Description

Technical Field

[0001] This invention relates to the field of food testing technology, and more specifically to a screening and conveying device for food testing samples. Background Technology

[0002] In today's world, where food quality and safety are receiving increasing attention, food testing, as a crucial link in protecting consumer health and maintaining market order, directly impacts the sustainable development of the food industry through its efficiency and accuracy. In traditional food testing processes, sample processing and screening are paramount, affecting not only the accuracy of test results but also the efficiency of the testing work. However, existing food testing sample screening and conveying devices have numerous design limitations, particularly in achieving comprehensive testing of food samples, where significant technical challenges remain.

[0003] Most food testing sample conveying devices on the market currently use a single conveyor belt or slide rail structure to transport the sample to be tested from one end to the other for testing at a fixed angle. Although this design is simple and efficient, it cannot meet the needs of multi-angle and all-round testing of food samples. Single-view testing often fails to fully capture the appearance defects, which can easily lead to omissions and affect the accuracy and reliability of food safety assessment. In addition, although manual flipping testing can solve this problem to some extent, it is labor-intensive, inefficient, and easily affected by human factors, making it difficult to guarantee the consistency and objectivity of the test.

[0004] Therefore, the present invention provides a screening and conveying device for food testing samples to solve the above-mentioned problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a screening and conveying device for food testing samples, so as to solve the problem of being able to flip food samples for testing, realize all-round testing, and avoid the phenomenon of missed testing.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A food sample screening and conveying device includes a base, a detection component, a conveying component, and a flipping clamping component. The detection component includes a detection frame and a detection plate. The detection frame is fixedly installed at the top of the center of the base, and the detection plate is slidably connected to the bottom of the detection frame. The conveying component includes a conveyor belt and a conveying gear. The conveyor belt is rotatably connected inside the base and is driven by the conveying gear to the detection plate. The flipping clamping component includes a fixed box, a rotating ring, and a fixed ring. The fixed box is fixedly installed on the outer wall of the conveyor belt, and the rotating ring is rotatably connected to the outer wall of the fixed box. The rotating ring has a fixed ring slidably mounted at one end, which matches the outer wall of the food sample. In use, the device detects the upper part of the food sample via a detection plate, while the fixed ring automatically clamps the outer wall of the sample, integrating detection and clamping into a single, linked function. To prevent missed detections and ensure the bottom and sides of the food sample are inspected, the rotating ring rotates as the detection plate descends, flipping the food sample and allowing for comprehensive, all-around detection.

[0007] Preferably, there are multiple fixed boxes, with two fixed boxes forming a group, and the fixed boxes in a group are arranged opposite to each other; the flipping shaft is rotatably connected to the inner side wall of the fixed box, and the rotating ring is fixedly installed on the outer wall of the flipping shaft.

[0008] Preferably, an adjusting shaft is threadedly connected to the outer wall of the rotating ring, and a connecting plate is fixedly installed on the outer wall of the adjusting shaft; a threaded rod is threadedly connected to the inner wall of the fixed ring, the threaded rod is slidably connected to the adjusting shaft, and a connecting groove is formed on the inner wall of the threaded rod, the connecting groove matching the connecting plate.

[0009] Preferably, a stop ring is slidably connected to the inner wall of the fixing ring, a stop spring is fixedly installed at one end of the stop ring, and the other end of the stop spring is fixedly connected to the inner wall of the fixing ring; an outer ring is fixedly installed on the outer wall of the fixing ring, and a bearing ring is provided on the outer wall of the outer ring; when in use, the device initially clamps the outer wall of the food sample by the stop ring on the inner wall of the fixing ring to achieve the function of fixing. At the same time, in order to be suitable for the detection and clamping of food samples of various sizes, the device rotates the adjusting shaft, which drives the threaded rod to rotate, thereby adjusting the position of the fixing ring and realizing the initial position of the fixing ring.

[0010] Preferably, a flipping gear is fixedly installed on the outer wall of the flipping shaft, a spiral spring is fixedly installed on the outer wall of one end of the flipping shaft, and the other end of the spiral spring is fixedly connected to the inner side wall of the fixed box.

[0011] Preferably, the detection plate is fixedly connected to the output end of the detection cylinder, and the detection cylinder is fixedly installed on the top of the detection frame; a detector is installed in the middle of the bottom of the detection plate, and a flipping toothed plate is fixedly installed on one side of the bottom of the detection plate, the flipping toothed plate matching the flipping gear; a lower pressure plate is fixedly installed on one side of the flipping toothed plate, the lower pressure plate matching the outer ring, and the outer wall of the top of the flipping toothed plate is set as a smooth plate; a transmission toothed plate is fixedly installed on one side of the detection plate, and the transmission toothed plate is drivenly connected to the conveyor belt; when the device is in use, by activating the detection cylinder, the detection cylinder drives the detection plate to move downward, so that the detector detects the outer surface of the food sample, and at the same time, the flipping toothed plate will mesh with the flipping gear. The device lowers the flipping plate, causing the flipping gear to rotate. The worm spring is compressed. When the flipping plate descends to the bottom, the plate's surface aligns with the flipping gear, disengaging the gear and releasing the worm spring's limit, reversing to its original position. At this point, the detector is positioned closer to the food sample, facilitating detection. The flipping shaft flips the clamped food sample, and the detector performs the flipping detection. By lowering the detection plate, the device reduces the distance between the detector and the food sample, allowing for more intuitive and clear detection, ensuring accurate data. It also enables automatic flipping to prevent missed detections. The device's detection and flipping functions are linked, automatically flipping only during detection to prevent unnecessary idling of the food sample.

[0012] Preferably, a sliding frame is slidably connected to the inner wall of the fixed box. A clamping shaft is fixedly installed at one end of the sliding frame, and the clamping shaft abuts against the outer wall of the bearing ring. A sliding plate is fixedly installed at the other end of the sliding frame, and a sliding groove is formed on the inner wall of the sliding plate. A sliding inclined block is slidably connected to the inner wall of the fixed box. The width of the sliding inclined block decreases from top to bottom. The inclined surface of the sliding inclined block abuts against the sliding groove. A supporting frame is fixedly installed at the top of the sliding inclined block, and the supporting frame matches the lower pressure plate. A return spring is fixedly installed at the bottom of the sliding inclined block, and the other end of the return spring is fixedly attached to the inner bottom wall of the fixed box. Fixed connection; In use, the food sample is placed in the gap between two fixed boxes. At this time, the top ring provides initial clamping function to the outer wall of the food sample. At the same time, when the detection plate moves downward, the lower pressure plate will abut against the top of the top frame, which in turn causes the sliding block to abut against the sliding plate, driving the sliding plate to move outward. At this time, the clamping shaft moves outward and abuts against the bearing ring on the outer wall of the outer ring, causing the clamping shaft to drive the fixed ring to move outward, so that the fixed ring clamps and fixes the food sample. This creates a linkage between detection and fixation, preventing the food sample from being unable to be flipped over during detection.

[0013] Preferably, external teeth are fixedly installed on the outer wall of the transmission gear plate, and there are multiple external teeth. A sliding plate is slidably connected inside the transmission gear plate. An internal tooth is fixedly installed on the outer wall of one end of the sliding plate, and the internal tooth is located at the interval between two external teeth. A sliding rod is fixedly installed on the outer wall of the other end of the sliding plate.

[0014] Preferably, the conveyor belt is rotatably connected to a conveyor roller, the outer wall of the conveyor roller is fixedly mounted with a conveyor shaft, the conveyor gear is unidirectionally driven and connected to the outer wall of the conveyor shaft, and the conveyor gear is meshed with the transmission gear plate.

[0015] Preferably, the conveying shaft has a conveying groove inside, and a conveying block is slidably connected inside the conveying groove. One end of the conveying block is triangular in shape, and a conveying spring is fixedly installed at one end of the conveying block inside the conveying groove. The other end of the conveying spring is fixedly connected to the inner wall of the conveying groove. The inner wall of the conveying gear has a slot that matches the conveying block. When the detection plate of this device performs a downward detection, it will simultaneously drive the transmission gear plate to move downward. When the transmission gear plate moves downward, the inclined surface of the conveying block on the inner wall of the conveying shaft is opposite to the inclined surface of the slot. At this time, the rotation of the conveying gear will not drive the conveying shaft to rotate. When the detection plate finishes detection... When resetting upwards, the straight surface of the conveyor block inside the conveyor shaft is opposite to the straight surface of the slot, causing the conveyor gear to drive the conveyor shaft to rotate, thereby driving the conveyor belt to rotate and realizing the conveying function. Through the setting of the conveyor gear and the transmission gear plate, this device can synchronously drive the conveyor belt to rotate when the detection plate is performing detection, realizing the function of detection and conveying linkage, and avoiding the phenomenon of failure to detect caused by the conveyor belt rotating when descending. In order to be suitable for the detection of various foods, the device can realize the number of meshing teeth on the outer wall of the transmission gear plate through the setting of internal and external teeth, thereby realizing different transmission distances for driving the conveyor belt, which is convenient for the detection and conveying of different foods.

[0016] The beneficial effects of this invention are as follows: 1. When in use, this device detects the upper part of the food sample through the detection plate, while the fixing ring automatically clamps the outer wall of the food sample, integrating detection and clamping into a single, linked function. To avoid missed detections and prevent the bottom and sides of the food sample from being undetectable, the device's rotating ring rotates when the detection plate descends for detection, turning the food sample over so that the detection plate can detect the food sample from all angles without any blind spots.

[0017] 2. When using this device, the outer wall of the food sample is initially clamped by the abutment ring on the inner wall of the fixing ring to achieve the function of fixation. At the same time, in order to be suitable for testing and clamping food samples of various sizes, this device can rotate the adjusting shaft, which drives the threaded rod to rotate, thereby adjusting the position of the fixing ring and adjusting the initial position of the fixing ring. After clamping, this device can flip the food sample for testing by using the flipping shaft.

[0018] 3. By lowering the detection plate, this device can reduce the distance between the detector and the food sample, making the detection more intuitive and clear, ensuring the accuracy of the detection data. At the same time, it can automatically flip the sample to avoid missing any samples. The detection and flipping functions of this device are linked, so that the sample can be automatically flipped only during detection to prevent the food sample from spinning idly.

[0019] 4. When using this device, the food sample is placed in the gap between two fixed boxes. At this time, the top ring provides initial clamping function for the outer wall of the food sample. At the same time, when the detection plate moves downward, the lower pressure plate will abut against the top of the top frame, which in turn causes the sliding block to abut against the sliding plate, driving the sliding plate to move outward. At this time, the clamping shaft moves outward and abuts against the bearing ring on the outer wall of the outer ring, causing the clamping shaft to drive the fixed ring to move outward, so that the fixed ring clamps and fixes the food sample. This creates a linkage between detection and fixation, preventing the food sample from being unable to be flipped over during detection.

[0020] 5. This device, through the arrangement of conveyor gears and transmission gear plates, enables the conveyor belt to rotate synchronously when the detection plate is performing detection, realizing the function of linkage between detection and conveying. It also avoids the phenomenon of failure to detect caused by the conveyor belt rotating during descent. In order to be suitable for the detection of various foods, the device, through the arrangement of internal and external teeth, can realize the number of meshing teeth on the outer wall of the transmission gear plate, thereby enabling the conveyor belt to drive different transmission distances, which is convenient for the detection and conveying of different foods.

Figure 1-3 As shown, it includes a base 1, a detection component, a conveying component, and a flipping clamping component; the detection component includes a detection frame 2 and a detection plate 3, the detection frame 2 is fixedly installed on the top of the middle part of the base 1, and the detection plate 3 is slidably connected to the bottom of the detection frame 2; as shown in the attached figure. Figure 8As shown, the conveying component includes a conveyor belt 4 and a conveying gear 5. The conveyor belt 4 is rotatably connected inside the base 1, and the conveyor belt 4 is driven and connected to the detection plate 3 through the conveying gear 5. The flipping clamping component includes a fixed box 6, a rotating ring 7, and a fixed ring 8. The fixed box 6 is fixedly installed on the outer wall of the conveyor belt 4, and the rotating ring 7 is rotatably connected to the outer wall of the fixed box 6. The fixed ring 8 is slidably set at one end of the rotating ring 7, and the fixed ring 8 matches the outer wall of the food sample. When this device is in use, the upper part of the food sample is detected by the detection plate 3, and the outer wall of the food sample is automatically clamped by the fixed ring 8, so that the detection and clamping are integrated and linked. At the same time, in order to avoid the phenomenon of missed detection and prevent the bottom and sides of the food sample from being undetectable, the rotating ring 7 of this device can rotate when the detection plate 3 is lowered for detection, so as to achieve the flipping of the food sample, allowing the detection plate 3 to detect the food sample from all directions without blind spots.

[0025] As attached Figure 2-3 As shown, there are multiple fixed boxes 6, with two fixed boxes 6 forming a group, and a group of fixed boxes 6 are arranged opposite each other; the flipping shaft 701 is rotatably connected to the inner wall of the fixed box 6, and the rotating ring 7 is fixedly installed on the outer wall of the flipping shaft 701.

[0026] As attached Figure 3-4 As shown, an adjusting shaft 702 is threadedly connected to the outer wall of the rotating ring 7, and a connecting plate 703 is fixedly installed on the outer wall of the adjusting shaft 702; a threaded rod 704 is threadedly connected to the inner wall of the fixed ring 8, and the threaded rod 704 is slidably connected to the adjusting shaft 702. A connecting groove 705 is provided on the inner wall of the threaded rod 704, and the connecting groove 705 matches the connecting plate 703.

[0027] As attached Figure 3 and attached Figure 5 As shown, a top ring 801 is slidably connected to the inner wall of the fixed ring 8. A top spring 802 is fixedly installed at one end of the top ring 801, and the other end of the top spring 802 is fixedly connected to the inner wall of the fixed ring 8. An outer ring 803 is fixedly installed on the outer wall of the fixed ring 8, and a bearing ring 804 is provided on the outer wall of the outer ring 803. When this device is in use, the top ring 801 on the inner wall of the fixed ring 8 initially clamps the outer wall of the food sample to achieve the function of fixing. At the same time, in order to be suitable for the detection and clamping of food samples of various sizes, this device rotates the adjusting shaft 702, which drives the threaded rod 704 to rotate, thereby adjusting the position of the fixed ring 8 and adjusting the initial position of the fixed ring 8. After clamping, this device can flip the food sample for detection by using the flipping shaft 701.

[0028] As attached Figure 2As shown, a flipping gear 706 is fixedly installed on the outer wall of the flipping shaft 701, a worm spring 707 is fixedly installed on the outer wall of one end of the flipping shaft 701, and the other end of the worm spring 707 is fixedly connected to the inner side wall of the fixed box 6.

[0029] As attached Figure 6 As shown, the detection plate 3 is fixedly connected to the output end of the detection cylinder 201, which is fixedly installed on the top of the detection frame 2. A detector 301 is installed in the middle of the bottom of the detection plate 3. A flipping toothed plate 302 is fixedly installed on one side of the bottom of the detection plate 3, and the flipping toothed plate 302 matches the flipping gear 706. A lower pressure plate 303 is fixedly installed on one side of the flipping toothed plate 302, and the lower pressure plate 303 matches the outer ring 803. The outer wall of the top of the flipping toothed plate 302 is a smooth plate. A transmission toothed plate 304 is fixedly installed on one side of the detection plate 3, and the transmission toothed plate 304 is drivenly connected to the conveyor belt 4. When the device is in use, the detection cylinder 201 is activated, causing the detection cylinder 201 to drive the detection plate 3 to move downwards, allowing the detector 301 to detect the outer surface of the food sample. Simultaneously, the flipping toothed plate 302 will mesh with the flipping gear 706, making... The flipping toothed plate 302 drives the flipping gear 706 to rotate, and the worm spring 707 is in a compressed state. When the flipping toothed plate 302 continues to descend to the bottom, the smooth plate of the flipping toothed plate 302 is opposite to the flipping gear 706, the flipping gear 706 disengages, the worm spring 707 loses its limit and reverses to reset. At this time, the detector 301 is positioned at a smaller distance from the food sample, which facilitates detection. The flipping shaft 701 drives the clamped food sample to flip over, and the detector 301 performs flip detection. This device can reduce the distance between the detector 301 and the food sample by lowering the detection plate 3, which facilitates more intuitive and clear detection, ensures the detection data, and realizes automatic flipping to ensure that no detection is missed. The detection and flipping of this device form a linkage function, so that it can automatically flip over only during detection to prevent the food sample from spinning idly.

[0030] As attached Figure 2 and attached Figure 7As shown, a sliding frame 601 is slidably connected to the inner wall of the fixed box 6. A clamping shaft 602 is fixedly installed at one end of the sliding frame 601, and the clamping shaft 602 abuts against the outer wall of the bearing ring 804. A sliding plate 603 is fixedly installed at the other end of the sliding frame 601, and a sliding groove 604 is provided on the inner wall of the sliding plate 603. A sliding inclined block 605 is slidably connected to the inner wall of the fixed box 6. The width of the sliding inclined block 605 decreases from top to bottom. The inclined surface of the sliding inclined block 605 abuts against the sliding groove 604. A supporting frame 606 is fixedly installed at the top of the sliding inclined block 605. The supporting frame 606 matches the lower pressure plate 303. A return spring 607 is fixedly installed at the bottom of the sliding inclined block 605. The other end of the return spring 607 is fixedly connected to the inner bottom wall of the fixed box 6. In use, the food sample is placed between two fixed boxes 6. The abutment ring 801 initially clamps the outer wall of the food sample. Simultaneously, when the detection plate 3 moves downward, the pressure plate 303 abuts against the top of the abutment frame 606, causing the sliding block 605 to abut against the sliding plate 603. This causes the sliding plate 603 to move outward, and the clamping shaft 602 moves outward and abuts against the bearing ring 804 on the outer wall of the outer ring 803. This causes the clamping shaft 602 to move the fixed ring 8 outward, thus clamping and fixing the food sample. This creates a linkage between detection and fixing, preventing the food sample from being unable to be flipped during detection.

[0031] As attached Figure 8 As shown, external teeth 306 are fixedly installed on the outer wall of the transmission gear plate 304. There are multiple external teeth 306. A sliding plate 305 is slidably connected inside the transmission gear plate 304. An internal tooth 307 is fixedly installed on the outer wall of one end of the sliding plate 305.

A conveyor gear 5 is unidirectionally driven and connected to the outer wall of the conveyor shaft 402, and the conveyor gear 5 is meshed with the transmission gear plate 304.

[0033] As attached Figure 10As shown, a conveying groove 404 is provided inside the conveying shaft 402. A conveying block 405 is slidably connected inside the conveying groove 404. One end of the conveying block 405 is triangular in shape. A conveying spring 403 is fixedly installed at one end of the conveying block 405 inside the conveying groove 404. The other end of the conveying spring 403 is fixedly connected to the inner wall of the conveying groove 404. A slot 501 is provided on the inner wall of the conveying gear 5, which matches the conveying block 405. When the detection plate 3 of this device performs a downward detection, it will synchronously drive the transmission gear plate 304 to move downward. When the transmission gear plate 304 moves downward, the inclined surface of the conveying block 405 on the inner wall of the conveying shaft 402 is opposite to the inclined surface of the slot 501. At this time, the rotation of the conveying gear 5 will not drive the conveying shaft 402 to rotate. When the detection plate 3... After the test is completed and the device is reset upwards, the straight surface of the conveyor block 405 inside the conveyor shaft 402 is opposite to the straight surface of the slot 501, causing the conveyor gear 5 to drive the conveyor shaft 402 to rotate, thereby driving the conveyor belt 4 to rotate and realizing the conveying function. Through the arrangement of the conveyor gear 5 and the transmission gear plate 304, this device can synchronously drive the conveyor belt 4 to rotate when the detection plate 3 is performing the test, realizing the function of linkage between detection and conveying, and avoiding the phenomenon of failure to detect caused by the conveyor belt 4 rotating when descending. In order to be suitable for the detection of various foods, the device can realize the number of meshing teeth on the outer wall of the transmission gear plate 304 through the arrangement of the inner teeth 307 and the outer teeth 306, thereby realizing different transmission distances for driving the conveyor belt 4, which is convenient for the detection and conveying of different foods.
