     木(mu)(mu)材剝(bo)皮(pi)(pi)(pi)機，所屬技術領域為造紙機械。將現有木(mu)(mu)材剝(bo)皮(pi)(pi)(pi)機筒(tong)壁(bi)上(shang)的每(mei)個排皮(pi)(pi)(pi)孔(kong)均(jun)擴(kuo)大(da)，且排皮(pi)(pi)(pi)孔(kong)周邊向外傾斜一角度(du)α。裝上(shang)“山(shan)”字(zi)形剝(bo)皮(pi)(pi)(pi)刀后,在"山(shan)"字(zi)形剝(bo)皮(pi)(pi)(pi)刀的周邊均(jun)有排皮(pi)(pi)(pi)間隙。“山(shan)”字(zi)形剝(bo)皮(pi)(pi)(pi)刀上(shang)有多個排皮(pi)(pi)(pi)間隙,每(mei)個排皮(pi)(pi)(pi)間隙均(jun)呈(cheng)內小外大(da)狀(zhuang),滾(gun)筒(tong)轉速(su)為無(wu)級變(bian)速(su)。這(zhe)樣(yang),剝(bo)皮(pi)(pi)(pi)時不(bu)需用(yong)水,實(shi)現不(bu)同(tong)樹(shu)種、不(bu)同(tong)徑級、不(bu)同(tong)含水率木(mu)(mu)材的順利剝(bo)皮(pi)(pi)(pi)和(he)(he)排皮(pi)(pi)(pi),樹(shu)皮(pi)(pi)(pi)不(bu)會堵塞排皮(pi)(pi)(pi)孔(kong),取(qu)得最佳剝(bo)皮(pi)(pi)(pi)效果和(he)(he)最佳生產率,木(mu)(mu)質(zhi)損失小。
