Polyurethane Foam Sandwich Panel Mechanical Equipment

Polyurethane foam sandwich panel machinery is an automatic production line system specially used for the production of polyurethane sandwich panels for buildings. This type of equipment injects polyurethane raw materials between two layers of metal panels, and through processes such as foaming and curing, ultimately forms composite panels with excellent insulation performance. With the continuous improvement of building energy saving requirements, polyurethane foam sandwich panel machinery has become an important equipment in the field of modern building materials production.

Main equipment composition and functions

• Panel pre-processing system
  The panel pre-processing system includes equipment such as uncoiler, leveling machine, cleaning machine, and glue coating machine. The uncoiler is used to unfold metal coils; The leveling machine eliminates the bending deformation of the panel; The cleaning machine removes oil stains and impurities from the surface of the panel; The glue applicator evenly spreads the adhesive on the surface of the panel to ensure the good bonding between the polyurethane foam and the panel.

• Continuous foaming system
  The continuous foaming system is the core part of the production line, consisting of metering pumps, mixing heads, temperature control systems, etc. The high-precision metering pump delivers raw materials such as polyether polyols and isocyanates to the mixing head in proportion, and after thorough mixing, injects them into the cavity between the two layers of panels. The temperature control system ensures that the raw materials react at the optimal temperature.

• Double track laminating machine
  The double track laminating machine consists of two steel belts running synchronously on the upper and lower sides, forming a closed foaming space. The spacing between steel strips can be adjusted to meet the needs of products with different thicknesses. The laminating machine is equipped with a heating system inside to promote the foaming and curing process of polyurethane, while ensuring the flatness of the board.

• Cutting system
  The cutting system includes a horizontal cutting machine and a vertical cutting machine. The horizontal cutting machine performs fixed length cutting according to the preset length; Vertical cutting machines are used for trimming or producing products of specific widths. Modern cutting systems often use numerical control technology, which has the characteristics of high precision and high efficiency.

• Finished product collection system
  The finished product collection system consists of conveyor rollers, stackers, and packers, which automatically collect, stack, and package the boards, reducing manual intervention and improving production efficiency.
