[Technical Field]
The present invention relates to a cleaning device for
cleaning a metal frame surface of a spinning nozzle of a spinning
machine.
[Backgroud Art]
In a conventional cleaning device for cleaning the metal
frame surface of the spinning nozzle of a spinning machine
mentioned above, for example, a revolving shaft, a rotating shaft
revolving around the revolving shaft, and a blade for cleaning the
metal frame surface of the spinning nozzle by contacting against
the metal frame surface of the spinning nozzle to the output side
of the rotating shaft, are provided. Moreover, there is a
conventional cleaning device for the metal frame surface of the
spinning nozzle by a rotating-revolving typed blade arranged to
clean the metal frame surface of the spinning nozzle by rotating

The cleaning device for cleaning the metal frame surface
of the spinning nozzle of the spinning machine by the rotating-revolving
typed blade, is constructed to clean the metal frame
surface of the spinning nozzle by revolving and rotating the
blade. Therefore, when cleaning the metal frame surface of the
spinning nozzle without stopping the spinning, there was a problem

yarn gets entangled to the blade instantly when rotating the
blade.
Furthermore, according to the cleaning device for cleaning
the metal frame surface of the spinning nozzle of the spinning
machine by the rotating-revolving typed blade, since the metal
blade which cleans the metal frame surface of the spinning nozzle

spinning nozzle suction means is provided in the downstream side
of the spinning nozzle, the spinning yarn discharging from the
spinning nozzle by the spinning yarn suction means can be sucked
and discharged, the yarn entangling to the blade can be prevented
and a smooth cleaning operation can be carried out.
Furthermore, the cleaning device for the spinning nozzle

spinning yarn can be carried out smoothly. Furthermore, since
the surface of the rough internal surface of the suction pipe
member is coated with heat resisting resin, the drainage of the
silicon oil of extremely high viscosity can be improved, and it
can be acted extremely effective to these points.
