Description
本发明属纺织行业的转杯纺纱领域。The invention belongs to the field of rotor spinning in the textile industry.
转杯纺纱通过给棉、分梳和转杯凝聚加捻形成纱线，经引纱和卷绕装置得到转杯纺筒子状卷装的纱线。作为转杯纺纱的一个条件，棉条经分梳辊和气流通道作用分离成截面内仅含1-4根纤维的连续纤维流后再进入转杯。这是转杯进行顺利纺纱的必要条件，也是约束提高转杯纺纱产量和扩展纺纱支数的关键条件。The rotor spinning is formed by kneading the cotton, the carding and the rotor to form a yarn, and the yarn of the rotor-spinning package is obtained by the yarn-feeding and winding device. As a condition of the rotor spinning, the sliver is separated into a continuous fiber flow having only 1-4 fibers in the cross section by the opening roller and the air flow passage, and then enters the rotor. This is a necessary condition for smooth spinning of the rotor, and is also a key condition for constraining the production of rotor spinning and expanding the number of spinning counts.
以此关键点为中心，为了提高转杯纺纱产量有两个途径：一个途径是提高分梳辊对棉条的牵伸倍数，保证喂入的棉条经分梳辊和气流的分离后形成截面纤维为1-4根的连续纤维流；第二个途径是提高转杯速度及引纱速度。本专利重点讨论通过提高分梳辊对棉条的牵伸倍数来提高转杯纺纱产量和扩展纺纱支数的专利技术。Focusing on this key point, there are two ways to increase the rotor spinning output: one way is to increase the drafting ratio of the opening roller to the sliver, and to ensure that the fed sliver is formed by the separation of the opening roller and the airflow. The cross-section fibers are 1-4 continuous fiber streams; the second is to increase the rotor speed and the take-up speed. This patent focuses on a patented technique for increasing rotor spinning yield and expanding spinning count by increasing the draw ratio of the carding roller to the sliver.
近几年，转杯速度已有了成倍地提高，而分梳辊的8000rpm的转速被认为是其极限转速，以过高的分梳辊转速剥取和分梳棉条，会造成纤维被折断或拉断，使得成纱强力急剧下降。在转杯前端，分梳辊及气流通道对棉条的分离度就是一个重要且需要控制的指标。In recent years, the speed of the rotor has been increased exponentially, and the speed of the 8000 rpm of the opening roller is considered to be its limit speed. Stripping and slivering at too high a speed of the opening roller will cause the fiber to be quilted. Breaking or breaking, the yarn strength drops sharply. At the front end of the rotor, the separation of the sliver by the opening roller and the air flow path is an important and important indicator of control.
假定棉条所含纤维根数为常数，且气流通道对纤维流的分离度是常量(通过两端气流压差控制)，则可用纤维流离开分梳辊时其截面纤维根数作为分梳辊对棉条的分离度。显然，纤维根数越少分梳分离度越高，纤维根数越多分梳分离度越低。转杯纺在成纱过程中分梳辊表面纤维的分离度必须达到一定程度，低于这个程度，就会出现堵分梳辊和堵转杯的情况，不论纺低支纱还是高支纱，对进入转杯的纤维流的分离度都是一样的，即连续纤维流截面内纤维根数为1-4根。Assume that the number of fibers contained in the sliver is constant, and the separation of the gas flow channel to the fiber flow is constant (controlled by the pressure difference between the two ends of the gas flow), and the number of fibers of the cross section of the fiber can be used as the opening roller. The degree of separation of the sliver. Obviously, the lower the number of fibers, the higher the degree of separation of the comb, and the more the number of fibers, the lower the comb separation. In the process of yarn spinning, the separation degree of the surface of the opening roller must be a certain degree. Below this level, there will be a situation of blocking the combing roller and the blocking cup, regardless of whether the low or high yarn is spun. The degree of separation of the fiber streams entering the rotor is the same, ie the number of fibers in the cross section of the continuous fiber stream is 1-4.
要提高纺纱产量，就必须提高棉条的供应量。假定棉条定量不变，则为了提高棉条供应量就必须提升给棉罗拉的转速。为了使棉条仍达到原有的纤维分离度，就必须按比例提升分梳辊的转速。但以过高的分梳辊转速剥取和分梳棉条，会造成过多的纤维被折断或拉断，使得成纱强力急剧下降。一般，分梳辊的最高速度是8000rpm。这就造成了分梳辊的分梳能力与转杯速度提升的不匹配。To increase the spinning output, it is necessary to increase the supply of sliver. Assuming that the sliver weight is constant, the speed of the feed to the cotton roller must be increased in order to increase the sliver supply. In order for the sliver to still reach the original fiber separation, the speed of the opening roller must be increased proportionally. However, stripping and slivering the sliver at an excessively high number of opening rollers causes excessive fibers to be broken or broken, resulting in a sharp drop in yarn strength. Generally, the maximum speed of the opening roller is 8000 rpm. This results in a mismatch between the carding ability of the opening roller and the increase in the speed of the rotor.
同样，在纺粗支纱时，以同样定量的棉条喂入，给棉罗拉速度要比高支纱棉
条喂入速度大很多，为了达到进入转杯时的纤维分离度，生产粗支纱比高支纱需要更大地分离度和更高地分梳辊转速。由于分梳辊的最高速度是8000rpm，在生产中低支纱时，分梳辊的最高转速限制了分梳纤维的供应量，故出现纺低支纱时产量高但纺纱速度不高的怪圈。Similarly, when spinning coarse yarns, feeding with the same amount of sliver, the speed of the cotton roller is higher than that of the high cotton yarn.
The feed rate of the strip is much higher. In order to achieve the fiber separation when entering the rotor, the production of the coarse yarn requires a greater degree of separation and a higher opening speed than the high count yarn. Since the maximum speed of the opening roller is 8000 rpm, the maximum rotation speed of the opening roller limits the supply of the carding fibers in the production of the medium and low-counting yarns, so that the yield is high but the spinning speed is not high when the low-yarn yarn is spun. .
总而言之，提升转杯纺纱机生产效率的主要矛盾是：高分梳辊转速与纤维损伤增大的矛盾。All in all, the main contradiction in improving the production efficiency of the rotor spinning machine is the contradiction between the high-spinning roller speed and the increase in fiber damage.
发明内容Summary of the invention
为了解决上述问题，本发明采用三级分梳转杯纺纱方法，包括给棉、分梳、凝聚加捻、引纱卷绕。分梳采用三级分梳辊，即第1分梳辊、第2分梳辊和第3分梳辊平行排列组成。三级分梳辊的转速逐级递增，第1分梳辊的转速为3000-5000rpm，第2分梳辊的转速为6000-10000rpm，第3分梳辊的转速为12000-20000rpm，三级分梳辊的梳针密度逐级增大，梳针工作角逐级减小。In order to solve the above problems, the present invention adopts a three-stage carding rotor spinning method, which comprises cotton feeding, carding, coagulation and twisting, and yarn winding. The carding is composed of a three-stage opening roller, that is, the first opening roller, the second opening roller and the third opening roller are arranged in parallel. The rotation speed of the three-stage opening roller is gradually increased, the rotation speed of the first opening roller is 3000-5000 rpm, the rotation speed of the second opening roller is 6000-10000 rpm, and the rotation speed of the third opening roller is 12000-20000 rpm, three-stage The needle density of the comb roller is increased step by step, and the working angle of the comb is gradually reduced.
在单分梳辊转杯纺中，分梳辊的作用包括两大部分，一个作用是从给棉罗拉与给棉板钳口的棉条中剥取纤维，实现纤维的分梳与分离，分梳辊速度的大幅度提升，使得分梳辊对纤维的剥取作用力增大，容易将纤维拉断，使成纱质量下降。另一个作用是将纤维运送到梳棉通道，分梳辊的转速越高，纤维的离心力越大，纤维更容易与分梳辊分离并进入梳棉通道。由于需要平衡剥取、梳理纤维，以及转移到梳棉通道时对纤维速度的要求，单分梳辊转速的最大值是受到限制的，一般认为不宜超过8000rpm。In the single-bath roll rotor spinning, the function of the opening roller comprises two parts, one function is to strip the fibers from the sliver of the cotton roller and the cotton plate to realize the carding and separation of the fibers. The large increase in the speed of the combing roller makes the stripping roller increase the stripping force of the fiber, and the fiber is easily broken, so that the quality of the yarn is lowered. Another function is to transport the fibers to the carding passage. The higher the rotational speed of the opening roller, the greater the centrifugal force of the fibers, and the fibers are more easily separated from the opening roller and into the carding passage. Due to the need for balanced stripping, carding, and fiber speed requirements when transferring to the carding passage, the maximum number of single-bath rolls is limited and is generally considered to be less than 8000 rpm.
而采用三级分梳辊，一方面通过逐级递增的牵伸比实现对棉条的柔性剥取和柔性牵伸；另一方面通过增大分梳系统的总牵伸比，实现分梳能力与转杯纺纱能力的匹配，提升转杯纺纱的适应性和进一步提高转杯纺纱产量。The three-stage opening roller is used to realize the flexible stripping and flexible drawing of the sliver by increasing the drawing ratio step by step; on the other hand, by increasing the total draft ratio of the carding system, the combing ability and The matching of rotor spinning ability enhances the adaptability of rotor spinning and further increases the rotor spinning output.
第一分梳辊的转速较低，这样可以保证分梳辊从给棉罗拉与给棉板钳口剥取纤维时，纤维所受的剥取拉力较小，减少纤维的断裂和损伤；第二分梳辊的转速高于第一分梳辊，经过第二分梳辊的梳理，纤维的纵向取向得到优化，横向转移混合进一步优化，纤维的分离度进一步提高；第三分梳辊是高速分梳辊，纤维经过第三分梳辊不仅得到更好的梳理与转移，此时，纤维基本处于单纤维状态，达到较高的纤维分离度，并且速度得到提升，到达进入梳棉通道的离心力要求，可以顺利有序的进入转杯成纱。同时三个分梳辊之间的速比较小，且分梳辊上纤维
之间的联系较弱，纤维在三个分梳辊之间的传递有离心力和气流的作用，纤维承受的剥取作用力很小，对纤维的损伤很小。The rotation speed of the first opening roller is low, so as to ensure that the stripping roller receives less fibers from the jaws of the cotton roller and the cotton sheet, the stripping force of the fibers is less, and the fiber breakage and damage are reduced; The rotation speed of the opening roller is higher than that of the first opening roller. After the combing of the second opening roller, the longitudinal orientation of the fiber is optimized, the lateral transfer mixing is further optimized, and the separation degree of the fiber is further improved; the third opening roller is a high speed The combing roller and the fiber through the third opening roller not only get better combing and transfer, at this time, the fiber is basically in a single fiber state, achieving a higher fiber separation degree, and the speed is improved, and the centrifugal force requirement for entering the carding passage is reached. , can smoothly and orderly enter the rotor into yarn. At the same time, the speed between the three opening rollers is relatively small, and the fibers on the opening roller
The relationship between the fibers is weak, and the transmission of the fibers between the three opening rollers has the effect of centrifugal force and air flow. The stripping force of the fibers is small and the damage to the fibers is small.
