Description
Technical Field
The invention relates to a double-twist spinning machine, in particular to a magnetic winding type high-speed double-twist spinning machine, and belongs to the technical field of spinning.
Background
The spinning is a process of orderly arranging disordered loose fibers in the processes of opening, carding, drafting and the like, and then linearly converging and twisting. The twisting mode is different, and the structure, the efficiency and the like of the yarn produced by spinning are directly determined. In general, the twist spinning forms are classified into grip end twisting and free end twisting. The gripping end twisting can limit control the fiber strand to carry out forced cohesion twisting, and has the advantages of large cohesion force between fibers, high yarn forming strength, good wear resistance and the like, such as ring spinning technical ring twisting form with large quantity and wide range. However, the speed of ring spinning is low, generally tens of meters per minute, the main reason is that the ring spinning twisting and winding mechanism is the same mechanism, twisting and winding are carried out simultaneously, the twisting efficiency and the package efficiency are mutually restricted, in addition, the spinning package of the spinning frame is formed into a conical cross winding form with grade rise, in the whole spinning process, when the large, medium and small yarns of the cop are formed, the size of the spinning balloon is always changed, the spinning tension is changed along with the change of the spinning balloon, and therefore, the quality difference of the produced large, medium and small yarns is large. In general, the middle yarn spinning balloon of the spun yarn bobbin is moderate, the quality of the finished yarn is high, the tension of the spun yarn is the largest, the quality of the finished yarn is the lowest, and the quality of the spun yarn is medium. In order to improve the quality of ring spun yarns, novel ring spinning technologies such as compact spinning, siro spinning, soft and clean spinning and the like are developed; however, these new spinning techniques are all in the form of ring spinning packages, and the problem of the package form causing yarn quality difference is still not eliminated or solved. In order to improve the spinning efficiency, the current factory usually adopts the open-end spinning technology, such as the rotor spinning speed is up to 280 m/min; the friction spinning speed is up to 500 m/min; vortex spinning speeds are up to 500 m/min. However, when spinning at the free end, because the twisting of the fiber strands can not be effectively held, the fibers in the twisted strands can not be effectively and fully cohered, the strength of the resultant yarn is low, and the abrasion resistance of the yarn is poor. Therefore, the technical problem of contradiction between high quality of the twisted yarn and high-speed large package is generated at present.
In order to improve the spinning yarn twisting efficiency, reduce the twisting energy consumption, increase the spinning yarn package and realize the production of ultra-long large package spun yarns, the Chinese patent publication No. CN109554784A, the publication No. 2019.04.02, the invention provides a double-twist spinning frame, the application publication provides a double-twist twisting winding mechanism which is changed from a ring spindle twisting winding mechanism of a ring spinning frame, the double-twist mechanism and a drafting mechanism are separately arranged, the twisting mechanism rotates for a circle simply and conveniently, and the high-efficiency twisting effect of 2 twists is exerted on the yarn, thereby solving the problem that the double-twist spinning device (the Chinese patent publication No. CN103820889A, the publication No. 2014.05.28) which is additionally provided with the drafting mechanism and the roving hanging mechanism in a yarn storage tank on a static spindle of the double-twist mechanism has poor practicability due to the long spinning package, the complex drafting system, the difficult mechanism operation during the spinning, and the large influence on the yarn quality due to a spinning balloon, and the technical device has poor practicability, Low application and popularization value; however, the two-for-one twisting spinning machine of the invention adopts a mode of sliding contact of the electric brush to connect the winding device in the yarn storage tank with an external power supply to continuously operate and wind the yarn, and the winding type two-for-one twisting spinning mode of the built-in electric mechanism is substantially adopted, so that the sliding contact electric brush mechanism is rapidly worn and has short service cycle, and particularly, the higher the spinning speed is, the shorter the damage cycle of the device at the electric brush conducting part is, even the device is damaged within 2 hours, and the continuous spinning winding can not be carried out, thereby directly restricting the durable application and wide popularization of the two-for-one twisting spinning technology. Meanwhile, the bobbin package in the existing two-for-one twisting spinning machine adopts a heavy hammer pressurization mode, so that the whole spinning device is heavy in weight and large in rotation load, and the yarn package weight and package size are limited. Therefore, the two-for-one twisting type spinning machine has the technical bottleneck that a winding mechanism cannot run at a high speed for a long time, and the large-package winding spinning is limited, so that the existing two-for-one twisting spinning machine cannot solve the problem of the long-lasting spinning of a high-speed large package, only can adopt rough yarns as raw materials to carry out low-power drafting and twisting to form yarns, and cannot realize the ideal two-for-one twisting spinning production of large drafting, high-speed and large roll by adopting cotton slivers directly.

During spinning, the driving turntable 7 of the external motor 8 of the magnetic winding mechanism drives the driven turntable 24 of the winding groove drum 16 to rotate under the action of magnetic force, the driving turntable 7 of the external motor 8 is adopted, and the driven turntable 24 connected with the magnetic force drives the winding mechanism of the winding groove drum 16 to rotate, so that an electric transmission mechanism arranged in a double-twist winding structure is removed, the technical problems that an electric brush mechanism in sliding contact is rapidly worn and the service cycle is short due to the adoption of a winding type double-twist spinning mode of an internal electric mechanism are solved, the technical bottleneck that the internal electric winding mechanism of the double-twist spinning cannot operate at a high speed durably is broken, the durability of double-twist high-speed spinning and the durability of parts are greatly prolonged, and the high-efficiency double-twist high-speed spinning production of a spinning frame and the durable twisting high-speed spinning production of a high-capacity yarn package are practically achieved; the spindle belt 12 of the double twisting mechanism drives the twisting disc 11 on the spindle rod 15 to rotate at the speed of n revolutions per minute, fiber rough yarn unwound from the sliver can 1 is guided by the rear rod and the front rod of the sliver guide framework, and sequentially enters a sliver bell mouth of the fiber rough sliver drafting mechanism, a rear rubber roller and a rear roller which are engaged to form a rear roller jaw, a middle rear roller jaw formed by engaging a middle rear upper roller and a middle rear lower roller, a middle front leather collar jaw formed by engaging a middle front upper roller, a middle front upper leather collar, a middle front lower roller and a middle front lower leather collar, a front rubber roller 2 and a front roller jaw formed by engaging a front roller 3, the total drafting multiple is 90-160, the rollers output at the linear speed of 50-280 meters per minute to form fiber strands, the fiber strands form strands under the twisting action of the twisting disc 11, and the strands pass through the guide hook 4, the yarn feeding pipe 27 of the twisting disc 11, the yarn feeding channel in the rotor combining part 28, the yarn discharging pipe in the positioning sleeve 6 and the tensioner 29 running into the yarn discharging pipe are sequentially arranged, the twisting disc 11 respectively applies n twists in the same twisting direction to the yarns running in the sections from the front roller jaw and the yarn feeding pipe 27, the yarn feeding pipe 27 and the tensioner 29 every minute, the twisting disc 11 applies 2n twists to the yarns running in the sections from the front roller jaw to the tensioner 29 every minute, and 2-fold twisting spinning is carried out, so that the low-efficiency twisting mode that only one twist can be added to a steel wire ring of a common ring spinning frame in one rotation is changed, and the twisting efficiency of the common spinning frame is greatly improved; the 2-by-one twisted yarn is drawn out from the yarn outlet duct by the tension device 29, and then wound on the bobbin 17 by the winding action of the winding grooved drum 16 which is rotated, to form a package of a yarn package. The high-efficiency twisting and the high-speed winding can be effectively cooperated, so that the technical problem that the contradiction technical bottleneck that the two-for-one twisting spinning technology cannot simultaneously realize the high-speed twisting and the high-speed winding is solved, and the technical problem that the two-for-one twisting spinning can be used for carrying out lasting and high-speed cone yarn package is solved. The double-twist spinning method of the original built-in electric mechanism winding is adopted to produce a pure cotton 14.8-tex product with the twist of 110 twist/10 cm, 5.4 g/10 m thick yarn is subjected to low-power drafting and then is conveyed at the linear speed of 12 m/min through a front roller jaw, the twisting speed of the double-twist mechanism is 6600 r/min, the winding mechanism finishes 5 ten-thousand-meter package of yarn, the machine is stopped for 2 times due to the abrasion of an electric brush, the output linear speed and the twisting speed of the front roller yarn strip are further increased, and the abrasion period of the built-in electric mechanism is shorter; the method of the invention is adopted for production, 14.8-tex pure cotton yarn with twist of 110 twist/10 cm is produced in the same way, 3.5 g/m thick yarn is adopted for high-power drafting, the roving is conveyed at the linear speed of 60 m/min through a front roller jaw, the twisting speed of a double-twist mechanism is 33000 r/min (a double-twist shaft adopts a magnetic suspension high-speed bearing), the winding mechanism successfully finishes 10 5-ten-thousand-meter bobbin yarn packages, the stopping and end breakage conditions caused by the failure of the winding mechanism do not occur, the yarn hairiness amount is greatly increased (the amplitude is 2.5 times) due to the high double-twist speed and the large air ring tension, but the excessive yarn hairiness problem can be solved through the subsequent singeing and sizing procedures; because the built-in electric power mechanism is cancelled, the driven turntable 24 is arranged in a frame shape or a hollow shape, the heavy hammer pressurizing mechanism with larger original weight is replaced by the portable magnetic tensioner device, the running load of winding and double-twisting is greatly reduced, and compared with the spinning of the winding mechanism of the original built-in electric power mechanism, the energy consumption is reduced by 15.3 percent, thereby being capable of carrying out high-speed double-twisting and winding, and the high-speed double-twisting and winding correspond to high-power drafting, thereby realizing the high-power drafting spinning of fiber thick strips; therefore, the invention really realizes the durable, stable and high-speed two-for-one twisting and winding production of the holding end spinning.
