The components of the feeding system mainly include Electronic scale, PLC, small screw, vibrator, touch screen and electromagnetic vibration Feeder. According to the actual production process of each enterprise, the feeding system can calibrate the ratio of various different materials at noon on the touch screen, in this process, the PLC system can read the relevant information of the weight of the material during the operation, and can also discharge and weigh the material according to the electromagnetic vibration feeder started by the program. In addition, when the feeding system starts, the electromagnetic vibration feeder will have a large vibration condition, and the appearance of vibration can facilitate the better and faster discharge operation. And when the material and the calibrated value are closer and closer, the vibration amplitude of the electromagnetic vibration feeder in actual operation can be reduced to a certain extent, and then the fine discharge operation can be effectively realized. When the material reaches the weight value set by the programmer, the discharge process will stop. In addition, in the process of feeding automatic control system operation, whether the implementation of fast or fine feeding can be stepless adjustment of its vibration amplitude, while in the process of weighing the material, the touch screen can display the actual weight of the material in real time, the accuracy of the material weighing can be controlled between ±0.5kg.

The application of spiral motor in the batching control system mainly adopts the frequency conversion multi-speed control mode. In the actual operation process, the operation speed at the highest end is low speed, while the operation speed at the lowest end is still low speed, and the high-speed operation mode is implemented in the middle part. This operation mode can not only reduce the strong impact of the motor in the start and stop process to a certain extent, but also reduce the impact of the motor in the start and stop process. At the same time, it can achieve high-speed operation for the transportation of materials. The braking resistance of frequency converter can avoid the bad situation such as overvoltage protection due to the power generation process of the motor in the spiral rapid downward process to a certain extent. The main mode of operation is to use photoelectric encoder to monitor the specific position and actual speed of the dosing machine in real time.

In the feeding control system, the mixer mainly operates on a preset pipe by feeding the material from the screw into the desired hopper, and then the hopper automatically adds the material to the reactor for batching operations. Under normal circumstances, the pipeline of the mixer will be controlled at the same time, and the control of the phase sequence of the power supply can be operated according to the requirements of the screw transmission forward and backward. This method not only eliminates the need for dragging cables, but also significantly improves the reliability of operation on the basis of reducing the operating cost of the system.

The feeding system is composed of many parts, usually including pipelines, formation switches, automatic control systems and discharging mechanisms, etc., in which the material sensor installed on the hopper can detect the amount of material in the hopper, and the control system can automatically judge the feeding operation according to the test results, while the switch on the mixer pipeline can control the specific position of the feeding. Thus, the automatic operation of the fabric can be realized. The mixer mainly includes bin level detection and control, logical chain and protection control of related equipment, and mixer position detection and control, which can ensure the safe and stable operation of the whole feeding system to a certain extent.
