Description

Technical Field

[0001] This invention belongs to the field of textile machinery technology, and in particular relates to a tension self-adjusting device for a texturing machine and its usage method. Background Technology

[0002] Texturing machines are commonly used equipment in the post-processing of synthetic fiber filaments. They are mainly used to perform false twisting texturing on synthetic fiber filaments such as polyester and nylon, giving the raw yarn a certain degree of bulkiness, elasticity, and crimping properties. During the texturing process, the yarn needs to go through feeding, heating, cooling, false twisting, drawing, setting, oiling, and winding in sequence. The operating speed, draw ratio, and guide path of each process will jointly affect the stress state of the yarn. Tension control is an important factor in ensuring the stable operation of the yarn. Existing texturing machines usually have a [missing information - likely a feature or design feature] in the yarn path. The tension range is maintained by adjusting the yarn wrap angle, guide position, roller speed, or holding force through a yarn guide, tension bar, tension sensor, friction wheel, adjusting roller, or servo drive mechanism. Some equipment also uses an electronic control system to collect tension signals and adjust the drafting or winding zone according to preset parameters. In regular production, operators set initial tension parameters according to the raw yarn specifications, processing type, machine speed, and winding requirements. They then manually correct the corresponding workstations by inspecting the yarn vibration, fuzz, breakage, and winding formation.

[0003] The core deficiency of existing texturing machine tension adjustment methods lies in the lag in tension adjustment response. When the yarn is running at high speed, it is affected by batch differences in raw yarn, oil condition, temperature fluctuations in the heating chamber, changes in false twist friction, and changes in winding diameter. The adjustment mechanism only begins to compensate after the tension has deviated from the appropriate range, and the amount of compensation is easily limited by mechanical clearance, transmission inertia, and control precision, making it difficult to return to the stable range in time. When the tension is too high, the yarn is easily overstretched, affecting the internal structure of the fiber. Subsequent products may experience a decrease in strength, uneven elasticity, or an increase in breakage. When the tension is too low, the yarn runs loosely, the false twist is unstable, and the winding formation is prone to loose loops, overlapping yarns, or uneven end faces. Although operators can adjust parameters based on experience, such adjustments usually occur after abnormal phenomena occur and cannot continuously, actively, and synchronously suppress tension fluctuations. Therefore, under high-speed, multi-station, and frequent product switching production conditions, existing equipment still struggles to maintain consistent tension at each spindle position for a long time, affecting the stability of texturing yarn processing quality.

[0004] To address this issue, we provide a tension self-adjusting device for a texturing machine and its usage method. Summary of the Invention

[0026] The beneficial effects of this invention are as follows: This invention drives the compensation roller support plate to rise or fall through an electric push rod mechanism, causing a position change at one end of the variable diameter compensation roller, thereby changing the wrapping position and conveying path length of the yarn bundle when it passes through the variable diameter compensation roller; at the same time, the yarn bundle can move along the axial direction of the variable diameter compensation roller according to its own tension and cooperate with different roller surface radius positions, so that path compensation and roller diameter compensation work together in the yarn bundle tension adjustment process, reducing the impact of yarn bundle tension fluctuations on the texturing process.

[0054] Example 2

[0055] Please see Figures 1-5 Based on Example 1, this example illustrates the implementation method of adjusting the tension of the filament bundle by cooperating the lifting mechanism 17 and the diameter compensation mechanism 16.

[0056] 1. Parameter settings

[0057] The effective axial length L of the variable diameter compensating roller 21 is 180 mm. The end closer to the compensating roller support plate 19 is designated as the thin end, and the end closer to the compensating roller ball head 28 is designated as the thick end. The radius R1 of the thin end is 22 mm, the radius R2 of the thick end is 42 mm, and the surface variation coefficient λ is 0.45. After processing according to the roller surface radius relationship in Example 1, the roller surface radius of the variable diameter compensating roller 21 at an axial position x of 90 mm is 29.75 mm.

[0058] The narrow end of the variable diameter compensating roller 21 is rotatably connected to the compensating roller support plate 19 via the compensating roller shaft 20, and the thick end abuts against the second protective plate 34 via the compensating roller ball head 28. A rotating bearing is provided between the compensating roller shaft 20 and the compensating roller support plate 19, so that the variable diameter compensating roller 21 can rotate with the movement of the yarn bundle.

[0059] Two push rod slots 25 are formed on the first protective plate 18, with a center-to-center distance of 100mm between the two push rod slots 25. Two push rod hinge supports 22 are respectively set at the bottom of the two push rod slots 25. The lower end of the electric push rod 23 is rotatably connected to the corresponding push rod hinge support 22. The rolling top support 24 is set at the telescopic end of the electric push rod 23 and abuts against the lower part of the compensating roller support plate 19. The effective stroke of each electric push rod 23 is 30mm, and the initial extension is 12mm.

[0060] 2. Initial operating state of the filament bundle

[0061] Polyester filament bundles with a specification of 150D / 48F were selected for testing. The bundle running speed was set to 600m / min, and the target tension range was set to 18cN-22cN. The bundle was introduced through the first bundle guide hole 13, passed sequentially around the lower side of the feed stabilizing guide roller 26, the upper side of the diameter adjustment compensating roller 21, and the lower side of the output stabilizing guide roller 31, and then exited through the second bundle guide hole 15.

[0062] In the initial state, the two electric push rods 23 maintain the same extension amount, the compensating roller support plate 19 is in a horizontal position, and the filament bundle is located at the axial position x of the variable diameter compensating roller 21 at 90mm. The filament bundle tension is recorded using an independent online tension meter on the filament exit side of the second filament bundle guide hole 15, and the initial tension is 20.1cN.

[0063] 3. Adjustment when tension exceeds the target upper limit

[0064] By changing the subsequent winding state, the yarn tension is increased from 20.1 cN to 27.0 cN. One of the electric push rods 23 is controlled to retract by 8 mm, while the other electric push rod 23 maintains its initial extension. The rolling top support 24 retracts with the electric push rod 23, causing the corresponding side of the compensating roller support plate 19 to descend. The variable diameter compensating roller 21 tilts with the compensating roller support plate 19, shortening the yarn winding path by 11.4 mm.

[0065] Under the combined action of the filament tension and the inclined roller surface, the filament moves along the axial direction of the variable diameter compensation roller 21 from a position of x = 90 mm to a position of x = 55 mm, corresponding to a roller surface radius change from 29.75 mm to 26.20 mm. After adjustment for 2.4 s, the filament tension drops back to 21.0 cN.

[0066] 4. Adjustment when tension is less than the target lower limit

[0067] By changing the front-end feeding state, the fiber tension is changed to 14.6 cN. The corresponding electric push rod 23 is extended by 10 mm, and the rolling top support 24 pushes one side of the compensation roller support plate 19 to rise, so that the variable diameter compensation roller 21 changes its tilt state, and the fiber winding path is extended by 13.2 mm.

[0068] The filament bundle moves axially along the variable diameter compensation roller 21 from a position of x = 55 mm to a position of x = 125 mm, corresponding to a roller surface radius change from 26.20 mm to 33.98 mm. After adjustment for 2.7 s, the filament bundle tension becomes 19.8 cN.

[0069] 5. Test Results

[0070] Twenty consecutive tension disturbance tests were conducted, with the yarn tension being greater than 22 cN or less than 18 cN in each test. After the position of the variable diameter compensation roller 21 was changed by the electric push rod 23, and the yarn moved axially along the variable diameter compensation roller 21, the yarn tension stabilized within the range of 18.9 cN-21.6 cN. During the test, the variable diameter compensation roller 21 rotated continuously, the ball head 28 of the compensation roller remained in contact with the second protective plate 34, the rolling top support 24 did not disengage from the compensation roller support plate 19, and the yarn did not deviate from the path formed by the infeed stabilizing guide roller 26, the variable diameter compensation roller 21, and the outfeed stabilizing guide roller 31.

[0071] Example 3

[0072] Please see Figures 1-5 Based on Examples 1 and 2, this example illustrates how the flywheel mechanism 4 regulates the vibration of the device during operation.

[0073] 1. Running parameter settings

[0074] The pressure sensor 2 has a range of 0N-500N and a sampling frequency of 100Hz. The flywheel mechanism 4 has a diameter of 160mm and a mass of 3.5kg. The motor 5 has a speed range of 600r / min-1200r / min. The load fluctuation amplitude of 8N at the support leg 33 is set as the starting threshold of the motor 5.

[0075] 2. Vibration adjustment process

[0076] During operation, pressure sensor 2 collects load fluctuation signals at support leg 33. When the load fluctuation amplitude is greater than 8N, motor 5 starts and drives flywheel mechanism 4 to rotate; when the load fluctuation amplitude increases, the speed of motor 5 is increased; when the load fluctuation amplitude decreases, the speed of motor 5 is decreased.

[0077] After the flywheel mechanism 4 rotates, it uses rotational inertia to adjust the vibration of the support top plate 9 and the support bottom plate 1. The first wire bundle guide hole 13 and the second wire bundle guide hole 15 constrain the entry and exit positions of the wire bundle, reducing the lateral displacement of the wire bundle caused by the vibration of the support.

[0078] 3. Test Results

[0079] Before the flywheel mechanism 4 was started, the vibration amplitude of the support top plate 9 was 1.8 mm; after the flywheel mechanism 4 rotated at 900 r / min, the vibration amplitude dropped to 0.7 mm, and the load fluctuation amplitude at the support leg 33 dropped from 12.6 N to 5.4 N. After running continuously for 30 minutes, the yarn bundle did not detach from the infeed stabilizing guide roller 26, the diameter compensation roller 21, and the outfeed stabilizing guide roller 31.

[0080] The working principle of this invention is as follows:

[0081] The filament bundle is introduced through the first filament bundle guide hole 13 on the first filament bundle guide plate 12, and then passes sequentially around the lower side of the infeed stabilizing guide roller 26, the upper side of the variable diameter compensation roller 21, and the lower side of the outfeed stabilizing guide roller 31, and is then led out through the second filament bundle guide hole 15 on the second filament bundle guide plate 14 to form a continuous filament bundle conveying path.

[0082] During the operation of the filament bundle, the telescopic end of the electric push rod 23 acts on the compensating roller support plate 19 through the rolling top support 24, causing the compensating roller support plate 19 and one end of the variable diameter compensating roller 21 to rise or fall, thereby changing the wrapping position and conveying path length of the filament bundle when it passes through the variable diameter compensating roller 21. When the tension of the filament bundle changes, the filament bundle slides along the axial direction of the variable diameter compensating roller 21 under the action of tension and moves to the roller surface diameter position corresponding to the current tension state. The tension of the filament bundle is compensated by the combined change of the roller surface diameter and the wrapping path.

[0083] When the device vibrates during operation, the pressure sensor 2, located at the lower end of the support leg 33, detects the dynamic load changes at the support position and controls the motor 5 to operate based on the detection signal. The motor 5 drives the flywheel mechanism 4 to rotate, and the rotational inertia of the flywheel mechanism 4 is used to adjust the vibration state of the support. The first filament guide hole 13 and the second filament guide hole 15 respectively constrain the entry and exit positions of the filaments to limit excessive lateral displacement of the filaments and reduce the proximity or compression of adjacent filaments.

[0084] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

Pass the filament bundle through the first filament bundle guide hole (13), so that the filament bundle passes in sequence around the lower side of the infeed stabilizing guide roller (26), the upper side of the variable diameter compensation roller (21) and the lower side of the outfeed stabilizing guide roller (31), and then is led out through the second filament bundle guide hole (15); S2. Control the extension and retraction of the electric push rod (23), and drive the compensation roller support plate (19) to rise or fall through the rolling top support (24), so that the variable diameter compensation roller (21) changes the length of the winding path of the filament bundle; S3. The filament bundle moves along the axial direction of the variable diameter compensation roller (21) according to its tension, and the wrapping path of the filament bundle is changed by the roller surface radius of the variable diameter compensation roller (21) at different axial positions. S4. The load fluctuation signal at the outrigger (33) is collected by the pressure sensor (2), and the motor (5) is controlled to run according to the load fluctuation signal. The motor (5) drives the flywheel mechanism (4) to rotate.
