Kev faib cov tshuab xaws los ntawm Hook thiab Xov Mechanism

Cov tshuab xaws tuaj yeem muab faib ua tsib pawg raws li lawv txoj kev sib txuas thiab xov xov:

Feem ntau cov tshuab xaws hauv tsev siv hom kev sib txuas thiab xov tshuab, thiab nws kuj tau ua haujlwm hauv qee qhov kev lag luam thiab kev pabcuam kev lag luam tshuab xaws. Oscillating nuv tshuab xaws tau ntxiv tau muab faib ua pem hauv ntej-qhib thiab rear-qhib hom. Nrog rau yav dhau los, lub bobbin tuaj yeem raug tshem tawm yam tsis muaj kev sib cais ntawm bobbin rooj plaub; koj tsuas yog yuav tsum tig lub bobbin case latch blocks sab nraud. Nyob rau hauv rooj plaub tom kawg, tshem tawm cov bobbin yuav tsum tau tshem tawm cov ntaub ntawv bobbin, ua rau nws yooj yim dua piv rau hom qhib pem hauv ntej. Vim lub oscillating tsab ntawv tsa suab ntawm tus nuv nyob rau hauv no hom ntawm lub tshuab xaws, ua tiav los ntawm lub reciprocating txav ntawm tus neeg tsav tsheb shuttle, muaj ib tug ntau inertial nyhuv. Yog li ntawd, cov tshuab no tsis haum rau kev kub ceev. Qee qhov kev lag luam oscillating nuv tshuab xaws qhia qhov siab tshaj plaws ceev txwv ntawm 2500 revolutions ib feeb (r / min). Tshaj qhov kev txwv no ua rau lub tshuab hnav thiab ua rau lub tshuab lub neej luv.

Feem ntau cov tshuab xaws tshuab txais yuav hom tshuab no vim tias lub tshuab xa hluav taws xob tig thaum tsim cov stitches, cia lub tshuab ua haujlwm ntawm kev kub ceev. Qhov tseeb, rau txhua txoj hlua, lub tshuab xa hluav taws xob tig ob zaug. Yog li, ntawm lub tshuab xaws nrog qhov siab tshaj plaws ntawm 3000 r / min, lub tshuab xa hluav taws xob tig ntawm 6000 r / min. Vim muaj kev kub ceev ntawm kev sib tsoo tshuab xaws, nws yog ib qho tseem ceeb uas yuav tau xyuam xim tshwj xeeb rau lub tshuab lubrication thaum siv.

Feem ntau cov tshuab xaws siv nyob rau hauv kev lag luam knitwear yog nyob rau hauv qeb no, thiab nws kuj yog ua hauj lwm nyob rau hauv cov tsoos tsho kev lag luam rau overlock tshuab. Qhov tshwj xeeb ntawm cov txheej txheem ib leeg-kov rab koob sib txuas yog tias rab koob nkhaus tsis tsuas yog muaj lub viav vias sab laug tab sis kuj muaj lub viav vias pem hauv ntej-rov qab. Vim tias rab koob nkhaus txav mus rau txhua qhov kev taw qhia yam tsis muaj kev sib cuag nrog lwm lub tshuab, nws muaj kev hnav thiab tsim kua muag tsawg. Yog li ntawd, hom tshuab no feem ntau ua haujlwm ntawm kev kub ceev.

Tag nrho cov tshuab overlock siv hom nuv thiab xov mechanism. Cov txheej txheem hooking yog yooj yim: rab koob loj nkhaus thiab rab koob me me ob lub viav vias sab laug thiab sab xis nyob rau hauv cov qauv crisscross thaum lub sij hawm xov tsim. Zoo li ib rab koob nkhaus, ob rab koob nkhaus tuaj yeem txav mus los hauv qhov chaw raws li cov qauv tshwj xeeb yam tsis tuaj yeem ntsib nrog lwm cov khoom siv tshuab.

Rotary nuv tshuab xaws muaj qhov yooj yim tshaj plaws nuv thiab xov mechanism hauv tshuab xaws. Feem ntau, sab nraud txoj kab uas hla ntawm qhov sib nqus sib nqus yog feem ntau me dua li ib nrab ntawm cov kab sab nraud ntawm lub oscillating shuttle thiab me ntsis loj dua li ib nrab ntawm cov kab sab nraud ntawm lub tshuab xa hluav taws xob. Nyob rau hauv cov txheej txheem hooking no, lub rotary nuv tsis tas yuav dhau los ntawm rab koob; rau txhua lub plooj, lub rotary nuv ua tiav ib qho kev sib hloov tag nrho. Thaum hooking, qhov sib txuas sib txuas tig ntawm nws tus kheej hauv qhov chaw thiab tuaj yeem ua haujlwm ntawm kev kub ceev. Hauv qee lub tshuab lub tshuab uas siv cov koob oscillating thiab siv lub tshuab sib txuas sib txuas sib txuas, rab koob xov loops feem ntau hloov txoj haujlwm vim yog sab laug-txoj cai viav vias ntawm rab koob. Txhawm rau daws qhov teeb meem no, cov cuab yeej sib txawv-ceev crank feem ntau yog siv los xyuas kom meej qhov sib npaug sib npaug ntawm qhov tseeb los ntawm kev tso cai rau nws tig ntawm qhov tsis sib xws hauv ib qho kev sib hloov. Tsis tas li ntawd, thread loop expanders yog ua hauj lwm los xyuas kom meej hooking.
