Description

Technical Field

[0001] This invention relates to the field of differential fiber production, and more specifically, to a tensioning mechanism based on differential fiber transport. Background Technology

[0002] In the fiber processing and production process, the stability of the fiber conveying link directly affects the quality of subsequent processing. As the core component of the fiber conveying system, the tensioning mechanism mainly functions to adjust the tension during the fiber conveying process, prevent the fiber from becoming loose, shifted, wrinkled, or broken due to excessive stretching, and ensure that the fiber can be conveyed smoothly and orderly to the next processing step.

[0003] Existing fiber conveying tensioning mechanisms suffer from two major defects in practical applications, failing to meet the conveying needs of diverse fibers. Specifically: Firstly, regarding tension adjustment, existing mechanisms mostly employ fixed guide roller structures, lacking tension adjustment functionality. They cannot adjust the position of the guide rollers to change the tension based on different types and specifications of fibers, as well as variations in conveying conditions. This leads to problems such as slack shifting, entanglement, and jamming during fiber conveying, or even tensile breakage due to excessive tension, severely impacting conveying efficiency and product quality. Secondly, regarding vibration buffering, fiber conveying is subject to vibrations caused by equipment operation and material flow fluctuations. Existing tensioning mechanisms lack any vibration buffering structure, allowing vibrations to be directly transmitted to the guide rollers. This not only causes severe fluctuations in the tension of the guide rollers on the fibers, disrupting the stability of fiber conveying, but also accelerates the wear of mechanism components, shortening the equipment's lifespan.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a tensioning mechanism based on differential fiber delivery and its usage method. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a tensioning mechanism based on differential fiber delivery and its usage method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tensioning mechanism based on differential fiber conveying, comprising a vertically arranged vertical plate, wherein a through groove A extending in the vertical direction is provided at the diagonal positions on the upper and lower sides of the vertical plate, and a lifting platform is slidably fitted in each through groove A, and the lifting platform can slide stably up and down in a straight line along the extension direction of the through groove A.

[0007] Each of the lifting platforms is rotatably connected to a guide roller via a bearing A. The guide roller can rotate flexibly around the axis of bearing A and is used to receive and guide the fiber conveying.

[0008] A reciprocating assembly is installed on the back of the vertical plate. This reciprocating assembly is used to synchronously drive the two lifting platforms to move up and down, so as to realize the tension adjustment during the fiber conveying process. Buffering components are installed between the two transmission parts of the reciprocating assembly and the corresponding lifting platforms. The buffering components are used to buffer the vibration of the guide roller during the material conveying process and ensure the stable tension of the guide roller on the fiber.

[0009] Preferably, guide rails A for sliding slider A are installed on both sides of the inner side of the through groove A, and the lifting platform is fixed between the two sliders A.

[0010] Preferably, the reciprocating assembly includes bearing seats installed on the upper and lower sides of the back of the vertical plate and located on the same vertical line, and bearings B are installed inside the bearing seats. A screw A with opposite threads on the upper and lower sides and symmetrical about the middle part is connected to the inner ring of the bearings B. The upper and lower sides of the outer wall of the screw A are threaded with rod sleeves. The side ends of the rod sleeves are connected to the buffer assembly through crossbars. A motor that drives the screw A to rotate is installed on the bearing seat.

[0011] Preferably, the buffer assembly includes a connecting shell connected to the crossbar. Guide rails B for sliding sliders B are installed on both sides of the inner side of the connecting shell. A connecting plate A is fixedly connected between the sliders B. Multiple springs are installed between the bottom of the connecting plate A and the bottom wall of the connecting shell. A damper is installed between the top of the connecting plate A and the top wall of the connecting shell. The top two sides of the connecting plate A are connected to the lifting platform through vertical rods. A through slot B for the vertical rods to pass through is provided on the top of the connecting shell.

[0012] Preferably, the bearing seat is detachably connected to the back of the vertical plate by screws, a connecting block is fixedly connected to the top of the vertical rod, a connecting slot seat is fixedly connected to the back of the lifting platform, a top block is fixedly connected to the top of the connecting block, and a through groove C is provided on the connecting slot seat for the top block to pass through.

[0013] Preferably, the top of the connecting slot seat is equipped with guide rails C on both sides of the through groove C for sliding slider C. The top of each slider C is fixedly connected to a movable plate. The top block has grooves on both sides. The movable plate and the grooves have protrusions fixedly connected to the opposite surfaces of the grooves, which can be inserted into the grooves. The top of the connecting slot seat is also fixedly connected to both sides of the connecting plate. The connecting plate B is internally threaded with a screw B. The head of the screw B is rotatably connected to the movable plate through a bearing C, and the end is fixedly connected to a handle for easy rotation.

[0014] Preferably, a movable platform is fixedly connected to the bottom of the vertical plate, and each of the four corners of the bottom of the movable platform is equipped with a universal wheel with locking function.

[0015] Preferably, the height of the vertical plate is adjustable.

[0016] Preferably, the top of the mobile platform is fixedly connected to two sliding rods on both sides, and the vertical plate is fixedly connected to two sliding sleeves that slide along the sliding rods on both sides. The surface of the sliding rods is provided with multiple screw holes arranged in a vertical array, and the surface of the sliding sleeves is provided with through holes. The height of the vertical plate is fixed by inserting large screws through the through holes into the screw holes of corresponding heights.

[0017] The above-mentioned method of using the tensioning mechanism based on differential fiber delivery includes the following steps:

[0018] Step 1: Loosen the locking devices of the four corner casters with locking function at the bottom of the moving platform, push the entire tensioning mechanism to move it to the corresponding installation position of the fiber conveying system, adjust the placement angle of the mechanism so that the position of the two guide rollers is aligned with the fiber conveying path, and then lock the casters to fix the mechanism in the current position to prevent displacement during operation.

[0019] Step 2: Adjust the height of the vertical plate according to the height of the fiber conveyor line and the docking requirements of the processing equipment. First, loosen the large screw that passes through the through hole of the sliding sleeve and the screw hole of the sliding rod to release the fixed limit of the sliding sleeve and the sliding rod. Push the vertical plate up and down to drive the sliding sleeve to slide along the sliding rod at the top of the moving table until the vertical plate and guide roller are adjusted to the appropriate height. Then, screw the large screw through the through hole into the screw hole of the corresponding height and tighten it to complete the fixation of the vertical plate height.

[0020] Step 3: Align the bearing housing of the reciprocating assembly with the installation position on the back of the vertical plate and secure it firmly with screws. Ensure that the bearing housing, screw A, motor and other components are in accurate positions. Then, insert the connecting block at the top of the vertical rod on the buffer assembly into the connecting slot on the back of the lifting platform, so that the top block completely passes through the through slot C. Turn the handle forward to drive the screw B to rotate around the bearing C, and push the moving plate along the guide rail C toward the top block until the protrusion is completely inserted into the grooves on both sides of the top block. This completes the fixing of the buffer assembly and the lifting platform. Then, align the fiber conveying path with the surface of the two guide rollers.

[0021] Step 4: By controlling the forward and reverse rotation of the motor, the relative distance between the two guide rollers is adjusted to dynamically regulate the fiber tension.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This invention changes the tension during fiber conveying by adjusting the relative distance between two guide rollers. It can flexibly adjust to a suitable tension according to the different types and specifications of fibers and the changes in conveying conditions, effectively avoiding problems such as fiber slack and deviation, entanglement and jamming, or excessive stretching and breakage, and ensuring conveying effect and product quality.

[0024] 2. The present invention can effectively absorb and buffer the vibration through the buffer component, avoiding the vibration from being directly transmitted to the reciprocating component and the vertical plate. This ensures the stable tension of the fiber by the guide roller, prevents drastic fluctuations in tension, reduces the wear of the mechanical parts by vibration, extends the service life of the equipment, and ultimately achieves the smooth and stable conveying of different fibers.

[0025] 3. In this invention, the reciprocating component and the buffer component can be detached from the adjustment mechanism. The reciprocating component includes easily worn transmission components such as motor, screw A, and bearing B, and the buffer component includes easily aged buffer components such as spring and damper. The detachable design allows the damaged component to be directly removed and replaced or repaired, reducing maintenance difficulty and downtime.

[0026] 4. The present invention can flexibly move the entire tensioning mechanism in multiple directions by means of casters with locking function, which makes it easy to adjust the installation position and placement angle of the mechanism according to the site layout of the fiber conveying system and the equipment debugging requirements, without the need for external lifting or handling tools, reducing the difficulty of moving the mechanism and handling costs, and improving the installation flexibility and adaptability of the mechanism.

[0027] 5. The height of the vertical plate in this invention can be adjusted. The overall height of the vertical plate and guide roller can be flexibly adjusted according to the height of different fiber conveying lines and the docking requirements of different processing equipment. This allows the guide roller to accurately match the fiber conveying path, avoiding fiber deviation and abnormal tension caused by mismatched conveying heights, and further adapting to the diverse conveying needs of different fibers.

[0038] Example 1

[0039] like Figure 1 , Figure 2 as well as Figure 6 As shown, the present invention provides a tensioning mechanism based on differential fiber conveying, including a vertically arranged vertical plate 1. The vertical plate 1 has through slots A101 extending vertically at diagonal positions on both the upper and lower sides. Each through slot A101 is slidably fitted with a lifting platform 2, and the lifting platform 2 can slide stably up and down in a straight line along the extension direction of the through slot A101. The inside of the through slot A101 is equipped with guide rails A7 for sliding sliders A8. The lifting platform 2 is fixed between the two sliders A8.

[0040] Each lifting platform 2 is rotatably connected to a guide roller 4 via a bearing A3. The guide roller 4 can rotate flexibly around the axis of the bearing A3 to receive and guide the fiber conveying.

[0041] A reciprocating assembly 5 is installed on the back of the vertical plate 1. The reciprocating assembly 5 is used to synchronously drive the two lifting platforms 2 to move up and down to achieve tension adjustment during fiber conveying. Buffering assemblies 6 are installed between the two transmission parts of the reciprocating assembly 5 and the corresponding lifting platforms 2. Buffering assemblies 6 are used to buffer the vibration of the guide roller 4 during the conveying process and ensure the stable tension of the guide roller 4 on the fiber.

[0042] When the tensioning mechanism based on differential fiber conveying of this invention is working, it is first installed at the corresponding position in the fiber conveying system, so that the fiber conveying path is in contact with the surface of the two guide rollers 4. The guide rollers 4 are rotatably connected to the lifting platform 2 through the bearing A3, and can flexibly rotate around the axis of the bearing A3, thereby smoothly receiving and guiding the fiber conveying. Guide rails A7 are installed in the through grooves A101 at the diagonal positions on the upper and lower sides of the vertical plate 1. The lifting platform 2 is fixed between two sliders A8. The sliders A8 and the guide rails A7 slide in cooperation, providing stable guidance for the movement of the lifting platform 2, ensuring that the lifting platform 2 can slide smoothly up and down in a straight line along the extension direction of the through grooves A101, thereby ensuring the stability of the guide rollers 4 during movement. To solve the problem that the existing mechanism cannot adjust the tension, the reciprocating assembly 5 installed on the back of the vertical plate 1 is activated. The two transmission parts of the reciprocating assembly 5 synchronously drive the corresponding side of the lifting platform 2 to move up and down (the two lifting platforms 2 move up and down to the upper and lower sides or to the middle at the same time). The lifting platform 2 drives the guide rollers 4 to move up and down. The guide rollers 4 are raised and lowered synchronously. By adjusting the relative distance between the two guide rollers 4, the tension during fiber conveying can be changed. The tension can be flexibly adjusted to a suitable level according to the different types and specifications of fibers and the changes in conveying conditions, effectively avoiding problems such as fiber slack, entanglement, jamming, or excessive stretching and breakage, ensuring conveying effect and product quality. To solve the problem that the existing mechanism cannot buffer vibration, the buffer component 6 installed between the transmission part of the reciprocating component 5 and the lifting platform 2 plays a buffering role. When vibration is generated during fiber conveying due to equipment operation vibration and material flow fluctuation, the vibration will be transmitted to the lifting platform 2 through the guide rollers 4. The buffer component 6 can effectively absorb and buffer the vibration, preventing the vibration from being directly transmitted to the reciprocating component 5 and the vertical plate 1. This not only ensures the stable tension of the fiber by the guide rollers 4 and prevents drastic tension fluctuations, but also reduces the wear of the mechanism parts by vibration, extends the service life of the equipment, and ultimately achieves smooth and stable conveying of different fibers.

[0043] Example 2

[0044] like Figure 1 , Figure 2 , Figure 7 as well as Figure 8As shown in the figure, this embodiment provides the specific structure of the reciprocating assembly 5 and the buffer assembly 6 in Embodiment 1: The reciprocating assembly 5 includes bearing seats 501 installed on the upper and lower sides of the back of the vertical plate 1 and located on the same vertical line. Bearings B502 are installed inside each bearing seat 501. A screw A503 with opposite threads on the upper and lower sides and symmetrical about the middle portion is connected to the inner ring of each bearing B502. Rod sleeves 504 are threaded to the upper and lower sides of the outer wall of the screw A503. The side ends of the rod sleeves 504 are connected to the buffer assembly 6 via crossbars 505. A mechanism for driving the screw A503 to rotate is installed on the bearing seat 501. The motor 506 and the buffer assembly 6 include a connecting shell 601 connected to the crossbar 505. The inner sides of the connecting shell 601 are equipped with guide rails B602 for sliding sliders B603. A connecting plate A607 is fixedly connected between the sliders B603. Multiple springs 604 are installed between the bottom of the connecting plate A607 and the inner bottom wall of the connecting shell 601. A damper 605 is installed between the top of the connecting plate A607 and the inner top wall of the connecting shell 601. The top two sides of the connecting plate A607 are connected to the lifting platform 2 through vertical rods 606. The top of the connecting shell 601 has a through groove B6011 for the vertical rods 606 to pass through.

[0045] In use, the motor 506 of the reciprocating assembly 5 on the back of the vertical plate 1 is started. The motor 506 drives the screw A503, which is installed inside the bearing B502 inside the bearing seat 501, to rotate. Since the threads on the upper and lower sides of the screw A503 are opposite and symmetrical about the middle part, its rotation will drive the sleeve 504 connected to the upper and lower threads on the outer side wall to move synchronously to the upper and lower sides or to the middle part (depending on the forward or reverse rotation of the motor 506). The sleeve 504 drives the buffer assembly 6 and the lifting platform 2 connected to it to move synchronously through the crossbar 505. The lifting platform 2 then drives the guide roller 4 to rise and fall. By adjusting the relative distance between the two guide rollers 4, the tension during the fiber conveying process can be flexibly changed. It can adapt to different types and specifications of fibers and changes in conveying conditions, effectively avoiding problems such as fiber loosening and deviation, entanglement and jamming, or excessive stretching and breakage, ensuring the conveying effect and product quality.

[0046] When vibrations occur during fiber conveying due to equipment operation and material flow fluctuations, the vibrations are transmitted to the lifting platform 2 via the guide roller 4. The lifting platform 2 moves the connecting plate A607 via the vertical rod 606. The sliders B603 on both sides of the connecting plate A607 slide along the guide rails B602 inside the connecting shell 601, guiding and limiting the movement of the connecting plate A607. At the same time, the spring 604 between the bottom of the connecting plate A607 and the inner bottom wall of the connecting shell 601 can elastically extend and retract to absorb the vibration impact. The top of the connecting plate A607 and the connecting shell... The damper 605 between the inner top walls of 601 can attenuate the vibration amplitude and suppress the resonance of the spring 604. The vertical rod 606 moves flexibly along the through groove B6011 at the top of the connecting shell 601 to ensure a smooth buffering process. Through the cooperation of the spring 604 and the damper 605, the vibration is effectively buffered, and the vibration is prevented from being transmitted to the reciprocating assembly 5 and the vertical plate 1. This ensures the stable tension of the guide roller 4 on the fiber, prevents violent tension fluctuations, reduces the wear of the mechanical parts by vibration, extends the service life of the equipment, and ultimately achieves the smooth and stable conveying of different fibers.

[0047] Example 3

[0048] like Figures 1-4 as well as Figure 7 As shown, this embodiment is an improvement on embodiment 2: the reciprocating assembly 5 and the buffer assembly 6 can be detached from the adjustment mechanism. The reciprocating assembly 5 includes easily worn transmission components such as motor 506, screw A503, and bearing B502, while the buffer assembly 6 includes easily aged buffer components such as spring 604 and damper 605. The detachable design allows for direct removal and replacement or repair of damaged components, reducing maintenance difficulty and downtime. The specific detachable structure is as follows:

[0049] The bearing seat 501 is detachably connected to the back of the vertical plate 1 by screws. The top of the vertical rod 606 is fixedly connected to the connecting block 9. The back of the lifting platform 2 is fixedly connected to the connecting slot seat 10. The top of the connecting block 9 is fixedly connected to the top block 11. The connecting slot seat 10 has a through groove C1001 for the top block 11 to pass through. The top of the connecting slot seat 10 is equipped with guide rails C12 on both sides of the through groove C1001 for the slider C13 to slide. The top of the slider C13 is fixedly connected to the top of the slider C13. The top of the top block 11 has grooves 1101 on both sides. The opposite surfaces of the moving plate 14 and the grooves 1101 are fixedly connected to the protrusions 15 that can be inserted into the grooves 1101. The top of the connecting slot seat 10 is also fixedly connected to the connecting plate B16 on both sides. The connecting plate B16 is internally threaded with a screw B17. The head of the screw B17 is rotatably connected to the moving plate 14 through the bearing C18. The end is fixedly connected to a handle 19 for easy rotation.

[0050] During disassembly, first disconnect the connection between the buffer assembly 6 and the lifting platform 2. Then, rotate the handles 19 on the connecting plates B16 on both sides of the top of the connecting slot seat 10 in the opposite direction. The handles 19 will drive the screw B17 to rotate around the bearing C18. Since the screw B17 is threadedly connected to the connecting plate B16, its rotation will pull the movable plate 14, which is connected to it, to slide along the guide rail C12 away from the through groove C1001. The movable plate 14 will drive the bottom slider C13 to slide synchronously until the protrusions 15 on the movable plate 14 are completely disengaged from the grooves 1101 on both sides of the top block 11. Release the limit on the top block 11, then pull the lifting platform 2 away from the connecting block 9 (or the two buffer components 6 can be moved towards the middle by the motor 506, so that the connecting block 9 is away from the lifting platform 2), so that the connecting block 9 and the top block 11 at the top of the vertical rod 606 are pulled out from the through slot C1001 of the connecting slot seat 10, and at the same time, the connecting block 9 is pulled out from the connecting slot seat 10. Then unscrew the screws that fix the bearing seat 501 and the back of the vertical plate 1, release the fixed limit on the bearing seat 501 and the vertical plate 1, and pull the reciprocating assembly 5 as a whole. This allows the reciprocating assembly 5, including components such as motor 506 and screw A503, and the buffer assembly 6, which has been separated from the lifting platform 2, to be removed from the adjusting mechanism for easy maintenance or replacement. During installation, first align the bearing seat 501 of the reciprocating assembly 5 with the installation position on the back of the vertical plate 1, and secure it firmly with screws, ensuring that the screw A503, motor 506, and other components are accurately positioned. Then, insert the connecting block 9 at the top of the vertical rod 606 on the buffer assembly 6 into the connecting slot 10 (by pulling the lifting platform 2 or driving the two buffer assemblies 6 by the motor 506). (Move up and down to achieve this). After insertion, the top block 11 will also completely pass through the through slot C1001. Then, rotate the handle 19 in the forward direction to drive the screw B17 to rotate, pushing the moving plate 14 to slide along the guide rail C12 towards the top block 11 until the protrusion 15 on the moving plate 14 is completely inserted into the grooves 1101 on both sides of the top block 11 (at this time, the handle 19 is in close contact with the surface of the connecting plate B16). The top block 11 is limited and fixed to ensure that the buffer assembly 6 is firmly connected to the lifting platform 2. The installation of the reciprocating assembly 5 and the buffer assembly 6 can then be completed.

[0051] Example 4

[0052] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, this embodiment is an improvement on embodiment 1: a movable platform 20 is fixedly connected to the bottom of the vertical plate 1, and four corners of the bottom of the movable platform 20 are equipped with universal wheels 21 with locking function. The universal wheels 21 with locking function can flexibly drive the entire tensioning mechanism to move in multiple directions, which makes it easy to adjust the installation position and placement angle of the mechanism according to the on-site layout of the fiber conveying system and the equipment debugging requirements. There is no need to use external lifting or handling tools, which reduces the difficulty of moving the mechanism and the handling cost, and improves the installation flexibility and adaptability of the mechanism.

[0053] Furthermore, the height of the vertical plate 1 can be adjusted. The overall height of the vertical plate 1 and the guide roller 4 can be flexibly adjusted according to the height of different fiber conveying lines and the docking requirements of different processing equipment. This allows the guide roller 4 to accurately adapt to the fiber conveying path, avoiding fiber deviation and abnormal tension caused by mismatched conveying heights. This further adapts to the diverse conveying needs of different fibers. The following is the specific adjustable structure: The top of the moving table 20 is fixedly connected to two sliding rods 22 on both sides. The two sides of the vertical plate 1 are fixedly connected to sliding sleeves 23 that slide along the sliding rods 22. The surface of the sliding rods 22 has multiple screw holes 2201 arranged in a vertical array. The surface of the sliding sleeves 23 has through holes 2301. The height of the vertical plate 1 is fixed by inserting large screws 24 through the through holes 2301 into the screw holes 2201 of the corresponding height.

[0054] First, loosen the large screw 24 that passes through the through hole 2301 of the sliding sleeve 23 and the screw hole 2201 of the sliding rod 22 to release the fixed limit of the sliding sleeve 23 and the sliding rod 22. Since the sliding sleeves 23 on both sides of the vertical plate 1 and the sliding rods 22 on both sides of the top of the moving table 20 slide together, the vertical plate 1 can be pushed up and down to drive the sliding sleeves 23 to slide along the sliding rods 22 until the vertical plate 1 and the guide roller 4 are adjusted to the position that matches the height of the fiber conveyor line and the docking requirements of the processing equipment. Then, pass the large screw 24 through the through hole 2301 of the sliding sleeve 23 and screw it into the screw hole 2201 of the corresponding height of the sliding rod 22. Tighten the large screw 24 to fix the height of the vertical plate 1 and complete the adjustment.

[0055] The present invention also provides a method for using the above-mentioned tensioning mechanism based on differential fiber delivery:

[0056] Step 1: Loosen the locking devices of the universal wheels 21 with locking function at the four corners of the bottom of the moving table 20, push the entire tensioning mechanism to move it to the corresponding installation position of the fiber conveying system, adjust the placement angle of the mechanism so that the positions of the two guide rollers 4 are aligned with the fiber conveying path, and then lock the universal wheels 21 to fix the mechanism in the current position to prevent displacement during operation.

[0057] Step 2: Adjust the height of the vertical plate 1 according to the height of the fiber conveyor line and the docking requirements of the processing equipment. First, loosen the large screw 24 that passes through the through hole 2301 of the sliding sleeve 23 and the screw hole 2201 of the sliding rod 22 to release the fixed limit of the sliding sleeve 23 and the sliding rod 22. Push the vertical plate 1 up and down to drive the sliding sleeve 23 to slide along the sliding rod 22 at the top of the moving table 20 until the vertical plate 1 and the guide roller 4 are adjusted to a suitable height. Then, screw the large screw 24 through the through hole 2301 into the screw hole 2201 of the corresponding height and tighten it to complete the height fixing of the vertical plate 1.

[0058] Step 3: Align the bearing seat 501 of the reciprocating assembly 5 with the installation position on the back of the vertical plate 1, and fix it firmly with screws to ensure that the bearing seat 501, screw A503, motor 506 and other components are in accurate position. Then insert the connecting block 9 at the top of the vertical rod 606 on the buffer assembly 6 into the connecting slot 10 on the back of the lifting platform 2, so that the top block 11 completely passes through the through slot C1001. Rotate the handle 19 in the forward direction to drive the screw B17 to rotate around the bearing C18, and push the moving plate 14 along the guide rail C12 towards the top block 11 until the protrusion 15 is completely inserted into the grooves 1101 on both sides of the top block 11, thus completing the fixing of the buffer assembly 6 and the lifting platform 2. Then, align the fiber conveying path with the surface of the two guide rollers 4.

[0059] Step 4: By controlling the forward and reverse rotation of motor 506, the relative distance between the two guide rollers 4 is adjusted to dynamically regulate the fiber tension and avoid problems such as fiber slack, shifting, tangling, jamming, or excessive stretching and breakage.

[0060] The tensioning mechanism based on differential fiber delivery and its method of use of the present invention have the following advantages:

[0061] By adjusting the relative distance between the two guide rollers 4, the tension during fiber conveying can be changed. The tension can be flexibly adjusted to a suitable level according to the different types and specifications of fibers and the changes in conveying conditions, effectively avoiding problems such as fiber loosening and shifting, entanglement and jamming, or excessive stretching and breakage, thus ensuring conveying effect and product quality.

[0062] The buffer component 6 can effectively absorb and buffer the vibration, preventing the vibration from being directly transmitted to the reciprocating component 5 and the vertical plate 1. This ensures the stable tension of the fiber by the guide roller 4, prevents drastic fluctuations in tension, reduces the wear of the mechanical parts by vibration, extends the service life of the equipment, and ultimately achieves the smooth and stable conveying of different fibers.

[0063] The reciprocating assembly 5 and the buffer assembly 6 can be removed from the adjustment mechanism. The reciprocating assembly 5 includes easily worn transmission components such as motor 506, screw A503, and bearing B502. The buffer assembly 6 includes easily aged buffer components such as spring 604 and damper 605. The detachable design allows the damaged components to be removed and replaced or repaired directly, reducing maintenance difficulty and downtime.

[0064] The universal wheels 21 with locking function can flexibly drive the entire tensioning mechanism to move in multiple directions, which makes it easy to adjust the installation position and placement angle of the mechanism according to the site layout of the fiber conveying system and the equipment debugging requirements. No external lifting or handling tools are needed, which reduces the difficulty of moving the mechanism and the handling cost, and improves the installation flexibility and adaptability of the mechanism.

[0065] The height of the vertical plate 1 can be adjusted. The overall height of the vertical plate 1 and the guide roller 4 can be flexibly adjusted according to the height of different fiber conveying lines and the docking requirements of different processing equipment. This allows the guide roller 4 to accurately match the fiber conveying path, avoiding fiber deviation and abnormal tension caused by mismatched conveying heights, and further adapting to the diverse conveying needs of different fibers.
