Common usage problem-solving methods

Question 1: The needle is missing. There's nothing on the back. The needle is inserted empty. On the front, it's a straight line. Pull it off!

Solution: The needle has skipped. Once pulled off, it will definitely come off because the thread on the reverse side is not interlocked one by one. Under normal circumstances, it should be fastened properly. The problem causing the needle to skip is that the fabric feeding speed is too fast, and the machine doesn't have time to fasten the loop on the back. Don't move your hand holding the machine. Let the machine feed the fabric by itself. If it still remains in a straight line, you need to adjust the machine! If you don't know, please ask the customer service. We will teach you!

Question 2: There's a bunch of wires on the back. It's stuck!

Solution: There are always a bunch of wires on the back of the machine, which keeps getting stuck and unable to move. The reason is that the fabric feeds in too slowly. Don't move your hand holding the machine. Pull the fabric on the left side of the machine to make it feed in faster. That's it.

Question 3: My stitches keep breaking or coming out so loose!

Solution: The wires keep breaking. When threading the diagram, only thread 1-3-4. Do not place the wires at 2 and hold them. Holding them will definitely break

. Frequently asked questions for use

I. How to repair sewing machine skipped stitches or broken threads
You must have tied up thick insoles. It's very likely that the fabric delivery time was wrong. Besides Check if the needle is crooked. This can also happen if the needle is crooked.

Second, why can't my mechanical sewing machine attach to the bottom line? Check if the needle is bent.
It is usually the case that the tip of the rotary shuttle and the machine needle are not placed externally. The gap between the spindle tip and the machine needle is 0.5mm. The time between the spindle tip and the machine needle is 1.5mm(which is 1.5mm above the needle hole).

Iii. Jumpers
1. The threading method is incorrect. Re-thread according to the "threading diagram"

2. The installation of the straight machine needle is incorrect. Check the height and orientation of the machine needle so that when it moves downward, it is slightly in front of the hole on the needle plate

3. If the tip of a straight machine needle breaks or bends, replace it with a new one

4. If the tip of a curved needle becomes dull, it can be polished with an oilstone or fine sandpaper, or a new curved needle can be replaced

5. If the tension of the suture is too high or too low, adjust it appropriately

6. The curved needle cannot fit the loop of the straight machine needle on the right. The loop of the straight machine needle on the right side of the lower decorative thread is too small. Increase the amount of the loop appropriately

7. The curved needle must not fit around the loop of the left straight machine needle. If the left trace of the lower decorative thread jumps and the loop of the straight machine needle is too large, the amount of jumps should be appropriately reduced

8. If the curved needle cannot hook the middle and left straight machine needle loops at the same time, and both the middle line and the left trace of the lower decorative line skip stitches, the amount of skipped stitches should be appropriately reduced

9. The middle and left side of the back of the curved needle must not pass through the knitting needle and the triangle of the curved needle. Check whether the middle of the back of the left stitch passes through the thread clamp and the synchronous operation of the bottom line CAM. If there is a problem, adjust it according to the standard

10. Improper fit between the machine needle and the curved needle: Check the height of the needle rod and the synchronization between the machine needle and the curved needle. If there are any issues, adjust them according to the standards

11. Improper fit between the machine needle and the needle guard rod: Check the positions of the machine needle and the needle guard rod

12. Improper fit between the machine needle and the tensioning needle or incorrect position of the tensioning needle can cause the decorative thread to skip stitches. Check the fit dimensions of the machine needle and the tensioning needle, and inspect the thread output of the tensioning needle

Four. Disconnection

1. The threading method is incorrect. Re-thread according to the "threading diagram"

2. The machine needle is not installed correctly. Reinstall the machine needle to ensure that the needle slot is directly aligned with the operator

3. If the needle holes and needle slots of the machine needle are not smooth, replace it with a new one

4. The tension of the stitches is too high. Adjust the tension of the stitches appropriately

5. If the quality of the stitching is too poor, switch to better stitching

6. If the thread is thicker than the needle hole, switch to a moderate thread or a machine needle

7. If there are burrs or scratches on the machine needle, curved needle, needle plate, presser tongue, wire passing hole and other wire passing holes, they should be re-ground with an oilstone or fine sandpaper, or the scratched parts can be replaced

8. If the machine needle does not fit properly with the curved needle or the taut needle, readjust it according to the fit standards for the machine needle, the curved needle or the taut needle

V. Broken needle

1. The pressure of the presser foot is too small, resulting in poor fabric feeding and broken needles. Appropriately increase the pressure of the presser foot to ensure normal fabric feeding

2. If the curved needle collides with the straight machine needle, adjust the fit position of the curved needle and the straight machine needle according to the standard

3. If the taut needle collides with the straight machine needle, adjust the fit position of the taut needle and the straight machine needle according to the standard

4. Improper fit between the straight machine needle and the needle guard rod. Adjust the fit between the machine needle and the needle guard rod according to the standard

5. If the tip of the curved needle is bald, replace it with a new one

6. The needle rod and the needle rod sleeve are worn too much, causing the fit between the needle rod and the needle rod sleeve to loosen. Replace the needle rod and the needle rod sleeve

7. If the needle holes on the needle board are too small, replace it with a needle board with larger needle holes or switch to a smaller machine needle

8. If the machine parts are loose significantly, check the fit and wear between each part of the hook and line mechanism. Adjust the matching dimensions according to the standard. Replace the severely worn parts

Six. Flower needle

The straight machine needle is too low, causing the straight machine needle coil to form too large and interweave with each other. Reposition according to the height positioning standard of the straight machine needle

2. The tongue of the needle board is too narrow, causing the straight needle loops to easily come together. Replace it with a new needle board

3. If the bottom of the curved needle is too narrow and circular, it is also easy for the straight needle loops to not separate from each other on the curved needle, causing the loops to interweave with each other and resulting in a flowered needle. Replace it with a new curved needle

4. Adjust the fit position of the straight needle and the curved needle according to the standard

Seven. Wrinkling of the sewing material

1. The differential feeding ratio is inappropriate. Adjust the differential feeding ratio appropriately

2. If the height and front-back position of the feeding teeth are inappropriate, adjust the height and front-back position of the feeding teeth according to the standard

3. If the tension of the suture is too high, adjust the tension of the suture appropriately

4. If the pressure of the presser foot is too high or too low, adjust it appropriately

5. The small presser foot loses its flexible up and down movement. There are seams embedded between the large and small presser feet or rust. Remove foreign objects between the large and small presser feet. For rust, remove the rust or replace the rusty presser foot

Viii. Poor trace quality

1. If the thickness of the thread varies, use better sewing thread instead

2. If the wire clamp is not working properly, remove the dust inside the wire clamp to ensure smooth wire passing

3. The wire feeder is not positioned correctly. Adjust the tension of the needle and thread, bent needle and thread, and stretched needle and thread

4. The wire passing holes are not smooth. Grind or polish the wire passing holes

Ix. Needle Holes

1. Replace the straight machine needle if its tip is blunt or hairy

2. Compared with the sewing material, if the machine needle is too thick, switch to a thicker machine needle

3. If the needle plate holes are too small or have sharp corners, round the needle plate holes

Generally speaking, there are several aspects of needle skipping in a sewing machine:
A: The height of the feeding teeth is incorrect
B: The height of the needle rod is not in place
C: The downward curve needle stroke is incorrect
D: The needle protection time and intervals are incorrect
E: The timing of the lower bending needle loose thread CAM is incorrect
