Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a metal detection device. Background Technique

[0002] Metal detectors use the principle of electromagnetic induction to detect metals. All metals, including iron and non-ferrous metals, have high detection sensitivity. Usually, a metal detector consists of two parts, namely a metal detector and an automatic rejection device. Among them, the detector is the core part. Metal detectors are widely used in the detection of metal foreign objects in industries such as small foods, dried and fresh aquatic products, pasta, frozen foods, dried and fresh fruits and vegetables, etc., to detect various metal impurities such as iron and lead mixed or dropped in raw materials or products.

[0003] After retrieval, for example, a utility model patent with the Chinese publication number CN219943701U discloses a metal detection device for food processing. This device is provided with a first dividing plate and a second dividing plate to flatten the piled-up foods, so that small foods will not pile up when passing through the detector, thereby avoiding the situation of missed detection. At the same time, the conveyor belt is pressed by a pressing component so that the conveyor belt can still run smoothly under the condition of adjusting the height. However, this device needs to accurately adjust the pressing component to ensure that the conveyor belt can run smoothly and will not affect the normal rotation of the conveyor belt. The operation difficulty is relatively large. And through this device, only the articles can be flattened, but if the articles are arranged closely, it will still affect the detection result. Therefore, a metal detection device is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1-4 A metal detection device in this embodiment includes a conveying platform 1, a conveying belt 2 is arranged on the conveying platform 1, a metal detector body 3 is arranged on the conveying platform 1, and a flattening and dispersing mechanism 4 is arranged on the conveying platform 1.

[0025] Specifically, the conveyor belt 2 is driven on the conveyor platform 1, and the metal detector body 3 detects the food. This part is the prior art and has been disclosed in the patent document with announcement number: CN219943701U.

[0026] Specifically, the paving and dispersing mechanism 4 includes a mounting base 401. There are two mounting bases 401 installed on the top of the conveying table 1. An electric telescopic rod 402 is fixedly installed on the mounting base 401. The bottom of the electric telescopic rod 402 is installed with a mounting frame 403. The bottom of the mounting frame 403 is installed with two mounting plates 404. An installation groove 405 is opened on the outer wall of one mounting plate 404. A motor 406 is installed inside the installation groove 405. A rotating rod 407 is fixedly installed at the output shaft of the motor 406 on one side. A material distributing column 408 is fixedly installed at the output shaft of the motor 406 on one side. A threaded column 409 is fixedly installed on the outside of the rotating rod 407. A shifting rod 410 is threadedly connected to the outside of the threaded column 409. A threaded groove 411 is opened on one side wall of the shifting rod 410. When the food moves on the conveyor belt 2 towards the metal detector body 3, it will first be paved by the material distributing column 408. By controlling the electric telescopic rod 402 at the top of the material distributing column 408, the height of the material distributing column 408 can be adjusted according to the height of the food, so as to facilitate the material distributing column 408 to pave the piled-up food flat; the paved food then continues to pass through the shifting rod 410 to complete the dispersed transportation. The rotating shifting rod 410 will push aside the food that is closely attached. The food then passes through the space between the two shifting rods 410, so as to prevent the food from being arranged closely; and by setting a plurality of threaded columns 409, the distance between the shifting rods 410 can be adjusted according to the size of the food, so that the food can pass through smoothly.

[0027] Specifically, the rotating rod 407 is arranged at the bottom of the mounting base 401 near the metal detector body 3. The motor 406 is a damping motor. The damping motor rotates slowly, which can prevent the food from flying out of the conveyor belt 2.

[0028] During implementation, the following steps are taken for operation:

[0029] 1) First, place the food to be detected on the conveyor belt 2. The conveyor belt 2 will transport the food to the metal detector body 3. First, control the electric telescopic rod 402 according to the height of the food to adjust the heights of the material distributing column 408 and the rotating rod 407;

[0030] 2) Then start the motor 406 to drive the material distributing column 408 and the rotating rod 407 to rotate. During the conveying process, the material distributing column 408 paves the piled-up food flat to prevent the food pile from being too high;

[0031] 3) Finally, the paved food continues to pass through the shifting rod 410. The rotating shifting rod 410 will push aside the food that is closely attached. The food then passes through the space between the two shifting rods 410 and the dispersed food is detected by the metal detector body 3.

[0032] To summarize, the metal detection device, by providing a flattening and dispersing mechanism 4, when the food moves on the conveyor belt 2 toward the metal detector body 3, it will first be flattened by the dividing column 408; the flattened food will continue to pass through the toggle rod 410, and the rotating toggle rod 410 will push away the tightly fitted food, and the food will then pass through the toggle rod 410 through the space between the two toggle rods 410, thereby preventing the foods from being arranged too closely; and by providing a plurality of threaded columns 409, the distance between the toggle rods 410 can be adjusted according to the size of the food so that the food can pass smoothly.
