping fixture, and the downward clamping force of the clamping module is provided by the Z-axis slide table in conjunction with the rotating jaws.

[0014] Preferably, the negative pressure waste suction and reset unit includes a powder suction pipe, a powder suction pipe fixing seat, an external negative pressure material suction assembly, and a powder suction pipe placement frame. The powder suction pipe is fixedly assembled on the powder suction pipe fixing seat, and the rear end of the powder suction pipe is connected to the external negative pressure material suction assembly. The powder suction pipe fixing seat is provided with an upper cylindrical end that can be clamped by an upper rotating gripper. The powder suction pipe placement frame is fixed on the frame and is used to place the powder suction pipe fixing seat.

[0015] Preferably, when the external negative pressure suction assembly is working, the powder suction tube opening is close to the surface of the detection crystal, and the residual powder fragrance on the crystal surface is completely removed by the negative pressure suction, thereby cleaning the detection crystal.

[0016] Preferably, the solid flavor supply unit includes a solid flavor storage rack and a solid flavor storage bottle mounted on a frame. The solid flavor storage bottle includes an upper cavity, a lower cavity, a stirring rod, and a knob. The knob is mounted on the top of the solid flavor storage bottle and is linked to the stirring rod via a spring. The lower part of the stirring rod includes a notch. The bottom of the stirring rod is movably sealed to the lower cavity. Pressing the knob activates the spring, causing the stirring rod to extend out of the lower cavity. Rotating the knob causes the stirring rod to rotate, and the notch carries the powder, thus releasing the powdered flavoring from the bottle.

[0017] The solid flavoring storage bottle adopts a knob-linked stirring rod structure. By rotating the knob, the stirring rod can be driven to stir the powder in the bottle, which can effectively prevent the powdered flavoring from bridging, clumping and blocking, and ensure stable and uniform release of the powdered flavoring.

[0018] Preferably, the solid flavoring storage bottle further includes a guide ring, which is disposed at the mouth of the storage bottle to restrict the movement direction of the stirring rod.

[0019] A guide ring is installed at the bottle mouth to limit and guide the movement of the stirring rod, constrain its movement trajectory, prevent it from swaying and hitting the inner wall of the bottle, and improve the operational stability of the powder feeding mechanism.

[0020] Preferably, the solid fragrance storage bottle also includes a plug, which is located on the side of the bottle's outlet. The plug is detachable and communicates with the inside of the storage bottle.

[0021] The discharge port is equipped with a removable plug, which can control the opening and closing of the discharge port. During sample transfer and storage, the discharge port is sealed to prevent powder leakage. At the same time, the plug is removable, which facilitates cleaning and maintenance of the inside of the storage bottle.

[0022] This invention also discloses a method for using a fully automated detection device for the quality consistency of powdered tobacco flavorings, comprising the following steps: S1. The upper rotating gripper picks up the solid fragrance storage bottle on the solid fragrance storage rack and transfers it to the storage bottle fixing plate. S2. The slide assembly drives the storage bottle fixing plate to move, so that the bottle mouth of the solid fragrance storage bottle is vertically aligned with the detection station. S3. Rotate and press the knob of the upper rotating jaw holding the storage bottle to release the powdered fragrance onto the surface of the detection crystal; S4. The upper rotating gripper picks up the pressing module and moves it to the inspection station to press the powdered fragrance. S5. The spectrometer collects the infrared spectral signal of the compressed powdered fragrance to complete the quality consistency test; S6. The upper rotating gripper returns the clamping module to its original position, then clamps the powder suction tube and moves it to the testing station; S7. Activate the external negative pressure suction assembly to remove residual powder from the surface of the detection crystal through the powder suction tube; S8. Return the powder suction tube to its original position and determine if there is a next sample to be tested. If there is, return to S1; otherwise, end the test.

[0023] The advantages of this invention are: (1) Fully automated high-throughput detection: This device will integrate ATR The combination of FTIR spectroscopy detection and automation mechanism automatically completes the entire process of powder fragrance sample transfer, powder release, sample compaction, spectral acquisition, and crystal residue cleaning. No manual intervention is required for sample addition and cleaning operations, eliminating the need for complex chemical pretreatment. Single sample detection is quick and can achieve uninterrupted continuous detection of multiple batches of samples, making it suitable for rapid screening of large-scale industrial fragrances. (2) Powder feeding is stable and reliable, avoiding the problem of clogging and spillage: This application is equipped with a special solid fragrance storage bottle, and the powder is stirred by the knob linkage stirring rod, which effectively improves the phenomenon of powder bridging, clumping and clogging; with the guide ring constraining the movement trajectory of the stirring rod, rotating the squeezing knob and stirring rod can make the powder fall evenly to the detection crystal station, and can also prevent the powder from spilling during the storage and transportation stage, thus improving the stability of sample loading. (3) Negative pressure cleaning is thorough and cross-contamination of samples is suppressed: The residual powder on the surface of the ATR detection crystal is removed by negative pressure suction. The residual fragrance powder on the crystal surface is directly removed by the suction tube. No cleaning solution or wiping consumables are required. The detection station can be cleaned efficiently, eliminating the interference of the powder residue of the previous sample on the subsequent detection, ensuring that the continuous detection conditions of multiple samples are consistent, and improving the repeatability and accuracy of the spectral detection results. (4) Convenient operation and maintenance of equipment: The same set of lifting and rotating clamping units can be reused to complete the transfer of storage bottles, the turning and squeezing of knobs, the pressing module, and the picking and placing of powder tubes. There is no need to configure a separate drive module for each execution component, which reduces the hardware cost of the equipment. The solid fragrance storage rack is detachable as a whole, and batch sample filling can be completed externally. The tooling parts are easy to disassemble and maintain, the equipment has a low threshold for practical operation, and it is easy to promote and use in industrial sites. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: This invention relates to a fully automated detection device for the quality consistency of powdered tobacco flavorings, see reference. Figure 1 This fully automatic testing device for the consistency of powdered tobacco flavoring quality includes a frame, and a testing unit 1, a lifting and rotating clamping unit 2, a solid flavoring supply unit 3, a negative pressure waste suction and reset unit 4, and a powder release and pressing unit 5, all mounted on the frame.

[0028] For details, please refer to Figures 3-8The lifting and rotating clamping unit 2 includes a Z-axis slide 21, an X-axis slide 22, a Y-axis slide 23, and an upper rotating gripper 24. The three-dimensional spatial movement of the upper rotating gripper is achieved by the three-axis slides, and the gripping and rotating actions are output from the upper rotating gripper. The solid flavor supply unit 3 includes a solid flavor storage rack 31 and a solid flavor storage bottle 32. The solid flavor storage bottle 32 is further divided into an upper cavity 321, a lower cavity 322, a knob 323, a stirring rod 324, a guide ring 325, and a plug 326, used to store the powdered flavor to be tested and achieve controllable feeding. The negative pressure waste suction and recovery system... Unit 4 includes a powder suction tube 41, a powder suction tube fixing seat 42, and a powder suction tube placement rack 43, which, in conjunction with an external negative pressure source, completes the suction and cleaning of residual powder on the surface of the detection crystal. Unit 5 includes a powder release and compaction module 51, a storage bottle fixing plate 52, and a sliding stage assembly 53. The storage bottle fixing plate 52 is used to temporarily place the solid fragrance storage bottle 32, and the sliding stage assembly 53 drives the planar displacement of the storage bottle fixing plate 52. The compaction module 51 compacts the powder sample falling to the detection station. The detection unit is equipped with a spectrometer and a detection crystal, forming a detection station for infrared spectral acquisition of the powder fragrance sample. All units cooperate to automatically complete the entire process of powder fragrance transfer, feeding, compaction, spectral detection, and crystal cleaning.

[0029] For details, please refer to Figure 1 and Figure 2 The detection unit 1 is fixedly mounted on the frame and is the core component for spectral detection in this device. The detection unit 1 includes an ATR. The device includes a Fourier Transform Infrared Spectrometer (FTIR) and an ATR detection crystal. The ATR detection crystal is located at the top of detection unit 1, and its upper surface center forms the detection station. This station is the common working position for the powder release and compaction unit 5 (adding flavoring samples and compacting flavorings) and the negative pressure waste absorption and reset unit 4 (cleaning powder). Detection unit 1 is used to collect the mid-infrared spectral signal of the powdered tobacco flavoring on the upper surface of the ATR detection crystal. It obtains the spectral information of the sample by relying on the fundamental frequency vibration characteristics of molecules, thereby completing the spectral acquisition of the powdered tobacco flavoring and providing raw spectral data for flavoring quality consistency and similarity discrimination.

[0030] See Figure 3The lifting and rotating clamping unit 2 is the core motion actuator of this device. It is fixedly assembled on the upper frame of the machine frame and includes a Z-axis slide 21, an X-axis slide 22, a Y-axis slide 23, and an upper rotating gripper 24. The Y-axis slide 23 is fixedly installed on the crossbeam of the machine frame and serves as the horizontal motion reference for the bottom layer. The X-axis slide 22 is slidably assembled on the slider output end of the Y-axis slide 23 and can follow the Y-axis slide 23 to complete the reciprocating motion in the Y direction. The Z-axis slide 21 is vertically fixed on the moving slider of the X-axis slide 22 and moves horizontally in the X direction with the X-axis slide 22. The upper rotating gripper 24 is rigidly fixedly installed on the lower output slider of the Z-axis slide 21 and moves vertically up and down with the Z-axis slide 21.

[0031] The X-axis slide 22 and Y-axis slide 23 form an XY two-dimensional horizontal motion pair. They receive commands from the main control system to achieve precise coordinated interpolation motion, driving the Z-axis slide 21 and the upper rotary gripper 24 to complete horizontal displacement at any point within the machine's working plane. This enables the upper rotary gripper 24 to quickly and accurately switch positions between various workstations: the solid fragrance supply unit 3, the powder release and pressing unit 5, the negative pressure waste suction and reset unit 4, and the detection unit 1. The Z-axis slide 21 is responsible for outputting vertical feed motion. It can drive the upper rotary gripper 24 downwards to clamp and press the workpiece, or it can drive the upper rotary gripper 24 upwards to lift and release the workpiece. It can flexibly adjust the downward depth and lifting height according to different working conditions, achieving closed-loop control of the vertical position.

[0032] See Figures 4-8 The upper rotating gripper 24 integrates the dual functions of a clamping actuator and a rotating drive mechanism. The clamping mechanism can realize the opening and closing clamping and releasing actions, while the rotating drive mechanism can output controllable rotation torque and rotation angle. The rotating gripper 24 can perform multiple operations: First, it grips the body of the solid fragrance storage bottle 32, completing the transfer and transportation of the storage bottle from the solid fragrance storage rack 31 to the storage bottle fixing plate 52; Second, it grips the knob 323 at the top of the solid fragrance storage bottle 32, outputting a set torque to rotate it, and through the knob 323, it links the stirring rod 324 to rotate, completing the stirring and dispensing of the powdered fragrance inside the bottle; Third, it grips the clamping module 51, and with the downward pressure of the Z-axis slide 21, it moves the clamping module 51 to the detection station of the detection unit, applying clamping force to the powder sample on the crystal surface, and after the detection is completed, it clamps the clamping module 51 and sends it back to its original position; Fourth, it grips the upper cylindrical end of the powder suction tube fixing seat 42, takes out the powder suction tube assembly from the powder suction tube placement rack 43 and moves it to the detection station, and after the suction operation is completed, it accurately puts the powder suction tube fixing seat 42 back into the powder suction tube placement rack 43 to complete the return.

[0033] This unit, through a set of three-axis motion modules and a single set of upper rotating grippers 24, can handle multiple operations such as sample transfer, screwing and unloading, tooling pick-and-place, and consumable handling. It eliminates the need to set up multiple independent clamping actuators for different work objects, greatly simplifying the overall mechanical structure of the machine and reducing the number of equipment parts and manufacturing costs. The three-axis slide table works together to ensure the positioning accuracy of the grippers and the repeatability of the positioning accuracy of each station, providing a reliable motion execution foundation for the fully automated operation of the entire device.

[0034] See Figure 6 The solid flavoring supply unit 3 is located in the working area of ​​the frame and is mainly used to store multiple sets of powdered tobacco flavoring samples to be tested, so as to realize the positioning and storage of sample bottles and controllable discharge. It includes a solid flavoring storage rack 31 and a solid flavoring storage bottle 32. The solid flavoring storage bottle 32 includes an upper cavity 321, a lower cavity 322, a knob 323, a stirring rod 324, a guide ring 325, and a plug 326.

[0035] The solid flavor storage rack 31 is a detachable bracket structure that can be completely removed from the machine frame. Multiple positioning and limiting holes are provided on the bracket plate surface, allowing for the simultaneous positioning and placement of multiple solid flavor storage bottles 32. Operators can remove the solid flavor storage rack 31 entirely from the machine frame to complete batch sample loading. After loading, the rack can be reinstalled, enabling centralized loading of multiple powder flavor samples and avoiding sample loading within the confined space of the equipment. Each solid flavor storage bottle 32 is independently positioned on the solid flavor storage rack 31, preventing tipping or displacement during equipment movement and facilitating individual gripping and transfer by the upper rotating jaws 24 of the lifting and rotating clamping unit 2.

[0036] The solid flavoring storage bottle 32 serves as a storage and dispensing carrier for powdered flavorings. The upper cavity 321 of the bottle is the main storage chamber for the powdered flavorings, used to hold the powdered tobacco flavorings to be tested. The lower cavity 322 has a downward-convex cone structure, facilitating the powder to converge towards the bottom outlet and reducing powder residue accumulation. The bottom of the lower cavity 322 is not sealed but is blocked in conjunction with the stirring rod 324. A knob 323 is mounted on the top of the upper cavity 321, and the knob 323 is linked to the internal stirring rod 324. A spring is installed between the knob 323 and the stirring rod 324, and a notch is provided at the bottom of the stirring rod 324.

[0037] Under normal conditions, the stirring rod 324 is pulled by the spring, and the bottom of the stirring rod 324 is sealed and blocked with the bottom of the lower cavity 322 of the storage bottle. When it is necessary to release the powder, the knob 323 is pressed by the upper rotating jaw 24. At this time, the stirring rod 324 is under pressure, and the bottom of the stirring rod 324 is separated from the bottom of the lower cavity 322 of the storage bottle. Then, when the upper rotating jaw 24 clamps the knob 323 and outputs the rotation torque, the knob 323 drives the stirring rod 324 to rotate and stir inside the cavity of the storage bottle, breaking up the bridging and clumping phenomenon that easily occurs in powdered fragrances. At the same time, due to the presence of the opening, the powder material flows smoothly downward.

[0038] A guide ring 325 is positioned at the outlet of the storage bottle, providing radial constraint on the lower end of the stirring rod 324. This restricts radial swaying of the stirring rod 324 during operation, preventing it from bumping or scraping against the inner wall of the storage bottle cavity and ensuring smooth rotation. A plug 326 is mounted on the side of the outlet of the lower cavity 322 of the storage bottle, allowing for on / off control of the outlet. During sample transfer and static storage, the plug 326 seals the outlet to prevent accidental spillage of the powdered flavoring. During dispensing, the rotation of the stirring rod 324, in conjunction with the opening of the plug 326, allows the powdered flavoring to be released downwards from the outlet. The plug 326 features a detachable assembly structure, facilitating the cleaning of residual powder inside the storage bottle and the replacement and maintenance of components.

[0039] This unit works in conjunction with the lifting and rotating clamping unit 2. First, the upper rotating gripper 24 grabs and removes the solid fragrance storage bottle 32 from the solid fragrance storage rack 31, and then transfers it to the storage bottle fixing plate 52 of the powder release and pressing unit 5 to complete the positioning. This provides material supply for the subsequent accurate release of powder to the detection station of the detection unit, realizing the automated feeding of powder fragrance samples without the need for manual intervention in the powder scooping and sample addition operations.

[0040] See Figure 8 The negative pressure waste suction and reset unit 4 is fixedly arranged in the working space of the frame. It is specifically used to remove the residual powder smoke fragrance on the surface of the test crystal after the test is completed, eliminate cross-contamination caused by sample residue, and realize the automatic pick-up and return of the powder suction tool. The unit includes a powder suction tube 41, a powder suction tube fixing seat 42, and a powder suction tube placement rack 43. The unit is connected to an external negative pressure material suction assembly as a suction power source.

[0041] The powder suction tube placement rack 43 is rigidly fixed to the side wall of the frame and serves as a standby storage base for the powder suction tube assembly. The rack is provided with a positioning groove to limit the placement of the powder suction tube fixing seat 42, ensuring that the powder suction tube 41 is stable in standby mode and will not shake or shift. At the same time, it provides a standard gripping position for the upper rotating jaw 24 of the lifting and rotating clamping unit 2.

[0042] The powder suction tube holder 42 serves as the support base for the powder suction tube 41. Its upper cylindrical end is positioned for gripping by the upper rotating jaws 24. This cylindrical end has a regular shape, facilitating jaw closure and tightening, ensuring reliable torque and displacement transmission. The powder suction tube 41 is securely mounted inside the powder suction tube holder 42, forming an integrated, transportable module. The rear end of the powder suction tube 41 is connected to an external negative pressure suction assembly, while the front end is a powder suction port. The entire module can be removed from the powder suction tube placement frame 43 by the upper rotating jaws 24 and then returned to its original position within the positioning groove of the powder suction tube placement frame 43 after operation.

[0043] When the equipment performs the residual powder cleaning process, the lifting and rotating clamping unit 2 moves horizontally in coordination with the X-axis slide 22 and Y-axis slide 23, and then moves vertically with the Z-axis slide 21 to drive the upper rotating gripper 24 to move above the powder suction tube placement frame 43. It then moves down to clamp the upper cylindrical end of the powder suction tube fixing seat 42, lifting and removing the powder suction tube 41 together with the powder suction tube fixing seat 42. Subsequently, the three-axis slides work together to move the front suction port of the powder suction tube 41 to the top of the detection crystal of the detection unit. The Z-axis slide 21 is finely adjusted to make the tube opening of the powder suction tube 41 close to the working surface of the crystal, maintaining a reasonable suction gap.

[0044] The external negative pressure suction assembly is activated, creating a negative pressure inside the pipeline. The powder fragrance remaining on the surface of the detection crystal is drawn away through the powder suction tube 41, completing the removal of residual powder from the crystal surface. This prevents powder residue from the previous sample from interfering with the spectral detection of the next set of samples, ensuring the repeatability of data from continuous testing. After the suction operation is completed, the external negative pressure suction assembly is deactivated, cutting off the negative pressure suction. The three-axis slide stage then re-energizes, moving the powder suction tube holder 42 back to the positioning groove of the powder suction tube placement frame 43. After the Z-axis slide stage 21 descends to its final position, the upper rotating jaw 24 releases its grip, completing the return of the powder suction tube assembly to its ready-to-go state.

[0045] This unit relies on the lifting and rotating clamping unit 2 to realize the automatic handling of tooling without the need for an additional independent drive mechanism, simplifying the overall structure; it uses negative pressure suction to clean powder residues without the need for cleaning fluid or wiping consumables, resulting in high cleaning efficiency and adaptability to the cleaning needs of continuous automated detection of multiple batches of powder fragrances.

[0046] See Figure 7 The powder release and compaction unit 5 is arranged in the working area of ​​the frame. It receives the solid fragrance storage bottle 32 transferred from the solid fragrance supply unit 3, completes the release of powder fragrance to the detection station, and compacts the powder sample that falls onto the detection crystal to ensure that the powder sample and the detection crystal are in full contact. The unit includes a compaction module 51, a storage bottle fixing plate 52, and a slide assembly 53.

[0047] The storage bottle fixing plate 52 serves as a temporary support station for the solid flavoring storage bottle 32. The plate has a positioning slot that matches the shape of the solid flavoring storage bottle 32. When the upper rotating jaw 24 of the lifting and rotating clamping unit 2 picks up the solid flavoring storage bottle 32 from the solid flavoring storage rack 31 and transfers it over, the solid flavoring storage bottle 32 is placed into the positioning slot of the storage bottle fixing plate 52 to achieve circumferential and radial positioning of the bottle, preventing the solid flavoring storage bottle 32 from shifting or tipping over during the subsequent twisting and unloading process, and ensuring that the bottle position remains stable.

[0048] The slide assembly 53 is a horizontal two-dimensional motion module, which is installed and fixed on the frame. The motion output end of the slide assembly 53 is rigidly connected to the storage bottle fixing plate 52, which can drive the storage bottle fixing plate 52 and the solid fragrance storage bottle 32 placed on it to move X in the horizontal plane. The slide assembly moves in the Y direction. After the upper rotating gripper 24 completes the unloading of the storage bottle, the slide assembly 53 receives a signal from the main control system to adjust its displacement, driving the outlet of the solid fragrance storage bottle 32 to move directly above the detection crystal of the detection unit. This ensures that the outlet is vertically aligned with the detection station, guaranteeing that the subsequently released powdered fragrance can accurately fall onto the effective working surface of the detection crystal, preventing powder from scattering on the outside of the crystal and causing material waste and contamination of the mechanism. After the powder is unloaded, the slide assembly 53 can also move the storage bottle fixing plate 52 away from the detection station, freeing up space for the insertion of the clamping module 51.

[0049] The clamping module 51 is an independent tooling component without self-powered operation. Its overall structural strength is high, and it can be stably held by the upper rotating gripper 24. After the powdered fragrance falls and spreads onto the surface of the detection crystal, the upper rotating gripper 24 of the lifting and rotating clamping unit 2 moves to the storage position of the clamping module 51 and clamps it. The X-axis slide 22 and Y-axis slide 23 work together to move the clamping module 51 above the detection station. Then, the Z-axis slide 21 feeds downwards, providing a controllable downward pressure load, pressing the clamping module 51 against the surface of the powdered fragrance, compacting the loose powder, promoting close contact between the powder sample and the detection crystal, reducing internal voids in the sample, improving the signal quality of infrared spectral acquisition, and reducing spectral noise. After all spectral acquisition is completed, the upper rotating gripper 24 clamps the clamping module 51 again, the Z-axis slide 21 rises, and in conjunction with the XY-axis slide translation, the clamping module 51 is returned to its original storage position, completing the clamping module reset.

[0050] This unit works in conjunction with the lifting and rotating clamping unit 2 and the solid flavor supply unit 3. It relies on the slide assembly 53 to achieve precise positioning of the storage bottle. The three-axis slide of the lifting and rotating clamping unit 2 is reused to provide the clamping driving force, eliminating the need for additional clamping drive cylinders or motors, thus simplifying the configuration of the entire machine. It not only achieves fixed-point feeding of powdered flavor but also completes the automated compaction of powdered samples, eliminating manual sample laying and pressing operations. This ensures that the process conditions for sample laying and pressing are consistent each time, improving the repeatability of test results for multiple sets of samples.

[0051] Example 2: This embodiment further describes the method of using the device of this application, based on Embodiment 1. See also... Figure 9 Its usage includes the following steps: S1. The upper rotating gripper 24 grabs the solid fragrance storage bottle 32 on the solid fragrance storage rack 31 and transfers it to the storage bottle fixing plate 52. S2, the slide assembly 53 drives the storage bottle fixing plate 52 to move, so that the mouth of the solid fragrance storage bottle is vertically aligned with the detection station; S3. The upper rotating jaw 24 holds the storage bottle and rotates the knob to release the powdered fragrance onto the surface of the detection crystal; S4. The upper rotating gripper 24 clamps and moves the pressing module 51 to the detection station to press the powdered fragrance. S5. The spectrometer collects the infrared spectral signal of the compressed powdered fragrance to complete the quality consistency test; S6. The upper rotating gripper 24 returns the clamping module 51 to its original position, and then clamps the powder suction tube 41 and moves it to the detection station. S7. Activate the external negative pressure suction assembly to remove residual powder from the surface of the detection crystal through the powder suction tube 41; S8, the powder suction tube 41 returns to its original position, and it is determined whether there is a next sample to be tested. If there is, it returns to S1; otherwise, the test ends.

[0052] The specific process of step S1 includes: After receiving the sample testing task instruction, all motion axes of the machine return to zero and reset, and the lifting and rotating clamping unit 2 enters the standby state. The X-axis slide 22 and Y-axis slide 23 receive the position instructions from the main control system, and the two work together to perform horizontal interpolation motion, driving the Z-axis slide 21 and the upper rotating gripper 24 to move horizontally as a whole, so that the upper rotating gripper 24 accurately moves to the position directly above the target solid fragrance storage bottle 32 to be tested in the solid fragrance storage rack 31 in the solid fragrance supply unit 3, completing the horizontal alignment.

[0053] After horizontal positioning is completed, the Z-axis slide 21 drives the upper rotating jaw 24 to feed vertically downwards, and adjusts the downward depth so that the clamping mouth of the upper rotating jaw 24 is aligned with the clamping part of the solid fragrance storage bottle 32. Then the clamping mechanism of the upper rotating jaw 24 closes and holds the bottle body of the solid fragrance storage bottle 32 with a preset clamping force, completing the stable clamping of the bottle body and ensuring that the bottle body will not slip or shake during the transfer process.

[0054] After confirming that the clamping is correct, the Z-axis slide 21 drives the upper rotating gripper 24 to lift vertically upward, lifting the solid fragrance storage bottle 32 from its positioning position in the solid fragrance storage rack 31, so that the storage bottle is completely freed from the rack's limit. Then, the X-axis slide 22 and Y-axis slide 23 move together again, moving the clamped solid fragrance storage bottle 32 horizontally and transferring it to directly above the storage bottle fixing plate 52 of the powder release and clamping unit 5.

[0055] The three-axis slide table is finely adjusted to align the outer contour of the solid fragrance storage bottle 32 vertically with the positioning slot on the storage bottle fixing plate 52. Then, the Z-axis slide table 21 drives the upper rotating gripper 24 vertically downwards, smoothly placing the solid fragrance storage bottle 32 into the positioning slot of the storage bottle fixing plate 52, using the slot to achieve radial and circumferential positioning of the bottle. After the bottle is reliably positioned, the upper rotating gripper 24 opens its gripping opening to release the bottle. Finally, the Z-axis slide table 21 drives the upper rotating gripper 24 to slightly lift it upwards, away from the bottle area, avoiding subsequent mechanism movements. This completes the entire process of gripping, transferring, and placing the solid fragrance storage bottle, proceeding to step S2.

[0056] The specific process of step S2 includes: After step S1 completes the placement and locking of the solid fragrance storage bottle 32 onto the storage bottle fixing plate 52, and the upper rotating gripper 24 is raised to avoid the working area, the entire machine enters the powder feeding and alignment process. The main control system sends a motion command to the slide assembly 53 of the powder release and clamping unit 5. The slide assembly 53 starts, moving the storage bottle fixing plate 52 and the solid fragrance storage bottle 32, which has been limited and fixed, together in the X... It performs precise translational motion within the Y-plane.

[0057] During the movement, the system reads the position feedback signal of the slide assembly 53 in real time, continuously corrects the displacement, and drives the outlet of the solid fragrance storage bottle 32 to move above the detection station of the detection unit, so that the bottom outlet of the lower cavity 322 of the storage bottle is vertically aligned with the center detection station of the detection crystal, ensuring that the powder fragrance released later can fall directly into the effective working surface of the detection crystal, avoiding powder from falling to the outside of the crystal, causing material waste and powder contamination inside the mechanism.

[0058] Upon reaching the target alignment position, the slide assembly 53 stops moving and locks in position, eliminating residual vibrations and maintaining a stable relative position between the outlet of the solid fragrance storage bottle 32 and the inspection station, preventing positional deviation during the unloading process. At this time, the X-axis slide 22 and Y-axis slide 23 of the lifting and rotating clamping unit 2 work together to drive the upper rotating gripper 24 to move directly above the knob 323 at the top of the solid fragrance storage bottle 32, completing the pre-alignment and preparing the position for the subsequent step S3 of clamping the knob to perform the rotating unloading action. This completes the entire operation process of step S2, and the process proceeds to step S3.

[0059] The specific process of step S3 includes: After step S2 completes the vertical alignment and locking of the solid flavor storage bottle 32 outlet with the detection station, and after the upper rotating gripper 24 has moved to the predetermined position above the knob 323, the equipment performs the automatic powder flavor dispensing and release process.

[0060] The Z-axis slide 21 receives the main control command and drives the upper rotating jaw 24 to feed vertically downward. The downward stroke is adjusted so that the gripping jaw of the upper rotating jaw 24 accurately fits the knob 323 at the top of the solid fragrance storage bottle 32. Then the upper rotating jaw 24 clamping mechanism closes to clamp the knob 323 with the set torque, ensuring reliable clamping and avoiding slippage and free rotation during the rotation process.

[0061] After clamping and locking, the rotation drive mechanism inside the upper rotating jaw 24 is activated, outputting a preset number of rotations and rotation torque, driving the knob 323 to rotate synchronously. The knob 323, in conjunction with the stirring rod 324 inside the bottle, rotates together. The stirring rod 324 continuously stirs the powdered fragrance inside the upper cavity 321 and lower cavity 322 of the storage bottle, breaking up the bridging and clumping phenomena that easily occur in the powdered fragrance and eliminating the risk of powder blockage. During the rotation of the stirring rod 324, it is radially constrained by the guide ring 325, preventing it from swaying and hitting the inner wall of the bottle. As the knob 323 rotates, the plug 326 at the outlet of the lower cavity 322 of the storage bottle opens, and the powdered fragrance inside the bottle falls continuously downward from the outlet under the action of gravity, falling vertically onto the surface of the detection station of the detection crystal below, forming a loosely spread powder sample layer on the crystal.

[0062] Once the system count reaches the preset number of rotations and the quantitative powder release is completed, the rotation drive mechanism of the upper rotating gripper 24 stops working, ending the feeding action. Subsequently, the Z-axis slide 21 drives the upper rotating gripper 24 to lift slightly upwards, releasing its grip on the knob 323, allowing the gripper jaws to completely disengage from the knob 323 and avoid the top of the storage bottle. At this time, the solid fragrance storage bottle 32 is still limited and fixed by the slot of the storage bottle fixing plate 52, maintaining its position and preventing the bottle from shifting as the gripper lifts.

[0063] The slide assembly 53 receives the instruction and moves the storage bottle fixing plate 52 and the solid fragrance storage bottle 32 horizontally away from the detection station, making room for the working space above the detection crystal and avoiding the storage bottle from blocking and interfering with the subsequent pressing operation. This completes all the processes in step S3 and proceeds to step S4.

[0064] The specific process of step S4 includes: Step S3 completes the process of the powdered fragrance falling and being placed on the surface of the detection crystal, and the slide assembly 53 has moved the solid fragrance storage bottle 32 away from the detection station. After the working space above the detection station is completely cleared, the equipment enters the powder compaction process.

[0065] The lifting and rotating clamping unit 2 receives the action command from the main control system. The X-axis slide 22 and the Y-axis slide 23 work together to perform horizontal interpolation motion, which drives the Z-axis slide 21 and the upper rotating gripper 24 to move horizontally as a whole, so that the upper rotating gripper 24 is accurately positioned directly above the storage position of the clamping module 51 of the powder release and clamping unit 5, and the horizontal pre-alignment is completed.

[0066] After horizontal positioning is completed, the Z-axis slide 21 drives the upper rotating jaw 24 to feed vertically downward, so that the jaw jaws are aligned with the clamping part of the clamping module 51; the clamping mechanism of the upper rotating jaw 24 closes, and the clamping force is set to hold the clamping module 51 tightly, ensuring that the clamping is firm and that there will be no loosening or displacement during the clamping operation.

[0067] After clamping, the Z-axis slide 21 rises upward, lifting the clamping module 51 from its original storage position. Subsequently, the X-axis slide 22 and Y-axis slide 23 move in tandem, transferring the clamping module 51 directly above the detection station of the crystal in the detection unit. The three-axis slides complete position calibration, ensuring that the pressing end face of the clamping module 51 is vertically aligned with the loosely spread powdered fragrance on the crystal surface.

[0068] The Z-axis slide 21 performs a controllable downward feed motion, outputting a set downward pressing stroke. Relying on the axial pressure of the Z-axis slide 21, the pressing end face of the clamping module 51 presses against the surface of the powdered fragrance, compacting the loose powdered fragrance and compressing the gaps between powder particles. This ensures that the powder sample and the working surface of the detection crystal are fully and tightly adhered, reducing interference from air gaps on the infrared spectral signal. After compaction, a short holding time is maintained to ensure the compaction effect.

[0069] After the pressure holding process is completed, the Z-axis slide 21 drives the upper rotating gripper 24 to lift vertically upward, causing the clamping module 51 to leave the surface of the powder fragrance sample, thus completing the clamping operation. At this time, the clamping module 51 is still held by the upper rotating gripper 24 and is not directly returned to its original position, in preparation for the subsequent return action in S6. The compacted powder fragrance at the detection station is completely retained on the surface of the detection crystal, thus completing the entire process of step S4 and proceeding to step S5, the spectral acquisition process.

[0070] The specific process of step S5 includes: Step S4 completes the compaction of the powdered fragrance. The Z-axis slide 21 drives the clamping module 51 to lift away from the sample surface. The compacted powdered fragrance is completely retained on the detection station of the detection crystal. All moving mechanisms of the whole machine stop moving to avoid interference from the vibration of the mechanism to the spectral acquisition. The equipment enters the spectral signal acquisition and quality consistency detection process.

[0071] The main control system sends acquisition commands to the spectrometer in the detection unit, and the spectrometer starts working based on ATR. The FTIR principle is used to collect infrared spectra of compressed powdered tobacco flavoring samples. Infrared light is incident on the detection crystal, and the fundamental frequency vibration characteristic spectrum information of the powdered flavoring molecules is collected by utilizing the attenuation total reflection effect on the crystal surface, thus obtaining complete infrared spectrum data of the sample under test.

[0072] During the data acquisition process, all motion axes of the equipment are kept locked and stationary to eliminate mechanical vibrations caused by the movement of the slide table, avoid introducing spectral noise through vibration, and ensure the signal-to-noise ratio of the acquired spectra. The spectrometer transmits the acquired raw spectral data to the main control system of the entire machine. The system retrieves the pre-stored standard fragrance reference spectrum, compares the spectrum of the sample to be tested with the standard reference spectrum, performs sample similarity calculation, realizes the quality consistency judgment of powdered tobacco fragrance, and outputs the test results of this sample.

[0073] After the entire spectral acquisition and comparison process is completed, the spectrometer ends its acquisition work and enters standby mode. At this time, the surface of the crystal still retains the compacted powder fragrance sample, waiting for the subsequent residual powder cleaning process; the upper rotating gripper 24 remains in the clamping state of the clamping module 51, does not perform the return action, and directly proceeds to step S6 to carry out the return of the clamping module and the powder suction tube to pick up the material.

[0074] The specific process of step S6 includes: Step S5 completes the infrared spectrum acquisition of powdered fragrance and quality consistency judgment. The upper rotating gripper 24 still holds the clamping module 51 in the state. After the whole machine is started, the cleaning preparation process is carried out.

[0075] The X-axis slide 22 and Y-axis slide 23 of the lifting and rotating clamping unit 2 move horizontally in coordination, driving the Z-axis slide 21 and the clamped clamping module 51 to move horizontally together, displacing the clamping module 51 to its original storage position. When the clamping module 51 moves directly above the storage position, the X-axis slide 22 and Y-axis slide 23 stop moving, completing the horizontal positioning. Then, the Z-axis slide 21 drives the upper rotating jaw 24 to feed vertically downward, smoothly placing the clamping module 51 onto the preset storage base; after reaching the position, the jaws of the upper rotating jaw 24 open, releasing the clamping module 51 and completing the release and return of the clamping module to its original position.

[0076] After the clamping module returns to its original position, the Z-axis slide 21 is slightly raised, causing the upper rotating gripper 24 to leave the clamping module area. The X-axis slide 22 and Y-axis slide 23 then work together again to drive the upper rotating gripper 24 to move horizontally to above the powder suction tube placement frame 43 of the negative pressure waste suction and reset unit 4, and to complete the horizontal pre-alignment by aligning it with the upper cylindrical end of the powder suction tube fixing seat 42.

[0077] The Z-axis slide 21 feeds downwards again, driving the upper rotating gripper 24 to descend. The gripper precisely covers the upper cylindrical end of the powder suction tube fixing seat 42, and closes to apply a preset clamping force to hold the cylindrical end firmly, ensuring a secure clamping and preventing the powder suction tube assembly from loosening during transport. After the clamping is confirmed, the Z-axis slide 21 is raised upwards, lifting the powder suction tube 41 and the powder suction tube fixing seat 42 together from the positioning groove of the powder suction tube placement frame 43.

[0078] The X-axis slide 22 and Y-axis slide 23 move together to move the suction front end of the powder suction tube 41 to the detection station of the detection crystal in the detection unit. The Z-axis slide 21 is finely adjusted to control the tube opening of the powder suction tube 41 to maintain a suitable suction working gap with the surface of the detection crystal, in preparation for the next step of negative pressure suction to remove residual powder. This completes all the work in step S6 and proceeds to step S7.

[0079] The specific process of step S7 includes: Step S6 completes the gripping and transfer of the powder suction tube 41. The suction port of the powder suction tube 41 has been adjusted to the working position at the preset suction gap distance from the surface of the detection crystal, and the whole machine enters the residual powder negative pressure removal process.

[0080] The main control system issues a command to activate the external negative pressure suction assembly connected to the negative pressure waste suction and reset unit 4. A negative pressure is quickly established inside the pipeline, and the suction force is transmitted to the front end of the powder suction pipe 41. Relying on the airflow generated by the negative pressure, the powder and fragrance residue remaining on the surface of the detection crystal after detection are absorbed and collected. The loose powder residue is carried by the airflow and transported through the powder suction pipe 41 to the powder collection container of the external negative pressure suction assembly, thus achieving separation of the residual powder from the detection crystal.

[0081] During the suction operation, the lifting and rotating clamping unit 2 can make small adjustments to the vertical height of the powder suction tube 41 through the Z-axis slide 21, and work with the X-axis slide 22 and Y-axis slide 23 to perform small-range point reciprocating sweeping, so that the nozzle of the powder suction tube 41 traverses the entire detection working surface of the detection crystal, and comprehensively removes the residual powder particles in each area of ​​the crystal, avoiding local powder residue and eliminating the risk of cross-contamination caused by residual powder to the next set of samples.

[0082] The system maintains negative pressure for the preset suction duration to ensure thorough removal of residual powder from the crystal surface. When the suction timer ends, the main control system stops the external negative pressure suction assembly, cuts off the negative pressure air source, and gradually releases the negative pressure in the pipeline, terminating the powder suction action. At this time, the powder suction tube 41 is still held by the upper rotating jaw 24, maintaining its current posture and not being released directly, preparing for the tooling return action in S8. This completes the entire operation process of step S7 and proceeds to step S8.

[0083] The specific process of step S8 includes: Step S7 completes the residual powder suction operation on the surface of the crystal. The external negative pressure suction component has stopped working, and the powder suction tube 41 is still held by the upper rotating jaw 24. The equipment performs the powder suction tube component return and sample circulation judgment process.

[0084] The X-axis slide 22 and Y-axis slide 23 of the lifting and rotating clamping unit 2 work together to perform horizontal interpolation motion, driving the Z-axis slide 21, the upper rotating gripper 24 and the powder suction tube assembly to move horizontally as a whole, and moving the powder suction tube fixing seat 42 to the positioning groove directly above the powder suction tube placement rack 43 of the negative pressure waste suction and reset unit 4, thus completing the horizontal alignment.

[0085] After horizontal positioning is completed, the Z-axis slide 21 drives the upper rotating gripper 24 to feed vertically downwards, smoothly placing the powder suction tube fixing seat 42 into the positioning groove of the powder suction tube placement frame 43. The groove provides circumferential and radial limiting for the powder suction tube fixing seat 42, ensuring that the placement posture meets the standby requirements. After placement, the clamping mechanism of the upper rotating gripper 24 opens, releasing the grip on the cylindrical end of the powder suction tube fixing seat 42; then, the Z-axis slide 21 drives the upper rotating gripper 24 to lift upwards, completely disengaging the gripper from the powder suction tube fixing seat 42, completing the complete return of the powder suction tube assembly.

[0086] After the powder suction tube returns to its original position, the entire machine's motion mechanism performs a preliminary reset, and the upper rotating gripper 24 returns to the waiting position. The main control system reads the task list to determine if there are any untested powder fragrance samples. If it determines that there is another sample to be tested, the program jumps back to step S1 and repeats the entire testing process of bottle grabbing, transfer, feeding, compaction, spectral acquisition, and residual powder cleaning, achieving uninterrupted continuous sample testing. If it determines that all samples have been tested and there are no remaining samples, each slide performs a zero-point return action, all moving parts return to their initial standby position, and the spectrometer and external negative pressure suction assembly sequentially switch to standby mode, ending the entire testing task. This completes one complete equipment testing cycle.

[0087] In summary, the present invention has the following advantages: This invention is based on ATR FTIR technology enables fully automated detection of the consistency of powdered tobacco flavorings. The device utilizes five functional units to collaboratively construct an automated operation chain, eliminating the need for complex organic solvent pretreatment and requiring only a small amount of powder sample for spectral acquisition, effectively meeting the rapid screening needs of industrial sites. This invention leverages a lifting and rotating clamping unit to reuse a single set of upper rotating grippers to complete various operations such as sample transfer, knob-operated feeding, and tooling placement, simplifying the overall hardware configuration and reducing equipment costs. A dedicated solid flavoring storage bottle uses a stirring rod to agitate the material, improving powder bridging and ensuring uniform and stable powder feeding. After detection, a negative pressure suction method is used to remove residual powder from the ATR detection crystal, eliminating the need for wiping consumables and efficiently eliminating sample cross-contamination, ensuring consistent continuous detection conditions. The three-axis slide stage enables high-precision positioning at each station, and the powder is automatically compressed and fully adhered to the crystal, improving the signal-to-noise ratio of the infrared spectrum and the reproducibility of the detection results. The equipment supports the overall disassembly and loading of sample trays, making operation and maintenance convenient. It can achieve continuous high-throughput detection of multiple powder flavorings, effectively improving the automation level of tobacco flavoring quality evaluation.
