working principle

The raw material will inevitably be mixed with metal, and once the metal into the production line, it will cause damage to the equipment. In order to ensure the normal operation of the production line, it is very important to remove the metal in the raw fish.

Metal detector is used to solve the above problems, its working principle is:
when the raw material passes through the detection channel of the metal detecting head, it falls into the bottom screw conveyor, which keeps turning in a positive rotation direction and sends the raw material to the next equipment in the production line. Once the metal material is detected in the passing raw material, the metal detection control system immediately manipulates the bottom screw conveyor to implement the reverse action and send the metal and part of the raw material to the rear exit. After the completion of the above work, it will automatically return to the normal detection and conveying working state, so as to realize the purpose of the raw material for metal detection.

Structure

(1)Metal detection head
Metal detection head is used to detect metal impurities in the material, in different working conditions can set different metal detection sensitivity, to meet the needs of different working conditions.
(2)Screw Conveyor
The screw conveyor is used to convey the raw material after the metal detector channel. The positive direction realizes the normal conveying of the raw material; when the raw fish is mixed with metal impurities, the convey will take reverse rotation, then the metal impurities will be pushed out from the other exit together with some materials. The positive and reverse movement of the screw conveyor is controlled automatically by the metal detectors according to the actual working condition.
(3)Basement
The basement is a bracket used to support the fixed metal detector head and screw conveyor.
