The automatic feeder is equipped with Siemens S series PLC programmable controller and relay, which is responsible for controlling the start and stop of each automatic valve and pump; The weighing instrument starts the tank under the control of the PLC, and the reaction tank outputs different signals (fast, slow, discharge, etc.) to the PLC at different metering stages, which is directly controlled by the PLC to the external equipment.

The automatic Feeder is mainly composed of the upper tank part, the weighing tank part, the weighing tank part, the weighing tank part, the automatic calibration device, the weighing body support, the weighing control system and the computer management system. The upper tank of the scale is composed of a storage tank, a feed gate, a level device, etc. The storage tank is a storage tank used to temporarily store materials while the weighing tank is accumulating and discharging materials. The weighing tank part is composed of weighing tank body, discharge gate, weighing module, etc. This part, together with the weighing control part, constitutes the basic measuring unit of the bulk material scale. The weighing tank is composed of a discharge tank and a material level device. The discharge tank accepts the material of the weighing tank and gradually emptier the material. The automatic calibration device is used to meet the needs of installation and debugging, weighing setting and time checking. The control system is mainly composed of weighing sensor, weighing control cabinet, material level device and other parts, which controls the action of the non-continuous cumulative automatic feeder and is the center of the whole bulk material weigher. The computer management system is installed in the control room, which is responsible for collecting the weight data of the control system, comprehensively monitoring the work of the system, and can program the PLC and modify the weighing control parameters through the window software.
When the weighing tank is empty, close the gate at the weighing tank, clear the weighing tank automatically, and the material transported by the screw machine enters the weighing tank; Feeding process: close the gate at the weighing tank, open the gate at the weighing tank, and the material enters the weighing tank from the weighing tank to the feeding section; Weighing process: When the required weight of each scale is reached, the gate at the tank on the scale is closed for weighing and measuring, and the weight value of the scale is automatically stored and accumulated; Discharge process: After the measurement is completed, the gate at the weighing tank is opened, and the materials are put into the tank by human weighing; Judgment process: When the weighing tank discharge is completed, the gate at the weighing tank is closed, and the weighing tank is automatically cleared to zero and enters the next weighing cycle. During the whole measuring process, there is no gate at the tank under the scale, and the feeding screw of the tank on the scale is always continuously and stably fed. According to the closing and opening of the gate of the weighing tank and weighing tank and the stability time required by the weighing tank, the static measurement is realized and the requirements of continuous transportation are met.
