Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a metal detector for food. Background Art

[0002] A metal detector is a metal detection device, which consists of a metal detector and an automatic rejection device, with the detector as the core part. The system can use the alarm signal to drive the automatic rejection device, etc., so as to exclude metal impurities from the production line. There are three sets of coils distributed inside the detector, namely the central transmitting coil and two equal receiving coils. The oscillator connected to the middle transmitting coil generates a high-frequency variable magnetic field. In the idle state, the induced voltages of the receiving coils on both sides cancel each other out before the magnetic field is disturbed and reach a balanced state. After the food production is completed, it needs to be tested with a metal detector.

[0003] Announcement No. (CN220346581U) discloses an automatic sorting food metal detector, which realizes metal detection by driving food through the metal detector body through the operation of a conveyor belt, and the detected food will continue to move under the action of the conveyor belt and pass through the distance sensor, at which time the position of the unqualified food will be located, and then the electric suction cup will move to the top of the unqualified food, and then the unqualified product will be picked out through the adsorption effect of the electric suction cup. The above device uses an electric suction cup to clean the unqualified products, but the electric suction cup can only adsorb products with a smooth surface, which has certain limitations and needs to be improved.
