The computer sewing machine crashes after returning the needle, and how to adjust the total broken t

Hello, I am glad to answer for you: the total thread disconnection method of the computerized sewing machine is as follows; 1.The two threads in the sewing machine may be too tight, and the Qingjing imitation adjustment screws in front of the machine head can be adjusted and adjusted to the appropriate tightness.

2.The needle is thin and thick, so that the wire can not enter the wire slot, resulting in the wire breakage, and the appropriate needle and thread can be used to accompany the draft. 3.

The shuttle inside the sewing machine has fiber fluff inside, and the fluff and thread are twisted with each other to make the thread thicker, and it can be cleaned properly. 4.There may be dirt inside the shuttle inside the sewing machine, clean it manually, and add an appropriate amount of sewing machine oil.

Summary. Hello, dear, I am happy to answer for you: what is going on with the needle drop of the computer sewing machine If the sewing machine is often broken, there are the following problems:

1. There is a problem with the needle, and the needle is rough and bent. The hole is not smooth, try to change the needle. 2. The needle is thin and the wire is thick, and the wire cannot enter the wire duct and is easy to break.

3. The upper line is too tight, and the adjusting screws in front of the machine head can be adjusted. 4. Check whether the distance between the needle and the suspension cable is too close when it falls to the bottom, and then adjust. 5. Whether the cleaning is not very good, whether the lubrication has kept up, 6. Whether the quality of the second line is not good.

7. The needle is too thin and the fabric is too hard. The details are as follows: (1) Check whether the noodle thread is worn incorrectly or missing a certain thread crossing.

2) Check whether the needle is installed correctly, such as the needle long groove is reversed or skewed. Slightly curved needles are difficult to identify directly with the naked eye, but can be identified by placing the needle on a platform and turning it.

Just cleaned up and changed the oil.

The problem of the hook is generally that the hook is hurt when the needle is broken, so that the place where the hook crosses the line is not smooth, and it is good to grind it smooth with fine sandpaper.
