所述的螺杆包括螺槽和螺棱,螺杆的主轴直径从输入端开始由细变粗,所述螺杆后部,其螺棱有至少一处从螺旋状变为横条状螺棱,同时所述机筒相应位置上开有抽真空口,连接抽真空机;
所述的冷却装置为环形排孔冷气机出风口。
优选地,所述螺杆长径比为20-60。
优选地,所述加热器为铸铝加热器、云母加热器或者陶瓷加热器其中的一种。
优选地,所述机架上设有螺杆冷却系统。
优选地,所述管状挤出头对面设有牵引装置、切割装置和水管成品收卷装置。
本实用新型由于采用上述结构后,运用专用加工设备,可极大的增加产品的透明度,既可提高抗静电和润滑性能,又可提高防湿性能,能明显降低摩擦系数和粘结阻力,显著提高吹膜(挤塑)时的效益,可有效地防止薄膜间的粘结和粒料间的结块,并可增加薄膜表面的光洁度,防止灰尘在制品表面的附积,生产出非常光滑的塑料成品。

具体实施方式
下面结合附图和具体实施方式对本实用新型进行详细说明。
一种专用于生产透明饮用水管的单螺杆挤出机,如图1、2、3和4所示,包括机架1,机架1上安装有机筒2,机筒2内安装有螺杆3和加热器,机筒2一端安装有减速机4,减速机4连接电机,机筒2另一端设有管状挤出头5,管状挤出头5外部设有冷却装置6,管状挤出头5对面设有气刀7;所述的螺杆3包括螺槽8和螺棱9,螺杆3的主轴直径从输入端开始由细变粗,所述螺杆3后部,其螺棱9有至少一处从螺旋状变为横条状螺棱10,同时所述机筒2相应位置上开有抽真空口11,连接抽真空机;
所述的冷却装置6为环形排孔冷气机出风口。
所述螺杆3长径比为20-60。
所述加热器为铸铝加热器、云母加热器或者陶瓷加热器其中的一种。
所述机架1上设有螺杆冷却系统。
所述管状挤出头5对面设有牵引装置、切割装置和水管成品收卷装置。
工作原理如下:
(1)对乙烯-醋酸乙烯共聚物颗粒进行前期处理;
(2)将乙烯-醋酸乙烯共聚物、增透剂和开口剂进行混合处理;
(3)将混合物投入挤出系统的料斗中;
(4)混合物在挤出系统中被初级粉碎和压实;
(5)混合物从料斗进入挤出系统,由于机筒与螺杆之间的相对运动,从而在物料与机筒之间以及物料与螺杆表面之间产生了摩擦力,混合物开始融化;
(6)初期融化的混合物进入分段式熔融段,混合物在摩擦热和机筒外部加热的作用下,温度不断升高而呈现黏流状,并在机筒内表面形成熔膜,旋转的螺棱不断将熔膜刮落而在螺槽中形成一个熔池,混合物变为液态;
(7)液态的混合物进入抽真空区,横条状的螺棱以离心力将空气推向液流外围,然后抽真空机将空气抽走;
(8)混合物被螺杆继续推进,进入第二熔融段;
(9)混合物被螺杆继续推进,进入第二抽真空区;
(10)混合物进入挤出系统头,经过环形头,输出为管状的混合物被冷却装置出风口冷却,并将蒸汽吹掉,提高混合物的透明度,同时被气刀从中间吹气成型;
(11)半成品后处理。
运用专用加工设备,可极大的增加产品的透明度,既可提高抗静电和润滑性能,又可提高防湿性能,能明显降低摩擦系数和粘结阻力,显著提高吹膜(挤塑)时的效益,可有效地防止薄膜间的粘结和粒料间的结块,并可增加薄膜表面的光洁度,防止灰尘在制品表面的附积,生产出非常光滑的塑料成品。
上述实施方式只是本实用新型的优选实施例,并不是用来限制本实用新型的实施与权利范围的,凡依据本实用新型申请专利保护范围所述的内容做出的等效变化和修饰,均应包括于本实用新型申请专利范围内。
