With the development of society, people have a huge demand for some portable daily necessities, and the process and quality requirements of plastic products are changing with each passing day. The front-end source manufacturing industry of plastic products requires a sheet extruder. The following is easy to drive. The application of GT200 series products on sheet extruder is explained.
2. Application of Yidrive GT200 series frequency converter in sheet extruder
The sheet extruder mainly includes: screw extruder, sheet extruder die, three-roll calender, trimmer, torque winder and other equipment. When the sheet extruder is working, the materials are added from the hopper of the extruder. After the materials are heated to a certain temperature by the electromagnetic heater, they are then radially extruded by the screw extruder into the sheet forming die, and then the die The first is extruded in the form of a sheet, and then after passing through a three-roll calender, the waste edges on both sides are removed by an in-line trimmer, to the tension frame, and then to the following torque winder for rolling operation.
During the operation of the equipment, it is required to control the screw extrusion temperature and the pressure of the sheet extrusion die head to be constant. The die head pressure is variable during online operation. When the die head pressure becomes larger, the host computer controller sets the frequency When the die pressure becomes smaller, the given quantity of the inverter from the host computer controller becomes larger, so that the motor decelerates, thereby reducing the die pressure. In the extrusion process, the die pressure will have slight variables, so it is necessary to monitor the die pressure of the sheet extrusion in real time, and adjust the speed of the screw extruder in real time, and the performance requirements of the frequency converter The acceleration and deceleration response is fast, the speed stabilization accuracy is high, and the AI port resolution is high. During the normal operation of the GT200 product, the output frequency can quickly change according to the host computer command, and the speed stabilization accuracy is high. The resolution of the AI port is: highest frequency× ±0.1%, frequency accuracy: the highest frequency × ±0.2%, steady-state accuracy of operating speed: ±0.5% of the rated synchronous speed, which can meet on-site application.
Use terminal to start on site, the upper computer controller gives 0-10VDC control frequency converter, fault alarm output, frequency converter analog feedback to the upper computer for closed loop. Before trial operation, confirm whether the motor rotation direction is consistent with the mark.
The GT200 series products of Yidrive Electric can have good speed control accuracy and speed stabilization accuracy on the sheet extruder equipment, thereby improving product quality and work efficiency. GT200 series products are beautiful and elegant, and extremely high reliability is suitable for this type of Customer use, won praise from customers is worthy of promotion and application.
