Weightlessness metering control system
Product introduction
Weightless metering control system is a set of measurement, calculation, import automatic closed-loop control system, to make up for the material fluctuation in the process of extrusion manufacturing, to achieve the purpose of stabilizing the weight of meters or output. Quanmao weightless metering and control system is easy to operate, constant weight and excellent control precision, is widely used in plastic pipe, profile, cable and film products extrusion processing production line, for the user to save a lot of cost (1%-5%), has brought huge economic benefits.
Scope of application
System principle
Due to the change of raw material density caused by the change of the amount of feed during extrusion, and these changes have a considerable impact on the weight of the rice, so also affect the quality of the product. Manually adjusting the traction speed or extrusion speed can temporarily compensate for these changes, but reduces the stability of the entire extrusion process. Therefore, it is necessary to automatically complete the measurement, calculation and output of each link, closed-loop control to achieve the purpose.
