A Comprehensive Guide to Ring Frame Machine

 

What is ring frame machine?

Ring frame machine: a spinning machine in which half products of roving or sliver are drawn, twisted and wound into muslin in the spinning process; sliver is drawn and twisted on a roving machine to make roving; a combing machine to carding fibers into combing slivers; a needle carding machine to combine slivers; needle drawing improves sliver structure; roving is further twisted into muslin on a ring spinning machine; spinning machine is the main machine for spinning. The output and quality of fine yarn are the comprehensive reflection of each process of spinning technology.

What is the importance of ring frame machine?

The spinning process is the last process of spinning, but also an important process of the textile factory, the total number of spinning process is an important symbol to measure the size of the cotton textile factory and production capacity, the output of spinning process determines the textile factory each process of mechanical equipment equipment, the output level, determines the production level of the enterprise; The quality and consumption of fine yarn determine the cost of spinning. The breaking rate of fine yarn is an important index of enterprise assessment. Therefore, the spinning process can comprehensively reflect the production technology and management level of a cotton mill.
The task of spinning process
1. Draft
The fed roving is drawn evenly long and fine to the required number of special yarn.
2. Twist
Add appropriate twist to the drawn whisk to make the yarn have certain physical and mechanical properties such as strength, elasticity, luster and feel.
3. Winding
The spun yarn is wound on the bobbin in a certain shape to facilitate transportation, storage and further processing.

What is the ring frame process?

Ring spinning frame is the most common. The common ring spinning frame is of double-sided multi-spindle structure, which is mainly composed of feeding mechanism, drafting mechanism, twisting winding mechanism and forming mechanism. The roving is unwound from the roving tube on the roving frame and fed into the drawing device for drawing through the guide rod and the slow reciprocating cross movement of the guide horn. The drawn whisker is output from the front roller through the yarn guide hook, through the wire ring, and wound to the bobbin tight on the spindle. The spindle turns at high speed. The wire ring is driven to turn at high speed on the steel collar by the yarn strip with certain tension. Each turn of the wire ring adds a twist to the drawn whisk. Because the rotation speed of the wire ring is less than that of the yarn tube, the continuous output yarn strip of the front roller is wound to the yarn tube. The speed difference between the wire ring and the yarn tube is the number of winding turns per unit time of the yarn tube. Depending on the control of forming mechanism, the steel collar plate rises and falls according to a certain rule, so that the fine yarn is wound into a certain shape yarn.

What is the disadvantage of ring frame?

The production of spinning frame accessories is the first step in the textile industry chain. The quality of its products, the efficiency of production and the size of processing cost play an important role in the whole industry chain. Therefore, the development of spinning technology and the promotion of new technology are paid more attention at home and abroad. With the continuous development of spinning technology, there are two kinds of spinning technology in spinning production at present: one is ring spinning technology, the other is new spinning technology, which is widely used.
Due to long hours of work, there will be some problems in the spindle position of the spinning frame, which need to be repaired by maintenance personnel, which is a very important quality control work in the spinning mill. Due to the large number of spindles, from thousands to hundreds of thousands in the same plant, how to eliminate these defective spindles is a long and arduous task, but it is extremely necessary to reduce yarn quality uneven. Most of these defects are related to ring and spoke damage, draft difference, roller deviation, yarn frame, etc.
