At present all kinds of domestic whole machine has basically reached the domestic textile enterprises in whole by the requirements of the production, but throughout the warp tension control, warping speed, the whole automatic control, and foreign equipment still exist certain disparity. Although foreign advanced warping machine and the high yield warping machine still has the high price advantage, but with in recent years domestic whole machine of rapid development, the whole equipment of main technical parameters and technical features were close to the level of similar foreign models.The intelligent positioning of the whole warp machine positioning machine by the machine aimed at high speed and speed of the whole machineThe modern whole warp machine can be generally divided into different kinds of machine and sub - warping machine.. Them in batches throughout the machine generally exhibit to the high-speed development of the trend and the design line speed has reached 1000 meters / minutes; beam transmission basically uses the exchange frequency conversion velocity modulation motor direct drive, and the constant line speed and the constant tension winding; beam, a pressing roller, a yarn guide roll to realize three roller synchronous brake, pressure and stop rapid regression function; used to measure roll length and spindle combined gauge length; overfeed guide yarn and is directly driven by the motor, meet the loose type of the warping beam dyeing requirements; telescopic reed of the mobile electronic control equipment with intermittent suction cleaning device, the realization of the PLC control.The design of the whole machine is the trend of the intelligent development, the degree of the mechanical and electrical integration of the equipment is increasing. Warping and back transmission shaft are used AC frequency conversion technology, realize the warping of horizontal speed, constant tension winding; whole the starting position, the positioning can one button automatically; the whole table guide yarn device with yarn winding layer automatically along the radial back and realize distance winding; application of Fieldbus line, so that all the production equipment debugging, fault diagnosis and process parameter setting management is more intelligent.With the continuous development of modern high-speed looms, manufacturing equipment warping machine is put forward, which includes all the tension of moderate values of, the warp tension consistent and in warping process is kept constant, the warp arranged uniformly, normal whole warp beam winding shape, beam surface non convex and concave unevenness, warp beam winding density and proper uniform, warping root number, length, amplitude, yarn arranged in line with the specified in the design process, yarn breakage auto stop sensitive content, and higher requirements. Therefore, modern winding speed and beaming rolled mounted to the high speed and large volumes of direction at the same time must seriously consider the practical problems.At present, the whole machine winding speed, generally in 600 meters / minute ~1000 meters / minute, some of the maximum equipment can reach 1200 meters / minute. But this is only theoretical number, in the actual operation of the production, the short fiber is the whole winding speed of 450 meters / minute, chemical fiber filament winding speed in 800 meters / minute or so. The speed upgrade does not go up the main reason is too high the whole speed and warping of the warp tension and bobbin capacity tend to conflict. All the size and speed can directly affect to the tension of yarn during warping, under the same package diameter and tension weight, the whole winding speed and the tension of the yarn into proportional relationship. If you want to increase the speed of the winding, you must use the appropriate measures, otherwise can not get good winding effect. Yarn bobbin capacity is limited, in the case of collective doffing, winding speed warping is not too high.Improvement of the creel structure defect of warping machine Bottleneck Breakthrough DevelopmentBecause of the defects of domestic whole by the equipment in the beam form of pressure, adjustable reed, creel structure, resulting in the beam in tension, winding arrangement, three aspects can not fully meet the process requirements of the whole. Therefore, the use of science and technology for the transformation of the whole machine adopts the mechanical structure, it is very necessary to improve the domestic whole machine warp beam driving and creel, tension device.Whole the creel is an important part of the whole machine, with the whole the continuous improvement of winding speed, requirements for the creel is also more and more high. Creel not only to meet the whole process of the basic requirements, but also to minimize the whole of yarn tension in the process of change, improve the quality of the whole; try to reduce the heat exchanger tube downtime, improve the production efficiency of the whole. Spoolrack sense has formed the bottleneck of the development of warping machine. To meet the requirements of high-speed warping and high-quality yarn warping, need to solve the following problems: a yarn high adaptability, namely less warp breakage rate; the second is to solve the whole difference and tension, improve the uniformity of yarn tension; the third is improve the whole efficiency and reduce surround the bobbin frame on the auxiliary time.At present, some domestic enterprises have developed large "V" type creel, hundreds of bobbin unwinding cited yarn route with no tension plate, there is no guide yarn poteye and no angular yarn guiding, the friction is reduced to the minimum degree and is conducive to high speed yarn guide. But how to reduce the warp yarn tension difference, which is a very important point is required all clip yarn plate stop synchronization performance is good, the large "V" - type creel chain and transmission mechanism with high transmission accuracy, guarantee the positioning cylinder accurately; secondly broken yarn automatic stop monitoring device, an air blowing cleaning device sensitivity and efficiency, but also affect the whole tension uniformity are important factors. In short, creel involves a lot of problems appear to be small; however, it is difficult to solve the problem, it is necessary to do further research and discussion.Experts believe that modern spoolrack should adopt single creels and batch collective doffing
