    • The present invention provides an advanced method for producing a colour steel plate with multicoloured patterns, on the one hand, the PLC control module of the servo control system collects the process speed and the rotation speed of each roller of the roller coating unit, calculates out the theoretical roller surface linear velocity and makes the theoretical roller surface linear velocity be consistent with the process rotation speed; on the other hand, the actual roller surface linear velocity of each roller of the roller coating unit is collected by a servo control module having an encoder, and the signal of the actual roller surface linear velocity is input into the PLC control system, so that the PLC control system can compare the actual roller surface linear velocity with the theoretical roller surface linear velocity, and adjust current frequency until the actual roller surface linear velocity is consistent with the theoretical roller surface linear velocity. The above mentioned control method ensures the actual roller surface linear velocity is consistent with the process rotation speed, so there is no need to stop the line for adjusting in the production process, thus increasing the production efficiency.
    • 本发明提供了在用于制造彩色钢板与多色图案,在一方面先进的方法,该伺服控制系统的PLC控制模块收集的处理速度和辊涂单元的每个辊的旋转速度,计算出 理论辊表面线速度,并且使理论辊表面线速度为与所述过程转速相符; 在另一方面,辊涂单元的各辊的实际辊表面线速度通过具有在编码器的伺服控制模块和实际辊表面线速度的信号被输入到PLC控制系统收集的,所以没有 PLC控制系统可以比较与理论辊表面线速度的实际辊表面线速度,并调整电流频率,直到实际辊表面线速度与理论辊表面线速度相一致。 上述控制方法可以确保实际辊表面线速度为与所述过程转速一致,所以没有必要停止生产线,用于调节在生产过程中,因此增加了生产效率。
