Semi Automatic Rotor Spinning Machine Makes Production More Flexible.

In recent years, with the development of manufacturing technology, many semi-automatic rotor spinning machines have been recognized by customers. For example, in recent years, BT923, 924 (R923, R924) and other semi-automatic rotor spinning machines developed by Lida and Czech company have applied new spinning machines, the quality of products has improved significantly and the adaptability of products has increased. In addition, since the new semi-automatic rotor spinning machine is equipped with a fully automatic connection device, the starting time is only 10% of that of the ordinary rotor spinning machine, and the energy consumption is also lower than that of the ordinary BD series rotor spinning machine 10%.

　　 Can increase capacity 10%~15%

The main advantages of BT923 semi-automatic spinning machine produced by Lida are high efficiency, man-machine conversation and C-120 spinning. In addition, the joint system, electronic yarn clearer and spinning adaptability of this spinning machine are also very good.

The characteristics of BT923 semi-automatic rotor spinning machine's man-machine conversation engineering and convenient operation are as follows: its online spinning quality monitoring system can increase production capacity by 10%~15%. When the number of spinning spins is less than 14.5tex (40 British branches), the speed of the rotor can reach more than 110000 revolutions per minute, and the output line speed is above 200 m / minute. Each device has 360 rotor spinning heads, and the distance between the spinning boxes can reach 230 millimeters.

As the BT923 semi-automatic spinning machine works more than the automatic rotor spinning machine (with R40 or Auto360 of the robot), the design of semi-automatic spinning machine should consider the convenience of manual operation as much as possible, so as to reduce the burden of the operator and make the whole production process simple and easy to operate. 1 BT923 semi-automatic rotor spinning machines occupy 1 operators, so the spinning route design of each spinning head of rotor spinning machine has great influence on the labor intensity of the operator. Compared with the original semi-automatic rotor spinning machine, the new semi-automatic rotor spinning machine has the characteristics of low labor burden and high production efficiency. The height of the BT923 semi-automatic rotor spinning machine is raised to 42 inches and the head distance is 230 millimeters, which can facilitate the discharge and exchange of 18 inch cylinders. At the same time, operators can also directly deal with problems arising from the production process without using other tools. This large barrel production mode can reduce the number of tube changing and reduce manual labor burden, so as to reduce the number of yarn joints and improve the yarn quality. The BT923 rotor spinning machine is equipped with two sets of conveyor belts, not only for conveying bobbins and cheese, but also for reducing operator burden. Moreover, the two transmission belts can also be used for temporary storage of the yarn, so that the operator can work more flexibly.

C-120 spinning machine is a key part of BT923 rotor spinning machine. The C-120 spinning machine has the following advantages: the spinning device is based on the central centralized suction system, so that the air and rotor do not need to open holes; the ceramic rotor bearing has the characteristics of wear-resisting and stable operation, and can reduce the broken ends of spinning, and can obtain the best profit under the condition of high speed rotary condition and under the condition of certain cotton sliver supply. The C-120 spinning machine can remove trash particles to the maximum extent, thereby purify rotor yarn, and collect the least effective fibers in the waste. C120 spinning machine is the latest design of the best fiber transmission channel and components, spinning device installation and removal of convenience, with only a few tools.

　　 Joint quality Marked improvement

BT923 semi-automatic rotor spinning machine with automatic control system, automatic joint system and other automation systems, can greatly reduce the intensity of artificial labor.

The automatic control system can automatically adjust the pressure level according to the requirement of the operator. The automatic control system of the filter can prevent the deviation of the vacuum pressure, reduce the loss of the vacuum degree, and automatically compensate for it. The vacuum pressure value can be set low, thereby saving energy. The vacuum regulation and control is controlled by the Autovac system automatically. The automatic control system ensures a stable vacuum condition. The system can automatically adjust the pressure level according to the operator's requirement.

The Amispin connector used in the BT923 rotor spinning machine is a controlled electronic joint device, which is combined with QTOP to form a uniform and stable joint action to realize the quick restart of the machine. Compared with the BT903 rotor spinning machine, the connector has made remarkable progress. It is not only superior to other semi-automatic rotor spinning machines, but also easy to operate. The Amispin is placed in the input roller, which can accurately control the feeding time of the cotton sliver and the output time of the rotor spun yarn, and completes the operation of the yarn joint to ensure the quality of the joint. With the maximum output speed of BT923 at 200 m / min, high quality rotor spun yarn can be produced with excellent joint quality.

The BT923 rotor spinning machine is equipped with an annular pressure compensator. When the machine is started, it is wound into the acceleration state. The desired yarn is drawn out of the rotary cup, and the circular compensator is applied. The yarn drawn from the rotor cup is applied to make the yarn undamaged and no air ring formed. Even if the high count yarn is produced, the joint quality of the Qtop system on the BT923 can be guaranteed. Qtop can remove damaged fibers from the sliver by means of pneumatic force. During the opening process, the short fibers are drawn from the loose part and are joined to the new ideal length fibers in precise time. (other semi-automatic adaptor is too slow to prevent the damaged short fibers from being removed quickly, and at the same time, it can not guarantee the continuous flow of fibers through the joint system. The joint quality of the machine is good, basically no joint mark is found, and the strength of the joint is similar to that of the rotor yarn produced on line.

BT923 can also install a new photoelectric electronic yarn clearing system IQPLUS of Lida, which is more suitable for high speed and more discriminating ability than the previous yarn clearer. The new photoelectric electronic yarn cleaning system can be installed on the machine control panel. Its sensor and yarn clearer can be automatically set according to the number of yarns. The yarn can be directly evaluated by sensors, including the processing function of the yarn cleaning system.

　　 Do spinning Expansion of spinning performance

The BT923 and BT924 semi-automatic rotor spinning machines produced by Lida and Czech company have the advantages of high speed, good spinning quality and strong adaptability, and their automation level is relatively high in semi-automatic rotor spinning machine system, which is very suitable for China and the three world countries. The BT923 rotor spinning machine is a single head transmission system, so spinning is very flexible. Two different yarns can be processed on a rotor spinning machine at the same time. The two sides of the rotor spinning machine are independently driven, and both sides can be conveyed with full conveyor belt. The rotor spinning machine has many uses, it can be used to produce slub yarn device, so that the rotor spinning machine has the function of producing slub yarn.

The slub yarn device of BT923 rotor spinning machine can produce slub yarn economically. This slub yarn is mainly used for weaving denim and other fabrics. The slub yarn device is completely connected with the rotor spinning machine circuit. It does not need a separate circuit device. The parameters of the machine are transmitted from the computer to the rotor spinning equipment by the data memory card. The program software has many functions, including the precise setting of slub length and spacing, data storage, analysis and calculation, so as to set the machine parameters again.

The slub length and spacing setting procedures on slub yarn can be regular or irregular. Software can make the slub 100% repeatable. There are 8 different sluice in programmable software, and users can set up separate sluice program in software program according to need. The newly established slub procedure can be easily transmitted to the machine through SLUBLINK IC card. Slub yarn production is usually carried out on 280 rotor spinning machines. The production of slub yarn and normal yarn can be conveniently realized by means of machine electronic control panel control.

Because of the high yarn quality of the automatic rotor spinning machine and semi-automatic rotor spinning machine, the yarn evenness CV% value is better than that of the ring yarn, and the yarn defects and hairiness are less than that of the ring yarn. Therefore, the weaving efficiency of the air-jet loom is higher than that of the ring yarn.
