The working principle of pu sandwich panel machine mainly involves the mixing and foaming process of polyurethane raw material. Specifically, the raw liquid is fed into the mixing head by the metering pump of the infusion machine in a certain proportion, and then evenly poured onto the bottom surface material of the sandwich panel, and transported to the laminating machine together with the upper surface material. Polyurethane foam is foamed and cured between the upper and lower chain plates of the laminating machine. Subsequently, the cured sandwich panel is trimmed on both sides of the production line and cut into the desired length by an automatic tracking cutting machine.

Polyurethane sandwich panel machines typically consist of multiple units, including but not limited to:

• Uncoiler: used for unwinding soft or hard decorative materials.
  

• Clamping damping device: ensures the stability of the material during processing.
  

• Photoelectric correction device: automatically adjusts the material position to ensure processing accuracy.
  

• Preheating device: Preheating the decorative material or bottom substrate, which is beneficial for polyurethane foaming.
  

• Raw material tank supply system: stores and supplies materials required for polyurethane raw materials.
  

• High pressure foaming unit: Mix and foam the polyurethane original solution.
  

• Fabric trolley: used to evenly pour the mixed polyurethane onto the bottom surface material of the sandwich panel.
  

• Laminated conveyor: Transport the poured sandwich panels to the laminating machine for solidification and molding.
  

• Hot air circulation device: Provides hot air circulation to control the temperature on the production line.
  

• Edge trimming machine: Remove the burrs on both sides of the sandwich panel.
  

• Automatic tracking cutting machine: automatically cuts sandwich panels according to the set length.
  

• Electrical control system: Automated control of the entire production process.

The technical parameters of pu sandwich panel machines usually include panel thickness, width, length, production line speed, maximum temperature of hot air circulation, total installed power, etc. These parameters can be adjusted and optimized according to production needs. For example, the thickness range of the board is usually 20-100mm (or wider), the standard board size may be 1200 × 4000mm, and the production line speed can reach 3-20m/min.

PU sandwich panels are widely used in the fields of building energy conservation and industrial insulation due to their excellent insulation, fire resistance, weather resistance, and convenient construction performance. Specifically, the sandwich panels produced by polyurethane sandwich panel machines can be used for:

• Industrial sector: such as insulation wall panels and roofs for cold storage and cold chain logistics; Cleanroom partitions in the electronics and pharmaceutical industries; Insulation layers for chemical and energy facilities, etc.
  

• In the field of architecture, such as roofs and walls of steel structure buildings; Residential exterior wall external insulation system, prefabricated houses, rooftop additional floors, etc.
  

• Special environment: such as the insulation layer of refrigerated trucks and containers; Soundproofing areas in airport terminals, data center rooms, etc.

At present, there are multiple manufacturers in the market that produce polyurethane sandwich panel machines, with a wide variety of product types and specifications. These manufacturers typically provide customized production solutions and technical support to meet the diverse needs of customers. When choosing a polyurethane sandwich panel machine, it is recommended to consider factors such as the manufacturer's strength, product quality, after-sales service, and price comprehensively.

The pu sandwich panel machine is a key equipment for producing polyurethane sandwich panels, with broad application prospects and market demand. When selecting and using, one should fully understand its working principle, main components, technical parameters, and application fields to ensure the production of high-quality products that meet the requirements.
