DISCRIPTION OF M.B.O. :-

MANUFACTURE - LAKSHMI

MODEL - LB3/4 (YEAR 1997)

NO. OF M/C - 1

OBJECT OF M/C :-

• To make homogeneous mixture of different types of fibers.

• Opening & cleaning of the material.

• Mixing & blending of the fibers.

• Removal of dust as a percentage of dust content of the fibers.

M/C PARTS:-

• Feed lattice with conveyer belt,

• Bottom feed lattice with conveyer belt,

• Inclined lattice,

• Stripper roller,

• Evener roller,

• Feed roller,

• Saw tooth beater.

SORTING OBJECT :-

To remove the contamination like hair, colour yarn, jute plastic, polythin, sutli,etc.

PROCEDURE OF SORTING :-

FOR COTTON SORTING {PROCESS} -

1.To hold the cotton in one hand & open the cotton slightly by other hand.

2. Then, to separated the contamination like hair, pouch, sutli, white plasti ,etc in different places.

3. Kept the contamination in different places.

4. And after this procedure count to the register.

This process is done by manually.

No. of worker or sorter required for process= 30-40.

• PROCESS SEQUENCE -

BALE (TO BE SORTED)--M.B.O. (MIXING BALE OPENER)-FIRST SORTING -SECOND SORTING -TUFT IS FED TO BALE PRESS M/C

Sorting load acc. to mixing of cotton fibers-

MIXING A B C D ELOAD 90 60 45 35 30

NOTE:- Sorting load in kg/shift/ sorter.

CALCULATION:- If we have 32 sorter in a shift & work load is 90kgs , then how to calculate the no. of bale.

No. of sorter = 32

Work load = 90kgs/sorter

Wt. of one bale = 170kgs

So, No. of sorter = no. of bale *wt. of one bale /work load

No. of bale = 32*90/170

=17 (approx.)

Break draft =1.34,1.02

Chain wheel –

For lap roll drive , the following different chain wheels are sent –

Chain wheel at coupling = 24/25 T

Chain wheel at lap roller = 77/78/79 T

As per experience , we select the following chain wheels –

For coupling (1) = 25 T

Rear lap roll = 76 T

Front lap roller = 78 T

If the machine is operated with light drafting , the wheels 24 , 76 & 77 are to be used .

Distance between top edge of the saddle top cleaning device shaft =95T

DRAFTING ARRANGEMENT :-

These rows of top roller with synthetics covering are loaded over four rows of bottom fluted rollers. The nipping distance are adjustable between 3& 55mm in the break draft zone so that all the fiber length can be processed & in main zone it is 30 & 54 mm are adjusted .

FORMULA –

Total draft = feed gm/m *doubling/del. gm/m

Draft change gear = total draft / break draft *constant of main draft

SPECIAL FEATURES OF E 65 -

• Latest machine

• 3/3 drafting arrangement

• Better reducing the noil %

• Easy to operate

• Upgraded monitoring display.

COMBING CYCLE IN CASE OF BACKWARD MOVEMENT –

• Detaching

• Nipper move in backward

• Same time feeding

• Gripping

• Combing

In backward movement or feeding system the removal of short fiber are higher as compare to forward feed system .

In comber there are two important index which give improvement in efficiency of machine –

• NOIL INDEX – This index is used to control %age of short fiber in material .

• PIECING INDEX – It is use for maintaining length of cut lap before detaching roller for over lapping.

PRODUCTION CALCULATION :-

PRODUCTION =feed/nip *nip/min*60*8*efficiency*no. of heads*(1-noil%/100)*(1-bett tension/100)/36*840*2.2*wpg.
