[0026] Please see Figures 1 to 5 This invention relates to a detection device for detecting mold in food, comprising a detection box 10 with a sampling opening on one side, a detection component 20 movably installed inside the detection box 10, and a sampling component 30 movably installed inside the detection box 10. The sampling component 30 includes a sampling conveyor 31 movably installed inside the detection box 10, a sampling component 32 installed on the sampling conveyor 31, a closed movable component 33 movably installed inside the detection box 10 and connected to the sampling conveyor 31, and a partition 34 installed on the closed movable component 33. When the sampling component 32 enters the detection box 10 through the sampling opening, the partition 34 covers the sampling opening; when the sampling component 32 extends from inside the detection box 10 toward the sampling opening, the partition 34 opens from the sampling opening.
[0027] The working principle of the detection device for detecting mold in food of this utility model is as follows: In use, the operator puts the food sample to be tested into the sampling member 32 through the sampling opening; the sampling member 32 is installed on the sampling conveyor 31 and can move along the track or path inside the detection box 10 to realize the sample transport; during this process, there is a transmission connection between the sampling conveyor 31 and the closed movable member 33, and the closed movable member 33 will also move accordingly as the sampling member 32 moves; when the sampling member 32 enters the detection box 10 through the sampling opening, the partition 34 installed on the closed movable member 33 will automatically cover the sampling opening to prevent microorganisms in the external environment from contaminating the sample, thereby affecting the accuracy of the test results; conversely, when the sampling member 32 moves outward from the detection box 10 to prepare to take a new sample or discharge the tested sample, the partition 34 will open from the sampling opening; after entering the detection box 10, the sample will be transported to the position of the detection component 20, and then the detection component 20 will be used to detect mold in the sample.
[0028] Compared to existing technologies, the detection device for detecting mold in food of this invention features a partition 34 that automatically covers the sampling opening when the sampling component 32 enters the detection chamber 10 through the sampling opening. This effectively prevents microorganisms and dust from entering, ensuring sample purity and improving the accuracy of test results. The device achieves automatic sample transport through the transmission connection between the sampling conveyor 31 and the enclosed movable component 33 installed inside the detection chamber 10. Frequent manual intervention is unnecessary during operation, improving work efficiency and reducing errors and contamination risks caused by human operation. Users simply place the food sample to be tested into the sampling component 32 through the sampling opening; subsequent sample transport and testing are completed automatically. This structure allows even non-professionals to operate the device easily, enhancing its user-friendliness.
[0029] Please refer to Figure 2 and Figure 3The sampling conveyor 31 includes a conveyor motor 310 installed in the detection box 10, a conveyor driven part 311 installed in the detection box 10, and a conveyor belt 312 with one end installed on the conveyor motor 310 and the other end installed on the conveyor driven part 311; the sampling part 32 is installed on the conveyor belt 312; and the enclosed movable part 33 is connected to the conveyor motor 310 in a transmission connection. The conveyor motor 310 provides precise drive, ensuring controllable movement position and speed of the sample 32 within the detection chamber 10; this facilitates automated operation, reduces human error, and improves the accuracy and consistency of testing. The conveyor belt 312 has excellent transmission performance, smoothly conveying the sample 32 from the sampling opening to the position of the detection assembly 20; belt drive also reduces mechanical wear and extends the service life of the equipment. The combination of the conveyor motor 310, the driven part 311, and the conveyor belt 312 constitutes a simple conveying system that is easy to install and maintain; this modular structure makes troubleshooting and component replacement more convenient. The enclosed movable part 33 is connected to the conveyor motor 310, meaning that when the sample 32 moves on the conveyor belt 312, the enclosed movable part 33 will also move synchronously, ensuring that the opening and closing of the partition 34 is synchronized with the entry and exit of the sample 32; this effectively prevents microorganisms and dust from the external environment from entering the detection chamber 10, ensuring the purity of the sample.
[0030] The enclosed moving part 33 includes an enclosed driven part 330 mounted on the detection box 10, and an enclosed conveyor belt 331 with one end mounted on the conveyor motor 310 and the other end mounted on the enclosed driven part 330; a partition 34 is mounted on the enclosed conveyor belt 331. The sampling conveyor 31 and the enclosed moving part 33 are driven simultaneously by the conveyor motor 310 to ensure that the movements of the sampling component 32 and the partition 34 are synchronized. This allows for precise control of the opening and closing time of the partition 34, minimizing the chance of external microorganisms and dust entering the testing chamber 10. The enclosed conveyor belt 331 has excellent transmission performance, enabling smooth and reliable power transmission, ensuring the smooth and accurate movement of the partition 34. This not only improves the reliability of the equipment but also reduces mechanical wear and noise, extending the service life of the equipment. The combined structure of the enclosed driven part 330 and the enclosed conveyor belt 331 makes the structure of the enclosed moving part 33 more compact and modular, facilitating installation and maintenance, and making the overall layout of the equipment more reasonable and space-saving. The entire movement of the enclosed moving part 33 is completed automatically, reducing operator intervention. This not only improves work efficiency but also reduces the impact of human factors on the test results.
[0031] The detection assembly 20 includes a movable detection component 21 movably mounted on the detection box 10, a fixing component 22 mounted on the movable detection component 21, and a detection component 23 mounted on the fixing component 22. The movable detection component 21, movably mounted on the detection box 10, can be flexibly adjusted in position according to the sample location and requirements, enabling the detection assembly 20 to adapt to samples of different shapes and sizes, thus improving the equipment's versatility and adaptability. The fixing component 22, mounted on the movable detection component 21, ensures the fixed position of the detection component 23, avoiding detection errors caused by vibration or movement during the detection process, thereby improving the accuracy and reliability of the detection. The combined structure of the movable detection component 21, the fixing component 22, and the detection component 23 makes the detection assembly 20 modular, facilitating installation, maintenance, and replacement. If any part malfunctions, it can be quickly replaced, reducing equipment downtime and improving equipment availability.
[0032] Please refer to Figure 4 and Figure 5 The fixing component 22 includes a fixing platform 220 mounted on the moving detection component 21, a fixing cavity 221 disposed on the fixing platform 220 for inserting and fixing the detection component 23, and a locking part 222 installed in the fixing cavity 221 for locking the detection component 23. The fixing cavity 221 provides a precise installation position, ensuring that the detection component 23 can be accurately inserted and fixed. This reduces detection errors caused by positional deviations and improves the accuracy and consistency of detection results. The locking part 222 can firmly fix the detection component 23, preventing it from shifting position due to vibration or movement during the detection process; it ensures the stability of the detection process and further improves the reliability of the detection results. The structure of the fixing cavity 221 and the locking part 222 makes the installation and removal of the detection component 23 simple and quick. If different detection components 23 need to be replaced, the operator can complete the task quickly, improving the flexibility and adaptability of the equipment. The combined structure of the fixing platform 220, the fixing cavity 221, and the locking part 222 makes the fixing component 22 modular, which is convenient for maintenance and replacement. If a part malfunctions, it can be replaced quickly, reducing equipment downtime.
[0033] The fixing cavity 221 includes a vertical channel 221A through which the fixing member 22 passes for the insertion of the detection member 23, and horizontal channels 221B disposed opposite each other on both sides of the vertical channel 221A; the vertical channel 221A and the horizontal channel 221B are connected; the locking part 222 includes a spring 222A installed in the horizontal channel 221B, a ball 222B installed on the spring 222A, and a limiting boss 222C installed on the connection end of the horizontal channel 221B and the vertical channel 221A for limiting the ball 222B; the detection member 23 is provided with a groove that mates with the ball 222B. The vertical channel 221A provides a precise insertion path to ensure that the detection member 23 can be accurately inserted into the fixing cavity 221. The horizontal channel 221B is connected to the vertical channel 221A, which allows the locking part 222 to be triggered when the detection element 23 is inserted, ensuring that it is fixed in the correct position; the structure of the spring 222A and the ball 222B allows the detection element 23 to be firmly locked after insertion; when the groove on the detection element 23 is aligned with the ball 222B, the ball 222B is embedded in the groove under the action of the spring 222A, preventing the detection element 23 from loosening or falling off. This structure ensures the stability of the test piece 23 during the testing process and improves the reliability of the test results. After the test piece 23 is inserted into the vertical channel 221A, the ball bearing 222B will automatically lock, making the operation simple and quick. When disassembly is required, simply pull the test piece 23 outwards gently, and the ball bearing 222B will automatically retract, easily completing the disassembly. This makes the replacement of the test piece 23 more convenient and improves the flexibility and adaptability of the equipment. The structure of the vertical channel 221A and the horizontal channel 221B can accommodate test pieces 23 of different sizes and shapes. As long as the test piece 23 has a groove that matches the ball bearing 222B, it can be firmly fixed, enabling the equipment to flexibly meet different testing needs.
[0034] The detection component 23 includes a detection probe 230 for detection and a positioning rod 231 mounted on the detection probe 230; a groove is provided on the positioning rod 231. The structure of the positioning rod 231 ensures the precise alignment of the detection probe 230 within the fixed cavity 221, reducing detection errors caused by positional deviations; this allows the detection probe 230 to accurately contact the sample, improving the accuracy and consistency of the detection results; the groove on the positioning rod 231 cooperates with the ball bearing 222B of the locking part 222 to ensure that the detection component 23 is firmly fixed within the fixed cavity 221; this structure prevents the detection probe 230 from loosening or falling off during the detection process, improving the reliability of the detection; the structure of the detection probe 230 and the positioning rod 231 makes the installation and disassembly of the detection component 23 simple and quick; the operator only needs to insert the detection component 23 into the vertical channel 221A, and the ball bearing 222B will automatically embed into the groove for fixation; when disassembly is required, gently pull the detection component 23 outwards, and the ball bearing 222B will automatically retract, easily completing the disassembly; this improves the flexibility and adaptability of the equipment.
[0035] Please refer to Figure 3 and Figure 4 The detection movable component 21 includes an X-axis slide rail 210 mounted on the side wall of the detection box 10, an X-axis slider 211 slidably mounted on the X-axis slide rail 210, an X-axis cylinder 212 mounted on the side wall of the detection box 10 for driving the X-axis slider 211, a Y-axis slide groove 213 mounted on the X-axis slider 211, a Y-axis slider 214 slidably mounted on the Y-axis slide groove 213, a Y-axis cylinder 215 mounted on the Y-axis slider 214 for driving the Y-axis slider 214, and a Z-axis cylinder 216 mounted on the Y-axis slider 214; the fixing component 22 is mounted on the Z-axis cylinder 216. The combination of X-axis, Y-axis, and Z-axis motion allows the moving part 21 to move freely in three-dimensional space, achieving precise three-dimensional positioning of the sample. This structure can adapt to samples with various complex shapes and positions, improving the versatility and flexibility of the equipment. The X-axis cylinder 212, Y-axis cylinder 215, and Z-axis cylinder 216 typically employ high-precision drive devices, enabling micron-level precise control. This high-precision control ensures the accuracy and stability of the moving part 21 during movement, improving the reliability of the test results. The X-axis, Y-axis, and Z-axis cylinders can be integrated into the control system for automated operation. Operators can set the sampling path and position through control software to automatically complete sample sampling and testing, reducing human intervention and improving work efficiency. The moving part 21 can move flexibly along the X, Y, and Z axes, allowing for precise adjustments based on the specific position and shape of the sample.

The sampling slider 320 is slidably mounted on the sampling conveyor 31, enabling precise movement along the conveyor to ensure accurate positioning of the sampling tube during the sampling process. This structure reduces sampling errors caused by positional deviations, improving the accuracy of sampling and testing. The sliding structure of the sampling slider 320 allows the sampling stage 321 to perform sampling at different positions, adapting to samples of different sizes and locations. This flexibility improves the adaptability and versatility of the equipment. The sampling mounting cavity 322 provides a stable placement position for the sampling tube, ensuring that the sampling tube will not loosen or tilt during the testing process. This structure ensures the stability and reliability of the test results. If multiple sampling mounting cavities 322 are provided on the sampling stage 321, multiple sampling tubes can be placed simultaneously, enabling simultaneous testing of multiple samples. This improves testing efficiency and reduces operation time.
[0037] A countersunk hole is provided on the side of the sampling installation cavity 322 near the sampling element 32. The countersunk hole structure provides additional clearance space for the sampling element 32, reducing interference between the sampling element 32 and the sampling installation cavity 322 during insertion and removal. This allows the sampling element 32 to enter and exit the sampling installation cavity 322 more smoothly, avoiding jamming or damage caused by interference. The countersunk hole structure can guide the sampling element 32 to be more accurately aligned when entering the sampling installation cavity 322. This helps ensure that the sampling element 32 does not deviate during insertion, improving the fitting accuracy between the sampling element 32 and the sampling installation cavity 322, thereby improving the accuracy and reliability of sampling. The countersunk hole structure reduces friction between the sampling element 32 and the sampling installation cavity 322, extending the service life of both the sampling element 32 and the installation cavity. This structure helps reduce equipment maintenance costs and failure rates.
