What is the reason for the abnormal color change of the thick material outside machine
When sewing with a thick outer thread machine, abnormal color changes may occur, the color change is not in place, and the color remains unchanged. These problems will directly affect the sewing efficiency of the thick outer thread machine. What is the cause of this problem?
The abnormal color change of the thick external thread machine may be caused by the abnormal needle position, which requires us to use a wrench to pull the color change cam of the color change box to detect. If the needle bar on the head does not move up or the thread take-off lever falls off, the color is changed The cam will usually get stuck. If the trigger is easily pulled up and the device can be activated after the needle is positioned, the color-changing power supply board is faulty.
If the color of the thick sewing machine changes abnormally, it can also change clockwise and counterclockwise. So we need to check whether each connection device on the power board is firm. If it is damaged, it needs to be replaced in time. Secondly, check whether the fuse of the power board of the thick material external line machine is a fuse. If necessary, replace the fuse in time.
How to solve the threading problem of the thick material double needle outer thread machine
The thick double-needle outer thread machine is the best in the industrial outer thread machine. It has many advantages in sewing thick materials, so many industries will use it to complete the sewing of thick materials, but in the sewing process, there will be more or more There are few problems, so today we will solve the thread problem of the thick material double needle outer thread machine.
When using a thick two-needle outer thread machine, it may happen because the sewing worker does not pay attention to the bottom thread or the bottom thread is too long, but the place where this happens is not fixed.
In view of this situation, it is recommended to choose a special bobbin case with anti-idling reeds. When using an extra-thick outer thread machine, the sewing speed can be reduced, especially when the thread is cut, the cutting time will also slow down; pay attention to the winding of the bobbin The amount should not exceed 85% of the bobbin; the reverse installation of the bobbin makes the direction of rotation of the bobbin opposite to the direction of inertia of the bobbin; ensure that the gap between the bobbin and the bobbin case is as small as possible.
