Description

Technical Field

[0001] The utility model relates to the technical field of meat detection equipment, and more specifically, to an online meat quality detection system. Background Art

[0002] Livestock and poultry meat is prone to spoilage during processing and distribution, resulting in waste and even food safety incidents. Therefore, quality testing and monitoring are crucial. While traditional physical and chemical methods for meat quality testing, such as Kjeldahl nitrogen determination and liquid chromatography, are widely used and accurate, they suffer from delayed results and inability to perform online, making them inadequate for the increasingly pressing technological transformation and upgrade needs of the meat industry. Near-infrared (NIR) detection, due to its non-destructive, rapid, pollution-free, and non-destructive nature, and its ability to perform online, has gained widespread application in food quality analysis, process monitoring, and biometrics.

[0003] For example, the invention patent with publication number CN117929263A discloses a meat quality detection device, a meat quality detection method and an electronic device, which includes a dark box arranged at the upper end of a main body bracket, in which a position sensor, an image acquisition module, a light source generating module and a processor for meat detection are arranged; in the above patented technology, the two sides of the main body bracket are connected to the two sides of a conveying module for conveying meat samples to be detected, and the width of the main body bracket is not adjustable. In actual applications, the widths of different meat processing lines are different. In the above patented technology, since the size of the main body bracket is fixed, the size of the dark box cannot be adjusted according to the width of the line. This limitation significantly reduces the scope of application of the patented technology and limits its promotion and wide application in the market. Utility Model Content

[0034] like Figures 1 to 4 As shown, the utility model provides a meat quality online detection system, which includes a meat quality online detector bracket, which is arranged on a meat processing line, and the detector bracket includes:

[0035] The housing 1 is provided with a detector body corresponding to the conveyor belt 52 of the assembly line;

[0036] Two threaded sleeves 31 are spaced apart at the bottom of the housing 1 along the width direction of the assembly line; each threaded sleeve 31 extends along the width direction of the assembly line;

[0037] Two threaded rods 32, one threaded rod 32 is provided for each threaded sleeve 31, one end of each threaded rod 32 is spirally rotated and sleeved in the corresponding threaded sleeve 31, and the other end extends horizontally outward along the width direction of the assembly line;

[0039] Two mounting plates are respectively arranged on both sides of the frame 51 of the assembly line. Each mounting plate is arranged horizontally and connected to the side of the frame 51 of the assembly line. Each mounting plate is a metal plate adapted to the magnet on the same side.

[0040] In the above technical solution, the utility model provides an online meat quality detection system, which includes an online meat quality detector bracket, which is installed at the upper end of the meat processing line in the slaughterhouse. The line includes a conveyor belt 52 for conveying meat and a frame 51 for supporting the conveyor belt. The detector bracket includes a shell 1, on which is provided a detector body for detecting meat. The detector body corresponds to the conveyor belt 52 of the line. To be precise, the probe of the detection element of the detector body is located directly above the conveyor belt, ensuring that the detection element of the detector body can act on the meat on the conveyor belt. In order to realize the detection of meat quality, two threaded sleeves 31 are arranged at intervals at the bottom of the shell 1 along the width direction of the assembly line (the direction of movement of the conveyor belt is the length direction of the assembly line, and the direction perpendicular to the direction of movement of the conveyor belt is the width direction of the assembly line). The axis of each threaded sleeve 31 extends along the width direction of the assembly line, and the inner wall of each threaded sleeve 31 is provided with an internal thread; each threaded sleeve 31 is correspondingly provided with a threaded rod 32, one end of the threaded rod 32 is spirally rotated and sleeved in the corresponding threaded sleeve 31, and the threaded rod 32 is provided with an external thread that adapts to the internal thread of the threaded sleeve 31. 1 is connected to the housing 1 so as to be fixed, and the threaded rod 32 rotates relative to the threaded sleeve 31. Under the action of the spiral rotation connection between the internal thread and the external thread, the threaded rod 32 moves linearly relative to the threaded sleeve 31 along the width direction of the assembly line. A movable plate 4 is correspondingly provided at the other end (the end facing outward) of each threaded rod 32. The other end of the threaded rod 32 is rotationally connected to the corresponding movable plate 4 through a bearing. Each movable plate 4 is slidably connected to the housing 1 along the width direction of the assembly line. The threaded rod 32 rotates relative to the corresponding threaded sleeve 31, and can drive the corresponding movable plate 4 while moving along the width direction of the assembly line. It moves along the width direction of the assembly line, and then the distance between the two movable plates 4 can be adjusted according to the width of the assembly line, so that the distance between the two movable plates 4 is adapted to the width of the assembly line; further, each movable plate 4 is correspondingly provided with a mounting plate, and each mounting plate is detachably connected to the frame 51 of the assembly line, and specifically can be connected by a locking nut, and the mounting plate is set to a metal material that can be magnetically attracted by a magnet, such as iron, and a magnet is set at the bottom of the movable plate 4, and the movable plate 4 and the mounting plate are connected by magnetic attraction, which is convenient and quick to install and disassemble, while improving the stability of the installation of the detection device and the frame 51 of the assembly line.

[0041] The utility model is provided with two movable plates 4 that can move along the width direction of the assembly line at the bottom of the shell 1 with the detector body. The position of each movable plate 4 can be adjusted by rotating the threaded rod 32, and then the spacing between the two movable plates 4 can be adjusted, so that it is suitable for the detection of meat products in assembly lines of different widths. Furthermore, the meat quality online detection system of the utility model and the assembly line frame 51 have a simple and easy-to-operate loading and unloading structure. Specifically, a magnet is provided at the bottom of the movable plate 4, and a metal mounting plate adapted to the two magnets is provided. During installation, existing technical means such as locking nuts are used to install the mounting plate on the side of the assembly line frame 51, and then the bottom-opening box composed of the shell 1 and the two movable plates 4 is placed from top to bottom on the upper end of the assembly line, and the installation and fixation are achieved by magnetic attraction between the magnet at the bottom of the movable plate 4 and the corresponding mounting plate. The entire installation process is simple and easy to operate. When disassembly is required, the bottom-opening box composed of the shell 1 and the two movable plates 4 can be lifted up with force, and the locking nuts can be removed to remove the mounting plate from the assembly line frame. The disassembly operation is also simple.

[0042] In actual application: according to the width of the assembly line where the meat to be inspected is located, the spacing between the two movable plates 4 is adjusted. The specific adjustment method is to rotate the threaded rod 32. Under the action of the spiral rotation connection between the threaded rod 32 and the threaded sleeve 31, the threaded rod 32 moves in a straight line, thereby driving the movable plate 4 to move in a straight line, and adjust the spacing between the two movable plates 4 to be greater than the width of the conveyor belt 52 of the assembly line (to ensure that the movable plate 4 does not interfere with the normal operation of the conveyor belt 52 of the assembly line) and not greater than the outer edge width of the frame 51 of the assembly line (to ensure that the bottom of the movable plate 4 can be placed on the frame 51 of the assembly line); then a horizontal metal mounting plate is installed on both sides of the frame 51 of the assembly line corresponding to the detection position. The locking nut in the prior art can be used, or other methods can be used. As long as the mounting plate is detachably connected to both sides of the frame, the housing 1 and the two movable plates 4 are formed into an integral structure. The box body is moved to the upper end of the conveyor belt 52 of the assembly line, and the magnet on the movable plate 4 is magnetically attracted to the corresponding mounting plate to realize the installation of the meat quality online detection system.

[0043] In another technical solution, the meat quality online detection system further includes:

[0044] a stepper motor 33 disposed on the housing 1 , wherein the output shaft of the stepper motor 33 extends horizontally along the width direction of the assembly line;

[0045] A first pulley 34 is fixedly and coaxially sleeved on the output shaft of the stepping motor 33;

[0046] A second pulley 35 is provided between the two threaded sleeves 31 and is located directly below the first pulley 34. The second pulley 35 and the first pulley 34 are linked via a transmission belt 36;

[0047] Two telescopic rods 37 are provided, and one telescopic rod 37 is provided corresponding to one threaded rod 32. One end of each telescopic rod 37 is connected to the central axis of the second pulley 35, and the other end extends outward along the width direction of the assembly line, and passes through one end of the corresponding threaded sleeve 31 to extend to the inside of the threaded sleeve 31 and is coaxially fixedly connected to the corresponding threaded rod 32.

[0048] In the above technical solution, the present invention further discloses a driving mechanism for driving the two threaded rods 32 to rotate synchronously, which specifically includes a stepping motor 33 provided on the housing 1, and the output shaft of the stepping motor 33 extends horizontally along the width direction of the assembly line, and a first pulley 34 is coaxially fixed on the output shaft of the stepping motor 33, and a second pulley 35 is provided between the two threaded sleeves 31, which is arranged parallel to the first pulley 34 and is located directly below the first pulley 34, and the first pulley 34 and the second pulley 35 are linked by a transmission belt 36, so that starting the stepping motor 33 and driving the output shaft of the stepping motor 33 to rotate can drive the rotation of the first pulley 34 and the second pulley 35, and the two ends of the central axis of the second pulley 35 are respectively coaxially connected to the other end of the two threaded rods 32 through a telescopic rod 37, and each telescopic rod 37 is formed by a freely retractable inner and outer sleeve, and one end of each telescopic rod 37 is connected to the second pulley 3 5 is coaxially fixedly connected with the central axis, and the other end extends horizontally outward along the width direction of the assembly line, passes through one end of the threaded sleeve 31 (the inner end, the diameter of the telescopic rod 37 is smaller than the diameter of the threaded sleeve 31, and the threaded sleeve 31 does not limit the telescopic rod 37 from extending and rotating around its own axis) to the interior of the threaded sleeve 31 and is coaxially fixedly connected with the other end of the corresponding threaded rod 32. By setting the telescopic rod 37, the two threaded rods 32 are linked to the central axis of the second pulley 35, so that the rotation of the second pulley 35 can synchronously drive the rotation of the two threaded rods 32. At the same time, the two telescopic rods 37 are extended and retracted as the threaded rods 32 move linearly along the width direction of the assembly line. The external threads of the two threaded rods 32 rotate in opposite directions, and the internal threads of the two threaded sleeves 31 rotate in the same direction, so that the two threaded rods 32 rotate synchronously in the same direction, and can move synchronously toward each other (approaching each other) or away from each other (moving away from each other) along the width direction of the assembly line.

After reflection from the surface of the meat, its spectral information is captured to analyze the chemical composition and structural characteristics of the meat. At the same time, the high-resolution camera captures the real-time image of the meat, while the RFID reader extracts basic information of the sample.).
