The weighing feeding machine integrates multiple equipment such as storage, conveying, weighing and batching, dust removal, and material mixing. According to the production process requirements and specific material characteristics, it reasonably selects weighing methods such as "addition method" or "subtraction method", and has multiple working modes including single-bucket single-material, single-bucket multi-material, and multi-bucket multi-material. Control can be carried out in the forms of PLC, human-machine interface, single-chip microcomputer, industrial control computer, etc. A reasonable on-site layout and planning design can be configured according to the user's production volume and workshop environment.

The weighing Feeding machine uses a weighing module in the raw material weighing bin to detect the weight of the items to be weighed, and transmits the weight data to the computer for processing. The Weighing system is generally equipped with a digital display screen, which can directly show the current weight value being weighed. When the weight value stabilizes, the accurate weighing value will also be displayed on the screen It is convenient for the operators to inspect the weighing situation. The Electronic scale is controlled by electronic components to complete the automatic weighing process, and it can also exchange various information with other equipment to ensure the smooth operation of the entire automatic Batching system.
The main components of the weighing control system include: weighing silo, weighing sensor, spiral gate at the bottom of the silo, feeding machine, gas pressure equalizing device, air locking device and electrical control part. This weighing hopper is supported by three Weighing modules and is in a suspended state. The feeding machine is installed beneath the weighing silo, and its weight is included in the original weight of the warehouse. After the materials enter the pre-feeding bin, the pre-feeding motor starts to rotate, enabling the materials to enter the weighing and feeding machine smoothly and evenly. The weighing module converts the weight signal of the material into an electrical signal, which is then amplified by the amplifier and enters the PLC for collection and processing. After conversion, the weighing feeding machine will convert another signal into a pulse frequency, and then the frequency converter will convert the speed. Finally, it will enter the PLC for collection and processing. The PLC performs operation processing based on the two collected signals, and then conducts PID operation according to the given flow comparison, outputting control quantities to control the frequency converter of the feeding scale and the pre-feeding frequency converter. By changing the speed of the motor, the system can be dynamically maintained at the given flow rate, achieving stable operation.
