Lub tshuab slitting tuaj yeem muab faib ua peb txoj hauv kev hauv cov txheej txheem slitting: tiaj riam slitting, puag ncig riam slitting, extrusion slitting
1. Cov riam slitting
Ib yam li rab chais, lub tshuab slitting kho cov hniav ib leeg los yog ob sab ntawm cov hniav ntawm ib rab riam ruaj, thiab tee cov riam thaum lub sij hawm cov khoom khiav, kom cov riam txiav cov khoom longitudinally kom tiav lub hom phiaj ntawm slitting.
Muaj ob txoj hauv kev ntawm rab chais slicing:
Ib qho yog grooving thiab slitting; lwm qhov yog suspended slitting.
Grooving thiab slitting txhais tau hais tias thaum cov khoom siv khiav ntawm cov grooved cov menyuam, cov riam txiav tau poob rau hauv qhov zawj ntawm cov menyuam grooved txiav cov khoom longitudinally. Lub sijhawm no, cov khoom siv muaj qee qhov qhwv lub kaum sab xis ntawm cov menyuam grooved, uas tsis yooj yim rau drift. Thaum slitting cam khwb cia PP zaj duab xis lossis zaj duab xis nrog cov khoom nqaim, txoj kev slitting no feem ntau siv, uas tuaj yeem txhim kho kev ua haujlwm ntawm lub tshuab slitting. Tab sis rau kev tshem tawm slitting, nws qhov tsis zoo yog tias nws tsis yooj yim los teeb lub riam.
Suspension slitting txhais tau hais tias thaum cov khoom hla nruab nrab ntawm ob lub chais, rab chais ntog los txiav cov khoom longitudinally. Lub sijhawm no, cov khoom siv nyob rau hauv lub xeev tsis ruaj khov, yog li qhov tseeb slitting yog me ntsis phem dua li ntawm kev txiav tuag, tab sis hom slitting Cov txheej txheem no yooj yim rau kev teeb tsa thiab yooj yim rau kev khiav lag luam. Flat cutter slitting yog tsim rau slitting heev nyias yas zaj duab xis thiab puas zaj duab xis.
2. Round riam txiav
Round riam slitting tuaj yeem muab faib ua tangential slitting thiab non-tangential slitting.
Tangential slitting txhais tau hais tias cov khoom raug txiav los ntawm tangential kev taw qhia ntawm sab sauv thiab sab disc riam. Hom slitting no yooj yim dua rau kev sib tw riam. Cov riam sab sauv thiab cov riam qis dua tuaj yeem hloov kho tau yooj yim raws li kev txiav dav. Nws qhov tsis zoo yog tias cov khoom siv yooj yim txav ntawm qhov chaw txiav, yog li qhov tseeb tsis siab, thiab nws feem ntau tsis siv tam sim no.
Non-tangential slitting txhais tau hais tias cov khoom siv thiab cov riam qis dua muaj lub kaum ntse ntse qhwv, thiab cov riam qis qis poob los txiav cov khoom. Txoj kev txiav ntawm lub tshuab slitting tuaj yeem ua rau cov khoom tsis tshua muaj kev sib tw, thiab txiav precision siab. Tab sis nws tsis yooj yim heev los kho cov riam. Thaum txhim kho lub hauv qab disc riam, tag nrho cov ncej yuav tsum tau muab tshem tawm. Round riam slitting yog tsim rau slitting thicker composite films thiab ntawv.
3. Extrusion thiab txiav
Extrusion slitting yog tsis muaj nyob rau hauv domestic slitting tshuab. Nws yog tsuas yog tsim los ntawm cov menyuam hauv qab uas yog synchronized nrog cov ntaub ntawv ceev thiab muaj qee qhov qhwv lub kaum ntse ntse nrog cov khoom siv, thiab cov riam pneumatic uas yooj yim kho. Txoj kev txiav no tuaj yeem tsis tsuas yog txiav cov yas nyias nyias, tab sis kuj txiav cov ntawv tuab, cov ntaub tsis-woven, thiab lwm yam. Nws yog txoj hauv kev yooj yim dua ntawm kev txiav. Nws yog txoj kev loj hlob ntawm kev siv tshuab slitting tshuab slitting.
