Description of important accessories of automatic checkweigher
The automatic checkweigher sold by Guangdong Kenwei Co. , Ltd. is a checkweigher for medium and low speed and high precision packaging production lines. It can be integrated with various packaging production lines and conveying systems, and is mainly used for on-line inspection of product weight. Whether the component or product weight file is missing in the package. The principle is that the packaged product passes through the weighing platform at a certain speed and measures the weight value of the product during transportation. The unqualified product is rejected by the actuator. The hardware system is the physical foundation of the whole measurement and control system. According to the functional requirements of the measurement and control system, the hardware system is constructed and optimized. The hardware of the system mainly includes the following parts: computer, signal detection part, signal conditioning circuit, data acquisition card part, control part and actuator. (1) Computer: data acquisition, data management and control decision center of the whole measurement and control system. (2) Signal detection part: mainly refers to two high-precision pressure sensors, which are responsible for real-time conversion of dynamic weighing quality signals and transmitting the converted electrical signals to the data acquisition board part. (3) Signal conditioning circuit: amplify, excite, linearize, isolate and filter the signal. (4) Data acquisition card part: Includes data acquisition card and its supporting equipment, which conduct A/D conversion to the collected data and transmit it to the computer for further analysis and processing; Then the control result output by the computer is converted to the control part through D/A conversion. (5) Weighing Display Controller: The computer processes according to the control setting parameters, obtains the control result through a certain control algorithm, and sends the control result to the actuator. The weighing display control instrument displays 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 parts, overweight quantity, overweight quantity and qualified parts quantity. The display controller can also carry various statistical information, and can use communication interfaces to network useful information to management computers or print reports through printers. (6) Execution of the rejection device: according to the packaging form and characteristics of the inspected object, the rejection device can be divided into many methods such as pushing, turning and carrying. The actuator performs corresponding actions according to the control results and eliminates the quality that does not meet the standards in time. Packaging products. Automatic checkweigher is mainly used in various automatic packaging production lines; Online and offline identification or weighing grade selection are widely used in online high-speed packaging inspection and weighing applications in pharmaceutical, food, health care products, daily chemical, battery, light industry and other industries.
