單沖壓片機(ji)的發展
壓(ya)(ya)片(pian)(pian)(pian)機(ji)主要(yao)用于制藥行業的(de)片(pian)(pian)(pian)劑技術研究。壓(ya)(ya)片(pian)(pian)(pian)機(ji)主要(yao)分為(wei)單沖(chong)(chong)壓(ya)(ya)片(pian)(pian)(pian)機(ji)、旋轉壓(ya)(ya)片(pian)(pian)(pian)機(ji)。最早的(de)壓(ya)(ya)片(pian)(pian)(pian)機(ji)是由一(yi)副沖(chong)(chong)模組成的(de)，這臺機(ji)器也(ye)被稱為(wei)單沖(chong)(chong)壓(ya)(ya)片(pian)(pian)(pian)機(ji)。沖(chong)(chong)頭(tou)上下移(yi)動，將粒狀材料壓(ya)(ya)成薄片(pian)(pian)(pian)。
單(dan)沖壓片機性能(neng)優良，具有適應性強，使(shi)用方便，易于維修，體積小，重量輕等(deng)特點。壓(ya)(ya)(ya)片(pian)機裝有一(yi)副沖(chong)(chong)(chong)模(mo)，物料(liao)的充(chong)填(tian)深度，壓(ya)(ya)(ya)片(pian)厚度均可(ke)調節。單(dan)沖(chong)(chong)(chong)壓(ya)(ya)(ya)片(pian)機的下沖(chong)(chong)(chong)的沖(chong)(chong)(chong)頭由(you)中(zhong)模(mo)孔下端進(jin)入(ru)中(zhong)模(mo)孔，封住中(zhong)模(mo)孔底，利用加料(liao)器(qi)向中(zhong)模(mo)孔中(zhong)填(tian)充(chong)藥(yao)(yao)物，上沖(chong)(chong)(chong)的沖(chong)(chong)(chong)頭從中(zhong)模(mo)孔上端進(jin)入(ru)中(zhong)模(mo)孔，并下行一(yi)定距離，將(jiang)藥(yao)(yao)粉壓(ya)(ya)(ya)制成(cheng)片(pian)；隨后上沖(chong)(chong)(chong)上升(sheng)出孔，下沖(chong)(chong)(chong)上升(sheng)將(jiang)藥(yao)(yao)片(pian)頂出中(zhong)模(mo)孔，完成(cheng)一(yi)次壓(ya)(ya)(ya)片(pian)過程；下沖(chong)(chong)(chong)下降到原(yuan)位，準備再一(yi)次填(tian)充(chong)。
根據市(shi)場(chang)行情(qing)來(lai)說，現在的(de)(de)市(shi)場(chang)行情(qing)必須(xu)要打開新的(de)(de)局面，選(xuan)擇(ze)正確(que)的(de)(de)發(fa)展道路(lu)。而隨著市(shi)場(chang)需求的(de)(de)發(fa)展，壓(ya)片機的(de)(de)應用(yong)越(yue)來(lai)越(yue)廣泛(fan)。它不(bu)再局限于壓(ya)制中西藥片，還可以廣泛(fan)應用(yong)于奶片、糖果片、泡(pao)騰片、咀(ju)嚼片、調味塊、消(xiao)毒片、催化劑、化肥片、電子(zi)元件、冶金粉末陶(tao)瓷粒等，而且也適用(yong)于制藥、保健品、食品、農業、化工、電子(zi)電池、冶金陶(tao)瓷等行業生產及(ji)實驗用(yong)。所以，單沖壓(ya)片機產品必須(xu)要根據消(xiao)費者(zhe)的(de)(de)需求來(lai)選(xuan)擇(ze)正確(que)的(de)(de)發(fa)展道路(lu)。
同時(shi)旋轉(zhuan)式壓片(pian)機也開始(shi)誕生。壓片(pian)機同時(shi)上下按壓，使藥物顆粒中的空氣有(you)足夠的時(shi)間(jian)溢出觸(chu)摸(mo)孔，提高(gao)了片(pian)劑密度(du)的均勻(yun)性，減少(shao)了碎(sui)裂現象。旋轉(zhuan)壓片(pian)機還具有(you)振動小、噪音(yin)低、能耗低、效率高(gao)、重(zhong)量(liang)準確(que)等(deng)優點。
