Lub tshuab knotless net tau taug kev ntev txoj kev los ntawm tes- pab looms thiab mechanical raschel thav duab rau PLC niaj hnub no - tswj extrusion thiab warp -knitting kab. Lub tshuab knotless net niaj hnub no tsis tsuas yog "weaves tsis muaj pob" - nws fuses polymer science, servo motion control, thiab inline zoo soj ntsuam rau hauv ib tug tas mus li txheej txheem. Kev taug qab qhov kev hloov pauv no piav qhia vim li cas niaj hnub no cov nets tsis muaj zog muaj zog dua, huv dua, thiab muaj ntau yam ntau dua li cov uas tau ua txawm nees nkaum xyoo dhau los.
Tshooj ntxov tshaj plaws yog nyob rau sab textile. Kev nuv ntses thiab ua liaj ua teb nets tau knotted, uas tsim cov ntsiab lus tsis muaj zog thiab khib nyiab. Nyob rau hauv nruab nrab- xyoo pua 20th, Raschel warp-knitting tshuab tau hloov kho los tsim cov ntses tsis muaj ntses los ntawm nylon thiab polyamide yarns, tshem tawm cov pob caus tag nrho thiab muab cov xov paj zoo dua, zoo dua qub. Cov qauv knotless net thaum ntxov no tau tsav los ntawm mechanically, cam- tswj, thiab txwv rau cov qauv mesh yooj yim-tab sis lawv tau ua pov thawj qhov txiaj ntsig zoo: cov khoom siv tsawg dua, muaj zog dua, thiab cov zis tawm sai dua li knotted netting.
Ua tib zoo rau qhov no, xyoo 1950 tau coj qhov kev ua tiav thib ob: extrusion-raws li yas netting. Dr. Mercer's 1955 invention of extruded plastic mesh cia lub tshuab knotless net form tubular los yog ca PE / PP net ncaj qha los ntawm molten polymer, tsis muaj xov paj, tsis muaj loom, tsis muaj knots. Cov tshuab extrusion thaum ntxov yog crude-ib zaug-theem screws, phau ntawv hloov pauv, cov dej da dej yooj yim-tsis tau lawv qhib lub qhov rooj rau txiv hmab txiv ntoo tes tsho, pallet nets, thiab industrial mesh ntawm industrial scale.
Qhov kev hloov pauv tiag tiag tuaj nrog tswj hluav taws xob. Qhov twg cov tshuab xyoo 1980 tau tso siab rau cov qauv kev sib txuas thiab phau ntawv tensioning, niaj hnub no knotless net tshuab siv PLC controllers, touchscreen HMI, servo- tsav tsheb qhia tuav, thiab hluav taws xob nqa- nce. Raschel- hom tshuab tam sim no muaj 6-8 cov ntawv qhia hluav taws xob, pib- xov paj- pub, laser tawg detectors, thiab qauv cia- cia cov neeg ua haujlwm hloov mesh geometry hauv feeb es tsis txhob rov tsim lub cam box. Extrusion- hom tshuab tau txais PID qhov kub thiab txias zoning, servo haul-offs, tus kheej- ntxuav dies, thiab optical strand- tshuaj xyuas, tuav mesh kam rau ua nyob rau hauv ± 3% ntawm 45 m / min.
Cov khoom yooj yooj yim yog lwm qhov leap. Lub tshuab knotless tam sim no tuav HDPE, PP, nylon, rov siv dua granulate, thiab txawm tias PLA biodegradable blends los ntawm swapping ntsia hlau compression piv thiab txo qis extrusion kub rau bio-polymers. Qhov ntawd ncaj qha teb cov lus samfwm kev ruaj ntseg niaj hnub no -ib yam dab tsi ua tsis tau ntawm cov qub qub - cov khoom siv tshuab.
Thaum kawg, ciam teb ntawm ob tsev neeg yog qhov muag plooj. Cov nroj tsuag niaj hnub no khiav cov kab sib txuas uas extruded tubular mesh yog inline txiav, kaw, lossis knit- ntxiv dag zog, tag nrho hauv ib PLC. Kev saib xyuas kev kwv yees, kev ntsuas lub zog, thiab daim ntawv qhia rov qab yog tam sim no cov ntsiab lus muag khoom rau txhua tus neeg siv khoom loj knotless net.
Nyob rau hauv luv luv, lub knotless net tshuab evolved los ntawm mechanical raschel thav duab thiab rudimentary extruders rau hauv digitally tswj, khoom siv - yoog raws, tshuaj xyuas - nruab cov tshuab tsim khoom. Txhua tiam tau tshem tawm ib lub raj mis-Knots, phau ntawv hloov qauv, thermal drift, ib zaug - cov ntaub ntawv txwv- thiab cov tiam tom ntej twb tau mus rau AI -tuned extrusion thiab xoom- khib nyiab net forming.
