What's Yarn Twisting Machine?

Yarn twisting machine is a textile machinery that twists multiple strands of spun yarn into one strand. The function is to process the yarn or the combined plied yarn products into linear products for weaving and knitting. It consists of a twisting machine body and a circuit part. The spindle outside the twisting machine body is connected with the motor output shaft of the circuit part, and the front end of the spindle is provided with connecting pieces corresponding to the tap switch.

Yarn twisting machine is suitable for: cotton yarn, cotton, chemical fiber, embroidery thread, nylon, polyester, rayon, sewing thread, silk, glass fiber and other twisting and plying projects.

The feeding method of the twisting machine: the flat tube is fed into the pure twist creel or the cone tube is fed into the parallel twist creel, the parallel yarn or pagoda yarn (wooden tube or paper tube) is fed, and the pure twist creel is fed.

What's Fancy Yarn Twisting Machine?

The fancy yarn twisting machine is a twisting machine for spinning fancy yarns. It is equipped with a computer, which can program the yarn feeding movement of the feeding part according to the requirements, and can produce fancy yarns of various styles and structures.

The traditional fancy twisting machine belongs to the "ring twisting machine", which is characterized in that the feeding movement law of the feeding part of the mechanism varies with the requirements of the fancy thread. For example, in spinning loop yarn, the feeding part is two pairs of rollers with different speeds. One of the pair of rollers is overfed and variable speed. When the two yarns are combined and twisted, the loop effect will occur. Modern fancy twisting machines are equipped with computers, which can program the yarn feeding movement of the feeding part according to the requirements, and can produce fancy yarns of various styles and structures. Fancy twisting machines can also use "hollow spindles" for twisting. For example, the feeding part is three pairs of rollers, one pair feeds the core yarn, and the other two pairs are drafting mechanisms. The slivers or rovings are drawn as decorative yarns, and the movement rules of each sliver are controlled by the computer according to the requirements. The fixed yarn package is wrapped around the hollow spindle and rotates together with the spindle. After being drawn out, it passes through the hollow tube of the spindle together with the core yarn and the decorative yarn. The hollow spindle drives the three yarns to rotate together. , Fixed yarn fancy yarn.

What's Ring Twisting Machine?

Ring Twisting Machine

The plied yarn drawn from the bobbin passes through the yarn guide rod and the traverse yarn guide, and is output from the yarn guide roller, and is wound on the bobbin through the yarn guide hook and the traveler. When the spindle drives the bobbin to rotate together, the yarn drives the traveler to rotate on the annular ring to twist the yarn.

Most of the bobbins on the bobbin creel are looped on the spindle in a horizontal form, and the plied yarn is pulled from the side to rotate the bobbin and unwind. The doubling and twisting machine is fed with a single yarn bobbin. In order to reduce the breakage caused by excessive tension when the single yarn is unwound, the tapered bobbin is tightly sleeved on the insert spindle. The feeding creel part realizes merging. The doubling and twisting machine can save the doubling process, and is generally only suitable for double-stranded yarns with low spinning quality requirements. The yarn guide roller is usually a pair of smooth round rollers. The lower rollers are 6-8 spindles in one section, and are inlaid along the entire length. Each spindle of the upper roller is pressurized by its own weight, and is frictionally driven by the lower roller. The plied yarn has a certain method of threading and winding on the roller, so that the yarn and the roller have a long enough friction surrounding arc to ensure that the roller can deliver the yarn to the twisting area at a uniform speed. In the special spinning of thick strands or double twisting machines, some use two bottom rollers, or even two pairs of rollers, in order to adapt to the high twisting tension and achieve the purpose of uniform yarn feeding. In the roller part, some twisting machines are equipped with a self-stopping device for broken ends. In some twisting machines, there is a water tank under the yarn guide rod, and water is applied to the plied yarn before twisting, which is called a wet twist twisting machine. Wet-twisted threads have the advantages of high strength and smooth surface, but the rollers and yarn guides need to be made of rust-proof materials.

The winding forming mechanism of the ring twisting machine is mostly the same as that of the ring spinning machine. The ring plate is moved up and down in a short stroke by the forming cam, and the position rises to a certain height after each lift, so that the pipeline is wound into a conical cross-winding package. Double-sided bobbins are often used when spinning thick strands or on multi-twisting machines. The ring plate can be lifted and lowered in a single relatively slow whole process, which can increase the density and capacity of the package. The main difference between the traditional fancy twisting machine and the general twisting machine is in the yarn feeding part. Different types of fancy threads are spun, and the mechanisms and movements of the feeding part are also different.
