Rotor Spinning Machine
Some quality of spinning units –
Don’t need any tool for exchanging the spinning components process, the operation is convenience
Compare with other machine, save time for exchanging yarn mass and maintenance
Without separator avoid the fiber wrapping.
Spinning wheels is the important factor for this machine
The highest rotor speed is upto 50000-80000r/min.
Could reduce open end yarn twisting, improve the spinning stability.
A central control system could adjust the air pressure inside rotor spinning.
Reduce the quality requirement for raw material, could be able to rotor spinning special yarn.
All fibers (including high density fiber) could be opened without any defect.
Lightest weight of spinning unit in the world, a maximum reducing for power consumption .
Depend on the different insert plate for adjusting air exhausting, the air flow inside cleaning plate was separated into cleaning air and combing air. The insert plates were equipped with according to different raw material.
Select the special ceramic for new type of navel, extended the service life more 25% than conventional navel; on the other side, reduced the hairness due to the high density and smooth surface of navel.
The high economic benefits of model JWF1609 rotor spinning machine is due largely to the adoption of aluminium rotors ,which prolong the service lives of bearings and reduce the maintenance costs and increase the output.
Improving the Design Continuously For Open end Yarn Process:
The spinning wheels units are improved continuously, the highest rotor speed is risen from 40000rpm( CD 66 rotor), 60000rpm( CD 54 rotor) and 75000rpm( CD 43 rotor), The production is double of the ring spinning system which spinning the coarse yarn.
Open end Yarn Process
A new yarn tension structure and differential roller with three sections make the tension is more tenderness while winding the conical package.
The Drive Side Frame has been designed newly without gear box, which can ensure spinning wheels stability.
The transverse system is step less speed regulated by a stepping motor, which ensures less wearing out for the rubber rolls.
The take-up tension is regulated by step less system, and the draw-off, take-up and transverse systems are separately driven.
The machine is completely controlled by inverters, total 8 inverters, which are easy for adjusting spinning processes.
It is possible to add another processing fan for more stable processing vacuum for the Drive Side Frame in order to ensure the need to spin a special open end yarn.
The guide part is driven by means of rolling pulley, whose force is small. It is helpful for high speed and suitable for long machine.
The motors for combing rollers are separately placed both at Drive Side Frame and Cleaning Side Frame, which ensures that the stress is of uniform.
The bearings are bigger, which is easy for fitting and running and also suitable for long machine.
The gear couplings are longer and applied with nylon gear sleeves, which improve long service life.
The machine can give more productivity and the rotors can be up to 336 heads.
If the machine produces the material with more impurities, both Drive Side Fame and Cleaning Side Frame can have their own impurities fan to ensure a stable vacuum for impurities discharge.
The middle of machine adopts the section-by-section assembling, thus makes the machine assemble and produce very fast. The big package and large gauge save the labor cost and time, thus increased the customer economic benefit. For transportation the package, adopt the conveyer belt which instead of transportation by manual. Thus increased production of open end yarn and saved the labor cost.
The package conveyer motion makes the operator don’ t stop the spinning unit to carry out the doffing operation.
The machine adopts inverter to control motor speed and the timing belt to drive. The adopting of programmable controller (PC) and the convenient spinning parameter adjustment can increase the reliability of the machine and decrease the noise of the machine.
Used the new yarn tension structure and differential roller
