As an important textile equipment, the roving machine is related to the speed and quality of the spinning of the entire textile mill, and plays a role in the textile factory. The traditional roving frame is driven by a single main motor, which performs the processes of drafting, winding, and forming of the sliver through complex mechanical transmission. In the past, equipment was noisy, mechanically complex, difficult to maintain, and more difficult to upgrade in terms of speed.
According to the characteristics of the textile machine and the technical advantages of Delta products, Zhongda Jinan Branch has designed a unique technical solution of three-frequency conversion and four-frequency conversion. After repeated trials, it successfully launched into the market.
This system mainly uses Delta PLC (DVP-48EH00R) as the core of control, which can process calculation and comprehensive control; use three or four inverters to realize the transmission of spindle, winding, dragon rib, roller and other shafts. The human-machine (HMI) friendly interface enables operation setting and monitoring functions; the encoder can be combined with the V-Series variable frequency PG card to achieve synchronous operation of each axis and feedback to the PLC's high-speed counting channel. Complete the forming function of the roving.
In addition, taking into account the current situation of frequent power outages in China's vast areas, Zhongda Dentsu has added anti-power-off measures in the design of the three (four) variable frequency common DC bus – even when the external power is suddenly cut off, the axes can be guaranteed. Simultaneous parking can effectively prevent more than 100 yarns of the roving frame from being pulled off during power failure.
Through long-term testing and application practice, the spinning machine with Delta products performs well: the speed of the flyer is up to 1500 rpm, the maintenance is simple and the operation is user-friendly. With the superior performance of the system integration and outstanding cost performance, Delta automation products have been well received in performance and control.
A series of successful system integration solutions have convinced that Delta can not only provide high-performance electromechanical products, but also provide high-tech solutions with high added value. Following the successful development of the 485 three-inverter model, the 487, 477, 457 and other models have been developed successively, and the strategic cooperation with users has been fully launched. The resulting radiation effect will definitely enhance the influence of Zhongda Dentsu in the textile industry, lead the market and accelerate the upgrading of textile machinery.
Delta products promote the upgrading of roving frames
With the development of social economy, the development of China's textile industry is entering the spurt stage; the upgrading of various textile equipment has brought unprecedented opportunities for textile machinery manufacturing enterprises. Recently, Zhongda Dentsu Jinan Branch has reported good news – the newly developed roving machine has been favored by a textile equipment manufacturer in Qingdao and is now available in volume.
