JWF1215 broad width card

Representatives of high production and high efficiency

JWF1209 broad width card is the latest generation of high production card, developed by Sino Machine Group,CHTC QTM, based on the idea of high production, high efficiency, high quality. Benefit from extensive application of hi-tech material and adjustment of card core- carding area, production of JWF 1209 can reach 150kg/hour and sliver delivery speed reach 400m/min.As machine width increase to 1.5m，card sets fit is reduced, so the investment cost such as area occupation, labor, energy consumption can be greatly saved.

Guarantee and measures of high production and high efficiency：

☆　　 More than 60 years card development experience

☆　　 More than 120 thousands card production experience.

☆　　 Advanced processing equipments

☆　　 Width increase to 1.5m

☆　　 Adjust structure of carding area and increase carding area by 74%

☆　　 Extensively apply hi-tech elements

☆　　 Integrated design of card, chute feeder, pre-draft and autoleveller

Carding system with biggest area

Guarantee of efficiently removing neps and trash

☆　　 Working width increase to 1.5m，carding area increase by 50%，greatly enhance production.

☆　　 Adjust the structure of carding system : lift up cylinder and down doffer, increase arc length of carding area to 2.76 m，increased by 74% compared with traditional carding area.

☆　　 Directive feed mechanism can reduce fiber damage. New type of feed plate make cotton feed more clear.

☆　　 Special single licker-in is mounted two mote knife, pre-carding segment around licker-in to efficiently exclude trash and short staple.

Optimized carding elements

Excellent carding efficiency

☆　　 Hi-Tech Al-alloy stationery flat is featured by light weight, stable running, convenient adjustment. It is driven by two tooth belts without need of other fasten part. Therefore it is featured by easy mantling and dismantling, convenient maintenance.

☆　　 Tandem stationery flat, web cleaner and Al-alloy sheet is made by Al-alloy profile, featured by good tip neatness and convenient gauge adjustment to ensure fiber carding more fully and fine.

Modular design：

☆　　 Licker-in section adopts single licker-in and three-licker-in modular design and two noil area can be easily adjusted outside machine. Mote knife under licker-in and clean unit can be used for adjusting noil quantity to reduce fiber loss.

☆　　  Tandem stationery flat, web cleaner, Al-alloy sheet can be configurated and fit in different group according to material, featured by flexible mantling and dismantling, good trash excluding efficiency.

New type of mechanical structure and driving method

☆　　 Step entity frame welded by steel plate, flexible and simple mechanical structure, special machining technology ensure gauges precision.

☆　　 Adoption of multi- independent motor plus vector enhances automation and precision of technological adjustment.

☆　　 Pneumatically controlled turnover cross apron is favorable for observing web.

1 Cylinder：big torque independent motor, motor direct start with stable running.

2 Rotary flat：Independent motor+ vector inverter，stepless speed adjustment，suitable to different material and different technology.

3 Doffer：Independent motor+ vector inverter，stepless speed adjustment，solve the problem of big sliver count fluctuation during acceleration and deceleration.

4Feed：Independent motor+ vector inverter，stepless speed adjustment，levelling system can greatly increase sliver irregularity

New type of chute feeder-JWF1175

☆　　 New type of chute with big capacity supply cotton stably and improve sliver evenness and weight irregularity efficiently.

☆　　 Air is circling inside chute to make batt more even and stable.

☆　　 Feed plate is pressurized by spring so fiber is hold elastically. Distance between feed plate and feed roller is automatically adjusted according to batt thickness.

National initiated pre-draft system-JWF9503

Specially designed for high production card, the pre-draft coiler with drawing technology can greatly increase sliver delivery speed and lay a foundation for heavy sliver count set .

☆　　 3 up and 3 down rollers with guiding roller, double area draft can realize 3 folds draft.

☆　　 Rubber roller is pneumatically pressurized to make pressure even.

☆　　 The whole system is driven by independent motors.

Precise leveling system-FT029

Core of sliver CV

　 FT029 autoleveller is specially used for directive feed mechanism, whose working principle is following: take chute pressure variation to leveling system; control batt status through PID control; detect batt thickness variation by use of precision vertex non-contact sensor to control fiber in short term and detect sliver thickness variation to control fiber in long term, both of them make up of open –close loop control; fit with vector motor to enhance drive precision and ensure sliver CV value.

Long-short term autoleveller

4 Adjust feed roller

5 Feed roller driver

6 Short term control sensor

7 Long term control sensor
