Abstract
Description
Technical Field
[0001] This utility model relates to the field of food packaging inspection technology, and in particular to a metal detection device for oden meatball packaging. Background Technology
[0002] As a popular ready-to-eat food, oden meatballs can pose a serious health risk if metal impurities are introduced during the production and packaging process. This can affect product quality and may even cause serious harm to consumers' health.
[0003] Existing devices cannot quickly and effectively remove packages containing metal impurities during the detection process, affecting production efficiency. In addition, the detected packaging bags are not marked, and when there are errors or omissions in removal, packaging bags with metal impurities can easily be confused with those without metal impurities, reducing the practicality of the device. Therefore, a metal detection device for oden meatball packaging is proposed to address the above problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] A metal detection device for packaging oden balls includes a frame. From right to left, the frame is provided with a metal detection mechanism, an marking mechanism, and a collection mechanism. A conveyor belt is provided inside the frame. The bottom of both ends of the frame are vertically connected to the top of the support legs. A baffle is provided on the top of the right half of the frame side wall. The metal detection mechanism includes a first fixed frame fixed in the middle of the frame. A first hydraulic rod is mounted on the top of the first fixed frame. A metal detection module is mounted on the telescopic end of the first hydraulic rod. The marking mechanism includes a second fixed frame located to the left of the first fixed frame. A position detection sensor is mounted at the interval between the first fixed frame and the second fixed frame. A second hydraulic rod is mounted on the top of the second fixed frame. The telescopic end of the second hydraulic rod is fixedly connected to the top of a lifting plate. A marking block is provided on the bottom of the lifting plate.
[0006] Preferably, a paint box is provided at the top of the rear end of the lifting plate, and a corresponding hole and slot are provided on the top wall of the second fixing frame directly above the paint box. One end of the cotton thread is connected to the inside of the paint box, and the other end is connected to the inside of the marking block.
[0007] Preferably, the collection mechanism includes a fixed plate located on the front side of the left end of the frame, a third hydraulic rod inside the top of the fixed plate, the telescopic end of the third hydraulic rod being fixedly connected to the front side of the push plate, a collection frame corresponding to the rear of the push plate, and the top of the rear wall of the collection frame being welded to the bottom of the extended baffle.
[0008] Preferably, the extended baffle is provided with a telescopic buffer rod on the front side, the front end of the telescopic buffer rod is fixedly connected to the rear end of the buffer plate, and the bottom of the buffer plate is welded to the top of the inclined plate.
[0009] Preferably, the inside of the collection frame is a through structure, and hanging rods are provided at both ends of the bottom of the collection frame.
[0010] Preferably, a through-beam sensor is provided at the interval between the fixed plate and the second fixed frame. The through-beam sensor includes a signal transmitter and a signal receiver, which are respectively fixed to the top of the front and rear side walls of the frame.
[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) The third hydraulic rod extends and pushes the push plate to push the item into the collection box, so as to quickly and effectively remove the package containing metal impurities. The telescopic buffer rod and buffer plate set in the collection mechanism can effectively buffer the impact force when the item enters the collection box and reduce the possibility of damage to the item.
[0012] (2) The second hydraulic rod extends, causing the lifting plate and the label block to descend. Since the cotton thread connects the paint box and the label block, the paint will soak into the label block through the cotton thread, thereby marking the packaging with metal impurities and preventing the packaging with metal impurities from being confused with the packaging bag without metal impurities.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Please see Figure 1-4 This utility model provides an embodiment of a metal detection device for packaging oden balls, including a frame 1. From right to left, the frame 1 is equipped with a metal detection mechanism, a marking mechanism, and a collection mechanism. A conveyor belt 2 is installed inside the frame 1. The conveyor belt 2 is existing technology and will not be described in detail here. The bottom ends of both ends of the frame 1 are vertically connected to the tops of support legs 3. A baffle 4 is provided on the top of the right half of the side wall of the frame 1. The metal detection mechanism includes a first fixed frame 51 fixed in the middle of the frame 1. A first hydraulic rod 52 is mounted on the top of the first fixed frame 51, and a metal detection device is mounted on the telescopic end of the first hydraulic rod 52. The measuring module 53 and the marking mechanism include a second fixed frame 61 located to the left of the first fixed frame 51. A position detection sensor is installed at the interval between the first fixed frame 51 and the second fixed frame 61. A second hydraulic rod 62 is installed on the top of the second fixed frame 61. The telescopic end of the second hydraulic rod 62 is fixedly connected to the top of the lifting plate 63. A marking block 64 is provided at the bottom of the lifting plate 63. A paint box 65 is provided at the top of the rear end of the lifting plate 63. A corresponding hole and slot 67 is provided on the top wall of the second fixed frame 61 directly above the paint box 65. One end of the cotton thread 66 is connected to the inside of the paint box 65, and the other end is connected to the inside of the marking block 64.
[0022] The item to be inspected is placed at the right end of conveyor belt 2. Conveyor belt 2 is started, and the item moves from right to left. When the item moves below the first fixed frame 51, the first hydraulic rod 52 extends, bringing the metal detection module 53 closer to the item for metal detection. The height of the metal detection module 53 can be adjusted according to the height of the packaging bag. If metal is detected, the item information is recorded. The item continues to move to the left. When the position detection sensor detects the item's position, the time it takes for the packaging bag to reach the second fixed frame 61 can be determined based on the speed of conveyor belt 2. When the packaging bag reaches the second fixed frame 61, the second hydraulic rod 62 extends, causing the lifting plate 63 and the marking block 64 to descend. Since the cotton thread 66 connects the pigment box 65 and the marking block 64, the pigment will seep into the marking block 64 through the cotton thread 66, thus marking the packaging containing metal impurities. After marking, the second hydraulic rod 62 retracts, and the lifting plate 63 and the marking block 64 return to their original positions.
[0023] The collection mechanism includes a fixed plate 71 located on the front left side of the frame 1. A third hydraulic rod 72 is located inside the top of the fixed plate 71. The telescopic end of the third hydraulic rod 72 is fixedly connected to the front side of a push plate 73. A collection frame 74 is located correspondingly behind the push plate 73. The top of the rear wall of the collection frame 74 is welded to the bottom of an extended baffle 75. A telescopic buffer rod 76 is located on the front side of the extended baffle 75. The front end of the telescopic buffer rod 76 is fixedly connected to the rear end of a buffer plate 77. The bottom of the buffer plate 77 is welded to the top of an inclined plate 78. The collection frame 74 has a through-type internal structure. 4. Hanging rods 79 are provided at both ends of the bottom. A through-beam sensor is provided at the interval between the fixed plate 71 and the second fixed frame 61. The through-beam sensor includes a signal transmitter and a signal receiver, which are respectively fixed to the top of the front and rear side walls of the frame 1. When the marked item moves to the interval between the fixed plate 71 and the second fixed frame 61, if the signal receiver of the through-beam sensor does not receive the signal emitted by the signal transmitter, it means that the item has arrived at this location. When the signal receiver signal is interrupted and then reconnected, it means that the packaging bag has reached the rear side of the push plate 73. At this time, the third hydraulic rod 72 extends, pushing the push plate 73 to push the item into the collection box 74. When the item enters the collection box 74, it will first hit the buffer plate 77. The telescopic buffer rod 76 plays a buffering role to avoid damage to the item. The item will eventually slide down the inclined plate 78 to the bottom of the collection box 74. The hanging rods 79 can be used to hang the collection bag for easy collection of oden balls.

Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
