CARDING MACHINE OBJECT AND PARTS DESCRITION

PARTS OF CARDING MACHINE :-

• Chute feed Duct (DFK)direct feed for Carding
• Feed Roller
• Licker-in
• SFL(Stationary Flat Licker-in)
• Cylinder
• Flats
• SFD(Stationary Flat Doffer)
• Doffer
• Delivery trumpet
• Sliver can

OBJECT OF CARDING :-

  
    This is a second process of spinning mill. Here we remove Trash, Neps etc...Straightening the fiber and convert Lap to sliver for further process. Open the cotton tufts individual fibers.

CUTE FEED DUCT :-

    Nowadays all cotton mill having chute feed technology but some old mill using Lap feed (MANUAL FEED). The opened cotton material is dropped from blowroom to chute feed duct with the help of Blowing fan in blowroom. The duct feed the cotton tuft evenly to the card feed roller via feed plate.

FEED ROLLER :-

    Normally Two feed rollers are used in carding. One is opening the cotton it’s placed over the conveyor belt. Another one is used to feed the material to licker-in.

LICKER-IN :-

    Licker-in is a roller having wire point is used to opening cotton and to remove trash lint.

SFL :-

    SFL is placed in cylinder near licker-in. Each SFL having waste plate and knife . SFL waste plate and knife is fitter adjust setting device. If u need to take more trash we adjust waste plate setting close to open. But knife is reversible of waste plate if u need to reduce trash we adjust setting close to open.

CYLINDER AND FLATS :-

    Cylinder and Flats here the major job done in carding they both have wire points rotates opposite direction cotton material travels in between the two parts. Here Nep removal job is done.

SFD :-

    SFD is placed in cylinder near Doffer Each SFD having also waste plate and knife. Waste plate and Knife setting is same as above mentioned SFL.

DOFFER :-

    Doffer take off the fiber from cylinder wires and condense them so that they constitute a coherent web.

DELIVERY TRUMPET :-

    After Doffer web formation created and pass through a delivery trumpet to convert sliver formation. One more work was done on in trumpet measures delivery sliver thickness and variations and give to communication draft control unit. Draft control unit control feed rolls speed deepens upon delivery slivers thickness variation.

SLIVER CAN :-

    Finally the above process done and then we make card sliver to the next process for BREAKER DRAWING.
