【摘要】:冷轧堆染色工艺是一种介于浸染工艺与连续轧染工艺之间的半连续化工艺。现阶段,冷轧堆染色主要应用于机织物的染色工艺上,针织物的结构和性能相比于机织物有较大的差别,冷轧堆染色工艺应用于针织物的染料和电气控制设备的选择也有一定的差异。提高针织物冷轧堆染色工艺品质是多因素的系统工程,而张力控制是其中非常重要的环节,针织物印染时会因张力偏差而产生缝头印,而且收卷时也会发生过松或过紧而严重影响染色效果。由此可见,加大对针织物冷轧堆染色机张力控制的研究将会进一步缩减印染成本。本文从针织物冷轧堆染色机的组成和生产工艺入手,分析针织物的性能和冷轧堆染色的特点,将针织物冷轧堆染色机分为进布冷却单元、印染单元和收卷单元进行研究进而确定各单元张力控制设计方案。根据针织物冷轧堆染色中各工艺单元对张力的不同控制要求,采用独立调节与主动和被动张力控制相结合,对不同工序段张力采用不同的控制模式,完成预设的控制目标。为解决针织物冷轧堆染色机张力控制的难点,通过各单元进行动态力学分析,建立张力控制模型,搭配更适应动态非线性系统的模糊自适应PID算法实现张力控制。考虑到轧车速度为基准和前两个单元的相似的恒控制特点,对针织物冷轧堆染色机的进布冷却单元和印染单元分别采用角位移传感器和张力传感器与高性能交流矢量变频器搭配进行控制,保证印染的稳定。根据针织物收卷的剩余缠绕张力和初始缠绕张力之间的关系,对收卷单元采用高性能交流矢量变频器和张力传感器进行张力锥度控制,保证收卷的剩余缠绕张力稳定。利用Simulink对各单元张力控制系统进行仿真实验,得到了响应的张力和速度的响应曲线,分析了控制算法和控制模型的合理性,还使用Matlab/GUI实现了针织物冷轧堆染色机多单元张力控制系统的仿真曲线和参数实时在GUI界面上的显示,在此基础上对多单元张力控制系统进行了多组仿真实验。通过仿真实验为进一步研究针织物冷轧堆染色机张力控制系统提供了理论参考。
[Abstract]:Cold pad batch dyeing process between dyeing process and continuous pad dyeing process for semi continuous. At this stage, the dyeing process of cold pad batch dyeing is mainly used in woven fabric on the structure and properties of knitted fabrics than woven fabrics have great differences, technology should be used for cold pad batch dyeing of knitted fabrics and dyes electric control equipment choice also has certain differences. To improve the quality of cold pad batch dyeing of knitted fabric is a system engineering of many factors, and the tension control is a very important part of the knitted fabric dyeing when the tension deviation caused joint seal and rolling will occur too loose or too tight and serious the dyeing effect. Thus, increase the dyeing machine tension control research will be further reduced the cost of printing and dyeing of knitted fabric. The cold rolled heap from fabric cold pad batch dyeing composition and production process of the machine, analysis The properties of knitting fabric and cold pad batch dyeing, knitted fabrics pad into the cooling unit of cloth dyeing machine, dyeing unit and winding unit of each unit and to determine the design of tension control scheme. According to the fabric pad dyeing on the tension of each process unit with the control requirements, the independent regulation and active and passive tension control combined with different control modes of different tension process, complete control of the target. In order to solve the difficulties of knitted fabric cold pad batch dyeing machine tension control, dynamic mechanical analysis by each unit, a tension control model, collocation is more suitable for fuzzy adaptive PID algorithm of dynamic nonlinear system to realize tension control. Considering the rolling speed constant control car benchmark and the first two units similar to that of knitted fabric cold pad batch dyeing machine into the cooling unit and single printing and dyeing cloth Yuan respectively by the angular displacement sensor and a tension sensor with high performance AC vector inverter control to ensure the collocation, printing and dyeing stability. According to the fabric winding residual winding tension and winding tension relationship between initial tension, taper control of the coiling unit adopts high performance AC vector frequency converter and tension sensor, ensure that the residual wound stable tension winding. Simulation experiments on each unit of tension control system based on Simulink, the response of the tension and speed, analyzes the rationality of the control algorithm and control model, but also realize the use of Matlab/GUI knitted fabric cold pad batch dyeing machine multi unit tension control system simulation curves and parameters in real-time GUI interface on the show, on the basis of the multiple sets of simulation experiments of multi unit tension control system. Through the simulation experiment for the further study of needle A theoretical reference is provided for the tension control system of the fabric cold-rolled pile dyeing machine.
