The automatic traction Batching system directly enters the corresponding weighing controller through the signal of the weighing module, and the weight signal is transmitted to the programmable controller through the serial port or Modbus protocol weighing controller. The programmable controller controls the final control valve of each raw material bin according to the weight of the ingredients, in order to increase the required weight of the raw materials. The S7-200 series adopts 485 bus to achieve communication with configuration, and has functions such as formula setting, ingredient control, ingredient preparation, report printing, remote alarm, etc., realizing remote monitoring. The overall composition of the batching system consists of a host and various slave machines (including virtual hosts) connected by a serial bus. The virtual host and slave machines are also connected by a serial bus, forming a dual bus structure of master-slave microcomputer batching. The host controls the batching through a serial bus, while the virtual host controls the batching through a serial bus after obtaining system control. The host mainly completes functions such as process flow control, real-time display and alarm of working conditions, data storage, report printing, formula optimization, and management consulting. The ingredient system can quickly and accurately complete the quasi dynamic measurement of liquid powder materials, and can simultaneously perform real-time quality testing on multiple liquids and powders. It has functions such as real-time monitoring, data collection, statistics, reporting, printing, etc. for various production links, and can manually or automatically complete the predetermined feeding, frequency conversion mixing, and feeding to finished product tanks, finished product canned barrels, tank trucks, etc. Widely applicable for precise measurement and automatic control of feeding, filling, and pipeline transportation in industries such as mixing.

The weighing module is fixed on the support frame of the weighing batching machine, and the feeding bin is pressed onto the weighing module through a support plate welded to the outer wall of the hopper scale. There is an exhaust cap on one side of the top of the head, and a soft connection port is set in the center of the top of the head. There is an anti arch mixing device installed in the middle of the hopper scale. The anti arch mixing device includes a rotating shaft that runs radially through the bottom of the hopper scale. Oil seals are installed at both ends of the rotating shaft outside the hopper. The outer side of the oil seal is connected to a fixed part through bolts, which is connected to the rotating shaft through bearings. One end of the rotating shaft is connected to a worm gear reducer through a flat key axis, and the worm gear reducer is connected to the output end of an electric motor. There are three arch breaking rods radially connected to the rotating shaft inside the hopper scale after being tightened with nuts. The three arch breaking rods are coplanar, with one on one side and two on the other side. The operation of the ingredient system, the anti arch mixing device is started simultaneously, and the storage tank in the Weighing system automatically drops through the soft connection interface and enters the feeding bin. The weighing sensor real-time converts and transmits the weight data of the feeding bin to the automatic monitoring system in the weighing system for real-time monitoring. When the material level in the feeding bin is at the low limit, open the rotary valve and the storage tank continues to discharge. When the material level in the feeding bin reaches the high limit, close the rotary valve and the storage tank stops discharging. The air in the feeding bin is discharged through the exhaust cap to maintain pressure balance between the feeding bin and the outside world. When the three arch breaking levers of the anti arch mixing device rotate, they can continuously destroy the powder arch formed in the hopper scale or avoid the occurrence of powder arch phenomenon. The material in the feeding bin is conveyed into the conveying pipe of the non pulsating supply device through the discharge port of the hopper scale.

Design features of weighing and batching equipment:

1. The use of continuous dynamic measurement for quantitative measurement of solid and liquid powder materials allows for fast and slow feeding control, which not only improves accuracy but also ensures production efficiency.

2. Using a centralized control console and configuration software development, it can quickly respond to changes in customer needs, with a user-friendly human-machine interface. Operators can monitor the working status of the production line in the control room, improving efficiency and speed in handling abnormal situations;

3. Centralized installation of weighing instruments makes communication with monitoring software and PLC more convenient, safe, and reliable;

4. The production management software has powerful functions and can complete various production formula management, process control, abnormal alarm, and production data collection, storage, report analysis, and printing;

5. Upgrading and expanding is convenient. Users need to expand their existing system by simply introducing the newly installed sensor leads and valve control lines into the control room, and adding corresponding functional modules to the software interface. It is simple and fast.

6. Equipped with pressure and liquid level detection in the tank, liquid level gauges and weighing sensors can be installed in the raw material tank, and the centralized control center can monitor the liquid level, pressure, etc. in real time to avoid accidents.
