單板烘干機是單板和膠合板生產過程中的主要設備之一。單板干燥質量的好壞直接影響到單板和膠合板產品的質量，也直接影響到輥壓式連續單板干燥機的(de)(de)設(she)計。其主要工作原(yuan)理是在上下(xia)鋼帶(dai)夾緊的(de)(de)情(qing)況下(xia)，用預(yu)熱(re)管(guan)預(yu)熱(re)單(dan)板，鋼帶(dai)與單(dan)板的(de)(de)溫度趨于(yu)一致。

  然后在干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)滾筒(tong)之(zhi)間(jian)快(kuai)速(su)干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)，使單板(ban)(ban)(ban)(ban)(ban)干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)后光(guang)滑(hua)，含水率均(jun)勻，可大(da)(da)大(da)(da)提高干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)質(zhi)量和干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)效率。它具有(you)高溫滾筒(tong)與濕單板(ban)(ban)(ban)(ban)(ban)直(zhi)接接觸傳(chuan)熱(re)(re)、熱(re)(re)效率高、熱(re)(re)損(sun)失(shi)小的(de)特點，大(da)(da)大(da)(da)降低了熱(re)(re)損(sun)失(shi)。2.干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)系統采(cai)用更(geng)科學的(de)干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)原理。熱(re)(re)風(feng)爐內(nei)的(de)熱(re)(re)風(feng)通(tong)過離心式風(feng)扇直(zhi)接注(zhu)入機器的(de)上(shang)下(xia)波紋管(guan)，熱(re)(re)風(feng)通(tong)過上(shang)、下(xia)波紋管(guan)的(de)噴(pen)嘴吹到單板(ban)(ban)(ban)(ban)(ban)的(de)上(shang)、下(xia)兩(liang)面。單板(ban)(ban)(ban)(ban)(ban)加熱(re)(re)均(jun)勻，以(yi)便干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)。3.刨單板(ban)(ban)(ban)(ban)(ban)驅動(dong)系統通(tong)過進料口縱(zong)向(xiang)進給機器，鏈條驅動(dong)上(shang)、下(xia)兩(liang)排滾子(zi)，相(xiang)對(dui)運行。單板(ban)(ban)(ban)(ban)(ban)由上(shang)輥(gun)的(de)自(zi)重(zhong)壓力(li)單板(ban)(ban)(ban)(ban)(ban)向(xiang)前移動(dong)，單板(ban)(ban)(ban)(ban)(ban)通(tong)過兩(liang)輥(gun)和上(shang)下(xia)空(kong)氣噴(pen)嘴，同時(shi)達到干(gan)(gan)燥(zao)(zao)(zao)(zao)(zao)和熨燙的(de)效果。因此，這臺(tai)機器的(de)單板(ban)(ban)(ban)(ban)(ban)是光(guang)滑(hua)的(de)，沒有(you)痕跡(ji)。
