The ply yarn drawn from the drum is output from the guide roller through the guide rod and the transverse guide device, and is wound around the drum tube through the guide hook and the traveler. When the spindle drives the tube to rotate together, the yarn pulls the traveller to rotate on the ring ring ring and twists the yarn.
The bobbins on the bobbin frame are mostly looped on the insert in the form of horizontal, and the ply yarn pulls the bobbin to turn from the side and back. In order to reduce the end breakage caused by excessive tension during single yarn unwinding, a conical cylinder is tightly sleeved on the insert spindle, and the single yarn is pulled out axially from the respective end of the tube, thus realizing the merging in the feeding frame. The combined twisting machine can save the process of yarn drawing and is generally only suitable for double strand yarns with low spinning quality requirements. The guide roller is usually a pair of smooth rollers. Lower roller is 6 ~ 8 ingots one section, full-length mosaic. Each spindle of upper roller is driven by self-weight and friction of lower roller. The composite yarn has a certain winding method on the roller, which makes the yarn have enough friction arc with the roller to ensure that the roller conveys yarn to the twisting area at a uniform speed. Some of them use two lower rollers or even two pairs of rollers to adapt to the high twist tension and evenly feed yarns on the special spinning thick strands or twisting machines. In the roller part, some twisting machines are equipped with self-stop device for broken ends. Some twisting machines are equipped with a water tank under the guide rod. Before twisting the ply yarn, it is called wet twisting twisting machine. Wet twisted yarn has the advantages of high strength and smooth surface, but anti-rust materials are needed for rollers and guide frames.
The winding mechanism of ring spinning twister is mostly the same as that of ring spinning frame. Ring plate is driven by forming cam for short-range lifting. After each lifting, the position rises to a certain height, so that the pipeline is wound into a conical cross-winding package. Bilateral barrels are often used in spinning thick strands or in twisting machines. Ring plate can increase the density and capacity of roll-up if it is lifted and lowered slowly. The main difference between the traditional fancy twister and the general twister is the yarn feeding part. The types of fancy yarns are different, and the mechanism and movement of the yarn feeding part are also different.
