When the shuttle is flying in the shuttle, the rolling shuttle and the shuttle will be generated due to improper position of the side support and hanging hedge, the steel pen, the improper arc of the shuttle plate, and the poor installation of the shuttle box.
1. Poor installation of the side support position
(1) The side support position is too high, and the shuttle is floating unsteadily with warp yarn, which makes it easy to turn over.
(2) The bolts of the reed seat (K1, K2) are loose, causing the reed seat to sink, and the side support box is 9.5mm higher than the shuttle board, resulting in too large distance between the warp yarn and the shuttle board, which will cause the Rolling shuttle and flying shuttle.
Correction of the side support position should be carried out in conjunction with the upper axis. Check with spacer. For the correct position of the side brace, generally when the curved axis of the plain wet fabric is in the front center, the gap between the side brace and the shuttle plate should be 8.5mm.
2. Poor collar hanging
(1) The height or unevenness of the vortex collar:
1. The collar hanging is too high, the lower warp yarn is very high from the shuttle board, and the shuttle is easy to turn over; the collar hanging is too low, and the opening becomes smaller, When the lower warp yarn is replaced with the upper warp yarn, the opening is unclear, and the shuttle movement is blocked.
2. The hanging collar is uneven and the healing frame is inclined, causing the tension and height of the warp yarn at both ends to be different, which will cause the rolling shuttle and the shuttle.
Elimination method:
Poplin fabric with a single pedal plate is generally o. The gap between the lower warp yarn and the shuttle plate is o. 2mm, that is, the lower warp yarn just floats on the shuttle board; the poplin fabric with double pedal plate is used, and the distance between the lower warp yarn and the shuttle board. The healing frames on the first and second pages are 0.8mm, and the healing frames on the third and fourth pages are 2.4mm.
(2) The installation position of the hanging shaft is not correct; the hanging shaft passes before the helmet, the helmet frame touches the reel cap and the upper warp yarn are pressed down by the wood clamp on the reel cap, causing the helmet frame to move unstable and the warp yarn jump, causing the rolling shuttle and Flying shuttle.
Elimination method:
Installation specifications of poplin fabric hanging shaft. When using a single pedal, the distance between the hanging shaft and the back edge of the top beam is 165mm; when using a double pedal, the hanging shaft supports the feet The distance to the edge behind the top beam is 80mm.
(3) Poor clamping, healing frame and hanging belt:
1. The upper clamping and clamping are broken, the warp yarn is hanging down, the opening is unclear, and the shuttle is blocked from flying; the lower clamping and clamping are broken, and the warp yarn is easy to clamping and clamping is broken, and the warp yarn is easy to clamping and clamping is broken; Floating up. The shuttle moves unsteadily.
2. The healing frame is broken and bent, causing the upper warp yarn to droop and the opening is unclear.
3. The heel belt is too tight. The tension of the warp yarn is too high, making the shed smaller. The shuttle cannot pass smoothly. Causes rolling shuttle and flying shuttle.
3. Loose wear of parts of the opening, feeding and winding
(1) The upper and lower hanging helmet adjustment bolts (M33, M42) are loose, the upper and lower hanging helmet belts (R36, R23) are worn and broken, and the hanging helmet wooden boards (Q16) are broken If the rotor (A5) and pedal disc (E3) are damaged.
(2) The guide leg (C15) of the adjustment rod, the moving connecting rod (C33) of the adjustment rod (C34) is worn, loose, and the pin falls off.
(3) Winding rod (L6), winding up lifting fishing rod square iron (L68) loosens, etc.
AboveAll reasons will cause the fabric surface to not be curled, the shed height will become smaller, and the shuttle will not pass through the shuttle channel smoothly. in addition. The combination of hand delivery and winding is not good, resulting in excessive tension on the fabric surface, which is easy to produce rolling shuttles and flying shuttles.
Elimination method:
Strengthen the maintenance and replacement of the above components to ensure that the shed height meets the requirements. The shed height is corrected with the curved axis at the rear center. The front wall of the shuttle and the upper warp should have a gap of 3-5mm, and the lower warp yarn has a gap of 0.2-1.0mm from the shuttle plate.
When the shed height of the corduroy fabric is turned to the end point of the shuttle rod with a curved axis, the front wall of the shuttle and the upper warp yarn should have 1.6-3.2mm (1/16-1/8 inches) of the front wall of the shuttle and the upper warp yarn. gap. When the semi-bending shaft is in the rear position, the first and second pieces of the lower warp yarn are 0.8mm (1/32 inch), and the third and fourth pieces of the slewing plate are 2.4mm (3/32 inches. inch).
4. The steel reed has an incorrect arc. New reed seats often deform due to changes in temperature and humidity or poor wood quality. The reed seats are damaged after use or the glue quality is poor, which will affect the incorrect arc of the steel reed. If the arc of the steel reed is too small, the shuttle will not fly steadily; if the arc is too large, the friction between the shuttle and the steel reed increases, and both are prone to wear. Causes rolling shuttle and flying shuttle.
Elimination method:
The center of the steel reed should be 4mm higher than the outer edges of both sides of the bottom plate of the shuttle box. At the same time, the widths of the outer end and inner ends of the bottom plate of the shuttle box are also different. When installed on the reed seat, the inner end is more than the outer The end is 1.6mm backward, while the shuttle plate is 0.8mm behind the base plate of the simultaneous box, so the total arc of the steel rake is 4mm.
5. The arc of the shuttle plate (Q2) is too large, too small or in poor condition
(1) The arc of the shuttle plate is too small, causing the shuttle to move unstable; the arc is too large, increasing the friction between the shuttle and the warp yarn.
(2) The shuttle bushing is loose and worn, and the contact area with the shuttle box bottom plate (K14, K15) is not smooth. The shuttle is unsteady in flight.
Elimination method:
The center of the shuttle plate is 4mm lower than the edges of the outer ends on both sides of the bottom plate of the shuttle box. At the same time, the thickness of the outer end and inner end of the bottom plate of the shuttle box is also different. The inner end installed on the reed seat is 2.4mm lower than the outer end, and the total arc of the shuttle board is 4mm. The shuttle board should be cleaned again, or the cardboard cypress should be padded between the crane and the shuttle board to correct.
6. Poor installation of shuttle box back plate (Q3)
(1) The installation position of shuttle box back plate is not straight, the joint between shuttle box back plate and movable back plate is inflexible, and the spring of movable back plate is too tight or too loose. Not close to the bottom plate of the shuttle box, there is cotton dust embedded between the back plate of the shuttle box and the bottom plate of the shuttle box, which widens the inner separation between the shuttle and the front plate of the shuttle box, causing the rolling shuttle and the shuttle,
(2) The angle between the back plate of the shuttle box and the movable back plate (Q4) is greater than the angle of the shuttle, and the upper edge of the distance is cleared out. The shuttle is unstable; if it is smaller than the angle of the shuttle, wavy wear is likely to occur on the back of the shuttle, causing rolling shuttles and flying shuttles.
(3) The Baotou iron or gantry gear of the movable back plate is flush with the movable back plate. When the shuttle enters the shuttle box, the head end of the shuttle collides with the Baotou iron or gantry barrier.The head end of the movable back plate is worn out and the low sinking makes the shuttle unsteady, causing the shuttle to fly and the shuttle to fly.
Elimination method:
(1) Make the inner side of the shuttle box back plate closely connected to the shuttle box bottom plate and in a straight line. The shuttle box back plate and the movable back plate are flexible at the joint of the hinge spring. The spring force of the movable back plate should be moderate.
(2) The angles of the back plate of the shuttle box and the movable back plate should be consistent with the angle of the back plate of the shuttle. Use a spacing block to correct it, and there must be no gaps.
(3) The Baotou iron or gantry gear should Lower than the movable back plate D. 4mm, not flush with each other. The head end of the worn and low-sinked movable back plate should be removed or iron plates should be installed, and small pieces of nitrile should be inserted, or all iron should be made of iron. The gantry stop is replaced with nylon products to reduce the wear of the shuttle and ensure the stable flight of the shuttle.
7. The gantry gear (J31) is bent or incorrect, and the convex surface is protruding. When the shuttle hits the gantry gear protruding point, the flight direction is changed, causing the back of the shuttle to bleed, erased, and the shuttle rolling and shuttles.
Elimination method:
If the gantry gear is bent or the angle is not correct, it should be replaced if damaged, and it cannot be continued.
8. Steel reel installation and poor condition
(1) The height and low position of the steel reel installation is not correct, the steel reel is not completely embedded in the wood, and the steel reel jumps when the shuttle flies. Causes the shuttle to turn over, roll the shuttle and fly shuttle.
(2) The angle of the shuttle steel reed does not match the angle of the shuttle back plate, and the shuttle is unstable, resulting in the rolling shuttle and the shuttle.
(3) The steel reed teeth and steel reed edge iron bars are damaged or protruded, affecting the normal flight of the shuttle and causing the rolling shuttle and the shuttle.
Elimination method;
(1) The lower pendant of the steel pen should be completely embedded under the shuttle board, and the wood should be inserted into the wood to press the center of the pendant.
(2) Check and correct with steel reel angle regulations, and there must be no gaps up and down. Use a removable steel reel adjustment device to adjust the angle, or add or delete the positive angle of the paper cypress pad between the reel cap and the reel foot.
9. The warp yarns are broken, twisted, twisted, or fly, and fall back into the warp yarns, causing the upper and lower layers of warp yarns to be entangled, the shed is not clear, and the running function of the shuttle is blocked, causing the rolling shuttle and the flying shuttle.
10. The bobbin is crooked, the pipe is woven or the weft knot is large, so that the weft yarn is not drawn smoothly, and when the shuttle is thrown out from the switch side. The shuttle deviates from the steel reed due to the weft tension, causing the rolling shuttle and the flying shuttle.
