How To Deal With The Breakdown Of The Bending Needle And Machine Needle Of The Sewing Machine

Broken bending needle

1.

The expenditure of the upper bending needle is large, and the broken needle is broken when the height is too low: the new bending needle is adjusted according to the standard.

2. The upper and lower bending needles, chain line Crochet screws, loose needles: replace the new bending needles, and install them according to the standard.

3. The position of the lower bending needle is not correct: adjust the new needle according to the standard.

Breaking up and bending needles

1. The thread of the sewing thread is wrong or bent upward. The pressure of the clamp wire plate is too high: the thread should be properly threaded or the needle nut should be unscrewed.

2. The upper curved needle eye hair: apply the polishing paste on the line and wear the upper curved needle to pull the light.

Broken bent needle

1, the thread of the sewing thread is wrong or under the pressure of the needle clamp wire board is too large: properly thread or screw down the needle thread clamp nut.

2. The lower bending needle touches the small needle plate, causing breakage: grinding the small needle plate, lowering the lower needle height according to the requirements.

3. Lower curved needle eye hair: apply string polish to the polishing paste and penetrate into the lower curved needle eye to smooth Konra.

Chain thread hook and needle thread

1, the thread is worn wrong or the thread is not smooth: thread is removed to smooth the thread as required.

2, giving cloth teeth have front mouth: grinding or polishing front mouth.

3, there is a scar on the tip of the needle: replace the new needle.

4, take-up cam has a scar: grinding, polishing thread pick cam.

5. Improper position of the take-up cam: adjust the position of the take-up cam.

Chain stitch machine needle and thread

1, machine needle and chain line Crochet positioning is not allowed: re adjust its position.

2, chain line machine needle clamp plate pressure too tight: loose chain machine needle thread clamp nut.

3. The distance between the needle and the needle is too large: unscrewing the chain screw, locating the screw, and turning the chain thread hook to close the needle.

4, machine needle bending or needle tip hair, switch machine needle.

5, the direction of the machine needle slot is not correct: adjust the direction of the needle slot, so that the machine needle slot can be directed to the operator.

6, the chain line crochet needle blunt: repair the chain line crochet needle or change the bending needle.

7, the chain line guard needle frame is not fixed: adjust the chain line to protect the needle stand position, so that it draws closer to the needle.

Sewing time

1, the pressure line of machine needle line clamp is too loose: tighten the needle thread clamp nut.

2, excessive output of machine needle and thread: adjust needle line.

3. The pressure of the lower bending needle clamping plate is too tight, causing the needle thread to be pulled down: the rotary Panasonic bend needle thread clamp nut or the adjustment.

Take-up rod.

Sewing time is tight.

1. The number of take-up wires on the needle is not enough: remove the thread from the needle bar, so that each needle can send enough line.

2, the pressure line of machine needle line clamp is too tight: loosening machine needle thread clamp wire plate nut.

3. Under the bending needle, too much outlet line or under bending, the pressure of the needle clamp plate is too loose: reduce the outlet quantity of the lower bending needle or tighten the lower bending needle thread clamp nut.

The upper curve is tight or loose.

1. The position of the upper bending needle axis is not adjusted too high or too low: re adjust the axis position of the upper bending needle.

2. The upper bending needle line clamp plate is too tight or loose: unscrewing or tightening the needle thread clamp nut.

Bend or tighten the needles.

1. The position of the lower bending needle pendulum bar is not adjusted too high or too low: the position of the lower bending needle axis is re adjusted.

2. The lower bending needle clamp plate is too tight or too loose: loosening or tightening the clamping plate to achieve micro pressure, and there must be no excessive pressure.

Crease of sewing seam

1. The feed ratio is too small: move the differential hand down until the seam is smooth.

2. Press the foot surface and the feeding tooth plane uneven: adjust according to the technical requirement.

3, control line pressure is too strong: readjust the intensity of control line.

4, the pressure is too strong or too weak: adjust the pressure intensity of the holder.

5, the feeding tooth is too prominent: the correct height of the feeding tooth is adjusted.

6, the knife can not quickly cut 6. sharpening blades or new products, check the upper and lower knives.

7, differential feeding does not match: adjust appropriate differential feeding.

8.

Too thick: choose suitable thread and needle.

9, the width of the edge is narrower than that of the needle tongue: adjusting the width of the edge or changing the tongue.
