Product Details
Rock Wool/Glass Wool/PU Sandwich Panel Production Line
With Double-Belt Conveyor
Introduction of machine
- A combination production line,wich can produce PU,rock wool,glass
wool sandwich panels,with the function of edge foaming and sealing
for rockwool,glass wool panels.
- High pressure glue spraying unit:glue is sprayed on up and down
steels sheet directly,wich saves glue and insures quality by
maximing the stickness of glue.
- Rotary type:block type,two turning.It is the most advanced and
reliable technology,suitable for producing low density glass wool
panels.

Primary technology parameters of PU sandwich panel product line
- Production Material(mm):(0.25-1.0)×L, yield strength≤G300 Colored
steel
- Production speed:4-8 M/min
- Production type: totally continuous production with PLC controlling
- PU foam thickness: 25-100mm
- Composite structure:position fixed by double rubber tracker

system
Uncoiler roll forming machine
- Excellent groove design and forming technics of roll forming
machine combine with aided design of German copre software which
can release whole stress and reduce waves while roll forming and
keep the final products with planeness.
- Two-side projecting shaft roll former,rollers can be fixed on two
sides shafts.
- Fast vertical loading of roll forming stations
- Roll forming machine on two side can be bidirectional
changed,matched with double-belt conveyor to keep center.
- Width adjusting device by using high-precision ball screw and
linear guide,accuracy tolerance+/-0.5mm.
- Pre-heating room is made of 50mm PU Sandwich panel as fence,which
decreases heat-loss substantially.


PU Sandwich foaming line
- Two sets of conveyor rack: up conveyor is about 24m, down conveyor
is about 30m.They lead the steel sheet from the roll forming
machine to preheating room and to foaming,to cutting.
- One preheating room: It is built by heat-insulation material, and
it could heat up the steel sheet to 25-38 by heater.
- One set of PU two component Liquid mixing and injecting section for
foaming : it adopt Chinese high pressure pump. It have the
temperature control system and material-level monitoring system.
The tank of the material is about 150L. Two tanks.
- Foaming and double rubber device include motor driver system to
make panel.
- The width of belt board is 1250mm, the range of adjusting distance
between upper and lower frame belt board: min 25mm, max 200mm. And
the range of adjusting thickness of sandwich panel
:30mm,50mm,100mm.(30-50 for celling , 50-100 for wall)

Double-belt conveyor
- The double belt adopts two-stage drive (belt plate iis driven by
auxiliary fine-pitch chain),which eliminates the mechanical
nonsynchronous.
- The double belt also is equipped flexible tight system to make the
operation more stable and reliable.
- The width of double belt plate can reach to 267 mm by adopting high
quality special material and elaborate welding heat treatment.
- The side and bottom moulds device of double belt has powerful
functions which can produce the sandwich panels from 20-200mm in
thickness and 600-1240mm in width.
