(a) shuttle positioning.

1: bad shuttle.

(1) the loosening of the main bolts in the shuttle throwing mechanism.

Elimination methods: to strengthen the maintenance and overhaul of the circuit, the thickening gasket. Add spring washer lock nut etc.. (2) improper installation or abrasion of the shuttle mechanism. Elimination method: the shuttle rod should be centered in the reed seat. Worn or cracked side plates with skins must be replaced. The use of the nose of the nose. When the skin is replaced, a thin layer of grease or wax can be applied to the contact between the shuttle rod and the leather knot.

2: buffer device adverse effect.

(1) the leather ring is not caused by the bad state of the shuttle, shuttle force is caused by the shuttle and shuttle.

Elimination method:

A: the control of the skin to come and go, usually with the shuttle rod in the box on the back and forth reciprocating motion to 34.9mm-41.3mm, and at the same time adjust the buffer belt movement.

B: use the buffer can wipe the leather ring with a tarp on the surface of the leather ring in the cradle of flexible role.

C: the new skin ring when used on the machine because of the small elongation, buffer belt movement to be adjusted accordingly, to a lesser extent.

D: in high speed and wide width loom, the bolt of the fastening ring frame on the reed can be changed to metal bolt.

E: the width of the skin to be changed from 40mm to 45mm-50mm, it is necessary to reduce the elongation of the leather ring and loose ring rack.

(2) the installation specification of the three wheel buffer device is not correct. Elimination method: to make the three buffer should be in the shuttle rod back contact. The picking stick by the shuttle after the collision, can move outward, interact with the leather ring at the same time, the convex mouth and feet spring buffer disc protruding mouth distance of about 9mm-12.5mm; when the shuttle cast after the spring plate returns to its original position, two convex mouth should be gently connected, such as too tight or too loose, should be adjusted spring. The top of the side plate is about 12mm-13mm away from the eccentric disk, and the length of the buffer belt can be adjusted if the specification is out of specification. 3: two side shuttle box installation bad.

Elimination method: A: shuttle box inside a shuttle correction width 3.2mm, width 1.6mm is outside the shuttle.

B: the size of the shuttle iron convex, the inside should be lower than the shuttle box backplane 0.8mm, the outer side should be more prominent than the back of the shuttle box 3mm-4mm. The spindle and the bottom of the shuttle box are 86.5 degrees.

C: Shuttle iron spring stretch elastic, the shuttle in the shuttle box can be pushed by hand.

II: the common causes of the four types of weft shrinkage

A: causes of formation

1: kink

(1) the weft yarn is easy to twist and bend at the shuttle side.

(2): change the shuttle state to make transverse vibration of the weft crimp kink.

(3): weft by full pipe unwinding to air traffic control, the tension by increasing, the filling cavity ring spindle throw corresponding changes in opportunity.

(4): shuttle shuttle shuttle box side, because the filling itself low moisture regain, twist instability, shuttle guide eye to a very loose selvage yarn, when the shuttle began to move, weft kinks.

2: warp has been due to the weaving weft opening process, the time of the shuttle with improper.

3: a square shape of a square shape of weft weft poplin fabric is more prominent in the. A mainly woven poplin fabric, the opening process caused by a single shedleveling tread plate when four heald frames.

4: the dispersion of the weft is mainly caused by poor hoist.

B: elimination method

1: according to the characteristics of the kink weft, weft to take wet, increase the tension, adjusting weft insertion time.

2: according to the distribution of the region has been the distribution of weft weft and the rules of the production process to adjust the opening, 1, 2 heald frame using the early opening, the 3, 4 heald frame with late openings.

3: the cylinder cloth warp weft shrinkage has been appropriate to take the following measures.

(1) requirements for the quality of raw and semi-finished products.

A: twist small original yarn as weft yarn, cotton should be smaller and less complex, less hairiness, yarn body is smooth, not easy to warp weft with Suodaonei leads to the shrinkage caused by live.

B: in order to improve the clarity of the fabric, reduce the broken ends in weaving, warp sizing rate should be higher.

(2) the weaving process parameters are selected reasonably; the cylinder cloth is woven on the loom of type 1511 or type 1515.

4: a method of eliminating the square shaped weft shrinkage can be taken from the warp and weft two aspects simultaneously.

(1): to: high density of warp and warp opening adjacent cross is separated (high density poplin fabric) opening time, from one to two times of shedleveling shedleveling. The specification of the hoist master the principle of small double opening. Thus, the mutual friction between the warp yarns can be reduced, and the opening definition can be increased.

(2): zonal: without affecting the weft, broken thin defect increased under the premise, appropriate to increase the weft tension, compressed air ring, reducing weft loop phenomenon.

(3) at the same time, in order to further improve the definition of the opening of weaving, we can also adopt measures to increase the tension of the fabric.

5: the method of eliminating and repairing the dispersed Weft Defects in the daily production of dispersive weft is basically the same as the method of solving the problem of star jump and yarn sinking. Focus on the following methods:

(1): hoist the archway as far as possible. When the loom is in normal operation, the front end of the heald frame should not touch the reed cap. Requires not to sway the heald frame.

(2) clear shuttle mouth. Crane should not be too low, in particular, the double disc opening mechanism to meet the requirements of a small double layer openings.

(3) in order to prevent the upper pressure of the reed cap, the height of the reed can be 120.7mm.

(4) the use of nylon sling belts prevents elongation.

(5): picking buffer mechanism maintenance should meet the requirements, pay attention to buffer strength and not normal shuttle rebound phenomenon.

Square eye phenomenon

Plain woven fabric surface presents a network pinhole phenomenon known as square eye.

A: causes of formation

1: the position is too low.

After the opening, the tension difference between the upper and the lower layers of the warp yarn is too small, and when the weft yarn is contracted, the warp yarn is not easy to move transversely with the weft yarn, so the space of the reed teeth after the beating can not be compensated.

2: the left level difference on both sides of the warp, the tension side of the cloth full affected, resulting in a square hole.

3: menopause frame too close to the mouth. The tension of the shuttle mouth is increased, and the warp yarn is not easy to move and generate the square eye.

4: hanging too high or too low side brace. These two conditions will reduce the difference between the upper and lower warp tension. The cloth surface is easy to produce full width and side square.

5: heald heddle warp in tight, causing difficulties in moving the heddle eye beating, beating beating area increases when the warp tension is not compensation, the warp evenness is destroyed, and the surface of the fabric is thin thin not plump phenomenon, serious side eye formation.

6: heald wire bent stem, resulting in the eye is not on the same horizontal line, part of the bulge will also have a square wire.

7: heald frame at the lower end of the clamp damage or loss, so that the lower warp away from the shuttle plate.

8: warp tension is too large, is equivalent to reduce the upper and lower two layers of warp tension difference.

9: the start of the combination of the brake disc is not close contact with each other, in the weaving gap clearance, in particular, when the resistance of the beating, the increase in the slip, weakening the beating force, so that the cloth to produce square eye.

10: improper opening time. When the opening time is early, the weft angle of the warp yarn on the weft yarn is relatively large, and the weft yarn is not easy to back and back after the beating. The opening time is too late, the warp tension is small, and the tension is small at the time of beating up. If the warp is too loose, the cloth will be uneven. In addition, due to the late opening, the upper and lower two layers of warp tension difference is small, the upper layer of the warp yarn is not easy to move sideways, so there will be square eye.

11: stop the contact position of the handle is not standard, the reed hook shaft failure or loose, so that the steel reed beating by the reaction force of the cloth after the occurrence of the weft yarn can not reach the specified position, resulting in square eye.

263自动换纡织布机

B: elimination method

1: in order to eliminate the side eye, the cloth is full and smooth, generally plain fabric back than the chest high beam 19mm-20mm. Heald eye is lower than the average level of 12.7mm, the front of the frame from the chest wall to 210mm is appropriate.

2: hanging heald shoulds not be too tight. The upper and lower layers of the hanging warp are close to the shuttle board. The position of the side strut is lower than that of the chest beam 6.35mm is advisable.

3: reed plate thickness be thinning, or a reed four root to wear two for a reed, square can be improved.

4: good for the body, to ensure adequate and uniform beating force to eliminate the square eye.
