Description

Technical Field

[0001] This disclosure relates to the field of beef and mutton testing technology, and in particular to a non-destructive testing device and method for beef and mutton quality. Background Technology

[0002] Meat is considered a high-protein, nutritious, and delicious food. Beef and mutton are important components of meat products. Therefore, it is crucial to ensure the safety and quality of beef and mutton to safeguard the food safety of residents. Freshness is a comprehensive indicator used to evaluate the safety and quality of meat products. People usually judge the freshness of meat products based on appearance, smell, texture, and shelf life. Although these methods can accurately detect freshness indicators, they are limited to a single indicator, and the latter two are destructive and time-consuming, which is not conducive to the real-time on-site detection of beef and mutton freshness in cold chain logistics.

[0003] According to patent document CN118190911U, a novel rapid and non-destructive testing device for the freshness of beef and mutton is disclosed. The device includes a base with a strip-shaped groove at its top. A tray is placed inside the groove. A mounting frame is mounted on the top of the groove, and a Raman spectrometer and a first PLC controller are mounted on the mounting frame. The Raman spectrometer and the first PLC controller are connected to a host computer. Several connecting posts are rotatably connected to the bottom of the groove. The lower ends of the connecting posts extend into the inner cavity of the base and are connected to driven gears. The driven gears mesh with a first rack, which has teeth on its front side. A first motor is located inside the base cavity. The output shaft of the first motor... The device has an active wheel at one end, which meshes with a first rack. In use, this technology measures the spectral data of the meat sample on the tray using a Raman spectrometer. The host computer identifies the meat and then inputs the corresponding beef and mutton freshness discrimination models to obtain the freshness discrimination results. This achieves rapid and non-destructive detection of beef and mutton freshness. Identifying the meat first and then using the corresponding discrimination model also improves detection accuracy. However, while this solution achieves freshness detection, it cannot simultaneously adjust the height of the meat while adjusting the tension of the conveyor, nor can it adjust the distance between the detection mechanism and the meat, resulting in inconvenience during use.

[0015] A non-destructive testing method for beef and mutton quality, the testing method comprising the following steps: Step 1: Preliminary preparation. Place the beef or mutton to be tested in a room temperature environment to allow it to warm up. Remove the packaging, blood, tendons, and impurities from the surface of the meat to ensure that the testing surface is flat and unobstructed. If it is a whole piece of meat or a piece of meat, the testing surface needs to be trimmed into a flat cut surface. Step 2: Sample positioning. Determine the testing points according to the testing requirements. For whole meat or meat pieces, select representative areas. Select multiple testing points for each piece of meat, and directly use the effective edible area of ​​the meat as the testing surface. Step 3: Implementation of the test. Start the equipment's test program and scan, collect, and detect each test point on the meat according to the preset parameters. Repeat the test 2-3 times for each test point to avoid random errors in a single test. During the test, near-infrared spectroscopy is used. The spectral probe is aligned with the test point, and diffuse reflection or transmission scanning is activated. The scanning range covers the target wavelength, and the spectral curve is recorded. Then, AI vision inspection is performed using a camera. An industrial camera collects images of the meat test surface. At the same time, color sensors and texture sensors are used to record visual features such as the color, texture, and intramuscular fat distribution of the meat. Step 4: Data Acquisition. The equipment automatically collects the raw data from each detection point, automatically transmits the data to the equipment's terminal or computer, saves it in a standardized data format, and preprocesses the data to remove abnormal data. Step 5: Result determination. Based on national or industry beef and mutton quality standards and testing requirements, the analyzed data are comprehensively determined, and the meat products are classified into four grades: superior, first-class, qualified, and unqualified.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: In this invention, a threaded rod pushes a threaded sleeve to move, and the displacement of the threaded sleeve is lifted to the drive seat by a connecting rod. The drive seat pushes the active roller to move up and down. When the active roller moves upward, it pushes the conveyor belt to bulge upward. After the conveyor belt bulges, it carries the meat out and moves it upward to adjust the distance between it and the detection mechanism. In addition, the downward movement of the active roller later pushes the conveyor belt to form a concave distribution. The bottom of the conveyor belt contacts the sponge cylinder. Under the push of the conveyor belt, the sponge cylinder contacts the cleaning liquid or disinfectant inside the water tank. The conveyor belt drives the sponge cylinder to rotate, extracting the liquid and moving it to the surface of the conveyor belt. In addition, the invention can also move the movable seat upward while the active roller is driven upward by the drive seat. The movable seat and the fixed seat are distributed with a high degree of offset on one side, so that one side of the meat can be moved with the movable seat as the fulcrum, and the meat can be moved towards the movable seat for positioning and placement. This makes it easy to move the meat in a straight line from the detection mechanism for detection. When the conveyor belt drives the sponge cylinder downward again later, the liquid inside the water tank is discharged. The sponge cylinder rotates on the conical seat, which makes it easy to scrape off the excess liquid from the sponge cylinder. In this invention, the detection mechanism is installed inside the slot by a limiting rod and a mounting rod. The fixing bolt controls the tightness between the fixing plate and the adjusting plate. The detection mechanism slides the detection point inside the slot. In addition, the supplementary light at the bottom of the ring seat improves the optical detection of the detection mechanism with appropriate brightness, so as to achieve accurate detection of meat.

Detailed Implementation

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 9As shown, a non-destructive testing device for beef and mutton quality includes: a base 1, on which a support seat 2 and a fixed seat 5 are fixedly mounted; a slot 3 is formed on the support seat 2, and a testing component 4 is movably installed inside the slot 3; a driven roller 18 is movably mounted between the fixed seats 5, and a conveyor belt 6 is movably mounted on the driven roller 18; a testing component 4, including an adjusting plate 38 and a fixed plate 41; a limit rod 39 is welded to the inner wall of the adjusting plate 38, and an installation rod 40 is movably mounted inside the limit rod 39; the installation rod 40 is welded to the fixed plate 41, and a fixing bolt is rotatably mounted between the limit rod 39 and the installation rod 40; and a drive component 8, including a mounting seat 7, on which a motor seat 24 is welded, and a drive motor 23 is fixedly mounted on the motor seat 24. A threaded column 22 is fixed on the drive motor 23, and a threaded sleeve 25 is rotatably mounted on the threaded column 22. A drive seat 29 is movably mounted on the mounting base 7. Non-destructive testing of beef and mutton quality is a core quality inspection equipment for meat. Relying on mainstream non-destructive testing technologies such as near-infrared spectroscopy, Raman spectroscopy, and machine vision, it can achieve non-invasive and accurate detection of key indicators such as moisture, protein, fat, tenderness, veterinary drug residues, and microbial contamination in beef and mutton. The improvement of its detection accuracy, stability, and compliance is inseparable from the comprehensive support and deep integration of new material testing, metrology, related standardization, and certification and accreditation services. Later, the drive motor 23 drives the threaded column 22 to rotate. As the threaded column 22 rotates, the threaded sleeve 25 moves horizontally. The threaded sleeve 25 is provided with limit support for its horizontal movement by the positioning plate 21, thereby avoiding misalignment and shaking when the threaded sleeve 25 moves.

[0022] In this embodiment, a DC motor is fixedly mounted on the drive seat 29, and an active roller 11 is mounted on the DC motor. The active roller 11 is movably mounted between the conveyor belts 6. A protrusion 50 is welded onto the active roller 11. A groove 12 is formed on the inner wall of the conveyor belt 6, and the protrusion 50 is movably mounted inside the groove 12. A positioning plate 21 is welded to the bottom of the threaded sleeve 25. A positioning groove 20 is formed on the side of the mounting seat 7. The positioning plate 21 is movably mounted inside the positioning groove 20 through a positioning block. A fixing lug 26 is welded to the top of the threaded sleeve 25. A connecting rod 27 is movably mounted on one end of the fixing lug 26. A fixing shaft 28 is mounted on one end of the connecting rod 27. One end of the fixing shaft 28 is fixed to the drive seat 29. A tension mechanism 30 is fixed to the bottom of the drive seat 29. A movable plate 31 is welded to the side of the drive seat 29. A movable seat 17 is movably installed on the fixed seat 5. A sliding groove 15 is opened on the side of the fixed seat 5. A slider 16 is movably installed inside the sliding groove 15. One end of the slider 16 is welded to the mounting seat 7. After the DC motor is started, its output end drives the active roller 11 to rotate synchronously. The active roller 11 is movably mounted between the conveyor belts 6, and the protrusions 50 welded on the roller are adapted to and movably engaged with the grooves 12 opened on the inner wall of the conveyor belt 6. This meshing engagement of the protrusions 50 and the grooves 12 effectively avoids relative sliding between the active roller 11 and the conveyor belt 6, ensuring that power can be efficiently and losslessly transmitted to the conveyor belt 6, driving the conveyor belt 6 to run smoothly and realize continuous material conveying. At the same time, the engagement of the protrusions 50 and the grooves 12 also plays a certain guiding role in the running trajectory of the conveyor belt 6, preventing the conveyor belt 6 from deviating or running off course during movement. The tension mechanism 30 fixed at the bottom of the drive seat 29 provides continuous tension and reset force for the drive seat 29, ensuring that the drive seat 29 always maintains a stable initial position. At the same time, it can buffer the vibration generated during the rotation of the active roller 11 and the operation of the conveyor belt 6, reducing the impact of vibration on the overall structural stability. The movable plate 31 welded to the side of the drive seat 29 improves the stability of the drive seat 29 during installation and operation.

[0023] In this embodiment, a positioning post 46 is welded to the bottom of the movable seat 17, and a reset mechanism 47 is fixed to one end of the positioning post 46. The positioning post 46 is movably installed inside the fixed seat 5 through the reset mechanism 47. A fixing block 9 is welded to the side of the mounting seat 7. A water tank 13 is fixedly installed inside the fixed seat 5. A cleaning component 14 is rotatably installed inside the water tank 13. The cleaning component 14 includes a limiting groove 35. A limiting block 36 is movably installed inside the limiting groove 35. The limiting block 36 is installed inside the limiting groove 35 through a support mechanism 37. A roller 32 is rotatably mounted between the limiting blocks 36. A sponge tube 33 is fixedly mounted on the surface of the roller 32. A conical seat 34 is fixedly mounted inside the water tank 13. The conical seat 34 cooperates with the sponge tube 33. A drain pipe 19 is fixedly mounted between the water tank 13 and the fixed seat 5. The movable seat 17 serves as an auxiliary positioning component. It can drive the positioning column 46 to reset through the elastic action of the reset mechanism 47, thereby restoring the movable seat 17 to its initial positioning position and preventing the movable seat 17 from shifting and affecting the overall structural stability. The cleaning component 14 is used to clean the surface of the conveyor belt 6. The limiting groove 35 is a limiting block 36. A sliding guide is provided, and the limiting block 36 is movably installed in the limiting groove 35 through the support mechanism 37. The support mechanism 37 can flexibly adjust the height position of the limiting block 36, thereby driving the roller 32 and the sponge tube 33 to move up and down. The roller 32 is rotatably installed between the two sets of limiting blocks 36, and the sponge tube 33 fixed on its surface can fully absorb the cleaning liquid in the water tank 13. When the conveyor belt 6 is running, the sponge tube 33 contacts the surface of the conveyor belt 6, and the roller 32 rotates synchronously with the movement of the conveyor belt 6. The sponge tube 33 wipes and cleans the dust and impurities on the surface of the conveyor belt 6. The conical seat 34 fixed inside the water tank 13 is precisely matched with the sponge tube 33.

[0024] In this embodiment, a reinforcing plate 43 and a reinforcing rod are welded onto the fixed plate 41. A detection mechanism 42 is fixed to one end of the reinforcing rod. The detection mechanism 42 includes a spectrometer and an optical camera. A ring seat 44 is fixed to one end of the reinforcing plate 43, and a supplementary light 45 is fixedly installed inside the ring seat 44. A connecting groove 48 is opened on the side of the movable seat 17, and a connecting block 49 is movably installed inside the connecting groove 48. One end of the connecting block 49 is welded to the fixed seat 5. An opening 10 is opened between the fixed seats 5. The detection mechanism 42 consists of a spectrometer and an optical camera, and its installation position corresponds to the conveyor belt 6. The optical camera can capture image information on the surface of the conveyor belt 6. The ring seat 44 fixed to one end of the reinforcing plate 43, with the supplementary light 45 fixedly installed inside, can provide sufficient illumination in low-light conditions to compensate for the light affecting the detection mechanism 42. To ensure clear images captured by the optical camera and accurate data from the spectrometer, and to guarantee the stable operation of the testing work, the connecting groove 48 on the side of the movable seat 17 has a connecting block 49 installed inside, one end of which is welded to the fixed seat 5, forming an auxiliary guide structure for the movable seat 17. It works in conjunction with the original positioning column 46 and the reset mechanism 47. At the same time, the movable cooperation between the connecting block 49 and the connecting groove 48 can help the positioning column 46 to distribute the force on the movable seat 17, reduce the load on the reset mechanism 47, and extend the service life of the reset mechanism 47.

[0025] A non-destructive testing method for beef and mutton quality, the testing method comprising the following steps: Step 1: Preliminary preparation. Place the beef or mutton to be tested in a room temperature environment to allow it to warm up. Remove the packaging, blood, tendons, and impurities from the surface of the meat to ensure that the testing surface is flat and unobstructed. If it is a whole piece of meat or a piece of meat, the testing surface needs to be trimmed into a flat cut surface. Step 2: Sample positioning. Determine the testing points according to the testing requirements. For whole meat or meat pieces, select representative areas. Select multiple testing points for each piece of meat, and directly use the effective edible area of ​​the meat as the testing surface. Step 3: Implementation of the test. Start the equipment's test program and scan, collect, and detect each test point on the meat according to the preset parameters. Repeat the test 2-3 times for each test point to avoid random errors in a single test. During the test, near-infrared spectroscopy is used. The spectral probe is aligned with the test point, and diffuse reflection or transmission scanning is activated. The scanning range covers the target wavelength, and the spectral curve is recorded. Then, AI vision inspection is performed using a camera. An industrial camera collects images of the meat test surface. At the same time, color sensors and texture sensors are used to record visual features such as the color, texture, and intramuscular fat distribution of the meat. Step 4: Data Acquisition. The equipment automatically collects the raw data from each detection point, automatically transmits the data to the equipment's terminal or computer, saves it in a standardized data format, and preprocesses the data to remove abnormal data. Step 5: Result determination. Based on national or industry beef and mutton quality standards and testing requirements, the analyzed data are comprehensively determined, and the meat products are classified into four grades: superior, first-class, qualified, and unqualified.

[0026] Working principle: During use, the drive motor 23 is started to drive the threaded column 22 to rotate. When the threaded column 22 rotates, it pushes the threaded sleeve 25 to move. The threaded sleeve 25 moves horizontally under the limit of the positioning plate 21. When the threaded sleeve 25 moves, the fixed hanging ear 26 rotates at one end of the connecting rod 27. When rotating, it pushes the connecting rod 27 to rotate and tilt. When the connecting rod 27 is tilted, it pushes the drive seat 29 to move on the mounting seat 7. When the mounting seat 7 moves, the movable plate 31 moves at the same time. The slider 16 on the inner wall of the movable plate 31 pushes the movable seat 17 to move upward. After the movable seat 17 moves upward, it is distributed with a height misalignment with the fixed seat 5. The meat is placed on the conveyor belt 6. One side of the meat moves with the movable seat 17 as the support point to position the meat on the conveyor belt 6. After the meat is placed, when it is necessary to adjust the distance between the meat and the detection mechanism 42, the drive seat 29 remains stationary, and the active roller 11 pushes the top conveyor belt 6 to bulge upward. The DC motor is started to drive the active roller 11 to rotate. The protrusion 50 and the groove 12 cooperate to drive the conveyor belt 6 to move. When the protrusion 50 on the active roller 11 moves without contacting the groove 12, the conveyor belt 6 moves due to the friction of the active roller 11. After the conveyor belt 6 moves, the groove 12 adjusts its contact position with the protrusion 50 to achieve adaptive adjustment. After the meat moves to the protruding position of the conveyor belt 6, it moves close to the bottom of the detection mechanism 42 for detection. When the meat needs to be detected in a planar manner, the active roller 11 is moved downward. The active roller 11 pushes the lower conveyor belt 6 downward to squeeze it. After the conveyor belt 6 is squeezed downward, it does not contact the sponge cylinder 33. After the active roller 11 moves downward, the top conveyor belt 6 moves in a planar manner. When the conveyor belt 6 needs to be cleaned and disinfected later, the active roller 11 is lowered again. The active roller 11 pushes the bottom of the conveyor belt 6 to contact the sponge cylinder 33. With the squeezing force of the conveyor belt 6, the sponge cylinder 33 and the roller 32 move downward. The limiting block 36 squeezes the support mechanism 37 on the inner wall of the limiting groove 35. Among them, the support mechanism 37, the tension mechanism 30, and the reset mechanism 47 are all springs. After the sponge cylinder 33 descends, it comes into contact with the liquid surface inside the water tank 13 and adsorbs the liquid. After adsorbing the liquid, the sponge cylinder 33 rotates as the conveyor belt 6 moves. The rotation of the sponge cylinder 33 cleans or disinfects the surface of the conveyor belt 6. When it is necessary to clean the sponge cylinder 33 later, the liquid inside the water tank 13 is discharged outward, the bottom of the conveyor belt 6 descends again, and the sponge cylinder 33 contacts the top of the conical seat 34 under compression. While being compressed, the sponge cylinder 33 rotates. The conical seat 34 facilitates the scraping outward of the liquid remaining inside the sponge cylinder 33. The scraped liquid falls into the water tank 13 for later cleaning.

10. A non-destructive testing method for beef and mutton quality implemented by the device according to claim 1, characterized in that, The detection method includes the following steps: Step 1: Preliminary preparation. Place the beef or mutton to be tested in a room temperature environment to allow it to warm up. Remove the packaging, blood, tendons, and impurities from the surface of the meat to ensure that the testing surface is flat and unobstructed. If it is a whole piece of meat or a piece of meat, the testing surface needs to be trimmed into a flat cut surface. Step 2: Sample positioning. Determine the testing points according to the testing requirements. For whole meat or meat pieces, select representative areas. Select multiple testing points for each piece of meat, and directly use the effective edible area of ​​the meat as the testing surface. Step 3: Implementation of the test. Start the equipment's testing program and scan, collect, and detect each test point on the meat according to the preset parameters. Repeat the test 2-3 times for each test point to avoid random errors from a single test. During the test, near-infrared spectroscopy is used. The spectral probe is aligned with the test point, and diffuse reflection or transmission scanning is activated. The scanning range covers the target wavelength, and the spectral curve is recorded. Then, AI vision inspection is performed using a camera. An industrial camera collects images of the meat test surface. At the same time, color sensors and texture sensors are used to record visual features such as the color, texture, and intramuscular fat distribution of the meat. Step 4: Data Acquisition. The equipment automatically collects the raw data from each detection point, automatically transmits the data to the equipment's terminal or computer, saves it in a standardized data format, and preprocesses the data to remove abnormal data. Step 5: Result determination. Based on national or industry beef and mutton quality standards and testing requirements, the analyzed data are comprehensively determined, and the meat products are classified into four grades: superior, first-class, qualified, and unqualified.
