    • PURPOSE: An air-ring for manufacturing vinyl tube is provided to dispense uniformly air pressure from an outlet with perforated window formed by equally divided angle from the center. CONSTITUTION: An air-ring for manufacturing vinyl tube comprises an outlet, a first partition(20), a second partition(30), a third partition(40), and perforated windows(21,31). The outlet is formed in the inside of a body(10) of a ring type installed around an outlet of an extrusion molding machine. The first partition, the second partition, and the third partition are injection-molded in an inner air remaining chamber(12) of the body. The first, second, third partitions are crossed in the upper and lower part. The first and the second partition block the upper and lower part of the body. The perforated window is formed to the direction which the first and the second partition are crossed.
    • 目的:提供用于制造乙烯基管的空气环,以从具有与中心成等角度形成的穿孔窗口的出口均匀分配空气压力。 构成:用于制造乙烯基管的空气环包括出口,第一隔板(20),第二隔板(30),第三隔板(40)和穿孔窗口(21,31)。 出口形成在安装在挤出成型机的出口周围的环形体(10)的内部。 第一分隔件,第二分隔件和第三分隔件被注塑在主体的内部空气剩余室(12)中。 第一,第二,第三分区在上部和下部交叉。 第一和第二分区阻挡身体的上部和下部。 穿孔窗形成为第一和第二隔板交叉的方向。
