All metal foreign substance detection device used for aluminum foil packed products

Abstract

The invention provides an all metal foreign substance detection device used for an aluminum foil packed products, relates to an all metal foreign substance detection technology for the aluminum foil packed products, and is suitable for performing all metal foreign substance detection on the aluminum foil packed products and general products. The all metal foreign substance detection device is composed of a sensor (probe), a detection signal receiving module, a detection signal processing module, a detection signal excitation module, a reference signal source, a central control unit, an IO module, a human-computer interface and a power supply system. The detection signal receiving module receives detection signals acquired by the sensor. The detection signals are processed through a detection signal automatic balancing circuit and then the signals are processed through the detection signal processing module so that reliability, stability and sensitivity of signal detection can be enhanced. The all metal foreign substance detection device is reasonable in structure, convenient to operate and great in detection effect so that the all metal foreign substance detection device can be used for all metal foreign substance detection of the aluminum foil packed products and all metal foreign substance detection of non-aluminum foil packed products with high "product effect" so that the all metal foreign substance detection device has great economic benefit.

Description

technical field [0001] The all-metal foreign body detection device that can be used for aluminum foil packaging products involves the full metal foreign body detection technology for aluminum foil packaging products, and is suitable for the full metal foreign body detection of aluminum foil packaging products and general products. technical background [0002] There are two main types of metal foreign matter detectors used in the food production process: one is the detection equipment using static magnetic field technology, which can only detect ferromagnetic metal particle foreign matter, but cannot detect copper and aluminum Foreign matter such as metal particles of non-ferromagnetic or weakly ferromagnetic materials. The other is to use electromagnetic field technology. Although this kind of equipment can be used to detect metal particles and foreign objects including iron, stainless steel, copper, aluminum and other metal materials, the detection signal reception and det...

Problems solved by technology

[0002] There are two main types of metal foreign matter detectors used in the food production process: one is the detection equipment using static magnetic field technology, which can only detect ferromagnetic metal particle foreign matter, but cannot detect copper and aluminum Foreign matter such as metal particles of non-ferromagnetic or weakly ferromagnetic materials

The other is to use electromagnetic field technology. Although this kind of equipment can be used to detect metal particles and foreign objects including iron, stainless steel, copper, aluminum and other metal materials, the detection signal reception and detection signal processing in this electromagnetic field technology detection equipment Insufficient, making it impossible to detect whether tiny metal particles are mixed in products packaged in aluminum foil due to the large "product effect" of the packaged product itself when testing products packaged in aluminum foil

[0003] Especially in food and other industries, more and more products are packaged in aluminum foil, and the tiny metal particles that may appear in the production process are mainly non-ferromagnetic or weakly ferromagnetic metals such as stainless steel. None of the equipment can effectively detect all metal foreign objects on products packaged in aluminum foil, which makes the generated products have great safety hazards
