Wolemba: Smartweigh-Multihead Weighter
Multihead weigher ndi sensor yamadzimadzi yokoka, yomwe imakhala yodziwika kwambiri pakuyezetsa kolondola kwamtundu wa data ndikuyezetsa kolondola. 1. Tanthauzo la weigher wa ma multihead weigher amaganizira za kuwonongeka kwa mphamvu yokoka (g) ndi kukwera kwa nthunzi (f) pogwiritsa ntchito adiresi yatsatanetsatane, ndipo zimachokera pakusintha chimodzi mwazopimidwa molondola (misa) kukhala chinacho Muyeso wolondola (zotuluka). ) Kachipangizo ka mphamvu kuti muyezedwe bwino misa. 2. Zinthu zofunika za multihead weigher Polyurethane chuma Polyurethane elastomer (kugwedera wodzipatula, tcheru mtengo) kumabweretsa mapindikidwe zotanuka pansi pa zochita za mphamvu yakunja, kotero kuti kukana mavuto n'zotsimikizira (kutembenuka kwamagetsi chipangizo) anaika pamwamba pake kumabweretsa mapindikidwe. , kukana Pambuyo pa kusweka kwa strain gauge, kukana kwake kumapangitsa kusintha (kuwonjezeka kapena kuchepa), ndiyeno kusintha kwa kukana kumeneku kudzasinthidwa kukhala chizindikiro cha deta cha chipangizo chamagetsi kupyolera mu dera loyezera molondola, motero kukwaniritsa kusintha kwa deta. mphamvu yakunja mu chizindikiro cha deta cha chipangizo chamagetsi. ndondomeko yonse.
Zitha kuwoneka kuti kukana kupsinjika, gauge ya polyurethane zinthu polyurethane elastomer ndi dera lodziwikiratu ndi magawo angapo ofunikira omwe sangathe kusowa muyeso yolimbana ndi kukana kwamtundu wa multihead weigher. Mbali zitatuzi zikukambidwa mwachidule pansipa. 1. Resistance strain gauge The resistant strain gauge ndi gawo la kukana kuwunika komwe kumayatsira zida zamafakitale zama waya pakhoma kapena zinthu zopangidwa ndi organic.
Chimodzi mwazofunikira zake zofunika kwambiri ndi chenjezo lolozera mtengo wa K. Pamene mbali zake ziwiri zimagonjetsedwa ndi mphamvu ya F, zikhoza kugwedezeka ndi kutambasula, ndiko kunena kuti chifukwa cha deformation. Kungoganiza kuti kusinthasintha kwake ndi kufalikira, malo ake ozungulira amachepetsedwa, ndiko kuti, chigawo chake chozungulira chozungulira chimachepetsedwa.
Resistivity elasticity coefficient (kusintha kofananira kwa kukana) kwa choyezera chazovuta komanso mphamvu yamphamvu (kusintha kofananira kwa kutalika) kwa waya wotenthetsera zimagwirizana bwino ndi kuchuluka kwa okhalamo. Tiyenera kudziwa kuti tsatanetsatane wa mtengo wa sensitivity index mtengo wa K ndi gawo lomwe limayendetsedwa ndikusankhidwa ndi mawonekedwe azinthu zopangira kupanga waya wopangira zitsulo. Zilibe kanthu kochita ndi maonekedwe, mawonekedwe, chitsanzo ndi ndondomeko ya kukana kutsutsa. Mtengo wake nthawi zambiri ndi 1.7—3.6 Pakati; chachiwiri, mtengo wa K ndi kuchuluka kopanda dimensionless, ndiye kuti, alibe dimension. Mu maziko a makina, ΔL / L imatchedwa chiweruzo, chomwe chimatchedwa ε, ndipo chimagwiritsidwa ntchito kusonyeza kuti pulasitiki nthawi zambiri imawoneka ngati yaikulu kwambiri, yomwe imakhala yovuta kwambiri, ndipo imodzi mwa milioni imodzi imagwiritsidwa ntchito ngati kampani, yomwe imatchulidwa kuti. με.
2. Polyurethane elastomer Polyurethane elastomer polyurethane elastomer ndi chigawo ndi maonekedwe osiyana. Lili ndi ntchito ziwiri. Pachiyambi, imakhala ndi udindo wa mphamvu yakunja yomwe imavutika ndi choyezera chamitundu yambiri, ndipo mphamvu yakunja imayambitsa mphamvu yochitirapo kanthu kuti iwonetsetse kufanana; Kukaniza strain gauge ndikoyenera kuchita ntchito ya tsiku ndi tsiku ya kutembenuka kwa chizindikiro cha data cha chipangizo chamagetsi. 3. Detection circuit Ntchito ya chigawo chodziwikiratu ndikusintha kusintha kwa kukana kwa strain gauge kuti ikhale yogwira ntchito.
Chifukwa mlatho wa Wheatstone uli ndi ubwino wambiri, monga momwe umatha kupondereza kuwonongeka kwa kusintha kwa kutentha, ukhoza kupondereza kuwonongeka kwa mphamvu ya mbali, ndipo ukhoza kuthetsa vuto la malipiro a multihead weigher mosavuta komanso mofulumira, kotero kuti mlatho wa Wheatstone wapezeka mu multihead weigher. Ntchito zosiyanasiyana. Chifukwa cha kukhudzidwa kwakukulu kwa dera la unyolo wodzaza ndi milatho yodzaza ndi manja, magawo oyambira a mkono uliwonse ndi ofanana, ndipo zoopsa zosiyanasiyana zimatha kusokonezana. dera.
