Description

Technical Field

[0001] This utility model relates to the field of food safety technology, and in particular to a food detection device for metal foreign objects. Background Technology

[0002] A metal foreign object detection device is a tool used to detect whether food contains metal impurities. It is an important tool in the field of food safety and quality control. This device can effectively identify and separate food products contaminated with metal foreign objects, ensuring that the food that ultimately reaches consumers is safe and harmless.

[0003] Existing metal foreign object detection devices typically stop the conveyor belt when they detect a metal foreign object, and then the food containing the metal foreign object is manually removed by staff. Another method is to reverse the conveyor belt to remove the food containing the metal foreign object from the production line. However, both methods cause interruptions in the food detection process and cannot achieve a continuous and uninterrupted detection process. This not only reduces production efficiency but also increases the need for manual intervention, which may lead to higher operational error rates and time costs.

[0004] To address the aforementioned issues, there is a need for a food detection device capable of continuous detection of metallic foreign objects. Utility Model Content

[0005] In order to overcome the shortcomings of poor detection continuity and slow efficiency in food testing, this utility model provides a food detection device for metal foreign objects.

[0006] The technical solution of this utility model is as follows: A metal foreign object food detection device includes a frame, a belt conveyor, a mounting frame, and a metal detector. The belt conveyor is installed inside the frame, the mounting frame is installed on the frame, and the metal detector is installed on the mounting frame. It also includes a connecting plate, a collection frame, a mounting plate, a motor, a rotating shaft, a push plate, a connecting frame, a pulley, and a guide frame. The connecting plate is connected to the right side of the frame, and the collection frame is placed on the connecting plate. The mounting plate is installed inside the mounting frame, and the motor is installed on the mounting plate. The output shaft of the motor passes through the mounting plate and is connected to the rotating shaft. A first sliding groove is opened on the rotating shaft, and a push plate is slidably connected in the first sliding groove. The connecting frame is connected to the push plate, and a pulley is rotatably connected in the connecting frame. A guide frame is connected to the front side of the mounting frame, and the pulley contacts and cooperates with the guide frame.

[0007] Optionally, it also includes a two-way lead screw, a limiting plate, and a protective pad. The two-way lead screw is rotatably connected inside the push plate. The push plate has symmetrical second slide grooves on the left and right sides. The limiting plates are slidably connected in both second slide grooves. The two limiting plates are screwed to the two-way lead screw. The inner sides of the two limiting plates are connected to protective pads.

[0008] Optionally, it also includes a rotating rod, with the left end of the bidirectional lead screw connected to the rotating rod.

[0009] Optionally, it also includes guide plates, which are symmetrically connected to the left and right sides of the frame.

[0010] Optionally, the guide frame is arc-shaped, with its center aligned with the axis of rotation.

[0011] Optionally, the guide plate can be tilted at an angle of forty degrees.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a connecting plate, a collection box, a mounting plate, a motor, a rotating shaft, a push plate, a connecting frame, pulleys, and a guide frame, this device can detect food containing metal foreign objects by simply stopping the belt conveyor. Then, the motor starts and drives the rotating shaft to rotate, which in turn drives the push plate connected to it to move along the guide frame. During this process, the push plate can accurately push the food containing metal foreign objects from the conveyor belt into the collection box, realizing a fast and automated removal operation. This not only avoids the trouble of manual intervention or reversing the belt conveyor in traditional methods, but also ensures the continuity and efficiency of the production line.

[0013] 2. By setting up a bidirectional lead screw, limiting plates, and protective pads, limiting plates can be added to both sides of the push plate. The width between the limiting plates can be flexibly adjusted through the bidirectional lead screw, ensuring the stability and accuracy of the push plate during operation. It can also be quickly adjusted according to different food sizes or production line requirements. Attached Figure Description

Detailed Implementation

[0020] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0021] Example: A device for detecting metal foreign objects in food, such as Figures 1-5 As shown, the system includes a frame 1, a belt conveyor 2, a mounting frame 3, a metal detector 301, a connecting plate 302, a collection frame 303, a mounting plate 4, a motor 5, a rotating shaft 6, a push plate 8, a connecting frame 9, a pulley 10, a guide frame 11, a two-way lead screw 12, a limit plate 14, a protective pad 15, and a rotating rod 16. The belt conveyor 2 is installed inside the frame 1 for transporting food. The mounting frame 3 is mounted on the frame 1, and the metal detector 301 is installed in the middle of the mounting frame 3. The connecting plate 302 is fixedly connected to the right side of the frame 1, and the collection frame 303 is placed on top of the connecting plate 302 for collecting food containing metal foreign objects. The mounting plate 4 is installed on the right inner wall of the mounting frame 3, and the motor 5 is installed on top of the mounting plate 4. The output shaft of the motor 5 passes through the mounting plate 4 and is connected to the rotating shaft 6. The rotating shaft 6 has a first sliding groove 7, and the push plate 8 is slidably connected within the first sliding groove 7. The connecting frame 9 is connected to the top of the push plate 8. A pulley 10 is rotatably connected inside the connecting frame 9. A guide frame 11 is fixedly connected to the front side of the mounting frame 3. The pulley 10 and the guide frame 11 are in contact and can be used to guide the pulley 10, thereby realizing the lifting and lowering movement of the push plate 8. The guide frame 11 is arc-shaped, and its center is consistent with the rotating shaft 6, which facilitates the lifting and lowering of the push plate 8. A double-acting screw 12 is rotatably connected inside the push plate 8. The push plate 8 has two symmetrically opened second slide grooves 13. Limit plates 14 are slidably connected in both second slide grooves 13. The two limit plates 14 are screwed to the double-acting screw 12. The limit plates 14 can limit the food. The inner side of the two limit plates 14 is connected to a protective pad 15 to protect the food. A rotating rod 16 is connected to the left end of the double-acting screw 12 to facilitate the rotation of the double-acting screw 12. Guide plates 17 are symmetrically connected to the left and right sides of the frame 1. The tilt angle of the guide plates 17 is forty degrees, which facilitates the guiding of the food.

[0022] When metal foreign object detection is required on food, the operator first rotates the rotating rod 16, which drives the bidirectional lead screw 12 to rotate. The rotation of the bidirectional lead screw 12 causes the two limiting plates 14 to move inward along the second slide groove 13. When the limiting plates 14 move to the appropriate position, the rotating rod 16 is stopped. Then, the belt conveyor 2 and the metal detector 301 are started. At this time, the operator can place the food on the belt conveyor 2. The two guide plates 17 guide the conveyed food. The belt conveyor 2 transports the food backward. When the food is conveyed to the bottom position of the metal detector 301, the metal detector 301 can detect the food. If a metal foreign object is detected, the belt conveyor 2 will automatically shut down and the motor 5 will automatically start. The output shaft of the motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives all the components on it to move. When the push plate 8 drives the connecting frame 9 and the pulley 10 to rotate to a certain position, it will move downward along the inclined surface on the guide frame 11, causing the push plate 8 to move downward along the first slide groove 7. When the pulley 10 When the push plate moves to the bottom of the inclined surface of the guide frame 11 and disengages from it, it simultaneously moves to the bottom of the first chute 7 and contacts the belt conveyor 2. When the push plate 8 rotates to a certain position, it pushes the food on the belt conveyor 2 to move. Then, the push plate 8 pushes the food to rotate along the rotating shaft 6 to a certain position and pushes the food into the collection box 303 for collection. Then, the motor 5 drives the rotating shaft 6 to reverse. When the push plate 8 reverses to a certain position, the pulley 10 contacts the guide frame 11 and moves it upward along the inclined surface of the guide frame 11. At the same time, the push plate 8 moves upward along the first chute 7. When the push plate 8 rotates to its original position, the motor 5 automatically shuts off, and then the belt conveyor 2 automatically starts. If the metal detector 301 does not detect any metal foreign objects, the belt conveyor 2 will continue to transport the food. The above operation can be repeated to continuously place the food to be tested on the belt conveyor 2 for metal foreign object detection. After the food detection is completed, the belt conveyor 2 and the metal detector 301 can be turned off.

[0023] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
