Description

Technical Field

[0001] This utility model relates to the field of food testing, specifically a food safety testing device. Background Technology

[0002] When storing fragile foods like potato chips, it's common practice to remove the air from the food bags before filling them with inert gas and then sealing them. This extends shelf life and prevents the fragile foods from breaking and affecting quality. However, in actual processing, some food bags are often filled with too little gas, failing to meet the required standards. Insufficient gas can easily damage the food inside. When substandard food bags are mixed with intact ones, the quality of that batch of products is reduced. To prevent this quality decline, the substandard food bags must be removed.

[0003] Existing food safety testing methods often rely on manual pressing and screening to check for leaks in food bags. This method is not only inefficient, but also prone to missed or incorrect screenings after prolonged manual testing, which can affect product quality. Utility Model Content

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] The present invention provides the following preferred embodiments: Examples, such as Figures 1-8 As shown, a food safety testing device includes a base plate 1, a transport machine 2, a testing mechanism, and a collection mechanism. The transport machine 2 is located on top of the base plate 1. The detection mechanism includes a transmission belt 3, a rotating assembly, a lifting assembly, a reset assembly, and a ranging assembly. The lifting assembly is located on both sides of the conveyor 2, the rotating assembly is located on the lifting assembly, the transmission belt 3 is located on the rotating assembly, the reset assembly is located between the rotating assembly and the lifting assembly, and the ranging assembly is located above the rotating assembly. The collection mechanism includes a lever 8 and a toggle assembly. The toggle assembly is located on one side of the conveyor 2, and the lever 8 is mounted on the toggle assembly. Multiple rotating wheels are rotatably mounted on one side of the lever 8. It should be noted that the rotation of the multiple rotating wheels is controlled by a drive assembly. When it is necessary to push out unqualified food bags, the drive assembly controls the rotation of the multiple rotating wheels, which in turn move and push out the unqualified food bags. When it is necessary to test the food, the food is placed on the conveyor 2, and the conveyor 2 moves the food bags to below the transmission belt 3.

[0025] like Figures 1-8 As shown, the lifting assembly includes two support frames 4, two movable plates 5, multiple sliders 6 and multiple slide grooves 7. Each support frame 4 is fixedly installed on the top of the base plate 1, and the two support frames 4 are respectively installed on both sides of the conveyor 2. Every two slide grooves 7 are opened on one side of one support frame 4. Each slider 6 is slidably installed inside one slide groove 7. The two movable plates 5 are respectively fixedly installed on multiple sliders 6. When the food bag passes under the conveyor belt 3, because the inside of the food bag is filled with inert gas, the food bag can exert an upward force on the conveyor belt 3, so that the conveyor belt 3 can move upward. When the conveyor belt 3 moves upward, it will drive the moving plates 5 on both sides to move upward at the same time. The moving plates 5 slide upward in the groove 7 opened in the support frame 4 through the slider 6. When sliding, it will drive the mounting plate 16 to move together, so as to facilitate the ranging component to detect the position.

[0026] like Figures 1-8 As shown, the rotating assembly includes a first motor 9, a first gear 10, a second gear 11, and three rotating rollers 12. Each rotating roller 12 is rotatably disposed between two moving plates 5. The first motor 9 is fixedly disposed on one side of one of the moving plates 5. The first gear 10 is rotatably disposed on the side of the moving plate 5 away from the first motor 9, and the first gear 10 is fixedly connected to the output end of the first motor 9. The second gear 11 is fixedly sleeved on one end of one of the rotating rollers 12, and the second gear 11 meshes with the first gear 10. The transmission belt 3 is sleeved on the outer wall of the three rotating rollers 12. When food bags need to be inspected, the controller controls the first motor 9 to rotate, which drives the first gear 10 to rotate. The first gear 10 drives the second gear 11 to rotate, which in turn drives one of the rotating rollers 12 to rotate. The rotating roller 12 drives the transmission belt 3 to rotate, which in turn drives multiple rotating rollers 12 to rotate. The rotation of the transmission belt 3, in conjunction with the conveyor 2, transports the food bags above the conveyor 2. When the food bags pass under the transmission belt 3, because the inside of the food bags is filled with inert gas, the food bags can exert an upward force on the transmission belt 3, which causes the transmission belt 3 to move upward and drive the moving plates 5 on both sides to move.

[0027] like Figures 1-8 As shown, the reset assembly includes multiple springs 13 and multiple telescopic rods 14. Each telescopic rod 14 is disposed inside a slide groove 7, and both ends of each telescopic rod 14 are fixedly connected to the top of the slider 6 and the inner wall of the slide groove 7, respectively. Each spring 13 is sleeved on the outer wall of a telescopic rod 14, and both ends of each spring 13 are fixedly connected to the top of the slider 6 and the inner wall of the slide groove 7, respectively. When the food bag passes through the conveyor belt 3, because the inside of the food bag is filled with inert gas, the food bag can exert an upward force on the conveyor belt 3 when passing through it, thereby causing the conveyor belt 3 to move upward. At this time, the spring 13 located inside the slide groove 7 will be compressed. After the food bag passes the conveyor belt 3, the spring 13 will reset, causing the conveyor belt 3 to descend, which is convenient for the next inspection.

[0028] like Figures 1-8 As shown, the ranging component includes a fixed plate 15, a mounting plate 16, and a distance detector 17. The fixed plate 15 is fixedly installed between two support frames 4, the mounting plate 16 is fixedly installed between two movable plates 5, and the distance detector 17 is fixedly installed at the bottom of the fixed plate 15. When detecting the amount of gas filled inside the food bag, the distance detector 17 detects the distance between itself and the mounting plate 16, thereby detecting the distance the food bag pushes upward against the transmission belt 3, and sends an electrical signal to the controller. The controller determines whether the distance the mounting plate 16 moves meets the standard. When the distance detector 17 detects that the upward distance of the mounting plate 16 is qualified, it determines that the amount of gas introduced into the food bag is qualified. When the distance detector 17 detects that the upward distance of the mounting plate 16 is unqualified, it determines that the amount of gas introduced into the food bag is unqualified. The controller controls the toggle component to work, driving the lever 8 to move and changing the feeding position of the unqualified food bag. When the mounting plate 16 rises, if the food bag below the fixing plate 15 is in good condition and has no air leakage, the food bag will pass through the transmission belt 3.

[0029] like Figures 1-8As shown, the actuating assembly includes a second motor 18, an L-shaped plate 19, a third gear 20, a fourth gear 21, a rotating column 22, a hopper 23, and a stop post 24. The L-shaped plate 19 is fixedly mounted on the top of the base plate 1, the rotating column 22 is rotatably mounted on the top of the L-shaped plate 19, the second motor 18 is fixedly mounted on the bottom of the L-shaped plate 19, the third gear 20 is rotatably mounted on the top of the L-shaped plate 19, and the output end of the second motor 18 is fixedly connected to the third gear 20. The fourth gear 21 is fixedly sleeved on the outer wall of the rotating column 22, and the third gear 20 and the fourth gear 21 mesh with each other. The lever 8 is fixedly connected to the outer wall of the rotating column 22. The hopper 23 is located on one side of the conveyor 2, and the stop post 24 is fixedly mounted on the top of the hopper 23. When the distance detector 17 detects a defective product, it sends an electrical signal to the controller. The controller then controls the second motor 18 to rotate, which in turn drives the third gear 20 to rotate. The third gear 20 then drives the fourth gear 21 to rotate, which in turn drives the rotating column 22 to rotate. The rotating column 22 then drives the lever 8 to rotate until the end of the lever 8 furthest from the rotating column 22 contacts the abutment 24. This control causes multiple rotating wheels to rotate. When a food bag detected as leaking comes into contact with the lever 8, the bag is pulled into the hopper 23 by the rotating wheel on the side of the lever 8 that is in contact with the bag, and by the conveyor 2. The hopper 23 collects the defective food bags, preventing them from mixing with qualified bags and affecting product quality. like Figures 1-8 As shown, the three rotating rollers 12 have different diameters. By setting rotating rollers 12 with different diameters, one end of the transmission belt 3 is tilted, so that the food bag can be better transported between the conveyor 2 and the transmission belt 3.
