　　 New generation of high speed and high efficiency DC motor

Compared with AC motor or modern BLDCM, the new generation DC motor has greater output power and torque. By controlling the commutation time (commutation angle), the brushless motor can achieve the effect of brush shifting, which is beneficial to improve the high speed performance of the motor, and has a very high efficiency in a wide speed range and load torque range; it has the advantages of small volume, light weight and low temperature rise. The new generation of DC motor has the characteristics of traditional DC motor, so it has larger starting torque and better dynamic characteristics than BLDCM. The armature total current and branch current are DC current, so it has the advantages of simple control and convenience. It has the advantages of small torque ripple, smooth operation, low noise and high speed accuracy. The bus current is DC current, and the electromagnetic compatibility of the motor system is good.

In the environment of energy saving and emission reduction, under the fierce competition of textile industry, it is an indisputable fact that the demand for high-end textile equipment with high efficiency, high quality, high degree of automation and energy saving is increasing rapidly with the increasing cost of personnel and the continuous improvement of yarn quality.

　　 User voice

New trend of automation development of Lida textile machinery

At present, the development direction of textile equipment mainly includes high-speed, continuous, short-range, intelligent, high quality, high speed and high efficiency. The flexible transportation system includes automatic roving doffing and automatic roving between roving and spinning frames. It recommends the integration of roving tube automatic cleaning device. In the automatic yarn clipping device of spinning frame, there is no need for bottom yarn, less flying flowers, fewer yarn faults and breakage, less maintenance and cost saving.

In the monitoring of single spindle of spinning frame, the LED lights on the sensor often indicate the broken ends and the spindle slips in the case of the spindle level of the truck guide system. On the body level, the LED lights on each section (24 spindles) indicate that there is an accident in this section to be processed; at the machine level, the rear end of the vehicle is equipped with a display light to guide the driver. Single spindle LED lamps can quickly identify the need to maintain spindles, identify slipping spindles, separate defective yarns, and repair existing problems.

In the R40/R60 seamless joint system, when the joint is ready, the original yarn enters the center of the twisting disc, the negative pressure of the air storage unit starts, the seed yarn enters the center of the twisting disc, the length of the yarn needed for the connection is stored in the air storage unit; when the joint is started, the fiber flow begins to enter, and the negative pressure of the air storage unit is turned off, and the seed yarn head is sucked into the spinning cup to coagulate and fiber. When the yarn is in contact with the seed yarn, the spinning process starts and the yarn is drawn out of the spinning cup.

　　 Promoting the development level of textile machinery automation with R & D as the source

The electrical control of textile machinery has undergone electrification (Electrical instead of machinery) to intellectualization (computer control), and then to automation (networked unmanned operation). The intelligent blowing carding unit of our company is based on intelligent control theory, which integrates frequency conversion, sensing, network control and other technologies. It realizes continuous automatic production of raw cotton, loosening and removing impurities, and even mixing to uniform striping. At present, the intelligent cleaning and carding equipment realizes automation, high speed, continuous, mechanical and electrical integration, intelligent production line, achieves high quality and high yield, reduces labor intensity, improves labor productivity, improves labor environment, saves personnel, saves floor area and saves energy consumption. The company's intelligent blowing carding unit has formed a high quality pre spinning equipment manufacturer with completely independent intellectual property rights, and has enhanced the competitiveness of the domestic spinning machine equipment, and has become an international competitive advantage industrial chain.

In the JSR668 computer roving machine, the leading four axis multi motor group variable frequency synchronous transmission system. The flyer and bobbin are driven directly by a multi motor through the synchronous belt. Each group of 24/32 spindles and bobbins is driven by a motor, and the user can configure the spindle number according to the needs. The dragline lifting system adopts direct conversion of the variable frequency decelerating motor, reverses the traditional reversing mechanism, makes the commutation accurate, and greatly simplifies the mechanism, facilitates the adjustment and maintenance of the process, and reduces the capacity. The fault prone parts greatly improve the reliability of the equipment.

At present, the main part of the spinning machine is intelligent single machine (mostly using the inverter +PLC+ touch screen). There are few bus control modes, and many process equipments are difficult to realize the standardization of the network. Future goals include: establishing standards for future digital plant (including software application platform); digitizing each single machine; realizing automation and informatization in textile industry. {page_ Break}
