PU/PIR Continuous Sandwich Panel Production Line

Continuous PU Sandwich Production Line, also called polyurethane sandwich
panel manufacturing line machine, is an automatic production line, which is
consisting of decoiler, film coating, pre-cutting, cutting equipment, roll
forming system, preheating, foaming, solidification, band saw cutting, cooling,
stacking and packing. The whole pu sandwich panel line/PIR sandwich panel
production line integrates technologies of mechanics, chemistry, electrical
control, hydraulic pressure pneumatic and temperature control.
Jinggong has been specialized in providing high-quality PIR/PU sandwich panel
production line, feel free to contact us for PIR/PU sandwich panel production

Features of PU/PIR Sandwich Production Line
1.Beautiful and applicable, multiple functions, such as thermal isolation,
sound isolation and flame retardance.
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 stability,
little dust in the locale, protect the worker's health.
4.Using 141B or Pentane as foaming agent. Instead of carbon chloral-fluoride,
make the PU foaming treatment become an environmental production craft.
5.Special double belt conveyor, flat surface of sandwich panel, even thickness,
anti-pattern
6.Operation system controlled by PLC computer, personal design and simple
operation.

Working Process Layout Of PU/PIR/Rockwool Sandwich Panel Production Line
Decoiling System
Decoiler transverse location---Lifting stage move outside---coil hoisting—
lifting stage move inside---Lifting stage rise----Lifting stage car move to
inside position---Decoiler axle expanding (---Pressing-arm press tightly)----
Lifting stage reset position---decoiler uncoiling material
Filming Slitting And Cutting
Filming the plastic film on the panel surface. 
The pre-cutter is used for cutting the single skin panel when it needs to
change to be another profile.
Roll Forming System
There is one set roll forming machine for upper layer profiles. That is double
head roll forming machine.
The upper roll forming machine consists of two sets of forming rollers, one set
of guiding system, one set of the transmission system, one set of frame. 
Rockwool System
The rock wool system consists of rock wool lifting device, rock wool slitting
device rock wool turning device, upper and lower foam spraying system, two
components side sealing foaming machine, dust collecting device and conveyor,
etc.
Pre Heating
Preheat the oven-----Adjust the temperature-----panel forwards-----Send panel
into the oven-----Guiding roller transmission-----Measure the temperature of
panel----Sent panel out of the oven
Foaming Accessories
Accessories of foaming system include sheet transmission conveyor, adhesive
tape sealing device, sponge sealing device.
Double Belts System
DBL is mainly used to overcome the expansibility of foaming and make it solid,
and decide panel thickness and production speed. Side belt is overcome
horizontal expansion and decide the width of panel and guiding to the panels.
Bandsaw Cutting System
Motor power: 5.5kw
Min. Cutting length: 2m (variable according to production speed) 
Motor power for band saw moving: 1.5kw
Max panel thickness: max. 250mm 
Cutting distance: max.1200mm
Total power: 20 kw
Cooling System
The cooling system consists of front and back conveyor, two sets of lifting
belt conveyor, cooling processing conveyor and electric system.
Stacking System
There are sensors equipped on the front conveyor, two panels can be stacked at
the same time if the length is less than 7.5m; one panel can be stacked if the
length is more than 7.5m.
Packing System
It mainly consists of conveyor roller and packing machine.
The wrapping device of packing machine is driven by a reducer motor, adopts
gearwheel and toothed bar driving structure to rotate quickly to cover the film
on the surface of products.
Electrical Control System
Electric system is included in the machines.
