1. The theory of High frequency heating.
High frequency heating is a kind of new heating method. It is also
called Radio frequency dielectric heating. It can form an electric
field with positive and negative pole. The molecules of glue under
high frequency will move in very high speed. The friction among the
molecules will bring high temperature within short time. So it
makes the glue heat themselves. It means high frequency only heat
the glue line but not the whole board.
That is why high frequency machine is very fast and can save the
4x8 feet standard board will take 2-3 mins to finish(including
pressure keeping time). In winter the time will be about 3mins.
2. Brief introduction of HF board joining machine(HF edge gluer)
The system including: High frequency generator, Main press, hydraulic system, control
system, auto feeding and outlet table
The whole cycle of machine is controlled by PLC automatically. The
running cycle is like this:
Feeding cart feed panel into main press-------Mine press plate
down------Side cylinder push------HF heating------Finishing heating
and Pressure keeping-------Side cylinder back------Main press plate
The only thing is to press “START” button, one board will be
finished within short time.
3. The features of the JIYUAN’ s machine:
HF dielectric heating: fast, uniform and safe for the operators.
Automatic feeding and outlet table
PLC automatic control, after wood slats loading, only press “START”
LED fault self-checking system and alarm. Can find the fault and
Instant curing: 1-3minutes for one standard board.
4. The parameter for the whole system:
PLC automatically control, fault self-checking, showing and alarm
