The configuration of the automatic winding machine includes air splicer, mechanical splicer, electronic yarn clearer, nickel alloy cast iron drum, mechanical anti-overlap device, balance, anti-shock, tension device, fixed length and sizing device, and single spindle frequency conversion Speed ​​regulating device, waxing device, machine head comprehensive monitoring system, swimming blowing and suction device, etc.

1The development of new automatic network machines

At present, most of the traditional automatic winding machines do not have yarn position control to capture the

The process of yarn starting usually relies on time setting. After catching the yarn end, the extra equipment

Setting the time will allow more length of yarn to continue to be sucked in. On the contrary, if the setting

If the time is too short, the success rate of head catching will be reduced. For maximum optimization of yarn splicing

Control and reduce the amount of yarn retrieval. The most advanced modern automatic winding machine uses yarn end transfer

Sensor control technology. The yarn end sensing device in the automatic winding machine detects the suction

Once the yarn end is captured, the sensor can immediately send a signal

Carry out splicing action, otherwise the previous action will be maintained until the yarn end is captured.

Continue to the next action. The design and manufacturing accuracy and stability requirements of this type of equipment are very high.

It is one of the main textile equipments that have been researched and developed by various advanced countries in recent years, and it is also the

The main technical transformation content of many textile enterprises is to improve product quality.

The automatic winding machine has achieved comprehensive single-spindle control. According to the type of yarn processed,

Depending on the quality, energy consumption fluctuations are different. At this stage, all the changes are adopted

Frequency motor, central computer setting control. In actual processes, in order to ensure that the

Under the condition of not exceeding the minimum process requirement limit, the parameter setting values ​​of the rolling machine are all

Generally set to higher. The most advanced modern winding machines use variable frequency motors.

Basically, a fully automatic computer negative pressure monitoring device is used, so that it can be adjusted according to consumption.

The air volume automatically adjusts the speed of the suction motor. When there are no or only a small number of spindles, the suction

Low-speed operation of the wind turbine can reduce the power consumption of the wind turbine by more than 50%;

When many spindles operate at the same time, the frequency conversion motor speed increases rapidly to ensure accurate negative pressure.

Maintain at the set value so that the yarn end can be captured quickly. After this period, the system will automatically

Return to low speed state. Therefore, the working negative pressure of the automatic winding machine is set at

The position closer to the extreme process requirements makes the corresponding average motor speed effective.

Reduce, so that the average power consumption of the whole machine can be reduced by about 20%, thereby achieving the purpose of energy saving.

What should I do if it’s due?

Italy's Savio (Savio) ORION? M/L model adopts computer intelligence

The winding system adopts electronic modulation and anti-overlap function. It self-adjusts according to the equipment operating parameters.

The complete electronic "start? stop" adjustment method can avoid useless acceleration.

In the process, the working amplitude and frequency are set on the comprehensive monitoring system and the tank is driven directly

It can also ensure the transmission ratio between the cylinder and the grooved cylinder and prevent overlapping.

1.2 Yarn splicing system

Air-twisted joint technology is the development trend of contemporary automatic winding machines, and the joint quality

good. The air splicer is an important part of the automatic winding machine. Air lay joint

It can reduce the holes in knitted fabrics. Due to the large knots, ordinary splice yarns are used in the production of high-density knitted fabrics.

When the product is removed, the warp will be broken at the steel foil or there will be large flaws on the cloth surface. Currently available

Splicing technology has been widely used in splicing any raw material, any variety, and yarn count. It is

An integral part of the winding process.

The appearance quality of the package yarn processed by the winding machine is further improved, and the joints are strong

Achieve the average strength of the yarn. Not only improves the appearance and inner appearance of cheese and fabrics,

In terms of quality, it also creates conditions for increasing the speed of the ring spinning machine, such as reducing the straightness of the steel ring.

Dramatically increasing the spinning speed, the spindle speed of contemporary ring spinning machines has reached as high as 25,000

r/mmin, which is closely related to the quality of the air-twisted joints used by the rolling machine to achieve no joint marks.

The automatic winding machine produced by Savio company has a splicer in addition to the mechanical twister.

Except for the production equipment, all other equipment and connectors are provided by the Italian MESDAN company.

The quality is better. The SMAROM automatic splicing machine produced by Jingwei Co., Ltd. Qingdao Hongda adopts a new type of air splicer, which can meet the needs of single yarn, strand and elastic core-spun yarn splicing processes by simply replacing different splicing chambers. In addition, we also have special technology splicers such as water-controlled document splicers to adapt to the splicing requirements of special varieties such as hemp and high-twist yarns. 1.3 Winding tension control system The tension disc tension device is a tension device that can control the winding tension. The winding tension is generally large and has small fluctuations. The part of the device that contacts the moving yarn is long and plays an important role in increasing the hairiness of the yarn. The winding tension can be set in the machine head computer before production. The same tension value can be set for each spindle position, or different tension values ​​can be set in sections to meet the needs of multiple varieties. In addition, if the winding tension fluctuates severely and exceeds the range, the machine control system tension device controls the moving yarn to automatically adjust the yarn tension and make it constant. Autoconer5's Autotense FX yarn tension adjustment system detects it through the tension sensor Winding tension, adjust the tension electromagnet voltage to achieve the purpose of changing the tension disk pressure, thereby changing the winding tension. The QRION? M/L type winding tension control system uses a tension sensor installed on the upper part of the electronic yarn clearer to detect the winding tension. When the winding tension exceeds the set range, the single-spindle computer-controlled tension system changes the pressure on the yarn to achieve Constant winding tension. If the winding tension exceeds the set range and the automatic adjustment of the yarn tension device cannot be realized, the preset speed increase or deceleration curve can be started to change the drum speed to maintain the winding tension in a timely manner.
