Features
The twist value can be input directly on the function panel,so only drafiing changeable gears qre required. Sliver breakage protection system and constant tension spinning system. Optimization of the design of the front drive and layout, the front layout is simple, good heat dissipation, easy to install and maintain. -Power off flyer auto-orientation,easy to operate. The bridge shunt type wiring,electrical installation convenient reduce electrical signal interference. With flyer intelligent variable speed programble spinning speed is greatly improved. System a key to restore more energy,when the control system software parameters were broken ring, start a key to restore the initial state can be reduced to. Network management can realize long-distance control. Gear transmission is adopted to drive flyer and bobbins,the running speed is more than 1600r/min,transmission smooth,lower noise,high efficiency.
