[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: a meat freshness detection device, including a fixed plate 1. The lower surface of the fixed plate 1 is evenly provided with a plurality of T-shaped grooves 2. The grooves 2 are divided into two groups, which are perpendicular to each other and interconnected. A plurality of sliders 3 are slidably arranged in the grooves 2. An air sensor 4 is installed on the lower surface of the slider 3. The detection end of the air sensor 4 is located at the bottom. The slider 3 can drive the air sensor 4 to move into any groove 2. By setting a plurality of crisscrossing grooves 2 on the fixed plate 1, the air sensor 4 can be flexibly moved to the corresponding position by sliding the slider 3 in the grooves 2. The position of each air sensor 4 can be flexibly adjusted according to the type, part and size of the meat to be detected, so as to specifically detect the freshness of the corresponding meat products. It can be applied to the freshness detection of different types of meat, greatly improving universality and flexibility of use.

[0020] Air sensor 4 preferably uses one or a combination of two of the following models: TGS2602 or TGS2603. TGS2602 is used to detect gases such as ammonia and hydrogen sulfide, while TGS2603 is used to detect gases such as trimethylamine and methyl mercaptan. These are all volatile organic compounds released when meat spoils, and these compounds can be used as indicators of meat freshness.

[0021] In a preferred embodiment, a rubber pad 12 is uniformly bonded to the lower surface of the fixing plate 1 near the slide groove 2. The upper surface of the air sensor 4 contacts the rubber pad 12, and the lower surface of the rubber pad 12 is provided with anti-slip texture. This allows the air sensor 4 to be fixed in the detection position after moving into place with the slider 3, and it will not slide automatically when not subjected to external force, thus improving the stability of the detection process and the accuracy of the detection results. At the same time, since the rubber pad 12 is bonded, it can be easily replaced with a new rubber pad 12 when it becomes worn and can no longer fix the position of the air sensor 4.

[0022] In a preferred embodiment, a plurality of color sensors 5 are uniformly arranged on the lower surface of the fixing plate 1. The detection end of the color sensor 5 is located at the bottom. The color sensor 5 can detect the color of the meat surface, thereby determining the freshness of the meat.

[0023] Both the color sensor 5 and the air sensor 4 are electrically connected to an external controller, preferably a commonly used microcontroller or PLC controller, such as an Arduino series microcontroller or a Siemens S7 series PLC controller. The controller has multiple built-in detection standard values ​​for different types of meat. When detecting the corresponding type of meat, its detection mode is set. The air sensor 4 detects whether the meat has volatile rancid gases and their concentration. The color sensor 5 detects the surface color of the meat and compares it with the built-in color standard, thereby intelligently detecting the freshness of the meat.

[0024] In a preferred embodiment, an electric push rod 6 is mounted on the upper surface of the fixed plate 1. The fixed end of the electric push rod 6 is mounted on a fixed frame above the meat conveyor belt, and the movable end of the electric push rod 6 is fixedly connected to the upper surface of the fixed plate 1. The electric push rod 6 is electrically connected to an external controller. The controller controls the electric push rod 6, the color sensor 5, and the air sensor 4 in a manner commonly used in the prior art. The electric push rod 6 can drive the fixed plate 1, the color sensor 5, and the air sensor 4 to move up and down, thereby adjusting the distance between the color sensor 5 and the air sensor 4 and the meat on the conveyor belt. This method is suitable for detecting meat of different thicknesses or heights.

[0025] During testing, the meat to be tested can be placed directly on the conveyor belt and moved below the color sensor 5 and the air sensor 4, or it can be placed in a container that matches the fixed plate 1. The container is then moved below the color sensor 5 and the air sensor 4 by the conveyor belt, and then the electric push rod 6 drives the fixed plate 1 and the color sensor 5 and the air sensor 4 to move downward into the container to test the meat.

[0026] The controller, electric actuator 6, color sensor 5, and air sensor 4 used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, control methods, and circuit connections are all well-known technologies and will not be described in detail here.

[0027] In a further preferred embodiment, a hinge seat 10 is provided between the upper surface of the color sensor 5 and the fixing plate 1. The angle of the detection end of the color sensor 5 can be adjusted through the hinge seat 10, thereby detecting the color freshness of different sides or angles of meat, further improving the flexibility of use.

[0028] Furthermore, the pin end of the hinge seat 10 is provided with an external thread, and a fastening nut 11 is threadedly connected to the external thread. By loosening the fastening nut 11, the color sensor 5 can be rotated at an angle. After rotating to the correct position, tightening the fastening nut 11 again can fix the angle of the color sensor 5. Adjustment is convenient and fixation is simple.

[0029] An optional technical solution is that the lower surface of the fixing plate 1 is provided with a T-shaped circular groove, and a rotating seat 9 is rotatably arranged in the circular groove. The rotating seat 9 is shaped to match the T-shaped circular groove. A hinge seat 10 is arranged on the lower surface of the rotating seat 9. The hinge seat 10 and the color sensor 5 can be rotated through the rotating seat 9. With the rotation of the hinge seat 10, the orientation of the detection end of the color sensor 5 at each position can be flexibly adjusted, thereby detecting the color freshness of different types or sizes of meat at various angles and surfaces, further improving the universality of detection.

[0030] Optionally, the top of the slider 3 is provided with a conductive head 7 connected to the air sensor 4, and a power receiving rod 8 corresponding to the conductive head 7 is fixedly provided in the slide groove 2. The air sensor 4 is electrically connected to the power receiving rod 8 through the conductive head 7 and is powered by the power receiving rod 8, so that the air sensor 4 can be energized and connected to the controller when it moves to any position in the slide groove 2, avoiding problems such as messy and tangled wiring. The way the air sensor 4 is connected to the power receiving rod 8 through the conductive head 7 and energized is similar to the principle of the trolleybus in the prior art, and a corresponding insulation protection device is provided.

[0031] In addition, the power supply for the air sensor 4 can also be achieved by setting wires or by embedding a battery in the slider 3 and a wireless transmission module connected to the controller.
