Operation Process Of Sandwich Panel Machine

The operation details of sandwich panel machines of different models may vary greatly. It is recommended to refer to the specific equipment manual or contact the manufacturer for customized guidance.

Preparation work

• Equipment inspection
  Check whether the power supply, air source, and hydraulic system are normal, and confirm that there is no looseness or oil leakage in each component.
  Verify the specifications and equipment compatibility of the panels (such as color steel plates, rock wool, polyurethane, etc.) to ensure that the core material and panel thickness meet production requirements.
  Clean the conveyor belt and workbench to avoid debris affecting the quality of sheet metal forming.

• Parameter settings
  According to production requirements, input parameters such as board length, width, and thickness on the control panel.
  Adjust the temperature and pressure parameters of the foaming machine (such as setting the foaming temperature at 20-30 ℃ for polyurethane sandwich panels).

Production operation process

• Loading and alignment
  Load the color steel plate coil into the unwinding machine, and use a correction device to ensure that the plate is centered and enters the forming roller pressing section.
  Core materials (rock wool, foam, etc.) are evenly laid on the bottom panel through the automatic paver.

• Forming and Composite
  After the panel is roll formed, it enters the composite section and is bonded with the core material through hot pressing or adhesive bonding (polyurethane sandwich panels require high-pressure foam filling).
  Real time monitoring of composite pressure (usually 0.3-0.5MPa) and temperature (approximately 40-60 ℃ for polyurethane foaming).

• Cutting and Stacking
  After cooling and shaping, the board is precisely cut to the set length by a CNC flying saw.
  The automatic stacker crane stacks finished products in batches, and each layer needs to be padded with isolation film to prevent scratches.

Quality control

• Online detection: Use an infrared thickness gauge to monitor the uniformity of the plate thickness. If the deviation exceeds ± 0.5mm, the machine needs to be stopped for adjustment.
  

• Sampling test: 1-2 finished products are sampled per hour to test their fire resistance (such as rock wool sandwich panels that meet Class A fire standards) and compressive strength.

Shutdown and maintenance

• Daily maintenance
  Clean up residual foam or glue after turning off the power, lubricate moving parts such as chains and bearings.
  Check the hydraulic oil level and replace the filter regularly (it is recommended to replace it every 500 hours).

• Fault handling
  If the board deviates, immediately activate the emergency stop button, adjust the correction device or check the parallelism of the roller shaft.
  When foaming unevenly, it is necessary to check whether the mixing head is blocked or whether the raw material ratio is accurate.

Safety precautions

• Operators should wear protective gloves and goggles to avoid contact with high-temperature components or chemical adhesives.
  

• It is strictly prohibited to manually adjust the equipment during operation, and it is necessary to hang and lock it during maintenance.
