Description

Technical Field

[0001] The invention relates to the technical field of twist spinning, in particular to a synchronous twist spinning device and a spinning method for textile production. Background Art

[0002] The synchronous twisting spinning device is used for twisting different fibers such as polyester, nylon, polypropylene, aramid, grass silk, etc. It is suitable for various twisting methods such as single filament, multi-ply, double twist, etc. Twisting process: In the twisting machine, the fiber passes through a series of rollers and clamping devices; the fiber is stretched and twisted at the same time; friction is generated between the fibers, so that the fibers are more closely combined; at the same time, the stretching of the fiber can also change the molecular structure of the fiber, and improve the strength and elasticity of the fiber.

[0003] Necessary conditions for twisting: Twisting uses the bending and twisting of fibers. Bending can cause winding, and twisting can form twist. If one end of a fiber strip is fixed and the other end is twisted, there is a certain tension, which will produce twist. If there is no tension, the twisting of the fiber may be converted into bending, and the fiber strip will be twisted into a small braid. Therefore, tension and twisting are necessary conditions for twisting.

[0004] Announcement No. CN109763222A discloses a synchronous counter-twisting spinning device, which relates to the field of spinning. The synchronous counter-twisting spinning device comprises a base, the upper surface of the base comprises a chute, a slide bar, a slider, an alarm mechanism, a first support plate, a second support plate, a fixing mechanism, a driving mechanism, a twisting device and a control panel, the chute is opened on the right side of the upper surface of the base, the left and right sides of the slide bar are fixedly connected to the inner wall of the chute, the surface of the slide bar is slidably connected to the inner wall of the slider, the surface of the slider is slidably connected to the inner wall of the chute, and the upper surface of the slider and the upper surface of the base are fixedly connected to the bottom of the alarm mechanism. The synchronous counter-twisting spinning device, when monitoring the change in the distance between the first fixed block and the second fixed block, controls the twisting device to be closed through a controller, so that the twisting device is closed in time after the material is stuck, to prevent the accumulation of a lot of yarn in the twisting device, which is more troublesome to maintain.

[0005] When the fiber strips are twisted, they are pulled by the pulling structure, and the resulting fiber strips will have differences in uniformity and strength. During the twisting process, the positions with lower fiber content will not have sufficient strength, which will cause the fiber strips to break during the twisting process, affecting the final yarn quality. Summary of the invention

[0006] One of the purposes of the present invention is to provide a synchronous twisting spinning device and spinning method for textile production, which changes the twisting intensity of the fiber strips by monitoring the content state of the fiber strips, ensures the stability of the fiber strips during the twisting process, and avoids the situation where the fiber content of the fiber strips does not match the twisting strength.

[0048] 4. The twisting length of the fiber strips can be adjusted through the control component to ensure the accuracy of the fiber strips during the twisting process. Automatic adjustments can be made according to the state of the fiber strips to ensure that the twisting length of the fiber strips is consistent with the fiber strip content. By controlling multiple fiber strips, each fiber strip can be controlled individually to ensure the spinning quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. And if it is possible to implement, the features of different embodiments can be applied interchangeably.

[0068] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which can be understood by those familiar with this field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the content of this specification as consistent with the meanings of the relevant fields of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal meanings.

[0069] See also Figure 1-Figure 14 The present invention provides a synchronous twisting spinning device and a spinning method for textile production, which adjust the twisting state according to different fiber strip contents to ensure stability during the twisting process.

[0070] In one embodiment, the twist spinning device comprises:

[0071] The machine body 100 has a feed inlet 200 at the bottom thereof, and the fiber strips enter through the feed inlet 200;

[0072] The detection component 300 is arranged in the moving path of the fiber strip, changes the position of the fiber strip by static electricity, and obtains the internal content of the fiber strip according to the position change of the fiber strip;

[0073] The twisting assembly 400 is located on the upper part of the detection assembly 300. The fiber strips that have been tested for content are twisted by the twisting assembly 400, and the twisting length of the fiber strips by the twisting assembly 400 is changed according to the content of the fiber strips. When the content inside the fiber strips is greater than the normal content, the twisting length of the fiber strips is lengthened, and when the content inside the fiber strips is less than the normal content, the twisting length of the fiber strips is shortened.

[0074] The twisting structure 500 can be rotatably installed inside the machine body 100, and the fiber strips twisted by the plurality of twisting components 400 enter the outside of the twisting structure 500 for twisting and combining.

[0075] In this embodiment, the detection component 300 changes the state of the fiber strip through static electricity. Since the different contents of the fiber strip will produce changes in weight, when the detection component 300 generates static electricity, it affects the fiber strip and can move the fiber strip to different positions. The changes in different positions reflect the content of the fiber strip.

[0076] However, when the twisting component 400 performs twisting with the same intensity, the fiber strips with less fiber content may break, and the fiber strips with more fiber content may not be twisted with enough intensity, resulting in substandard twisting quality.

[0077] Among them, when twisting, the twisting component 400 changes the twisting length of the corresponding fiber strip according to the content of the fiber strip, so that the twisting strength of the fiber strip is the same as the content of the fiber strip.

[0078] In one embodiment, the torsion structure 500 includes:

[0079] The driving motor 501 is fixed inside the machine body 100. A positioning plate 502 is arranged outside the output end of the driving motor 501. The positioning plate 502 can be detachably installed inside the output end of the driving motor 501 to support the twisted fiber strips and change the tension of the fiber strips during the twisting process by cooperating with the twisting assembly 400.

[0080] The groove 503 is provided on the outside of the driving motor 501 , and the fiber strip enters the groove 503 after being twisted.

[0081] Optionally, the positioning plate 502, driven by the driving motor 501, will change the position state of the positioning plate 502, thereby being able to support the fiber strip. Under the support of the positioning plate 502, the fiber strip will change its position on the outer side of the positioning plate 502. After the position on the outer side of the fiber strip changes, the tension changes.

[0082] Alternatively, the positioning disk 502 and the driving motor 501 are eccentrically driven, the positioning disk 502 is an eccentric wheel, and the driving motor 501 drives the positioning disk 502 to change its position so as to support changes in fiber strips at different positions.

[0083] In one embodiment, a connection structure is provided between the driving motor 501 and the positioning plate 502:

[0084] The positioning frame 504 is arranged between the output shaft of the driving motor 501 and the positioning plate 502. A magnetic member 507 is arranged inside the positioning frame 504. A top block 505 for supporting the fiber strip is arranged inside the groove 503. A displacement sensor 506 is arranged outside the top block 505 to detect the displacement parameters of the top block 505.

[0085] The control of the groove 503 by the magnetic member 507 is divided into two stages. The displacement sensor 506 detects the position of the top block 505. The top block 505 shrinks under the force of the fiber strip, and the magnetic member 507 changes the magnetic control position of the top block 505 to support the fiber strip.

[0086] In this embodiment, the side of the top block 505 close to the magnetic part 507 is magnetically set, wherein the magnetic part 507 is an electromagnet, an electromagnetic ring or any other component that can change the magnetic force. The magnetic part 507 controls the position change of the top block 505, and the top block 505 can continuously change the tension of the fiber strip after changing its position.

[0087] Among them, under the support of the top block 505, the strength of fiber strips with the same content after twisting is almost the same, so the force acting on the top block 505 is also not much different. When the force acting on the top block 505 by the fiber strip changes, it means that the strength of the fiber strip changes. Therefore, the displacement parameters of the top block 505 are obtained through the displacement sensor 506, and the position of the top block 505 is adjusted according to the displacement parameters.

[0088] In one embodiment, the detection component 300 includes:

[0089] The electrostatic generator 301 is fixed inside the machine body 100. The electrostatic generator 301 generates static electricity. A guide plate 302 is arranged on one side of the electrostatic generator 301. An adjustment structure is arranged on the outer side of the guide plate 302 to adjust the position of the guide plate 302. One end of the feed port 200 extends between the electrostatic generator 301 and the guide plate 302.

[0090] The detection unit 303 is installed inside the machine body 100 to obtain the position of the fiber strip between the electrostatic generator 301 and the guide plate 302 and the moving speed thereof.

[0091] Optionally, the detection unit 303 is an ultrasonic detection unit. During use, the offset position of the fiber strip and the movement speed of the fiber strip are obtained through ultrasound, and the time of the twisting position of the fiber strip is calculated based on the offset position of the fiber strip and its movement speed.

[0092] Alternatively, the detection unit 303 is an image acquisition system, which acquires the offset position image of the fiber strip to obtain the offset position of the fiber strip, thereby analyzing the fiber content inside the fiber strip, and acquiring the feeding speed of the fiber strip to calculate the moving position of the fiber strip.

[0093] In this embodiment, the moving position of the fiber strip is calculated according to the moving speed of the fiber strip, so that the precise moving position of the fiber strip can be obtained, wherein the detection component 300 can be set to a vertical position or a horizontal position.

[0094] In one embodiment, adjusting the structure includes:

[0095] The moving frame 304 is disposed on the upper and lower sides of the guide plate 302 and is used to limit the position of the guide plate 302;

[0096] The adjusting rod 305 extends from the outside of the body 100 to the inside of the body 100. A transmission assembly 306 is provided inside the body 100. The transmission assembly 306 is connected to the guide plate 302 via a guide rod 307. The adjusting rod 305 rotates to drive the guide rod 307 to move and change the swing position of the guide plate 302 through the transmission assembly 306.

[0097] The hydraulic chamber 308 is provided inside the machine body 100 . The adjusting rod 305 is pulled to change the position of the moving frame 304 . Both the moving frame 304 and the adjusting rod 305 extend into the hydraulic chamber 308 .

[0098] Optionally, two one-way valves are provided inside the hydraulic chamber 308 . The two one-way valves are provided at opposite positions and both require the hydraulic oil to have a certain pressure before opening. The control of the moving frame 304 is completed by squeezing the adjusting rod 305 .

[0099] In this embodiment, the adjustment rod 305 is composed of two parts, one part of which has a corrugated cross-section and moves through the transmission assembly 306. It will not affect the transmission assembly 306 when pulled out, and drives the transmission assembly 306 to move during rotation. The other part has a circular cross-section and extends to the inside of the hydraulic chamber 308.

[0100] The transmission assembly 306 is a gear that drives two racks to move, and both ends of the guide rod 307 are movably installed between the racks and the guide plate 302. After the position of the racks changes, the guide rod 307 drives the guide plate 302 to shift in position.

[0101] In one embodiment, the twisting assembly 400 includes:

[0102] A traction member 401 is rotatably disposed inside the machine body 100, and the fiber strip passes through the traction member 401. A hollow motor 402 is disposed inside the machine body 100 to drive the traction member 401 to rotate, and the fiber strip passes through the hollow motor 402;

[0103] The floating plate 403 is movably arranged inside the body 100. The fiber strip passes through the middle of the floating plate 403 and pulls the floating plate 403 to move. An electromagnetic block 404 is arranged on the outside of the floating plate 403. The electromagnetic block 404 is arranged in a circular array inside the body 100. The electromagnetic block 404 is electromagnetically attracted to the outer edge of the floating plate 403. When the floating plate 403 is located at different heights, the aperture in the middle thereof changes.

[0104] In this embodiment, the setting of the change in the hole diameter in the middle of the floating plate 403 can be adjusted according to the size of the fiber strip after twisting. The position of the floating plate 403 is changed according to the fiber strip so that the floating plate 403 is close to the outer surface of the fiber strip, thereby ensuring the stability of the fiber strip.

[0105] Among them, the floating plate 403 can be restricted in different positions by the electromagnetic block 404, and then the state of the floating plate 403 can be adjusted accordingly. Since the floating plate 403 is restricted by the electromagnetic block 404 during use, the bonding state of the fiber strip is also restricted. The stability of the restricted fiber strip is ensured by changing the force with which the fiber strip is pressed against the fiber strip.

[0106] The position inside the body 100 for the floating plate 403 to move is set as a conical hole, the bottom size of the conical hole is larger than the upper size, the outside of the floating plate 403 is a plurality of arc blocks that can be magnetically attracted and are not connected to each other, the inside of the arc blocks is an elastic sheet, the floating plate 403 is conical when moving, and the center size of the floating plate 403 is changed according to the different restricting positions of the conical hole on the floating plate 403.

[0107] In one embodiment, the twisting assembly 400 further includes:

[0108] A clamping plate 405 is retractably disposed inside the machine body 100 and is used to clamp the fiber strips. A micro telescopic rod 406 is disposed on one side of the clamping plate 405 and is used to control the position of the clamping plate 405;

[0109] The positioning groove 407 is arranged on the inner side of the body 100 of the clamping plate 405 away from the micro telescopic rod 406. The inner side of the clamping plate 405 is provided with a clamping head 408 opened outward. When the clamping head 408 extends to the inner side of the positioning groove 407, it is restricted by the positioning groove 407 to close.

[0110] The slide rail 409 is disposed between the clamping plate 405 and the clamp 408 , and electromagnetic plates 410 are disposed on both sides of the slide rail 409 to control the position of the clamp 408 .

[0111] In this embodiment, the clamping plate 405 is pushed by the micro telescopic rod 406 to change its position, so that the clamp 408 extends to enter the interior of the positioning groove 407, and the positioning groove 407 uses the structure of its inner wall to adjust the state of the clamp 408, so that the clamp 408 clamps the fiber strip, and the clamping plates 405 located on both sides of the traction member 401 limit the twisting position of the fiber strip, and the twisting length of the fiber strip is adjusted according to the restricted position of the clamping plate 405.

[0112] Among them, the clamp 408 is set to a sliding state, and the fiber strip is pulled or contracted by controlling the length of the fiber strip during the twisting process, so as to adjust the state of the fiber strip during the twisting process and improve the quality of the fiber strip twisting.

[0113] In one embodiment, the twisting assembly 400 further includes:

[0114] A water tank 411 is provided inside the housing 100;

[0115] Roller 412, the fiber strips adhere to the inner surface of roller 412 after twisting, a conduit 413 is arranged between water tank 411 and roller 412, and the liquid inside water tank 411 wets the inner wall of roller 412 through the guide rail;

[0116] The heating plate 414 is arranged in an arc shape inside the machine body 100 to heat the fiber strips after contacting the roller 412 .

[0117] In this embodiment, the stability of the fiber strips is ensured by soaking the fiber strips and then heating them. Since the fiber content of the fiber strips is less than normal, the twisting length is shortened and the positions with less fiber content are gathered. By maintaining the stability of the fiber strips, the stability of the fiber strips during processing is ensured and deformation will not occur.

[0118] The present invention also provides a spinning method for textile production, which is used in the above-mentioned synchronous twisting spinning device, comprising the following steps:

[0119] Determine the fiber content of the fiber strips, draw the fiber strips into the synchronous twist spinning device, and multiple fiber strips enter from the feed port 200;

[0120] The fiber strip passes through the detection component 300, enters the twisting component 400, and the torsion structure 500, and then passes out of the machine body 100;

[0121] The detection component 300 generates an electrostatic force field, changes the position of the fiber strip through static electricity, obtains the position change of the fiber strip, and determines the fiber content inside the fiber strip according to the position of the fiber strip;

[0122] The twisting assembly 400 adjusts the clamping state of the fiber strip according to the fiber content inside the fiber strip, and changes the length of the fiber strip during the twisting process;

[0123] The torsion structure 500 adjusts the supporting state of the fiber strip according to the force of the fiber strip on the torsion structure 500;

[0124] The fiber strips passing through the twisting structure 500 are output from the outside of the machine body 100 and are spun through the spinning system.

[0125] In one embodiment, the detection component 300 obtains the fiber content of the fiber strip and the movement speed of the fiber strip, determines the time it takes for the fiber strip to move to the twisting component 400 based on the movement speed of the fiber strip and the distance between the detection component 300 and the twisting component 400, and determines the time it takes for the twisting component 400 to change the twisting length.

[0126] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0127] 1. During the twist spinning process, the present invention adjusts the twisting force of the fiber strip during the twisting process by obtaining the fiber content in the fiber strip before twisting, so that the fiber strip matches the twisting force during the twisting process, thereby ensuring the twisting stability of the fiber strip and improving the twisting quality when the fiber content inside the fiber strip is different.

[0128] 2. Before the fiber strip is twisted, static electricity is generated by the detection component 300 to change the position of the fiber strip. Due to the different fiber contents of the fiber strips, they move to different positions under the influence of static electricity, and the fiber content inside the fiber strip is judged to accurately detect the fiber content inside the fiber strip, thereby ensuring the accuracy of the detection.

[0129] 3. Adjust the twisting state of the fiber strips according to the different fiber contents inside the fiber strips. During the twisting process of the fiber strips, adjust the twisting length of the fiber strips to change the twisting state of the fiber strips, and then control the twisting changes of the fiber strips to ensure that fiber strips with different contents can be twisted stably, and further control the twisting quality of the fiber strips.

[0130] 4. The twisting length of the fiber strips can be adjusted through the control component to ensure the accuracy of the fiber strips during the twisting process. Automatic adjustments can be made according to the state of the fiber strips to ensure that the twisting length of the fiber strips is consistent with the fiber strip content. By controlling multiple fiber strips, each fiber strip can be controlled individually to ensure the spinning quality.

[0131] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
