Automatic sawing PU sandwich panel continuous production line
Polyurethane resin,curing agent,and foaming agent are delivered to
high-speed mixing head in certain proportion through metering
pump,evenly mixed and continuously coat on basal plate by coating
head’s reciprocating motion,then enter into double crawler machine
with plate,foam and cure between the top and bottom layer of heated
double crawler machine;when it is cured and shaped,the trimming
device on both sides will get it into accurate size.Finally,the
sizing following tracing cutting machine cut off it as per preset
length.
Features
1. Beautiful and applicable,multiple functions,such as thermal
isolation,sound isolation and flame retardence.
2. Using heated air recycle oven,strictly control the temperature
of PU foaming and solidification in suitable range.
3. Using high pressure foaming system,precise measurement,high
stabilith,little dust in locale,protect the worker's health.
4. Using 141B Or C5 as foaming agent.Insted of carbon
chloral-fluoride,make the PU foaming treatment treatment become
environmental production crafe.
5. Special double belt cojveyor,flat surface of sandwich panel,even
thinckness,anti-patter n.
6. Operation system controlled by PLC computer,personal design and
simple operation.

Automatic control of pu sandwich panel production line:
Automatic control system includes uncoil area control, double
crawler forming machine and drying cutting area control, the whole
control system is operated through touch screen parameter input and
buttons to realize automation production with reliable and stable
preformance, simple and easy opeartion, Each operating position is
installed with emergency stop button to ensure equipment and
personal safety in case of an emergency, The adopting of new
technology realizes high accuracy, high intelligence, and high
speed control.
Product features of pu sandwich panel production line:
1. Wide application: Ddouble sided color steel tile, one side color
steel, the other side soft material panel, one side soft material
panel, etc.
2. Fully automatic
3. Technology advantage: The whole line is designed by adopting
European technology and developed by our company, can reduce the
cost, and improve the machine strength, accuracy and stability.
4. The electrical control system adopts international advanced
brand, reliable and less malfunction.
