Suitable to open primarily the raw material and feed to next procedure to use in proportion.
Adopts the type of two-hopper open-close, uses the electron weighing system, keeps the same speed with the feeding apron of opening machine.
The diameter of the front and back beater is 310mm and fixed by three nail screw on the surface.
Uses protecting tray to avoid the tangling fiber at the end of the beater’s bearing.
Fine Opener
Opening by card needle plate.
The machine frame is weld by high grade carbon steel with 10mm thickness.
Stress was completely eliminated after quality determined.
The feed-in apron with 880mm width and 4800mm perimeter was made from wood.
There is strong magnet for attracting metal impurities.
There are two feed-in roller lied upper and down.
Both of them with diameter of 70mm and equipped with slot on the surface.
The rollers and input apron are controlled by 0.75kw*4 normal motor and 70/60:1 worm wheel, while the upper roller was pressed by spring.
The diameter of roller in opening machine is 400mm, flange equipped with card needle plate.
High speed centrifugal fan for conveying fiber is a separate fan.
The motors of feed-in and opening roller are chained, while the feed-in has a circle switch.
The motor of fan is 2.2kw*4, the conveying tube with diameter of 200mm plated zinc-iron sheet.
Controlling method: the controlling box is fixed on the side wall of feed-in apron. The feed-in apron and rollers are controlled by the photoelectric which is on the feeding machine, it also has a circle switch.
Machine width: 1000mm
Diameter of roller: 400mm
Speed of conveying apron: ≤10m/min
Output: 100 to 180kg/h
Power: main drive 4kw, feed-in roller 0.75kw, fan 2.2kw, total power 6.95kw.
Feeder
It is suitable to blend the opened fiber in full, and deliver them to next procedure evenly.
The amount of fiber storing is controlled by photoelectric, while the quantity of fibre feeding is controlled by vibrating plate which is adjustable.
The amount of fibre outlet is controlled by photoelectric, the fiber in cotton box transported by spiked apron whose specification is 1370*3800mm.
There is a protection plate at the end of cross section of the beater, which could prevent the fiber entwined.
The beater with diameter of 310mm, whose surface is fixed by three screw.
The machine frame is weld by high grade carbon steel with 8mm thickness.
Stress was completely eliminated after quality determined.
The motor of vibrating is 0.75kw*6 normal motor.
The spiked apron is droved by 1.5kw timing motor and 80/10:1 worm wheel.
Machine width: 1400mm
Production output: 100-180kg/h
Power: 2.25kw
Single Cylinder Double Doffer Carding Machine (Diameter 850)
It is suitable to card compounded chemical fibre such as PET, PP into web.
Cylinder, doffer, working roller, stripping roller all have been qualified determined and precised processed.
Output of doffer is controlled by frequency inverter motor.
Styles and specifications are subject to the finished products.
Fiber is stripped by comb bar.
Material feeding: anti-metal protection device is used at the material entrance of the machine.
Four rollers are muffled metal card clothing up, which are divided into upper and down two groups.
The bearing base of upper roller of the first group and gear wheel of drive are nylon, which could test the metal and has auto-stop warning, gear reversing function.
The main bearing is from a Wuxi brand named “Torrington”.
The main motor of cylinder is timing by inverter.
The fiber feeding by roller is controlled from frequency conversion 0.75kw*4 normal motor and 87:1 cycloid pin gear.
Both cylinder and doffer are castings.
The thickness of cylinder wall is 25mm.
The thickness of doffer wall is 20mm, which added strengthen ring inside.
The other rollers are made from seamless steel with the wall of 6-8mm thickness.
The cylindricity of all the rollers ≤0.05mm to insure the balance of static state and dynamic state.
Cylinder run-out: ≤0.05mm
Cylinder diameter: 850mm
Doffer diameter: 492mm
Working roller diameter: 130mm
Stripping roller diameter: 79mm
Take-in roller diameter: 241mm
Production output: 100 to 120kg/h (based on first grate of 6D chemical fiber)
