弛(chi)張(zhang)(zhang)篩(shai)(shai)(shai)(shai)(shai)是(shi)(shi)我(wo)廠生(sheng)(sheng)產(chan)的(de)(de)(de)(de)(de)一(yi)(yi)種新(xin)型篩(shai)(shai)(shai)(shai)(shai)分(fen)機(ji)械(xie)。該機(ji)采用(yong)雙質(zhi)體亞共振(zhen)(zhen)(zhen)原理(li)，通過(guo)傾斜篩(shai)(shai)(shai)(shai)(shai)箱(xiang)上(shang)安裝(zhuang)的(de)(de)(de)(de)(de)彈性(xing)(xing)(xing)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)弛(chi)、張(zhang)(zhang)運(yun)(yun)動(dong)拋擲物(wu)料(liao)的(de)(de)(de)(de)(de)篩(shai)(shai)(shai)(shai)(shai)分(fen)機(ji)。其(qi)主要特(te)點(dian)是(shi)(shi)篩(shai)(shai)(shai)(shai)(shai)分(fen)效(xiao)率(lv)提高，處理(li)量(liang)大(da)，動(dong)負荷小，功耗少(shao)，噪聲低(di)，因此應(ying)用(yong)較(jiao)(jiao)為廣泛(fan)。在(zai)這個(ge)(ge)過(guo)程中(zhong)，彈性(xing)(xing)(xing)聚氨酯篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)以每分(fen)鐘(zhong)800次的(de)(de)(de)(de)(de)頻率(lv)連(lian)續不(bu)斷地擴(kuo)張(zhang)(zhang)、收縮，從而(er)獲得(de)很高的(de)(de)(de)(de)(de)加速度（50g），可處理(li)6mm以下(xia)的(de)(de)(de)(de)(de)粘(zhan)性(xing)(xing)(xing)難篩(shai)(shai)(shai)(shai)(shai)分(fen)的(de)(de)(de)(de)(de)物(wu)料(liao)，采用(yong)獨特(te)的(de)(de)(de)(de)(de)雙重(zhong)振(zhen)(zhen)(zhen)動(dong)原理(li)，即(ji)通過(guo)共振(zhen)(zhen)(zhen)幫助(zhu)，使(shi)(shi)(shi)一(yi)(yi)個(ge)(ge)基本(ben)橢圓振(zhen)(zhen)(zhen)動(dong)帶(dai)動(dong)了(le)(le)(le)其(qi)他的(de)(de)(de)(de)(de)一(yi)(yi)層(ceng)(ceng)(ceng)或多層(ceng)(ceng)(ceng)的(de)(de)(de)(de)(de)浮(fu)床曲張(zhang)(zhang)，并且浮(fu)床曲張(zhang)(zhang)振(zhen)(zhen)(zhen)動(dong)的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)幅遠大(da)于傳統的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)動(dong)設(she)備(bei)的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)幅，有效(xiao)地防止了(le)(le)(le)篩(shai)(shai)(shai)(shai)(shai)孔(kong)堵塞(sai)(sai)(sai)。弛(chi)張(zhang)(zhang)篩(shai)(shai)(shai)(shai)(shai)是(shi)(shi)雙質(zhi)量(liang)振(zhen)(zhen)(zhen)動(dong)系(xi)統，采用(yong)聚氨酚橡膠篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)，支(zhi)承篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)任意兩(liang)根相(xiang)(xiang)鄰橫梁都分(fen)別(bie)屬于兩(liang)個(ge)(ge)振(zhen)(zhen)(zhen)動(dong)質(zhi)體，其(qi)中(zhong)一(yi)(yi)個(ge)(ge)質(zhi)體是(shi)(shi)篩(shai)(shai)(shai)(shai)(shai)箱(xiang)，另一(yi)(yi)個(ge)(ge)質(zhi)體是(shi)(shi)配(pei)重(zhong)。在(zai)工作時(shi)，篩(shai)(shai)(shai)(shai)(shai)網(wang)交替地拉緊和松(song)弛(chi)，使(shi)(shi)(shi)物(wu)料(liao)產(chan)生(sheng)(sheng)前進彈跳運(yun)(yun)動(dong)，可避免(mian)物(wu)料(liao)黏附篩(shai)(shai)(shai)(shai)(shai)網(wang)并堵塞(sai)(sai)(sai)篩(shai)(shai)(shai)(shai)(shai)孔(kong)。當(dang)兩(liang)質(zhi)體相(xiang)(xiang)差二相(xiang)(xiang)位振(zhen)(zhen)(zhen)動(dong)時(shi)，任意兩(liang)根相(xiang)(xiang)鄰橫梁時(shi)而(er)靠近，時(shi)而(er)遠離，彈性(xing)(xing)(xing)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)也相(xiang)(xiang)應(ying)時(shi)而(er)松(song)弛(chi)，時(shi)而(er)張(zhang)(zhang)緊，即(ji)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)隨篩(shai)(shai)(shai)(shai)(shai)箱(xiang)作牽連(lian)運(yun)(yun)動(dong)的(de)(de)(de)(de)(de)同時(shi)，還相(xiang)(xiang)對篩(shai)(shai)(shai)(shai)(shai)箱(xiang)作相(xiang)(xiang)對運(yun)(yun)動(dong)。這種弛(chi)張(zhang)(zhang)運(yun)(yun)動(dong)不(bu)僅使(shi)(shi)(shi)篩(shai)(shai)(shai)(shai)(shai)孔(kong)不(bu)斷產(chan)生(sheng)(sheng)變形，而(er)且大(da)大(da)增加了(le)(le)(le)篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)動(dong)強(qiang)度，從而(er)有效(xiao)地克服了(le)(le)(le)篩(shai)(shai)(shai)(shai)(shai)孔(kong)堵塞(sai)(sai)(sai)現象(xiang)，顯著提高了(le)(le)(le)篩(shai)(shai)(shai)(shai)(shai)機(ji)處理(li)能力。但是(shi)(shi)因篩(shai)(shai)(shai)(shai)(shai)箱(xiang)的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)動(dong)強(qiang)度并不(bu)大(da)，故機(ji)械(xie)強(qiang)度容易保證(zheng)，但篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)(de)(de)(de)(de)振(zhen)(zhen)(zhen)動(dong)強(qiang)度較(jiao)(jiao)大(da)且反復變形，故篩(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)壽命較(jiao)(jiao)低(di)。根據料(liao)群運(yun)(yun)動(dong)自身規律性(xing)(xing)(xing)，鵬威弛(chi)張(zhang)(zhang)篩(shai)(shai)(shai)(shai)(shai)可有效(xiao)的(de)(de)(de)(de)(de)使(shi)(shi)(shi)濕(shi)粘(zhan)物(wu)料(liao)層(ceng)(ceng)(ceng)松(song)散、分(fen)層(ceng)(ceng)(ceng)和透篩(shai)(shai)(shai)(shai)(shai)。
