    • PURPOSE:To enable to extrude large volume of resin and obtain a film of high quality, by a method wherein a large number of functions is divided into a melter and a homogenizer and a rotor is arranged in the intermediate part of them. CONSTITUTION:Discharge pressure of a melter 11 is detected by a pressure detector 16 feedback of which is applied to a pressure adjusting device 17, through which the discharge pressure is controlled by adjusting a speed of an electric motor A13 through control part A12 of the electric motor. A rotor 18 which is downstream a filter A15 is driven by an electric motor B20 whose speed is adjusted by a control part B19, and molten resin to be supplied from the filter A15 is quantified at every cog of a gear. The stable quantitative molten resin is supplied to a homogenizer 22 on an outlet side of the rotor 18 from the rotor 18, through which a temperature of the resin is lowered to a target temperature and at the same time the titled device possesses a screw equalizing the temperature of the resin. The screw is driven by an electric motor and generates pressure necessary for the resin to pass through a filter B23 and a die 24 located downstream of the screw.
    • 目的:为了能够挤出大量树脂并获得高质量的膜,通过将大量功能分成胶机和均化器并且在其中间部分布置有转子的方法。 构成:熔化器11的排出压力由压力检测器16检测,其反馈被施加到压力调节装置17,通过调节电动机A13的速度来控制排出压力,通过电动机A13的控制部分A12 发动机。 在过滤器A15下游的转子18由通过控制部分B19调节速度的电动机B20驱动,并且以每齿轮齿轮量化从过滤器A15供给的熔融树脂。 稳定的定量熔融树脂从转子18在转子18的出口侧的均化器22中供给,树脂的温度降低到目标温度,同时标称装置具有将 树脂的温度。 螺杆由电动机驱动,并产生使树脂通过位于螺杆下游的过滤器B23和模具24所需的压力。
