Detection machine for detecting whether packaged food contains deoxidizing agent or not and detection method thereof

Abstract

The invention relates to a detection machine for detecting whether packaged food contains deoxidizing agent or not and a detection method thereof. The detection machine comprises a machine frame and a conveying device which is installed on the machine frame. A material sensor, a deoxidizing agent sensor and a cleaning mechanism are arranged on the machine frame. When the material sensor detects that when the packaged food to be detected passes, a trigger signal is sent to a timing switch controller which is arranged on the machine frame, a timer of the timing switch controller is triggered to begin timing, and the timer presets timing value T. When the deoxidizing agent sensor detects the packaged food containing the deoxidizing agent, a reset signal is sent to the timing switch controller. The cleaning mechanism is used for popping packaged food without the deoxidizing agent out of the conveying device, and power-on action or power-off waiting of the cleaning mechanism is controlled by the timing switch controller. Automation detection is adopted by the detection machine, so that the detection machine is high in efficiency, low in labor intensity, simple in structure and low in manufacturing cost and saves cost. The detection method is accurate and reliable, easy to achieve and high in efficiency.

Description

Technical field: [0001] The invention relates to a detection machine and a detection method for detecting whether deoxidizer is contained in packaged food. Background technique [0002] As a new material for food preservation, deoxidizer has its unique advantages and is widely used in the food industry. The deoxidizer and the food are packed in the same packaging bag, which absorbs the oxygen in the packaging bag, making the container anaerobic, and the food can be preserved. Deoxidizers generally use reduced iron powder as the basic raw material, and are used in food packaging bags that generally need to be kept fresh, which can maintain food quality and extend shelf life. [0003] After the food is packaged in the packaging bag, in order to detect whether the deoxidizer has been put into the food packaging bag, the detection method currently used is generally that the food production personnel visually observe each packaging bag, and then remove the deoxidizer from the pa...

This detection method is not only inefficient, but also prone to errors due to eye fatigue transition caused by long-term detection

[0004] Now, there are mechanical automatic deoxidizer detectors that have appeared on the market, such as the utility model patent entitled "A Deoxidizer Detector in Food Packaging Bags" (Patent No. ZL201120283407.1) authorized by the applicant. Metal detectors, such as electromagnetic induction metal detectors, use a coil with alternating current to generate a rapidly changing magnetic field. This magnetic field can induce eddy currents inside metal objects, and eddy currents will Generate a magnetic field, which in turn affects the original magnetic field, thereby detecting the presence or absence of metal. On the one hand, this kind of metal detector has a complex structure, with a dedicated induction switch, microprocessor MCU, display screen and control circuit board, with many parts and low cost. Higher, it is difficult to popularize and apply in the market on a large scale. On the other hand, the existing mechanical automatic deoxidizer detection machine can only detect the deoxidizer or no deoxidizer in the packaged food. However, in fact, there is another The unavoidable situation is that the deoxidizer contained in the packaged food has already failed, which is the same as if no deoxidizer is put in, and the existing detector cannot detect the deoxidizer that has failed
