Shirt placket lockstitch machine abnormal processing method

Shirt placket lockstitch machine in the use of the process may encounter a variety of abnormalities, for these abnormalities, the following are some common treatment methods:

First, the broken line processing
Re-threading: When the machine displays “broken line fault” alarm, first check and re-threading to ensure that the line is smooth and unobstructed.

Check the display: Operate the LBH1790A display and follow the steps in the manual for troubleshooting and processing.

Reset and continue sewing: If you decide to scrap the broken placket, click on the large “Reset” icon to make a new placket; if you decide to continue sewing on the original placket, click on the knee switch to continue sewing.

Second, jumping needle troubleshooting
Check the needle and thread: Make sure the needle and thread are correctly selected, the needle is correctly installed, and the threading method and thread tension are appropriate. Check whether the needle and bending needle are damaged, if so, replace them in time.

Adjust the sewing speed: For thin materials, reduce the machine speed appropriately to avoid skipped stitches caused by poor thread loops.

Adjust the thread guide: If the problem persists after lowering the speed, try to adjust the mounting position of the thread guide to improve thread loop formation.

Check the needle and the bending needle with: ensure that the needle and the bending needle with the correct gap and synchronization adjustment, the general gap of 0.05 ~ 0.1mm.

Third, the card needle problem processing
Cleanup and maintenance: clean up the moving parts of the machine before work to ensure that no foreign objects affect the normal operation of the machine. Regularly check and clean the shuttle bed, feed cloth teeth and other parts, to avoid the accumulation of debris such as cloth chips lead to card needle.

Choose the right needle type: choose the right needle according to the type of fabric, to avoid mismatch between the needle and the fabric, resulting in needle jamming or needle breakage.

hread knotting problems
Adjust the bobbin tension: to avoid excessive bobbin tension leading to knotted threads.

Threading correctly: Make sure the threads go through the threading holes correctly and tighten the constant tension devices.

Check the thread cluster cut: make sure the thread cluster cut is flat to reduce the imbalance of the thread in the running process.

V. Threading Difficulties
Choose the right fabric and wire: Make sure the fabric and wire match, avoid the fabric is too thick or the wire is too thick to cause threading difficulties.

Adjust the needle pressure: properly lift the needle pressure to ensure that the needle can pass through the needle hole smoothly.

Sixth, other abnormal treatment
Check the air pressure and power supply: Make sure the air pressure and power supply of the equipment are stable to avoid abnormalities caused by insufficient air pressure or power fluctuations.

Regular maintenance and repair: clean, lubricate and inspect the equipment regularly, replace the parts with serious wear and tear in time to ensure that the equipment is in good condition.

To summarize, when dealing with the abnormal problems of shirt placket lockstitch machine, it is necessary to carefully observe and check all parts of the equipment and take corresponding measures according to the specific situation. At the same time, regular maintenance and repair is also an important means of preventing equipment abnormalities.
