Broken thread of electric sewing machine


It is very common for electric sewing machines to have cross-hatching problems during the working process. When encountering such problems, we must first check the following problems:

1. Upper thread: Check whether the upper thread is installed correctly, check whether there is any error in threading, and see if the pressure of the upper thread is too high, and if it is too large, loosen the pressure.

2. Needle: Then check whether the installation of the needle is in place. The needle must be installed to the top to ensure that the needle is installed correctly and that the needle is not damaged or broken.

3. Bobbin: Next, we need to check whether there is any problem with the bobbin. First, check whether the bobbin is damaged, or something is stuck, and then look at the winding of the bobbin. Too full, too loose, and too messy will cause the bottom thread to be poorly threaded during the sewing process, which will also cause thread breakage.

4. Sound: The problem of the machine can also be judged by the sound of the machine when it is running. If the sound is too loud when the machine is running, and it is different from the usual, it means that there may be a problem with the machine. At this time, it is necessary to check it comprehensively to prevent the machine from forcibly operating and be damaged.

When there is a problem with the machine, we must first find out the cause of the problem. If it is a problem that can be solved by ourselves, we can solve it by ourselves. If it cannot be solved by ourselves, we need to ask a professional to solve it.
