The isi atụmatụ nkeNanhai YaPlastic Extruder Machine bụ "na-ebuga na-aga n'ihu, plasticizing dị elu na-arụ ọrụ nke ọma, yana ịkpụzi kwụsiri ike."
The extruder nwere usoro isi ise site na nri ruo na ịkpụzi, nke ọ bụla nwere ọrụ akọwapụtara nke ọma ma na-arụkọ ọrụ ọnụ:
1. Sistemụ nri
Isi ihe: hopper, feeder (kewara n'ime nri ike ndọda na inye nri mmanye).
Ọrụ: Na-ebufe granules plastik siri ike / ntụ ntụ gaa na ngalaba nri screw, na-ezere "njikọ" (ihe mgbochi ihe na hopper). Ndị na-eri nri na-amanye (dị ka ndị na-eji ejima-screw feeders) kwesịrị ekwesị maka ihe ndị dị elu ma ọ bụ ngwa ngwa ngwa ngwa, yana nri ziri ezi nke ± 1%.
2. Plasticizing System
Isi ihe: ịghasa, gbọmgbọm, kpo oku na ngwaọrụ jụrụ oyi.
Ọrụ: Isi ebe maka "ntụgharị mmiri siri ike" nke plastik. Ntugharị ihe nkedo na-emepụta ike shear, nke jikọtara ya na kpo oku nke gbọmgbọm (na-abụkarị akụkụ 3-5), jiri nwayọọ nwayọọ na-agbaze ma gbazee plastik siri ike; ngwaọrụ jụrụ oyi (dị ka mmiri jụrụ oyi ma ọ bụ ikuku jụrụ oyi) na-achịkwa okpomọkụ gbọmgbọm iji gbochie ikpo oke ọkụ na mmebi nke ihe.
Akụkụ ndị dị mkpa: Ogo nke ịghasa ogologo-ruo dayameta (L/D) na-abụkarị 20:1-30:1. The gbọmgbọm kpo oku okpomọkụ na-gbanwee dị ka plastic ihe (e.g., PE 180-220 ℃, PVC 160-190 ℃).
3. Usoro nnyefe
Isi ihe: moto, gearbox, njikọ.
Ọrụ: Na-enye ike kwụsiri ike na ịghasa ma na-achịkwa ọsọ nke ịghasa (na-abụkarị 10-100 r / min). Moto na-ejikarị moto na-agbanwe agbanwe ma ọ bụ servo moto, na-enye ohere maka mmezi ọsọ ọsọ; igbe gear na-ebelata ọsọ moto ma na-abawanye torque iji gboo mkpa ọrụ dị elu nke ịghasa.
4. anwụ Isi na ebu System
Isi ihe: Die isi (jikọọ gbọmgbọm na ebu), ebu (na-ekpebi cross-section udi nke ngwaahịa).
Ọrụ: Na-ewebata plastik a wụrụ awụ n'ime oghere akpụ akpụ wee wepụ ya n'ụdị dị iche iche (dịka, ọkpọkọ, mpempe akwụkwọ, profaịlụ). Ọ dị mkpa ka a rụzie ihe akpụ akpụ nke ọma dịka akụkụ ngwaahịa si dị. Ụdị ndị a na-emekarị na-agụnye ọkpụkpụ ọkpọkọ, ihe ndị dị larịị (ibé akwụkwọ/ihe nkiri), na ihe ndị na-adịghị agbanwe agbanwe (profaịlụ ọnụ ụzọ na windo).
5. Ịkpụzi, Ntugharị, na Traction System
Ihe ndị bụ isi: Aka aka na-akpụzi (dịka, oghere sizing sleeve, calendering roller), tankị jụrụ oyi (mmiri jụrụ oyi / ikuku jụrụ oyi), igwe traktị.
Ọrụ: Ngwa ngwa na-eme ka ọ dị jụụ ma na-akpụzi profaịlụ okpomọkụ dị elu nke extruded, ebe n'otu oge na-adọta ya na ọsọ ọsọ site na igwe traction iji hụ na nkwụsi ike nke ngwaahịa ahụ (dịka ọmụmaatụ, ọkpọkọ mgbidi mgbidi ≤ ± 0.1mm). Ọsọ traction ga-adakọrịrị na ọsọ extrusion iji gbochie ndọtị ngwaahịa ma ọ bụ wrinkling.
Dabere na mmepụta chọrọ, anyị nwere ike inyeotu-ịghasa extruders, ejima-ịghasa extruders, na extrusion mmepụta ahịrị.
