How To Solve The Problem When The Stitching Machine Is Not Stitched On The Long Seam?

When the equipment starts to start the needle, the needle thread is on-line at the same time, but sometimes it appears that the long needle is not on-line when it starts, sometimes it can not be on-line for several centimeters.

When the needle is intact and the machine position is accurate, the needle must be considered when the needle is not on the line. Sometimes the line is unstable because of the large twist of the line produced by the manufacturer, because the long needle is the farthest needle of the crooked needle hook, so the coil formed is the biggest one.

When the quality of the wire is not good, the coil will distort and distort when the coil is in the process of forming, so that the needle is not easy to hook into the long needle coil.

First, remove the long needle thread from the small clamping plate of the needle bar, so that the coil formed can be reduced, and the coil will not be twisted easily.

Two. Put one piece under the needle, open the movable side cover and the movable draw plate on the table, turn the wheel on the machine with your hands, and then look at the needle and the needle from the survey.

It will be found that when the bending needle begins to enter the long needle ring, the wire loop is distorted, and the crooked needle hook is not on the line.

The machine needle can be tilted to a certain degree according to the distortion of the needle and thread. The machine needle coil can cater for the bending needle to enter the line loop (the needle can only change direction slightly, if too many will cause a jump needle).

Three, if the above method can not solve the problem, the needle bar can rise about 0.5mm, so that the wire loop of the needle is smaller.

In addition, bend the needle hook time a bit earlier, because when the bending needle enters the long circle, the bending needle is just in contact with the needle hole line, the bending needle moves to the left, and the contact between the bending needle and the machine needle line, the two are mutually rubbing, driving the coil to the left deformation, causing the coil distortion to change more quickly.

If the bending needle is advanced a bit, the bending needle enters the coil, and then the friction occurs on the line below the bending needle, causing the coil to deform. When the bent pin enters the coil completely, the coil can not slide out of the curved needle tip.
