Conveying belt type metal detector capable of automatically adapting through height

Abstract

The invention relates to the technical field of food production, and further discloses a conveying belt type metal detector capable of automatically adapting through the height. The detector comprisesa fixing support, a control box is fixedly installed on the front face of the fixing support, decorative plates are fixedly installed on the two sides of the fixing support, rotary drums are movablyinstalled in the decorative plates, a conveying belt is in transmission connection between the two rotary drums, a detection bridge is arranged over the conveying belt, and a device cavity is formed in the top of the detection bridge. According to the conveying belt type metal detector capable of automatically adapting through the height, the detection bridge driven by an electric push rod is arranged, the height of the detection bridge can be automatically adjusted; and an infrared sensor is matched, the height of the detection bridge is lifted and adjusted through the electric push rod whenthe product cannot pass through the detection bridge through distance induction of the infrared sensor, the passing ability of different products or different sizes cannot be affected, and the adaptability of the metal detection machine is higher.

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.
