Silk ring spinning frame FK506

main feature :

The Silk ring spinning frame FK506 with an Exact headstock driving system is the foundation for producing high-quality yarn. The headstock is equipped with an open auto-dropping lubrication system and a smoothed driving system. The headstock of FA50 is equipped with a closed circulating bath lubrication system, ensuring cleanliness and sufficient lubrication. The machine adopts the CAPD technology, optimizes the middle frame arrangement, adds spring pieces, ensuring better anti-seismic properties and smooth running. The machine features a high-precision main shaft, stable and reliable driving, and a maximum spindle speed of 25000 rpm. The air channel design is optimized, improving the suction effect, ensuring minimal differential air suction at high speeds. For building can driving motion, a precise worm box is used, eliminating intermittent stopping and ensuring no coil slippage during high-speed winding. The roving creel is made from steel plate, providing a perfect appearance. The machine is equipped with a traveling cleaner, corespandex yarn spinning device, slubby yarn spinning device, and roving traveling device. (Optional) The machine can be equipped with various compact spinning devices. The up-suction and underground-suction options are available at the customer's discretion. The top pulley is made from ABS material, optionally.
