Features of PU/PIR Sandwich Production Line

1. Beautiful and applicable, multiple functions, such as thermal isolation, sound isolation and flame retardance.

2. Using heated air recycle oven, strictly control the temperature of PU foaming and solidification in suitable range.

3. Using high-pressure foaming system, precise measurement, high stability, little dust in the locale, protect the worker's health.

4. Using 141B or Pentane as foaming agent. Instead of carbon chloral-fluoride, make the PU foaming treatment become an environmental production craft.

5. Special double belt conveyor, flat surface of sandwich panel, even thickness, anti-pattern

6. Operation system controlled by PLC computer, personal design and simple operation.

Working Process Layout Of PU/PIR/Rockwool Sandwich Panel Production Line

Decoiling System

Decoiler transverse location---Lifting stage move outside---coil hoisting—lifting stage move inside---Lifting stage rise----Lifting stage car move to inside position---Decoiler axle expanding (---Pressing-arm press tightly)----Lifting stage reset position---decoiler uncoiling material

Filming Slitting And Cutting

Filming the plastic film on the panel surface. 

The pre-cutter is used for cutting the single skin panel when it needs to change to be another profile.

Roll Forming System

There is one set roll forming machine for upper layer profiles. That is double head roll forming machine.

The upper roll forming machine consists of two sets of forming rollers, one set of guiding system, one set of the transmission system, one set of frame. 

Rockwool System

The rock wool system consists of rock wool lifting device, rock wool slitting device rock wool turning device, upper and lower foam spraying system, two components side sealing foaming machine, dust collecting device and conveyor, etc.

Pre Heating

Preheat the oven-----Adjust the temperature-----panel forwards-----Send panel into the oven-----Guiding roller transmission-----Measure the temperature of panel----Sent panel out of the oven

Foaming Accessories

Accessories of foaming system include sheet transmission conveyor, adhesive tape sealing device, sponge sealing device.

Double Belts System

DBL is mainly used to overcome the expansibility of foaming and make it solid, and decide panel thickness and production speed. Side belt is overcome horizontal expansion and decide the width of panel and guiding to the panels.

Bandsaw Cutting System

Motor power: 5.5kw

Min. Cutting length: 2m (variable according to production speed) 

Motor power for band saw moving: 1.5kw

Max panel thickness: max. 250mm 

Cutting distance: max.1200mm

Total power: 20 kw

Cooling System

The cooling system consists of front and back conveyor, two sets of lifting belt conveyor, cooling processing conveyor and electric system.

Stacking System

There are sensors equipped on the front conveyor, two panels can be stacked at the same time if the length is less than 7.5m; one panel can be stacked if the length is more than 7.5m.

Packing System

It mainly consists of conveyor roller and packing machine.

The wrapping device of packing machine is driven by a reducer motor, adopts gearwheel and toothed bar driving structure to rotate quickly to cover the film on the surface of products.

Electrical Control System

Electric system is included in the machines.
