Description

Technical Field

[0001] This invention relates to the field of food testing equipment technology, and in particular to a food testing device based on intelligent sensors. Background Technology

[0002] As a crucial component of modern production lines, food metal detection equipment utilizes mature and reliable technology based on electromagnetic induction to detect metallic foreign objects, effectively protecting products from metal contamination. However, this technology has an inherent limitation: it can only identify metals and is completely ineffective against non-metallic foreign objects such as plastics, stones, and glass. This limitation results in significant vulnerabilities when detecting complex ingredients like tripe. The tightly layered structure of tripe in such ingredients creates numerous deep gaps, providing natural hiding places for non-metallic foreign objects and making it difficult for any single technology to achieve comprehensive coverage. Currently, to compensate for the functional deficiencies of metal detection equipment, manufacturers have to set up inefficient manual inspection stations. This method is not only labor-intensive but also susceptible to human eye fatigue and negligence, leading to highly unstable detection results and a high rate of missed detections, posing a significant food safety risk. Therefore, this paper proposes a food detection device based on intelligent sensors to address these issues. Summary of the Invention

[0008] As a further improvement of the present invention, the tapping device includes a limiting block. A T-shaped limiting block is slidably positioned on the outer side of the rotating block of the adsorption device. An arc-shaped push block is fixedly connected to one end of the outer side of the limiting block, and the push blocks are arranged in a ring. A first spring is fixedly connected to the top of the limiting block, and the other end of the first spring is fixedly connected to the rotating block of the adsorption device. A connecting shaft is fixedly connected to the bottom of the limiting block, and the connecting shaft passes through the rotating block of the adsorption device.

A fixed rod is fixedly connected to the rear end of the toggle rod and fixedly connected to the support plate. A toggle motor is fixedly connected to the bottom of the rear end of the fixed rod, and the toggle rod is fixedly connected to the main shaft of the toggle motor.

[0009] As a further improvement of the present invention, the driving device includes a drive motor. The drive motor is fixedly connected to the rear end of the left side of the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: By using an adsorption device to horizontally lift the tripe with the louvers facing downwards, a stable benchmark is provided for subsequent operations. Then, an adjustment device, in conjunction with a detection device, gradually opens up the louver folds, thoroughly exposing the root area that is difficult to detect using traditional methods. When a non-metallic foreign object is detected, a tapping device precisely taps it from the top, shaking the foreign object into a dedicated collection device, forming a complete closed loop of "positioning adsorption - opening detection - foreign object removal". By adding a dedicated pre-treatment step before the traditional metal detection process, the problem of detecting non-metallic foreign objects is fundamentally solved. Compared with traditional manual sorting, this device not only frees operators from heavy and error-prone labor, significantly reducing labor intensity, but more importantly, through stable mechanized operation, it significantly improves the accuracy and consistency of foreign object detection, effectively eliminating missed detections caused by human fatigue or negligence, providing a more reliable guarantee for food safety, and has significant practical value and application prospects.

[0025] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. To better illustrate the specific embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size.

It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. All other specific embodiments obtained by those skilled in the art based on the specific embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example. For example... Figure 1-10As shown, a food detection device based on intelligent sensors includes a food metal detector 1. A support plate 2 is fixedly connected to one side of the top of the food metal detector 1 via a connecting rod. An adsorption device 3 for sucking up tripe is provided on the left inner side of the support plate 2. An adjustment device 4 for adjusting the position of the tripe is provided on the top outer side of the adsorption device 3. A beating device 5 for shaking off non-metallic foreign objects in the tripe is provided on the bottom outer side of the adsorption device 3. A driving device 6 is provided on the right inner side of the support plate 2. A separating detection device 7 for separating the tripe is provided on one side of the driving device 6. A collection device 8 for collecting the shaken-off foreign objects is provided on the other side of the driving device 6. A controller 9 is fixedly connected to the left side of the support plate 2. An inclined ultrasonic sensor 10 is fixedly connected to the left side of the bottom of the support plate 2 via a connecting rod.

[0027] Furthermore, such as Figure 1-6 As shown, to address the issue of difficulty in lifting beef tripe to the detection position and allowing it to hang naturally for subsequent detection, the adsorption device 3 includes a support 301. The support 301 is fixedly connected to the top left of the support plate 2. A large electric push rod 302 is fixedly connected to the top inner side of the support 301. A fixing sleeve 303, penetrating the support plate 2, is fixedly connected to the bottom of the large electric push rod 302, and the fixing sleeve 303 can slide up and down with the support plate 2. A rotating block 304 is rotatably connected to the bottom inner side of the fixing sleeve 303. A small electric push rod 305, penetrating the rotating block 304, is provided on the top inner side of the rotating block 304. A fixing plate 308 is rotatably connected to the bottom of the small electric push rod 305, and the fixing plate 308 can slide up and down within the rotating block 304. A ring-shaped piston rod 309 is fixedly connected to the bottom of the fixing plate 308, and a piston block 310 is fixedly connected to the bottom of the piston rod 309. The stopper block 310 can slide up and down within the rotating block 304. The bottom of the piston block 310 is provided with a limiting sleeve 311 fixedly connected to the rotating block 304. The bottom of the limiting sleeve 311 is connected to a suction cup 312. Under the control of the controller 9, the large electric push rod 302 extends a specified distance. The fixed sleeve 303, the rotating block 304 and the limiting sleeve 311 control the suction cup 312 to make close contact with the top of the louvered beef tripe facing downward. Then, the small electric push rod 305 is controlled to retract. The fixed plate 308 and the piston rod 309 control the piston block 310 to move upward. When a negative pressure is generated in the sealed cavity formed by the suction cup 312, the limiting sleeve 311, the piston block 310 and the beef tripe, the suction cup 312 tightly sucks the beef tripe. After the large electric push rod 302 is reset, the suction cup 312 simultaneously drives the beef tripe to move upward, which facilitates the suction of the beef tripe to the detection position so that the beef tripe hangs down naturally to prepare for subsequent detection operations.

[0028] Furthermore, such as Figure 2 and Figure 4As shown, to solve the problem of not being able to automatically determine whether the tripe is tightly adsorbed by the suction cup 312, a pressure plate 306 that contacts the fixed sleeve 303 is fixedly connected to the top of the small electric push rod 305. A pressure sensor 307 that contacts the fixed sleeve 303 is fixedly connected to the bottom of the pressure plate 306. During the process of controlling the small electric push rod 305 to retract and generate negative pressure in the sealed cavity formed by the suction cup 312, the limiting sleeve 311, the piston block 310 and the tripe, the small electric push rod 305 simultaneously pulls the pressure plate 306 to press the pressure sensor 307. When the pressure value sensed by the pressure sensor 307 reaches the preset range, the small electric push rod 305 is further controlled to stop retracting, which facilitates the automatic determination of whether the tripe is tightly adsorbed by the suction cup 312.

[0029] Furthermore, such as Figure 2 As shown, to address the issue of inconvenience in switching the orientation of the tripe after each test and performing subsequent inspections by peeling back the folds, the adjusting device 4 includes an adjusting motor 401. The adjusting motor 401 is fixedly connected to the right side of the top of the fixed sleeve 303 of the adsorption device 3. A gear 402 is fixedly connected to the end of the main shaft of the adjusting motor 401. A gear ring 403 is meshed with the outer side of the gear 402, and the gear ring 403 is fixedly connected to the rotating block 304 of the adsorption device 3. During subsequent inspections of the tripe, after each test, the adjusting motor 401, under the control of the controller 9, drives the gear 402 to mesh with the gear ring 403 and rotate. This further drives the tripe at the bottom of the suction cup 312 to rotate through the rotating sleeve 304 and the limiting sleeve 311, facilitating the switching of the tripe's orientation and thus enabling subsequent inspections by peeling back the folds.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, to address the problem of difficulty in removing non-metallic foreign objects detected between the slats of beef tripe, the tapping device 5 includes a limiting block 501. A T-shaped limiting block 501 is slidably positioned on the outer side of the rotating block 304 of the adsorption device 3. An arc-shaped push block 502 is fixedly connected to one end of the outer side of the limiting block 501, and the push blocks 502 are arranged in a ring. A first spring 503 is fixedly connected to the top of the limiting block 501, and the other end of the first spring 503 is connected to the adsorption device. The rotating block 304 of the attached device 3 is fixedly connected. The bottom end of the limiting block 501 is fixedly connected to the connecting shaft 504, and the connecting shaft 504 passes through the rotating block 304 of the adsorption device 3. The connecting shaft 504 is slidably connected to the rotating block 304 of the adsorption device 3. The bottom end of the connecting shaft 504 is fixedly connected to a fan-shaped beater 505, and the beaters 505 are arranged in a ring. The beaters 505 are located outside the suction cup 312 of the adsorption device 3. The bottom of the push block 502 on the right side contacts a pusher. The lever 506 has a fixed rod 507 at its rear end, which is fixedly connected to the support plate 2. A lever motor 508 is fixedly connected to the bottom rear end of the fixed rod 507, and the lever 506 is fixedly connected to the main shaft of the lever motor 508. When a non-metallic foreign object is detected between the louvers of the louvers, the lever 506 is rotated by the lever motor 508 under the control of the controller 9. The lever 506 then pushes the push block 502 at the corresponding position upwards. 02 will drive the corresponding limit block 501 upward, the corresponding limit block 501 will compress the corresponding first spring 503, and at the same time, it will drive the corresponding clapper 505 upward through the corresponding connecting shaft 504. When the toggle lever 506 disengages from the corresponding push block 502, the clapper 505 will quickly reset under the elastic force of the first spring 503, and further clapper from the top to the beef tripe, causing it to vibrate, which facilitates the removal of non-metallic foreign objects detected between the louvers of the beef tripe.

[0031] Furthermore, such as Figure 1 , Figure 2 and Figure 8As shown, to address the issue of inconvenience in simultaneously controlling the opening detection device 7 and the drive device 6 to their designated positions using differential speed during the opening detection of beef tripe, the drive device 6 includes a drive motor 601. The drive motor 601 is fixedly connected to the rear left side of the support plate 2. A first threaded shaft 602, rotatably connected to the support plate 2, is fixedly connected to the end of the main shaft of the drive motor 601. A small sprocket 603 is fixedly connected to the right end of the first threaded shaft 602. A chain 604 is meshed with the outer side of the small sprocket 603, and a chain 604 is meshed with the front end of the inner side of the chain 604. The large sprocket 605 has a second threaded shaft 606 fixedly connected to its left end and rotatably connected to the support plate 2. When the louvers of the beef tripe are being opened for detection, the first threaded shaft 602 is rotated by the drive motor 601 under the control of the controller 9 to control the collecting device 8 to move to the designated position. At the same time, the second threaded shaft 606 is slowly rotated under the meshing of the small sprocket 603 and the large sprocket 605 with the chain 604, further controlling the opening detection device 7 to slowly move to the designated position. This facilitates the use of differential speed to simultaneously control the opening detection device 7 and the drive device 6 to move to the designated positions.

[0032] Furthermore, such as Figure 1 , Figure 2 and Figure 9As shown, to address the problem that it is inconvenient to open the louvers of the bean curd flap to detect non-metallic foreign objects in the folds when the detection device 7 is brought closer to the flap, the detection device 7 includes a positioning block 701. The positioning block 701 is spirally connected to the outer side of the second threaded shaft 606 of the drive device 6, and the positioning block 701 is slidably connected to the support plate 2. A second spring 702 is fixedly connected to both the front and rear ends of the inner side of the positioning block 701, and the other end of the second spring 702 is fixedly connected to a limiter that slides on the positioning block. The limiting rod 703 inside 701 has a rotating rod 704 rotatably connected to its left top end via a rotating shaft. The other end of the rotating rod 704 is rotatably connected to a connecting block 705 via a rotating shaft. The left side of the connecting block 705 has a fixing block 709 fixedly connected to the support plate 2. The bottom left end of the limiting rod 703 is fixedly connected to a disengaging rod 706. The bottom left side of the positioning block 701 is fixedly connected to a position recognition camera 707 and a foreign object recognition camera 708, which are arranged vertically. The control disengagement detection device... 7. When moving closer to the tripod liner to further open and detect the folds of the tripod liner, after the position of the tripod liner is adjusted by the adjusting device 4, the position recognition camera 707 first identifies whether the left end of the dispensing lever 706 is directly aligned with the fold gap of the tripod liner. After the dispensing lever 706 is aligned with the fold gap of the tripod liner, the drive device 6 is activated to control the dispensing lever 706 to insert into the fold gap of the tripod liner. At this time, the dispensing lever 706 will first insert into the fold gap of the tripod liner. When the connecting block 705 contacts the fixing block 709, as the dispensing lever 706 continues to... Upon further insertion, the connecting block 705 will push the limiting rod 703 to compress the second spring 702 via the rotating rod 704. At this time, the two limiting rods 703 will simultaneously drive the corresponding dispensing rods 706 to move away from each other, thereby controlling the dispensing rod 706 to insert into the louver gap of the louver while simultaneously opening the louver. When the dispensing rod 706 is inserted to the designated position, the foreign object recognition camera 708 will take a picture of the opened part of the louver for recognition, which facilitates the detection of non-metallic foreign objects in the folds and gaps of the opened louver.

[0033] Furthermore, such as Figure 1 , Figure 2 and Figure 10 As shown, in order to solve the problem of inconvenience in collecting non-metallic foreign objects that have been knocked off, the collection device 8 includes a support rod 801. The support rod 801 is spirally connected to the outside of the first threaded shaft 602 of the drive device 6, and the support rod 801 is slidably connected to the support plate 2. The bottom of the outside of the support rod 801 is in contact with the collection box 802. The collection box 802 of the collection device 8 moves to the bottom of the part of the tripe that has been opened under the drive of the drive device 6. When the knocking device 5 knocks off the non-metallic foreign objects in the gap of the tripe, it is convenient to collect the knocked-off non-metallic foreign objects.

[0034] The principle of non-metallic removal before metal foreign object detection in beef tripe: The beef tripe is placed on the conveyor of the food metal detector 1 with the tripe facing downwards. The device is then started via controller 9, initiating the food metal detector 1 and conveying the beef tripe to the right. When the ultrasonic sensor 10 detects that the beef tripe has moved to the designated position, i.e., the bottom of the adsorption device 3, the conveyor of the food metal detector 1 stops, the signal from the ultrasonic sensor 10 is blocked, and then the adsorption device 3 adsorbs the beef tripe, simultaneously moving it upwards to the detection position, allowing the tripe to naturally adhere to the adsorption device 3. The device droops down, and then the position recognition camera 707 of the detection device 7 identifies whether the dispensing lever 706 is aligned with the louver gap of the tripod. If it is not aligned, the adjustment device 4, under the control of the controller 9, controls the tripod to rotate horizontally to adjust its position. After adjustment, the drive device 6, under the control of the controller 9, controls the collection device 8 and the dispensing detection device 7 to move to the designated position. At this time, the collection box 802 of the collection device 8 moves to the bottom of the part of the tripod that needs to be dispensed, and the dispensing detection device 7 inserts into the louver gap of the tripod during the movement. Simultaneously, the louvers are opened to both sides, revealing gaps in the louver openings. The foreign object detection camera 708 then identifies any foreign objects in these gaps. When a non-metallic foreign object is detected, the tapping device 5 taps the louvers from the top, further dislodging the non-metallic foreign object into the collection box 802 of the collection device 8. When no non-metallic foreign object is detected, the driving device 6 controls the opening of the detection device 7 and the resetting of the collection device 8. Then, the adjusting device 4 continues to adjust the position of the louvers until the dispersing lever 706 is aligned with the adjacent louver gap, and the process is repeated. The above operation continues until all the louver gaps are opened for inspection. After the inspection is completed, the adsorption device 3 puts the tripe back onto the conveyor of the food metal detector 1. Then, the tripe that has passed through the non-metallic foreign object detection section of the metal detector 1 is controlled to pass through for metal foreign object detection. At the same time, the signal shield of the ultrasonic sensor 10 is released to prepare for the inspection of the next tripe. In this solution, the controller 9 integrates a PLC control system, which coordinates the orderly operation of the electrical appliances in the control device through a preset program to ensure the stability and reliability of the coordinated operation of each electrical appliance.
