Working Principle of Twisting machine

Twisting machine is a textile machinery which twists multiple strands of yarn into one strand. The function is to process yarn or merged stranded yarn products into linear products for weaving and knitting. The spindle outside the twister body is connected with the motor output shaft of the circuit part, and the front end of the spindle is equipped with connectors, which correspond to the tap-changer.

The working principle of twisting machine: the ply yarn drawn from the cylinder, through the guide rod and the transverse guide device, from the guide roller output, through the guide hook and travelling coil around the tube. 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 horizontal form, and the ply yarn pulls the bobbin from the side and turns back. In order to reduce the end breakage caused by excessive tension during unwinding of single yarn, a conical cylinder is used to tightly cover the insert spindle, and the single yarn is pulled out axially from the respective end of the tube to realize the coalescence 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 to 8 ingots one section, full-length mosaic. Each spindle of the upper roller is driven by self-weight and friction of the lower roller. The composite yarn has a certain winding method on the roller, so that the yarn and the roller have enough long friction surround arc 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 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, the water is first applied, which 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. The ring plate can increase the density and capacity of the roll-up if it is lifted and lowered slowly in a single way. 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.

That's how the twister works. Twister is mainly used in twisting and plying engineering of cotton yarn, chemical fibre, silk and glass fibre.

Overall, this machine is an essential tool for blacksmith shops that produce doors, windows, and handrails on a large scale. Its ability to reduce costs by more than 50%-80% makes it a highly cost-effective option.

When using the LC120 hydraulic decorative iron pipe iron tube twisting machine, special attention should be paid to the thickness of the round tube. The machine is only capable of processing round tubes with a thickness of up to 2.5 mm.
