What s the matter with the sewing machine needle always breaking, and what is the situation when the

1. Break the needle with thick material.

Study: the needle is too thin or tilted, the thickness of the sewing material is uneven, and the needle bar is too large. Treatment: Change to a new coarse needle, adapt to slow down the sewing speed and assist in feeding by hand, and change to a new needle bar or needle bar sleeve.

2. Short needle length, large needle, long needle distance broken needle.

Study: The action of feeding teeth is lagging behind, the feeding teeth are unqualified, and the needle is broken when it touches the rear end of the feeding teeth. Solution: The positioning of the cloth feeding cam should be changed, and it is necessary to reduce the needle distance or replace the cloth feeding teeth.

3. The needle is broken under the needle plate.

Study: The position of the needle is too high, the needle touches the pendulum shuttle, the shuttle bed is not installed, the tip of the pendulum shuttle touches the needle, the gap between the pendulum shuttle and the needle end is too small or too large, and the pendulum shuttle touches the needle or loses the needle protection effect. Solution:

Change the position of the needle bar or needle, install the new pendulum shuttle, and change the gap between the end face of the pendulum shuttle holder and the needle.

4. The needle is broken on the needle board.

Study: The hand sewing material is too violent, resulting in the tilting of the needle, the loosening of the presser foot screw, causing the presser foot to be skewed and touching the needle, the offset of the cloth feeding cam causes the sewing material to pull off the needle, and there are hard objects in the sewing material to break the needle. Solution:

Strengthen the operation exercise, adjust the presser foot to tighten the screw, and change the position of the cloth feeding cam screw.

There are two situations in which the sewing machine needle is always broken.

The first situation is that the quality of the needle of the sewing machine is not good, resulting in always broken needles.

In the second case, the position of the needle is not properly installed, and it is installed too low.

The sewing machine often breaks the needle, the master teaches you to master these 5 points, and novices can easily troubleshoot.

The yarn curtain is always broken, and other fabrics are constantly needled.

The reasons can be found in the following aspects:

(a).Check whether the quality of the sewing thread is acceptable. Stitches that are moldy, deteriorated, or have nodules are most likely to break.

(b).Check that the sewing thread you have chosen matches the needle. The sewing thread is too detailed and easy to break due to insufficient tenacity; If a thin needle is equipped with a thread that is too thick, the thread will not pass through the pinhole and will be cut.

The use of simple double-thread seam eliminates the trouble of using a special seam machine for more than three threads, which not only reduces the manufacturing cost of the product itself, but also integrates sewing and seaming, which is the unique function of the product.

Features::

1. Straight sewing (double line) - with bottom line design, sewing is firmer.

2. Curve sewing (can be done as a double-thread sewing) - the shape is shown in the figure, and the simple sewing work of the fabric can be easily completed at home, without looking for a tailor shop.

Some buyers have reported that the shape of this seam is different from the seam of ready-to-wear garments on the market, because the seam that is usually seen is machined with a special three-wire or four-wire seam machine, while our products are double-threaded. Although the shape is different, it can also achieve the purpose of locking the edge of the fabric without dispersion.

If the electric sewing machine often breaks the needle, there are several reasons: First, the presser foot fixing screw is not tightened. Exclusion method: Check the position of the presser foot screw and the presser foot, and tighten the screw.

Second: the needle plate is narrow, and the coaxiality error between the pinhole and the needle is too large. Exclusion method, to re-select the needle plate or adjust the needle plate screw, until the needle and needle plate hole coaxiality error within millimeters.

Three: the needle and the cloth feeding tooth are not well matched and not synchronized. Elimination method, adjust the movement of the needle and the feeding tooth.

Fourth: the needle stroke is incorrect, and the movement of other mechanisms is not properly coordinated. Exclusion method: Check whether the needle stroke crank screw is fastened to the groove.

There are many reasons for the broken thread of the electric sewing machine, mainly there are broken bottom lines and top threads, and the common ones are as follows:

1. If the line is not adjusted, it will be disconnected. Solution: A good way to adjust the line is to adjust the bottom line first, and the bottom line should be after the core is placed in the shuttle sleeve, and it is advisable to hold the wire and the shuttle sleeve slowly down in one hand, and then adjust the surface line according to the bottom line.

2. If the presser foot is not adjusted properly, the line will be broken. Solution: There is friction between the side of the presser foot and the needle when adjusting the pressure foot, and the presser foot should be shaken from side to side to see if it will touch the needle.

3. The gap between the shuttle bed and the needle tip is too large and the thread is broken. Solution: The distance between the hook hook and the needle groove should be less than the easy needle breakage when adjusting the shuttle bed.

4. If the fabric is too thick, the thread will break. Solution: Tighten the screws on the top of the presser foot to make it have a certain amount of pressure.

5. If the fabric is too thin, the thread will break. Solution: When sewing, the presser foot goes out of the fabric and breaks the thread.

6. If the needle rod and the shuttle bed are not synchronized, the thread will be broken. Solution: When adjusting the needle rod, use a shuttle sleeve to put it on the needle plate, and the needle bar is just adjusted to the height of a shuttle sleeve, and then adjust the shuttle bed.

7. The bur pinhole is too sharp and will break the thread. Solution: It is recommended to use a round-headed pin, but it is a little more expensive.

There are also some reasons for disconnection due to our operation and improper use. The main ones are as follows:

1. The threading method is incorrect, not according to the correct line, check whether the top line is worn wrong or less than a certain line crossing. The stringing should be done correctly according to the instructions on the manual.

2. The needle is installed incorrectly, such as the needle long groove is reversed or skewed. The correct way to install it is to have the needle groove facing the operator. It is also possible that the needle eye and needle groove are not smooth, and the needle should be replaced with a new needle.

Check that the needle type is suitable, that the height of the needle bar adjustment is accurate, and that the needle is attached to the top of the needle bar. If the needle is too high or too low, it will affect the hook threading.

3. Suture problems, one is that the tension is too large, and the suture tension should be adjusted appropriately; Second, the quality is too poor, so better sutures should be used instead; Third, the suture is thicker than the eye of the needle, and the appropriate suture or needle is used.

4. If there are burrs or scratches on the needle, curved needle, needle board, presser tongue, wire hole and other parts, re-polish it with oil stone or fine sandpaper, if the scratch is serious, it is necessary to replace the parts.

5. There is fiber fluff in the shuttle, and the fluff and the thread are twisted with each other, so that the thread becomes thicker, and the thread will break if it cannot pass through the pinhole. Check whether there is cotton dust and dust accumulated in the cloth feeding teeth and shuttle bed, and pay attention to keeping it clean and clean frequently, so as not to affect the formation of the line step.

What is the problem with the broken needle of the sewing machine: the sewing machine jumper generally has the following possibilities: 1. The failure caused by the needle bend or needle installation can be replaced with a new needle or the needle can be installed correctly, 2. The tension of the wire pick spring is too large or there is no fault caused by the wire pickup spring, the wire pick spring can be relaxed and the wire pick spring can be solved, 3. The fault caused by the burr at the tip of the hook can be gently ground off with fine sandpaper, 4. The fault caused by the position error between the hook and the needle is too large, and the position of the hook and the needle can be solved by adjusting the position of the hook and the needle.

The specific operation is as follows: a) Adjust the up and down position of the needle and the hook First, the needle is rotated to the bottom, and then slowly continue to rotate when the needle slowly moves upward, the tip of the hook should be moved to the middle of the needle plane, if it is not adjusted. b) After completing the adjustment of a, you can adjust the position between the needle and the hook tip, and the operation is as follows:

Adjust the distance between the hook tip and the needle to 0, and then tighten the fixing bolt of the hook.

There are many reasons for the thread breakage of the sewing machine, there are broken bottom lines and top threads, the most common are the following: 1. The line will be broken if it is not adjusted well (the best way to adjust the line is to adjust the bottom line first, and the bottom line should be after the core is placed in the shuttle sleeve, hold the thread in one hand, and the shuttle sleeve should fall down slowly, and then adjust the surface line according to the bottom line) 2. The presser foot will break the thread if it is not adjusted well (there is friction between the presser foot and the needle when adjusting the pressure foot, and the presser foot should be shaken left and right to see if it will touch the needle when adjusting the pressure foot) 3. The gap between the shuttle bed and the needle tip is too large and the thread is broken (the distance between the hook hook and the needle groove should be less than the easy needle breakage when adjusting the shuttle bed.) 4. If the cloth is too thick, the thread will break (tighten the screw on the top of the presser foot to make it have a certain pressure) 5. The fabric is too thin and the thread will break.

When sewing, the presser foot goes out of the cloth and breaks the thread) 6. The needle bar and the shuttle bed will break the thread if they are not synchronized (when adjusting the needle rod, use the shuttle sleeve to put it on the needle board, and the needle bar is just adjusted to the height of a shuttle sleeve, and then adjust the shuttle bed) 7. The needle hole of the bur is too sharp and the thread will break.

If you still have time, please give me a thumbs up! Thank you! Good luck with your studies! Good luck!

What should I do if the sewing machine breaks the thread? There are two steps: look at the needleboard, and one more step is very important, simple and practical!

Summary. Hello dear <>, 1The upper line is too loose, and the lower line is tight. Adjust the clamping wheel so that it clamps the upper line. If the bottom thread is still tight, remove the small wire wheel under the bottom and loosen the small screw of the clamp wire a little. Maybe it's going to take a few trials and turns to get it right.

2.Look at the manual, the crimping board can also be adjusted, it may be too tight, just adjust it loosely. Generally, it is directly above the needle, and there is a screw on the top of the machine head that can be screwed by hand.

The lower feeding teeth can also be adjusted, and there will be a big button on the fuselage, and there is a scale (or a fine scale of the pins) to adjust it in the direction of the stitches. Your machine may be caused by over-pins.
