Round Head Lock Machine Maintenance Tips

< p > round nose keyhole machine is a special sewing machine which is relatively complex in manufacturing technology and requires precise and detailed process requirements.

The machine is mainly used for keyhole sewing operations of all kinds of middle and high grade garments, so it is also called Feng Yan keyhole machine.

< p > the main products of the round head keyhole machines in the domestic market are: Germany's 557\558 mechanical round eye keyhole machine, 579\580 computer round head keyhole machine, the United States is the 101\100\104 mechanical round eye keyhole machine, the Japanese heavy machine 3200 computer round head keyhole machine, the Japanese brother 9800 computer round eye keyhole machine and other foreign brand products, and the domestic Guangzhou Southern China brand, Shanghai Kai Gu 1-1 mechanical round eye keyhole machine, Zhejiang gem card 299U-566 mechanical round eye keyhole machine, 299U-1350A electronic round head keyhole machine and so on.

Next, I will talk about my experience and opinions on the common a href= "http://cailiao.sjfzxm.com/Matertial/show/machine_index.aspx" > fault > /a > for the round head keyhole machine such as jumping needle, broken wire and broken needle.

< p > 1.. Check whether the needle is bent.

If the surface clearance is too large, the needle can not be stitching up, and then we need to change the needle. Then we need to replace the machine needle. 2. check whether there is a barbed wire, and the resulting needle jumping, disconnection, floating line and so on. If this happens, it is recommended to use the steel file to grind and polish with the polishing machine. 3. check whether the wire bending needle is a cable slot, such as the cable slot or the bending needle has been seriously worn out in the long time use, and it appears to be shorter or bent. So it is recommended to replace the hook wire bending needle; 4. rotating drive hand wheel to check whether the concave clearance between the needle tip and the machine needle is too large, the clearance is too large, which may cause the needle to not jump to the needle line. If the machine needle is bent, it will easily lead to the hook and needle.

As long as we rotate the needle to the lowest position, check the distance between the needle and the guard plate. If the distance is too far, we can not rely on the guard plate. Then adjust the match between the guard plate and the needle. (Note: the close proximity of the needle should not be the location of the top needle), the gap between the needle tip and the needle should be adjusted to 0.1mm; 5. in the whole rotation process of the crochet seat, the clearance between the crochet needle and the needle should be kept at the same position. When the needle is picked up, the needle should start at the 2mm position above the pinhole.

After adjusting the position of the crochet and the needle, we must tighten the fastening screws of the hook wire in time, and then check the matching of the fork and the needle.

The line between the fork pin and the bending needle can not be tightly attached. The right fork is as close as possible to the top of the right hook needle, but it can not touch the back of the right curved needle, and must be in the middle of the back of the bending needle.

The left branch fork is as close as possible to the top of the left hook bending pin, and the fork must be aligned to the corresponding line hole on the left bending needle.

< p > in addition, according to the thickness of the suture, we can properly adjust the gap between the split fork and the bending needle.

The branch fork is blocked by the block under the pressure of the spring, and tighten the retaining screw. If the left fork is too short or the wear is large, then the left branch fork must be replaced.

< /p >

< p > at the same time check the position of the fork and the toggle plate.

Turn the pmission handwheel, pfer the needle bar to the lowest position in the "dead center" position. When the needle is punctured, the clearance between the dividing bar and the fork arm must be exactly the same as the gap between the dividing plate and the fork arm. If during the long time of use, the grooves can be grooves, then the distributor must be replaced, and the position is adjusted again.

< p > < strong > broken pin fault < < /strong > < /p >

< p > during the sewing process, a broken eyelet failure occurs frequently.

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.

< /p >

< p > secondly, because of the hardness and thickness of the fabric made by sewing, the needle is easily broken.

In view of fabric hardness, uneven thickness and special parts sewing, we should change the needle into the corresponding model or better quality machine needles.

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.

< /p >

< p > finally, check whether the bending needle and the needle are too close or touch the needle, check whether the fork is touching the needle or the top needle in the process of dividing, because of the above two reasons, we only need to adjust the gap between the left and right bending needle and the machine needle, and adjust the split fork to the middle position of the bending needle.

< p > < strong > broken line fault < < /strong > < /p >

The broken short line fault of < p > round a href= "http://cailiao.sjfzxm.com/Matertial/show/machine_index.aspx" > keyhole machine < /a > 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.

< /p >

< p > secondly, check whether the 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.

< /p >

< p > 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.

< /p >

< p > 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, there will be skipping and disconnection. We can adjust the gap between the left and right needle tip and the concave surface of the needle, turn the machine with the handwheel, and when the needle goes to the lowest point and then rise to 2.7mm, it should start at the 2mm position above the pinhole. The line loop is the largest and easiest to hook up, and it is not easy to produce the phenomenon of "a href=" http://cailiao.sjfzxm.com/Matertial/show/Garment_Accessories.aspx > /a "/a".
