Take you to understand the structure of the automatic checkweigher

Automatic checkweigher is a pipeline automatic weighing equipment. It is mainly composed of a conveyor (Measurement part) , Weighing sensor, display controller and other parts. First, the conveyor conveyor is composed of a conveying device and a weighing unit. There are many forms of conveyors, and belt type, chain type or roller type can be selected according to the form of the objects to be transported. The size of the conveyor depends on the size of the weighed object. The checkweigher weighing table itself is an independent small conveyor, which weighs the articles instantly through the conveyor. Because it is a dynamic measurement, the measurement speed is higher. The transmission part of the conveyor adopts a three-in-one electric drum, which can make the scale compact in structure, reasonable in layout and beautiful in appearance. Second, weighing sensors, weighing sensors also have a variety of forms, such as: differential transformer type, resistance strain type and electromagnetic balance type. The automatic checkweigher adopts the most widely used resistance strain sensor, which has the advantages of low price, many product types and good stability. The weighing platform composed of the conveyor is placed on the sensor, and the number of sensors is determined according to the size of the weighing platform. The table top with large weight and size is supported by four sensors, with stable and reliable performance; A single sensor can be used to support the table with small range and small size. Third, the display controller 'display instrument' amplifies, calculates and processes the weight signal sent by the weighing sensor, digitally displays the weight value, and compares the weight data with the preset value, then it sends out control signals of underweight, overweight and qualification. The limit values for underweight and overweight can be set manually. The display control instrument can display the difference between gross weight, net weight, last weighing value, last weighing value and set nominal value. It can also display the total number of weighed pieces, the number of underweight pieces, the number of overweight pieces, and the number of qualified products. The display controller can also transmit a variety of statistical information, and can network useful information to the management computer through the communication interface or print out reports through the printer. Fourth, the rejection device (Optional) According to the packaging form and characteristics of the inspected articles, the rejection device can be divided into various methods such as pushing out, tilting down, handling, diversion, etc. to exclude the detected unqualified articles from the production process.
