Abstract Textile sizing process is an important process, a direct impact on the performance of sizing the back of the weaving process. Traditional sizing sizing machine industry in China still has a fairly large proportion, with the improvement of products, the traditional sizing machine production can no longer meet the needs of sizing machine to control part of the transformation is a very large subject. The main purpose of this article on the sizing machine through an electrical control system transformation, in order to build a PLC and inverter as the core of a complete electrical control system sizing machine in order to achieve automatic control yarn constant tension and improve the quality of the sizing The purpose of the subsequent production to meet demand. For the use of PLC control in the other inverter control system of constant tension, the yarn of the system constant tension control is mainly reflected in the automatic adjustment of the inverter, inverter line in accordance with the speed of change in yarn diameter calculated volume changes, automatically change the output frequency to the effect of constant tension control. In addition, the system of slurry temperature, slurry liquid, to achieve automatic control sizing regain. Key words: sizing machine; control; constant tension; inverter.
