Steel Structure Sandwich Panel Machine

The steel structure sandwich panel machine (also known as color steel composite panel equipment) is a special industrial equipment for the production of sandwich color steel plates. By combining color coated steel coils with core materials such as rock wool, polyurethane or foam, building panels with thermal insulation, fire prevention and sound insulation properties are made. This device is widely used in construction fields such as prefabricated houses, industrial plants, and cold storage facilities.

By type of core material

• Rock wool sandwich panel equipment: using basalt fiber core material, with a fire rating of Class A, suitable for high temperature environments.
  

• Foam sandwich board equipment: lightweight insulation, low cost.
  

• Polyurethane sandwich panel equipment: High pressure foaming process, combining insulation and high strength characteristics.

Design by Function

• Dual purpose compound machine: It can switch to produce rock wool or foam sandwich board with high flexibility.
  

• Fully automatic assembly line: integrated feeding, gluing, laminating, and cutting modules.

Key structural modules

• Glue coating system
  Equipped with glue storage tanks, sponge application pads, and through-hole spray pipes, the amount of glue is controlled by PLC to ensure uniformity.
  The 304 stainless steel frame has strong corrosion resistance and is suitable for humid environments.

• Squeezing device
  The combination structure of buffer spring and pressure roller, pressure adaptive adjustment, and special surface texture enhance friction.
  High density rubber conveyor rollers to prevent sheet slippage.

• Cutting and collecting unit
  The hydraulic damping buffer frame reduces the plate damage rate to below 0.3% and is equipped with an automatic length setting function.

Technological innovation

• Intelligent control: PLC digital regulation of temperature, pressure, and speed, supporting parameter memory and fault diagnosis.
  

• Wear resistant upgrade: The main conveyor roller is made of composite rubber material, which extends its service life by three times.
  

• Efficient production: Variable frequency stepless speed regulation, completing specification switching in as fast as 6 minutes.
