The spiral weighing control system is mainly composed of frame, feed system, data acquisition and processing system, Electronic scale, control system and power system. Electronic scale adopts the weighing module, the working principle is as follows: the weight body will be the mass of the material transferred to the weighing sensor, the weighing sensor will output the signal measurement and processing by the weighing display and controller, and then control the scale body in turn, so as to form a closed-loop measurement and control system to achieve a complete measurement control system.

The Weighing system can test the feeding accuracy and efficiency of the screw feeding device by changing the feeding port size, auger pitch, speed and feeding port size and other parameters for weighing verification, and finally complete the testing of accuracy and efficiency to determine whether the auger meets its working performance, thus laying the foundation for the stability of the equipment. The specific working process of the equipment is as follows: First, the initial value is written into the system; With the change of parameters in the working process, the weighing module is transmitted to the data acquisition and processing system through the communication port, and displayed on the intelligent weighing instrument; Finally, the feeding accuracy and efficiency of the screw Feeder are calculated through the processing system, and the comparative analysis of multiple groups of weighing is carried out to determine whether the screw feeder meets the relevant functional requirements.

Information acquisition and processing system Information acquisition and processing system is the core system of this device. The information acquisition and processing system integrates VB programming technology, weighing instrument technology and sensor technology, etc. By taking the feeding port size, auger pitch, rotation speed and feeding port size as variable factors, one of them is taken as variable factor when collecting weighing data. Other parameters are written to the system as quantifications. The weighing system transmits the actual feeding amount to the processing system through the communication port. Through the timer of this system, the theoretical feeding amount, accuracy and efficiency can be calculated, and then all the information is transmitted to the database, and the weighing data is processed to determine whether the screw feeder meets the relevant functional requirements. By using this system, the accuracy of data acquisition is greatly improved, the influence of human factors is reduced, the reliability of the device is improved, and the working performance of the device is more stable.
