Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing, and in particular to a foreign object identification device for staple food dishes. Background Technology
[0002] Foreign object identification equipment for staple food dishes is mainly used for food safety testing to ensure that staple food products such as bread, pastries, rice and flour products are not contaminated by harmful impurities such as metal, glass, and stones during processing. Common methods for identifying foreign objects in food include photography and X-ray imaging.
[0003] Existing foreign object detection devices cannot quickly distinguish between foreign objects inside and outside the packaging. If there is a foreign object attached to the outside of the packaging bag, the device will directly determine that there is a foreign object in the entire package, which then requires manual re-inspection and judgment. This increases the labor intensity of manual labor and affects the overall food identification efficiency. At the same time, when using photography to identify staple food dishes after packaging, the camera is usually fixed directly above the staple food dishes. If the staple food dishes are stacked high, the sides of the staple food dishes after packaging cannot be directly photographed, which may result in missing some staple food dishes containing foreign objects. In addition, some light may shine on the outside of the food packaging and cause reflection, which often leads to identification errors. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] like Figures 1-9 As shown, a foreign object identification device for staple food dishes includes a conveying mechanism 3, a pushing mechanism 4 in the middle of the conveying mechanism 3, an upper support cover 1 and a lower support cover 5 on one side of the conveying mechanism 3, an X-ray fluoroscopy box 6 on the other side of the conveying mechanism 3, a display screen 7 fixed to the front of the X-ray fluoroscopy box 6, an X-ray fluorometer 8 fixed inside the X-ray fluoroscopy box 6, and a blowing mechanism 2 located inside the upper support cover 1 and the blowing mechanism 2.
[0031] In this embodiment: the purging mechanism 2 includes a fixed bracket 21, which is fixed inside the lower support cover 5. A rotating ring 22 is provided in the middle of the fixed bracket 21. The rotating ring 22 has a hollow structure inside, and an irradiation camera 25 is fixed on the upper and lower sides of the inner ring of the rotating ring 22. Multiple nozzles 24 are fixed on the front and rear sides of the inner ring of the rotating ring 22. An air inlet pipe 23 for supplying air to its interior is fixed on the upper end of the rotating ring 22. A gear 26 is provided on the lower side of the rotating ring 22. A drive motor 27 is fixedly provided on the input end of the gear 26. Teeth for meshing with the gear 26 are provided on the lower side of the rotating ring 22, and annular grooves are provided on both sides of the rotating ring 22. Annular guide rails 28 for cooperating with the upper side of the annular groove of the rotating ring 22 are fixed on the front and rear sides of the upper support cover 1. An arc-shaped block for cooperating with the lower side of the annular groove of the rotating ring 22 is provided in the middle of the fixed bracket 21. The rotating part of the drive motor 27 drives the gears. The wheel 26 rotates back and forth alternately. The gear 26 engages with the teeth on the bottom side of the rotating ring 22 to make the rotating ring 22 rotate back and forth alternately. At this time, the annular guide rail 28 inside the upper support cover 1 provides sliding support for the upper side of the annular groove of the rotating ring 22, and the arc-shaped block in the middle of the fixed bracket 21 provides sliding support for the lower side of the annular groove of the rotating ring 22, thereby preventing the rotating ring 22 from tipping over during the back and forth alternating rotation. At the same time, compressed air is sent into the hollow structure inside the rotating ring 22 through the air inlet pipe 23. The compressed air blows through multiple nozzles 24 inside the rotating ring 22 to sweep the surface of the packaged staple food, thereby removing foreign objects that may be attached to the packaging surface. Meanwhile, the back and forth alternating rotation of the rotating ring 22 drives the two illumination cameras 25 to swing back and forth to take pictures, thereby facilitating multi-angle photographic inspection of the packaged staple food.
[0032] In this embodiment: the conveying mechanism 3 includes a frame 37, inside which a first conveyor belt 33 and a second conveyor belt 36 are respectively provided. The first conveyor belt 33 is located on one side of the second conveyor belt 36. Each first conveyor belt 33 is provided with two first conveyor rollers 32. A first conveyor motor 31 is fixedly installed at the input end of the first conveyor roller 32. Each second conveyor belt 36 is provided with two second conveyor rollers 35. A second conveyor motor 34 is fixedly installed at the input end of the second conveyor roller 35. The first conveyor motor 31 drives the first conveyor rollers 32 to rotate. The rotation of the first conveyor rollers 32 drives the second conveyor belt 36 to rotate inside the frame 37, thereby conveying the packaged staple food dishes into the upward support cover 1. At the same time, the second conveyor motor 34 drives the second conveyor rollers 35 to rotate. The rotation of the second conveyor rollers 35 drives the second conveyor belt 36 to rotate, thereby receiving the staple food dishes sent out from the first conveyor belt 33 and conveying them to the pushing mechanism 4 and below the X-ray box 6.
[0033] In this embodiment: the feeding mechanism 4 includes a discharge slide 43, which is fixed at the middle position of the front side of the frame 37. A push plate 42 is provided on the rear side of the discharge slide 43. Two symmetrical push cylinders 41 are fixed on the rear side of the push plate 42. A side plate is fixed at the middle position of the rear side of the frame 37, and the fixed parts of the two push cylinders 41 are fixedly connected to the side plate. The push plate 42 is pushed forward along the top side of the second conveyor belt 36 by the extension and retraction parts of the two push cylinders 41, and then the staple food with foreign objects is pushed into the discharge slide 43, so that the dishes with foreign objects detected by the irradiation camera 25 and the dishes with printing errors on the packaging can be kicked out.
[0034] Working principle: In use, the packaged staple food is first placed on one side of the top of the first conveyor belt 33. At this time, the first conveyor motor 31 drives the first conveyor roller 32 to rotate. The rotation of the first conveyor roller 32 drives the second conveyor belt 36 to rotate inside the frame 37, thereby conveying the packaged staple food into the upward support cover 1. At the same time, the second conveyor motor 34 drives the second conveyor roller 35 to rotate. The rotation of the second conveyor roller 35 drives the second conveyor belt 36 to rotate, thereby receiving the staple food sent out from the first conveyor belt 33 and conveying it to the pushing mechanism 4 and below the X-ray box 6.
[0035] After the packaged staple food enters the upper support cover 1, the rotating part of the drive motor 27 drives the gear 26 to rotate back and forth alternately. The gear 26 and the teeth on the bottom side of the rotating ring 22 make the rotating ring 22 rotate back and forth alternately. At this time, the annular guide rail 28 inside the upper support cover 1 provides sliding support for the upper side of the annular groove of the rotating ring 22, and the arc-shaped block in the middle of the fixed bracket 21 provides sliding support for the lower side of the annular groove of the rotating ring 22, so as to prevent the rotating ring 22 from tipping over during the back and forth alternating rotation. At the same time, the air inlet pipe 23 sends compressed air into the hollow structure inside the rotating ring 22. The compressed air blows through multiple nozzles 24 inside the rotating ring 22 to sweep the surface of the staple food packaging, thereby removing foreign objects that may be attached to the packaging surface. Meanwhile, the back and forth alternating rotation of the rotating ring 22 drives two irradiation cameras 25 to swing back and forth around the staple food as the center to take pictures, which facilitates multi-angle and multi-position photography and inspection of the packaged staple food.
[0036] After the main dishes are photographed and inspected, the main dishes are moved by the rotation of the second conveyor belt 36. When the main dishes containing foreign objects move to the front of the push plate 42, the push plate 42 is pushed forward along the top side of the second conveyor belt 36 by the extension and retraction parts of the two push cylinders 41. Then the main dishes with foreign objects are pushed into the discharge chute 43, so that the dishes with foreign objects and the dishes with printing errors on the packaging can be kicked out by the photo-screening camera 25.
[0037] When the problematic staple food is moved into the X-ray fluoroscopy box 6, the X-ray fluoroscopy instrument 8 takes a picture of the staple food to detect whether there are foreign objects inside the staple food. At the same time, the X-ray fluoroscopy instrument 8 will display the transmitted content on the display screen 7. When the X-ray fluoroscopy instrument 8 detects a staple food with a foreign object, the entire first conveyor belt 33 and the second conveyor belt 36 will stop rotating and conveying.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
