4.Steel plate pre-heating system

Air was heeted by heating device,and came into pre-heating house to heat the upper &

under sheets and strengthen the adhesion between steel sheet & PU foam..The data

that  has been detected by infrared detector would be feedbackedto PLC system .And

then ,the PLC system will control the temperature and reduce deviation.It composed

with heating device ,control cabinet,tempretrue measuring system,pre-heating house,

steel plate conveyer,etc.

5.PU foaming machine

It adopted high pressure pump,have the temperature control system and material

monitoring system.Besides ,could use high-pressure water to clean the mixing-head

without demounting,very convenient.

Features:

1.Through instrument digital display ,to realize monitor during the entire whole course
2.With the PLC controlling system and touch scream ,the operation is more convenience .
3.Using the Germany imported metering pump to make the metering more accurate.
4.Provide two sets of independent high pressure self-clean mixing spray-head , and realize

the online replacement and the maintenance.
5.The mixing spray-head is controlled by servo motor ,the spraying place and moving spraying

is adjustable .

6.Double-belt machine

Double belt conveyor is mainly used for foaming, hardening and ripening and shaping

of core material of sandwich panel being laminated.

Features:

1.Total length of the machine is 36 meters, compared with present production line; the

productivity of the new one is increased 20%.
2.Durable: the belt plates are made with heat treated alloy steel.
3.SIMENS servo motor and the speed reducer made in Italy will be used together to

control the speed and the foaming time to guarantee the quality of the panels.
4.Fast conversion: Hanging type side sealing system with a separate chain could be

converted by one person only; width and thickness could be adjusted .

5.Convenient control: side seal system could be controlled conveniently as the space

between the sealing system and belt plates is reasonable enough to be accessed.
6.The lifting hydraulic cylinder of Double-belt laminating machine is equipped with

synchroniaed valve to ensure the lifting of the upper belt is at the same level and the

frame of the machine won’t be deformed.
