5 thread overlock sewing machine, qhov tshwm sim ntawm" koob hla" thiab" xov jamming" ntawm lub tshuab feem ntau ntsib.
Hauv kev lag luam tsoos tsho, dav dav 4 xov tshuab txheej txheem knitted fabrics, thiab cov5 thread overlock sewing machine processes woven fabrics. However, with the development of the times, the technological requirements of garment production have also changed. It is required to process Knitted Fabrics with 5 thread sewing machine, the fabrics are particularly soft. During sewing, the phenomenon of "needle skipping" and "thread jamming" of the machine is often encountered.
Ntsiab lus 1:
Nyob rau hauv ib txwm muaj, qhov kev ncua deb ntawm 5 xov saw stitch dabtsi yog khoov koob thiab lub tshuab koob yog nruab nrab ntawm 1.6 hli thiab 1.8 hli. Txawm li cas los xij, thaum ua cov ntaub knitted, vim tias cov ntaub tshwj xeeb yog mos, cov ntaub yuav nce thiab nqis nrog lub tshuab koob, yog li nws tsis yooj yim los khaws cov xov nplhaib, uas yog tshwj xeeb tshaj yog yooj yim ua rau rab koob hla. Yog li ntawd, thaum peb ua Knitted Fabrics, peb yuav tsum kho qhov kev ncua deb ntawm 5 xov saw stitch dabtsi yog khoov koob ntawm luboverlock tshuab xaws and the machine needle to 2.0mm-2.2mm. If the distance is too large, the empty step on the machine will not form chain lines; If the distance is too small, the needle will jump, so its distance must be adjusted.
Ntsiab lus 2:
Thaum ua knitted fabrics, tus nqi ntawm lub zog ua ntej thiab tom qab khoov koob yog loj heev. Thaum lub tshuab rab koob poob, nws yuav tsis muab tso rau hauv tsib-xov nplhaib, ua rau rab koob hla. Yog li ntawd, peb yuav tsum tau kho lub pem hauv ntej thiab nram qab txoj hauj lwm ntawm cov saw stitch dabtsi yog khoov koob nyob rau hauv qhov chaw, uas yog, qhov sib txawv ntawm lub dabtsi yog khoov koob thiab lub tshuab koob yog 0.01 hli thaum lub koob yog hooked. Tom qab lub tshuab rab koob rov qab, ntxig rau hauv qab ntawm rab koob khoov, thiab qhov sib txawv ntawm lub tshuab koob thiab rab koob khoov yuav tsum me me.
Thaum hloov kho, peb tuaj yeem qhib lub hau ntawm ib sab ntawm lub presser ko taw lifting pas nrig thiab pom tias muaj cov ntsia hlau nyob hauv nruab nrab. Loosen cov ntsia hlau nrog Allen ntswj ntsia hlau thiab txav tus pas txuas txuas kho qhov pem hauv ntej thiab nram qab txav ntawm cov saw stitch dabtsi yog khoov rab koob mus rau hauv qab kom txo qis pem hauv ntej thiab nram qab txav ntawm cov saw stitch dabtsi yog khoov koob, thiab tom qab ntawd ceev cov ntsia hlau.
Key point 3:
Qhov sib txawv ntawm saw stitch dabtsi yog khoov koob thiab tshuab koob
The normal gap between the 5 thread chain stitch bending needle and the machine needle is between 0.05mm-0.1mm, but when making knitted fabrics, the machine needle thread ring is not easy to form, so we need to adjust the plane gap between the chain stitch bending needle and the machine needle to 0. If the clearance is adjusted to 0, it is easy to break the needle when making a thicker joint. At this time, we should adjust the needle guard, that is, turn the chain stitch bending needle tip to the center of the needle so that the plane clearance between it and the needle is 0. At this time, the clearance between the needle guard and the needle tip is also 0.
