pu pir continuous sandwich panel production line

Continuous PU / PIR Sandwich Panel Production Line, also called polyurethane sandwich panel manufacturing line/production line/machine, is an automatic production line, which is consisting of decoiler, film coating, pre-cutting, cutting equipment, roll forming system, preheating, foaming, solidification, band saw cutting, cooling, stacking and packing. The whole PU/PIR sandwich panel production line integrates technologies of mechanics, chemistry, electrical control, hydraulic pressure pneumatic and temperature control.

Jinggong is one of the leading sandwich panel machine manufacturers in China who has been specialized in providing high-quality PIR / PU sandwich panel production line. The PU sandwich panel lines were exported to many countries, such as Poland, Brazil, Jordan, Kuwait, Saudi Arabia, Tunisia, and so on. The polyurethane sandwich panel manufacturing line performance has got unanimous approval and favorable comment from domestic and international customers.

Zhejiang Jinggong Science & Technology Co., Ltd., which is located in Shaoxing, Zhejiang, developed the PU sandwich panel production line by themselves. This line has reached the world's advanced technology, stopped relying on import, and entered the time that there is no PU production line manufacturer in China. It means China localization age of PU production line is coming. The pu sandwich panel machine made by Jinggong consists of decoiler, roll forming machine, preheating, high pressure foaming, double belt machine, bandsaw, stacking, packing and cooling, realizing an automatic production from uncoiling to packing. Max production speed is 12 meters per minute. Annual output is 1 million square meters.

Features of PU / PIR Sandwich Production Line

Beautiful and applicable, multiple functions, such as thermal isolation, sound isolation and flame retardance.
Using heated air recycle oven, strictly control the temperature of PU foaming and solidification in suitable range.
Using high-pressure foaming system, precise measurement, high stability, little dust in the locale, protect the worker's health.
Using 141B or Pentane as foaming agent. Instead of carbon chloral-fluoride, make the PU foaming treatment become an environmental production craft.
Special double belt conveyor, flat surface of sandwich panel, even thickness, anti-pattern
Operation system controlled by PLC computer, personal design and simple operation.

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.

Profiles of Polyurethane Continuous Sandwich Panel Production Line

PU sandwich panel is used to make energy saving wall panel, energy saving roof panel, refrigeration house panel, garage door panel, etc. It is a potential building enclosed material with a broad use and a new type of energy saving material advocated by the ministry of construction.
