The operator of the mixer inputs the proportion of each raw material, the machine will calculate the weight of each raw material by combining the weight of each ingredient, and then control the opening and closing of the metering valve to distribute the raw materials to the weighing hopper, when each raw material is completed in accordance with the proportion of the raw material, the raw material in the weighing hopper will be discharged to the lower part of the agitator for stirring, and after the completion of the mixing, the whole process is complete.

Electronic crane scale through the load loading hook action on the sensor, so that the explosion-proof sensor elastomer undergoes a small change, the explosion-proof sensor is converted into the corresponding analog voltage signal transmitted to the data acquisition board, through the amplification, filtering, A/D converted into the corresponding digital signals, through the wireless transmission system to the instrumentation of the data processing board to obtain the corresponding weight data.

RFID intelligent warehousing weighing system application technology reasonable use of the workshop's existing space, the use of space utilization is also part of the cost savings, combined with including RFID tags, fixed read-write, antennae, hand-held terminals, open weighing management channel. Choose according to the actual site requirements. Realize the integrated information weighing management process from printing orders, picking, scanning packages, orders for shipment, as well as redeployment and sorting, return to the factory shipment and other processes for data transmission and reading. Realize accurate in and out of the warehouse, quantity inventory management, RFID tags and read-write mutual application makes all automation complete.

The RFID system introduces RFID technology into the existing warehouse management, and automatically collects the data of each operation link, such as warehouse arrival weighing, inspection, warehousing, warehousing, allocation, warehouse transfer, inventory counting, etc., to ensure the speed and accuracy of data input in each link of warehouse weighing management, to ensure that enterprises can grasp the real data of inventory in time and accurately, and to maintain and control enterprise inventory reasonably. Through scientific coding, it is also convenient to manage the batch and shelf life of items. Using the location management function of RFTD warehouse weighing system, we can know the current location of all inventory materials in time, which is conducive to improving the efficiency of warehouse management.

On-line laser coding and weighing is to put the marked object on the platform of electronic scale, and the laser is concentrated on the surface of the marked object with high energy density. By burning and etching, the substances on the surface of the marked object are vaporized, and by controlling the effective displacement of the laser beam, patterns or characters can be accurately burned.

The on-line laser coding and weighing control unit can control the light output of the laser and the angular deflection of the vibrating mirror, and can collect the speed of the production line in real time to generate a speed error compensation signal. The weighing operation unit is responsible for the man-machine interaction between the system and the operator. Through the weighing operation unit, the operator can compile user-defined codes and control the operation and stop of the system. After the weighing operation unit accepts the relevant operation of the operator, it will be forwarded to the main control unit for execution.

Explosion-proof batching machine is a very important process in the chemical production process of electronic scales, mainly to complete the weighing and proportioning of the main material and various ingredients. After the batching of the former system will be formed by the base powder through the spiral scale and conveyor sent to the premixer and the raw materials mixed by the conveyor sent to the finished product warehouse. The post-batching realizes the measurement of the flow of the conveyed materials.

The dosage machine is mainly a weighing instrument, PLC as an auxiliary control system, computer human-machine interface to display the proportioning parameters (formula) and monitor and record the real-time data. In automatic control mode, by clicking the "Start" button of automatic dosage in the pre-dosage process screen or the "Start" button of the pre-dosage control cabinet, the weighing instrument opens the weighing valve of the electronic scale according to the set recipe. If the system detects that the dosage valve of a scale is not closed, an alarm occurs and the scale enters the pause state. Each scale has an advance quantity according to the weighing speed. When the control instrument detects that the weighing weight of the scale reaches the set value, the advance quantity will be subtracted and the control instrument will close the feeding valve. The amount of advance can be corrected manually or automatically, so that the control instrument can control the dosage scale to reach the set target value every time the dosage accuracy.

Weighing and batching machine puts the weighed raw materials into the reactor in a certain order, and at the same time turns on the stirring and heating, the control process is completed by the weighing instrument and PLC together. The weighing instrument controls the dosing range, and the weight reaches the target value which is automatically completed by the PLC control valve, and there are two control modes of fixed order and programmable program for the dosing. In the fixed order mode, the discharge order of all kinds of raw materials is fixed and cannot be changed. In programmable mode, the feeding order of various raw materials can be set according to the recipe on the human-machine interface.
