Abstract

The invention discloses a programmable logic controller with the wobble frequency function, which comprises a wobble-frequency primary reducing module, a wobble-frequency secondary reducing module, a wobble-frequency primary increasing module, a wobble-frequency secondary increasing module and a control module. The wobble-frequency primary reducing module is used for reducing the wobble-frequency maximum amplitude frequency of a frequency converter to the wobble-frequency maximum hopping frequency. The wobble-frequency secondary reducing module is used for reducing the wobble-frequency maximum hopping frequency to the wobble-frequency minimum amplitude frequency. The wobble-frequency primary increasing module is used for increasing the wobble-frequency minimum amplitude frequency to the wobble-frequency minimum hopping frequency. The wobble-frequency secondary increasing module is used for increasing the wobble-frequency minimum hopping frequency to the wobble-frequency maximum amplitude frequency. The control module is used for executing the wobble-frequency primary reducing module, the wobble-frequency secondary reducing module, the wobble-frequency primary increasing module and the wobble-frequency secondary increasing module in looping mode. The programmable logic controller can be collocated with general frequency converters to achieve the wobble frequency function required by textile industry, and special frequency converters are not needed.

Description

technical field [0001] The present invention relates to a wobble method, and in particular to a wobble method implemented by a programmable logic controller. Background technique [0002] In people's daily life, textile products can be said to be indispensable for people's livelihood, and the precision integration of textile machinery significantly affects the quality of textiles. In recent years, with the improvement of people's living standards, more and more people have higher and higher requirements for the quality of clothing and daily necessities. Therefore, the high-precision integrated textile machinery has been on the rise in recent years. Therefore, it is particularly important to precisely control the spindle forming process in the textile process. [0003] In the winding process of textile machinery, spindle forming can be divided into two independent motions superimposed, one is a constant speed (constant speed) rotary motion to rotate the paper system, and the...
