Corrugated Roofing PU Sandwich Panel Machine for Polyurethane Sandwich Panels

Production Characteristic and Use

This machine is suitable to PU sandwich production, such as wall panel and roofing panel. 

The plate can insulate heat, sound, and prevent burn, widely used in roof panel, wall panel, and so on.

First Stap

Loading material---decoiling---guide--roll forming---cut to length---out table

Second Step

Loading roofing product---pre-heat the steel---foaming---combined two parts---transportation---packing manually

Specification Detail

Item	Description
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.
Three sets of roll forming machine	1. Function: Roll forming for the profiles of PU panel 2. Use the welding H-beam, motor driver, sprocket chain driving 3. Technical data: Material of roller NO.45forged steel, with digital controlled procession,plated with hard chrome on surface of forming rollers
PU sandwich foaming line	1. 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. 2. One preheating room: It is built by heat-insulation material, and it could heat up the steel sheet to 25-38 by heater. 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. 4. Foaming and double rubber device include motor driver system to make panel. 5. 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	1. 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. 2. 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. 3. There is panel tight-pressing system (pneumatic) in the cutting machine. 4. There is location limiter to limit longitudinal and transverse motion of cutting machine.
Electric control system	1. The control system adopt the touch screen , PLC , module control and transducer. The control system adopt Panasonic(JAPAN) product. 2. 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. 3. Intercalated appropriate amount of portable switch on the product line, so manual operation get convenient. 4. Alarm and emergency stop system should be installed in the product line in case accident happens

Introduction of Machine

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 sandwic
