Description

Technical Field

[0001] This invention belongs to the field of food testing technology, and specifically relates to a food testing device. Background Technology

[0002] In related technologies, after food packaging is completed, the food needs to be boxed to facilitate subsequent product shipment. After the food is boxed, in order to prevent the food from containing metal foreign objects, it is necessary to perform metal detection on the boxed food using a metal detection device.

[0003] Existing technology (publication number: CN211263421U) discloses a food metal detector, including a detection platform. A rotary motor is fixedly installed on the front of the detection platform near the left end. A first rotating shaft is provided at the rear end of the rotary motor. A drive wheel is fixedly installed around the first rotating shaft. A driven wheel is provided to the right of the drive wheel. A second rotating shaft is provided inside the driven wheel. A conveyor belt is provided between the drive wheel and the driven wheel. A support rod is fixedly installed at the bottom of the detection platform near the corner. Each of the four sets of support rods has a crossbar near the bottom. A sliding plate is installed at the left end of the detection platform. An inner rod is fixedly installed at the upper end of the detection platform. An outer rod is provided on each of the two sets of inner rods. A first bearing plate is fixedly installed between the two sets of outer rods. This design ensures the accuracy of metal detection, has a good height adjustment function, is safe, and can also conveniently separate food containing metal.

[0004] In this existing technology, although it is possible to detect metal in packaged food and determine whether there is metal inside the box, it cannot determine the specific location of the food containing metal. As a result, staff need to test each food item individually, which makes it impossible to replace the food in a short time and affects work efficiency. Summary of the Invention

[0018] The food testing device of the present invention has the following advantages compared with the prior art:

[0019] 1. By using a moving mechanism to move the first detector along the X-axis, an adjusting mechanism to move the second detector along the Y-axis, and a first lifting mechanism to move the third detector along the Z-axis, the first, second, and third detectors can sequentially detect packaged food in different directions. This allows for the precise location of food containing metal without requiring staff to inspect each item individually. This enables the rapid identification and replacement of metal-containing food, improving product efficiency. Furthermore, by positioning a reversing conveyor mechanism between the first, second, and third conveyor mechanisms, the conveying direction of the reversing conveyor can be adjusted to separately transfer metal-containing and metal-free food to the second and third conveyor mechanisms, thus classifying the food for subsequent processing and further enhancing the user experience.

[0020] 2. When the metal detector does not detect any metal in the food, the boxed food removed from the first conveyor mechanism will move to multiple first conveyor wheels. Then, the first shaft will be rotated, causing the first conveyor wheels to rotate, thereby enabling the multiple first conveyor wheels to work together to move the boxed food to the second conveyor mechanism, so that the second conveyor mechanism can move the boxed food to a predetermined position. At this time, the highest point of the second and third conveyor wheels is lower than the highest point of the first conveyor wheels, so the second and third conveyor wheels will not come into contact with the box containing the food, thereby avoiding interference between the second and third conveyor wheels and the box, and thus avoiding damage to the box. When the metal detector detects metal in the food, two second lifting mechanisms are activated, causing multiple second lifting mechanisms to move the third support frame upwards, so that the highest point of the second and third conveyor wheels is higher than the highest point of the first conveyor wheel. Then, the first conveyor mechanism moves the boxed food onto the second and third conveyor wheels. Subsequently, the second and third rotating shafts are rotated simultaneously, causing the second and third rotating shafts to drive the second and third conveyor wheels to rotate respectively. This allows the second and third conveyor wheels to work together to move the boxed food onto the third conveyor mechanism, thereby classifying the food for subsequent processing.

[0021] 3. By simultaneously driving the second and third rotating shafts with the fourth rotating shaft, synchronous rotation of the second and third rotating shafts is achieved, thereby enabling synchronous rotation of the second and third conveyor wheels and improving the efficiency of the second and third conveyor wheels in moving the boxed food. Furthermore, by having the fourth rotating shaft drive the second rotating shaft via the first synchronous wheel, the second synchronous wheel, and the first synchronous belt, and by having the fourth rotating shaft drive the third rotating shaft via the third synchronous wheel, the fourth synchronous wheel, and the second synchronous belt, and by positioning the fourth rotating shaft below the second and third rotating shafts, interference between the fourth rotating shaft and the first rotating shaft can be avoided, while ensuring synchronous rotation of the second and third rotating shafts. This avoids interference between the fourth rotating shaft and the first rotating shaft, ensuring that the third support frame and its internal components can move vertically. Consequently, the second and third conveyor wheels can both fit snugly against the bottom of the food container and avoid direct contact with the food container, thus improving the user experience.

[0022] 4. By connecting two sixth synchronous pulleys to two first rotating shafts respectively, and simultaneously fitting a fourth synchronous belt around the outside of the two fourth synchronous pulleys, when one first rotating shaft rotates, it drives the other first rotating shaft to rotate through the two sixth synchronous pulleys and the fourth synchronous belt, thereby achieving synchronous rotation of the two first rotating shafts; by mounting the first motor frame on the outside of the first support frame, mounting the first motor body on the first motor frame, and connecting the first motor body to the first rotating shaft, the first motor frame supports the first motor body, thereby enabling the first motor body to drive the first rotating shaft to rotate, thus providing power for rotating the first rotating shaft.

[0023] 5. When the metal detector does not detect any metal in the food, the first lead screw is rotated, causing the first baffle to move upward, thereby increasing the distance between the first baffle and the third support frame. This prevents the first baffle from obstructing the boxed food, ensuring that the first conveyor wheel can move the boxed food to the second conveyor mechanism. When the metal detector detects metal in the food, the first lead screw is rotated in the opposite direction, causing the first baffle to move downward, thereby decreasing the distance between the first baffle and the third support frame. This prevents the first baffle from obstructing the boxed food, ensuring that the boxed food remains between the second and third conveyor wheels. This allows the second and third conveyor wheels to work together to move the boxed food to the third conveyor mechanism.

[0024] 6. By installing the first cylinder inside the first support frame, allowing the first output shaft of the first cylinder to pass through the bottom of the second support frame, and connecting the first output shaft of the first cylinder to the third support frame, the first support frame supports the first cylinder. Simultaneously, it enables the first cylinder to drive the first output shaft, moving the third support frame up and down without interfering with the second support frame, thereby adjusting the height of the third support frame. By installing the first guide seat inside the first support frame, installing the first linear bearing inside the first guide seat, and fitting the first linear bearing onto the outside of the first guide rod, the first guide seat guides the first guide rod through the first linear bearing, preventing misalignment between the first guide rod and the third support frame during up and down movement, thus improving the stability of the third support frame's up and down movement.

[0025] 7. By connecting one end of the two connecting rods to the second movable plate and the second baffle to the other end of the two connecting rods, and positioning the second baffle above the third conveying mechanism, when the second movable plate moves, the second movable plate drives the second baffle to move through the two connecting rods. This allows the second baffle to block and position the boxed food conveyed by the third conveying mechanism, ensuring that the boxed food remains in the mounting rack, thus facilitating subsequent food inspection.

[0026] 8. By connecting the guide plate to the second output shaft of the second cylinder, connecting one end of the guide plate to the guide plate, and extending the other end of the guide plate away from the centerline of the third conveying mechanism, the second cylinder can drive the guide plate and guide plate to move, thereby adjusting the distance between the two guide plates and the two guide plates. This allows the two guide plates and the two guide plates to work together to guide the boxed food, so that the centerline of the box coincides with the centerline of the third conveying mechanism, thereby positioning the boxed food for subsequent food inspection.

[0027] 9. By setting the third threaded hole inside the first movable plate and passing the third lead screw through the third threaded hole, the third lead screw is threadedly connected to the first movable plate, thereby rotating the third lead screw to drive the first movable plate to move, and thus adjusting the position of the first detector so that the first detector can detect different positions of the packaged food.

[0028] 10. By setting the fourth threaded hole inside the lifting plate and passing the fourth lead screw through the fourth threaded hole, the fourth lead screw is threadedly connected to the lifting plate. This allows the fourth lead screw to move up and down when the fifth motor body drives the fourth lead screw to rotate, thereby adjusting the height of the lifting plate and the third detector, and enabling the third detector to detect different positions of the packaged food.

[0029] 11. By setting the fifth threaded hole inside the adjusting plate and passing the fifth lead screw through the fifth threaded hole, the fifth lead screw is threadedly connected to the adjusting plate. This allows the fifth lead screw to be rotated, causing the adjusting plate and the third detector to move, thereby adjusting the position of the third detector and enabling the third detector to detect different positions of the packaged food.

Detailed Implementation

[0040] The following are specific implementation cases and appendices. Figures 1 to 8 The present invention will be further described, but the present invention is not limited to these embodiments.

[0041] A food testing device, such as Figure 1 and Figure 2As shown, the food detection device includes: a first conveying mechanism 10, a second conveying mechanism 12, a reversing conveying mechanism 13, a third conveying mechanism 17, a fixed plate 18, a mounting bracket 19, a moving mechanism 20, a first moving plate 21, a first detector 22, an adjusting mechanism 23, an adjusting plate 24, a second detector 25, a first lifting mechanism 26, a lifting plate 27, and a third detector 28; a metal detector 11 is installed on the first conveying mechanism 10; the second conveying mechanism 12 is located on one side of the first conveying mechanism 10, and there is a gap between the second conveying mechanism 12 and the first conveying mechanism 10; the reversing conveying mechanism 13 is located between the first conveying mechanism 10 and the second conveying mechanism 12; the third conveying mechanism 17 is located on one side of the reversing conveying mechanism 13, and the third conveying mechanism 17 is perpendicular to the first conveying mechanism 10; two fixed plates 18 are installed on the third conveying mechanism 10. The third conveying mechanism 17 is mounted on both sides of the mounting frame 19, which is mounted on two fixed plates 18 and is arranged around the outside of the third conveying mechanism 17. The moving mechanism 20 is mounted on the top of the mounting frame 19. The first moving plate 21 is connected to the moving mechanism 20. The first detector 22 is located inside the mounting frame 19 and is connected to the first moving plate 21. The adjusting mechanism 23 is mounted on one inner wall of the mounting frame 19 and is perpendicular to the moving mechanism 20. The adjusting plate 24 is located inside the mounting frame 19 and is connected to the adjusting mechanism 23. The second detector 25 is mounted on the adjusting plate 24. The first lifting mechanism 26 is mounted on the other inner wall of the mounting frame 19. The lifting plate 27 is located inside the mounting frame 19 and is connected to the first lifting mechanism 26. The third detector 28 is mounted on the lifting plate 27.

[0042] By mounting a metal detector 11 on the first conveying mechanism 10, the metal detector 11 can detect whether the boxed food contains metal when the first conveying mechanism 10 conveys the food. By positioning the second conveying mechanism 12 to one side of the first conveying mechanism 10 and the reversing conveying mechanism 13 between the first and second conveying mechanisms 10 and 12, the reversing conveying mechanism 13 can transfer the boxed food from the first conveying mechanism 10 to the second conveying mechanism 12, allowing the second conveying mechanism 12 to transfer the food to a predetermined position. By positioning the third conveying mechanism 17 to one side of the reversing conveying mechanism 13 and perpendicular to the first conveying mechanism 10, the reversing conveying mechanism 13 can change the conveying direction of the boxed food when the metal detector 11 detects metal, thus transferring the boxed food to the third conveying mechanism 17.By installing two fixed plates 18 on both sides of the third conveying mechanism 17 and installing the two sides of the mounting frame 19 on the two fixed plates 18 respectively, the third conveying mechanism 17 supports the mounting frame 19 through the two fixed plates 18, thereby improving the stability of the mounting frame 19 and allowing the mounting frame 19 to be arranged around the outside of the third conveying mechanism 17. By installing the moving mechanism 20 on the top of the mounting frame 19, connecting the first moving plate 21 to the moving mechanism 20, and connecting the first detector 22 to the first moving plate 21, the first moving plate 21 supports the first detector 22, thereby enabling the moving mechanism 20 to drive the first moving plate 21 and the first detector 22 to move, and enabling the first detector 22 to detect different positions of the packaged food to delineate the location range of food containing metal. By installing the adjusting mechanism 23 on an inner wall of the mounting frame 19, connecting the adjusting plate 24 to the adjusting mechanism 23, and installing the second detector 25 on the adjusting plate 24, the first moving mechanism 17 supports the first detector 22. On plate 24, mounting bracket 19 supports adjustment mechanism 23 and second detector 25, enabling adjustment mechanism 23 to move adjustment plate 24 and second detector 25. This allows second detector 25 to detect different locations of packaged food, narrowing down the range of locations containing metal. By installing first lifting mechanism 26 on another inner wall of mounting bracket 19, connecting lifting plate 27 to first lifting mechanism 26, and installing third detector 28 on lifting plate 27, mounting bracket 19 supports first lifting mechanism 26, and lifting plate 27 supports third detector 28. This allows first lifting mechanism 26 to move lifting plate 27 and third detector 28 up and down, adjusting the height of third detector 28. This allows third detector 28 to detect different locations of packaged food, further narrowing down the range of locations containing metal, ensuring the precise location of metal-containing food.

[0043] In actual use, the packaged food is first placed on the first conveyor mechanism 10. Then, the first conveyor mechanism 10 is activated, causing it to move the food through the metal detector 11, which then detects whether the food contains metal. If the food does not contain metal, the reversing conveyor mechanism 13 is activated, moving the food to the second conveyor mechanism 12, which then moves it to a predetermined position. If the food contains metal, the reversing conveyor mechanism 13 is adjusted, and then activated again, moving the food to the third conveyor mechanism 17. The third conveyor mechanism 17 is then activated, moving the food into the mounting rack 19. The third conveying mechanism 17 is stopped, causing the food to remain within the mounting rack 19. Then, the moving mechanism 20 is activated, causing the first detector 22 to move along the X-axis (perpendicular to the conveying direction of the third conveying mechanism 17), allowing the first detector 22 to detect different positions of the boxed food to determine the range containing the metal. Next, the adjusting mechanism 23 is activated, causing the second detector 25 to move along the Y-axis (parallel to the conveying direction of the third conveying mechanism 17), allowing the second detector 25 to detect different positions of the boxed food to narrow down the range containing the metal. Finally, the first lifting mechanism 26 is activated, causing the first lifting mechanism 26 to move the third detector 28 along the Z-axis (height direction), allowing the third detector 28 to detect different positions of the boxed food, further narrowing down the range containing the metal, and ultimately locating the specific position containing the metal.

[0044] By employing the above structure, the moving mechanism 20 drives the first detector 22 along the X-axis, the adjusting mechanism 23 drives the second detector 25 along the Y-axis, and the first lifting mechanism 26 drives the third detector 28 along the Z-axis. This allows the first detector 22, the second detector 25, and the third detector 28 to sequentially detect packaged food in different directions, thereby locating the specific location of food containing metal. This eliminates the need for staff to inspect each food item individually, enabling the rapid identification and replacement of metal-containing foods, thus improving product efficiency. Furthermore, by positioning the reversing conveyor 13 between the first conveyor 10, the second conveyor 12, and the third conveyor 17, the conveying direction of the reversing conveyor 13 can be adjusted to separately transfer metal-containing and metal-free foods to the second conveyor 12 and the third conveyor 17, respectively. This achieves food classification, facilitating subsequent food processing and further enhancing the user experience.

[0045] Specifically, the first conveyor belt mechanism includes a first conveyor frame, a first conveyor roller, and a first conveyor belt; two first conveyor rollers are rotatably connected to both ends of the first conveyor frame, and the first conveyor belt is fitted on the outside of the two first conveyor rollers so that the two first conveyor rollers cooperate to support the first conveyor belt, so that when the driving device drives one of the first conveyor rollers to rotate, the two first conveyor rollers cooperate to drive the first conveyor belt to move, thereby driving the boxed food placed on the first conveyor belt to move.

[0046] Specifically, the second conveyor belt mechanism includes a second conveyor frame, a second conveyor roller, and a second conveyor belt; the two second conveyor rollers are rotatably connected to both ends of the second conveyor frame, and the second conveyor belt is fitted on the outside of the two second conveyor rollers so that the two second conveyor rollers cooperate to support the second conveyor belt, so that when the drive device drives one of the second conveyor rollers to rotate, the two second conveyor rollers cooperate to drive the second conveyor belt to move, thereby driving the boxed food placed on the second conveyor belt to move.

[0047] Specifically, the third conveyor belt mechanism includes a third conveyor frame, a third conveyor roller, and a third conveyor belt; two third conveyor rollers are rotatably connected to both ends of the third conveyor frame, and the third conveyor belt is fitted on the outside of the two third conveyor rollers so that the two third conveyor rollers cooperate to support the third conveyor belt, so that when the drive device drives one third conveyor roller to rotate, the two third conveyor rollers cooperate to drive the third conveyor belt to move, thereby driving the boxed food placed on the third conveyor belt to move.

[0048] In embodiments of the present invention, such as Figures 3 to 8As shown, the reversing conveyor mechanism 13 includes: a first support frame 131, a second support frame 132, a first rotating shaft 133, a first conveyor wheel 134, a third support frame 135, a hanger 136, a second rotating shaft 137, a second conveyor wheel 138, a support plate 139, a third rotating shaft 140, a third conveyor wheel 141, and a second lifting mechanism 142; at least two first support frames 131 are installed between the first conveyor mechanism 10 and the second conveyor mechanism 12; the second support frame 132 is U-shaped, and the second... Support frame 132 is simultaneously mounted on at least two first support frames 131; two first rotating shafts 133 are located inside the second support frame 132, and both first rotating shafts 133 are rotatably connected to the second support frame 132; at least two first transmission wheels 134 are fitted onto the outside of the first rotating shafts 133; the third support frame 135 is U-shaped, placed inside the second support frame 132, and the second support frame 132 and the third support frame 135 are staggered; the hanger 136 is L-shaped, and the hanger... A frame 136 is mounted on an inner wall of a third support frame 135; two second rotating shafts 137 are located inside the hanger 136, with both ends of the two second rotating shafts 137 rotatably connected to the hanger 136 and the third support frame 135 respectively, and the second rotating shafts 137 are perpendicular to the first rotating shaft 133; two second conveying wheels 138 are respectively fitted onto the outer sides of the two second rotating shafts 137; two support plates 139 are mounted on the bottom of the third support frame 135, with the two support plates 139 located between the two first rotating shafts 133; both ends of two third rotating shafts 140 are rotatably connected to the two support plates 139 respectively, and the third rotating shafts 140 are perpendicular to the first rotating shafts 133; two third conveying wheels 141 are respectively fitted onto the outer sides of the two third rotating shafts 140; at least two second lifting mechanisms 142 are respectively mounted inside at least two first support frames 131, and at least two second lifting mechanisms 142 are simultaneously connected to the third support frame 135; wherein the second conveying wheels 138 and the third conveying wheels 141 are at the same height.

[0049] By installing at least two first support frames 131 between the first conveying mechanism 10 and the second conveying mechanism 12, and simultaneously installing a U-shaped second support frame 132 on the at least two first support frames 131, the at least two first support frames 131 cooperate to support the second support frame 132, thereby improving the stability of the second support frame 132. By simultaneously rotatably connecting two first rotating shafts 133 to the second support frame 132, and fitting multiple first conveying wheels 134 onto the outside of the first rotating shafts 133, the second support frame 132 supports the two first rotating shafts 133, thereby rotating the first rotating shafts 133 to drive the multiple first conveying wheels 134 to rotate. Thus, when the boxed food is placed on the first conveying wheel 134, the multiple first conveying wheels 134 cooperate to move the boxed food onto the second conveying mechanism 12. By placing a U-shaped third support frame 135 inside the second support frame 132, and staggering the second support frame 132 and the third support frame 135, the second support frame 132 can support the third support frame 135, thereby allowing the third support frame 135 to move up and down within the second support frame 132. By welding an L-shaped hanger 136 onto an inner wall of the third support frame 135, and rotatably connecting the two ends of the two second rotating shafts 137 to the hanger 136 and the third support frame 135 respectively, the hanger 136 and the third support frame 135 cooperate to support the two second rotating shafts 137, thereby allowing the two second rotating shafts 137 to rotate within the hanger 136. By respectively mounting two second transmission wheels 138 on the two... The second rotating shaft 137 is positioned on the outside of the first rotating shaft 133 and perpendicular to it, so that the second rotating shaft 137 can rotate the second conveyor wheel 138. Two support plates 139 are welded to the bottom of the third support frame 135, and the two ends of the two third rotating shafts 140 are rotatably connected to the two support plates 139 respectively. The two third conveyor wheels 141 are respectively fitted onto the outside of the two third rotating shafts 140, so that the two support plates 139 cooperate to support the two third rotating shafts 140. This allows the two third rotating shafts 140 to drive the two third conveyor wheels 141 to rotate, and the two third conveyor wheels 141 and the two second conveyor wheels 138 cooperate to move the boxed food onto the third conveying mechanism 17.By installing at least two second lifting mechanisms 142 in at least two first support frames 131 respectively, and connecting at least two second lifting mechanisms 142 to a third support frame 135 simultaneously, the first support frame 131 supports the second lifting mechanisms 142, thereby enabling at least two second lifting mechanisms 142 to cooperate in driving the third support frame 135 to move up and down. This results in the second conveyor wheel 138 and the third conveyor wheel 141 being higher than the first conveyor wheel 134, and thus enabling the second conveyor wheel 138 and the third conveyor wheel 141 to fit against the bottom of the food container, so that the second conveyor wheel 138 and the third conveyor wheel 141 can cooperate in driving the container to move.

[0050] With the above structure, when the metal detector 11 does not detect any metal in the food, the boxed food removed from the first conveying mechanism 10 will move to multiple first conveying wheels 134. Then, the first rotating shaft 133 is rotated, causing the first rotating shaft 133 to drive the first conveying wheels 134 to rotate, thereby causing the multiple first conveying wheels 134 to cooperate in moving the boxed food to the second conveying mechanism 12, so that the second conveying mechanism 12 can move the boxed food to a predetermined position. At this time, the highest point of the second conveying wheel 138 and the third conveying wheel 141 is lower than the highest point of the first conveying wheel 134, so the second conveying wheel 138 and the third conveying wheel 141 will not come into contact with the box containing the food, thereby avoiding interference between the second conveying wheel 138 and the third conveying wheel 141 and the box, and thus avoiding damage to the box.

[0051] When the metal detector 11 detects metal in the food, it activates two second lifting mechanisms 142, causing multiple second lifting mechanisms 142 to drive the third support frame 135 upward, so that the highest point of the second conveyor wheel 138 and the third conveyor wheel 141 is higher than the highest point of the first conveyor wheel 134. Then, the first conveyor mechanism 10 moves the boxed food to the second conveyor wheel 138 and the third conveyor wheel 141. Subsequently, the second rotating shaft 137 and the third rotating shaft 140 are rotated simultaneously, causing the second rotating shaft 137 and the third rotating shaft 140 to drive the second conveyor wheel 138 and the third conveyor wheel 141 to rotate respectively, so that the second conveyor wheel 138 and the third conveyor wheel 141 cooperate to move the boxed food to the third conveyor mechanism 17, thereby classifying the food for subsequent processing.

[0052] In embodiments of the present invention, such as Figures 5 to 7As shown, the reversing transmission mechanism 13 further includes: a fourth rotating shaft 143, a first synchronous pulley 144, a second synchronous pulley 145, a first synchronous belt 146, a third synchronous pulley 147, a fourth synchronous pulley 148, a second synchronous belt 149, a fifth synchronous pulley 150, a third synchronous belt 151, and a notch 152; two fourth rotating shafts 143 are located inside the third support frame 135, and both ends of the two fourth rotating shafts 143 are rotatably connected to the third support frame 135; two first synchronous pulleys 144 are respectively fitted on the outside of the two fourth rotating shafts 143; two second synchronous pulleys 145 are respectively connected to the two second rotating shafts 137; the first synchronous belt 146 is simultaneously fitted on the outside of the first synchronous pulleys 144 and the second synchronous pulleys 145; two third synchronous pulleys... 147 is respectively fitted on the outside of the two fourth rotating shafts 143; the two fourth synchronous pulleys 148 are respectively connected to the two third rotating shafts 140; the second synchronous belt 149 is simultaneously fitted on the outside of the third synchronous pulleys 147 and the fourth synchronous pulleys 148; the two fifth synchronous pulleys 150 are respectively connected to the two fourth rotating shafts 143, and the two fifth synchronous pulleys 150 are located on the outside of the third support frame 135; the third synchronous belt 151 is simultaneously fitted on the outside of the two fifth synchronous pulleys 150; the notch 152 is provided on the side wall of the third support frame 135 near the first conveying mechanism 10, and the notch 152 is located below one of the first rotating shafts 133; wherein, the fourth rotating shaft 143 is located below the second rotating shaft 137 and the third rotating shaft 140.

[0053] By positioning the two fourth shafts 143 within the third support frame 135 and rotatably connecting both ends of the two fourth shafts 143 to the third support frame 135, the third support frame 135 supports the two fourth shafts 143, thereby enabling the two fourth shafts 143 to rotate within the third support frame 135. By mounting the two first synchronous pulleys 144 on the outer sides of the two fourth shafts 143 respectively, connecting the two second synchronous pulleys 145 to the two second shafts 137 respectively, and mounting the first synchronous belt 146 on the outer sides of both the first and second synchronous pulleys 144 and 145, when the fourth shafts 143 rotate, the fourth shafts 143 drive the second shafts 137 to rotate via the first synchronous pulleys 144, the second synchronous pulleys 145, and the first synchronous belt 146, thereby providing power for the rotation of the second shafts 137. By mounting two third synchronous pulleys 147 on the outside of two fourth rotating shafts 143 respectively, connecting two fourth synchronous pulleys 148 to two third rotating shafts 140 respectively, and mounting a second synchronous belt 149 on the outside of both third synchronous pulleys 147 and fourth synchronous pulleys 148, when the fourth rotating shaft 143 rotates, the fourth rotating shaft 143 drives the third rotating shaft 140 to rotate via the third synchronous pulleys 147, fourth synchronous pulleys 148, and second synchronous belt 149, thereby providing power for rotating the third rotating shaft 140. By connecting two fifth synchronous pulleys 150 to two fourth rotating shafts 143 respectively, and mounting a third synchronous belt 151 on the outside of both fifth synchronous pulleys 150, when one fourth rotating shaft 143 rotates, that fourth rotating shaft 143 drives the other fourth rotating shaft 143 to rotate via the two fifth synchronous pulleys 150 and the third synchronous belt 151, thereby achieving synchronous rotation of the two fourth rotating shafts 143. By setting the notch 152 on the side wall of the third support frame 135 near the first conveying mechanism 10 and placing the notch 152 below a first rotating shaft 133, interference between the third support frame 135 and the first rotating shaft 133 can be avoided when the third support frame 135 moves upward, thereby improving product quality.

[0054] By adopting the above structure, the second rotating shaft 137 and the third rotating shaft 140 are driven to rotate simultaneously by the fourth rotating shaft 143, so as to achieve synchronous rotation of the second rotating shaft 137 and the third rotating shaft 140, thereby achieving synchronous rotation of the second conveyor wheel 138 and the third conveyor wheel 141, thereby improving the effect of the second conveyor wheel 138 and the third conveyor wheel 141 in moving the boxed food. Furthermore, the fourth rotating shaft 143 drives the second rotating shaft 137 to rotate via the first synchronous pulley 144, the second synchronous pulley 145, and the first synchronous belt 146. The fourth rotating shaft 143 drives the third rotating shaft 140 to rotate via the third synchronous pulley 147, the fourth synchronous pulley 148, and the second synchronous belt 149. The fourth rotating shaft 143 is positioned below the second rotating shaft 137 and the third rotating shaft 140. This ensures that the second rotating shaft 137 and the third rotating shaft 140 rotate synchronously. Compared to directly connecting the second rotating shaft 137 and the third rotating shaft 140 together, the fourth rotating shaft 143 avoids interference with the first rotating shaft 133. This ensures that the third support frame 135 and the components within the third support frame 135 can move up and down. Consequently, the second conveyor wheel 138 and the third conveyor wheel 141 can both fit against the bottom of the food container and avoid contact with the food container, thus improving the user experience of the product.

[0055] In embodiments of the present invention, such as Figure 3 and Figure 6 As shown, the reversing transmission mechanism 13 further includes: a sixth synchronous pulley 153, a fourth synchronous belt 154, a first motor frame 155, a first motor body 156, a second motor frame 157, and a second motor body 158; the two sixth synchronous pulleys 153 are respectively connected to the two first rotating shafts 133, and the two sixth synchronous pulleys 153 are located outside the first support frame 131; the fourth synchronous belt 154 is simultaneously fitted on the outside of the two fourth synchronous pulleys 148; the first motor frame 155 is installed on the outside of the first support frame 131; the first motor body 156 is installed on the first motor frame 155, and the first motor body 156 is connected to the first rotating shaft 133; the second motor frame 157 is installed on the outside of the second support frame 132; the second motor body 158 is installed on the second motor frame 157, and the second motor body 158 is connected to the fourth rotating shaft 143.

[0056] By connecting two sixth synchronous pulleys 153 to two first rotating shafts 133 respectively, and simultaneously fitting a fourth synchronous belt 154 onto the outside of the two fourth synchronous pulleys 148, when one first rotating shaft 133 rotates, that first rotating shaft 133 drives the other first rotating shaft 133 to rotate via the two sixth synchronous pulleys 153 and the fourth synchronous belt 154, thereby achieving synchronous rotation of the two first rotating shafts 133; by mounting a first motor frame 155 on the outside of a first support frame 131, mounting a first motor body 156 on the first motor frame 155, and connecting the first motor body 156 to the first rotating shaft 133, The first motor frame 155 supports the first motor body 156, thereby enabling the first motor body 156 to drive the first rotating shaft 133 to rotate, thus providing power for rotating the first rotating shaft 133. The second motor frame 157 is installed on the outside of the second support frame 132, and the second motor body 158 is installed on the second motor frame 157 and connected to the fourth rotating shaft 143, so that the second motor frame 157 supports the second motor body 158, thereby enabling the second motor body 158 to drive the fourth rotating shaft 143 to rotate, thus providing power for rotating the fourth rotating shaft 143.

[0057] In embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the reversing conveyor mechanism 13 further includes: a first fixed frame 159, a first lead screw 160, a first guide bar, a first lifting block 161, a second lifting block 162, and a first baffle 163; the two first fixed frames 159 are respectively installed on both sides of the top of the second conveyor mechanism 12; the outer wall of the first lead screw 160 is provided with a first external thread, one end of the first lead screw 160 is rotatably connected to one side of the top of the second conveyor mechanism 12, and the other end of the first lead screw 160 is rotatably connected to one of the first fixed frames 159; one end of the first guide bar is connected to the second conveyor mechanism 12. The top is connected to the other side, and the other end of the first light bar is connected to another first fixing frame 159; the first lifting block 161 is provided with a first threaded hole, and the first threaded hole is provided with a first internal thread, and the first threaded hole of the first lifting block 161 is fitted on the outside of the first lead screw 160; the second lifting block 162 is fitted on the outside of the first light bar; the first baffle 163 is connected to both the first lifting block 161 and the second lifting block 162, and the first baffle 163 is located above the third support frame 135; wherein, the first external thread is adapted to the first internal thread.

[0058] By installing two first fixing brackets 159 on both sides of the top of the second conveying mechanism 12, rotatably connecting the two ends of the first lead screw 160 to one side of the top of the second conveying mechanism 12 and one first fixing bracket 159, and connecting the two ends of the first optical rod to the other side of the top of the second conveying mechanism 12 and another first fixing bracket 159, the second conveying mechanism 12 and the two first fixing brackets 159 cooperate to support the first lead screw 160 and the first optical rod. By fitting the first threaded hole of the first lifting block 161 onto the outside of the first lead screw 160, and fitting the second lifting block 162 onto the outside of the first optical rod, the first lead screw 160 and the first lifting block 161 are connected. The screw thread 160 enables the first lifting block 161 to move up and down, and the second lifting block 162 to move up and down along the first guide bar. By connecting the first baffle 163 to both the first lifting block 161 and the second lifting block 162 and positioning the first baffle 163 above the third support frame 135, the first lifting block 161 and the second lifting block 162 cooperate to support the first baffle 163. This allows the first lifting block 161 to move up and down when the first screw thread 160 drives the first lifting block 161 to move up and down, and the first lifting block 161 and the second lifting block 162 to drive the first baffle 163 to move up and down, thereby adjusting the height of the first baffle 163.

[0059] With the above structure, when the metal detector 11 does not detect metal in the food, the first lead screw 160 is rotated, causing the first lead screw 160 to move the first baffle 163 upward, thereby increasing the distance between the first baffle 163 and the third support frame 135. This prevents the first baffle 163 from blocking the boxed food, ensuring that the first conveyor wheel 134 can move the boxed food onto the second conveyor mechanism 12. When the metal detector 11 detects metal in the food, the first lead screw 160 is rotated in the opposite direction, causing the first lead screw 160 to move the first baffle 163 downward, thereby reducing the distance between the first baffle 163 and the third support frame 135. This prevents the first baffle 163 from blocking the boxed food, ensuring that the boxed food remains on the second conveyor wheel 138 and the third conveyor wheel 141. This allows the second conveyor wheel 138 and the third conveyor wheel 141 to work together to move the boxed food onto the third conveyor mechanism 17.

[0060] In embodiments of the present invention, such as Figure 5 and Figure 8As shown, the second lifting mechanism 142 includes: a first cylinder 1421, a first guide rod 1422, a first guide seat 1423, a first linear bearing 1424, and a first limiting plate 1425; the first cylinder 1421 is provided with a first output shaft, the first cylinder 1421 is installed in the first support frame 131, the first output shaft of the first cylinder 1421 passes through the bottom of the second support frame 132, and the first output shaft of the first cylinder 1421 is connected to the third support frame 135; one end of the two first guide rods 1422 is connected to the third support frame 135, and the other end of the two first guide rods 1422 is connected to the third support frame 135. The second support frame 132 and the third support frame 135 are passed through; two first guide seats 1423 are installed inside the first support frame 131, and the two first guide seats 1423 are respectively wrapped around the outside of the two first guide rods 1422; two first linear bearings 1424 are respectively installed inside the two first guide seats 1423, and the two first linear bearings 1424 are respectively fitted on the outside of the two first guide rods 1422; two first limiting plates 1425 are respectively connected to the other end of the two first guide rods 1422, and the two first limiting plates 1425 are respectively located below the two first guide seats 1423.

[0061] By installing the first cylinder 1421 inside the first support frame 131, allowing the first output shaft of the first cylinder 1421 to pass through the bottom of the second support frame 132, and connecting the first output shaft of the first cylinder 1421 to the third support frame 135, the first support frame 131 supports the first cylinder 1421. Simultaneously, without interfering with the second support frame 132, the first cylinder 1421 drives the first output shaft to move the third support frame 135 up and down, thereby adjusting the height of the third support frame 135. Furthermore, by connecting one end of each of the two first guide rods 1422 to the third support frame 135, and connecting the two first guide rods... The other end of the guide rod 1422 passes through the second support frame 132 and the third support frame 135 in sequence to realize that the two first guide rods 1422 and the third support frame 135 move up and down synchronously. By installing the first guide seat 1423 in the first support frame 131, installing the first linear bearing 1424 in the first guide seat 1423, and fitting the first linear bearing 1424 on the outside of the first guide rod 1422, the first guide seat 1423 guides the first guide rod 1422 through the first linear bearing 1424, thereby preventing the first guide rod 1422 and the third support frame 135 from deviating when moving up and down, so as to improve the stability of the third support frame 135 moving up and down. By connecting the first limiting plate 1425 to the other end of the first guide rod 1422 and positioning the first limiting plate 1425 below the first guide seat 1423, the first limiting plate 1425 and the first guide rod 1422 can move up and down synchronously. This ensures that when the other end of the first guide rod 1422 moves to the first guide seat 1423, the first limiting plate 1425 engages with the first guide seat 1423, thereby preventing the first guide rod 1422 from moving out of the first guide seat 1423 and improving the user experience of the product.

[0062] In embodiments of the present invention, such as Figure 1 and Figure 2As shown, the food testing device also includes: a second fixed frame 29, a third motor body 30, a second lead screw 31, a second moving plate 32, a second optical bar 33, a connecting rod 34, and a second baffle 35; the second fixed frame 29 is installed on one end of the third conveying mechanism 17 away from the reversing conveying mechanism 13; the third motor body 30 is installed on the second fixed frame 29; a second external thread is provided on the outer wall of the second lead screw 31, one end of the second lead screw 31 is rotatably connected to the third conveying mechanism 17, and the other end of the second lead screw 31 is connected to the third motor body 30; a second threaded hole is provided in the second moving plate 32. The second threaded hole is provided with a second internal thread. The second moving plate 32 is located inside the second fixed frame 29, and the second lead screw 31 passes through the second threaded hole of the second moving plate 32. One end of the second optical rod 33 is connected to the second fixed frame 29, and the other end of the second optical rod 33 is connected to the third conveying mechanism 17. The second optical rod 33 passes through the second moving plate 32. One end of the two connecting rods 34 is connected to the second moving plate 32. The second baffle 35 is connected to the other end of the two connecting rods 34, and the second baffle 35 is located above the third conveying mechanism 17. The second external thread is adapted to the second internal thread.

[0063] By mounting the second fixed frame 29 on one end of the third transmission mechanism 17 away from the reversing transmission mechanism 13, and mounting the third motor body 30 on the second fixed frame 29, the third transmission mechanism 17 supports the third motor body 30 through the second fixed frame 29, thereby improving the stability of the third motor body 30. By rotatably connecting one end of the second lead screw 31 to the third transmission mechanism 17 and connecting the other end of the second lead screw 31 to the third motor body 30, the third transmission mechanism 17 and the third motor body 30 cooperate to support the second lead screw 31, thereby enabling the third motor body 30 to drive the second lead screw 31 to rotate within the second fixed frame 29. By positioning the second movable plate 32 within the second fixed frame 29 and allowing the second lead screw 31 to pass through the second threaded hole of the second movable plate 32, a threaded connection is achieved between the second lead screw 31 and the second movable plate 32. This allows the second lead screw 31 to rotate, causing the second movable plate 32 to move within the second fixed frame 29. By connecting one end of the second optical rod 33 to the second fixed frame 29 and the other end of the second optical rod 33 to the third transmission mechanism 17, and allowing the second optical rod 33 to pass through the second movable plate 32, the third transmission mechanism 17 and the second fixed frame 29 cooperate to support the second optical rod 33. This enables the second movable plate 32 to move along the second optical rod 33, thereby improving the stability of the movement of the second movable plate 32. By connecting one end of the two connecting rods 34 to the second moving plate 32 and connecting the second baffle 35 to the other end of the two connecting rods 34, and positioning the second baffle 35 above the third conveying mechanism 17, when the second moving plate 32 moves, the second moving plate 32 drives the second baffle 35 to move through the two connecting rods 34. This allows the second baffle 35 to block and position the boxed food conveyed by the third conveying mechanism 17, ensuring that the boxed food remains in the mounting rack 19, thus facilitating subsequent food inspection.

Inside 21; the outer wall of the third lead screw 203 is provided with a third external thread, the two ends of the third lead screw 203 are respectively rotatably connected to the two first mounting plates 202, and the third lead screw 203 passes through the third thread hole; the two ends of the third optical rod 204 are respectively connected to the two first mounting plates 202, and the third optical rod 204 passes through the first moving plate 21; the fourth motor body 205 is installed on the top of the mounting bracket 19, and the fourth motor body 205 is connected to the third lead screw 203; wherein, the third external thread is adapted to the third internal thread.

By mounting two first mounting plates 202 on the top of the mounting bracket 19, placing the two first mounting plates 202 on either side of the clearance groove 201, and rotatably connecting the two ends of the third lead screw 203 to the two first mounting plates 202 respectively, the two first mounting plates 202 can move within the clearance groove 201. The first mounting plate 202 and the second mounting plate 202 work together to support the third lead screw 203, so that the third lead screw 203 can rotate between the two first mounting plates 202.

This allows the mounting bracket 19 and the third transmission mechanism 17 to cooperate in supporting the fifth motor body 261, thereby enabling the fifth motor body 261 to drive the fourth lead screw 262 to rotate. By setting the fourth threaded hole inside the lifting plate 27 and allowing the fourth lead screw 262 to pass through the fourth threaded hole, a threaded connection is achieved between the fourth lead screw 262 and the lifting plate 27. When the fifth motor body 261 drives the fourth lead screw 262 to rotate, the fourth lead screw 262 can drive the lifting plate 27 to move up and down, thereby adjusting the height of the lifting plate 27 and the third detector 28, so that the third detector 28 can detect different positions of the packaged food. By connecting one end of the fourth light bar to the top of the mounting frame 19 and the other end of the fourth light bar to the top of the third conveying mechanism 17, and allowing the fourth light bar to pass through the lifting plate 27, the mounting frame 19 and the third conveying mechanism 17 cooperate to support the fourth light bar, thereby enabling the lifting plate 27 to move up and down along the fourth light bar, thus improving the stability of the movement of the lifting plate 27.

By setting the fifth threaded hole in the adjusting plate 24 and allowing the fifth lead screw to pass through the fifth threaded hole, the fifth lead screw is threadedly connected to the adjusting plate 24, thereby enabling the fifth lead screw to rotate and drive the adjusting plate 24 and the third detector 28 to move, thereby adjusting the position of the third detector 28 and enabling the third detector 28 to detect different positions of the packaged food. By connecting the two ends of the fifth optical bar to the two second mounting plates respectively and allowing the fifth optical bar to pass through the adjusting plate 24, the two second mounting plates cooperate to support the fifth optical bar, thereby enabling the adjusting plate 24 to move along the fifth optical bar, thereby improving the stability of the movement of the adjusting plate 24.
