Per Meter Weight Control Gravimetric Feeder For Plastic Pipe Extrusion
Gravimetric Pipe Per Meter Weight Control Machine For Plastic Pipe
1.Introduction
A closed-loop control system -- Gravimetric Feeding Machine,based on weight detection adopts an embedded real-time control system, equipped with high-precision weighing modules, continuously measuring the material consumption of the extruder, and collecting the screw speed and traction machine speed of the extrusion production line in real-time. After setting the meter weight/extrusion amount, based on the set values, the adaptive algorithm is used to adjust the screw speed and traction speed in real-time, thereby achieving real-time control of the pipe wall thickness.
2.Main Components

| Data Acquisition Control Unit | Collecting data of meter weight in any time |
| Screw Speed Acquisition Unit | Adopting the extruder's screw speed |
| Display Control Unit | Inputting and providing changes of data to oprator to check |
| Acquisition Unit for Linear Speed | Adopting the haul off speed |
3.Features
- Adopting production line of extruder for their screw speed
- Adopt embedded real-time control system
- Becoming closed-loop system consisted by extruder and haul off
- Continous measuring the consumption of materials
4.Profits
- Improving the quality of production
- Cut down the consumption of materials
- Shorten the startup time
- Saving materials about 1%-5%
5.Applications
The Gravimetric Dosing Feeder is applicable for plastic film,cables,optical cables etc.
6.Installation
Setting on the extruder with adapter and rack.Adapter and rack also can make by yourselves,after setting on the extruder,putting hopper on Gravimetric System.
