FA320A High Speed Drawing Frame
FA320A high speed drawing frame-the Max delivery speed
is 500m/min.The main motor is controlled by frequency converter.The gear box is
lubricated by sealing oil-immersed type.
Power dissipation is lower.The machine can be controlled by setting date on the displayer
which is communicated to PLC Programmable Logic Controller.
DRAFTING
The drafting system is four over four type(can be became the three type),twin drafring zones with guiding rller and pressure bars.Position
of the pressure bars can be adjusted fore-and-after to suit the ribres of different
kinds and different lengths and enhance the envenness and quality to the sliver.
Being made of acryionitrile butadiene rubber,the roller is vulcanized directly so that
deformation will not happen.It is durable and has a well antireeling feature. The diameter
of all rollers are 34mm,thus resulting in a well exchange ability and convenient management.
Both the top and botton rollers are mounted on meedle bearing which enable a smooth operation
under high speed.The bearing are furnished with oil cups which can be filled up periodically and last
a long time before maintenance.
The draft zones are pressed by swing bridges under the actions of spring which have been
treated with a special processing method,therefore the quality reliable.
GEARING
The gear box is lubricated by sealing oil-immeresed type.All drive gears are high precision bevel gears.
It is resonable driving structure,stable running,low noise and better synchronization.
ELECTRICAL PART
Main motor is double-speed with electricmagnetic-stopper motor.It starts stably and brake quicklly.
Logic controlling is calculated by the import PLC.The PLC is good at anti-interference and it works
reliably.Feeding sliver system is controlled by the micro-computer photoelectric switch to detect
the broken sliver.The photoelectric switch works sensibly,rapidly and reliably.
FEEDING DEVICE
The feeding method is high frame channel type foller active feeding.The creel is made of aluminum
alloy material.It is driven by flat-belt and it works reposefully.
The creel has stable guiding sliver without accumulating waste fiber and resulting in unexpected
drafting.It runs reliably with low noise.There are two types of the creel,one is the height of 1540mm,
the other is 1730mm.The photo-electric self-stopper with inner-amplifier is installed.It is very
sensible and reliable to detect the broken slivers.
