1. Pib nrog txhua tus txheej txheem ntawm ua ntej- spinning thiab semi{2}} cov khoom tiav
1. For clearing the falling objects, by adjusting the distance between the a036 and a076 dust sticks, the falling object rate is changed from 2.57 percent to 4.43 percent ; for carding the falling objects, the falling object rate can be changed from 5.2 percent by adjusting the distance between the rear belly falling objects. into about 6.5 percent . After adjustment, the hemp rods and hemp skins on the yarn surface are reduced, and the chance of mixing during weaving is also reduced, which can reduce the "triple jump" defect by 20 percent to 30 percent .
2. Rapier looms muaj kev xav tau ntau dua ntawm qhov zoo ntawm cov xov paj thawj, qhov tsawg dua qhov tsis sib xws ntawm ntu ntev, qhov zoo dua. Feem ntau, nws yuav tsum yog 3 feem pua mus rau 4 feem pua, tus nqi sib npaug cv yog 20 feem pua rau 25 feem pua , thiab ib qho xov paj zog cv tus nqi hauv 18 feem pua rau 20 feem pua.
3. Txhim kho qhov zoo ntawm qhov sib koom ua ke, qhov ntev ntawm qhov kawg feem ntau yog 1.5mm 4mm yog qhov zoo tshaj plaws, thiab kev sib koom tes nrog kev sib tw loj yuav tsum tshwj xeeb tshaj yog tiv thaiv los ntawm cov braids me me.
4. Warping requirements ensure "three spirits", that is, flexible rotation of tension ring, flexible braking, flexible automatic stop when broken ends, and at the same time slightly heavier side yarn, so that the tension of the whole warp yarn is uniform.
5. Txhim kho qhov zoo ntawm sizing, txhim kho qhov pom tseeb ntawm warp qhib, tsim nyog xaiv qhov sizing thiab tsim cov sizing tus nqi raws li ntau yam. Feem ntau, qhov sizing tus nqi ntawm hemp paj rwb yog 8 feem pua rau 9 feem pua , uas tuaj yeem txaus siab rau qhov tsim ntawm tus du thiab hnav - resistant sizing zaj duab xis rau saum npoo ntawm warp. Txhawm rau kom tswj tau cov dej noo kom raug, yog tias qhov txheeb ze av noo ntawm lub rhiav rhiav yog siab dua 80 feem pua, cov dej noo rov qab ntawm qhov loj tuaj yeem tswj tau li ntawm 7 mus rau 8 feem pua; qhov elongation ntawm qhov sizing yuav tsum tswj kom tsim nyog, thiab cov ntaub sizing yuav tsum tau tswj hauv qab 1 feem pua; Qhov kev txhim kho yog nyob rau hauv thaj tsam ntawm 10 feem pua mus rau 15 feem pua, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm rapier loom fabrics.
2. Lub sijhawm qhib thiab pub mis yuav tsum sib koom ua ke kom zoo. Feem ntau, muaj ntau txoj hauv kev rau cov xov paj hla qhov tsis xws luag ntawm sab ntawm weft feeder. Yog li ntawd, sib txawv configurations yuav siv tau los kho cov weaving parameters ntawm ob sab. Lub sij hawm pub mis ntawm rab ntaj weft yog qhov tsim nyog, kom rab ntaj weft tuaj yeem nkag mus rau lub qhov ncauj kom meej. Feem ntau hais lus, lub sij hawm qhib ntawm hemp thiab paj rwb ntau yam yuav tsum yog 290 degree -300 degree, thiab rab ntaj pub lub sij hawm yog 70 degree -75 degree. Thaum noj rab ntaj, txoj hauj lwm ntawm lub weft feeding rapier yog 4 mus rau 6 phau ntawv qhia tawm ntawm lub qhov ncauj, thiab txoj hauj lwm ntawm weft txais rapier yog 2 mus rau 20 degrees deb ntawm lub qhov ncauj. 4 txoj kev taw qhia, thiab tseem xyuas kom meej tias rab ntaj nkag mus maj mam thiab rab ntaj tawm sai sai kom rab ntaj muaj sijhawm txaus los hla lub kendo ntshiab thiab txo txoj hauv kev ntawm cov xov paj dhia.
3. Kev hloov kho ntawm txoj haujlwm warp Kho qhov siab ntawm txoj hauj lwm kab, feem ntau tsuas yog kho qhov siab ntawm qhov poob thav duab thiab lub teeb nraub qaum. Thaum lub thav duab poob thiab lub nraub qaum yog tsa, qhov sib txawv ntawm qhov sib txawv ntawm cov xov paj qaum thiab qis dua. Thaum lub weaving poob tag nrho qhib, lub qis warp yarns yog nruj thiab lub Upper warp yarns yog xoob kom lub warp yarns yog sib npaug zos thiab ib tug fuller daim ntaub nto yuav tau. Yog hais tias lub elevator siab dhau lawm, lub qaum warp yarns yog xoob heev, thiab warp yarns lo rau ib leeg, ua rau qhov qhib tsis meej thiab nws yuav ua rau lub hnub qub dhia. Feem ntau, qhov siab ntawm sab nraub qaum ntawm hemp thiab paj rwb ntau yam yog 70mm txog 80mm, qhov siab ntawm qhov poob thav duab yog 30mm txog 40mm, thiab ob qhov kawg yuav tsum tau khaws cia kab rov tav.
Fourth, the correct hanging heald specifications generally control the lower warp yarns to be slightly lower than higher. During the upper shaft and maintenance work, the lifting heald should be adjusted to ensure the "three alignments", that is, the alignment of the heald frame, the alignment of the tread bar, and the alignment of the tread plate and the rotor. "Siping" means that the heald frame (heddle bar) is flat, the lifting bolt is flat, the hanging heald plate is flat, and the stepping heald rod is flat. If it is unqualified, check whether the heald clip falls off, whether the top wire of the tread plate is loose, whether the bearing pad of the hanging heald is worn, whether the hanging heald belt is deformed, etc. Generally, the front and rear positions of the hoisting shaft are about 110mm to 120mm, the movement does not exceed 0.8mm, and the height of the hoisting shaft is 400mm to 410mm. The above measures have been tested on the GA747 loom for weaving 8s8s4238 hemp-cotton plain weave. The efficiency of the loom was increased from 50 percent to 65 percent , and the number of "three-jump" defects was reduced from 500 to about 200 in 90m cloth.
