General Lockstitch Tshuab xaws
General lockstitch tshuab xaws yog qhov tseem ceeb hauv kev lag luam xaws, tsim ib qho yooj yim lockstitch (stitch type 301) los ntawm interlocking koob thiab bobbin threads. Lawv muaj nuj nqis rau stitching ruaj khov, kev ua haujlwm siab, thiab cov khoom siv dav dav.
1. Stitch Formation Txoj Cai
Lub tshuab tsim stitches los ntawm synchronized cov kauj ruam: koob nkag mus, xov lub voj ntes los ntawm kev sib txuas sib txuas, sib cuam tshuam nrog bobbin xov, thiab stitch tightening los ntawm xov coj- nce qib, kom zoo huv si, muaj zog, thiab unravel{1}}cov seams tiv taus.
2. Core Parameters & Structure
Hom txaj: Standard ca - txaj nrog 250-305mm caj pas qhov chaw; ntev - caj npab versions rau cov khoom loj.
Kev ua tau zooMax ceev 4,000–5,000 stti / min; adjustable plooj ntev (0.1-5mm); presser ko taw nqa 5-13mm (txog 30mm rau hnyav- qauv qauv).
Pub System: Hauv qab pub (tus qauv), koob pub (tiv thaiv- plam), thiab cov khoom sib xyaw (rau cov khoom sib tw).
Hook & Bobbin: Vertical-axis loj rotary nuv nrog loj bobbin peev rau tsawg downtime.
3. Cov haujlwm tseem ceeb
Adjustable xov nro (balanced stitches); rov qab stitching (seam reinforcement); tag nrho kaw tsis siv neeg lubrication (hnav yuav txo tau, huv si xaws); computerized qauv muab tsis siv neeg xov trimming, presser ko taw lifting, thiab programmable stitches.
4. Classification & Application
Muab faib los ntawm kev ceev (qis / nruab nrab / siab), koob (ib zaug / ob npaug), thiab lub luag haujlwm (lub teeb- nruab nrab / nruab nrab- hnyav / hnyav- lub luag haujlwm), haum rau khaub ncaws, tsev textiles, khoom tawv, thiab lwm yam.
Xaus
Nrog paub tab, txhim khu kev qha technology thiab versatility, lockstitch machines (mechanical los yog computerized) nyob twj ywm indispensable nyob rau hauv xaws thiab khaub ncaws manufacturing.
