QFA1528 прядильная машина

Main feature: Creel Suspending spindle hangs thick yarns.It can hold the roving in rolling package up to Φ152X406. Draft riple-roller, double apron, swinging racket pressure According to user’s choice, it can be equipped with the stretching and pressure device for any kind of cotton short fibers at present, which includes spring, pneumatics and drafting pendulum arm with V-style, the surface of front and rear roller are helical knurling and rolling pattern on the surface of middle roller. All bottom rollers are made of excellent steel with the technique of surface hardening and chrome plating. Broken-yarn suction Flute tube with a pear shape section and longer inlet is closely mounted to the bottom roller, ensuring high suction rate of yarn breakage and it can also clean the front bottom roller. Each machine with an individual fan. Funnel shape filter is adopted to enlarge filter area. Main driving To drive the main shaft through the high strength flat belt and to drive the spindles through tape drive pulleys of the shaft. The main motor is installed under the suction box at the endstock. Suction fan exhausting is used to take out the generating heat of the main motor. Headstock driving At the head of machine, there is synchronous belt transmission to reduce noises. The change gears of total drafting, twisting and winding are in same size of module, hole, width and can be exchanged with each other. The draft gears are lubricated by oil drops automatically. The head stock gears are lubricated in oil tank. Winding Spindle is damping anti-vibrating type, knee brakes as an option. Snail wire with hard chromium plating has good resistance Aluminum alloy balloon separator. Balloon ring lift independently, which is better to control the spinning tension. Rings can be precisely centered to the spindles. The formation of the cop is suitable for the high speed winding of the automatic bobbin winder. The lifting components of ballon ring and ring railate balanced by the torsion bar. Automaitc control The programs set up controllers to supervise the whole process of yar spinning. Whole body of machine in controlled by transducer on its operation speed, by which it can set up spindle speeds during various sections and spinning length on touchable screen.In the meanwhile, it can also record yarns yield in four shifts as well as demonstrate rotation speed of spindles, line speed of front roller, twister of yarns as well as total stretching times. The spindle speed and run time can be preset on the touchscreen.If doffing before full bobbin is required, pushing the relative button, then the ring rail will wing down and stop at a proper position automatically, whenever the running machine is stopped. Pushing the relative button, the ring rail will reset at the starting position before restarting the machine. Main Techincal Parameter:
