Summary

In recent years, with the fierce market competition and the continuous improvement of the technical level of textile machinery electromechanical integration, domestic and foreign textile machinery have generally entered the era of variable frequency speed regulation. Frequency conversion speed control replaces the traditional mechanical structure. The main technological processes and basic loom equipment such as blowout, carding, slivering, roving, spinning, winding, warping, sizing, shuttleless looms, etc. have been widely adopted. This article introduces     the application solution of Jarol shares JAC580F series super-start frequency converter on the shuttleless loom.

1. Introduction

There are many classifications of looms. According to the weaving method, they can be divided into shuttle looms and shuttleless looms. Compared with shuttle looms, shuttleless looms have the advantages of low vibration, low noise, fast speed, and high efficiency. The main working principle is realized by the five movements of shedding, weft insertion, beating-up, crimping, and warp let-off. First, the brown frame of the loom moves up and down according to the organization law to form an opening to make the yarn layer up and down, and then different weft insertions In this way, the weft yarn is driven into the weaving mouth to complete one interweaving, the crimping mechanism draws away from the fabric, and the warp sending mechanism sends out the warp yarn to form a continuous movement to complete the weaving. According to the different weft insertion methods, it can be divided into rapier, air jet, water jet, projectile, multi shuttle and other models.

2. The Requirements of the Shuttleless Loom for the Inverter

(1) Reduce power consumption and cost, with significant power saving effect.

(2) The asynchronous motor can realize stepless speed regulation.

(3) Simplify the mechanical structure, improve production speed and production efficiency.

(4) Start smoothly, eliminate mechanical impact, and improve the reliability of textile machinery equipment.

3. Introduction of Jarol Shares JAC580F Series Ultra-start Inverter

JAC580F series super-start inverter is a special product designed for the starting characteristics and application environment of shuttleless looms. According to different installation requirements, it is divided into two series: built-in and external. It has fast startup response, anti-blocking in cotton, high temperature resistance, It has the advantages of moisture resistance and corrosion resistance, and can be widely used in the matching and transformation of the main shaft drive of water jet looms, air jet looms and rapier looms.

4. Application Advantages

(1) Increase the speed without affecting the product quality, and the production efficiency is higher.

(2) Stepless speed regulation, reducing the downtime rate when changing products, and avoiding the replacement of pulleys.

(3) The frequency conversion starting grid has less impact and the input contactor has a longer life.

(4) Frequency conversion jog, replacing the original loom system power supply electric, with higher reliability.

5. Concluding Remarks

The application of AC variable frequency speed regulation technology in textile equipment is becoming more and more extensive, which has greatly promoted the technological progress of textile equipment. The application of JAC580F super-start frequency converter of Jarol shares on shuttleless looms has greatly improved The reliability of textile machinery equipment is improved, and the quality of textiles and the degree of automation are improved.
