Abstract
Description
Technical Field
[0001] This utility model relates to the field of food testing technology, and in particular to a testing device for bagged vegetables. Background Technology
[0002] In the vegetable production and processing sector, packaged vegetables are widely welcomed by the market due to their convenience. However, ensuring the quality and safety of packaged vegetables is of paramount importance. Metal impurities (such as iron wire, blade fragments, and machine parts) may be mixed into packaged vegetables during planting, harvesting, processing, or packaging. These impurities cannot be effectively detected by manual testing, which can lead to harm to consumers after the vegetables are ingested.
[0003] Currently, there are many metal detectors available on the market for food testing, such as the commonly seen Anritsu brand metal detectors, which can be used to detect metal impurities in packaged vegetables. (See attached instruction manual.) Figure 1 The device consists of a detector body 1 and a support bracket 2. A detection opening 3 runs horizontally through the detector body, housing an existing metal detection device. A conveyor belt 4 is installed at the bottom of the opening to transport the bagged vegetables to be detected. In actual operation, the bagged vegetables are manually positioned at the center of the conveyor belt 4 and transported into the detection opening 3 for detection. After detection, they are transported away by the conveyor belt 4. During this process, if the bagged vegetables do not contain metal impurities, the display screen on the outside of the detector body shows green (pass); if they contain metal impurities, it shows red (fail). The staff then removes the bagged vegetables that fail to pass through the upper part of the conveyor belt.
[0004] Based on this, the aforementioned metal detectors still have the following technical defects when in use. For example, the packaging bags of different vegetable varieties are of different sizes, and it is difficult to ensure that they are completely centered on the conveyor belt during the detection process. This makes it difficult to fully and accurately align them with the bottom of the metal detector probe during detection. In addition, the existing metal detectors can only determine whether the bagged vegetables contain metal impurities and then display it on the screen, but they cannot remove the bagged vegetables containing metal impurities from the conveyor belt. This still requires manual removal by staff, which greatly reduces the overall detection efficiency. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a detection device for bagged vegetables, including a bracket for supporting and mounting the detector body, a detection opening that is laterally provided through the outer side of the detector body, a metal detection device being provided at the upper end of the detection opening, and a conveyor belt for transporting the bagged vegetables into the detection opening being installed at the upper end of the bracket, and further including: The guide assembly, which has a detection opening, consists of two sets of symmetrical limiting plates. A guide frame is provided on the outer end of the limiting plate. Multiple sets of guide rollers are rotatably arranged inside the guide frame. After the bagged vegetables at the top of the conveyor belt are guided by the guide rollers on the inner wall of the guide frame, they are limited and centered by the two sets of limiting plates, which facilitates accurate docking with the bottom of the metal detection equipment. The feeding assembly includes an electric push rod fixedly installed on the outer wall of the inner end of a set of limiting plates. The power end of the electric push rod moves through the set of limiting plates and is fixedly connected to a push plate. The outer wall of another set of limiting plates is provided with a discharge port, which is connected to the push plate. This allows the push plate to push the bagged vegetables containing metal impurities from the upper end of the conveyor belt out of the discharge port under the drive of the electric push rod.
[0006] As a further improvement to the above solution, the outer end of the limiting plate is rotatably connected to a connecting shaft, and the connecting shaft is fixedly connected to the guide frame. The outer end of the limiting plate is also provided with an angle adjustment component for adjusting the installation angle of the guide frame.
[0007] As a further improvement to the above solution, the angle adjustment component includes: The rotating handle is fixedly connected to the upper end of the connecting shaft for easy rotation of the connecting shaft. A limit pin is inserted through the upper end of the rotating handle, and a fixing block is fixedly connected to the upper end of the limit pin, which can be inserted and removed. A limiting plate is fixedly connected to the upper part of the outer side of the limiting plate. Multiple sets of limiting holes are evenly arranged on the upper end of the limiting plate. The limiting holes and the limiting pins are inserted and matched to facilitate the fixing of the guide frame angle. A label is provided on the upper part of the limiting plate outside the limiting holes. The label is written with the type of bagged vegetables and is used to mark the limiting holes.
[0008] As a further improvement to the above solution, the fixing block is connected to the upper end of the rotating handle by a spring, the spring is sleeved on the outside of the limiting pin, and the spring is in a contracted state by default.
[0009] As a further improvement to the above solution, a mounting plate is fixedly connected to the outside of the detector body. The mounting plate is used to movably mount the limiting plate, and a distance adjustment component is provided between the mounting plate and the limiting plate to adjust the distance between the relative limiting plates.
[0010] As a further improvement to the above solution, the distance adjustment component includes: A fixing sleeve is fixedly connected to the inner wall of the mounting plate at its outer end, and a limit block is fixedly connected to the inner wall of the fixing sleeve near the opening at its inner end. The inner end of the threaded sleeve is fixedly connected to the outer wall of the limiting plate, and the outer end of the threaded sleeve is movably inserted into the opening on the inner side of the fixed sleeve and extends into its inner cavity. The outer wall of the threaded sleeve is provided with a limiting groove, which is slidably engaged with the outer side of the limiting block. The rotating sleeve is rotatably connected to the inner end of the fixed sleeve via a bearing, and the rotating sleeve is threaded onto the outer side of the threaded sleeve. By adjusting the rotation of the rotating sleeve and driving the threaded sleeve to extend and retract within the fixed sleeve, the distance between the relative limiting plates can be adjusted.
[0011] As a further improvement to the above solution, the electric push rod is fixedly connected to the outside of the limiting plate by a mounting bracket, and the electric push rod is electrically connected to the detector body by a PLC controller.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a limiting plate in conjunction with an outer guide frame and guide roller, can guide bagged vegetables that are manually placed on the conveyor belt and connect them to the center of the detection opening, which facilitates accurate detection and also makes it easy for them to be accurately conveyed out from the center of the conveyor belt for collection. Based on this, the present invention can also adjust the opening and closing angle of the guide frame by using the angle adjustment component according to the packaging bags of different sizes of bagged vegetables, and adapt the distance between the limiting plates by using the distance adjustment component to meet the actual use. (2) The present invention provides a pusher component at the position of the conveyor belt near the discharge end, which automatically removes the bagged vegetables containing metal impurities from the conveyor belt and collects them separately without manual assistance, thereby improving the overall detection efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Please combine Figure 2-6A detection device for bagged vegetables includes a bracket 2 supporting a detector body 1. A detection opening 3 is laterally provided through the outer side of the detector body 1. A metal detection device is installed at the upper end of the detection opening 3. A conveyor belt 4 is installed at the upper end of the bracket 2 to transport the bagged vegetables into the detection opening 3. The device also includes a guide assembly, located within the detection opening 3, composed of two sets of symmetrical limiting plates 5. A guide frame 6 is provided at the outer end of each limiting plate 5. Multiple sets of guide rollers 7 are rotatably arranged inside the guide frame 6. The bagged vegetables at the upper end of the conveyor belt 4 are guided by the guide rollers 7 on the inner wall of the guide frame 6 and then positioned centrally by the two sets of limiting plates 5, facilitating accurate detection. The device is attached to the bottom of the metal detection equipment. The pushing assembly includes an electric push rod 13 fixedly installed on the outer wall of the inner end of a set of limiting plates 5. The power end of the electric push rod 13 moves through the set of limiting plates 5 and is fixedly connected to a push plate 14. The outer wall of another set of limiting plates 5 is provided with a discharge port 15, which is connected to the push plate 14. This allows the push plate 14 to push the bagged vegetables containing metal impurities from the upper end of the conveyor belt 4 out of the discharge port 15 under the drive of the electric push rod 13. The electric push rod 13 is fixedly connected to the outer side of the limiting plate 5 through the mounting bracket 1301, and the electric push rod 13 is electrically connected to the detector body 1 through the PLC controller.
[0020] Based on this, the embodiment of this utility model is as follows: the staff places the bagged vegetables in the conveyor belt 4 and transports them to the detection opening 3. During this process, the bagged vegetables are guided by the inclined guide frame 6 and the guide roller 7 rotating on the inner wall, and then gradually move towards the center until they are guided between the two sets of limiting plates 5. The relative limiting plates 5 accurately transport them to the center position of the detection opening 3. The metal detection device set at the upper end of the detection opening 3 is used to detect metal impurities inside the bagged vegetables. If the detection result is that there are no metal impurities, the bagged vegetables are transported to the end of the conveyor belt 4 for collection. If metal impurities are detected, the detector body 1 drives the electric push rod 13 through the PLC controller to drive the push plate 14 at the power end to move, pushing the bag containing metal impurities out of the upper end of the conveyor belt 4 and through the discharge port 15 to the designated collection position for unified collection, which is convenient for subsequent processing.
[0021] The reference manual is attached. Figure 5The outer end of the limiting plate 5 is rotatably connected to a connecting shaft 8, which is fixedly connected to the guide frame 6. The outer end of the limiting plate 5 is also provided with an angle adjustment assembly for adjusting the installation angle of the guide frame 6. The angle adjustment assembly includes a rotating handle 9, which is fixedly connected to the upper end of the connecting shaft 8 to facilitate rotation of the connecting shaft 8. A limiting pin 901 is movably inserted through the upper end of the rotating handle 9, and a fixing block 902 is fixedly connected to the upper end of the limiting pin 901, allowing the limiting pin 901 to be inserted and removed. A limiting plate 10 is fixedly connected to the limiting plate 5. Above the outer end, multiple sets of limiting holes 1001 are evenly arranged on the upper end of the limiting plate 10. The limiting holes 1001 and the limiting pins 901 are inserted and matched to facilitate the angle fixation of the guide frame 6. A label 1002 is provided on the upper end of the limiting plate 5 outside the limiting holes 1001. The label 1002 is written with the type of bagged vegetables and is used to mark the limiting holes 1001. The fixing block 902 is connected to the upper end of the rotating handle 9 by a spring. The spring is sleeved on the outside of the limiting pins 901 and is in a contracted state by default.
[0022] Based on this, considering that different varieties of bagged vegetables vary in size, in order to better guide them between the two sets of limiting plates 5, it is necessary to adjust the tilt angle of the guide frame 6 so that the "opening angle" of the two sets of opposing guide frames 6 is slightly larger than the size of the bagged vegetables. The worker pulls the limiting pin 901 and stretches the spring by fixing block 902, so that the limiting pin 901 disengages from the limiting hole 1001. At this time, the angle of the guide frame 6 can be adjusted by rotating the connecting shaft 8. During the rotation, the worker can observe the label 1002 on the outside of the limiting hole 1001 corresponding to the limiting pin 901, select the label 1002 corresponding to the variety of bagged vegetables, and then release the fixing block 902. Under the spring's extension and contraction, the positioning pin 901 is driven to engage again in the corresponding positioning hole 1001, thereby fixing the angle of the adjusted guide frame 6. This adjustment method is simple and convenient. With the label 1002, the corresponding angle positioning position can be quickly found. It is very portable and saves the worker's time.
[0023] The reference manual is attached. Figure 4 , 6An installation plate 11 is fixedly connected to the outside of the detector body 1. The installation plate 11 is used to movably install the limiting plate 5. A distance adjustment component 12 is provided between the installation plate 11 and the limiting plate 5 to adjust the distance between them. The distance adjustment assembly 12 includes: a fixed sleeve 1201, the outer end of which is fixedly connected to the inner wall of the mounting plate 11, and a limiting block 1205 is fixedly connected to the inner wall of the fixed sleeve 1201 near the opening of the inner end; a threaded sleeve 1202, the inner end of which is fixedly connected to the outer wall of the limiting plate 5, and the outer end of the threaded sleeve 1202 is movably inserted into the opening of the inner side of the fixed sleeve 1201 and extends into its inner cavity, and a limiting groove 1204 is provided on the outer wall of the threaded sleeve 1202, the limiting groove 1204 being slidably engaged with the outer side of the limiting block 1205; and a rotating sleeve 1203, which is rotatably connected to the inner end of the fixed sleeve 1201 through a bearing, and the rotating sleeve 1203 is threadedly sleeved on the outer side of the threaded sleeve 1202. By adjusting the rotation of the rotating sleeve 1203 and the threaded drive of the threaded sleeve 1202 to extend and retract within the fixed sleeve 1201, the distance between the fixed sleeve 1201 and the limiting plate 5 can be adjusted.
[0024] Based on this, considering that different varieties of bagged vegetables vary in size, in order to better transport them to the bottom of the metal detection device at the upper end of the detection opening, it is necessary to adjust the distance between the two sets of limiting plates 5. By adjusting the rotation of the rotating sleeve 1203, the rotating sleeve 1203 drives the threaded sleeve 1202. Since the limiting groove 1204 on the outer side of the threaded sleeve 1202 is engaged with the limiting block 1205 on the inner wall of the fixed sleeve 1201, the threaded sleeve 1202 moves in and out of the fixed sleeve 1201 under the drive of the rotating sleeve 1203, thereby adjusting the position of the limiting plates 5, that is, adjusting the distance between the relatively set limiting plates 5, so as to match the size of the bagged vegetables for precise guidance and meet the needs of detection and production.
[0025] It should also be added that a scale or label 1202 can be set in the limiting groove 1204, so that staff can quickly adjust the distance between the relative limiting plates 5 according to the variety of bagged vegetables, saving time and effort.
[0026] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
[0027] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
