The sorting scale is a dynamic weight signal processing system for high-speed and high-precision online weighing equipment. With rich software, electronic, and mechanical options, this series can meet the online weighing requirements of various industries. The modular design makes the operation and daily maintenance of this series very simple. The product components are easy to disassemble and clean with water, using imported electrical components with waterproof performance and a simple operating surface. It can store parameters for 100 different weight specifications of materials, making it easy to operate and use. Built in report statistics, reports can be generated in EXCEL format, and various real-time data reports can be automatically generated; The USB flash drive can store statistical data for more than 1 year, keeping track of production status at any time; Reserved standard interfaces for easy data management, capable of communicating and networking with PCs and other smart devices; Realize centralized control: It can achieve centralized control of multiple weight inspection machines through one computer/human-machine interface; Parameter recovery function: Provides factory parameter setting recovery function. When in use, the material is weighed by the sorting scale body, and then the weight sensed by the sorting scale body on the material conveyor belt is transmitted to the external controller. The external controller starts the corresponding cylinder, which drives the push plate to move forward. The push plate pushes the material into the collection shell through the drainage plate. Due to the gravity of the material, the collection shell drives the connecting plate to move downward through the movable plate, and the connecting plate presses the connecting spring downward. The movable plate presses the buffering spring to move, thus playing a shock-absorbing effect.

The sorting scale includes a weighing module, a sorting mechanism, and a shock-absorbing mechanism. The left side of the top of the weighing module is fixedly connected to the sorting scale body. The sorting mechanism is set on the top of the weighing module, and the shock-absorbing mechanism is set on the sorting mechanism. The sorting mechanism includes a support plate and a fixed plate. The support plate is respectively installed on the top of the weighing module, and the top of the support plate is fixedly connected to the top of the weighing module between the support plates. The top of the fixed plate is fixedly connected to the rear side of the conveyor scale body. The top of the back of the top plate is fixedly connected to a cylinder, and the front side of the cylinder penetrates the top plate and extends to the outside. The front side of the cylinder is fixedly connected to a push plate, and the front side of the fixed plate top is fixedly connected to the corresponding position of the push plate The block, The top of the fixed block is fixedly connected to a drainage plate that is used in conjunction with the push plate. The bottom of the front of the fixed plate is provided with a movable plate, and the side of the movable plate near the fixed plate is slidably connected to the fixed plate. A collection shell is set at the top of the movable plate and the corresponding position of the drainage plate. The bottom of the collection shell is fixedly connected to a slider, and the top of the slider is provided with a sliding rod. The bottom end of the sliding rod extends through the slider to the outside and is fixedly connected to the top of the movable plate. The bottom of the collection shell is in contact with the top of the movable plate, and the bottom of the slider is in contact with the top of the movable plate. The control method of the cylinder is controlled by an external controller that is matched with.

Working principle of weight inspection machine:

When the material is transported to the center of the weighing platform, pressure is applied to the weighing sensor, causing deformation of the sensor and a change in impedance. At the same time, the excitation voltage is changed to output a changing analog signal.

The signal is amplified by an amplification circuit and output to a specially designed analog-to-digital converter, which converts it into a digital signal that is easy to process and outputs it to a proprietary microprocessor for operation and control.

Output this result to the display based on keyboard commands and algorithms, displaying the weight data of the item.

The dynamic Weighing system composed of weighing sensors and other components for weighing objects in motion is not a closed-loop automatic control system, but a dedicated data acquisition system.

Based on the signal characteristics and values provided by the dynamic weighing control system, the direct current component proportional to the mass is separated. Therefore, the current dynamic weighing method can be said to be mainly based on signal processing.
