Audited Supplier Loss in weight feeder - weight meter- Online Measurement and Control System of Per-meter Weight
Description and Advantage
1. Suitable for mono and multi-layer extrusion lines for blown film, cast film, sheets, and for the production of tubes, profiles and cables.
2. Reduce the reject rate and lower the cost of reject parts storage
3. To monitor the thickness of extruded products in the whole process
4. To solve the problem of the current fluctuation of the host machine in the process, which cannot be adjusted in time
5. To solve density changes of new raw materials and renewable material, the size and proportion of the crushed material and other issues
6. To solve the problem of waste caused by replacement of different manufacturers of raw materials
7. To solve the problem when the pipe is getting thinner, caused by shortage of material in the tank
8. To solve the problem that the filter is blocked
Application
Figure1:
the material starting-up status. This gravimetric extrusion control system is installed between material storage hopper and extruder throat. It monitors the loss in weight of materials in its weigh chamber . Based on this, to calculate the mass throughput rate of the extruder. In auto control mode, our product- meter weight can control the extruder or the production line speed to maintain a set output or a set product weight per unit length.
Figure 2:
While the material reduces little by little, the system will do the real time measurement of per meter weight and extrusion output continuously.
Figure 3:
When the weight of the material in the weigh chamber falls below a preset value, a side valve will open and refill the cahmber from the material storage hopper. Then a new measurement and control system begin:
