[0009] As a preferred technical solution of this utility model: there are two second springs, and the two second springs are symmetrically arranged with the slider as the center.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The tension adjustment structure of this false twister system utilizes adjustment components installed on the inner walls of the first, second, and third friction wheels to achieve tension control of the yarn. By pulling the top plate, the convex pin retracts via a steel wire rope, allowing the first, second, and third friction wheels to move flexibly along the grooves on the outer wall of the shaft. Once adjusted to the appropriate position, releasing the top plate causes the convex pin to spring back and remain fixed. This allows for fine-tuning of the yarn tension by adjusting the gap between the stacked first, second, and third friction wheels, thereby improving the stability and consistency of product quality.
[0013] 2. The tension adjustment structure of this false twister system, through the setting of the balancing component, further ensures operational stability. When the yarn deviates during the false twisting process, the slider slides in the guide groove to compress the second springs on both sides. The elastic force of the second springs causes the slider to reset, driving the yarn back to its original position. At the same time, the addition of a counterweight allows for flexible adjustment of the slider weight, enhancing the adaptability to different working conditions and avoiding production interruptions, equipment wear, and material waste caused by yarn deviation, thereby effectively improving production efficiency and equipment lifespan.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 - Figure 6 A tension adjustment structure for a false twister system includes a transmission housing 1. A motor 2 is fixedly installed at the bottom of the transmission housing 1. A sprocket 3 is fixedly sleeved on the outer edge of the output shaft of the motor 2. A first rotating shaft 4 is fixedly sleeved on the inner wall of the sprocket 3. A chain 5 is provided on the outer wall of the sprocket 3. A sliding groove 6 and a slot 7 are respectively opened on the outer wall of the first rotating shaft 4. A first friction wheel 8 is provided on the outer wall of the first rotating shaft 4. A second rotating shaft 9 and a third rotating shaft 11 are respectively provided in the inner cavity of the transmission housing 1. A second friction wheel 10 is provided on the outer wall of the second rotating shaft 9. A third friction wheel 12 is provided on the outer wall of the third rotating shaft 11. A connecting rod 13 is fixedly assembled on the outer wall of the transmission housing 1. A square frame 14 is fixedly installed on the top of the connecting rod 13. An adjustment component 15 is provided on the inner wall of the first friction wheel 8. A balancing component 16 is provided on the inner wall of the square frame 14. A first guide tube 17 is fixedly installed on the top of the transmission housing 1.
[0025] In the above structure, by setting the adjustment component 15, after the yarn passes through the first guide tube 17, it is first twisted counterclockwise by the second friction wheel 10, and then twisted clockwise by the first friction wheel 8, which rotates clockwise at the top of the second friction wheel 10. The third friction wheel 12, which rotates clockwise at the top of the first friction wheel 8, will twist the third segment of the yarn clockwise. The first friction wheel 8, the second friction wheel 10 and the third friction wheel 12 are stacked in sequence to complete the false twist of the yarn.
[0026] In a preferred embodiment: the adjusting assembly 15 includes a cylindrical body 151, the inner cavity of the cylindrical body 151 is provided with a convex pin 152 and a first spring 153 respectively, the outer wall of the convex pin 152 is provided with a wire rope 154, the inner wall of the first friction wheel 8 is rotatably connected with a pulley 155, and the top of the first friction wheel 8 is fixedly installed with a top plate 156.
[0027] In a preferred embodiment: the cylinder 151, the convex pin 152, the first spring 153, the wire rope 154 and the pulley 155 are regarded as a set of movable components, and the number of such movable components is four, which are respectively arranged opposite to each other. One end of the four first springs 153 is connected to the convex pin 152, and the other end is connected to the inner wall of the cylinder 151. The outer wall of the four convex pins 152 is slidably fitted to the inner wall of the cylinder 151. One end of the four wire ropes 154 is connected to the convex pin 152, and the other end is connected to the top plate 156. The outer wall of the four convex pins 152 is adapted to the inner wall of the slot 7.
[0028] In the above structure, by setting the convex pin 152, when the top plate 156 is pulled, the top plate 156 will drive one end of the four steel wire ropes 154 to extend towards the outer wall of the first friction wheel 8. The other end of the extended steel wire ropes 154 will drive the convex pin 152 to slide along the inner wall of the cylinder 151. The sliding will drive the first spring 153 to compress, and then the convex pin 152 will retract into the inner cavity of the cylinder 151. Then, when the first friction wheel 8 moves to the corresponding slot 7 in the adjustment position, the top plate 156 is released, and the convex pin 152 returns to the inner wall of the slot 7 under the compression and rebound of the first spring 153, thereby fixing the adjusted first friction wheel 8 to the outer wall of the first rotating shaft 4.
[0029] In a preferred embodiment: the balancing assembly 16 includes a guide rod 161, the outer wall of the guide rod 161 is provided with a guide groove 162, the inner wall of the guide rod 161 is provided with a second spring 163 and a slider 164, the top of the slider 164 is provided with a second guide tube 165, the top of the slider 164 is fixedly installed with a fixing post 166, and the outer wall of the fixing post 166 is movably sleeved with a counterweight 167.
[0030] In a preferred embodiment: there are two second springs 163, and the two second springs 163 are symmetrically arranged with the slider 164 as the center. One end of the two second springs 163 overlaps with the inner wall of the guide rod 161, and the other end overlaps with the outer wall of the slider 164. The outer wall of the slider 164 is slidably fitted to the inner wall of the guide groove 162. There are two fixed posts 166 and two counterweights 167, and the two fixed posts 166 and two counterweights 167 are symmetrically arranged with the second guide tube 165 as the center.
[0031] In the above structure, by setting the fixed post 166, after the yarn is transmitted to the inner cavity of the second guide tube 165, when the yarn is false-twisted, if the first friction wheel 8, the second friction wheel 10 and the third friction wheel 12 deviate, the slider 164 will slide along the inner wall of the convex pin 152 under the thrust of the yarn. At this time, the second springs 163 set on both sides of the outer wall of the slider 164 will be compressed, so that the slider 164 will be kept in balance under the elastic force of the second springs 163 on both sides, and the yarn will be reset. At the same time, by placing two fixed posts 166 with the same number of counterweights 167, the weight of the slider 164 is increased, so that the yarn will not deviate when false-twisting.
[0032] In a preferred embodiment: there are three sprockets 3, and each sprocket 3 is respectively set on the outer wall of the first rotating shaft 4, the second rotating shaft 9 and the third rotating shaft 11 to form a triangle. The outer edge teeth of the three sprockets 3 are meshed with the outer edge of the chain 5. The adjusting component 15 is regarded as a set of movable components, and the movable components are respectively set on the inner wall of the first friction wheel 8, the second friction wheel 10 and the third friction wheel 12. There are three slide grooves 6, and each slide groove 6 is opened on the outer wall of the first rotating shaft 4, the second rotating shaft 9 and the third rotating shaft 11 and adapted to the inner wall of the first friction wheel 8, the second friction wheel 10 and the third friction wheel 12.
[0033] In the above structure, by setting the first friction wheel 8, the second friction wheel 10, and the third friction wheel 12, the motor 2 is started, causing the motor 2 to drive the sprocket 3 to rotate. The sprocket 3 drives the chain 5 on its outer edge to rotate, and the rotating chain 5 drives the other two sets of sprockets 3 to rotate. This causes the first shaft 4 to rotate clockwise, the second shaft 9 to rotate counterclockwise, and the third shaft 11 to rotate clockwise. Consequently, the first friction wheel 8 twists the first section of the yarn clockwise, and the second friction wheel 10, which is located on top of the first friction wheel 8, twists the second end of the yarn counterclockwise. The yarn is twisted clockwise, and then the third friction wheel 12, which is set on the top of the second friction wheel 10, twists the third segment of the yarn clockwise. By stacking the first friction wheel 8, the second friction wheel 10 and the third friction wheel 12, the yarn is twisted in multiple segments to achieve false twist. At the same time, when it is necessary to adjust the tension of the yarn, the adjustment component 15 set on the inner wall of the first friction wheel 8, the second friction wheel 10 and the third friction wheel 12 is operated to adjust the gap between each stack. The larger the gap, the smaller the tension of the yarn, and the smaller the gap, the larger the tension, thereby adjusting the tension of the yarn.
[0034] Working principle: First, the yarn is passed through the first guide tube 17 at the top of the transmission box 1, so that the yarn passes through the second friction wheel 10, the first friction wheel 8 and the third friction wheel 12 in sequence, and finally passes through the second guide tube 165 in the balancing assembly 16, so that an appropriate number of counterweights 167 are placed on the fixed column 166 as required to ensure that the weight of the slider 164 meets the balance requirements when the yarn is falsely twisted. Then, the motor 2 is started, so that the output shaft of the motor 2 drives the sprocket 3 fixedly sleeved on the outer wall to rotate. Since the three sprockets 3 are driven by the chain 5 and are respectively set on the outer walls of the first rotating shaft 4, the second rotating shaft 9 and the third rotating shaft 11, forming a three-way transmission, the yarn is driven by the chain 5. The angular layout allows the rotation of sprocket 3 to drive the chain 5, which in turn drives the other two sets of sprockets 3 to rotate. The first shaft 4 rotates clockwise, causing the first friction wheel 8, which is fixed on its outer wall, to twist the first segment of the thread that passes through it clockwise. Then, because the second shaft 9 rotates counterclockwise, it drives the second friction wheel 10 to twist the second end of the thread counterclockwise. The third shaft 11 rotates clockwise, causing the third friction wheel 12 to twist the third segment of the thread clockwise. Through the stacked arrangement of the first friction wheel 8, the second friction wheel 10, and the third friction wheel 12, the twisting of multiple segments of the thread is achieved, completing the false twisting operation.
[0035] Secondly, if it is necessary to adjust the tension of the wire, taking the first friction wheel 8 as an example, pull the top plate 156, causing the top plate 156 to drive one end of the four steel wire ropes 154 to extend towards the outer wall of the first friction wheel 8, thereby causing the other end of the steel wire ropes 154 to pull the convex pin 152 to slide along the inner wall of the cylinder 151, causing the first spring 153 to be compressed, causing the convex pin 152 to retract into the inner cavity of the cylinder 151. At this time, the position of the first friction wheel 8 can be adjusted by moving it along the groove 6 on the outer wall of the first rotating shaft 4. When the first friction wheel 8 moves to the corresponding slot 7, the top plate 156 is released, so that the convex pin 152 returns to the inner wall of the slot 7 under the compression and rebound of the first spring 153, thereby fixing the adjusted first friction wheel 8 to the outer wall of the first rotating shaft 4. Similarly, the same operation is performed on the adjustment components 15 of the inner walls of the second friction wheel 10 and the third friction wheel 12. By adjusting the gap between each stack, the tension of the yarn is adjusted. The larger the gap, the smaller the tension of the yarn, and the smaller the gap, the larger the tension.
[0036] Then, during the false twisting process, if the yarn deviates from the first friction wheel 8, the second friction wheel 10, and the third friction wheel 12, the thrust of the yarn will cause the slider 164 to slide along the guide groove 162 on the inner wall of the guide rod 161. This will cause the second springs 163 on both sides of the outer wall of the slider 164 to be compressed. Then, under the elastic force of the second springs 163, the slider 164 will be kept in balance, and the yarn will be driven to return to its original position, ensuring the stable progress of the false twisting process.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
