What is a ring frame machine?

Ring frame machine: a spinning machine in which semi-finished products are drawn from roving or sliver, i. h twisted and wound into muslin by spinning; Sliver is drawn and twisted on a roving machine to make roving; a combing machine for carding fibers into combed slivers; a needle card machine for combining slivers; Needle drawing improves the structure of the sliver; further twisting of muslin on a ring spinning machine; the spinning machine is the main machine for spinning. The performance andnd quality of fine yarn comprehensively reflect each process of spinning technology.

What is the importance of the ring frame machine?

The spinning process is the final process of spinning, but also an important process of the textile factory. The total number of spinning processes is an important symbol for measuring the size and production capacity of the cotton textile mill. determines the production level of the company. The quality and consumption of fine yarn determine the spinning costs. The breakage rate of fine yarn is an important index for company valuation. Therefore, the spinning process can comprehensively reflect the production technology and management level of a cotton spinning mill.

The task of the spinning process

1. Draw

The supplied roving is pulled evenly and finely to the required number of special yarns.

2. Twist

Add an appropriate twist to the dragged whisk to impart specific physical and meto impart mechanical properties such as strength, elasticity, shine and feel.

3. Winding

The spun yarn is wound onto the bobbin in a specific shape for ease of transport, storage and further processing.

What is the ring framing process?

Ring The most common is the spinning machine. The common ring spinning machine is composed of a double-sided multi-spindle structure, mainly composed of a feeding mechanism, a stretching mechanism, a rotary winding mechanism, and a forming mechanism. The roving is unwound from the roving tube. The roving is fed through the roving frame and fed into the puller for drawing by the guide rod and the slow reciprocating motion of the guide horn. The drawn whisker is paid out from the front roller through the thread guide hook and through the wire ring and wound onto the spool firmly on the spindle. The spindle rotates at high speedt. The ring of wire is rotated at high speed on the steel collar by the strip of yarn with a certain tension. Each twist of the wire ring adds a twist to the whisk being pulled. Since the rotation speed of the wire ring is slower than that of the twine tube, the continuous performance is ensured. The twine strip of the front roller is wound onto the twine tube. The difference in speed between the ring of wire and the yarn tube is the number of turns per unit time of the yarn tube. Depending on the control of the forming mechanism, the steel collar plate will rise and fall according to a certain rule, so that the fine yarn will be wound into a certain forming yarn.

What is the disadvantage of ring frames?

Making spinning frame accessories is the first step in the textile industry chain. The quality of its products, the efficiency of production and the level of processing costs play a role in the wholen industrial chain plays an important role. Therefore, more attention is paid to the development of spinning technology and the promotion of new technologies at home and abroad. With the continuous development of spinning technology, there are currently two types of spinning technology in spinning production: one is ring spinning technology, the other is a new spinning technology, which is widely used.

Because of long working hours, there will be some Problems in the spindle position of the spinning machine, which need to be repaired by the maintenance staff, 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 facility. Eliminating these broken spindles is a long and tedious task, but reducing uneven yarn quality is extremely necessary. Most of these imperfections are associated with ring and spoke damage, pull differentials, and rollingen together deviation, yarn frame, etc.

What are the three types of spinning?

Common flyer spinning machines are generally divided into three categories: frame spinning machines, spinning machines and ring spinning machines. Frame spinning machines and spinning machines are discontinuous spinning machines. Ring spinning machines belong to continuous spinning machines. There are some differences in the spinning methods corresponding to these three roving spinning machines, and there are also many differences in performance.

According to Relevant studies show that the uniformity of these three spinning machines is relatively lower than that of the first two, but the spinning efficiency is higher than that of the other two. Each of these three spinning machines has its own merits.

The difference in spinning of different roving frames is due to the difference in spinning. The first two types of walking are horizontal, without control area length, without turning wrapsen, twisting without winding, the balance of twist is good, so the uniformity is much better , but its stretching range is too long.

The ring spinning frame twist is vertical, the twist balance time is short, so the uniformity is bad because the control zone is short, so there are much fewer broken endsproblem.

Due to the different working mechanisms, there are differences in the quality and efficiency of their production. For each company, different flyer spinning machines can only be selected according to the actual needs of production, to achieve the highest production efficiency.

How to distinguish the four yarns?Ring spinning yarn

All the yarn can be fully untwisted in ring spinning, and the yarn has no more firmness after turning it up:

Air spinning of yarn (spinning cup spiders)

As in the ring When spinning, all of the yarn cannot be fully untwisted. Only a few parts can be fully unwound. Therefore, once untwisted, the untwisted knots are not strong and the entire yarn breaks as soon as it is pulled:

Siro spun yarn

Siro spun all the yarn be completely unwound after the end of the twisted yarn has no strength

Spins of these four yarns Siro the only one that looks like a single yarn of two yarns; Spinning (when there are two pieces of roving are combined to give a single fine yarn); Good drying, fewer feathers, higher strength than ring spinning:

 

 

Yarn Vortex Spinning

After vortex spinning, the outer surface looks completely unge twisted but yarn core is not untwisted and still has great strength:

DW7040H Lab Ring Spinning Frame is used for spinning roving Yarn can be spun by drawing and ring spinning. It is the ideal system for Lhonor, research, etc.
