Description
Technical Field
The invention relates to a magnetic drive type twisting device controlled by a single spindle and application thereof, belonging to the technical field of textiles.
Technical Field
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 and control the fiber strands 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 a ring twisting form of a ring spinning technology with large quantity and wide range. The ring twisting mechanism consists of a spindle, a steel collar and a steel wire ring; in the twisting process, the spindle is driven by the spindle belt to rotate at a high speed of 18000 rpm to drive the bobbin inserted on the spindle to wind a sliver, the sliver drags the steel wire ring bestriding the steel collar to move at a high speed (about 40 m/s) along the circular ring-shaped track of the steel collar, the friction ratio is higher, the steel wire ring is easy to damage and short in service life, and the spinning efficiency and the yarn quality are severely restricted. Meanwhile, the spindle runs at a high speed, the slipping between the belt and the spindle is easy to occur, the friction force between the spindle foot and the spindle seat of the spindle is large, the abrasion is high, and the lubricating oil agent needs to be frequently replaced, so that the power utilization rate of spinning and twisting is low, the loss of special equipment parts is large, and the maintenance and running cost is high. Meanwhile, the mechanical twisting mechanism comprises twisting keel, spindle belts, mounting supports, spindle seats and other parts, the spindle speeds of all spindles of one trolley are driven by the same twisting keel, the spindle speeds are kept consistent, single-spindle control and differential individual production operation among spindles cannot be carried out, and the production requirements of small-batch and various yarns of the existing spinning enterprises cannot be met.
In order to solve the technical problems that ring twisting parts are easy to wear, high in energy consumption and multiple in components, the invention provides an electromagnetic suspension spindle and an electromagnetic device in China patent publication No. CN1052342A, published Japanese 1991.06.19, the application public case provides a high-speed self-stabilizing spindle which generates magnetic suspension force through electromagnetic effect to replace an oil suspension spindle, the electromagnetic suspension spindle provided by the application public case consists of a magnetic pole ring spindle blade and a current ring bearing seat, and the existing production process and equipment are not required to be changed, so that the spindle generates electromagnetic effect when rotating at high speed (the speed is higher than 6000 revolutions per minute), and the purpose of magnetic suspension rotation is achieved. Therefore, the power source for rotating the spindle of the application publication still adopts belt transmission, and the purpose of magnetic suspension rotation of the spindle cannot be realized at low speed (the speed is lower than 6000 rpm). In order to solve the problem of high-speed operation of the rotor spinning twisting rotor, Chinese patent publication No. CN101617136B, published Japanese 2013.02.06, the invention provides a method for suspending, centering, stabilizing and driving electromagnetic functional components of a warp-wise electromagnetic bearing and an electric rotary driving device, an electromagnetic bearing and driving system and a spinning mechanism of a rotor spinning machine, the application publication provides a method for suspending, centering, stabilizing and driving single electromagnetic functional components of the warp-wise electromagnetic bearing and the electric rotary driving device, and the electric rotary driving device can move and rotate in a stator of a radial electromagnetic bearing through the action of a magnetic flux component; the steady magnetic flux and the driving magnetic flux from the separate magnetic flux sources simultaneously act on electromagnetic functional parts of the radial electromagnetic bearing and the electric rotary drive that are common to the radial electromagnetic bearing and the electric rotary drive; while the application publication proposes that the electromagnetic functional part is applied exclusively for driving a spinning rotor on a rotor spinning machine, which spinning rotor is mounted in a coaxial manner in the space between a radial electromagnetic bearing spindle and an electric rotary drive stator, the spinning rotor being a rotary body with a closed bottom, the yarn nozzle being positioned in the hole formed in the stator of the electric rotary drive. Although the application publication also adopts the magnetic technology to solve the technical problem of rotor high-speed driving of rotor spinning, the device has complex mechanism, the magnetic flux of electromagnetic induction needs to be precisely controlled to drive the rotor of rotor spinning to move, the purchase and running cost of an electromagnetic bearing is higher, and particularly, the power generated by electromagnetism is only limited to the rotation of a rotor spinning low-strength ultrahigh-speed rotor false twisting disc and cannot meet the rotation of large power such as a ring twisting spindle and a double twisting spindle. Therefore, the problems of low abrasion, high speed, easy care, independent operation and single spindle control of ring twisting and double twisting spindles are not solved by the prior art at present.

When the two-for-one twister twists yarns, the single spindle driving motor 13 is externally connected with a power supply and has a speed regulation function, a controller with functions of displaying the spindle speed and the number of spun yarns in real time, starting and closing and the like is used for starting the single spindle driving motor 13, the single spindle driving motor 13 drives the magnetic rotating disc 11 to rotate anticlockwise at the speed of 1000 revolutions per minute, the ratio of the diameter of the magnetic rotating shaft to the inner diameter of the magnetic rotating disc 11 is 1/6, the magnetic rotating disc drives the magnetic rotating shaft through magnetic force, so that the magnetic suspension rotor 1 and the connecting bolt 4 perform magnetic suspension type high-speed abrasion-free rotation at the speed of 6000 revolutions per minute, and the two-for-one twister spindle rod of the two-for-two twister substantially obtains the rotating speed of 6000 revolutions per minute and drives the twisting disc 32 and the spindle disc to. 3-ply doubling of 120 Nm single yarn count and 340 single yarn twist factor is unwound from a cylindrical doubling package 28 placed in a yarn storage tank 30, introduced into a hollow shaft through a flyer 29, uniformly tensioned by a tensioner in a connecting sleeve 27 of a tension tube, and then introduced into a yarn feeding duct. Under the combined action of the inner magnetic steel and the fixed magnetic steel arranged on the two-for-one twisting machine, the yarn storage tank 30 and the static disc keep static; the combined yarn in the yarn inlet channel is firstly twisted in a plying way in the S-twist direction by the twisting disc 32 and the spindle disc which rotate at the speed of 6000 revolutions per minute, the folded yarn after the first plying and twisting enters the yarn outlet pipeline 31, the yarn output from the yarn outlet pipeline 20 passes through the yarn guide hook 20 and the grooved drum 26 in sequence, and is finally wound on the bobbin 25 at the speed of 20 meters per minute, the folded yarn between the yarn outlet pipeline 31 and the yarn guide hook 20 is twisted for the second time in the S-twist direction, the twisted yarn degree of the folded and twisted folded yarn is 60 twists per 10 centimeters, and the twist direction is the S-twist. Through 24-hour continuous operation comparison tests, compared with the twisting production of a conventional belt-driven two-for-one twister, the invention operates the spinning at a high rotating speed of 6000 revolutions per minute, the operation noise is reduced by 32 percent, the daily output energy consumption is reduced by 6.3 percent, no wear mark is found on the outer surfaces of the two-for-one twisting spindle rod, the magnetic suspension rotor 1, the magnetic base 19 and the driving device, and the operation of the low-wear, noiseless and oilless lubricant type magnetic drive twisting mechanism is realized. The magnetic driving twisting device controlled by the single spindle is applied to the two-for-one twister, and replaces twisting mechanisms which are complex in structure, large in running abrasion and low in transmission efficiency, such as two-for-one twisting keel, two-for-one twisting belt, two-for-one twisting spindle seat, two-for-one twisting spindle frame and two-for-one twisting belt pulley and the like on the original two-for-one twister, so that the problems existing in the twisting of the existing two-for-one twisting spindle are solved, and the double-twister which is low in abrasion, high in speed, easy to care, capable of running independently and controlled.
