Specification detail of machine
1.Two sets of un-coiler:
It is Automatic and hydraulic, can be used to uncoil steel
coil which is maximal 1300mm's wide, no
more than 8 ton's weighty and steel coiler's inner diameter is
about 500mm.
2.Three 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
rollers.
3.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)
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 one-side 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
machine.
- 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.
Working flow
Coiler loading → adjustable feeding guide → steel panel forming →
steel sheet feeding guide → PU foaming → PU panel conveyor →
