Description

Technical Field

[0001] This invention belongs to the field of livestock slaughtering and raw meat processing, and specifically relates to a CT detection device for a pork slaughtering production line. Background Technology

[0002] I. Development of the Pork Industry and the Needs for Quality and Safety As the meat consumed by Chinese residents, pork has become increasingly important. With the upgrading of consumption and the continuous improvement of the food safety supervision system, the market's quality requirements for pork products have shifted from "qualified" to "high-quality, safe, and traceable". Among them, the slaughtering and processing link is the key node for pork from the breeding end to the consumer end, and its testing efficiency and accuracy directly determine the safety level of the end product.

[0003] In slaughtering and processing lines, pork undergoes multiple processes, including carcass inspection, visceral inspection, parasite detection, and foreign object screening. Traditional testing methods primarily rely on manual sensory inspection, supplemented by sampling laboratory testing. This approach suffers from issues such as high subjectivity, low efficiency, and limited coverage. In large-scale slaughterhouses, production lines can operate at speeds of 1-2 pigs per minute, making it difficult for manual inspection to achieve comprehensive, thorough coverage and increasing the risk of missed detections. While laboratory sampling testing offers high accuracy, its long testing cycle (typically several hours to days) fails to meet the production line's need for "real-time detection and immediate decision-making," making it difficult to address unexpected quality issues.

[0004] II. Limitations of Existing Pork Production Line Testing Technologies The automated testing technologies currently used in the industry still have significant technical bottlenecks and cannot fully adapt to the complex scenarios and high-efficiency requirements of pork slaughtering production lines. Specific shortcomings are reflected in the following aspects: Traditional physical inspection techniques lack precision: While the X-ray inspection equipment widely used in existing production lines can perform preliminary screening for metal foreign objects, bone abnormalities, etc., it is limited by the two-dimensional imaging principle and cannot clearly present the three-dimensional structure inside pork. The recognition rate for low-density defects such as tiny parasites (such as cysticercosis in pigs, which is only 2-5mm in diameter) and tissue lesions (such as local inflammation and abscesses) is less than 60%, and it is easily affected by differences in meat density (such as uneven distribution of fat and lean meat), resulting in a high false detection rate.

[0005] Poor compatibility between testing and production lines: Current testing equipment mainly adopts a horizontal structure, requiring manual handling of pork carcasses or cut meat to the testing platform. This makes it impossible to directly connect with the production line conveyor chain, increasing manual handling costs, disrupting production line continuity, and causing the testing process to become a "bottleneck" for improving production line efficiency.

[0006] Lack of multi-dimensional testing capabilities: Pork quality testing needs to cover multiple dimensions such as "lean meat percentage, moisture content, foreign objects, parasites, and tissue lesions". Existing technologies are mostly single-function devices (such as standalone metal detectors and moisture meters), requiring multiple testing stations to be set up in the production line, which prolongs the processing flow and time. Moreover, the data from different devices cannot be linked in real time, making it difficult to form a complete quality testing report, which is not conducive to subsequent traceability and analysis.

[0007] Low level of intelligence and data: Traditional testing equipment relies heavily on manual judgment of test results and lacks the ability to connect with production line MES (Manufacturing Execution System) and ERP (Enterprise Resource Planning) systems. It cannot realize automatic uploading, analysis and early warning of test data, which makes it difficult to meet the development needs of modern slaughtering enterprises for "digital management and intelligent decision-making". Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a CT inspection device for pork slaughtering production lines, which can solve the aforementioned problems.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a CT detection device for a pork slaughtering production line, comprising a base, a drive assembly, a rotary support assembly, a rotating seat, an X-ray source assembly, and a detector assembly; The rotating seat is rotatably mounted on the base via the rotary support assembly. The drive assembly is used to drive the rotating seat to rotate. The detector assembly and the radiation source assembly are respectively disposed on both sides of the rotating seat, and the detector assembly and the radiation source assembly are disposed opposite to each other.

[0010] Preferably, the base includes a platform, and the bottom of the platform is provided with a support pad and an auxiliary support pad.

[0011] Preferably, shock absorbers are provided between the platform and the support pad, and between the platform and the auxiliary support pad.

[0012] Preferably, the slewing support assembly includes a first adapter plate and a slewing support ring. The first adapter plate is disposed on the base, the slewing support ring is rotatably disposed on the first adapter plate, and the rotating seat is fixed to the slewing support ring.

[0013] Preferably, the drive assembly includes a motor and a gear, the gear being rotatably mounted on the first adapter plate, the rotary support ring having external teeth, the rotary support ring meshing with the gear through the external teeth, and the motor being used to drive the gear to rotate.

[0014] Preferably, the device further includes a sewage discharge assembly, which includes a drainage trough, a sewage tray, a first drainage pipe, and a second drainage pipe. The drainage trough has a ring structure and is disposed on the first adapter plate. The drainage trough is located inside the rotating support ring. The sewage tray is disposed on the rotating seat. The top end of the first drainage pipe is connected to the sewage tray, and the bottom end of the first drainage pipe extends through the rotating seat to above the drainage trough. The second drainage pipe is connected to the drainage trough.

[0015] Preferably, the rotating base includes a second adapter plate, a rotating base frame, and a mounting base plate. The second adapter plate is connected to the mounting base plate through the rotating base frame, and the detector assembly and the radiation source assembly are disposed on the mounting base plate.

[0016] Preferably, the device further includes a slip ring, a slip ring mounting plate is provided at the bottom end of the rotating seat frame, the slip ring rotor is connected to the slip ring mounting plate, and the slip ring stator is disposed on the base.

[0017] Preferably, the radiation source assembly includes a radiation source mounting frame, a radiation source controller, and a radiation generator. The radiation source mounting frame is disposed on the rotating base, and the radiation source controller and the radiation generator are both disposed on the radiation source mounting frame. The radiation source controller is electrically connected to the radiation generator.

[0018] Preferably, the detector assembly includes a detector mounting frame and a detector. The detector mounting frame is disposed on the rotating base, and the detector is disposed on the detector mounting frame. The detector is disposed opposite to the radiation generator.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Higher detection accuracy and more comprehensive detection content, realizing multiple functions of one device. In existing pork production lines, various tests are relatively independent. Currently, widely used X-ray inspection equipment is mainly used for metal foreign object sampling and bone screening, but it cannot detect the quality and internal three-dimensional structure of pork, nor can it identify tiny parasites or tissue lesions. This device not only solves this problem, but also uses 360° scanning to build a three-dimensional structure of the pig carcass, accurately revealing the location of abnormalities in the pork. At the same time, it analyzes the fat and lean meat ratio of pork based on different densities and detects the moisture content of pork. It can replace multiple testing steps and significantly optimize the pork production testing process.

[0020] 2. Innovative testing methods enable simultaneous pork production and testing, with non-destructive testing improving efficiency. Traditional pork testing mainly relies on laboratory testing. Some automated testing methods require separate testing lines, which necessitate the pre-cutting and sorting of pork carcasses. The testing cycle can last from several hours to several days. This device combines pork testing with production and is a non-destructive testing method. The testing time for a single pig is reduced to less than 1 minute, significantly reducing the testing cycle and improving testing efficiency.

[0021] 3. Significantly increase the coverage of pork testing, provide timely feedback on testing information, and improve the safety and quality of pork production. Traditional pork testing primarily relies on sampling, which is prone to missed detections and allows abnormal pork to enter the market, posing significant safety risks. When abnormalities are detected in traditional methods, pork production is typically slowed down, the testing scope expanded, and pork already on the market recalled – a process that is not only risky for food safety but also time-consuming and labor-intensive. This device achieves full coverage of pork testing across the slaughterhouse production line, providing timely feedback on abnormalities and preventing the aforementioned problems.

[0022] 4. Optimize the pork sorting process in pig production to reduce labor costs. Traditional pork production lines rely mainly on manual subjective judgment to classify pork according to its quality, which is prone to errors and inefficient. This device can digitize pork information and classify pork accurately and automatically according to scientific standards, improving the accuracy and efficiency of classification judgment.

[0023] 5. High stability, significantly reducing artifacts caused by device vibration. The internal crystal structure of the marble platform can absorb 30%-40% of the vibration generated by the movement, increase the support of the shock absorber, further enhance the shock absorption capacity of the base, greatly increase the stability of the device's movement, reduce artifacts caused by vibration, and increase scanning accuracy.

[0026] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0027] This embodiment provides a CT detection device for a pork slaughtering production line, including a base 1, a drive assembly 2, a rotary support assembly 3, a rotating seat 4, an X-ray source assembly 6, and a detector assembly 7; The rotating seat 4 is rotatably mounted on the base 1 via the rotary support assembly 3. The drive assembly 2 is used to drive the rotating seat 4 to rotate. The detector assembly 7 and the radiation source assembly 6 are respectively mounted on both sides of the rotating seat 4, with the detector assembly 7 and the radiation source assembly 6 positioned opposite each other.

[0028] For example, see Figure 1 The device provided in this embodiment is installed below the conveyor line A of the pig slaughtering production line. The center of the line connecting the detector assembly 7 and the radiation source assembly 6 is located directly below the conveyor line A, and the center of the rotary support assembly 3 is also located directly below the conveyor line A.

[0029] In its initial (static) state, the base 1 is perpendicular to the long side of the conveyor line A, with the X-ray source assembly 6 and detector assembly 7 positioned opposite each other on either side of conveyor line A. Conveyor line A transports the test object B (such as pork) to the detection position (between X-ray source assembly 6 and detector assembly 7), triggering a pause signal on the conveyor line, and test object B remains at the detection position. Drive assembly 2 then begins operation, driving the rotating seat 4 to rotate. X-ray source assembly 6 and detector assembly 7 rotate synchronously with the rotating seat 4. During this process, the device transitions from static to dynamic. Once the rotation reaches a constant speed, X-ray source assembly 6 emits X-rays to scan the test object, and detector assembly 7 receives the scan signal. After completing a 360° scan of the test object, the rotation ends, and all components return to their initial positions. Conveyor line A then restarts, transporting test object B out of the detection area. The scan signal is synchronously transmitted to the analysis computer for imaging analysis, and the device continues operation, performing cyclic scanning and detection.

[0030] In summary, the device provided in this embodiment can construct a three-dimensional structure of a pig carcass through 360° scanning, accurately identifying abnormal locations in the pork. Simultaneously, it analyzes the fat and lean meat ratios based on density differences and detects the moisture content of the pork. This can replace multiple testing steps, significantly optimizing the pork production testing process. Pork testing and production are performed simultaneously and non-destructively, reducing the testing time per pig to less than one minute, significantly shortening the testing cycle and improving efficiency. It achieves full coverage of pork testing across the slaughterhouse production line, providing timely feedback on abnormal information. By digitizing pork information, it enables precise and automated classification of pork according to scientific standards, improving the accuracy and efficiency of classification judgment.

[0031] Based on the above technical solution, in the technical solution provided in this embodiment, the base 1 includes a platform 104, and the bottom of the platform 104 is provided with a support pad 101 and an auxiliary support pad 102. Shock absorbers 103 are provided between platform 104 and support pad 101, and between platform 104 and auxiliary support pad 102; For example, see Figure 2-3 The support pad 101 and auxiliary support pad 102 can be installed on the ground using expansion bolts, and together they form a support base array. A shock absorber 103 can be installed between the support pad 101 and the platform 104, and a shock absorber 103 is also installed between the auxiliary support pad 102 and the platform 104. The shock absorbers 103 can support the platform 104 and absorb vibrations generated during the operation of the device, keeping the platform 104 level.

[0032] For example, platform 104 can be a marble platform. The internal crystal structure of the marble platform can absorb 30%-40% of the vibration generated by the movement. Together with the shock absorber 103, it further enhances the shock absorption capability of the base 1, greatly increases the stability of the device's movement, reduces artifacts caused by vibration, and increases scanning accuracy.

[0033] In the technical solution provided in this embodiment, the slewing support assembly 3 includes a first adapter plate 301 and a slewing support ring 302. The first adapter plate 301 is disposed on the base 1, and the slewing support ring 302 is rotatably disposed on the first adapter plate 301. The rotating seat 4 is fixed to the slewing support ring 302. For example, see Figure 2-3 The first adapter plate 301 is fixedly installed on the upper surface of the platform 104. The slewing support ring 302 is rotatably mounted on the first adapter plate 301 via bearings, and the rotating seat 4 is fixed to the top of the slewing support ring 302. The slewing support ring 302 can rotate freely on the first adapter plate 301 and drive the rotating seat 4 to rotate synchronously, and the axis of the slewing support ring 302 is arranged vertically.

[0034] In the technical solution provided in this embodiment, the drive component 2 includes a motor 201 and a gear 206. The gear 206 is rotatably mounted on the first adapter plate 301. The rotary support ring 302 is provided with external teeth. The rotary support ring 302 meshes with the gear 206 through the external teeth. The motor 201 is used to drive the gear 206 to rotate. For example, see Figure 2 , Figure 3 , Figure 6 The motor 201 can be a servo motor, and it is mounted on the bottom of the platform 104. A central shaft is coaxially fixed to the bottom of the gear 206. The central shaft of the gear 206 is rotatably mounted on the first adapter plate 301 via a bearing housing 204 and a deep groove ball bearing. The power output end of the motor 201 is connected to the central shaft of the gear 206 via a reducer 202, which can be a right-angle planetary reducer. Both the first adapter plate 301 and the platform 104 have through holes for the reducer 202 and the central shaft to pass through. External teeth are fixed circumferentially on the outer wall of the rotary support ring 302, and these teeth mesh with the gear 206. Thus, the motor 201 can drive the gear 206 to rotate, which in turn drives the rotary support ring 302 to rotate. The reducer 202 reduces the rotation speed, preventing excessive speed.

[0035] For example, see Figure 2 The motor 201 and the reducer 202 can be covered with a protective cover 203. The protective cover 203 can play a protective role and improve the stability and service life of the device.

[0036] The technical solution provided in this embodiment also includes a sewage discharge component 9, which includes a drainage trough 901, a sewage tray 902, a first drainage pipe 903, and a second drainage pipe 904. The drainage trough 901 has a ring structure and is disposed on the first adapter plate 301. The drainage trough 901 is located inside the rotary support ring 302. The sewage tray 902 is disposed on the rotating seat 4. The top end of the first drainage pipe 903 is connected to the sewage tray 902, and the bottom end of the first drainage pipe 903 extends through the rotating seat 4 to the top of the drainage trough 901. The second drainage pipe 904 is connected to the drainage trough 901. For example, see Figure 3-5 The drainage trough 901 is installed on the first adapter plate 301, and the sewage tray 902 is installed on the rotating seat 4. The rotating seat 4 is provided with a through hole for the first drainage pipe 903 to pass through, so that the bottom end of the first drainage pipe 903 can extend to the top of the drainage trough 901. The sewage tray 902, the drainage trough 901, and the rotating support ring 302 are all coaxial.

[0037] The wastewater tray 902 is used to collect wastewater dripping from the sample. When the rotating support ring 302 is driven to rotate by the motor 201, the rotating seat 4 rotates, which in turn drives the wastewater tray 902 to rotate. Simultaneously, the first drain pipe 903 rotates along the drain trough 901, allowing wastewater in the wastewater tray 902 to flow into the drain trough 901 through the first drain pipe 903, preventing it from flowing outwards. When the drain trough 901 does not rotate, the wastewater within it can be drained away through the second drain pipe 904.

[0038] In the technical solution provided in this embodiment, the rotating seat 4 includes a second adapter plate 401, a rotating seat frame 402, and a mounting base plate 403. The second adapter plate 401 and the mounting base plate 403 are connected through the rotating seat frame 402. The detector assembly 7 and the radiation source assembly 6 are disposed on the mounting base plate 403. For example, see Figure 2 , Figure 5 The second adapter plate 401 has an assembly hole at its bottom end that matches the rotary support ring 302. The second adapter plate 401 is fixedly installed on the top of the rotary support ring 302 through this assembly hole. The rotating seat frame 402 can be an aluminum profile frame. The rotating seat frame 402 is fixed on the second adapter plate 401, and the mounting base plate 403 is fixed on the rotating seat frame 402, and the mounting base plate 403 is kept horizontal. The interior of the rotating seat frame 402 is hollow and can be used for wiring. The mounting base plate 403 has mounting holes for installing the detector assembly 7 and the radiation source assembly 6. The mounting base plate 403 has multiple sets of mounting holes evenly spaced along its length, so that different mounting holes can be selected for installing the detector assembly 7 and the radiation source assembly 6 according to different detection distance requirements.

[0039] The technical solution provided in this embodiment also includes a slip ring 5. The bottom end of the rotating seat frame 402 is provided with a slip ring mounting plate 404. The rotor of the slip ring 5 is connected to the slip ring mounting plate 404, and the stator of the slip ring 5 is set on the base 1. For example, see Figure 5 A slip ring mounting plate 404 is fixedly provided at the bottom of the rotating seat frame 402. When the second adapter plate 401 is installed at the top of the rotary support ring 302, the slip ring mounting plate 404 is located inside the drainage groove 901. At the same time, the first adapter plate 301 and the platform 104 are provided with through holes for the slip ring 5 to pass through, so that the slip ring 5 does not interfere with the drainage groove 901, the first adapter plate 301, the platform 104, etc.

[0040] The rotor of slip ring 5 can rotate together with slip ring mounting plate 404 and rotating seat frame 402, while the stator of slip ring 5 is fixed to platform 104. In this way, the electrical signals of the rotating structure of the device (such as X-ray source assembly 6 and detector assembly 7) can be connected to external fixed cables through slip ring 5 to realize the normal transmission of electrical signals in motion, avoiding phenomena such as wire tangling, which would cause the device to malfunction.

[0041] In the technical solution provided in this embodiment, the radiation source assembly 6 includes a radiation source mounting frame 601, a radiation source controller 603, and a radiation generator 605. The radiation source mounting frame 601 is mounted on the rotating seat 4. The radiation source controller 603 and the radiation generator 605 are both mounted on the radiation source mounting frame 601. The radiation source controller 603 and the radiation generator 605 are electrically connected. For example, see Figure 2 The X-ray source mounting frame 601 can be an aluminum profile frame, and it is installed through the mounting holes in the mounting base plate 403. The X-ray source controller 603 is fixedly mounted on the X-ray source mounting frame 601 through the controller mounting plate 602, and the X-ray generator 605 is fixedly mounted inside the X-ray source mounting frame 601 through the X-ray generator mounting plate 604. Furthermore, the X-ray source controller 603 and the X-ray generator 605 are arranged in three sets at even intervals along the vertical direction, forming a X-ray source array, effectively increasing the detection range.

[0042] The X-ray source mounting frame 601 can be covered with a protective cover, which is made of sheet metal and carbon fiber plate, providing protection. The cover has windows to allow X-rays to pass through and facilitate manual operation of the X-ray source controller 603. A relay box 8 can be installed on one side of the protective cover. The relay box 8 contains electrical components for relaying various electrical signals and rotates synchronously with the mounting base 403. The connecting wires of the X-ray source controller 603 and the X-ray generator 605 can pass through the mounting base 403, enter the rotating seat frame 402, and then connect to the slip ring 5. This ensures the connecting wires are completely enclosed, preventing external interference and extending the lifespan of the device. In the technical solution provided in this embodiment, the detector assembly 7 includes a detector mounting frame 701 and a detector 704. The detector mounting frame 701 is mounted on the rotating seat 4, and the detector 704 is mounted on the detector mounting frame 701. The detector 704 is positioned opposite to the radiation generator 605. For example, see Figure 2 The detector mounting frame 701 can be an aluminum profile frame, and it is mounted through the mounting holes in the mounting base plate 403. A detector mounting plate 702 is mounted on the outside of the detector mounting frame 701. Detectors 704 are fixed to the detector mounting plate 702 via detector fixing plates 703. Three sets of detectors 704 are evenly spaced vertically, and each detector 704 corresponds one-to-one with a radiation generator 605. The detectors 704 and their corresponding radiation generators 605 are positioned opposite each other to receive radiation and form detection image signals.

[0043] The detector mounting frame 701 can be covered with a protective cover, which is made of sheet metal and carbon fiber plate, providing protection. The cover has windows to allow radiation to pass through. A relay box 8 can be installed on one side of the protective cover. The relay box 8 houses electrical components used to relay various electrical signals and rotates synchronously with the mounting base plate 403. A dehumidifier 706 is installed inside the detector mounting frame 701 via a dehumidifier mounting plate 705. The dehumidifier 706 dehumidifies the interior, preventing excessive humidity from affecting the performance of the detector and other electrical components. The connecting wires between the detector 704 and the dehumidifier 706 can pass through the mounting base plate 403, enter the rotating seat frame 402, and then connect to the slip ring 5. This ensures the connecting wires are completely enclosed, preventing external interference and extending the device's service life.
