Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a dynamic tension-adjusting worm transmission mechanism of a thread-moving reduction box. Background Art

[0002] The yarn transfer reducer is a key component widely used in textile machinery. Its primary function is to decelerate the input rotational power and transmit it to the output shaft through a specific transmission mechanism, thereby driving the precise movement of the textile thread. In the textile process, controlling the thread tension is crucial, directly impacting textile quality and production efficiency. Traditional yarn transfer reducers often use simple gear or belt transmissions. These systems, over time, can easily lead to a decrease in transmission accuracy due to wear and increased backlash, which in turn affects thread tension control.

[0003] Furthermore, traditional yarn reducers have limited adjustment capabilities when facing dynamically changing loads, making it difficult to accurately adjust yarn tension in real time. This can lead to problems such as yarn loosening or breakage during the weaving process, which not only affects textile quality but also increases production costs and maintenance difficulties.

[0004] To address the above issues, the present invention proposes a dynamic tension-adjustable worm gear transmission mechanism for a wire-moving speed reducer. This mechanism effectively reduces input power through the use of a worm gear transmission, and improves transmission accuracy and tension control stability through the use of specific compensation and tension-adjusting components. Summary of the Invention

[0008] An output component is connected to the output shaft for precisely pushing, pulling or lateral movement of the textile thread.

[0009] The tension adjustment component is arranged on the output component and is used to adjust the dynamic tension generated when the output component is working.

[0010] Preferably, the transmission assembly includes a worm wheel fixedly mounted on the output shaft, and a worm mounted on the input shaft. The worm is a hollow structure. The worm wheel and the worm are meshed with each other to form a worm transmission mechanism with a large transmission ratio and stable transmission performance. A compensation assembly is also provided between the worm and the input shaft. The hollow worm is conducive to the installation of the internal compensation assembly. A stepped groove for mounting the worm is provided on the shaft body of the input shaft.

[0011] Preferably, the compensation component includes a rectangular groove opened on the stepped groove, a paddle is slidably connected in the rectangular groove, and a compensation spring is arranged between the paddle and the rectangular groove to provide elastic force for resetting the paddle, and the inner wall of the worm is provided with a travel groove for the paddle to move. When a gap is generated between the worm and the worm wheel due to wear, the compensation spring pushes the paddle to move in the travel groove, thereby making up for the gap and ensuring the stability and accuracy of the transmission.

[0012] Preferably, the number of the compensation components is five, and the five compensation components are arranged in a circular array between the input shaft and the worm to provide compensation force in a uniformly distributed manner, and ball bearings are provided on the shaft body of the input shaft at both ends of the worm to reduce friction between the input shaft and the worm.

[0013] Preferably, the output assembly includes a guide screw fixedly connected to the output shaft through a coupling, and a moving screw is threadedly connected to the rod body of the guide screw. When the output shaft rotates, the guide screw is driven to rotate through the coupling, and then the moving screw is driven to move on the guide screw. This design realizes the precise push-pull or lateral movement of the textile thread. A connecting frame is fixedly connected to the outer side of the shell, and the other end of the guide screw is rotatably connected to the inner wall of the connecting frame. The connecting frame provides stable support for the guide screw and the moving screw. The guide screw is arranged inside the connecting frame, and a limiting assembly is provided between the connecting frame and the moving screw.

[0014] Preferably, the limiting assembly includes a slide groove opened on the inner side of the connecting frame, the inner wall of the slide groove is slidably connected to the limiting slider, and the limiting slider is fixedly connected to the lower end of the screw rod by a bolt, thereby realizing the limitation of the screw rod.

[0015] Preferably, the tension adjustment assembly includes a plug-in slot provided at the upper end of the screw-moving rod, a wire-moving ring is inserted into the inner wall of the plug-in slot, an adjusting spring is provided between the wire-moving ring and the plug-in slot, for providing tension adjustment for the textile thread, a gasket is provided at the lower end of the adjusting spring, an adjusting ring is threadedly connected to the surface of the screw-moving rod, and an arc-shaped groove connected to the plug-in slot is provided on the rod body of the screw-moving rod corresponding to the adjusting ring, a connecting rod connected to the gasket is fixedly installed on the upper end of the adjusting ring, and the height of the gasket can be adjusted by rotating the adjusting ring, thereby adjusting the elastic force of the adjusting spring, which is convenient for adjustment according to the characteristics of different textile threads or the tightness of yarn bobbins from different manufacturers.

[0016] Preferably, the shell includes an upper shell and a lower shell, and the upper shell and the lower shell are fixedly connected by bolts, and the connecting frame is fixedly installed on the side of the upper shell.

[0017] Preferably, the inner wall of the plug-in slot is provided with three snap-in grooves, and the handle of the wire moving ring is provided with three snap-in blocks adapted to the snap-in grooves. The setting of the snap-in grooves and the snap-in blocks prevents the wire moving ring from rotating in the plug-in slot, thereby ensuring the stability and reliability of the tension adjustment assembly.

[0018] Preferably, a mounting column is fixedly installed on the inner wall of the rectangular groove, the compensation spring is sleeved on the mounting column, and a through hole for inserting the mounting column is opened on the surface of the paddle. The setting of the mounting column limits the radial movement of the compensation spring and the paddle, thereby improving the stability of the structure.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention provides a compensating assembly on the transmission assembly, which increases the torque of power transmission while utilizing the worm to drive the worm wheel for deceleration. The compensating assembly can also compensate for the wear gap of the worm wheel and worm after long-term operation. When the wear gap is too large, the paddle of the compensating assembly, under the action of the compensating spring, forces the worm wheel and worm to fit tightly together during initial startup. When the rotation speed reaches a certain speed, the collision between the worm wheel and the worm is reduced under the action of centrifugal force. Therefore, the compensating assembly compensates for the wear gap between the worm wheel and the worm in the initial stage, avoiding direct hard collision between the worm wheel and the worm during initial startup.

[0021] 2. The present invention provides a tension adjustment component on the output component, and the wire moving ring follows the guide wire rod to accurately push and pull the textile wire. When pushing and pulling the textile wire, since the textile wire is relatively soft and has a certain weight, the middle section of the textile wire will naturally sag, resulting in insufficient traction force of the textile wire, affecting subsequent weaving or winding operations. By providing a tension adjustment component on the wire moving rod, the traction force of the wire can be adjusted, so that the textile wire always maintains a certain tension when pushing and pulling the wire, avoiding excessive relaxation of the textile wire and improving the quality of subsequent weaving or winding.

[0033] 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.

[0034] See also Figures 1 to 9 The present invention provides a technical solution: a dynamic tension adjustment worm gear transmission mechanism of a wire moving reduction box, comprising a housing 1, an input shaft 2, and an output shaft 3, wherein the input shaft 2 and the output shaft 3 are perpendicularly arranged in the housing 1, and the housing 1 comprises an upper housing 101 and a lower housing 102, and the upper housing 101 and the lower housing 102 are fixedly connected by bolts, and further comprising:

[0035] The transmission assembly 4 is disposed in the housing 1 and is used to transmit the power of the input shaft 2 to the output shaft 3 and achieve a deceleration effect;

[0036] Specifically, such as Figure 2 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9 As shown, the transmission assembly 4 includes a worm wheel 401 fixedly mounted on the output shaft 3, and a worm 402 sleeved on the input shaft 2. The worm 402 is a hollow structure. The worm wheel 401 and the worm 402 are meshed with each other to form a worm transmission mechanism. A compensation assembly 403 is also provided between the worm 402 and the input shaft 2. The hollow setting of the worm 402 facilitates the installation of the internal compensation assembly 403, and a stepped groove 404 for sleeved worm 402 is provided on the shaft body of the input shaft 2.

[0037] Further, such as Figure 2 、 Figure 5 and Figure 9As shown, the compensation component 403 includes a rectangular groove 4031 formed on the stepped groove 404, a paddle 4032 is slidably connected in the rectangular groove 4031, and a compensation spring 4033 is provided between the paddle 4032 and the rectangular groove 4031 to provide elastic force for the paddle 4032 to return to its original position. A travel groove 4034 is provided on the inner wall of the worm 402 for the paddle 4032 to move. When a gap is generated between the worm 402 and the worm wheel 401 due to wear, the compensation spring 4033 is provided. 33 pushes the paddle 4032 to move in the travel groove 4034, thereby compensating for the gap and ensuring the stability and accuracy of the transmission. A mounting post 4035 is fixedly installed on the inner wall of the rectangular groove 4031, and the compensation spring 4033 is sleeved on the mounting post 4035. A through hole for inserting the mounting post 4035 is opened on the surface of the paddle 4032. The setting of the mounting post 4035 limits the radial movement of the compensation spring 4033 and the paddle 4032, thereby improving the stability of the structure.

[0038] Specifically, such as Figure 9 As shown, there are five compensation components 403, which are arranged in a circular array between the input shaft 2 and the worm 402 to provide compensation force in a uniformly distributed manner, and ball bearings 405 are provided on the shaft body of the input shaft 2 at both ends of the worm 402 to reduce friction between the input shaft 2 and the worm 402.

[0039] It should be noted that this mechanism uses the worm 402 to drive the worm wheel 401 for deceleration driving while increasing the torque of power transmission, and the compensation component 403 can make up for the wear gap between the worm wheel 402 and the worm 401 after long-term operation. When the wear gap is too large, the paddle 4032 of the compensation component 403, under the action of the compensation spring 4033, forces the worm wheel 401 and the worm 402 to fit tightly during the initial startup. When the speed reaches a certain speed, under the action of centrifugal force, the collision between the worm wheel 401 and the worm 402 will be reduced. Therefore, the compensation component 403 plays a role in making up for the wear gap between the worm wheel 401 and the worm 402 in the initial stage, thereby avoiding direct hard collision between the worm wheel 401 and the worm 402 during the initial startup.

[0040] The output component 5 is connected to the output shaft 3 and is used for precisely pushing, pulling or lateral movement of the textile thread.

[0041] Specifically, such as Figure 3As shown, the output component 5 includes a guide screw rod 501 fixedly connected to the output shaft 3 through a coupling, and a moving screw rod 502 is threadedly connected to the rod body of the guide screw rod 501. When the output shaft 3 rotates, the guide screw rod 501 is driven to rotate through the coupling, and then the moving screw rod 502 is driven to move on the guide screw rod 501. This design realizes the precise push-pull or lateral movement of the textile thread. A connecting frame 503 is fixedly connected to the outer side of the upper shell 101. The connecting frame 503 provides stable support for the guide screw rod 501 and the moving screw rod 502. The guide screw rod 501 is arranged inside the connecting frame 503, and the other end of the guide screw rod 501 is rotatably connected to the inner wall of the connecting frame 503, and a limiting component 504 is arranged between the connecting frame 503 and the moving screw rod 502.

[0042] Specifically, such as Figure 3 As shown, the limiting assembly 504 includes a slide groove 5041 opened on the inner side of the connecting frame 503, and the inner wall of the slide groove 5041 is slidably connected to the limiting slider 5042. The limiting slider 5042 is fixedly connected to the lower end of the screw rod 502 by a bolt, thereby limiting the screw rod 502 and preventing the screw rod 502 from axial rotation.

[0043] The tension adjustment component 6 is arranged on the output component 5 and is used to adjust the dynamic tension generated when the output component 5 is working.

[0044] Specifically, such as Figure 6 As shown, the tension adjustment component 6 includes a plug-in slot 601 provided at the upper end of the wire moving rod 502, a wire moving ring 602 is inserted into the inner wall of the plug-in slot 601, three clamping slots 7 are provided on the inner wall of the plug-in slot 601, and three clamping blocks 8 adapted to the clamping slots 7 are provided on the handle of the wire moving ring 602. An adjusting spring 603 is provided between the wire moving ring 602 and the plug-in slot 601 for providing tension adjustment for the textile thread. A gasket 604 is provided at the lower end of the adjusting spring 603. An adjusting ring 605 is threadedly connected to the surface of the screw rod 502, and an arc-shaped groove 606 connected to the plug-in groove 601 is provided on the rod body of the screw rod 502 corresponding to the adjusting ring 605. A connecting rod 607 connected to the gasket 604 is fixedly installed on the upper end of the adjusting ring 605. By rotating the adjusting ring 605, the height of the gasket 604 can be adjusted, and then the elastic force of the adjusting spring 603 can be adjusted, which is convenient for adjustment according to the characteristics of different textile silk threads or the tightness of yarn bobbins from different manufacturers.

[0045] It should be noted that, by arranging the tension adjustment component 6 on the output component 5, the wire moving ring 602 moves along with the guide wire rod 501, and the textile wire is pushed and pulled accurately. When the textile wire is pushed and pulled, since the textile wire is relatively soft and has a certain weight of its own, the middle section of the textile wire will naturally sag, resulting in insufficient traction force of the textile wire, affecting subsequent weaving or winding operations. By arranging the tension adjustment component 6 on the wire moving rod 502, the traction force of the wire can be adjusted, so that the textile wire always maintains a certain tension when pushing and pulling the wire, avoiding the textile wire from being too loose, and improving the quality of subsequent weaving or winding.

[0046] Working principle: During the weaving process, power is input into the transmission component 4 through the input shaft 2. The input shaft 2 drives the worm 402 to rotate, and the worm 402 engages with the worm wheel 401 to achieve reduced power transmission. The hollow structure of the worm 402 provides space for the installation of the compensation component 403. Under the action of the compensation spring 4033, the paddle 4032 of the compensation component 403 is always close to the inner wall of the worm 402.

[0047] When a wear gap is generated between the worm 402 and the worm wheel 401 due to long-term operation, the compensation spring 4033 pushes the paddle 4032 to move in the travel groove 4034 to fill the gap and avoid a hard collision between the worm wheel 401 and the worm 402 due to the gap during startup. At the same time, the provision of the ball bearing 405 reduces the friction between the input shaft 2 and the worm 402, further improving the stability and durability of the transmission.

[0048] The transmission component 4 transmits the decelerated power to the output shaft 3, thereby driving the guide screw 501 to rotate. The rotation of the guide screw 501 drives the screw rod 502 to move on the guide screw 501, thereby achieving precise pushing, pulling or lateral movement of the textile thread. The limit component 504 ensures the stability of the screw rod 502 during the movement and prevents its axial rotation.

[0049] During the movement of the screw rod 502, the tension adjustment component 6 plays a key role. The screw ring 602 moves with the movement of the screw rod 502 and is at the same time affected by the elastic force of the adjustment spring 603. The elastic force of the adjustment spring 603 can be adjusted by rotating the adjustment ring 605, thereby changing the tension adjustment effect on the textile thread.

[0050] Since the textile thread is relatively soft and has a certain amount of its own weight, it is easy to sag in the middle section during the weaving process, resulting in insufficient traction. The setting of the tension adjustment component 6 can dynamically adjust the traction force of the thread to ensure stable tension during the weaving process. When the thread is loose, by rotating the adjustment ring 605, it drives the adjustment spring 603 to move upward, and then drives the wire moving ring 602 to move upward, support the thread, and increase the tension of the thread; when the thread is too tight, by rotating the adjustment ring 605, it drives the adjustment spring 603 to move downward, and then drives the wire moving ring 602 to move downward, so that the height of the thread is reduced and the tension of the thread is reduced.

[0051] In addition, the arrangement of the snap-in groove 7 and the snap-in block 8 prevents the wire moving ring 602 from rotating in the plug-in groove 601, thereby ensuring the stability and reliability of the tension adjustment assembly 6. The entire mechanism has a compact structure, which is suitable for the tension control requirements of high-precision textile machinery, and significantly improves the quality stability of the weaving or winding process.

[0052] In summary, the dynamic tension adjustment worm transmission mechanism of the wire moving reducer of the present invention realizes effective deceleration and dynamic tension adjustment of the input power by adopting a worm transmission method, a compensation component 403 and a tension adjustment component 6, thereby improving the transmission accuracy and the stability of the tension control, and providing an efficient and reliable transmission mechanism for the textile industry.
