Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for warping machines, and specifically relates to a warping machine wire feeding frame. Background Technology

[0002] In the manufacturing process of metal wire mesh, warping is the core pre-process that determines the accuracy of the warp arrangement and the quality of the finished product. Its function is to organize multiple warp yarns according to the set number, width and arrangement, and evenly wind them onto the warp beam to provide qualified warp yarns for subsequent weaving processes.

[0003] In existing technologies, warping machines typically employ a vertical unwinding frame, with several unwinding spools arranged in an array or circumferential distribution on the frame. Each unwinding spool carries warp yarns and simultaneously unwinds them. The yarns converge from various points on the frame towards the central yarn-gathering and guiding area, and then enter the winding station after being guided. However, due to the arrangement of the unwinding spools, the spatial distance between different unwinding spools and the yarn-gathering point, as well as the yarn exit angle, vary. Unwinding spools at the edges have larger yarn exit angles and longer yarn paths, resulting in greater frictional resistance between the yarn and the guiding elements, and higher operating tension, which can easily exceed the tensile load of the metal wire and cause yarn breakage. Unwinding spools at the center have lower yarn exit resistance and lower tension, resulting in slack yarns lacking tension constraint, which can easily lead to yarn tangling or detachment from the spool due to the inertia of the unwinding spool. This overall uneven tension also causes inconsistent density between warp beam winding layers, affecting the stability of subsequent weaving and the accuracy and structural strength of the finished mesh. Summary of the Invention

[0004] This invention provides a warping machine feeder, which aims to improve the tension consistency of warp yarns and reduce the production failure rate.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A warping machine feeder frame is provided, comprising a frame, multiple elastic tensioning parts, and multiple adjusting parts. The frame is provided with multiple feed shafts arranged in a rectangular array. Each elastic tensioning part corresponds one-to-one with a feed shaft. The elastic tensioning part is wound around the corresponding feed shaft to provide a clamping force on the feed shaft. Each adjusting part corresponds one-to-one with the multiple elastic tensioning parts. Each adjusting part has multiple fixing holes, and the distance between the axis of the fixing hole and the axis of the feed shaft is defined as a first distance, with each first distance being different. One end of each elastic tensioning part is connected to the frame, and the other end is detachably connected to any fixing hole of the corresponding adjusting part. The elastic tensioning part can connect to different fixing holes to adjust the clamping force on the feed shaft.

[0006] In one possible implementation, the elastic tensioning part includes a brake band and an elastic element. The brake band is wound around the shaft of the pay-off spool and one end is connected to the frame. One end of the elastic element is connected to the brake band, and the other end is detachably connected to one of the fixing holes. The elastic element is used to apply an elastic tension to the brake band so that the brake band tends to press against the pay-off spool.

[0007] In some embodiments, the frame is further provided with multiple mounting rods arranged side by side, and the mounting rods are vertically arranged. Among them, multiple adjusting parts in the same column are spaced apart on the same mounting rod.

[0008] For example, the warping machine's feeder also includes a tension adjustment assembly, which is mounted on the frame and has a pull-out portion connected to each mounting rod. The pull-out portion is used to change the height of each mounting rod to change the clamping force of the elastic tensioning portion on the feeder shaft.

[0009] For example, the tensioning assembly includes a slide plate, a drive structure, and multiple transmission structures. The slide plate is slidably mounted on the frame along a first direction. The first direction is the parallel orientation of multiple pay-off spools. The drive structure is mounted on the frame and poweredly connected to the slide plate, used to drive the slide plate to slide along the first direction on the frame. Multiple transmission structures are all mounted on the frame. One end of each transmission structure is connected to the slide plate, and the other end is connected to the end of a mounting rod, used to convert the sliding motion of the frame into vertical movement of each mounting rod.

[0010] In one possible implementation, the drive structure includes a swing arm, a sliding column, and a telescopic drive component. One end of the swing arm is rotatably mounted on the frame, with its axis of rotation vertically aligned. The other end of the swing arm has a groove extending along its length. The sliding column is vertically mounted on the slide plate and slides into the groove. The telescopic drive component is mounted on the frame, with its output end connected to the swing arm. The telescopic drive component drives the swing arm to swing around its axis of rotation, causing the groove to push the sliding column and thus drive the slide plate to slide horizontally on the frame.

[0011] In some embodiments, the transmission structure includes a drive wheel and a drive belt. The drive wheel is rotatably mounted on the frame. The drive belt is wound around the drive wheel, with one end connected to the top of the mounting rod and the other end connected to the bottom of the slide plate.

[0012] For example, the frame is provided with multiple beams extending along a first direction, which is the parallel direction of multiple wire feeding shafts. The multiple beams are distributed vertically at intervals, and each beam has multiple through holes. The multiple through holes are arranged at intervals along the first direction, and the through holes on the same vertical line of adjacent beams are aligned one-to-one. The mounting rod passes vertically through the multiple vertically aligned through holes.

[0013] For example, the adjusting part is slidably connected to the mounting rod, and the adjusting part is provided with a fastener, which is used to lock the position of the adjusting part on the mounting rod.

[0014] In one possible implementation, multiple wire-laying plates are provided on the side wall of the frame, with each wire-laying plate spaced apart in the vertical direction. Each wire-laying plate is provided with multiple wire-laying holes, and the warp threads on multiple pay-off shafts located at the same height are respectively passed through the multiple wire-laying holes.

[0015] The beneficial effects of the warping machine feeder provided by this invention are as follows: Compared with the prior art, this invention uses multiple elastic tensioning parts and adjusting parts to match the feeder shafts arranged in a rectangular array on the machine frame. The elastic tensioning parts are wound around the feeder shafts, and multiple fixing holes with different first distances on the adjusting part allow for selective connection of the elastic tensioning parts. For feeder shafts located at different positions in the array, by fixing the elastic tensioning parts to different fixing holes, the pre-tension stroke of the elastic tensioning parts is changed, and the clamping force on the feeder shafts is adjusted. This reduces tension deviations caused by differences in yarn path length and bend angle, achieving autonomous tension balance across the entire array of feeder shafts, reducing yarn breakage and tangling, improving warp yarn tension consistency, and lowering the production failure rate.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on the other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0020] Please refer to the following: Figure 1 and Figure 2 The warping machine feeder provided by the present invention will now be described. The warping machine feeder includes a frame 10, a plurality of elastic tensioning parts 30, and a plurality of adjusting parts 40. The frame 10 has a plurality of feed shafts 20 arranged in a rectangular array. Each elastic tensioning part 30 corresponds one-to-one with a feed shaft 20. The elastic tensioning part 30 is wound around the corresponding feed shaft 20 to provide a clamping force on the feed shaft 20. Each adjusting part 40 corresponds one-to-one with a plurality of elastic tensioning parts 30. Each adjusting part 40 has a plurality of fixing holes 41, and the distance between the axis of the fixing hole 41 and the axis of the feed shaft 20 is defined as a first distance, and each first distance is different. One end of each elastic tensioning part 30 is connected to the frame 10, and the other end is detachably connected to any one of the fixing holes 41 of the corresponding adjusting part 40. The elastic tensioning part 30 can connect to different fixing holes 41 to adjust the clamping force on the feed shaft 20.

[0021] It should be noted that the frame 10 is equipped with multiple pay-off spools 20, which are arranged neatly in rows and columns in both horizontal and vertical directions. This allows for the maximum number of pay-off spools 20 to be arranged within a limited space, thus meeting the warp yarn count requirements of the warping process. The rectangular array ensures that the position of each row or column of pay-off spools 20 is regular, providing a structural basis for subsequent unified tension management.

[0022] Each pay-off spool 20 is equipped with an independent elastic tensioning part 30, a portion of which contacts and covers the circumferential surface of the pay-off spool 20. Under the action of its own elastic potential energy, the elastic tensioning part 30 applies a clamping force towards the axis of the pay-off spool 20. This clamping force generates friction on the surface of the pay-off spool 20, creating a damping effect on its rotational movement. This damping effect suppresses the inertial rotation of the pay-off spool 20 during the pay-off process, preventing the warp yarn from becoming loose or tangled due to excessive release.

[0023] The adjusting part 40 has multiple fixing holes 41, which are used for hooking or fixing the movable end of the elastic tensioning part 30. On each adjusting part 40, the fixing holes 41 are located in different positions, resulting in different first distances between the axis of each fixing hole 41 and the axis of the pay-off shaft 20. Some fixing holes 41 are closer to the axis of the pay-off shaft 20, while others are farther away.

[0024] One end of the elastic tensioning part 30 is fixedly connected to the frame 10, and the other end is a movable end. The movable end can be selectively and detachably connected to any one of the fixing holes 41 of the corresponding adjusting part 40. The detachable connection can be a hook connection. When the movable end of the elastic tensioning part 30 is connected to different fixing holes 41, the pre-stretch length of the elastic tensioning part 30 will change. Since the initial distance of each fixing hole 41 is different, when the movable end is connected to a fixing hole 41 farther from the axis of the pay-off shaft 20, the elastic tensioning part 30 is stretched longer, and the elastic potential energy stored inside is greater, thereby increasing the clamping force applied to the pay-off shaft 20. Conversely, when the movable end is connected to a fixing hole 41 closer to the axis of the pay-off shaft 20, the stretch of the elastic tensioning part 30 decreases, and the clamping force decreases accordingly.

[0025] During the operation of the warping machine, the pay-off shafts 20 located at the edges of the rectangular array require greater pay-off damping to prevent slack due to their longer pay-off paths and larger bends. In this case, the elastic tensioning part 30 at this location is attached to a fixing hole 41 with a larger initial distance to increase the clamping force. The pay-off shafts 20 located in the middle of the rectangular array require less pay-off damping to prevent wire breakage due to their shorter pay-off paths and lower resistance. In this case, the elastic tensioning part 30 at this location is attached to a fixing hole 41 with a smaller initial distance to reduce the clamping force. The operator can independently select the most suitable attachment point based on the specific location of each pay-off shaft 20.

[0026] Compared with existing technologies, the warping machine feeder provided by this invention uses multiple elastic tensioning parts 30 and adjusting parts 40 to match the feeder shafts 20 arranged in a rectangular array on the frame 10. The elastic tensioning parts 30 are wound around the feeder shafts 20. Multiple fixing holes 41 with different first distances on the adjusting part 40 allow the elastic tensioning parts 30 to be selectively connected. For feeder shafts 20 located at different positions in the array, by fixing the elastic tensioning parts 30 to different fixing holes 41, the pre-tension stroke of the elastic tensioning parts 30 is changed, and the clamping force on the feeder shafts 20 is adjusted. This reduces tension deviations caused by differences in yarn path length and bend angle, achieving autonomous tension balance across the entire array of feeder shafts 20, reducing yarn breakage and tangling, improving warp yarn tension consistency, and lowering the production failure rate.

[0027] Please see Figure 3 The elastic tensioning part 30 includes a brake band 31 and an elastic member 32. The brake band 31 is wound around the rotating shaft of the pay-off spool 20, and one end is connected to the frame 10. One end of the elastic member 32 is connected to the brake band 31, and the other end is detachably connected to one of the fixing holes 41. The elastic member 32 is used to apply an elastic tension to the brake band 31 so that the brake band 31 tends to press against the pay-off spool 20.

[0028] It should be noted that the brake band 31 can be made of a flexible material with a high coefficient of friction, such as a wear-resistant rubber band or a braided brake band. The shaft is the main part of the pay-off shaft 20 that supports the wire coil and allows it to rotate. The brake band 31 is wound around the shaft of the pay-off shaft 20. A portion of the brake band 31 covers the outer circumference of the shaft, forming a frictional contact surface between the two. One end of the brake band 31 is fixedly connected to the frame 10, which can be done by riveting or bolting, keeping one end of the brake band 31 stationary as a fulcrum for applying force.

[0029] The elastic element 32 can be a component with linear tensile properties, such as a helical tension spring or an elastic rod. One end of the elastic element 32 is connected to the brake band 31, with the connection point located near the movable end of the brake band 31, typically at the end of the brake band 31 furthest from the fixed point of the frame 10. The other end of the elastic element 32 is detachably connected to any of the fixing holes 41 in the adjusting part 40. The elastic element 32 is used to apply a continuous elastic tension to the brake band 31.

[0030] In operation, the elastic element 32 continuously pulls the movable end of the brake band 31 through its own elastic recoil tendency. Since the middle section of the brake band 31 is wound around the rotating shaft, the tension of the elastic element 32 is converted into a normal pressure of the brake band 31 on the surface of the rotating shaft, causing the brake band 31 to adhere tightly to the rotating shaft, thereby generating a frictional torque that hinders the rotation of the rotating shaft. The brake band 31 has a tendency to press against the unwinding shaft 20. When the rotating shaft vibrates due to unwinding, the rebound force of the elastic element 32 can compensate for this, maintaining the stability of the clamping force.

[0031] By attaching the end of the elastic element 32 to the fixing holes 41 at different positions, the pre-tension length of the elastic element 32 can be changed. When attached to the fixing hole 41 farther from the axis of rotation, the stretch of the elastic element 32 increases, the rebound force is enhanced, the clamping force of the brake band 31 on the shaft increases accordingly, and the wire feeding damping is improved. When attached to the fixing hole 41 closer to the shaft, the elastic element 32 is more relaxed, the rebound force is weakened, and the damping is reduced. The brake band 31 provides a stable friction interface, and the elastic element 32 provides an adjustable power source. The two work together to achieve fine control of the resistance of the wire feeding shaft 20, overcoming the problem of narrow adjustment range and easy fatigue failure of a single friction plate structure.

[0032] Please see Figure 1 and Figure 2 The frame 10 is also provided with multiple mounting rods 11 arranged side by side, and the mounting rods 11 are arranged vertically. Among them, multiple adjustment parts 40 in the same row are spaced apart on the same mounting rod 11.

[0033] It should be noted that multiple mounting rods 11 are arranged parallel to each other in the horizontal direction and at certain intervals. The axis of the mounting rods 11 is perpendicular to the horizontal plane and extends from top to bottom. Multiple adjusting parts 40 in the same column are spaced apart on the same mounting rod 11. The wire feeding shafts 20 in the rectangular array form a column in the vertical direction. Correspondingly, all the adjusting parts 40 in this column are concentrated on the same vertical mounting rod 11. The adjusting parts 40 maintain a certain distance from the height of the mounting rod 11 to avoid other components below or above. Each adjusting part 40 has an independent operating space.

[0034] Mounting rod 11 integrates the adjustment parts 40 in the same column into a modular whole, which simplifies the manufacturing process of frame 10. It eliminates the need to separately machine positioning structures for each adjustment part 40 on frame 10. It also creates the physical conditions for subsequent batch adjustments. By controlling the overall displacement of mounting rod 11, all adjustment parts 40 in the column can be moved synchronously, thereby changing the tension state of the entire column of elastic tensioning parts 30. This helps reduce the structural complexity of the entire machine and enhances the overall integrity of the equipment.

[0035] Please see Figure 4 The warping machine's wire feeding frame also includes a tension adjustment assembly 50, which is mounted on the frame 10 and has a pull-out part connected to each mounting rod 11. The pull-out part is used to change the height of each mounting rod 11 to change the clamping force of the elastic tensioning part 30 on the wire feeding shaft 20.

[0036] It should be noted that the pulling part is the part of the tensioning assembly 50 that directly performs displacement output and is connected to each mounting rod 11. A single action of the pulling part can be transmitted to all mounting rods 11 simultaneously.

[0037] In operation, the pulling part moves vertically, causing all connected mounting rods 11 to rise or fall synchronously. Since the mounting rods 11 are vertically positioned and the adjusting part 40 is fixed to them, changes in the height of the mounting rods 11 directly affect the height of the adjusting part 40. Raising or lowering the position of the adjusting part 40 changes its relative distance to the fixed point on the frame 10.

[0038] This change in height directly affects the elastic tensioning section 30. One end of the elastic element 32 of the elastic tensioning section 30 is connected to the brake band 31, and the other end is connected to the fixing hole 41 of the adjusting section 40. When the adjusting section 40 moves upward with the mounting rod 11, the position of the fixing hole 41 rises, the elastic element 32 is further stretched, and its tension on the brake band 31 increases, thereby increasing the clamping force of the brake band 31 on the pay-off shaft 20. Conversely, when the adjusting section 40 moves downward, the stretch of the elastic element 32 decreases, and the clamping force decreases accordingly. The tension adjustment assembly 50 achieves synchronous adjustment of the tension of all pay-off shafts 20 of the entire machine. Operators do not need to adjust each elastic tensioning section 30 individually; they only need to operate the tension adjustment assembly 50 to quickly respond to the overall tension requirements of different specifications of warp yarns. This improves work efficiency, ensures the consistency of warp yarn tension in the same batch, solves the problems of errors and time waste caused by manual point-by-point adjustment, and makes the equipment flexible and adaptable when facing different production process switching.

[0039] Please see Figure 5 and Figure 6 The tension adjustment assembly 50 includes a slide plate 51, a drive structure 52, and multiple transmission structures 53. The slide plate 51 is slidably mounted on the frame 10 along a first direction. The first direction is the parallel orientation of the multiple pay-off shafts 20. The drive structure 52 is mounted on the frame 10 and is poweredly connected to the slide plate 51, used to drive the slide plate 51 to slide along the first direction on the frame 10. Multiple transmission structures 53 are all mounted on the frame 10. One end of each transmission structure 53 is connected to the slide plate 51, and the other end is connected to the end of a mounting rod 11, used to convert the sliding of the frame 10 into vertical movement of each mounting rod 11.

[0040] It should be noted that the first direction is defined as the parallel direction of the multiple pay-off spools 20, i.e., horizontal. A guide mechanism is provided between the slide plate 51 and the frame 10, which can cooperate with the guide rail and the slide groove 524 to ensure that the slide plate 51 can only make linear reciprocating motion along the first direction, avoiding deflection or jamming. The drive structure 52 is the power source of the tension adjustment component 50, which can convert its own power output into linear motion of the slide plate 51, driving the slide plate 51 to slide along the first direction on the frame 10.

[0041] The number of transmission structures 53 matches the number of mounting rods 11, with each transmission structure 53 corresponding to one mounting rod 11. One end of the transmission structure 53 is connected to the slide plate 51, and the other end is connected to the end of the mounting rod 11. When the drive structure 52 pushes the slide plate 51 to move in the first direction, the slide plate 51 drives the input ends of all transmission structures 53 to move synchronously. The transmission structure 53 can convert the horizontal displacement of the slide plate 51 into the vertical lifting motion of the mounting rod 11.

[0042] The drive structure 52 only needs to output force in one direction, which is distributed to each transmission structure 53 via the slide plate 51. The transmission structures 53 then drive the corresponding mounting rods 11. All mounting rods 11 are driven by the same slide plate 51, and the movement distance and speed are consistent, with the tension changes of all pay-off shafts 20 synchronized. While ensuring sufficient adjustment stroke, the load requirements of the drive structure 52 are reduced, making the equipment operate more smoothly and reliably, and facilitating automated control.

[0043] Please see Figure 5 The drive structure 52 includes a swing arm 521, a slide column 522, and a telescopic drive component 523. One end of the swing arm 521 is rotatably mounted on the frame 10, and its rotation axis is vertical. The other end of the swing arm 521 has a slide groove 524 that extends along the length of the swing arm 521. The slide column 522 is vertically mounted on the slide plate 51 and slides in cooperation with the slide groove 524. The telescopic drive component 523 is mounted on the frame 10, and its output end is connected to the swing arm 521. The telescopic drive component 523 is used to drive the swing arm 521 to swing around its rotation axis, so that the slide groove 524 pushes the slide column 522 and drives the slide plate 51 to slide horizontally on the frame 10.

[0044] It should be noted that one end of the swing arm 521 is rotatably mounted on the frame 10 via a slewing bearing, and its axis of rotation extends vertically, allowing the swing arm 521 to swing freely in the horizontal plane. The other end of the swing arm 521 is provided with a slide groove 524. The slide groove 524 is formed along the length of the swing arm 521 and is typically machined as an elongated through-hole to accommodate the sliding column 522 and provide a guide trajectory.

[0045] A sliding column 522 is vertically mounted on the slide plate 51. The lower end of the sliding column 522 is firmly connected to the top surface of the slide plate 51, while the upper end extends upwards and passes through the groove 524 of the swing arm 521. The cylindrical surface of the sliding column 522 maintains close contact with the inner wall of the groove 524, forming a sliding fit. When the swing arm 521 swings around its axis, the side wall of the groove 524 applies a thrust to the sliding column 522, causing it to move linearly in the first direction. Because the sliding column 522 is rigidly connected to the slide plate 51, the movement of the sliding column 522 directly drives the slide plate 51 to slide synchronously on the frame 10. This linkage transmission method efficiently converts the rotational motion of the swing arm 521 into the linear motion of the slide plate 51, and has good self-locking and stability.

[0046] The telescopic drive component 523 serves as the power source and is mounted on the frame 10. The telescopic drive component 523 can be a chain and sprocket transmission mechanism, including a driving sprocket, a driven sprocket, and a chain wrapped around the sprockets. The driving sprocket is connected to the output shaft of the drive motor, and the driven sprocket is rotatably mounted on the frame 10. The chain is sleeved between the driving sprocket and the driven sprocket to form a closed loop. The chain is connected to the swing arm 521. During operation, the drive motor drives the driving sprocket to rotate, which in turn drives the driven sprocket to rotate via the chain. As the chain rotates, it moves the end of the swing arm 521, which is fixed to it, forcing the swing arm 521 to reciprocate around its vertical axis. The swing of the swing arm 521 transmits power to the slide plate 51 through the cooperation of the sliding groove 524 and the sliding column 522, thereby driving the slide plate 51 to slide smoothly along the first direction.

[0047] Utilizing the lever principle of the swing arm 521, a large output torque can be obtained with a small driving force, reducing the power requirements of the telescopic drive component 523. Simultaneously, the cooperation between the slide groove 524 and the slide column 522 can adapt to the non-linear trajectory of the swing arm 521 during swing, ensuring the smooth movement of the slide plate 51. The telescopic drive component 523 and related transmission components are arranged on the side of the frame 10, avoiding the wire channel on the front of the frame 10, optimizing the equipment space layout, facilitating operators to observe the wire's operating status from the front, and preventing the drive components from obstructing the view.

[0048] In this embodiment, a torsion spring or similar elastic energy storage element is added at the rotational connection of the swing arm 521. The rebound element is sleeved on the vertical shaft of the swing arm 521, with one end abutting against the frame 10 and the other end abutting against the body of the swing arm 521. In the initial state, the rebound element is in a pre-torsional state, accumulating elastic potential energy that drives the swing arm 521 to swing away from the telescopic drive member 523.

[0049] During operation, when the telescopic drive component 523, i.e., the chain and sprocket transmission mechanism, is in a pulled state, the chain overcomes the resistance of the springback element and pulls the swing arm 521 to swing. At this time, the springback element further twists and stores energy. When the telescopic drive component 523 releases the chain, the elastic potential energy stored in the springback element is released, generating a reverse rotational torque, which forces the swing arm 521 to swing back to its initial position around its vertical axis.

[0050] When the swing arm 521 springs back to its original position, it drives the sliding column 522 to move in the opposite direction within the sliding groove 524, thereby driving the slide plate 51 to slide away from the telescopic drive member 523. The reverse movement of the slide plate 51 is quickly transmitted to the mounting rod 11 via the transmission belt 532, causing the mounting rod 11 to descend rapidly under the assistance of gravity, thereby releasing the clamping force of the elastic tensioning part 30 on the wire feeding shaft 20. The spring-loaded element provides a constant restoring force, which can keep the transmission belt 532 in a taut state, preventing the transmission belt 532 from skipping teeth or slipping due to slack, improving the accuracy and reliability of the overall tension adjustment, and making the equipment more responsive when switching between different tension levels.

[0051] Please see Figure 6 The transmission structure 53 includes a transmission wheel 531 and a transmission belt 532. The transmission wheel 531 is rotatably mounted on the frame 10. The transmission belt 532 is wound around the transmission wheel 531, with one end connected to the top of the mounting rod 11 and the other end connected to the bottom of the slide plate 51.

[0052] It should be noted that the frame 10 provides rotational support for the drive wheel 531, and the axis of rotation of the drive wheel 531 is horizontally set, enabling smooth fixed-axis rotation. The drive wheel 531 can be a smooth-surfaced roller. The drive belt 532 has a certain degree of flexibility and tensile strength, and can be made of high-strength fiber belt.

[0053] During operation, when the slide plate 51 slides towards the telescopic drive member 523, it pulls the transmission belt 532, which in turn pulls the top of the mounting rod 11, causing it to move vertically upwards. Conversely, when the slide plate 51 slides away from the telescopic drive member 523, the transmission belt 532 slackens, and the mounting rod 11 falls back downwards under its own weight or the action of the reset mechanism. The use of the transmission wheel 531 reduces the frictional resistance of the transmission belt 532 during bending and movement, improving energy transfer efficiency. Simultaneously, the transmission belt 532 has elastic buffering properties, absorbing instantaneous impacts during equipment operation and preventing the impact of rigid impacts on the precision wires. This flexible connection method allows multiple mounting rods 11 to rise and fall synchronously and smoothly with the slide plate 51, improving the uniformity and stability of the tension adjustment of the entire frame 10.

[0054] Please see Figure 1 and Figure 2The frame 10 has multiple beams 12 extending along a first direction, which is the parallel direction of multiple wire feeding shafts 20. The beams 12 are distributed vertically at intervals, and each beam 12 has multiple through holes 13. These through holes 13 are spaced apart along the first direction, with the through holes 13 on adjacent beams 12 aligned on the same vertical line. Mounting rods 11 are inserted vertically into the vertically aligned through holes 13.

[0055] It should be noted that the beam 12, as the main lateral support component of the frame 10, can enhance the overall bending stiffness of the frame 10. Multiple beams 12 are distributed at intervals along the vertical direction, forming a multi-layer frame structure inside the frame 10, which can resist the lateral overturning moment of the equipment during operation.

[0056] Perforations 13 penetrate the upper and lower surfaces of the beam 12 for the mounting rod 11 to pass through. Multiple perforations 13 are spaced apart along a first direction, the spacing of which matches the horizontal array spacing of the wire-laying shafts 20. In two adjacent beams 12, a perforation 13 on the upper beam 12 has a coaxial perforation 13 on the lower beam 12 directly below it. These vertically aligned perforations 13 form a guide channel for the mounting rod 11.

[0057] The mounting rod 11 is vertically inserted into multiple aligned perforations 13. A small clearance exists between the outer contour of the mounting rod 11 and the inner diameter of the perforations 13, allowing the mounting rod 11 to move freely axially within the perforations 13 while limiting its radial displacement in the horizontal plane. This transforms the stress state of the mounting rod 11 from a cantilever beam to a multi-span continuous beam. When the tensioning assembly 50 pulls the mounting rod 11 up or down, multiple beams 12 share the lateral shear force on the mounting rod 11, improving its bending resistance. The aligned perforations 13 act as guide sleeves, restricting the mounting rod 11 to linear movement only in the vertical direction, reducing jamming caused by tilting. This keeps the entire row of mounting rods 11 parallel during lifting and lowering, providing a stable installation reference for the elastic tensioning part 30 and improving the accuracy and consistency of tension adjustment.

[0058] Please see Figure 2 The adjusting part 40 is slidably connected to the mounting rod 11. The adjusting part 40 is provided with a fastener 42, which is used to lock the position of the adjusting part 40 on the mounting rod 11.

[0059] It should be noted that this sliding connection refers to the adjusting part 40 having a guide hole or groove that matches the cross-sectional shape of the mounting rod 11, with the mounting rod 11 passing through the guide structure. The adjusting part 40 can reciprocate vertically along the axis of the mounting rod 11. The position of the adjusting part 40 relative to the mounting rod 11 is not fixed, and it has a continuous adjustment stroke. The operator can flexibly adjust the specific height of the adjusting part 40 on the mounting rod 11 according to actual needs.

[0060] The adjusting part 40 is also provided with a fastener 42. The fastener 42 can be a set screw, a locking bolt, or a quick-release handle. The fastener 42 is provided on the body of the adjusting part 40 and can abut or press against the surface of the mounting rod 11. The fastener 42 is used to lock the position of the adjusting part 40 on the mounting rod 11. When the adjusting part 40 is moved to the target height, tighten the fastener 42, and use the friction or mechanical engagement between the fastener 42 and the mounting rod 11 to firmly fix the adjusting part 40 in the current position, preventing it from slipping due to vibration during equipment operation.

[0061] In actual production, even if the elastic tensioning part 30 is attached to different fixing holes 41 of the same adjusting part 40, or the tension adjustment component 50 is used for coarse adjustment of the overall tension, there may still be slight deviations in the tension of individual pay-off shafts 20. In this case, the operator does not need to modify the elastic element 32 or the overall structure; they only need to loosen the fastener 42 and finely adjust the position of the adjusting part 40 corresponding to the pay-off shaft 20 up and down to change the pre-tightening reference of the elastic tensioning part 30, thus achieving fine correction of the tension of a single shaft. The reliable locking force provided by the fastener 42 ensures that the adjusted position remains stable even under long-term high-speed operation, improving the equipment's adaptability to different working conditions and the accuracy of tension control.

[0062] Please see Figure 1 Multiple wire-laying plates 14 are provided on the side wall of the frame 10. Each wire-laying plate 14 is spaced apart in the vertical direction. Each wire-laying plate 14 is provided with multiple wire-laying holes 15. The warp threads on multiple pay-off shafts 20 located at the same height are respectively passed through the multiple wire-laying holes 15.

[0063] It should be noted that the array distribution of each wire-laying plate 14 and the wire-feeding shaft 20 is matched, so that each layer of wire-laying plate 14 corresponds to processing a row of wire-feeding shafts 20 at the same horizontal height.

[0064] Each wire guide plate 14 is provided with multiple wire guide holes 15. The wire guide holes 15 penetrate the surface of the wire guide plate 14, and their diameter is slightly larger than the diameter of the warp wire. The multiple wire guide holes 15 are evenly distributed along the length of the wire guide plate 14, and the center distance between the holes is equal to the axial distance between two adjacent pay-off shafts 20 at the same height. The warp wires on the multiple pay-off shafts 20 located at the same height are respectively passed through the multiple wire guide holes 15. After each warp wire is led out from the pay-off shaft 20, it accurately passes through the corresponding wire guide hole 15 on the wire guide plate 14 and is then fed to the next process.

[0065] After being processed by the elastic tensioning section 30 and the tension adjustment assembly 50, the warp threads, although their tension has become more uniform, still exhibit slight vibrations or phase differences when leaving the pay-off shaft 20. The warp thread guide hole 15 applies physical constraints to the warp threads, forcing them to travel along a predetermined straight path and eliminating crossovers and tangles between the threads. The warp thread guide plate 14 aligns multiple warp threads at the same height in a vertical plane, ensuring that the threads are arranged in a parallel and equidistant manner before entering the yarn gathering area. This pre-shaping process reduces the burden on the subsequent guide rollers and improves the flatness of the warp thread sheet. When the tension adjustment assembly 50 moves, causing the mounting rod 11 to rise and fall, the warp thread guide plate 14 can buffer the instantaneous fluctuations in the threads caused by tension changes, preventing the threads from jumping off the preset track.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
