Summary
 
In recent years, with the continuous development and maturity of domestic frequency conversion technology, the application of frequency converter as a mature high-tech on the spinning frame has become more and more common. The frequency converter can realize automatic stepless speed change, optimize spinning conditions, and further reduce Decapitation, reduce hairiness, achieve high quality and high yield, and reduce energy consumption. This article focuses on the application of the easy drive GT210 frequency converter on the spinning frame.

1. Overview
 
Spinning is the last process of weaving. It is spinning roving into a spun yarn with a certain linear density and meeting quality standards or customer requirements for twisting, weaving or knitting. The main task of the spinning process is: in the production process of spinning, the fed roving is evenly stretched and thinned to the required linear density of the spinning; the drafted sliver is added with a proper twist to make the yarn It has certain physical and mechanical properties such as tension, elasticity, luster and hand feeling; the spun yarn is wound on the bobbin according to certain molding requirements for transportation, storage and subsequent processing.
 
2. The application advantages of the frequency converter on the spinning frame
 
For the traditional spinning frame, the direct start of the motor has a large impact, and the speed adjustment is achieved by replacing gears with different numbers of teeth, and it is impossible to achieve stepless speed adjustment, low production efficiency, high end breakage, and relatively single processed products , Lack of competitiveness; the use of frequency converter to drive the new spinning frame not only can stepless speed regulation, but also has the following advantages:
 
(1) Frequency conversion speed regulation can reduce the end breakage on the basis of increasing the output, or significantly reduce the end breakage of small and large yarns while maintaining the current output.
 
(2) The spindle speed adjustment range is wider, and it is quick and convenient to change the varieties without changing the belt pulley.
 
(3) For some varieties with certain difficulty in spinning, such as strong twisted yarn, core-spun yarn, hemp/cotton yarn and high-end combed products, the best point of the production process can be selected through variable speed, which can maximize the yield and reduce the end breakage.
 
(4) The use of a frequency converter to control the main motor can maximize the potential to tap the reactive power of the motor, make full use of and improve the power factor, thereby achieving the purpose of saving electricity.
 
(5) The reduction of spun yarn breakage can expand the stands, reduce labor, and save production costs.
 
(6) Speed ​​reduction by frequency conversion has a better effect on reducing the hairiness of small yarns, which is beneficial to reduce the extreme difference in hairiness of large, medium and small yarns, and has potential commercial value.
 
(7) The inverter can be connected to the PLC and computer local area network on the equipment to monitor online production and quality.
 
3. Features of Easy Drive GT210 Inverter
 
(1) The starting torque is large, which fully meets the working requirements of the spinning frame;
 
(2) High accuracy of speed stabilization, stable operation, reducing yarn breakage rate;
 
(3) Install a protective cover to improve the protection level and meet the high temperature and humidity environment of the fine sand workshop;
 
(4) Independent air duct, and an additional protective net design, dustproof and prevent yarn blockage, strong environmental adaptability;
 
(5) Various comprehensive protections such as overcurrent, overvoltage, short circuit, phase loss, undervoltage, etc., reduce the probability of motor damage;
 
(6) Powerful functions such as swing frequency function and simple PLC to meet the technological needs of spinning frame;
 
4.Summary
 
Through the transformation and verification of several spinning frames in a textile factory in Jiangyin, it is shown that the easy-drive GT210 inverter can not only effectively meet the needs of customers in all aspects, but also improve the degree of equipment automation, protect the equipment, and reduce equipment maintenance. , Improve product quality and processing efficiency. After long-term use and verification by customers, it has been recognized by customers.
