Description

Technical Field

[0001] This utility model belongs to the field of food testing technology, specifically relating to a food safety toxin analysis device. Background Technology

[0002] Mycotoxins are metabolic products produced by fungi growing in food or feed. They are harmful to humans and animals, especially food. After food production and processing, it is necessary to test for mycotoxins to ensure that the mycotoxin content in the food meets the standards. However, existing food mycotoxin testing benches are not convenient for testing multiple samples at the same time, which is not conducive to rapid sample testing and reduces the working efficiency of the bench.

[0003] For example, Chinese patent document publication number CN216678308U discloses a test bench for detecting mycotoxins in food, including a platform assembly, a placement box, support legs, and a bracket assembly. In this invention, the platform assembly allows for the creation of multiple test slots on the front side of the workbench, where multiple sample trays are placed. This facilitates simultaneous testing of multiple samples without interference, enabling rapid sample detection and improving the efficiency of the test bench. The bracket assembly places sample bottles in slots and corresponding bottom grooves, ensuring the bottles remain upright and stable, preventing spillage. The socket box contains a power outlet for connecting to mains power, further improving the efficiency of the testing equipment.

[0004] The above application still has shortcomings. Most existing food toxin detection methods use reagent reaction detection. This method is difficult for staff to control the amount of reaction liquid dripping, which can easily lead to inaccurate food toxin detection results. Moreover, the food toxin detection efficiency is low and cannot meet the needs of staff to test food processing.

[0005] Therefore, a food safety toxin analysis device is needed to solve the problems of inaccurate detection of food droplet reaction liquid and low detection efficiency in existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide a food safety toxin analysis device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a food safety toxin analysis device, comprising a frame, the frame further comprising a mounting plate, the mounting plate being fixed to the top side wall of the frame, two symmetrically distributed mounting sleeves being fixed to one side wall of the mounting plate, both mounting sleeves having a vertically arranged drip tube fixed inside, the drip tube being provided with a drip assembly, a rotating rod being rotatably connected to the top side wall of the frame, a bearing plate being tightly fitted to the outer surface of the rotating rod, a plurality of circumferentially distributed sample tubes being clamped to one side wall of the bearing plate, the drip tube being located directly above the sample tubes, and an adjustment assembly adapted to the rotating rod being provided on one side of the frame.

[0008] As a further embodiment of this utility model, the dripping assembly includes an end sleeve connected to the top end of the dripping tube. A nut sleeve is fixed at the center of the end sleeve. A threaded rod inserted into the dripping tube is threadedly connected to the nut sleeve. A piston plate that fits tightly against the inner wall of the dripping tube is fixed to one end of the threaded rod located inside the dripping tube. An end rotating plate is fixed to one end of the threaded rod located outside the dripping tube.

[0009] As a further embodiment of this utility model, an indicator mark is provided on the top surface of the end plate, and a vertically arranged upright plate is fixed on the top surface of the mounting plate. An indicator plate arranged along the height direction of the upright plate is fixed on the side of the upright plate near the end plate. The number of rotations of the threaded rod is indicated by the cooperation of the indicator plate and the indicator mark.

[0010] As a further embodiment of this utility model, the adjustment assembly includes a drive shaft, which is rotatably connected to one side wall of the frame. A servo motor is fixed to one side wall of the frame. One end of the output shaft of the servo motor is coaxially fixed to the drive shaft. An incomplete gear is fastened to the outer surface of the drive shaft, and a spur gear is fastened to the outer surface of the rotating rod. The incomplete gear meshes with the spur gear.

[0011] As a further embodiment of this utility model, the central axis of the bearing disk is collinear with the central axis of the rotating rod, and a through hole is provided on one side wall of the bearing disk.

[0012] As a further embodiment of this utility model, the length of the threaded rod is greater than the length of the dripping tube, and the central axis of the threaded rod is collinear with the central axis of the dripping tube.

[0013] As a further embodiment of this utility model, the end sleeve is threadedly connected to the outer wall of the dripping tube.

[0014] As a further embodiment of this utility model, a rubber sheet is fixed on the inner sidewall. The rubber sheet is located at the bottom of the drip tube. Multiple rubber sheets are provided and arranged in a ring. The edges of two adjacent rubber sheets are pressed together.

[0015] Compared with the prior art, the food safety toxin analysis device provided by this utility model has at least the following beneficial effects:

[0016] 1. By holding the end plate and rotating it a fixed number of times, the end plate drives the threaded rod downwards, which in turn moves the piston plate downwards inside the dripping tube. The dripping tube contains a reaction solution, which is quantitatively expelled by the piston plate. This allows a relatively precise amount of reaction solution to drip into the sample tube after being subjected to pressure. This method is used by staff to test food samples for toxin detection. It can accurately control the dripping of the reaction solution into the sample tube for toxin detection. For staff, it makes the detection of dripping reaction solution more precise and reduces the impact of inaccurate dripping of reaction solution on the toxin detection results. The structure is relatively simple and highly practical. Initially, the indicator mark is aligned with the indicator plate. By rotating the end plate, when the indicator mark is aligned with the indicator plate again, it indicates one rotation. The threaded rod drives the piston plate downwards by a certain displacement, allowing a relatively precise amount of reaction solution to be expelled from the dripping tube and dripped into the sample tube after being subjected to pressure.

[0017] 2. When the piston plate does not push the reaction liquid inside the dripping tube, multiple rubber sheets press against each other and close, sealing the bottom outlet of the dripping tube to prevent the reaction liquid inside the dripping tube from dripping out.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-6 This utility model provides a food safety toxin analysis device, including a frame 1, and a mounting plate 2. The mounting plate 2 is fixed to the top side wall of the frame 1. Two symmetrically distributed mounting sleeves 3 are fixed to one side wall of the mounting plate 2. A vertically arranged drip tube 4 is fixed inside both mounting sleeves 3. A drip assembly 5 is provided on the drip tube 4. A rotating rod 6 is rotatably connected to the top side wall of the frame 1. A bearing plate 7 is tightly fitted onto the outer surface of the rotating rod 6. Multiple circumferentially distributed sample tubes 8 are clamped to one side wall of the bearing plate 7. The drip tube 4 is located directly above the sample tubes 8. An adjustment component 9 adapted to the rotating rod 6 is provided on one side of the frame 1; the drip component 5 can accurately control the reaction liquid to drip into the sample tube 8 for toxin detection. For staff, the detection of dripping reaction liquid is more accurate, reducing the impact of inaccurate reaction liquid dripping on the toxin detection results. The structure is relatively simple, practical, and easy to clean the drip tube 4 later. By using the sample tube 8 to store food samples, not only can the types of samples stored be increased, but it is also convenient for staff to take and place the sample tube 8, which has good practicality.

[0027] Further as Figure 1 , Figure 2 and Figure 5As shown, it is worth noting that the dripping assembly 5 includes an end sleeve 54 connected to the top end of the dripping tube 4. A nut sleeve 55 is fixed at the center of the end sleeve 54. A threaded rod 51 inserted into the dripping tube 4 is threadedly connected to the nut sleeve 55. A piston plate 53, which fits tightly against the inner wall of the dripping tube 4, is fixed to one end of the threaded rod 51 located inside the dripping tube 4. An end rotating plate 52 is fixed to the other end of the threaded rod 51 located outside the dripping tube 4. By holding the end rotating plate 52 and rotating it a fixed number of times, the end rotating plate 52 drives the threaded rod 51 to move... The piston plate 53 moves downwards inside the dripping tube 4, which contains the reaction liquid. The piston plate 53 presses out a precise amount of the reaction liquid from the dripping tube 4, causing it to drip into the sample tube 8. This allows staff to test food samples for toxin detection. The system can accurately control the amount of reaction liquid dripping into the sample tube 8 for toxin detection. For staff, the detection of dripping reaction liquid is more precise, reducing the impact of inaccurate dripping amount on toxin detection results. The structure is relatively simple and highly practical.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that an indicator mark 11 is provided on the top surface of the end plate 52, and a vertically arranged upright plate 13 is fixed on the top surface of the mounting plate 2. An indicator plate 12 is fixed on the side of the upright plate 13 near the end plate 52, arranged along the height direction of the upright plate 13. The indicator plate 12 and the indicator mark 11 work together to provide auxiliary indication of the number of rotations of the threaded rod 51. Initially, the indicator mark 11 is aligned with the indicator plate 12. When the end plate 52 is rotated, and the indicator mark 11 is aligned with the indicator plate 12 again, it indicates that the end plate 52 has rotated one revolution. The threaded rod 51 drives the piston plate 53 to move down by a certain displacement, so that the reaction liquid inside the dripping tube 4 can be squeezed out more accurately and quantitatively, and the more quantitative reaction liquid drips into the sample tube 8 after being subjected to force.

[0029] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the adjustment component 9 includes a drive shaft 91, which is rotatably connected to one side wall of the frame 1. A servo motor 92 is fixed to one side wall of the frame 1. One end of the output shaft of the servo motor 92 is coaxially fixed to the drive shaft 91. An incomplete gear 93 is fastened to the outer surface of the drive shaft 91, and a spur gear 94 is fastened to the outer surface of the rotating rod 6. The incomplete gear 93 and the spur gear 94 are meshed together. When food toxin testing is required, the food samples are first classified and stored in each sample tube 8. Driven by the servo motor 92, the drive shaft 91 rotates synchronously, which drives the incomplete gear 93 to rotate synchronously. Utilizing the meshing transmission effect of the incomplete gear 93 and the spur gear 94, the rotating rod 6 rotates intermittently after being subjected to force, thereby driving the bearing plate 7 to rotate synchronously, so that multiple sample tubes 8 are continuously transferred to the area directly below the dropper 4.

[0030] Further as Figure 5 and Figure 6 As shown, it is worth noting that a rubber sheet 14 is fixed on the inner wall of the dripping tube 4. The rubber sheet 14 is located at the bottom of the dripping tube 4. Multiple rubber sheets 14 are arranged in a ring, and the edges of two adjacent rubber sheets 14 are pressed together. When the piston plate 53 does not push the reaction liquid inside the dripping tube 4, the multiple rubber sheets 14 press together and close, sealing the bottom outlet of the dripping tube 4 to prevent the reaction liquid inside the dripping tube 4 from dripping out. When the piston plate 53 pushes the reaction liquid inside the dripping tube 4, the liquid pushes the rubber sheet 14 to deform elastically, and some of the liquid inside the dripping tube 4 is discharged through the gap between two adjacent rubber sheets 14, adding the reaction liquid into the sample test tube 8.

[0031] This solution includes the following working process: Food samples are categorized and stored in individual sample tubes 8. Driven by a servo motor 92, the drive shaft 91 rotates synchronously, causing the incomplete gear 93 to rotate synchronously. Utilizing the meshing transmission between the incomplete gear 93 and the spur gear 94, the rotating rod 6 rotates intermittently under force, thereby driving the supporting plate 7 to rotate synchronously. This allows multiple sample tubes 8 to be continuously transferred to the area directly below the dripping tube 4. Initially, the indicator mark 11 is aligned with the indicator plate 12. By rotating the end plate 52, when the indicator mark 11 and the indicator plate 12 are aligned again, it indicates that the end plate is rotated. When plate 52 rotates one revolution, it indicates that the threaded rod 51 drives the piston plate 53 to move downward by a certain amount of displacement, so that the reaction liquid inside the dripping tube 4 can be squeezed out more accurately and quantitatively. By holding the end plate 52 and rotating the end plate 52 a fixed number of revolutions, the end plate 52 drives the threaded rod 51 to rotate downward, thereby driving the piston plate 53 to move downward inside the dripping tube 4. The dripping tube 4 contains the reaction liquid, and the piston plate 53 squeezes out the reaction liquid in the dripping tube 4 in a quantitative manner, so that a relatively quantitative amount of reaction liquid drips into the sample test tube 8 after being subjected to force, and the staff conducts toxin detection on the food sample.

[0032] Further as Figure 2 and Figure 3 As shown, it is worth noting that the central axis of the bearing plate 7 is collinear with the central axis of the rotating rod 6, and a through hole 10 is provided on one side wall of the bearing plate 7.

[0033] Further as Figure 1 and Figure 3 As shown, it is worth noting that the support plate 7 can effectively support the sample tube 8, ensuring the stability of the sample tube 8 when the support plate 7 is in operation.

[0034] Further as Figure 2 and Figure 5 As shown, it is worth noting that the length of the threaded rod 51 is greater than the length of the dripping tube 4, and the central axis of the threaded rod 51 is collinear with the central axis of the dripping tube 4.

[0035] Further as Figure 5 As shown, it is worth noting that the end sleeve 54 is threadedly connected to the outer wall of the dripping tube 4; when the reaction liquid inside the dripping tube 4 is consumed, the end sleeve 54 can be removed by rotating it, thereby opening the top opening of the dripping tube 4, making it convenient to add reaction liquid into the dripping tube 4.

[0036] The servo motor 92 can be purchased from the market. The servo motor 92 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
