Overview The steamer is used in the finishing workshop of the woolen textile mill in the textile industry. It is used for the flat steaming of rough combed wool fabrics or wet textiles. The fabric can be processed by the machine to obtain a supple feel, increase natural luster and further enhance the stereotype effect of the fabric. . Steaming machine main controller is completed by the programmable controller (PLC), complete the speed and tension settings, inverter parameter settings, access to the cloth logic control operations. The frequency converter automatically operates according to the set parameters and the given speed and tension, so that the fabric can obtain high-quality steaming effect. Second, the working principle Upper cloth: The upper cloth is the base cloth wrapped around the big roll when the base cloth is replaced, and it is replaced once in the first half of the year. When the cloth is clothed, only the large roller drive is needed. At this time, the X1 and X3 terminals of the large roller drive are closed, and the X2 terminal is disconnected. The speed of the upper cloth is adjusted by the speed potentiometer. Into the cloth: Into the cloth is to squeeze the steam cloth in the bottom cloth wrapped around the big roll, then the small roller frequency converter X1 and X3 terminal is closed, X2 terminal is disconnected, run in line speed mode, the cloth speed from speed The potentiometer is set and passed to the big roller inverter through the actual line speed of AO1 output; the X1 terminal of the big roller frequency converter is closed, the X2 and X3 terminals are disconnected, and it runs in the tension winding mode. The size of the tension on the cloth comes from PLC tension given control. Out of the fabric: When the cloth is released, the rollers rotate in the opposite direction to remove the steamed cloth and wrap the back cloth around the small roller. At this time, the X1 and X3 terminals of the small roller drive are disconnected, and the X2 terminal is closed to close the tension. Roll mode operation, the size of the tension on the cloth is controlled by the tension from the PLC, the small roller inverter is transmitted to the big roller inverter through the actual line speed of AO1 output; the X2 and X3 terminals of the big roller inverter are closed, and the X1 terminal is disconnected , Operate in line speed mode, the cloth speed is set by the speed given potentiometer. The X1 terminal of the output drive is closed in speed mode and the speed is set by the speed reference potentiometer. note: 1. If abnormal alarms such as alarms or faults occur during the operation, you must remove the abnormalities and close the "Reset" terminal of the corresponding inverter to clear the alarm before continuing. 2. The output of the alarm dry node in the figure is the normally open contact of the relay. If you want to use the normally closed contact, change the TA to TB. 3. Before starting the cloth and other operations, you must first check and adjust the rotation direction of the motor, and then the wiring direction of the encoder. Refer to the notes in function codes P2.37 and P2.45 for the adjustment principle. In this case, it is assumed that the rotation direction of the large and small rolls when the frequency converter is rotating is the direction needed to feed the cloth. It is recommended to set this assumption. 4. For other function codes that need to be set, see the following parameter setting table. The adjustment principle of the parameters that need to be adjusted according to the site conditions is referred to in the notes. Special emphasis should be placed on: Before starting the operation of cloth feeding, cloth exit, etc., it must be set correctly. Roll diameter and thickness of the material, so as not to error is too large than the inverter adjustment range, resulting in abnormal operation. 5, the inverter factory default use the same power level of 4-pole motor, if the actual use of the motor and the default is not consistent, you must set the motor parameters according to the motor nameplate (PA.01 ~ PA.04), it is best to be completely empty in the motor The motor parameter tuning is performed once. Third, the system configuration 6300V frequency converter is based on the 6000V series of general-purpose frequency converter, specially designed for the wire drawing, printing and dyeing, textile and other industries need tension control winding needs to improve the design of the special frequency converter, precise torque control and rich and flexible configuration program So that it can meet the winding needs of various industries such as printing, winding and steaming. Although this case is a practical application of a 6300V inverter on a steaming machine, it can be applied to applications such as double frequency conversion and dyeing. Fourth, system advantages 6300V frequency converter is specially designed for the wire drawing, printing and dyeing, textile and other industries need to improve the tension control of the winding needs of the special inverter, without the need to install linear speed sensors and tension sensors, cost savings for the customer, precise torque control and rich, flexible The configuration scheme enables it to meet the winding needs of various industries such as printing, winding, and steaming.
