The polyurethane sandwich panel production line is a highly integrated system consisting of multiple functional modules working together, each module responsible for critical production functions.

1. Raw material processing system: including unwinding machine, steel plate feeding and docking device, using steel welding frame and pneumatic braking system to ensure smooth unfolding of the coil and maintain constant tension. High end equipment is equipped with hydraulic shearing and laminating devices, which can process various surface materials such as metal decorative panels and aluminum foil.
   

2. Molding and foaming system: The core is the molding machine and foaming machine. The press machine performs various shape treatments on metal coils; The foaming machine is divided into low-pressure continuous or high-pressure types, using an independent variable frequency motor to drive the metering pump and accurately control the mixing ratio of polyols and isocyanates. The mobile fabric machine achieves uniform distribution of foaming materials, with adjustable height and position.
   

3. Laminated curing system: mainly composed of double track machines, usually 18-24 meters in length, equipped with precision hydraulic lifting and insulation units. The chain plate is made of high-quality alloy steel, which has been quenched and ground to ensure smooth operation. The hot air circulation system maintains a process temperature of 60-70 ℃ to accelerate the curing of polyurethane.
   

4. Post processing system: including fixed length sawing machine, trimming device, and automated palletizing equipment. The sawing machine adopts servo drive and achieves precise cutting through photoelectric or marking recognition. Some equipment is equipped with a bag dust removal system to handle cutting dust.

The technical parameters of polyurethane sandwich panel equipment directly affect production capacity and product quality, and different configurations of equipment are suitable for different production needs.

1. Production specifications: The standard production line can handle boards with a width of 400-1220mm and a thickness range of 20-250mm. Specially configured equipment can produce ultra thick boards with a thickness of up to 300mm, meeting the needs of special scenarios such as cold storage.
   

2. Production efficiency: The continuous production line speed of polyurethane sandwich panels is usually 3-8m/min, which is equivalent to a daily output of 1000-2000 square meters (calculated in 8 hours).
   

3. Energy configuration: The total power of the equipment is 120-240KW, of which the heating system accounts for about 50KW. The new equipment adopts insulation design and energy efficiency optimization technology.
   

4. Control accuracy: A control system composed of PLC and touch screen is used, combined with detection switches and frequency converters, to achieve zone control. The metering accuracy of the high-pressure foaming machine can reach ± 1% to ensure uniform foam density.

As a key link in the green building industry chain, the technological progress of polyurethane sandwich panel equipment directly promotes the improvement of building energy efficiency. With the advancement of the "dual carbon" goal, efficient, low consumption, and intelligent new generation equipment will become the mainstream in the market, providing equipment support for global building energy-saving renovation.
