Plastic extruder principle is a solid plastic at a pressurized condition at a screw rotation extruder heating and melting, plasticizing, through a die into a particular shape and the same cross-sectional shape of the die and a continuous plastics. Most previous extruder drive DC drive or electromagnetic speed control inverter wholesale, former maintenance complex and the cost is huge, affecting the efficient use of equipment, which is low speed precision, low-grade products converter agent, which are in a very large extent, affected the development of the extruder. Because AC inverter technology in China in recent years has been rapid development, but also in the frequency range of frequency control, dynamic response, speed accuracy, low torque, slip compensation, communication, intelligent control, power factor, efficiency, and is easy to use and other aspects of the way the past is unmatched speed, so by the extruder manufacturing enterprises of all ages, in the new extrusion machinery, especially plastic machinery have adopted a high-performance drive, while the original old extruder machine will enter a new round of transformation period. Extruder winding motor PID control principle: In addition to the speed of synchronization, the film winding motor winding is also a focus on plastic film extruder, now using the PID switching Omron 3G3MZ to achieve, in just getting the time machine, Because part of the winding tension has not been established, then the use of speed synchronous converter, through multi-function terminal (s3 ~ s6) to make the PID control failure converter sales where the good, then the speed of the drive for instructions guide roller motor The output signal of the synchronous speed. This is because when you have just completed a film reel change volume, due to relatively large changes in tension, if the PI closed-loop control is likely to cause a large overshoot, resulting in a film format shake frequently, at this time if the open-loop control is more an advantage . Once part of the winding tension began to build, switching to high-security PID control inverter | converter agent | Yueyang Ohm Electric (certified merchants) by Ohm Electric Co., Yueyang City.
