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 → non-stop cutting
