A Conveyor Belt Metal Detector Through Highly Automatic Adaptation

Abstract

The invention relates to the technical field of food production, and discloses a conveyor belt-type metal detector that automatically adapts to the height, including a fixed bracket, a control box is fixedly installed on the front of the fixed bracket, and a control box is fixedly installed on both sides of the fixed bracket. There is a decorative plate, a drum is movable inside the decorative board, and a conveyor belt is connected between the two drums, a detection bridge is provided directly above the conveyor belt, and a device is installed on the top of the detection bridge. cavity. The conveyor belt-type metal detector that automatically adapts to the height, through the installation of the detection bridge driven by the electric push rod, can make the detection bridge realize the automatic adjustment of the height, and is equipped with an infrared sensor, through the distance sensing of the infrared sensor, in the product When the detection bridge cannot be passed, the height of the detection bridge can be adjusted by lifting the electric push rod, so that different products or different volumes will not affect the passability, making the metal detector more adaptable.

Description

technical field [0001] The invention relates to the technical field of food production, in particular to a conveyor-belt-type metal detector with automatic height adaptation. Background technique [0002] A metal detector is a device that can automatically detect whether a product contains metal substances. It is used in various fields such as food, medicine, and cosmetics to provide a reliable guarantee for product quality. [0003] The working principle of the metal detector is to use the principle of electromagnetic induction, using the alternating current to pass through the coil to generate a rapidly changing magnetic field. This magnetic field can induce eddy current inside the metal object, and the eddy current will generate a magnetic field, which in turn affects the original The magnetic field causes the detector to beep. [0004] During the working process of the metal detector, the product is transported to the bottom of the detection device through the conveyor ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a conveyor-belt-type metal detector that automatically adapts to the height, which has the advantages of the height of the detection device automatically adapting to different product volumes, strong adaptability, folding the pressing arm to reduce the height of the conveyor belt and further increasing the passing space, which solves the existing problems The detection devices are all fixedly installed directly above the conveyor belt through the detection bridge, and the volume of the product is uncertain, so the fixed detection device is likely to cause the product to fail to pass the detection directly below the detection bridge, resulting in product It is frequently stuck in the process of transportation, which further leads to the problem that the operation of the metal detector is more cumbersome.
