Liquid filling scale is an automatic quantitative measuring equipment, its function is to automatically divide a large number of bulk liquid materials into predetermined weight of small loads for quantitative container packaging. Automatic weighing filling method is adopted. The filling quantity can be adjusted immediately, and the operation is simple. Just put the container on the conveyor chain, and transport the container to the filling station through the conveyor chain, and you can automatically peel and fill. When the filling reaches the set weight, the valve is automatically closed. With automatic peeling function, reduce the workload of workers, improve work efficiency. In addition, the buffer filling method is used (that is, the first fast and then the slow), which solves the overflow of the filling material due to the filling is too full. At the same time, the anti-drip optimization design is carried out for the filling head to make the filling amount more accurate.

The automatic Filling machine is designed and configured with SIMATIC, programming and troubleshooting software. Users can write programs and configure hardware in STEP7, and download user programs and hardware configuration information to the CPU, or upload it from the CPU to the machine. When the program is downloaded and debugged, the PLC system can perform various automatic tasks. The performance of the Filling system already depends not only on the PLC's CPU, but also on the extended environment in which the PLC is located (that is, the network environment). The PROFIBUS network established by the packaging line of the filling system is a control network for SIMATIC at the unit level and field level, applying mixed-media transmission technology and the logical topology of tokens and master-slave, which can be transmitted simultaneously on twisted pair or optical fiber.
