Automatically PU Sandwich Panel Production Line 25-150mm Thickness

Automatically PU Sandwich Panel Production Line 25-150mm Thickness

This PU panel line consists of 5 tons automatic de-coiler, chain driven transmission, roll former, PU foaming machine, PU panel conveyor, non-stop cutting device, electric controlling system.

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: 25-150mm

Composite structure:position fixed by double rubber tracker

Foaming system: 

totally automatically continuous foaming, quantity of foaming could be stepless adjustable 

Power of production ≥ 22KW

Total power  ≥ 35 KW

Cutting:pneumatic piston driving, non-stop cutting via sliding table

Electronic controlling system: full-frequency PLC controlling system

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. 

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.
