A thick thread zigzag sewing machine is a special sewing machine, also known as a meaisín fuála zigzag. Úsáidtear meaisíní dhá phointe agus meaisíní trí phointe go coitianta, rud a chuireann go mór le ráta gníomhaíochta an trealaimh. tá an meaisín fuála comhdhéanta de cheann meaisín, bonn, tarchur, agus gabhálais. Is é an ceann an phríomhchuid den mheaisín zigzag. Tá an tsamhail áirgiúlachta comhdhéanta de cheithre mheicníocht piocadh, crúca snáithe, tógáil snáithe-suas, agus beathú, chomh maith le meicníochtaí cúnta amhail foirceannadh sreinge, brú ábhair, agus titim fiacail. Tá gluaiseacht gach meicníochta comhordaithe go réasúnta agus oibríonn sé go ciorclach chun an t-ábhar fuála a shéaladh.
Tá anmeaisín fuála zigzag will produce mechanical fatigue after long-term use. The coordination of various parts is not as good as before, and some small faults will occur. If the sewing material is wrinkled, it is due to the broken tip of the needle, the excessive tension of the bottom thread, and the improper adjustment of the differential mechanism. At this time, we should replace the needle, loosen the shuttle spring screw and readjust the differential mechanism. The reason why the lower part of the sewing material is "gnawed" to form grid tooth marks is that the tip of the cloth feeding tooth is too sharp and the pressure of the presser foot is too high. We can use an oilstone to polish the tip of the feeding teeth and loosen the pressure regulating screw of the presser foot. There is wired wool under the sewing material. There is a sound of breaking the fiber during sewing, which is due to the broken tip or too blunt of the machine needle. Resolutely replace the new needle. It is estimated that the stagnation of sewing material is due to too low feeding teeth and too high presser foot pressure. At this time, raise the cloth feeding teeth and tighten the pressure regulating screws.
Bogann an t-ábhar fuála siar agus amach freisin toisc go bhfuil na fiacla beathaithe ró-ard agus is gá iad a choigeartú. Is é an fáth nach féidir an réad fuála a bheith fuaite siar ná nach mór an t-athrú cam beatha agus suíomh an cham beatha a choigeartú freisin. Tá skew neamhrialta an ábhair fuála freisin mar gheall ar shuiteáil cam na fiacla beathú éadach nó scriúnna scaoilte an mhadra beathaithe éadach. Díreach na fiacla beatha a cheartú agus na scriúnna fiacla beatha níos doichte.
De ghnáth, is féidir leat níos mó a bhreathnú agus a achoimriú i do chuid oibre, agus is féidir leat lochtanna beaga anmeaisín fuála zigzagleat féin gan iarraidh ar aon duine eile.
