Description
Technical Field
[0001] The utility model relates to the technical field of food detection, in particular to a food safety risk pre-screening device. Background Art
[0002] Food safety risk testing is an important means of ensuring food safety. It primarily utilizes scientific techniques and methods to detect and analyze various potential hazards in food. This includes testing for chemical contaminants in food, such as pesticide residues, veterinary drug residues, and heavy metals, to determine whether they exceed safety standards; testing for biological hazards, such as bacteria, viruses, and parasites, to prevent foodborne illnesses caused by these microorganisms; and testing for compliance with food additive regulations. Food safety risk testing can promptly identify potential safety hazards in food, providing regulatory authorities with a basis for decision-making and encouraging food manufacturers to strictly control production processes, ensuring food safety and reliability from the source of production to the consumer's table, and safeguarding the public's health and safety.
[0003] However, some existing food safety risk pre-screening devices are unable to effectively and precisely fix the position of the food when the detection probe needs to be pointed downward to perform the inspection. During the inspection process, the food can shift position due to factors such as slight vibrations, external interference, or the movement of the conveyor belt. This positional instability directly affects the contact accuracy between the detection probe and the food, making it impossible for the detection probe to accurately detect specific parts of the food. Therefore, to address these shortcomings, a food safety risk pre-screening device is proposed to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1 to 3 The utility model provides an embodiment: a food safety risk pre-screening device, comprising an outer frame 1, which serves as the main frame of the entire food safety risk pre-screening device and provides a stable installation and operation space for each structure. A driving assembly is provided on the top of the outer frame 1, and the driving assembly includes a cylinder 2. The bottom of the cylinder 2 is installed on the top of the outer frame 1. The cylinder 2 is the core power source of the driving assembly. The output end of the cylinder 2 is fixedly connected to a push rod 3, and the bottom of the push rod 3 is fixedly connected to a mounting plate 4. A plurality of detection probes 5 are installed on the bottom of the mounting plate 4. The mounting plate 4 is an installation platform for the detection probes 5. The detection probes 5 are the key structure of the food safety risk pre-screening device, which is mainly used for detecting food. The detection probes 5 are usually made of highly sensitive sensor materials and can quickly and accurately detect various safety risk indicators in food.
[0033] Reference Figures 2 to 4The front and rear sides of the drive assembly are fixedly connected with sleeves 6, and the interiors of the two sleeves 6 are slidably connected with sliding disks 7. The main function of the sleeves 6 is to provide guidance and support for the sliding disks 7 and the connecting rods 9. Springs 1-8 are provided inside the two sleeves 6. One end of the spring 1-8 is fixedly connected to the interior of the sleeve 6, and the other end of the spring 1-8 is fixedly connected to the exterior of the sliding disk 7. The far sides of the two sliding disks 7 are fixedly connected to the connecting rod 9. The exterior of the connecting rod 9 is slidably connected to the interior of the sleeve 6. The far sides of the two connecting rods 9 are fixedly connected to right-angle rods 10. When the right-angle rods 10 drive the limit disk 11 to slide in the clamping plate 12, the springs 1-8 are compressed, generating elastic force. The near sides of the two right-angle rods 10 are fixedly connected to the limit disk 11. The function of the limit disk 11 is to slide in the clamping plate 12 to limit the movement range of the clamping plate 12. The outside of the two limit plates 11 are slidably connected to the clamping plates 12, the outside of the right-angle rod 10 is slidably connected to the inside of the clamping plates 12, and the inside of the two clamping plates 12 are provided with limit slots 13. The front and rear sides of the inner part of the outer frame 1 are fixedly connected to triangular blocks 14, and the bottom of the right-angle rod 10 is in contact with the top of the triangular block 14;
[0034] Two guide rods 15 are slidably connected to the interior of each triangular block 14. The side of the guide rod 15 closest to the detection probe 5 is fixedly connected to the side of the clamping plate 12 away from the detection probe 5. During operation, the bottom of the right-angle rod 10 contacts the top of the triangular block 14. When the mounting plate 4 drives the sleeve 6 and connecting rod 9 downward, the right-angle rod 10 also moves downward, moving along the inclined surface of the triangular block 14, thereby driving the limit plate 11 to slide within the clamping plate 12, so that the clamping plate 12 clamps and fixes the food. A conveyor belt 16 is provided on the inner bottom side of the outer frame 1. The function of the conveyor belt 16 is to transport food and achieve continuous food testing.
[0035] Reference Figures 3 to 5 Two fixed shafts 17 are fixedly connected to the left side of the top of the conveyor belt 16. The outside of the two fixed shafts 17 is rotatably connected to a rotating ring 18. The function of the rotating ring 18 is to drive the toggle plate 20 to rotate under the pressure of the food, thereby correcting the food's deviation. The top of the two fixed shafts 17 is fixedly connected to a fixed disk 19. The right side of the two rotating rings 18 is fixedly connected to a toggle plate 20. The bottom of the toggle plate 20 is slidably connected to the top of the conveyor belt 16. When the food is transported on the conveyor belt 16, the food will squeeze the toggle plate 20, causing the toggle plate 20 to drive the rotating ring 18 to rotate outside the fixed shaft 17, thereby correcting the food's deviation. The far side of the two toggle plates 20 is fixedly connected to a movable ball 21. The function of the movable ball 21 is to drive the sliding shaft 22 to slide inside the fixed plate 25 when the toggle plate 20 rotates.
[0036] Reference Figure 1 、 Figure 4 and Figure 5 The two movable balls 21 are fixedly connected to the opposite side of each other with a sliding shaft 22. The outside of each sliding shaft 22 is fixedly connected to a fixing ring 23. The outside of each sliding shaft 22 is sleeved with a spring 24. The function of the spring 24 is to provide elastic force for the sliding shaft 22 to correct the deviation of the food. The top of the conveyor belt 16 is fixedly connected to two fixed plates 25. The outside of the sliding shaft 22 is slidably connected to the inside of the fixed plate 25. The opposite side of the two sliding shafts 22 is fixedly connected to a limit plate 26. The function of the limit plate 26 is to limit the movement range of the sliding shaft 22 and prevent the sliding shaft 22 from falling out of the fixed plate 25. The right side of the conveyor belt 16 is fixedly connected to an inclined plate 27. The function of the inclined plate 27 is to guide the inspected food from the conveyor belt 16 to the collection device. The bottom of the inclined plate 27 is fixedly connected to a support plate 28. The front side of the outer frame 1 is provided with a control panel 29. The control panel 29 is the control center of the food safety risk pre-screening device. Its main function is to control and operate the various components of the device. The control panel 29 typically consists of electronic components and a display screen, providing excellent human-computer interaction. Through the control panel 29, the user can set the device's operating parameters, such as the speed of the conveyor belt 16, the pressure of the air cylinder 2, and the detection time of the detection probe 5. The control panel 29 also displays the device's operating status and detection results in real time, facilitating user monitoring and management.
[0037] Working principle: When using this food safety risk pre-screening device, you can first place the food on the top of the conveyor belt 16 and use the conveyor belt 16 to transport the food. As the food is transported, the toggle plate 20 will be squeezed so that the toggle plate 20 drives the rotating ring 18 to rotate outside the fixed shaft 17. As the toggle plate 20 rotates, the movable ball 21 will be hinged to the inside of the toggle plate 20, and the sliding shaft 22 will slide inside the fixed plate 25. At this time, the spring 24 will be compressed, so that the elastic force of the spring 24 can be used to correct the food, which can effectively prevent the deviation of the food, thereby ensuring the accuracy of the detection.
[0038] During the transportation process, a random time can be selected to stop, and then the cylinder 2 can be started. The cylinder 2 can drive the push rod 3 and the mounting plate 4 to move downward, and then the detection probe 5 can be moved downward. As the mounting plate 4 moves downward, the sleeve 6 and the connecting rod 9 can drive the right-angle rod 10 to move downward, so that the bottom of the right-angle rod 10 can slide on the top of the triangular block 14, and then the right-angle rod 10 can move along the inclined surface of the triangular block 14. At this time, the limit plate 11 will slide inside the clamping plate 12, and the connecting rod 9 will slide inside the sleeve 6, so that the spring 8 will be compressed, thereby driving the clamping plate 12 to move, and then the food can be clamped and fixed, so that the food can be detected with the help of an object.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
