Description

Technical Field

[0001] The present invention relates to the technical field of yarn production, and more particularly to a false twister assembly and a texturing machine having the false twister assembly. Background Art

[0002] The false twister assembly is a key component in chemical fiber filament processing, primarily used in the false twist texturing process of stretch yarn machines. A friction-disc false twister employs three stacked friction discs that directly contact the yarn surface, twisting it. These discs rotate in the same direction, pushing the yarn back and forth, creating a false twist. The yarn is then heated and set to impart a certain elasticity. During the false twist texturing process, the working discs interact with each other, creating friction between the outer periphery of the false twister and the yarn, which in turn creates friction and twist.

[0003] The effect of the working disc in a false twister on the friction twisting of the yarn is primarily determined by several factors, including the pressure between the disc and the yarn and the disc's rotational speed. The disc's speed is typically driven by a belt and not individually adjusted. Once installed, the disc's relative position cannot be adjusted, nor can the yarn's friction twisting parameters be adjusted. When adjustments are necessary, they are typically made by simply replacing the disc, a relatively cumbersome process that prevents fine-tuning of the yarn's friction twisting.

[0004] In addition, by actively adjusting the tension of the yarn, the pressure between the yarn and the working disk can be increased, thereby also enhancing the friction twisting effect of the working disk on the yarn. However, the range of tension adjustment is limited, and excessive or insufficient tension will increase the risk of thread breakage.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0006] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a false twister assembly, a texturing machine and a texturing control method.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A false twister assembly includes a base, a driving shaft, a fixed driven shaft, and a dynamic driven shaft. The driving shaft and the fixed driven shaft are both rotatably connected to the base. The base is slidably connected to a slide. The slide has an arc-shaped sliding track, and the axis of the sliding track is coaxial with the axis of the driving shaft. The dynamic driven shaft is rotatably connected to the slide. The driving shaft, the fixed driven shaft, and the dynamic driven shaft are parallel to each other and can rotate synchronously. During the sliding of the slide along the sliding track, the distance between the dynamic driven shaft and the fixed driven shaft changes, and the two shafts have a close position and a distant position.

[0009] The driving shaft, the fixed driven shaft and the dynamic driven shaft are all fixedly mounted with a plurality of working disks, which are alternately stacked. The outer peripheries of the fixed driven shaft and the dynamic driven shaft are rotatably connected with a plurality of friction wheels, and the working disks and friction wheels on the outer peripheries of the fixed driven shaft and the dynamic driven shaft are arranged opposite to each other, and a gap is formed between the relative working disks and friction wheels.

[0010] The present invention is further configured such that when the driven shaft moves from a distant position to an approaching position, the distance between the driven shaft and the fixed driven shaft becomes smaller, and the gap between the working disk and the friction wheel gradually becomes smaller; when the driven shaft moves from an approaching position to a distant position, the distance between the driven shaft and the fixed driven shaft becomes larger, and the gap between the working disk and the friction wheel gradually becomes larger.

[0011] The present invention is further configured such that when the driven shaft is located in a close position, the outer peripheral surfaces of the working disc and the friction wheel abut against each other and can roll relative to each other.

[0012] The present invention is further configured such that the working disk on the periphery of the fixed and driven shafts is working disk two, the working disk on the periphery of the driven shafts is working disk three, the friction wheel on the periphery of the fixed and driven shafts is friction wheel one, and the friction wheel on the periphery of the driven shafts is friction wheel two; the working disk two corresponds one-to-one with the friction wheel two, and the working disk three corresponds one-to-one with the friction wheel.

[0013] The present invention is further configured such that a driving wheel 1 and a driving wheel 2 are mounted on the lower end of the driving shaft, a driven wheel 1 is mounted on the lower end of the fixed driven shaft, and a driven wheel 2 is mounted on the lower end of the fixed driven shaft, a transmission belt 1 is used to transmit power between the driving wheel 1 and the driven wheel 1, and a transmission belt 2 is used to transmit power between the driving wheel 2 and the driven wheel 2;

[0014] The present invention is further configured such that a linkage wheel is further installed at the lower end of the driving shaft, and the linkage wheel is transmission-connected to the driver for driving the driving shaft, the fixed driven shaft and the dynamic driven shaft to rotate synchronously.

[0015] The present invention is further configured to include an adjuster, which is installed on the base and has a telescopically adjustable adjustment rod; a linkage block is fixedly connected to the outer side of the slide, and the end of the adjustment rod is against the linkage block, which is used to drive the linkage block and the slide to slide synchronously; the linkage block is elastically pressed against a spring on the side facing away from the adjustment rod.

[0016] The present invention is further configured such that the linkage block and the adjustment rod are both located on the side of the slide facing away from the active shaft, and the adjustment direction of the adjustment rod is set along the tangential direction of the sliding track; the adjustment rod is located on the side of the linkage block facing the fixed driven shaft, and the spring is located on the side of the linkage block facing away from the driven shaft; the regulator is driven and controlled by a servo motor, and the telescopic adjustment amount of the adjustment rod can be adjusted and controlled.

[0017] The present invention is further configured such that the outer periphery of the driving shaft is coaxially rotatably connected to a rotating sleeve; and a fixing frame is fixedly connected between the rotating sleeve and the sliding seat.

[0018] The present invention also provides a texturing machine, comprising the false twister assembly as described above, and also comprising a roller assembly 1, a roller assembly 2 and a tension detector, wherein the roller assembly 1 and the roller assembly 2 are respectively located on the input side and the output side of the false twister assembly, and are used to actively transport the yarn; the tension detector is located between the roller assembly 1 and the input side of the false twister assembly, and is used to detect the tension of the yarn.

[0019] The present invention is further configured such that the yarn is false-twisted by the false twister assembly. When the tension between the input side of the false twister assembly and the roller assembly 1 increases, it indicates that the false twister assembly has excessively twisted the yarn by friction. The regulator operates to move the driven shaft away from the fixed driven shaft, thereby reducing the friction effect of the working disc on the yarn and alleviating the excessive twisting.

[0020] When the tension between the input side of the false twister assembly and the roller assembly 1 becomes smaller, it means that the friction twisting of the yarn by the false twister assembly is insufficient; by working the regulator, the dynamic driven shaft is brought close to the fixed driven shaft, and the friction effect of the working disk on the yarn is increased to alleviate the situation of insufficient twisting; by continuously adjusting the twisting condition of the false twister assembly, the twisting state of the false twister assembly is maintained in a stable state.

[0021] In summary, the present invention has the following beneficial effects:

[0022] In this solution, by installing a friction wheel, the friction wheel can cooperate with the corresponding working disk to form a gap between the friction wheel and the working disk for the yarn to pass through. The two sides of the yarn can be supported by the friction wheel and the working disk. The outer peripheral surface of the friction wheel and the working disk can jointly provide limited support for the yarn to increase the friction force on the yarn, thereby increasing the friction effect on the yarn, and thereby reducing the friction and slippage between the yarn and the working disk to improve the twisting efficiency of the yarn.

[0023] By sliding adjustment of the driven shaft, the distance between the driven shaft and the fixed driven shaft can be adjusted to adjust the relative distance between the working disks on the corresponding rotating shafts, and then the size of the gap between the friction wheel and the working disk can be adjusted, and the degree of friction restriction of the friction wheel and the working disk on the yarn can be adjusted. The friction effect of the fixed working disk and the friction wheel on the yarn can be adjusted to change the twisting of the yarn, and the size of the friction force on the yarn can be adjusted to adjust the twisting condition.

[0024] The driven shaft adopts a movable and adjustable structure, and during the adjustment process of the driven shaft, the driving shaft, the fixed driven shaft and the driven shaft can always keep rotating synchronously, ensuring that the motion state of the three shafts is the same, keeping the speed state consistent, reducing the variables in the adjustment process, and achieving a stable adjustment effect.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] This embodiment discloses a false twister assembly, referring to Figures 1-9 As shown, it includes a base 5, a driving shaft 1, a fixed driven shaft 2 and a dynamic driven shaft 3. The driving shaft 1 and the fixed driven shaft 2 are both rotatably connected to the base 5 and are roughly vertically arranged; the dynamic driven shaft 3 is also vertically arranged and can rotate relative to the base 5, and the dynamic driven shaft 3 is a movable structure with a slide 6 as a supporting carrier and can move relative to the base 5.

[0040] Reference Figure 5 、 Figure 6 As shown, a sliding groove 60 is provided in the base 5, and the slide 6 is slidably mounted in the sliding groove 60 to achieve a sliding connection with the base 5. The sliding groove 60 has an arc-shaped structure, and the sliding track of the slide 6 is arc-shaped, and the axis of the sliding track is coaxial with the axis of the driving shaft 1.

[0041] Reference Figure 1-Figure 3As shown, the driven shaft 3 is rotatably connected to the slide 6, in an upright position. Several working disks 4 are mounted on the driving shaft 1, the fixed driven shaft 2, and the driven driven shaft 3. The working disks 4 of the driving shaft 1, the fixed driven shaft 2, and the driven driven shaft 3 are alternately stacked. The working disks 4 cooperate with each other to perform false twisting on the yarn passing through them. The working disks 4 of the driving shaft 1, the fixed driven shaft 2, and the driven driven shaft 3 are respectively designated as working disk 1 41, working disk 2 42, and working disk 3 43.

[0042] The driving shaft 1, the fixed driven shaft 2, and the driven driven shaft 3 are parallel to each other, forming an isosceles triangle. The distance between the driving shaft 1 and the fixed driven shaft 2 is equal to the distance between the driving shaft 1 and the driven driven shaft 3, forming the two legs of the isosceles triangle. The distance between the driven driven shaft 3 and the fixed driven shaft 2 varies, thereby adjusting the tightness between the three shafts, thereby adjusting the friction force on the yarn and thus adjusting the twist.

[0043] During the sliding process of the slide 6 along the sliding track, the distance between the driven shaft 3 and the driving shaft 1 remains the same, and the distance between the driven shaft 3 and the fixed driven shaft 2 changes, and has a close position and a far position, wherein the close position refers to Figure 5 As shown, away from the position reference Figure 6 shown.

[0044] Reference Figure 2 、 Figure 3 As shown, a plurality of friction wheels 9 are rotatably connected to the outer peripheries of the fixed driven shaft 2 and the driven driven shaft 3. The working disks 4 and the friction wheels 9 on the outer peripheries of the fixed driven shaft 2 and the driven driven shaft 3 are arranged opposite to each other, and a gap 900 is formed between the relative working disks 4 and the friction wheels 9, and the gap 900 can be adjusted.

[0045] Specifically, refer to Figure 4 As shown, the working disk 4 on the periphery of the fixed and driven shafts 2 is working disk 2 42, the working disk 4 on the periphery of the driven and driven shafts 3 is working disk 3 43, the friction wheel 9 on the periphery of the fixed and driven shafts 2 is friction wheel 1 91, and the friction wheel 9 on the periphery of the driven and driven shafts 3 is friction wheel 2 92. Working disk 2 42 corresponds one-to-one with friction wheel 2 92, and working disk 3 43 corresponds one-to-one with friction wheel 1 91. A gap 900 for yarn to pass through can be formed between the corresponding outer peripheral surfaces.

[0046] The friction wheel 9 cooperates with the corresponding working disk 4 to jointly provide limited support to the yarn on the outer peripheral surface of the friction wheel 9 and the working disk 4, so as to increase the friction force on the yarn, thereby increasing the friction effect on the yarn, and reducing the friction and slippage between the yarn and the working disk 4, so as to improve the twisting efficiency of the yarn.

[0047] Reference Figure 4-Figure 6As shown, during the adjustment of the driven output shaft 3 relative to the fixed output shaft 2 , the width of the gap 900 can also be adjusted.

[0048] When the driven shaft 3 moves from the distant position to the approaching position, the distance between the driven shaft 3 and the fixed driven shaft 2 decreases, and the gap 900 between the working disk 4 and the friction wheel 9 gradually decreases, thereby increasing the friction between the working disk 4 and the friction wheel 9 on the yarn, thereby increasing the twisting effect on the yarn. When the driven shaft 3 moves from the approaching position to the distant position, the distance between the driven shaft 3 and the fixed driven shaft 2 increases, and the gap 900 between the working disk 4 and the friction wheel 9 gradually increases, thereby reducing the friction between the working disk 4 and the friction wheel 9 on the yarn, thereby reducing the twisting effect on the yarn.

[0049] Further, refer to Figure 5 As shown, when the driven shaft 3 is in the close position, the distance between the driven shaft 3 and the fixed driven shaft 2 is the smallest. At this time, the outer circumferential surfaces of the working disc 4 and the friction wheel 9 abut against each other, allowing them to roll relative to each other. This directly acts as a circumferential counteraction on the yarn, thereby increasing the pressure on the yarn and thus increasing the friction force on the yarn. During the adjustment process, it is important to avoid excessive pressure from the working disc 4 and the friction wheel 9 on the yarn to prevent excessive wear of the yarn.

[0050] Reference Figure 8 As shown, the slide 6 is roughly located in the middle of the sliding track. At this point, the driving shaft 1, the fixed driven shaft 2, and the driven driven shaft 3 form a roughly equilateral triangle. As the slide 6 slides upward, the distance between the driven driven shaft 3 and the fixed driven shaft 2 increases, which in turn increases the distance between the second working disk 42 and the third working disk 43. The width of the gap 900 between the working disk 4 and the friction wheel 9 also increases, reducing the compression of the yarn in the middle and the friction effect on the yarn. The slippage between the working disk and the yarn increases, and the twisting effect on the yarn is reduced.

[0051] When the slide 6 slides downward, the distance between the dynamic driven shaft 3 and the fixed driven shaft 2 will become smaller, and the distance between the working disk 2 42 and the working disk 3 43 will become smaller, and the width of the gap 900 between the working disk 4 and the friction wheel 9 will also become smaller, the degree of compression on the middle yarn will become greater, the friction effect on the yarn will also become greater, the slippage between the working disk and the yarn will be reduced, and the twisting effect on the yarn will also be enhanced, thereby improving the twisting effect.

[0052] Reference Figure 2 、 Figure 3 As shown, in this embodiment, the driving shaft 1, the fixed driven shaft 2 and the dynamic driven shaft 3 can maintain synchronous rotation, and the slight slip of the slide 6 and the dynamic driven shaft 3 basically has no effect on the rotation speed of the three shafts.

[0053] Reference Figure 1-Figure 3 、 Figure 8 As shown, a linkage pulley 11 is mounted at the lower end of the driving shaft 1. This linkage pulley 11 is in transmission connection with the driver and can drive the driving shaft 1, the fixed driven shaft 2, and the driven driven shaft 3 to rotate synchronously, serving as the active power input. Driving pulley 1 12 and driving pulley 2 13 are mounted at the lower end of the driving shaft 1. Driven pulley 1 21 is mounted at the lower end of the fixed driven shaft 2, and driven pulley 2 31 is mounted at the lower end of the driven driven shaft 3. A transmission belt 121 drives the driving pulley 12 and driven pulley 1 21. The axis positions of the driving pulley 12 and driven pulley 1 21 are fixed, and the transmission belt 121 can drive the driving shaft 1 and the fixed driven shaft 2 to rotate synchronously.

[0054] Reference Figure 1-Figure 3 、 Figure 8 As shown, the transmission belt 2 131 is used to transmit power between the second driving wheel 13 and the second driven wheel 31. The distance between the axes of the first driving wheel 12 and the second driving wheel 13 is also kept consistent, thereby driving the driving shaft 1 and the driven shaft 3 to rotate synchronously via the second transmission belt 131. When the driven shaft 3 slides along the slide 6, the transmission belt 2 131 can maintain normal transmission.

[0055] Through two sets of transmission belts, transmission belt 1 121 and transmission belt 2 131, transmission between the three rotating shafts can be achieved, and the three rotating shafts can always be kept in synchronous rotation, so as to achieve synchronous rotation of working disk 1 41, working disk 2 42, and working disk 3 43, and jointly twist the yarn.

[0056] In this embodiment, the false twister assembly further includes an adjuster 7 mounted on the base 5 and having a retractable adjustment rod 71. The adjuster 7 is driven by a servo motor or a stepper motor. The retractable adjustment amount of the adjustment rod 71 can be adjusted, thereby adjusting the position of the slide 6 and the driven shaft 3.

[0057] Reference Figure 9 As shown, a linkage block 61 is fixedly connected to the outer side of the slide 6, and a linkage groove 62 is also defined in the slide 6 to allow the slide 6 to be adjusted. The housing of the adjuster 7 is fixedly connected to the base 5 as a whole, and an adjustment channel 710 is also defined in the base 5. The adjustment rod 71 is slidably connected to the adjustment channel 710, and the adjustment channel 710 is connected to the linkage groove 62. The end 711 of the adjustment rod 71 can extend into the linkage groove 62, and the end 711 of the adjustment rod 71 can abut against the linkage block 61, which can drive the linkage block 61 and the slide 6 to slide synchronously.

[0058] A spring 63 is elastically pressed against the side of the linkage block 61 facing away from the adjustment rod 71. The spring 63 applies an elastic force to the linkage block 61, thereby balancing the forces on both sides to maintain the fixed position of the linkage block 61 and the slide 6. Furthermore, a receiving groove 631 is formed on the side wall of the linkage groove 62, into which the end of the spring 63 can be inserted, thereby maintaining the position stability of the spring 63.

[0059] Reference Figure 9 As shown, the linkage block 61 and the adjustment rod 71 are both located on the side of the slide 6 facing away from the driving shaft 1. The adjustment direction of the adjustment rod 71 is set along the tangent direction of the sliding track. The adjustment rod 71 can be adjusted back and forth, and the end 711 of the adjustment rod 71 can push the linkage block 61 to move, thereby driving the movement of the driven shaft 3, the slide 6, and the slide 6.

[0060] Reference Figure 9 As shown, the adjustment rod 71 is located on the side of the linkage block 61 facing the fixed and driven shafts 2, and the spring 63 is located on the side of the linkage block 61 facing away from the driven shaft 2. The upward movement of the linkage block 61 is blocked by the end 711 of the adjustment rod 71. During the downward movement of the linkage block 61, the spring 63 elastically blocks the side direction of the linkage block 61, thereby allowing the linkage block 61 to elastically deflect away from the fixed and driven shafts 2.

[0061] When the driven shaft 3 moves toward the fixed driven shaft 2, the force of the driven shaft 3 toward the fixed driven shaft 2 can apply pressure through the spring 63, and the spring 63 can apply force between the working disk 2 42 and the working disk 3 43, thereby limiting the gap 2 402 between the working disk 2 42 and the working disk 3 43 to a smaller range; and when the gap 2 402 between the working disk 2 42 and the working disk 3 43 may be too small, the linkage block 61 can elastically deflect toward the direction of the spring 63, and through the elastic deflection toward the direction of the spring 63, it plays a role of elastic buffering.

[0062] Example 2

[0063] This embodiment discloses a false twister assembly. Figure 10 A rotating sleeve 65 is coaxially connected to the outer periphery of the driving shaft 1 , and the rotating sleeve 65 is only supported for rotation and does not rotate along with the driving shaft 1 .

[0064] A fixing frame 64 is fixedly connected between the rotating sleeve 65 and the sliding seat 6 , and a clearance groove 641 is provided in the base 5 for the fixing frame 64 to pass through and allow the fixing frame 64 to deflect and move.

[0065] The fixing frame 64 and the rotating sleeve 65 can support the slide 6 , so that the slide 6 can be supported and guided more stably, thereby improving the adjustment stability of the slide 6 and the driven shaft 3 .

[0066] Example 3

[0067] This embodiment discloses a texturizing machine, referring to Figure 11 As shown, it includes the false twister assembly 100 as in the first or second embodiment, and also includes a roller assembly 1 200, a roller assembly 2 300, and a tension detector 800. Among them, the false twister assembly 100 can false twist the yarn, the roller assembly 1 200 and the roller assembly 2 300 can actively transport the yarn; and the tension detector 800 can detect the tension of the yarn.

[0068] Reference Figure 11 As shown, roller assembly 1 200 and roller assembly 2 300 are located on the input and output sides of the false twister assembly 100, respectively, and are capable of actively transporting the yarn. The false twister assembly 100 twists the yarn. During the twisting process, the yarn tension increases, specifically the tension between the input side of the false twister assembly 100 and roller assembly 1 200. A tension detector 800 is located between roller assembly 1 200 and the input side of the false twister assembly 100 and is used to detect the yarn tension. Changes in the tension reflect the yarn tension applied by the false twister assembly 100.

[0069] Reference Figure 11 As shown, the tension detector 800 includes two guide wheels 801, a tension wheel 802 and a sliding displacement sensor 803. The tension wheel 802 is located between the two guide wheels 801. The sliding displacement sensor 803 has a detection end 804 that can be elastically extended. The tension wheel 802 is installed at the detection end 804 of the sliding displacement sensor 803.

[0070] When the yarn tension increases, the yarn tension between the two guide wheels 801 will also increase, and the pressure on the tension wheel 802 will gradually increase, applying pressure to the detection end 804 of the sliding displacement sensor 803. The changes in the detection end 804 reflect the parameter changes of the sliding displacement sensor 803, and then can reflect the changes in the yarn tension between the two guide wheels 801, and reflect the changes in the yarn tension during the twisting process.

[0071] On the contrary, when the yarn tension becomes smaller, the yarn tension between the two guide wheels 801 will also become smaller, and the pressure on the tension wheel 802 will gradually decrease. The change in the detection end 804 reflects the parameter change of the sliding displacement sensor 803, which can reflect the change in yarn tension during the twisting process.

[0072] This embodiment also discloses a texturing control method, which uses the texturing machine in the above embodiment to perform false twisting on the yarn;

[0073] During the texturing machine's operation, the yarn is frictionally twisted by the working discs 4 of the false twister assembly 100, causing the yarn tension between the input side of the false twister assembly 100 and the roller assembly 1 200 to change. After the machine is balanced, the yarn tension between the input side of the false twister assembly 100 and the roller assembly 1 200 remains stable, meaning that the parameter reflected by the sliding displacement sensor 803 remains substantially stable.

[0074] When the parameter reflected by the sliding displacement sensor 803 changes, indicating that the tension of the yarn between the input side of the false twister assembly 100 and the roller assembly 1 200 increases, it means that the friction twisting of the yarn by the working disks 4 of the false twister assembly 100 has increased, resulting in excessive twisting. Through the operation of the regulator 7, the regulating rod 71 extends a certain amount, pushing the linkage block 61 and the slide 6 to move, that is, the driven shaft 3 moves away from the fixed driven shaft 2, the distance between the working disks 2 42 and 3 43 increases, and the tightness between the three groups of working disks 4 decreases, reducing the friction on the yarn and the effect of yarn twisting, thereby alleviating the excessive twisting.

[0075] Conversely, when the parameter detected by the sliding displacement sensor 803 changes, indicating that the tension of the yarn between the input side of the false twister assembly 100 and the roller assembly 1 200 has decreased, it indicates that the degree of frictional twisting of the yarn by each working disk 4 of the false twister assembly 100 has decreased, resulting in insufficient twist. The adjustment lever 71 retracts a certain amount through the operation of the regulator 7, and the spring 63 pushes the linkage block 61 and the slide 6 to move, thereby moving the driven shaft 3 closer to the fixed driven shaft 2, shortening the distance between the working disks 2 42 and 3 43, and tightening the three sets of working disks 4. This increases the friction on the yarn, improves the twisting effect on the yarn, and alleviates the insufficient twist. Subsequently, the twisting of the false twister assembly 100 is continuously adjusted according to the parameter changes detected by the sliding displacement sensor 803 to maintain the twisting state of the false twister assembly 100 in a stable state.

[0076] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
