Repair Of Faults Such As Thread Rolling Of Double Needle Zigzag Sewing Machine
As a relatively simple decor model, Double needle zigzag sewing machine It is widely used for decorative sewing operations in clothing, shoes and hats, underwear, gloves, leather, bags and other industries. This machine is used for double needle swing sewing, and the formation of single rotary hook and thread loop is poor, which brings great challenges to maintenance and debugging. At present, the most common faults of most double needle zigzag sewing machines on the market - thread rolling, needle tip hair, etc.
Next, taking the Zoje 457d double needle zigzag sewing machine as an example, combined with my years of practical experience, I will briefly introduce some maintenance experience of the double needle zigzag sewing machine for thread rolling, needle tip hair and other failures.
Rolling line fault
When the new equipment is just used, It can be said that the phenomenon of "thread rolling" is very common. Because the user usually sews with a slightly thicker silk light than the ordinary sewing thread when using the equipment to enhance the decorative effect, in addition, the equipment operates with two needles at the same time (that is, two silk lights must pass through the rotary hook at the same time) In general, the fit clearance of new rotary hook is very tight, so rolling line faults often occur.
In this regard, I suggest that the maintenance workers or operators use abrasive sand for grinding treatment. It is not easy to appear if the clearance of the rotary hook is slightly larger“ Rolling line ”Has; Or we can replace the old and new shuttle frames, and the effect is also good.
Hairling fault of needle tip
As for the fault of "hair on the needle tip", the author believes that this fault is mainly caused by the shuttle used randomly. It is suggested that clothing enterprises should use the shuttle on ordinary embroidery machines. Because the outer circle edge of the shuttle center is not easy to touch the needle tip, the use effect is good.
In addition, if the threading wire on the bobbin sleeve is deformed and bent inward, it is also easy to touch the needle tip, which will lead to needle breakage in serious cases, so we must pay attention.
It is worth noting that any equipment can meet the needs of different users as long as it is flexibly debugged on the premise of mastering the principle, and the double needle zigzag sewing machine is no exception.
As long as we flexibly adjust the feeding time and the needle swing time, we can adjust the triangular needle with completely different shapes. For example, adjust the needle swing time to Needle tip hair When the fault is about to leave the sewing material but has not completely left, the needle starts to swing, so the triangle needle shape is different from that of the standard swing needle.
