Description

Two-for-one twist forming integrated spindle device

Technical Field

The utility model belongs to the technical field of spinning, and particularly relates to a two-for-one twisting and forming integrated spindle device.

Background

The spinning is a process of orderly arranging random loose fibers, sequentially opening, carding, drafting and the like, then linearly converging or directly twisting natural yarns, artificial yarns, chemical fiber yarns and the like. The twisting modes are different, and the structure, the efficiency and the like of yarns produced by spinning are directly determined. In general, twist spinning forms are classified into two types of grip end twisting and free end twisting. The holding end twisting can control the fiber strand to carry out forced cohesion twisting, and has the advantages of high cohesion force among fibers, high resultant yarn strength, good wear resistance and the like, such as a large number of wide ring spinning technology ring twisting forms. However, the ring spinning speed is low, generally tens meters per minute, and the main reason is that the twisting and winding mechanisms of the ring spinning are the same mechanism, the twisting and winding are simultaneously carried out, the twisting efficiency and the winding efficiency are mutually restricted, in addition, the spinning package of the spinning frame is formed into a conical cross winding form with a step-up, and the size of a spinning balloon is always changed and the spinning tension is changed when the large, medium and small yarns of the cop are formed in the whole spinning process, so that the quality difference of the produced large, medium and small yarns is larger. In general, the middle yarn spinning air ring of spun yarn cop is moderate, the resultant yarn quality is higher, the tension of spun yarn spun by small yarn is maximum, the resultant yarn quality is lowest, and the large yarn quality is centered. In order to improve the quality of ring spun yarns, novel ring spinning technologies such as compact spinning, siro spinning and soft and clean spinning are developed; however, these new spinning technologies are all in the form of ring-spun packages, and the problem of yarn quality differences caused by the packages has not yet been eliminated and solved. In order to improve spinning efficiency, open-end spinning techniques, such as rotor spinning speeds up to 280 m/min, are currently commonly used in factories; friction spinning speeds up to 500 m/min; vortex spinning speeds are up to 500 m/min. However, in open-end spinning, the fibers in the twisted fiber strands cannot be effectively and sufficiently cohesive due to the fact that the fiber strands cannot be effectively held by twisting, so that the resultant yarn has low strength and poor wear resistance.

In order to improve the twisting efficiency of spun yarn, reduce twisting energy consumption, increase spun yarn package, realize the production of ultra-long large package spun yarn, chinese patent publication No. CN109554784A, publication No. 2019.04.02, the invention creates a double-twist spinning frame, the invention provides a double-twist twisting winding mechanism of the ring spinning frame, the double-twist mechanism and the drafting mechanism are separately arranged, the twisting mechanism is simply and conveniently realized to rotate for one circle, the high-efficiency twisting effect of applying 2 twists to the sliver is achieved, and the technical problems of poor practicality and low application popularization value of the technical device are solved because of the fact that a double-twist spinning device (Chinese patent publication No. CN103820889A, publication No. 2014.05.28) with the drafting mechanism and the roving hanging mechanism is additionally arranged in a yarn storage tank on a static spindle of the double-twist mechanism is in the practical application process, the roving package is long, the drafting system is complex, and the mechanism is difficult to operate and spinning air ring greatly influences the quality of finished yarn; however, the two-for-one twisting spinning machine adopts the mode of sliding contact of the electric brush, the winding device in the yarn storage tank is connected with an external power supply to continuously operate and wind yarns, and the winding two-for-one twisting spinning mode of a built-in electric power mechanism is basically adopted, so that the sliding contact of the electric brush mechanism is quickly worn out, the service period is short, particularly, the higher the spinning speed is, the shorter the damage period of the electric brush conducting part device is, the damage is caused within even 2 hours, and the spinning winding cannot be continuously carried out, so that the two-for-one twisting spinning technology is directly restricted from being incapable of being permanently applied and widely popularized. Meanwhile, the current two-for-one spinning machine adopts a heavy hammer pressurizing mode for the bobbin package, so that the whole spinning device has large wool weight and large rotation load, and the yarn package weight and package size are limited. Therefore, the two-for-one twisting spinning machine not only has the technical bottleneck that a winding mechanism cannot operate at high speed and for a long time, but also has the limitation of large package winding spinning, so that the two-for-one twisting spinning machine cannot solve the problem of long-time spinning of high-speed large packages, only can adopt roving as a raw material to twist into yarns by low-power drafting, and cannot realize the ideal two-for-one twisting spinning production of high-drafting, high-speed and large package by cotton sliver directly.

In order to solve the technical problem that a built-in winding mechanism cannot operate at a high speed for two-for-one twisting spinning, chinese patent publication No. CN112410944A, publication No. 2021.02.26, the invention provides a magnetic winding type high-speed two-for-one twisting spinning machine, and provides a magnetic tensioner device which is used for changing a roving hanging mechanism of the existing two-for-one twisting spinning machine into a fiber thick strip feeding structure, changing a roving drafting mechanism into a fiber thick strip drafting mechanism, removing an original electric transmission mechanism arranged in a yarn storage tank, changing the existing two-for-one twisting winding mechanism into a two-for-one twisting magnetic winding mechanism, respectively embedding permanent magnets uniformly distributed along the circumferential direction on the outer end surfaces of a driving turntable of an external motor of the magnetic winding mechanism and a driven turntable of a winding groove drum, removing heavy weights in the original two-for-one twisting winding mechanism, and arranging a magnetic tensioner device between the outer side of a pipe sleeve and the inner wall of the yarn storage tank, thereby reducing the operating load of the device and solving a series of technical problems that the original two-for-one twisting spinning machine is poor in operation durability, low in efficiency, high in energy consumption, and cannot adopt a fiber thick strip to carry out high-power drafting and direct spinning.

The existing two-for-one twisting spinning device can not freely adjust the shape and tightness of the finished product rolled yarn after the winding forming, such as different shapes and tightness of edges, no edges, a tight cylinder, a loose cylinder and the like; if the tight cylinder can be directly used for the following procedures of shaping, sewing, braiding and the like; the pine cone can be directly used for dyeing and the like. Therefore, the secondary winding and forming are usually carried out on the finished winding yarn by using extra winding equipment according to actual conditions, so that the cost is high and the efficiency is low.

In order to omit a winding process, the Chinese patent publication No. CN1600913A, publication No. 2005.03.30, the invention provides a self-winding two-for-one twisting spindle, which comprises a fixed seat, a hollow spindle rod and a yarn placing frame, wherein a belt pulley is arranged on the hollow spindle rod, a yarn guide tube is fixed on the hollow spindle rod between the yarn placing frame and the fixed seat, a first magnet is fixed on the yarn placing frame, a second magnet is fixed on the fixed seat close to the first magnet, a rotating frame is rotatably arranged at the upper part of the hollow spindle rod, and a yarn guide hook is arranged on the rotating frame. A winding process can be omitted, and the spinning speed can be improved. In addition, the utility model has the functions of spinning fancy yarn and twisting ply.

In the above patent, the hollow spindle rod drives the bidirectional screw rod to rotate so that the sliding block moves up and down along the bidirectional screw rod, and the displacement speed of the sliding block is determined by the rotating speed of the hollow spindle rod, so that the shape and the tightness of the finished product winding yarn after winding and forming cannot be freely adjusted; meanwhile, when the hollow spindle rod rotates, the hollow spindle rod drives the rotating frame to synchronously or asynchronously rotate with the hollow spindle rod through friction force, when twisted yarns are wound on the bobbins through the guide hooks, the yarns generate winding tension, under the action of the tension, the rotating speed of the rotating frame is slower than that of the hollow spindle rod, the driving belt pulley and the driven belt pulley rotate, the sliding block moves up and down along the bidirectional screw rod in a reciprocating manner, and meanwhile the bobbins rotate to finish winding forming of the yarns.
