Cone winding machine demystified: your ultimate reference

What is a cone winding machine?

Cone winding is the first preparation process before weaving. Its task is to process the tube yarn or skein yarn from the spinning mill into specific requirements on the winding machine. As the final process of spinning and the first process of weaving, winding plays the role of a \"bridge\" and therefore plays an important role in the textile field.

The speedSpeed ​​of cone winding machine

The speed of cone winding machine should be determined according to the yarn quality. The better the yarn quality, the less deterioration of the tubular yarn. On the contrary, the deterioration increases. At the same time, the winding speed is closely related to the unwinding tension of the yarn, and the unwinding tension is smaller at low speed than at high speed. In the whole unwinding process, the large and medium yarn tension is relatively small, and less unwound The winding speed can be a little higher, but when unwinding the small yarn part, the unwinding tension doubles, which makes unwinding easier, which also limits the improvement in winding speed. Therefore, for large and medium yarns, the speed should be improved, for small yarns, the speed must be properly reduced so that the taactual speed of winding is reached.

From experience, when spinning medium and fine grades, we generally choose +30% as the percentage of the initial VSS system speed change, 60% as the final speed change percentage, 70% as the change percentage. It can be seen that when spinning different number variants, the speed and tension change as the number changes. The lower the number, the lower the speed and tension. The yarn count For yarns with a fine gauge, the value is smaller than for yarns with a thick gauge. When a high-speed unwinding speed is applied, yarn defects with long details are easy to occur, deteriorating yarn quality and leading to deterioration of CV value, hairiness, strength and other indices. In severe cases, an accidental failure can occur, resulting in ayarn increase, and then affect the production efficiency of enterprises.

When choosing the yarn winding speed, other factors are also taken into account, such as supply problems and the more important yarn index deterioration. Under normal circumstances, it is reasonable to keep the CV value deterioration degree within 0.5%, and the -30% details of the yarn should not exceed 200/km, and this value will increase as the yarn size decreases.

The goal of a cone winding machine: Change the pack to increase the amount of yarn in the pack:

A larger spool is made by connecting smaller volumes of yarn (or skeins) through a link winding sleeve, with a spool being the equivalent of more than 20 threads. The bobbin can be used for warping, twisting, winding, dyeing, wefting on shuttleless looms and knitting yarn. When the cane yarn is used directly in these processes wird, downtime will be increased too much, affecting the improvement of production efficiency and product quality. Therefore, increasing the winding capacity is a necessary condition to improve the productivity and quality of the latter process.

Eliminate the yarn defects and improve the yarn quality:

The yarns produced by cotton mills have defects and impurities, such as e.g. B. thick knots, details, double yarns, weakly twisted yarns, knots, etc. The yarn cleaning device is used to inspect the yarn during winding and remove defects and impurities that affect the quality of the fabric, yarn uniformity and finish to reduce yarn end breakage in the later process and improve fabric appearance. This is most useful in the case of yarn defects and contaminants need to be removed during the winding process aseach coil works independently, allowing the other to continue its work, e.g. B. with a bra,

Types of winders or inary yarn winders

They can be divided into tubular yarn feed type, skein yarn feed type and bobbin yarn feed type. The tube feeding type is used in most situations, the hank feeding type is only used in the yarn-dyed preparation process, and the bobbin feeding type is used in the inverted cylinder.

At present, Chinese textile companies commonly use household slow-speed machines (tube yarn feeding is generally 550 -750 m/min, skein feed 140-160 m/min, bobbin). yarn feeding type is 600-1 200m/min), low power, low level of automation, more labor and average winding quality.

The yarn is unwound from the tube yarn and guided to the guide plate through the yarn guide rod then passes through the groove of the Sdisc tensioner, the yarn cleaning device and the tension rod, leads to the grooving drum, and finally winds onto a bobbin on the grooving drum.

Automatic yarn cone winder

The automatic yarn cone winder replaces manual operation with electromechanical integration operation to complete the tube changing process and automate the to realize broken connection. Modern automatic winders have automatic tension control, anti-stacking, electronic yarn cleaning, anti-hair and fiber removal, etc. Other functions enable man-machine dialogue through the touch screen, adjust the process parameters, and display the quality status of each individual ingot in real time.

The components of the yarn winding machine

The yarn winding machine is mainly composed of the bobbin transfer device, bobbin winding forming device, anti-stacking device, electronic yarn cleaning device, yarn tensioning device, automatic Gspeed control device, etc. Automatic winding machine is the latest generation of textile machinery, integrating machinery, electricity, instruments and gas. The tubular yarn is The yarn is wound into a knotless tube and defects are removed during the winding process.

The combination of automatic yarn cone winder and powerful electronic yarn clearer shows the advanced automatic winder. In addition to the traditional automatic winding machine, most of them do not have yarn position control and depend on timing when grasping yarn head. After capturing the twine head, the excess settling time will cause more twine length to be further inhaled, on the contrary. If the settling time is too short, the success rate of the capture head will be reduced. Advanced mode is enabled to optimize twist control and reduce the amount of twine rewindautomatic winder uses yarn head sensor control technology.
