使水龍頭4出來的水淋在上層槽2a的前側(cè)板上并分別濺入上層槽2a和連通槽2c，從而實現(xiàn)冷卻水的循環(huán)利用。水龍頭4在焊條進(jìn)入上層槽2a的前方位置處進(jìn)行噴淋冷卻水，提前對焊條進(jìn)行預(yù)冷卻，同時在焊條進(jìn)入上層槽2a后再次進(jìn)行噴淋冷卻水，能有效防止焊條驟冷變形。比較好是，上層槽2a的前壁頂部設(shè)置有高于焊條過孔2b的溢水缺口2d，上層槽2a的冷卻水還能經(jīng)溢水缺口2d流入連通槽2c。另外，連通槽2c的橫截面呈三角形，以騰出空間使焊條從連通槽2c的上方通過。自動切斷機構(gòu)c，主要由工作臺12、安裝架13、立塊14、焊條導(dǎo)向管15、“門”形安裝架16、豎直氣缸6、焊條切斷刀7、螺栓8、上導(dǎo)向膠輪9和下導(dǎo)向膠輪10、限位柱11組成。工作臺12上安裝有上導(dǎo)向膠輪9和下導(dǎo)向膠輪10。上導(dǎo)向膠輪9和下導(dǎo)向膠輪10的中部分別設(shè)置有環(huán)向缺槽，且兩個環(huán)向凹槽正好圍成供橫截面為等邊三角形的焊條通過的通道，上導(dǎo)向膠輪9和下導(dǎo)向膠輪10轉(zhuǎn)動的同時，帶動焊條向后移動。在通道的正前方設(shè)置有左、右兩根限位柱11，供焊條從中穿過，左、右限位柱11通過“l(fā)”形板安裝到工作臺12上。工作臺12的后壁上安裝有安裝架13，安裝架13呈“7”字形并朝向后方。安裝架13的這種安裝方式，是為了讓切斷后的焊條能自動下落。</p><p> 本實用新型涉及一種用于制造防腐罐焊條的自動生產(chǎn)線。背景技術(shù)：防腐罐本體為pph聚丙烯材質(zhì)，采用pph聚丙烯的焊條焊接成型，焊條橫截面為等邊三角形。防腐罐焊條通過塑料擠出機制作，焊條經(jīng)塑料擠出機成型后再人工剪切成條。但是塑料擠出機出來的焊條溫度較高，人工剪切不便于握持，且對尚未降溫的焊條進(jìn)行剪切易造成焊條變形；但若不及時進(jìn)行剪切，源源不斷出來的焊條又無處放置。技術(shù)實現(xiàn)要素：本實用新型旨在提供一種防腐罐焊條的自動生產(chǎn)線，能對塑料擠出機出來的pph聚丙烯焊條進(jìn)行及時冷卻及自動剪切成條，并確保焊條質(zhì)量。為此，本實用新型所采用的技術(shù)方案為：一種防腐罐用焊條自動生產(chǎn)設(shè)備，包括塑料擠出機，還包括水冷循環(huán)系統(tǒng)和自動切斷機構(gòu)，三者從前到后依次布置；所述水冷循環(huán)系統(tǒng)包括機架，所述機架上方設(shè)置有長條形的水槽，所述水槽由水平隔板分割成敞開的上層槽和封閉的下層槽，在水槽的兩端設(shè)置有連通槽，所述上層槽的前壁、后壁上對應(yīng)開設(shè)有焊條過孔，且焊條過孔的直徑為等邊三角形焊條邊長的兩倍到三倍之間，在上層槽內(nèi)前后間隔安裝有至少兩根水平設(shè)置的焊條導(dǎo)向桿，且焊條過孔、焊條導(dǎo)向桿在高度上齊平，所述上層槽的冷卻水能經(jīng)焊條過孔流入連通槽。在埋弧焊、電渣焊和其他熔化極氣體保護(hù)電弧焊時，焊絲既是填充金屬，同時焊絲也是導(dǎo)電電極。</p><div
