In the quantitative weighing device, the hybrid Weighing system places the electric motor-driven screw feeding mechanism (commonly known as the auger motor) between the silo and the hopper. This mechanism is integrated with an electronic control device to achieve dynamic quantitative weighing of powder and granular materials. When the auger motor is activated, the powder and granular materials in the silo will rotate with the screw feeding mechanism and enter the hopper. Three strain-type Weighing modules are installed between the hopper and the weighing frame. The weight of the hopper is directly converted into an electrical signal by this weighing module group and sent to the electronic control device. When the set weight value is reached, the auger motor is shut off to stop feeding, and the hopper door is opened to discharge the material, thus completing a dynamic weighing and feeding process. The weighing system has accumulated excellent technologies and experience in various aspects such as bag opening, material discharge, transportation, measurement, proportioning, and filling of powders under different environments. It has carried out technical modifications to the original feeding system and has put forward various requirements for data acquisition, automatic control, operation monitoring, and operation management. The weighing control system uses explosion-proof Electronic scales to achieve precise control of the mixing process. By using negative pressure to suck the materials into the feeding pipeline, the materials are driven to be transported to the destination. 

At the top of the mixing and weighing system frame, there are several storage bins. Below the storage bins is a discharge chute, and below the outlet of the discharge chute is a vibrating Feeder. The feeding port of the vibrating feeder is located above the storage bin scale. Below the outlet of the storage bin scale is a discharge chute, and at the outlet of the discharge chute, there is a bag clamping device. The storage bin scale is connected to the weighing module, and at the outlet of the storage bin scale, there is an arc-shaped door. At both ends of the arc-shaped door, there are upper and lower connecting plates respectively. The upper and lower connecting plates are rotatably connected to the storage bin scale through bearings. The connecting plates are connected to the cylinder, and the cylinder is connected to the control system. The control system is connected to the weighing module and the vibrating feeder. The material is classified and separately loaded into different storage bins, and the material is weighed simultaneously to improve the weighing efficiency. The weighing module monitors the weight of the material and realizes precise weighing. The vibrating feeder supplies materials simultaneously, making the material mixing more uniform. 

The mixed weighing system is equipped with multiple storage tanks, each of which contains various raw materials. When the machine starts operating, the discharge valves for the materials open, and the materials fall into the weighing hopper. The PLC calculates the weight of the materials in real time based on the weighing sensors at the bottom of the weighing hopper and the detected weight. When the weight of the materials reaches the preset value, the discharge valve for the materials closes, while another discharge valve opens. The PLC continuously calculates the weight of the materials. When the weight of the other material reaches the preset value, the other discharge valve closes, and the next material discharge valve opens to discharge the materials. This process repeats multiple times. When all the raw materials reach the set weight, the total discharge valve of the weighing hopper opens, and the raw materials fall into the mixer. While the raw materials are falling into the mixer, the mixer starts to stir. When all the raw materials in the weighing container have fallen into the mixer, the total discharge valve of the weighing hopper closes, and the mixer continues to work for a while. Once the raw materials are evenly mixed, the discharge valve of the mixer opens, and the raw materials enter the next process. 

The mixed weighing system is mainly composed of a feeder, a hopper scale, an auxiliary funnel, a feeding bin, etc. Depending on the model of the mixed weighing system, there are multiple weighing hoppers. Each hopper scale is equipped with a weighing module on its side, and there is an auxiliary funnel corresponding to each one below, used to store the materials of the selected hopper scales that were not selected in this working cycle. During the next working cycle, the auxiliary funnel directly participates in the overall calculation. It is worth noting that the appearance of the auxiliary funnel provides more options for the combined calculation, improving the accuracy and speed of the system, thereby improving the efficiency of the entire system to a certain extent. The hopper scale needs to select operating parameters, including the number of hoppers selected for the combined calculation, the target weight of the product, the product accuracy, etc. Start the hopper scale, the materials pass through the feeding chute and are transported to the hopper scale by the radial feeder. The weighing module obtains the weight value of the materials in the hopper scale. After the system performs combined calculation based on the set values of the operating parameters, it obtains the combined result within the range of the product target weight, and marks the selected hopper. If a hopper scale or an auxiliary funnel is selected, the product of that hopper is released to the discharge bin and sent to the mixer for batching. If the hopper scale is not selected and its corresponding auxiliary funnel is empty, the materials of the hopper scale are released to the auxiliary funnel below. Otherwise, the materials of the hopper scale are retained. During the next working cycle, this hopper does not need to add materials and directly participates in the combined calculation. This process repeats until batching stops.
