ABSTRACT
In recent years, China's textile industry has made great development, has become
the world's first textile big country. Mercerizer dyeing equipment is extensive use of
the domestic textile industry, implementation driven by a controllable AC speed
control system, because there are many DC drive system drawbacks: such as the need
to maintain long-term reliability is relatively low, relatively poor flexibility , the
response is slow, long time and no trouble parking fault self-test function, so seriously
affected the normal operation of the production line.
In this design proposes PLC AC variable speed control system based on the
system from the master machine and the various motives are AC motors, high
functionality using a common inverter v / f control, thereby constructed a new silk
Zhiran system. The machine is designed silk knitted fabric mercerized, weave cloth
weaving workshop relatively hard and feel good, while many spots, need to go
through a series of processing, such as caustic, go to spots. Because the base cloth
soaked through alkaline big, you need to use an acid neutralization, mercerizing
machine is completion of the joint process.
This paper describes the status of the development of domestic printing and
dyeing industry , then introduces the development and current status of the motor
speed control technology, the mercerizer AC variable speed system solutions were
demonstrated , and then introduce the model and the performance of the hardware
required for the design , and finally , introduced the system of the production process ,
the electrical structure of the system hardware configuration and software.
Key words: mercerizer; programmable controller; niversal Converter;
