Common faults of sewing machines
The presser foot can’t move: The feeding of the sewing machine mainly depends on the presser foot and the cloth feed dog to move the material, so when there is a problem with the feeding, we can check these two points first. If the pressure of the presser foot is too small, the fabric will not be pressed tightly, and irregular movement will occur when the material is fed, or it will not be able to move. The pressure adjustment nut can adjust the pressure of the presser foot, and it is enough to adjust the pressure to an appropriate range. Because the thickness of different materials is different, the height of the presser foot also changes accordingly.
The thread trimmer has a short bobbin thread; check the tightness of the fork, it is most suitable for the bobbin thread to be able to be pulled by hand after the fork is fastened. Check whether the bobbin case is deformed, the deformation of the bobbin case will affect the tension of the bobbin thread. Check the combined knife depth, the shallower the combined knife depth, the shorter the bottom line.
Cutting the continuous line: This also needs to check whether there is any problem with the joint knife. If the joint knife is too shallow, there is no way to cut the line; another possibility is that the line separation angle is too large or too small. At this time, it is necessary to check whether the line separation angle is at 310°~315°between.
