New Type PU Sandwich Panel Production Line

With Automatically Cutting System

Brief introduction of production line

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 three formed panels and reacting,foaming,solidifying in the double-rubber ,the PU sandwich panel could be cut out automatically according to the required length for users.
This PU panel line consists of 10 tons automatic de-coiler with loading car, chain driven transmission, roll former, PU forming machine, PU panel conveyor, non-stop cutting device, electric controlling system.

Main technology parameters of production

• 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
• 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

Description of 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)

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.

Working flow

Coiler loading → adjustable feeding guide → steel panel forming → steel sheet feeding guide → PU foaming → PU panel conveyor → non-stop cutting
