sandwich panel machine

PU sandwich panel machine is a specialized equipment used for producing polyurethane sandwich panels. These machines usually integrate advanced foaming technology and automated production lines, which can efficiently and accurately produce polyurethane sandwich panels that meet the requirements.

The working principle of the polyurethane sandwich panel machine mainly involves the steps of mixing, pouring, foaming, and curing the polyurethane solution. Specifically, the polyurethane raw material is fed into the mixing head through a metering pump in a certain proportion for mixing, and then evenly poured onto the bottom surface material of the sandwich panel. Next, the upper layer surface material and the lower layer surface material are transported together to the laminating machine, and foam curing is carried out between the upper and lower chain plates of the laminating machine. After the cured sandwich panel is trimmed on both sides of the production line, it is automatically tracked and cut into the required length by the cutting machine.

The polyurethane sandwich panel machine mainly consists of the following parts:

• Raw material supply system: including polyurethane premix tanks, foaming agent premix tanks, etc., used for storing and supplying chemical raw materials such as polyurethane raw materials and foaming agents.
  

• Mixing head and pouring system: The mixing head is used to mix polyurethane raw material and foaming agent uniformly in a certain proportion, and pour the mixed liquid evenly onto the bottom surface material of the sandwich panel through the pouring system.
  

• Layering machine: used for laminating and shaping sheets, usually using a chain plate transmission structure, with variable frequency and stepless speed adjustment.
  

• Edge trimming and cutting system: After shaping, the board needs to be trimmed by a trimming machine to remove the burrs on both sides, and then cut into the required length of product by an automatic tracking cutting machine.
  

• Hot air circulation system: provides hot air circulation for the production line to ensure temperature control during the polyurethane foaming process.
  

• Electrical control system: Electrical control of the entire production line, including control of actuators such as motors, cylinders, solenoid valves, as well as setting parameters such as pouring time, cleaning time, and blowing time.

FEATURES

• High degree of automation: polyurethane sandwich panel machines usually use PLC human-machine control to achieve automated production, greatly improving production efficiency.
  

• Reliable performance: Key components of the equipment, such as metering pumps, mixing heads, and laminating machines, are made of high-quality materials and undergo strict quality testing to ensure the stability and reliability of the equipment.
  

• Easy to operate: The device's operating interface is simple and clear, and operators only need to undergo simple training to get started.
  

• Easy maintenance: The structural design of the equipment is reasonable, easy to maintain and upkeep, and reduces maintenance costs.

PU sandwich panel machines are widely used in fields such as construction, cold chain, and industrial insulation. Specific application scenarios include:

• In the field of architecture, it is used for steel structure buildings such as roofs and walls of sports halls and industrial plants, as well as insulation systems for residential exterior walls, prefabricated houses and other civil buildings.
  

• Cold chain field: used for insulation wall panels and roofs in environments ranging from -40 ℃ to 120 ℃, such as pharmaceutical cold storage and food freezer.
  

• Industrial insulation field: used for clean room partitions in the electronics and pharmaceutical industries, as well as insulation layers for storage tanks and pipelines.
