Description

Technical Field

[0001] The utility model relates to the technical field of weighing and sorting, in particular to a weight grading scale with a metal detection function. Background Art

[0002] A weight grading scale is a device specially used for automatic classification and grading of items according to their weight. It is widely used in many industries such as food, chemical industry, logistics, etc., especially in scenarios where precise weight control of products is required. Weight grading scales are particularly important. For example, the patent number is: ZL202020489886.1, and the patent name is: A utility model patent for an intelligent weight grading scale for large material boxes, which achieves an intelligent weight grading effect. The weight grading scale is generally provided with a holding table for holding and transporting items to be graded, such as the patent number: ZL201821020474.2, and the patent number is: A utility model patent for a holding table of a weight sorting machine.

[0003] However, in actual use, not only weight grading is required, but also sorting of qualified products is required. For example, oysters are not only sorted by weight, but also dead oysters need to be removed. The existing weight grading scale can only achieve weight sorting, and cannot remove dead oysters.

[0004] During the oyster farming process, oysters sometimes die due to environmental factors, diseases or other unpredictable reasons. These dead oysters gradually lose their original meat in the ocean and become empty shells. Due to long-term immersion and tidal effects, the shells are often filled with mud and a small amount of metal impurities, forming the so-called "mud shells". These "mud shell" oysters are often no different from normal oysters in appearance. Whether it is color, shape or weight, it is difficult to distinguish them with the naked eye. However, once consumers buy these "mud shell" oysters, they will find that there is no meat in them, only full of mud when they eat them. This will undoubtedly seriously affect their purchasing experience and even have a negative impact on the quality and reputation of oysters.

[0005] Currently, testing is done manually, which not only requires a lot of manpower and time, but is also extremely inefficient, and it is even more difficult to ensure that every oyster is accurately tested. Summary of the invention

[0006] To solve the above problems, the present application provides a weight grading scale with a metal detection function, which is provided with a frame, on which a controller, a driver and a conveying chain are provided, on which a holding platform is provided, on which a metal coil is provided, and on which metal contact points are provided at the front and rear ends of the holding platform, the metal coil is electrically connected to the metal contact points, and on the frame a metal signal plate cooperating with the metal contact points is provided, and the metal signal plate is electrically connected to the controller.

[0007] In one embodiment, the holding table includes a fixed seat and a swing frame, the swing frame is movably mounted on the fixed seat via a swing shaft, a material box is provided on the swing frame, and active parts are provided on both sides of the swing frame, and the metal contact point is provided on the active part.

[0008] In one embodiment, the two metal signal plates are horizontally arranged and are in the same horizontal plane, and the metal signal plates are located below the metal contact points.

[0009] In one embodiment, a plurality of rejectors are arranged side by side on the frame.

[0010] In one embodiment, an electronic scale is provided on the frame.

[0011] In one embodiment, the frame is further provided with lifting feet.

[0012] The beneficial effects of the utility model are:

[0013] The present application discloses a weight grading scale with a metal detection function, which forms a closed path by arranging a metal coil, a metal contact point, a metal signal plate, and a controller to form a magnetic field detection device for detecting "mud shell" oysters. That is, when the "mud shell" oysters fall from the feeding device to the storage table, they will pass through the metal coil, generate magnetic field fluctuations and be converted into electrical signals, which are transmitted to the controller through the metal signal plate. After the controller receives the electrical signal from the metal signal plate, the controller analyzes and processes the received electrical signal according to a preset logic algorithm. When the controller determines that it is a "mud shell" oyster, the controller controls the storage table to remove the "mud shell" oysters, thereby improving the efficiency and accuracy of sorting.

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] like Figure 1-4 As shown, a weight grading scale with a metal detection function is provided with a frame 1, on which a controller 2, a driver 3 and a conveying chain 4 are provided, on which a holding platform 5 is provided, on which a metal coil 51 is provided, and on which metal contact points 52 are provided at the front and rear ends of the holding platform 5, the metal coil 51 is electrically connected to the metal contact points 52, and on the frame 1 a metal signal plate 53 cooperating with the metal contact points 52 is provided, and the metal signal plate 53 is electrically connected to the controller 2.

[0031] Specifically, the driver 3 can drive the conveyor chain 4 to operate, thereby driving the storage table 5 to move. When the metal contact points 51 at both ends of the storage table 5 contact the metal signal plate 53 on the frame 1, the metal coil 51, the metal contact point 52, the metal signal plate 53, and the controller 2 form a closed path to form a magnetic field detection device for detecting "mud shell" oysters. That is, when the "mud shell" oysters fall from the feeding device to the storage table 5, they will pass through the metal coil 51, generate magnetic field fluctuations and be converted into electrical signals, and the electrical signals are transmitted to the controller 2 through the metal signal plate 53. After the controller 2 receives the electrical signal from the metal signal plate 53, the controller 2 analyzes and processes the received electrical signal according to the preset logic algorithm. When the controller 2 determines that it is a "mud shell" oyster, the controller 2 controls the storage table 5 to remove the "mud shell" oysters. By setting a metal coil 51, a metal contact point 52, a metal signal plate 53, and a controller 2 to form a magnetic field detection device for detecting "mud shell" oysters, "mud shell" oysters can be quickly identified and removed, thereby improving the efficiency and accuracy of sorting, achieving the removal of single unqualified oysters, and improving the utilization efficiency of existing equipment.

[0032] like Figure 4-6 As shown, the storage table 5 includes a fixed seat 54 and a swing frame 55. The swing frame 55 is movably mounted on the fixed seat 54 through a swing shaft 56. A material box 57 is arranged on the swing frame 55. Active parts 58 are arranged on both sides of the swing frame 55. The metal contact point 52 is arranged on the active part 58.

[0033] Specifically, the fixed seat 54 is installed on the conveyor chain 4, the material box 57 is fixedly installed on the swing frame 55, the swing frame 55 can rotate around the swing shaft 56, the action member 58 acts on the unloading platform or the return platform to generate external force to make the swing frame 1 tilted or vertical, and the metal contact point 52 is set on the action member 58, so that the metal contact point 52 contacts the metal signal plate 53 during the movement.

[0034] like Figure 3 As shown, the two metal signal plates 53 are horizontally arranged and are in the same horizontal plane, and the metal signal plates 53 are located below the metal contact points 52 .

[0035] Specifically, the two metal signal plates 53 are arranged horizontally, and the metal signal plates 53 are located below the metal contact points 52, which can support the action members 58 on both sides of the pendulum 55 to keep the material box 57 in a horizontal state, and can also ensure that the metal contact points 52 maintain accurate and reliable contact with the metal signal plates 53 during the movement. The two metal contact points 52 can maintain a continuous loop state on the metal signal plates 53, ensuring that signals can be continuously and stably generated when objects such as oysters pass by.

[0036] like Figure 2As shown, a plurality of rejectors 6 are arranged side by side on the frame 1 .

[0037] Specifically, the controller 2 sends a command to the rejector 6 according to the received signal. When the holding platform 5 reaches the corresponding rejector 6, the rejector 6 is actuated to make the push rod pop out, push the holding platform 5 to topple over, and reject the "mud shell" oysters.

[0038] like Figure 2 As shown, an electronic scale 7 is provided on the frame 1 .

[0039] Specifically, the electronic scale 7 can provide a high-precision weighing function to ensure that the weight of each object to be detected is accurately measured. When the material box 57 moves the oysters to the electronic scale 7, the electronic scale 7 automatically weighs them and transmits the results to the controller 2, which sorts and grades them according to the weighing results. In this embodiment, it is preferred to detect whether the oysters are "mud shell" oysters. If they are detected as "mud shell" oysters, they are preferentially removed, and after being detected as qualified oysters, they are graded according to the weight of the oysters.

[0040] like Figure 1 As shown, the frame 1 is also provided with lifting feet 11, and the corresponding supporting equipment can be adapted by adjusting the height of the lifting feet 11.

[0041] The present application discloses a weight grading scale with a metal detection function, which forms a closed path by setting a metal coil 51, a metal contact point 52, a metal signal plate 53, and a controller 2 to form a magnetic field detection device for detecting "mud shell" oysters. That is, when the "mud shell" oysters fall from the feeding device to the storage table 5, they will pass through the metal coil 51, generate magnetic field fluctuations and be converted into electrical signals, and the electrical signals will be transmitted to the controller 2 through the metal signal plate 53. After the controller 2 receives the electrical signal from the metal signal plate 53, the controller 2 analyzes and processes the received electrical signals according to the preset logic algorithm. When the controller 2 determines that it is a "mud shell" oyster, the controller 2 controls the storage table 5 to remove the "mud shell" oysters, thereby improving the efficiency and accuracy of sorting, realizing the removal of single unqualified oysters, and improving the use efficiency of existing equipment. The present application can not only be used to remove "mud shell" oysters, but also can be used to sort other items with metal characteristics.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
