The weighing platform of the underground mine car is designed to ensure the accuracy and reliability of the weighing process. Based on the uniform distribution of force and accuracy requirements, four weighing modules are placed horizontally on the same plane. To ensure that the weighing sensor is only subjected to vertical force, the horizontal plate in the positioning seat is designed with an arc-shaped upper part, so that the weighing modules only experience vertical force when bearing the weight, thereby minimizing eccentric force.

The pit-type weighing system of the scale is equipped with a weighing body system, on-site computer terminals, cameras, hard disk recorders, switches, serial port instruments, switch quantity instruments, on-site lighting, LED display matrix screens, infrared beam switches, vehicle number recognition devices, and intercom systems. The main functions of the on-site control device of the scale: to determine whether the truck has completely loaded onto the scale, to automatically read the vehicle number information, and to obtain the weight data from the weighing instrument in real time through the RS485 protocol interface.

The lifting system of the weighbridge scale adopts a large-scale structure and realizes the lifting through the simultaneous lifting of multiple hydraulic jacks. The bearing capacity of the hydraulic jacks is collected by the weighing sensor, and the displacement value of the pile leg is collected by the displacement sensor. The platform is lifted to a certain distance to achieve this. The entire weight of the platform is supported by the hydraulic cylinders of the hydraulic jacks. The weight of each hydraulic cylinder is measured accurately, and multiplied by the working area of all the hydraulic cylinders to obtain the weight of the platform. The center of gravity position coordinate parameters of the structure can be obtained based on the coordinates of the hydraulic jacks.

The Gravity sorting machine utilizes dynamic weighing technology to detect the weight of the product, and the application of different weight sensors can get different detection accuracy of the weight testing machine, which determines the detection accuracy and operational stability of the weight grading machine. The range range of the weight sensor determines the weighing weight and scale of the weight grading machine. Meanwhile, the precision of the weight sensor also affects the precision of the weight sorter.

Scanning sorter can be integrated with various packaging production lines and conveyor systems, mainly used for on-line detection of whether the weight of the product is qualified or not, and whether there are missing parts in the package. Or according to the different weight of the items to be conveyed to the corresponding weight range area. Generally consists of control device, sorting device, conveying device and sorting roadway. The role of the control device is to identify, receive and process the sorting signal, according to the requirements of the sorting signal to instruct the sorting device, according to the variety of goods, according to the location of the goods delivered or according to the category of the owner of the goods for automatic classification.

The weight sorting machine can select the weight value that does not meet the requirements, and separate the weight mouth that does not meet the requirements with the conveyor belt and the stripping equipment, and the one that meets the requirements can be passed. It has included many functions needed today, and adopts the world's advanced digital weighing unit to achieve high-speed and stable measurement. The patented scale frame structure ensures accuracy and stability. Multi-mode LCD graphic display operating system, Chinese, English and Korean operation interface, easy to learn. Powerful data statistics function, record the detection data of each shift. The use of dump conveyor belt, convenient maintenance of automatic counting, automatic elimination of unqualified products or in case of unqualified products alarm. The test standard weight can be set, the test weight and quantity are displayed in real time, and the test results are displayed.

Weighing hopper machine detects and samples the weight of material in the metering hopper by the controller, and stops feeding when the weight of material in the metering hopper reaches the upper limit value set for dosage. It reads the main totalization, instantaneous flow rate, set flow rate, weighing instrument status and other related data from the weighing instrument. Weighing instrument status display (zero state, interval state, running state or alarm state), online monitoring and management by computer, with high requirements on weighing speed, weighing accuracy, system compatibility and expandability.

Weighing and feeding system as a whole is a mechanical and electrical integration equipment, the start and braking of the control part of the turntable, the identification of raw materials, opening, capping, weighing, pouring, calibration and so on are completed by the control system. The mechanical part and the control part form a good coordination, and the action is accurate. Advanced control, equipment modeling and process optimization technologies are adopted to realize complete sets of special systems for biological fermentation process, complete sets of special systems for synthetic reaction process and complete sets of special systems for extraction process. It provides a customizable and extensible industry control engineering algorithm library. Based on the unified modeling specification and supported by the batching architecture platform, the batching efficiency can be significantly improved through inheritance, derivation, reuse and reconfiguration mechanisms.

The explosion-proof volumetric scale can enable two or more different substances to be dispersed and mixed with each other, thereby achieving variable-frequency mixing and weighing. When the electronic scale is started for production, the PLC will send a dynamic measurement start signal to the weighing control instrument. The weighing instrument then begins to collect and display the weights of each stage, and adopts fast and slow opening in different weight stages. When the target value is reached, it outputs a stop measurement signal, which is controlled by the PLC to close the relevant valves, pumps, etc. above the scale. At the same time, the unloading action is completed, and the weighing control instrument automatically clears and resets the weight.
