In recent years, after repeated market research, Pacific Electromechanical Shanghai Second Textile Machinery has successfully developed a new generation of highly automated and intelligent technology in the process of collaboration with Austrian B&R Industrial Automation Company Shanghai Branch and related cotton spinning enterprises. And digital products. Two of the electrical digital technologies have unique features: First, the tension control method of the new roving frame replaces the original mechanical iron cannon with an electronic iron cannon, and uses B&R's advanced PPC program controller to accurately calculate the motion formula and accurately control the Adjust the rotation speed difference of the winding motor to adjust the tension of the roving; Secondly, it has the function of power-off synchronization, using the characteristics of motor power generation, so that the generated electric energy can make the PCC program controller continue to work for a period of time, and can accurately control the frequency conversion. The synchronization parameters of the machine enable the winding motor to stop stably and synchronously, which not only maintains the original tension of the yarn, but also does not affect the normal production of the user.
In the past two years of user visits, the innovative features of the EJK211 roving machine digital technology have been fully affirmed by users. The Eé„„JK211 roving machine applies high-tech such as field bus, computer control and opto-mechatronics to the roving frame, which improves the level of mechatronics. The product's performance has reached the level of similar foreign products. Its four motors can directly drive the new control system of the flyer, bobbin, roller and dragon ribs, and the four inverters are controlled by the computer to realize the speed regulation and synchronous transmission, so that the spindle speed of the machine can reach up to 1500 rpm. The degree of flexibility and intelligence of the spinning process is improved. The new transmission mechanism of the flyer and the bobbin of this model uses a timing belt to form a 6-spindle flyer and a 3-spindle tube into a transmission group, which makes the structure simple and compact, and can be easily adjusted and synchronized by the tensioning pulley. The tension of the belt reduces noise and vibration, improves the spinning speed and the stability of the transmission, and improves the working environment. In addition, the machine adopts high-efficiency motor and DC common bus control scheme, which makes the synchronous motor run synchronously with high precision, and can ensure the spindle speed is running at 1500 rpm. The power consumption of the whole machine is less than 10 kW. obvious. The machine adopts touch screen human-machine dialogue, intelligent configuration of process parameters, and the adjustment of roving tension adopts full digital segmentation control system, which greatly facilitates the adjustment of roving tension under different varieties and different conditions.
After the exhibition of large-scale textile machinery exhibitions at home and abroad, the EJK211 roving frame produced by Pacific Electromechanical Shanghai Second Textile Machinery has been known by more and more users, and has a group of important customers in Shandong, Henan and other textile provinces. It has achieved the established goal of selling more than 100 units in Shandong and other regions. â–¡ Liang Jianrong
EJK211 roving machine adds highlights to digital spinning machine
The new generation of digital four-motor variable frequency drive EJK211 roving machine independently developed by Pacific Electromechanical Group Shanghai Second Textile Machinery Co., Ltd. has added new highlights to China's digital textile machinery. The new roving frame with independent intellectual property rights uses four new motors to directly drive the new control system of the flyer, bobbin, roller and dragon ribs, and the computer controls the four inverters to synchronize drive according to the set process curve. The level is at the leading position in the country.
