Description

Technical Field

[0001] The present invention relates to the field of food detection, in particular to a food detection device for food production. Background Art

[0002] In the food production industry, food safety testing is crucial. Drawing on theories and techniques from physics, chemistry, and biology, and based on national technical indicators, it conducts quality inspections on food raw materials, semi-finished products, and finished products. This testing encompasses sensory, nutritional, additive, and hazardous substance testing, making it a key means of ensuring food safety. Currently, a variety of food testing technologies and devices are available on the market. Chromatography, for example, is used to separate and analyze food components and is widely used in pesticide and drug residue detection. Spectroscopic analysis, based on the interaction between matter and electromagnetic radiation, is a non-destructive and rapid method. However, existing food testing devices have exposed numerous problems in actual use. For one thing, some devices use relatively fixed sampling locations, making it difficult to comprehensively and randomly cover the entire food. This can result in test results that may not accurately reflect the true quality of the food, affecting the accuracy of the test results. Furthermore, the sampling process of most devices relies on manual operation. Due to differences in technique and strength between operators, human error can easily be introduced, affecting the reliability of test results and even causing substandard food to enter the market, threatening consumer health and safety.

[0003] Therefore, it is of great practical significance to develop a food testing device that is simple in structure, easy to use, can achieve random sampling to ensure detection accuracy, and has a high degree of automation to reduce labor intensity and human errors. Summary of the Invention

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0020] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0022] Example 1: Please refer to Figure 1 and Figure 2 A food testing device for food production includes a device base 1, on which is disposed a rotating tray assembly 2. The food to be tested is placed on top of the tray assembly 2. A telescopic drive rod 3 is fixedly connected to the top of the device base 1. The telescopic drive rod 3 can be an electric telescopic rod or other structural member with a telescopic drive force. The telescopic drive rod 3 is located on the side of the tray assembly 2. A transverse guide sleeve 4 is fixedly connected to the top of the telescopic drive rod 3. A telescopic guide rod 5 that can be locked in position is slidably connected to the transverse guide sleeve 4. A sampling assembly 6 is fixedly connected to the end of the telescopic guide rod 5. Sampling and sample collection are completed during the up-and-down flipping process of the sampling assembly 6.

[0023] Before using the device, you need to debug the device first. After power on, place the food sample to be tested on the tray assembly 2. The tray assembly 2 will drive the food to rotate during rotation, so that samples can be randomly taken on the surface of the food during sampling. During sampling, the sampling assembly 6 flips up and down, collects food samples after flipping down, and collects the collected samples after flipping up.

[0024] See also Figure 6 The tray assembly 2 includes a support shaft 7 rotatably connected to the device base 1. An outer tray 8 is fixedly connected to the top of the support shaft 7. An inner tray 9 is rotatably connected to the inner side of the outer tray 8. The bottom of the support shaft 7 is in transmission connection with a drive unit 10. The drive unit 10 includes a drive motor 11. A driving dial 12 is fixedly connected to the rotor of the drive motor 11. A driven sheave 13 is fixedly connected to the bottom of the support shaft 7. The driving dial 12 and the driven sheave 13 are cooperatively connected. Rotation of the drive motor 11 drives the driving dial 12, which in turn rotates the driven sheave 13, thereby causing the support shaft 7 to intermittently rotate. The intermittent rotation of the food sample results in a more random position during sampling. The inner tray 9 and the outer tray 8 are rotatably connected, resulting in low friction between them. Due to the low friction, although the outer tray 8 rotates, the inner tray 9 rotates relative to the outer tray 8 during food sampling. The food stops moving and only rotates with the outer tray 8 due to friction after sampling is complete.

[0025] A slide 14 is provided above the base 1 of the device. A slider 15 is slidably connected in the slide 14. A column 16 is fixedly connected to the slider 15. A sampling base 17 is fixedly connected to the top of the column 16. A locking bolt 18 for locking the position of the slider 15 is provided on the slider 15. The position of the sliding adjustment slider 15 is adjusted so that the position of the sampling base 17 connected to the slider 15 is adjusted. At the same time, the position of the telescopic guide rod 5 inside the transverse guide sleeve 4 needs to be adjusted accordingly so that the sampling assembly 6 can smoothly perform sampling and collect the sample. The purpose of adjusting the position is to make the sampling position more random. After using the device for a period of time, it can be adjusted. After the adjustment is completed, the position of the slider 15 is fixed by the locking bolt 18. At the same time, the position of the telescopic guide rod 5 also needs to be fixed. The telescopic guide rod 5 can also be fixed by a locking mechanism similar to the locking bolt 18.

[0026] Example 2: This example specifically discloses the following technical contents based on the previous example: Please refer to Figure 2 、 Figure 3 and Figure 5 The sampling assembly 6 includes a telescopic guide rod 5 whose end is rotatably connected to a sampling gear 19, a first-level rocker 20 is fixedly connected to the bottom of the sampling gear 19, and a second-level rocker 21 is rotatably connected to the bottom of the first-level rocker 20. The rotation direction of the second-level rocker 21 is perpendicular to the rotation direction of the first-level rocker 20. The second-level rocker 21 rotates in a vertical plane, and the bottom of the second-level rocker 21 is rotatably connected to two matching semicircular arc parts 22 through a spring 28 hinge. The two semicircular arc parts 22 are combined into a cylindrical shape under the action of the spring hinge, and also include a gear flipping unit 23 for driving the sampling gear 19 to flip.

[0027] The sampling assembly 6 includes a primary pendulum 20 and a secondary pendulum 21 that are rotatably connected together and connected via a sampling gear 19. During the rotation of the sampling gear 19, when the secondary pendulum 21 is vertically located below the primary pendulum 20, the telescopic drive rod 3 contracts, driving the semicircular arc-shaped member 22 at the bottom to move downward and insert into the food for sampling. Conversely, when the primary pendulum 20 swings upward, it drives the secondary pendulum 21 upward, and then the secondary pendulum 21 rotates sideways to remove the sample. The two semicircular arc-shaped members 22 form a cylindrical shape, which can cut the food after being inserted into the food, and then take out the food sample when pulled out. The flip unit 23 is used to enable the sampling gear 19 to flip during its up and down movement.

[0028] See also Figure 4 A lower blind groove 24 is formed on one end of the secondary rocker arm 21 facing the primary rocker arm 20, and an upper blind groove 25 is formed on one end of the primary rocker arm 20 facing the secondary rocker arm 21. The depth of the upper blind groove 25 is longer than the depth of the lower blind groove 24. A locking rod 26 is placed in the upper blind groove 25. When the secondary rocker arm 21 is located below the primary rocker arm 20, the locking rod 26 enters the lower blind groove 24, so that the secondary rocker arm 21 cannot rotate relative to the primary rocker arm 20. When the primary rocker arm 20 is located below the secondary rocker arm 21, the locking rod 26 is completely located in the upper blind groove 25.

[0029] When the secondary rocker arm 21 is located below the primary rocker arm 20, the locking rod 26 is located in the lower blind groove 24, and the upper end is located inside the primary rocker arm 20. At this time, relative rotation cannot be generated between the secondary rocker arm 21 and the primary rocker arm 20, and the downward moving telescopic drive rod 3 will drive the semicircular arc-shaped part 22 to penetrate into the food. When the primary rocker arm 20 swings to the top, since the locking rod 26 completely enters the upper blind groove 25, the secondary rocker arm 21 will rotate sideways, and the sampled food can be taken out for collection through external force.

[0030] See also Figure 5 The flip unit 23 includes a fixed slot 27 fixedly connected to the sampling base 17. A sliding rack 29 is connected to the fixed slot 27 via a spring 28. The sliding rack 29 meshes with the sampling gear 19. Limit blocks 30 are fixedly connected to both ends of the sliding rack 29. When the sampling gear 19 is restrained by the upper and lower limit blocks 30, the primary rocker 20 assumes a vertical position. The flip unit 23 is designed to achieve a 180° rotation range for the primary rocker 20. After the flip is completed, the sampling gear 19 is locked with the limit block 30 on the corresponding side, preventing further rotation. At this time, the primary rocker 20 will continue to move upward or downward in response to the extension or contraction of the telescopic drive rod 3. The spring 28 provides a reset force.

[0031] A side plate 31 is fixedly attached to the side of the sampling base 17 to prevent the secondary pendulum 21 from rotating outward. To further ensure the swing direction of the secondary pendulum 21, a magnet can be attached to the side of the side plate 31 opposite the secondary pendulum 21. Under the repulsive effect of the magnetic force, the secondary pendulum 21 can maintain its direction after rotation.

[0032] A collection tray 32 is also placed on the side of the sampling base 17. The sampling base 17 is provided with a collection unit 33 for moving the sample into the collection tray 32. The collection unit 33 includes a collection motor 34 fixedly connected to the sampling base 17. A knocking plate 35 is fixedly connected to the rotor of the collection motor 34. The knocking plate 35 is made of rubber. During the rotation of the knocking plate 35, the collected sample is knocked and dropped into the collection tray 32. The collection motor 34 rotates, driving the knocking plate 35 to rotate. Then, when the semi-circular arc-shaped member 22 moves to this position, the internal food sample enters the collection tray 32 under the action of external force. When the semi-circular arc-shaped member 22 is misaligned with the knocking plate 35, the semi-circular arc-shaped member 22 is reset under the action of the spring hinge.

[0033] Working Principle: The device requires debugging before use. After powering on, place a food sample on the tray assembly 2. The rotation of the tray drives the food, allowing the sampling assembly 6 to randomly collect surface samples during sampling. The sampling assembly 6 is rotatably connected to the secondary pendulum 21 via the primary pendulum 20, driven by the sampling gear 19. When the secondary pendulum 21 is vertically positioned below the primary pendulum 20, the telescopic drive rod 3 retracts, driving the semicircular arc-shaped member 22 to insert into the food and extract the sample. When the primary pendulum 20 swings upward, the secondary pendulum 21 rotates sideways to remove the sample. The two semicircular arc-shaped members 22 form a cylindrical shape, which, when inserted into the food, can cut and remove the sample.

[0034] The tilting unit 23 rotates the sampling gear 19 during its vertical movement, ensuring that the primary rocker arm rotates within a 180° range and then engages the stop block 30. When the secondary rocker arm 21 is at the bottom, the locking rod 26 engages the lower blind groove 24, limiting relative rotation and ensuring that the semicircular member 22 is engaged. When the secondary rocker arm 21 reaches the top, the locking rod 26 enters the upper blind groove 25, allowing the secondary rocker arm 21 to rotate sideways for unloading. A spring 28 provides a reset force, ensuring that all components return to their initial state after operation.
