The weighing supply and distribution system is mainly composed of the upper part of the scale, the hopper weighing part, the lower part of the scale, the automatic calibration device, the scale body support, the weighing control system and the computer management system. The upper bucket part of the scale is composed of storage hopper, feed gate, material level device, etc. The storage hopper is a hopper used to temporarily store materials when the hopper is accumulating and discharging materials. The weighing part of the hopper is composed of the hopper weighing body, the discharge gate, the weighing module, etc. This part, together with the weighing control part, constitutes the basic measuring unit of the bulk material scale. The weighing hopper is composed of a discharge hopper and a material level device. The discharge hopper accepts the material weighed by the hopper 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 batching control system is mainly composed of weighing module, weighing control cabinet, material level device and other parts, which controls the action of non-continuous accumulation automatic hopper scale, and is the center of the whole bulk material scale measurement. 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.

Judgment process: When the hopper is called empty, close the smell door of the hopper on the scale, automatically clear the hopper, and the delivered material enters the scale hopper; Feeding process: close the gate at the hopper weighing, open the smell door at the weigher bucket, and the material enters the hopper weighing by the weigher bucket and enters the feeding section; Weighing process: When the required weight of each scale is reached, close the smell door of the bucket on the scale for weighing and measuring, and automatically store and add the weight value of the scale: discharge process; After the measurement is completed, the smell door of the hopper weighing place is opened, and the material is lined up under the hopper; Judgment process: When the hopper scale is finished, the gate at the hopper scale is closed, and the hopper scale is automatically cleared to zero and enters the next weighing cycle. During the whole measuring process, there is no gate at the bottom of the weighing bucket, and the feeding screw of the weighing bucket is always continuously and steadily fed to the screw, and the feeding screw of the weighing bucket is always continuously and steadily running. According to the closing and opening of the gate of the bucket and hopper on the scale and the stable time required by the hopper weighing, the static measurement is realized and the continuous transmission is met.

It is mainly composed of the upper hopper part, the hopper weighing part, the lower hopper part, the automatic scale calibration device, the scale support, the weighing control system and the computer management system. A weighing control system and a computer management system, the upper hopper of the scale is composed of a storage hopper, a feed gate and a material level device. A storage hopper is a hopper used to temporarily store material while the hopper is weighed, for stacking and unloading. The weighing part of the hopper is composed of the hopper weighing body, the unloading gate and the weighing module. This part, together with the weighing control part, constitutes the basic unit of measurement of the bulk material scale. The lower hopper of the scale is composed of a discharge hopper and a material level device. The discharge hopper receives the material weighed by the hopper and gradually empters the material. The automatic scale calibration device is used to meet the needs of installation and commissioning, weighing setting and normal calibration. The batching control system is mainly composed of weighing module, weighing control cabinet and material level meter, which controls the action of non-continuous pile automatic hopper scale and is the center of the whole bulk scale measurement. The computer management system is installed in the control room, responsible for collecting the weight data of the control system, comprehensively monitoring the work of the system, and programming the PLC through the window software and modifying the weighing control parameters.

The batching control system is mainly composed of weighing module, weighing control cabinet and material level meter, which controls the action of non-continuous pile automatic hopper scale and is the center of the whole bulk scale measurement. The computer management system is installed in the control room and is responsible for collecting the weight data of the control system and comprehensively monitoring the work of the system. The PLC is programmed, and the weighing control parameters are modified through the judging process of the window software. When the hopper is empty, the odor door at the upper hopper of the scale is closed, the hopper is automatically reset, and the material delivered by the screw machine enters the upper hopper of the scale. During the feeding process, close the weighing door of the hopper, open the odor door at the hopper on the scale, and the material will enter the hopper scale from the hopper on the scale and enter the charging section; Weighing process When each scale reaches the required weight, the loading hopper door of the scale is closed for weighing and measuring, and the weight value of the scale is automatically stored and the discharge process is accumulated; After the measurement is completed, open the door at the weighing part of the hopper, and the material is discharged into the hopper by the scale; Judgment process: After the end of the hopper weighing, the gate at the hopper weighing is closed, the hopper weighing automatically returns to zero, and the whole measurement process enters the next weighing cycle. The lower hopper of the scale has no gate, and the belt conveyor is connected with: Stable feeding, the feed screw on the upper hopper of the scale also continues to operate stably according to the closing and opening of the gate on the scale and the stability time required for the hopper to weigh, which can achieve static metering and meet the requirements of continuous transportation.
