Operation Instruction for FH250 Circular Loom

I.

Brief Introduction

FH250 Circular Loom is a kind of hose loom which is optimized and developed on the basis of introducing foreign

similar- equipment and combining with our own experience summarizing from long-term production practice as well.

1,The host regulates speed by variable frequency. It is convenient and flexible for operation, high security, reliability and

high efficiency.

2, Equipped with automatic stop controls breakage of warp yarn and empty weft bobbins and the indication lights show where

the breakage has occurred or if the weft bobbins are empty. This makes the products quality stable and reduces operators

work .

3, Surface of the fabric is even and equal. More than 4 patterns of weave are available .

4,Hose diameter is from 20mm to 110mm and 250mm can be reached by adding accessories .

5,Compact structure and cover smaller area .

II Main Technical Parameters

1)Shuttle speed : 204 rotation/min (Max) 2)Motor: 5.5KW

3)Control power : 220V AC 24V DC

4)Available weave diameter :20mm250mm

5)Available number of warp ends : 478 single ends or double ends .

6)Time of automatic stop : approx. 2/3 rotation

III Installation

We recommend that the Circular Loom should be installed on a 10m2platform of net height approx. 2500mm. By doing

this the equal warp tension is obtained easily and site area of each Loom can be reduced. But it is not objected that

installing the Circular Loom on the same level as the creel . the Loom is required to be horizontally.

IV Adjustment and operation

1,Adjustment: All parts of the Circular Loom have been tested and adjusted when leaving the factory. Customers can use

it directly under normal circumstances except the shuttle gap need certain adjustments during operations, details as

following :

a) Dismantle of shuttle-tang and adjust bolts of bracket 634/3

316


4/16

b) Loosen 613/3 stop screws of eccentric axis of shuttle stop idler

c) Turn eccentric axis with Hex allen wrench and adjust lengthways gap of shuttles to the best state

d) Fasten stop screws

2, Thread: Distributing hose warp yarn which you design to centre of 12 units ,i.e. 478 guiding needles and shuttle bed

evenly .plain weave intervals 2 levels or multiple of 2, twill weave intervals 3 levels or multiple of 3. It neednt interval if

the warp yarn design is 478 pcs . Detailes in and .

3,Traction :lead along the warp yarn upon spring hook and stuck the spring hook in the mouth of warp-stop boardcard ;

clamp warp-stop board ; distribute warp yarn into 4 to 6 shares and tie to the prepared traction head , details in .

Note: Wave circular has been installed . Drive the clutch off the traction equipment and force the shaking arm fan-shaped

gear to occlude with fan-shaped gear of pan axle , Turn handwheel anticlockwise to tighten lead and warp yarn ,exit

handwheel axis and pull off clutch and making it occlude with pan axle.

4, Adjustment of fan-shaped board t: Fix the fan-shaped board on shuttle-tang and make adjustment by adjusting screw of

shuttle-tang.Turn adjusting screw of shuttle-tang when adjusting and it is suitable to adjust fan-shaped board to the

internal edge of waive circular.

5, Adjustment of weft density : According to the weft density of your designed products, exchange the weft gear(E) to the

one meeting requirements ,details in

6,weave by installing weft bobbins: put the weft bobbins finished according to requirements into shuttles . Note: the weft

bobbins should be put the correct place. Insert the weft into the thread hole of fan-shaped board and adjust the head of

shuttles. Press the button after confirmation and make the machine turn slowly ,so that hose will be weaved .

7,Adjustment of weave diameter : After forming fabrics, if there is tolerance between the diameter of fabric and the

required, corresponding adjustments can be made,i.e. turning adjusting screws after loosening locking nuts of shuttle-tang

and adjust corresponding position of fan-shaped board and weave circular ,i.e. daff or furl until satisfaction.

8,Adjustment of distribution disk : the distribution disk must cooperate with guiding needle correctly ,otherwise ,normal

weave is not available . When finding the position is not correct , adjust the distribution disk forward or backward one

case of guiding needle after loosening bolts of distribution disk bracket , then normal weave is available .

V. Lubrication

The lubricated part of the Circular Loom adopt the way of centrifugal splash lubrication .Putting approx.1.5kg of

lubrication into the shuttle-tang and making inspection about it every 2 or 3 months usually or changing the lubrication.

Gear lubrication of good quality is putting into the traction gear box and change it every 6 months . Pay attention to the

lubrication quantity and add it in time when it is lower than the required .

VI Control

There are 3 buttons fixed on the Circular Loom : the green button is for running ,the yellow one is for spot movement and

the red one is for stop. Shuttle speed is regulated directly by variable frequency. The textile workers can control the

rotation speed of shuttles optionally as long as adjusting the knob for shuttle speed on the control cabinet. It is very

convenient to operate. Breakage of warp yarn and weft automatic stop are both to be controlled by low voltage of 24 V,

details in circuit diagram.

VII. Common Faults and exclusion

Common faults reasons exclusion measures

Skipping stitch , unevenly

distribution of thread disk

the head of guiding shuttle or the position of

thread take-up lever is not correct;

distribution disk is too loose or heavy abrasion:

warp yarn spring is off or stuck:

Too much yarn ;

adjust to the best place;

adjust or changing the distribution

Onto spring, check and adjust;

clean out yarn

breakage of warp yarn, fluff warp tension is too much , bobbins is blocked,

shuttle wheel is stuck;

position of needle board is not correct

There is burr on the tension lever of guiding

needle or shuttle.

check and adjust tension, clean out or

change;

check and adjust

check and grind

Not smooth of surface of

fabric

warp ternsion and weft tension is not same ,too

loose or too tight;

lever pressed out by weft bobbins is stuck or

the spring is too loose;

weft is not in the inside of needle board,

floating on the surface;

much time spending on changing weft bobbins;

abrasion of creel support is too big or creel

bearing is stuck;

check and adjust

check and adjust

check and adjust

skilled slowly

check, clean out and adjust

belt is slippery, cant be led

out

roller spring on the traction is too loose;

some gear-key on the traction equipment is

mangled;

check and adjust ;

check and change

distribution disk doesnt work,

breakage of warp yarn,

automatic stop doesnt work,

only can spot move but

running tension

position of distribution disk is not correct;

spring hook is stuck or one of the two pcs of

warp yarn is broken;

spring hook falls on the warf-stopping board;

check and adjust accordingly;

check and adjust or changing spring

hook;

check spring hook and warp tension
