PVC管材生產線(xian)詳細介紹：

原料混合：是(shi)將PVC穩(wen)定(ding)劑(ji)、增塑劑(ji)、化劑(ji)等其它輔(fu)料，按比(bi)例、 工(gong)藝先后(hou)加(jia)入(ru)高速(su)混合機內，經物料與機械自摩擦使物料升溫(wen)至設(she)定(ding)工(gong)藝溫(wen)度，然后(hou)經冷混機將物料降至40-50度；這樣就可以加(jia)入(ru)到擠出(chu)機的(de)料斗。

擠出機部分：由于(yu)pvc管(guan)材設備(bei)錐形螺(luo)桿的(de)(de)(de)特點，加料段具有較大(da)的(de)(de)(de)直(zhi)徑，對物料的(de)(de)(de)傳(chuan)熱(re)面積(ji)和(he)剪(jian)切(qie)速度(du)(du)(du)比較大(da)，有利(li)于(yu)物料的(de)(de)(de)塑化(hua)(hua)，計量段螺(luo)桿直(zhi)徑小，減(jian)少了(le)傳(chuan)熱(re)面積(ji)和(he)對熔(rong)體(ti)(ti)的(de)(de)(de)剪(jian)切(qie)速度(du)(du)(du)，使(shi)熔(rong)體(ti)(ti)能在較低(di)的(de)(de)(de)溫度(du)(du)(du)下擠出。螺(luo)桿在機筒(tong)內旋(xuan)轉時，將PVC混(hun)(hun)合料塑化(hua)(hua)后推向機頭，從而達到壓(ya)實、熔(rong)融、混(hun)(hun)煉均化(hua)(hua)；并(bing)實現排(pai)氣、脫水之目的(de)(de)(de)。

擠出(chu)(chu)模頭部(bu)分：擠出(chu)(chu)模頭是管(guan)(guan)材(cai)成(cheng)型(xing)的(de)主要關鍵部(bu)件，本(ben)pvc管(guan)(guan)材(cai)生(sheng)產線擠出(chu)(chu)模具(ju)由(you)青(qing)島科豐源(yuan)塑料(liao)機(ji)械(xie)有限公司設計，定型(xing)好，生(sheng)產的(de)管(guan)(guan)材(cai)質(zhi)量高。

真(zhen)空定型水(shui)(shui)(shui)箱(xiang)：用于管材(cai)的定型、冷(leng)(leng)卻， 真(zhen)空定型水(shui)(shui)(shui)箱(xiang)上(shang)裝有供定型和冷(leng)(leng)卻的真(zhen)空系統和水(shui)(shui)(shui)循環系統，不(bu)銹(xiu)鋼箱(xiang)體，pvc穿線管材(cai)設備，循環水(shui)(shui)(shui)噴淋冷(leng)(leng)卻， 真(zhen)空定型水(shui)(shui)(shui)箱(xiang)上(shang)裝有前(qian)后(hou)移動(dong)(dong)裝置和左右、高(gao)低調節手(shou)動(dong)(dong)裝置。

牽引機用于連續、自動地將已(yi)冷卻變硬的管材從機頭處引出來，變頻調(diao)速(su)。

切(qie)(qie)割(ge)(ge)(ge)(ge)機：由(you)行(xing)程(cheng)開關根據要求長(chang)度控制后，進行(xing)自動(dong)切(qie)(qie)割(ge)(ge)(ge)(ge)，并翻架，實(shi)行(xing)流水(shui)生產，pvc排水(shui)管(guan)材設備，切(qie)(qie)割(ge)(ge)(ge)(ge)機以(yi)定長(chang)工開關信(xin)號(hao)為指(zhi)令(ling)，完成(cheng)切(qie)(qie)割(ge)(ge)(ge)(ge)全(quan)過(guo)程(cheng)，在切(qie)(qie)割(ge)(ge)(ge)(ge)過(guo)程(cheng)中(zhong)與管(guan)材運(yun)行(xing)保持同步，切(qie)(qie)割(ge)(ge)(ge)(ge)過(guo)程(cheng)由(you)電動(dong)和(he)氣動(dong)驅動(dong)完成(cheng)，切(qie)(qie)割(ge)(ge)(ge)(ge)機設有吸塵裝(zhuang)置，將切(qie)(qie)割(ge)(ge)(ge)(ge)產生的碎屑及時吸出，并回收。

翻(fan)(fan)轉卸(xie)料(liao)臺：翻(fan)(fan)轉動(dong)作(zuo)由氣缸通過氣路(lu)控制來實(shi)現(xian)，翻(fan)(fan)轉臺設有一個(ge)限位裝置，當切割鋸切斷管(guan)材(cai)后，管(guan)材(cai)繼續輸(shu)送(song)，經(jing)后，氣缸進入工作(zuo)，實(shi)現(xian)翻(fan)(fan)料(liao)動(dong)作(zuo)，達(da)到卸(xie)料(liao)翻(fan)(fan)轉的目(mu)的。卸(xie)料(liao)后經(jing)數秒自動(dong)復位，等待下(xia)一循(xun)環。
