The sandwich panel line decoiler machine is a special equipment for metal sheet leveling. It is used for leveling steel plates and uneven sheets. It can be composed of uncoiler, leveling, shearing production lines and other sheet product production lines according to relevant configurations. Suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries. The sandwich panel production line includes upper and lower uncoilers. Each uncoiler consists of an uncoiler, a feeding trolley, and a hydraulic station. The decoiler machiner adopts a hydraulic cantilever tensioning type, which is mainly used for steel coil feeding and recycling.

Decoiler Machine

Sandwich Panel Production Line is mainly composed of uncoiling system, lamination cutting, forming machine system (with edge trimming device), steel plate preheating furnace, high pressure foaming system, double crawler, double crawler heating system, band saw cutting system, automatic palletizer and other equipment.. Polyurethane sandwich panel is widely used in metallurgy, petroleum, automobile, mineral processing, water conservancy and other aspects of materials, with strong elastic strength, excellent wear resistance and other advantages.

PU Sandwich Panel Production Line Features

Sandwich Panel Machine Features

1. Sandwich panel machine can product beautiful sandwich panels with high practicality, such as insulation, sound – proofing and flame retardance.

2. Hot air circulation furnace strictly controls pu foaming and solidification temperature in suitable range.

3. Precise measurement, high stability, little dust making of the high pressure foaming system protect worker’s health from harm in producing.

4. The pu sandwich panel machine using 141B(or cyclopentane), instead of CFC as vesicant, PU foaming treatment becomes an enviroment-friendly production technology.

5. Special double belt conveyor design ensures flat surface, even thickness and anti-deformation of panels.

6. PU sandwich panel machine user-friendly design and simple operation control system: HMI together with PLC computer.
