The entire continuous PU sandwich panel production line includes:

The whole PU&Rock Wool sandwich panel production line includes:uncoiler, steel panel lifting device, filming and cutting device, ribbing device, main forming machine, steel panel connecting device, steel panel pre-heat equipment, rock wool system,high pressure foaming machine, side seal device, double-belt conveyor machine, heating device of double-belt conveyor, automatic tracking band-saw, output roller path, panel cooling system, automatic stacker, wrapping machine and so on.


Hydraulic uncoiler: steel coil feeding, recycling

Filming: protect the surface of the steel plate, transport the steel plate, and ensure that the steel plate is pasted without bubbles

Cutting machine cutting edge recycling device: horizontal cutting ends the order to reduce waste (linear guide track cutting), vertical cutting meets the requirements of multiple versions, cutting edge grab is to cut the excess sheet to meet the required width
Up and down pressing equipment: Rolled sandwich panel side connection part and corrugated rib of panel
Forming machine: Rolled panel forming, one of the core equipment
Pre-heating device: Pre-heating drying room, pre-heating the base material, so that the polyurethane foam reaches the best conditions, electric heating method
Polyurethane high-pressure foaming machine: Continuous high-pressure foaming machine system, automatic production line, high continuous injection accuracy, online adjustment of various material ratios
Polyurethane pouring equipment: high precision, flexible adjustment, computer controlled mixture uniform pouring
Double-track laminating machine: The core material of the sandwich panel is foamed in the machine, and it is cured and shaped in the laminated state.
Side seal: conveying sheet
Double track temperature control heating system: track heating, electric heating, oil heating, gas heating, steam heating
Band Saw Cutting Machine: Online fixed length cutting to meet order requirements
Cooling flip system: uniformly dissipate the composite boards to prevent defects caused by uneven heat dissipation immediately after the composite boards are stacked.
Palletizer: complete automatic stacking of composite panels
Packing machine: Plastic-seal packaging of the stacked cost plates, automatic placement of pads, and automatic sealing of both ends. Integrated packaging, good plasticity and high degree of automation
