Operating Principle of Twisting Machine

Twisting machine is a kind of textile mechanical equipment that twists multiple strands of yarn into one strand. The function is to process the yarn or folded yarn products into linear products for weaving and knitting. The utility model comprises 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. The front end of the spindle is provided with a connector which corresponds to the tap changer.

Working principle of twisting machine: the plied yarn drawn from the bobbin is output from the yarn guide roller through the yarn guide rod and the traverse yarn guide, and is wound on the bobbin through the yarn guide hook and the steel wire coil. When the spindle drives the bobbin to rotate together, the yarn drives the steel ring to rotate on the annular ring to twist the yarn.

Most of the bobbins on the bobbin frame are looped on the inserting spindle in a horizontal way, and the plied yarn pulls the bobbin to rotate from the side and unwinds. The combined twisting machine is fed with a single yarn package. In order to reduce the end breakage caused by excessive tension during single yarn unwinding, a cone shaped package is tightly sleeved on the insertion spindle, and the single yarn is axially led out from the respective package ends. The feeding frame is used for merging. The doubling and twisting machine can save the doubling process and is generally only suitable for spinning double ply yarn with low quality requirements. The guide roller is usually a pair of smooth round rollers. The lower roller is a 6-8 ingot section, which is spliced with its full length. Each spindle of the upper roller is pressurized by its own weight and driven by the friction of the lower roller. There is a certain threading method for the plied yarn on the roller, so that there is a long enough friction surrounding arc between the yarn and the roller to ensure that the roller conveys the yarn to the twisting area at a uniform speed. Some of them use two lower rollers, or even two pairs of rollers, on the specially spun thick ply yarn or multi twist twisting machine to adapt to the high twisting tension and achieve the goal of uniform yarn feeding. In the roller part, some twisting machines are equipped with a self stop device for breaking ends. Some twisters are called wet twister because there is a water tank under the yarn guide rod, and the plied yarn is wetted before twisting. Wet twisted yarn has the advantages of high strength and smooth surface, but the roller and yarn guide parts need to use rust proof materials.

The winding and forming mechanism of ring twister is mostly the same as that of ring spinning frame. The ring plate is driven by the forming cam to rise and fall in a short range. After each rise and fall, the position rises to a certain height, so that the pipeline can be wound into a conical cross winding package. Double bobbins are often used when spinning thick ply yarn or on a multi twist twisting machine. The ring plate can increase the density and capacity of the package by a single, relatively slow, whole process lifting. The main difference between traditional fancy twister and general twister is the yarn feeding part. Different types of fancy yarn are spun, and the mechanism and movement of the yarn feeding part are also different.

The above is the working principle of the twisting machine. The twisting machine is mainly used in cotton yarn, chemical fiber, silk, glass fiber and other twisting and stranding projects.
