This PU Sandwich panel production line is an automatic production
line. In the PU sandwich panel producing procedure, the product
line can continuously produce sandwich panel with PU as its core
material. The liquid state raw materials were continuously injected
into the middle of two steel panels and
reacting,foaming,solidifying in the double-rubber belt, the PU
sandwich panel could be cut out automatically according to the
required length for users.
Automatic un-coiler (5 ton)
roll forming machine
PU panel conveyor
Panel automatically cutting system:
Electric control system:
production line layout
chain driven transmission
Coiler loading → adjustable feeding guide → steel panel forming →
steel sheet feeding guide → PU foaming → PU panel conveyor →
1. Two sets of uncoiler
It is Automatic and hydraulic, can be used to uncoil steel coil
which is maximal 1300mm's wide, no more than 5 ton's weight and
steel coiler's inner diameter is about 500mm.
2. Two sets of roll forming machine
Function: Roll forming for the profiles of PU panel
Use the welding H-beam, motor driver, sprocket chain driving
Technical data: Material of roller NO.45forged steel, with digital
controlled procession,plated with hard chrome on surface of forming
3. Pu sandwich foaming line
(1) One preheating room: It is built by heat-insulation material,
and it could heat up the steel sheet to 25-38
(2) 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.
(3) 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
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)
4. Panel automatically cutting system:
Cutting machine can move 2500mm longitudinally along product line;
fly saw of the cutting machine can move transversely 1900mm,
Cutting machine moves longitudinally and
transversely along the slide way.
Cutting machine adopts oneside blade band saw manner, cutting and
revolving after cutting. The cutting
saw can revolve, so cutting in two directions is realizable.
There is panel tight-pressing system (pneumatic) in the cutting
There is location limiter to limit longitudinal and transverse
motion of cutting machine.
5. Electric control system:
The control system adopt the touch screen , PLC , module control
and transducer. The control system adopt Panasonic(JAPAN) product.
There one control platforms and electric trunk by which operating
and controlling the electric motors and all motions (including
hydraulic and pneumatic) in the product line.
Intercalated appropriate amount of portable switch on the product
line, so manual operation get convenient.
Alarm and emergency stop system should be installed in the product
line in case accident happens.
