    • This heating blow-molding machine fabricates a number of bottle-shaped containers from biaxially oriented plastic pieces or parisons by supplying the plastic pieces to a heating unit to heat them to the orientation temperature and then supplying them to 12-station rotary blow molding machine for biaxial orientation. Each of the plastic pieces or parisons is made of polyethylene terephthalate resin to provide a thin-walled transparent bottle-shaped container of cylindrical shape with one bottom and a prefinished neck portion injection molded simultaneously in numerous number by an injection molding machine. This blow-molding machine consists of a turntable for the heating unit, a turntable for a blow-molding machine, and a turntable for loading and unloading the pieces and the products blow-molded from the pieces. Each of the turntables is continuously turned in predetermined direction at an intrinsic speed set with respect to the number of stations provided thereat, the time required for heating the pieces, and another time required for blow-molding and cooling the pieces, etc. Further, a rotor is employed to transfer the pieces or container products between the turntables rotated at their intrinsic speeds, respectively. The rotor is rotated according to a speed curve at a moving speed equal to the peripheral speed of the turntable opposite to the turntable for transferring the pieces held thereby at the holding portions.
    • 该加热吹塑机通过将塑料片供给加热单元将其加热至取向温度,然后将其供应到12台旋转吹塑机,从双轴取向的塑料片或型坯制造多个瓶形容器 双轴取向。 每个塑料件或型坯由聚对苯二甲酸乙二醇酯树脂制成,以便通过注射成型机同时许多数量地提供具有一个底部的圆筒形薄壁透明瓶形容器和预先制备的颈部。 该吹塑机由用于加热单元的转盘,用于吹塑机的转台和用于装载和卸载件的转盘和从件中吹塑成型的产品组成。 每个转盘以相对于其设置的台数设定的固有速度连续转动预定方向,加热片所需的时间以及吹塑和冷却片等所需的时间。此外, 使用转子分别在以其固有速度旋转的转盘之间转移件或容器产品。 转子以与转台相对的转盘的圆周速度相等的移动速度根据速度曲线旋转,以将由此保持在其上的保持部分传送。
