Ko te mīhini uhi rapa rolerl he taputapu whakauru aunoa mō te takai me te takai rapa i runga i te mata o te roera rapa, e tino whakapai ake ana i te pai o te whakaputa o te wheketere roera rapa i roto i te tukatuka me te hanga hua roera rapa. He taputapu miihini mō te takai me te takai aunoa i te rapa i roto i te tukatuka roera rapa.
1. Whakamāramatanga ingoa
He aha te mīhini takai rapa rolerl? He momo taputapu tēnei mō te hanga moenga rapa, e whakamahi ana i te extruder hei tango i te kiriata o te matotoru me te whānui, ka takai ki te matua o te rakau hurihuri rapa i roto i te huarahi tika me te whakarara. E kore e taea e te mīhini takai rapa roera te whakapai ake i te kounga o te hipoki rapa o ngā moenga rapa, te whakamahi rapa o ngā matotoru rerekē ki ngā matua hurihuri o ngā diameter rerekē, te whakapoto i te wā whakaputa, te whakapai ake i te taumata o te aunoatanga, te whakaiti i te maha o ngā kaiwhakahaere, engari ka whakaoti hoki i te raruraru kāore e taea te whakatutuki i te mīhini me te aunoatanga o ngā taputapu tukatuka nā te koretake o ngā hua me te kanorau o ngā rahi me ngā whakaritenga i roto i te hanga rapa roera. He tirohanga mākete nui me te whakawhirinaki a te kiritaki.
2. Ngā whakaritenga tono
Ko te tukanga whakaputa rōra rapa e toru ngā hononga tukatuka matua: te hanga rōra rapa, te whakamomona rōra rapa, me te maimoatanga mata. He wāhanga tino nui te hononga hanga rōra rapa, arā, ko te tukanga o te hipoki i te matua o te rakau whakarewa ki te rapa. Mena he raruraru kei roto i tēnei hononga, kāore e taea e te rōra rapa i hangaia te whakatutuki i ngā whakaritenga e tumanakohia ana. Nā te whanaketanga o ngā extruders ā-whare, te werohanga werohanga me ētahi atu hangarau, kua āta tīmata te raina whakaputa cots ki te ara o te mīhini me te aunoatanga. Nā ngā whakaritenga rerekē mō ngā cots, kei reira ngā poke, ngā kōhao onepu me ngā mirumiru, kāore e kōrerotia * *, ngā hapa, ngā kapiti me ngā rerekētanga ngohengohe me te pakeke ā-rohe, nō reira kei te tino kaha haere ngā whakaritenga mō te hononga hanga cots. Ko te mahi mākete o te mīhini takai cots e tutuki ana i te kaupapa o te whakatutuki i te oro, Ko te tukanga hanga hipoki rōra rapa katoa e tango ana i te tere ōrite, te kaha paerewa, te takai rapa pumau me ētahi atu mahi, kua riro i te mākete te mōhiotanga me te whakawhirinaki.
3. Te kaupapa mahi
Whakakīia tetahi pito o te matua hurihuri hei paninga ki te pūwero kauae-toru i te pane o te moenga hurihuri o te mīhini takai rōra rapa, ā, ko tetahi pito ka tautokona e te mea kua tāutahia ki te pito o te moenga hurihuri. Ina takaihia te matua hurihuri rapa, tīmatahia te moenga hurihuri i te tuatahi, ā, ka tīmata te neke o te pūwero kauae-toru i roto i te nekehanga porowhita ōrite, i te wā e hurihuri ana te matua hurihuri kua peia. I roto i te tukanga hurihuri tere-iti o te matua hurihuri, tīmatahia te mīhini whakaputa rīpene rapa, ka whakakirikirihia, ka whakaputahia te rīpene rapa āhua ōrite mā te mīhini whakaputa whāngai makariri. Ka haria te rīpene rapa ki te pūnaha takai mā te pūnaha kawe rīpene rapa me te roera ārahi hei tīmata i te takai me te hipoki i te matua hurihuri rapa. Ko te tukanga takai i te matua hurihuri ki te rīpene piri ko te hua o te whakakotahitanga o ngā nekehanga e rua.
Mena ka huri te rīpene rapa me te whānui me te matotoru i te tere pumau huri noa i te tuaka X (tuaka takai rapa) i runga i te mata o te matua takai, ā, ka neke te tikanga takai i te rārangi tika i te tuaka X, ka piri tonu te rīpene rapa ki te matua takai. Ka taea te whakatutuki i te matotoru rerekē o te takai rapa mā te whāngai i te tikanga takai rapa i te tuaka Y (te ahunga porowhita o te takai rapa).
Hei whakatutuki i te matotoru o te paninga e hiahiatia ana mō te takai i te rōra rapa, me whakahaere te matotoru o te takai o te rīpene rapa o te extruder i te tūranga tuaka o te rōra rapa, arā, te nui o te taupatupatu i waenga i te rīpene rapa me te rīpene rapa. Ko te nui o te taupatupatu, ko te matotoru o te takai, ā, ko te iti o te taupatupatu, ko te angiangi o te matotoru o te takai. Ko te tere whakawhiti o te mīhini takai rōra rapa e whakatau tika ana i te rahi o te taupatupatu e pā ana ki te tere hurihuri o te matua rōra.
4. Te hanganga o ngā taputapu
Ko ngā wāhanga matua o te mīhini takai roera rapa PTM ko: te extruder rapa whāngai matao, te tūāpapa hikoi, te taputapu takai, te kawe rīpene rapa, te moenga roera, me te motuka hiko o ngā taputapu e rite ana.
(1) Ko te mīhini whakaputa rapa whāngai makariri te nuinga o te wā e whakamahia ana hei whakarite i ngā rīpene rapa me tētahi āhua pito motuhake mō te hanga takai rapa. Ko tōna āhuatanga ko te taea te whāngai tika i te rapa tāpiri me te kore e whakamahanahia, ā, he nui te rōrahi whakaputa, he iti te pāmahana tukunga, he iti te utu o te rōrahi whakaputa wae, he iti te whakapaunga pūngao, ā, he ōrite, he matotoru hoki ngā rīpene rapa whakaputa.
(2) I te wā e takai ana te takai rapa, me neke te papa haere i roto i te rārangi tika hurihuri i te ahunga porowhita o te matua takai, ā, me whakahaere te nekehanga me te tere o te papa. Ka peia e te motuka servo me te taraiwa servo me te tere tere me te tika o te whakahaere.
(3) Ko te taputapu takai kāpia te wāhanga matua o te mīhini takai roera rapa. Ehara i te mea ko te matua roera rapa anake e kapi ana, engari ka kapi hoki i te mata pito o te matua roera rapa. Ina neke te taputapu takai i te tuaka o te matua roera ki te mata pito o te matua roera me te tūranga whakawhiti o te tuaka, me huri te roera pēhanga kua tāutahia ki te taputapu takai i te 180 nekehanga kia urutau ki te tūranga whakarara ki te papa paninga hei tīmata i te mahi paninga.
(4) Ko te tikanga kawe rīpene piri he whakarerekē i te ahunga kawe o te rīpene piri ina huri te mata tuaka me te tūranga mata pito o te matua hurihuri rapa, ā, ka peka ke, ka taka rānei te rīpene piri. E hiahiatia ana te tikanga kawe rīpene piri kia kore e taea te kawe i te rīpene piri anake, engari kia whakatikatikaina hoki te tūranga kia kore ai e peka ke, e taka rānei te rīpene piri.
(5) He rite te āhua o te moenga roera ki tētahi mīhini hurihuri whakapae noa, ā, ko te nuinga o te mea he turanga, he pane moenga, he tinana moenga, he hiku me te pūnaha tuku. Kua tāutahia he pūwero kauae-toru ki te pane o te moenga, ā, kua tāutahia he pūwero neke ki te pito o te moenga kia māmā ai te piri. Ka whakamahia e te pūnaha tuku he whakaiti wira ngira Baixian, e peia ana e te mekameka. Kua tāpirihia he whāriki whāriki ki te pane moenga me te hiku o te moenga roera, e whakamahia ana hei tautoko i te moenga roera, kia taea ai e te roera rapa whānui te kino i te moenga roera.
