Features:
● Control sysetm and screw freqency coversion drive with same platform software ,it is convenient to control integration with extruder；
● Discharge valve adopts unique gear structure to prevent material blocking, pateneted product；
● All spare parts of the whole series product can be in common use ；
● With two control modes can freely swcith: ‘extrusion output mode ' and ‘ meter weight control mode ；
● With the alarm histroy function；
● With Ethernet communication function, it can realize networking with the molding machine and centralized monitoring function.
Working principle:
Loss in weight Feeder (granules) is generally installed on the top of the plastic extruder to realize the closed loop control of the extruder output(kg/h)：via real-time collect the weighing hopper raw material comsuption which is in unit time of extruder(actual extrusion quantity kg/h) ,and real-time comparison with the extruder setting (target extruder), if there is difference between these, the software of loss in weight feeder will fynamincally adjust the speed of the extruder screw to achieve the exact consistency between the actual and the target extrusion amount；
Furthermore, the loss in weight feeder can also access the ‘line speed m/min' signal of the haul-off unit which at the end of the extruder production line.Through the internal calculations of the softward, that is:(extrusion quantity kg/h）/(linear speed m/min)=pipe weight kg/meter (linear speed can be converted from ‘meter/min' to ‘meter/h', we can get the ‘meter weight' control which is we required；
Control system standard equipped with standrad ethernet interfaces which is facilitate data integration with third-party devices.
