Description

Technical Field

[0001] This utility model relates to the field of quick-frozen vegetable detection technology, specifically a metal detector for detecting foreign objects in quick-frozen vegetables. Background Technology

[0002] When vegetables are frozen, their core temperature must drop from -1°C to -5°C and then to below -15°C within 30 minutes. Only frozen vegetables that achieve or exceed this speed can be called quick-frozen vegetables. During quick-freezing, because the dehydration time is short, water can quickly pass through the maximum crystallization zone between 0°C and -5°C, causing tiny ice crystals to form simultaneously inside and between cells without damaging the cell walls. After thawing, the vegetables have good rehydration properties, largely retaining their original color, aroma, flavor, shape, and nutritional components.

[0003] As a common food item, frozen vegetables may be contaminated with metal foreign objects during processing and packaging, affecting food safety and consumer health. These metal foreign objects may originate from wear and tear on production equipment, accidents during processing, or pollution from the external environment. To ensure the quality and safety of frozen vegetables, effective measures must be taken to detect foreign objects, especially metal foreign objects. Therefore, a metal detection foreign object detection machine specifically designed for frozen vegetables is needed.

[0004] However, most existing metal detection foreign object detection machines for quick-frozen vegetables cannot effectively and promptly separate quick-frozen vegetables that have detected metal foreign objects during use, and cannot achieve automated sorting. This not only increases the workload of subsequent manual sorting, but also affects the overall production efficiency and detection effect. Therefore, a metal detection foreign object detection machine for quick-frozen vegetables is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem that most existing metal detection foreign object detectors for quick-frozen vegetables cannot effectively and promptly separate quick-frozen vegetables that have detected metal foreign objects, and cannot achieve automated sorting, which not only increases the workload of subsequent manual sorting, but also affects the overall production efficiency and detection effect, this utility model proposes a metal detection foreign object detector for quick-frozen vegetables.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a metal detector for detecting foreign objects in quick-frozen vegetables, including a detection platform, with support blocks fixedly connected to the four corners of the bottom of the detection platform.

[0007] A U-shaped plate is fixedly connected to the top of the detection platform. A metal detector body is fixedly installed on the upper surface inside the U-shaped plate. A groove is opened on the top of the detection platform, and a detection plate is set inside the groove. The detection plate corresponds to the metal detector body inside the U-shaped plate. A controller is fixedly installed on the upper left side of the detection platform.

[0008] Preferably, an inner groove is formed on the lower surface of the groove, and through-type conveying ports are formed on both the left and right sides of the inner groove. A conveyor belt is fixedly installed on the lower surface of the conveying port, and the conveyor belt is fixedly installed to the testing table through a support plate.

[0009] Preferably, mounting holes are provided on both the front and rear surfaces of the groove. A through hole is provided on the front surface of the front mounting hole. A rotating rod is rotatably connected to the front mounting hole via a bearing. The front end of the rotating rod extends into the through hole. A connecting rod is rotatably connected to the rear mounting hole via a bearing. The opposite ends of the rotating rod and the connecting rod are fixedly connected to the front and rear surfaces of the detection plate, respectively.

[0010] Preferably, a motor is fixedly installed above the center of the front surface of the detection platform, the output end of the motor extends into the through hole, the output end of the motor is fixedly connected to the front end of the rotating rod, and the metal detector body and the motor are both electrically connected to the controller.

[0011] Preferably, the top of the detection plate has a through-hole mounting groove, and the front and rear surfaces of the mounting groove have limit grooves. Limit blocks are slidably connected inside the limit grooves, and an extension plate is fixedly connected between the two limit blocks. The extension plate is slidably installed with the detection plate.

[0012] Preferably, the left and right sides of the detection plate and the left and right sides of the extension plate are all arc-shaped, the upper part of the left and right sides inside the inner groove is also arc-shaped, and the connection between the left and right sides inside the inner groove and the inside of the groove is chamfered.

[0013] Preferably, an electric lifting rod is fixedly installed at the center of the top of the U-shaped plate, the output end of the electric lifting rod passes through the U-shaped plate, and the output end of the electric lifting rod is fixedly connected to the metal detector body.

[0014] The advantages of this utility model are:

[0015] 1. When a metal foreign object is detected, the controller can rotate the detection plate to the left for sorting. When no metal foreign object is detected, the controller can rotate the detection plate to the right for sorting. This allows the detection machine to separate frozen vegetables that have detected metal foreign objects in a timely and effective manner, and it can achieve automated sorting. This not only reduces the workload of subsequent manual sorting, but also increases the overall production efficiency and detection effect. As a result, the detection machine is convenient to use and has a good effect.

[0016] 2. This utility model uses an electric lifting rod to move the metal detector body up and down to adjust its position when powered on.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4 As shown, a metal detector for detecting foreign objects in quick-frozen vegetables includes a detection platform 1, with support blocks fixedly connected to the four corners of the bottom of the detection platform 1.

[0027] A U-shaped plate 3 is fixedly connected to the top of the detection platform 1. A metal detector body 4 is fixedly installed on the upper inner surface of the U-shaped plate 3. A groove 2 is provided on the top of the detection platform 1, and a detection plate 5 is arranged inside the groove 2. The detection plate 5 corresponds to the metal detector body 4 inside the U-shaped plate 3. A controller 10 is fixedly installed on the upper left side of the detection platform 1. During operation, the bottom of the support block is first placed against a flat ground to stabilize the detection machine. After the detection machine is stabilized, the frozen vegetables to be tested are placed on the detection plate 5, and then detected through the U-shaped plate 3. The metal detector body 4 of the unit detects metal foreign objects. When a metal foreign object is detected, the controller 10 controls the detection plate 5 to rotate to the left for sorting. When no metal foreign object is detected, the controller 10 controls the detection plate 5 to rotate to the right for sorting. This allows the detection machine to separate frozen vegetables that have detected metal foreign objects in a timely and effective manner, and it can realize automated sorting. This not only reduces the workload of subsequent manual sorting, but also increases the overall production efficiency and detection effect. As a result, the detection machine is easy to use and has a good effect.

[0028] The lower surface of the groove 2 is provided with an inner groove 11. Both the left and right sides of the inner groove 11 are provided with through conveying ports 9. A conveyor belt 8 is fixedly installed on the lower surface of the inner groove 9. The conveyor belt 8 is fixedly installed to the detection table 1 through a support plate. During operation, the inner groove 11 facilitates the rotation and sorting of the detection plate 5. After the detection plate 5 rotates and sorts, it falls onto the conveyor belt 8 and is conveyed out by the conveyor belt 8, which facilitates the sorted frozen vegetables to be conveyed out for collection and subsequent processing.

[0029] Mounting holes are provided on both the front and rear surfaces of the groove 2. A through hole is provided on the front surface of the mounting hole. A rotating rod 15 is rotatably connected to the front mounting hole via a bearing 1. The front end of the rotating rod 15 extends into the through hole. A connecting rod is rotatably connected to the rear mounting hole via a bearing 2. The ends of the rotating rod 15 and the connecting rod are respectively fixedly connected to the front and rear surfaces of the detection plate 5. During operation, the rotatably connected connecting rod and rotating rod 15 facilitate the rotation of the detection plate 5 inside the detection table 1 for sorting.

[0030] A motor 7 is fixedly installed above the center of the front surface of the detection platform 1. The output end of the motor 7 extends into the through hole and is fixedly connected to the front end of the rotating rod 15. The metal detector body 4 and the motor 7 are both electrically connected to the controller 10. During operation, the motor 7 is powered on to drive the rotating rod 15 to rotate, and the rotation of the rotating rod 15 drives the detection plate 5 to rotate under the rotation limit of the connecting rod, so that the detection plate 5 can rotate to sort the detected frozen vegetables. After the metal detector body 4 detects a metal foreign object, it will transmit a signal to the controller 10. The controller 10, controlled by a PLC, will execute relevant actions based on the signal from the metal detector body 4. After receiving the metal detection signal, the controller 10 controls the rotation direction of the detection plate 5 through the motor 7. If there is no metal foreign object, the detection plate 5 continues to rotate to the right. If a metal foreign object is detected, the control plate turns to the left. At the same time, the controller 10 is set with a timed reset module, so after the detection plate 5 completes one sorting, the system will wait for a certain period of time and then automatically reset, so as to facilitate the continued detection and sorting.

[0031] The top of the detection plate 5 has a through-hole mounting groove 12. Limiting grooves 13 are formed on both the front and rear surfaces of the mounting groove 12. Limiting blocks 14 are slidably connected inside the limiting grooves 13. An extension plate 6 is fixedly connected between the two limiting blocks 14. The extension plate 6 is slidably installed with the detection plate 5. During operation, the movement of the extension plate 6 is limited by the sliding of the limiting blocks 14 within the limiting grooves 13. When the limiting blocks 14 slide to the inner sidewall of the limiting groove 13, the movement of the extension plate 6 stops. The extension plate 6 also stops extending after the detection plate 5 stops rotating. During the sorting process of the detection plate 5, the extension plate 6 tilts and moves, causing the frozen vegetables that have been inspected at the top to fall. These vegetables then fall onto the conveyor belt 8 and are conveyed out for subsequent collection and processing, thus facilitating the sorting and collection of the inspected frozen vegetables.

[0032] The left and right sides of the detection plate 5 and the left and right sides of the extension plate 6 are all set in an arc shape. The upper part of the left and right sides inside the inner groove 11 is also set in an arc shape. The left and right sides inside the inner groove 11 and the connection with the inside of the groove 2 are provided with chamfers. During operation, it is convenient for the extension plate 6 to move downward by gravity automatically when the detection plate 5 rotates, and it is also convenient for the extension plate 6 to be squeezed and slid back to its original position when the detection plate 5 is reset.

[0033] Example 2

[0034] Please see Figure 5 As shown in the comparative embodiment one, as another implementation of this utility model, an electric lifting rod 16 is fixedly installed at the top center of the U-shaped plate 3. The output end of the electric lifting rod 16 passes through the U-shaped plate 3 and is fixedly connected to the metal detector body 4. During operation, the electric lifting rod 16 is powered on to drive the metal detector body 4 to move up and down to adjust its position. This allows the metal detector body 4 to adjust its position according to the size of the frozen vegetables during detection, and avoids the detection results being affected by distance. As a result, this detection machine can meet more usage needs and is convenient to use.
