Film blowing machine when the membrane vesicles filed in normal operation after, should immediately check on the membrane thickness, width, plasticizing quality, vertical and horizontal contraction rate, various machine parts tie to be adjusted, mainframe extrusion speed and traction speed and fan speed should be adjusted to specified requirements, to keep it consistent. The plastic melt the filter head to impurities from the mouth of the die, the wind ring cooling, blown the lambdoidal board, traction roll, roll the finished film is coiled into a cylinder. In production must be careful operation, it is strictly forbidden to film bubble wrap around the traction roller and traction rollers. When the film is cut, not tools on the guide roller surface cutting, to scratch the surface of the roller, affecting the appearance of film. For example, the real power of the motor is 50Hz, and you in production really only need to 30Hz enough production, the superfluous energy is wasted, the frequency converter is to change the output power of the motor to achieve energy-saving effect. Heating part of the energy saving: the heating part of the energy saving is mostly used electromagnetic heater, energy saving rate is about 30%-70%.
