he new type FA306A drawframe is a new generation drawframe on the basis of the advanced technology of the same products at home and abroad.The curvilinear drafting system of 3over 3with pressure bar is suitable for cotton,cotton type fiber and midfiber and their blend of
2276mm.Ali kinds of slivers processed by this machine can be high quality after the last passage.The gear box of dnving system is in full-enclosed oil bath. Rocking the handle of the drive changing gear in the headstock can adjust draft range,which is convenient and reliable Thenew construction for spring loading is adopted to improve stabilily and reliability .The new construction design of sliver creel is adapted to be nice in appearanced and be regulated according to differenl spining requirements the electric system is controllled by PLC to facilitate maintenance and improve reliabilily of the controling system.tnverter and operators interface panel is optional to make operation easier The stable and reliable automatic can change device greatly reduces labor intensity.
The headstock driving gear box adopts manual gear change structure. The crown and draft gears are all enclosed in oil bath gear box ,suitable for high speeg change drive to adjust the weight deviation of the sliver Outside the box there are two rocking handles and disc counter. Revolve the handle to turn the disc counter,displaying the actual engagement of lhe two sets of gears inside the box The convenlionsl way of aglusting the sliver weight deviation by mounting and dismounting the draft gears has been changeed.Operation is simplified and the number of change gears is reduced.
In addition,a pair of step gears for fixing center~to center distance is fitted outside the box Another 6 pairs of step gears are used for substantial adjustment of stepgears are useg for dubstantial adjustment of the
total draft.The total draft can be 4.013~13.
556 times for the sprinning process requirements
PLC is udeg for electric control for higher reliability of the conlrol system. Inverter is adopted for easy,smooth and stable increase and
reducedn. The operators interface panel is used for shift and length setting, displaying current shift, output of each shift, total output,speed,etc. Fault displaying function is also inslalled for prompt
debugging and machine efficiency
In the headstock gearbox, front tension adjusling mechanism is provigeg between the calenger ang the first roller according fo the
requirement of the new spining process technology, to realize multi~ension adjustment to met the spinning requirements of different matedalsand different products
