How To Deal With The Broken Needle Fault Of Round Head Keyhole Machine

The broken pin fault is caused by many reasons.

First of all, we can check whether there is a wrong line on each track, and whether the clamp wire is too tight, and adjust the tension of the wire clamp until it is suitable.

If the tension of the clamp is too loose, the reverse line will form the floating line and the throwing line.

Secondly, check whether the machine needle is reversed or bent, or the type of the needle is wrong.

We need to reinstall the needle or replace the needle of the corresponding type.

Again, check whether the small needle plate has burrs or the scar left after the broken needle. If there is, use the diamond file to grind the burrs, then polish the grinding surface with the polishing machine.

We also need to check the left and right bending needles with barbs.

The left bending needle is a needle with a bottom line. We can check whether the wire path is a cable slot. After starting the groove, it is easy to cause the bottom line fault to be broken. As long as grinding or replacing the bending needle, it can be solved.

At the same time, check whether there are burrs and broken pins in the fork, and whether there is barbed or quick opening in the fork of the branch line. If these conditions are found, grinding or polishing or replacing the new left and right fork will be necessary.

Finally, we need to check whether the gap between the bending needle and the needle concave is too large.

If the gap is too large, it will cause skipping and disconnection. We can adjust the clearance between the left and right needle tip and the concave surface of the machine needle, turn the machine with the handwheel, when the needle goes to the lowest point and then rise to 2.7mm, it should begin to hook at the 2mm position above the pinhole. This time line loop is the biggest and easiest to hook, and it is not easy to break the thread.

Broken pin fault

In the sewing process, round nose keyhole machine will appear from time to time.

。

When the equipment breaks the needle fault, we first need to check whether the needle is deformed, because in the long time sewing work, the needle is easily heated and deformed, and it will break the needle.

If the needle is thick, the needle will be bent and broken in sewing.

Secondly, due to the hardness and thickness of the fabric made by sewing, the needle is easily broken.

In view of the hardness and quality of cotton fabric, cotton and cotton fabrics with high quality are smooth, smooth and without yarn.

If the cotton cloth is poor, the clothes will have a lot of knots.

We should replace machine needles with corresponding models or better quality sewing machines.

At the same time, check whether the small needle plate is biased, or too close to the front, too close to the back of the needle to break the needle, and then adjust the small needle plate to the correct position.

Finally, check the curved needle.

Whether or not to get too close or touch the needle, check whether the fork should touch the needle or the top needle in the process of dividing, not only the cost of the inspection of clothing is greatly increased, but also the suppliers and cooperative factories of the green box children's clothing are all up.

Although your electric control part is running well, your frame hardware can not keep up with it, and you can not get good embroidery effect.

Because of the above two reasons, we only need to adjust the gap between the left and right bending needles and the machine needle, and adjust the split fork to the middle position of the bending needle.
