An intrinsically safe explosion-proof Electronic scale is a tool that uses Hooke's law or the lever principle of force to determine the mass of an object. When an object is placed on the scale, pressure is applied to the weighing module, causing deformation of the weighing sensor and a change in impedance. At the same time, a change in excitation voltage is used to output a changing analog signal. The signal is amplified by an amplification circuit and output to an analog-to-digital converter. Convert it into a digital signal that is easy to process and output it to the CPU for operation and control. The CPU outputs this result to the display based on keyboard commands and programs until it is displayed. Existing electronic scales are generally independent, meaning that signal acquisition, processing, and result display are all implemented within one module and cannot communicate with external systems, meaning they cannot be used in conjunction with external systems. Explosion proof electronic scales are equipment that can automatically complete raw material batching, with multiple advantages such as improving production efficiency, reducing labor costs, and ensuring product quality. Among them, the explosion-proof electronic scale is an important component of the feeding system and one of the core components of the entire system. Its main function is to achieve accurate weighing of raw materials. It mainly consists of a mixing system, feeding section, discharging section, control cabinet, variable frequency motor, frequency converter, Weighing system, and control operation panel. Using PLC to control material ratio, using the output of frequency converter to control motor speed, operating the control panel to intuitively display motor speed and process, the entire system can display and control the mixing and blending process of various materials in the production process.

The weighing scale adopts a weighing platform, a support frame, and a weighing instrument. The support frame is used to connect the weighing platform and the weighing instrument. The weighing sensor is installed inside the weighing platform and connected to the weighing instrument. The weighing platform adopts a load-bearing frame, a bottom plate set at the bottom of the load-bearing frame, and a panel set at the upper part of the load-bearing frame. A weighing platform is set between the bottom plate and the panel. The bottom plate and the panel of the weighing platform are welded, and the panel and the bottom plate are interlocked with the load-bearing frame. The weighing scale adopts a frame shaped weighing body, a platform located at the upper end of the frame shaped weighing body and hinged to one side of the frame shaped weighing body, a reinforcing beam located in the middle of the frame shaped weighing body, steel ball spring locking pins located on the inner wall of the front end of the frame shaped weighing body and distributed on both sides of the front end of the reinforcing beam, a pair of fixed brackets located on the inner wall of the rear end of the frame shaped weighing body, each fixed bracket is hinged to the piston rod of a cylinder, and the top of each cylinder body is hinged to a fixed plate fixed on the bottom surface of the platform. The front end of the fixed plate is suitable for cooperating with the steel ball spring locking pin to lock the platform and the frame shaped weighing body; The bottom of the four corners of the frame scale body is equipped with scale feet, and one end of each scale foot is equipped with a weighing sensor, which is fixed to the bottom of the frame scale body by bolts; There are multiple cable joints connected to each sensor on the inner wall of the frame shaped scale body, and a junction box is provided on the reinforcing beam; The junction box is equipped with an intelligent control circuit, and the detection signal terminal of the intelligent control circuit is connected to the cable joint.
