Description

Technical Field

[0001] This invention belongs to the technical field of photovoltaic wire mesh weaving equipment, specifically relating to a warp combing device for a photovoltaic wire mesh weaving machine. Background Technology

[0002] Photovoltaic wire mesh is a core auxiliary material in the production process of photovoltaic cells, mainly used for electrode printing in crystalline silicon cells. Its weaving precision, uniformity, and flatness directly determine the photoelectric conversion efficiency and finished product quality of the cells. Photovoltaic wire mesh is woven from ultra-fine metal warp and weft threads. The uniform combing and stable feeding of the warp threads are key processes to ensure the quality of wire mesh weaving.

[0003] In the existing technology, the warp combing device of traditional photovoltaic wire mesh weaving machine mostly adopts a single structure of fixed combing plate. The combing spacing and height are fixed parameters, which easily leads to the deviation of single warp threads and uneven spacing. This results in inconsistent mesh size after weaving, affecting the uniformity of solar cell printing and failing to meet the production needs of multi-model, high-precision photovoltaic wire mesh. Summary of the Invention

[0004] This invention provides a warp combing device for a photovoltaic wire mesh weaving machine, which aims to solve the problems of existing devices.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a warp combing device for a photovoltaic wire mesh weaving machine, comprising: The frame is fixed at the warp thread conveying path of the photovoltaic wire mesh weaving machine; A combing module is mounted on the frame. The combing module includes three sets of independent combing units spaced apart along the warp transmission direction. Each set of combing units includes multiple combing units spaced apart along the warp arrangement direction. Each combing unit can be slidably arranged along the warp arrangement direction. Each combing unit has a combing section through which the warp threads pass. A tension adjustment mechanism is mounted on the frame and is connected to each of the combing units for synchronous adjustment of the spacing of each combing unit along the warp conveying direction, so as to provide constraint when the warp deviates or the tension fluctuates.

[0006] In one possible implementation, the tension adjustment mechanism includes: Two tension adjustment structures are spaced apart on the frame along the warp direction. Each tension adjustment structure is arranged along the warp transmission direction and is connected to one end of each combing unit to synchronously adjust the spacing between the combing units on both sides and the combing unit in the middle along the warp conveying direction. Each tension adjustment structure is drivenly connected to one end of each combing unit to make each combing unit rotate synchronously, with the rotation axis arranged along the warp direction. The rotation drive structure is connected to the two tension adjustment structures in a transmission manner.

[0007] In one possible implementation, the tension adjustment structure includes: Tension adjustment frame, arranged along the transmission direction of the warp, has adjustment cavities that extend through the intervals of each warp. The drive gear is rotatably disposed in the adjustment cavity, with its rotation axis arranged along the interval direction of each warp line. One end of the drive gear is connected to the power output end of the rotation drive structure, and the drive gear is fixedly connected to the combing unit located in the middle. A sliding gear is slidably mounted on the driving gear along the interval direction of each meridian and rotates synchronously with the driving gear. Two sliding structures are arranged circumferentially along the axis of the drive gear and are both slidably disposed in the adjustment cavity along the conveying direction of the warp. The two sliding structures move relative to each other or back to back when the drive gear rotates. One end of each sliding structure has a rack portion that meshes with the sliding gear, and the other end of each sliding structure extends toward the side away from the sliding gear. Two driven gears are provided in one-to-one correspondence with the two sliding structures. Each driven gear is rotatably mounted on the protruding end of the corresponding sliding structure. The two driven gears are fixedly connected to the two combing units located at both ends. A tensioning belt is wound around the outside of the driving gear and the two driven gears.

[0008] In one possible implementation, each of the sliding structures includes: A sliding rack is provided along the conveying direction of the warp, with one end meshing with the sliding gear and the other end extending outward and away from the sliding gear along the conveying direction of the warp. The sliding rack is the rack section. A sliding bracket is disposed on the extended end of the sliding rack, and the sliding bracket is used for rotatably connecting the corresponding driven gear.

[0009] In one possible implementation, the tensioning belt has multiple contact engagement sections and multiple tension compensation sections, with each contact engagement section and each tension compensation section spaced apart. Each contact engagement section engages with the driving gear or the driven gear. The tension compensation sections are used to compensate for tension when the distance between each driven gear and the driving gear changes.

[0010] In one possible implementation, there are two sliding gears, which are arranged on both sides of the driving gear along the interval direction of each meridian; there are two sliding racks, which are arranged in one-to-one correspondence with the two sliding gears. The drive gear has guide posts on both sides along the interval direction of each meridian for sliding of each sliding gear. When each sliding gear is close to the drive gear, it meshes with the corresponding sliding rack. When each sliding gear is away from the drive gear, it disengages from the corresponding sliding rack.

[0011] In one possible implementation, the warp combing device for the photovoltaic wire mesh weaving machine further includes a tension feedback module, which abuts against the warp threads and is used to detect the tension value of the warp threads in real time, and control the start / stop and rotation speed of the rotation drive structure according to the tension value.

[0012] In one possible implementation, each combing unit further includes a connecting shaft, which is arranged along the interval direction of each warp thread. The two ends of each connecting shaft are respectively connected to two driving gears or two corresponding driven gears, and each connecting shaft is slidably connected to the corresponding combing unit.

[0013] In one possible implementation, each of the comb units includes: A sliding bushing is slidably mounted on the connecting shaft; The comb block has one end fixed on the sliding bushing and the other end extending radially along the connecting shaft; A combing wheel is rotatably mounted on the extended end of the combing block, with its rotation axis parallel to and spaced apart from the axis of the connecting shaft. The combing wheel is provided with a combing groove for accommodating the warp threads, and an anti-detachment ring is fitted onto the combing groove. The combing wheel and the anti-detachment ring together constitute the combing part.

[0014] In one possible implementation, damping is provided between the sliding bushing and the connecting shaft, and damping is provided between the combing wheel and the combing block.

[0015] In this implementation, compared with the prior art, by arranging three groups of combing units spaced apart along the warp transmission direction of the combing module, the integrated rigid structure of the traditional fixed combing plate is broken. This allows the warp to form multi-point support along the transmission path, effectively suppressing the sagging or resonance of the warp caused by long-distance suspended transmission. Multiple combing units within each combing unit can slide along the warp arrangement direction. Operators can adjust the spacing between adjacent combing units in real time according to the warp diameter, ensuring that the constraint stiffness of the warp within the combing section is moderate. This avoids warp swaying due to excessive gaps or scratches due to insufficient gaps. Each combing unit has the function of adjusting warp tension. Combined with the tension adjustment mechanism, the spacing of each combing unit along the transmission direction is adjusted synchronously, enabling the device to generate constraint force through overall displacement when the warp experiences transient offset or tension fluctuations.

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.

Therefore, they should not be construed as limitations on the present invention.

[0019] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a structure. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Furthermore, 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0021] Please refer to the following: Figures 1 to 6 The warp combing device for a photovoltaic wire mesh weaving machine provided by the present invention will now be described. The warp combing device for a photovoltaic wire mesh weaving machine includes a frame 10, a combing module 20, and a tension adjusting mechanism 30. The frame 10 is fixedly mounted on the warp thread transport path of the photovoltaic wire mesh weaving machine. The combing module 20 is mounted on the frame 10 and includes three sets of independent combing units 21 spaced apart along the warp thread transport direction. Each combing unit 21 includes multiple combing elements 211 spaced apart along the warp thread arrangement direction. Each combing element 211 can be slidably arranged along the warp thread arrangement direction, and each combing element 211 has a combing section through which the warp thread passes. The tension adjusting mechanism 30 is mounted on the frame 10 and is drivenly connected to each combing unit 21. It is used to synchronously adjust the spacing of each combing unit 21 along the warp thread transport direction to provide constraint when the warp thread deviates or tension fluctuates.

[0022] The warp combing device for a photovoltaic wire mesh weaving machine provided in this embodiment, compared with the prior art, breaks the traditional rigid structure of the fixed combing plate by arranging three sets of combing units 21 at intervals along the warp transmission direction of the combing module 20. This allows the warp to form multi-point support along the transmission path, effectively suppressing the sagging or resonance of the warp caused by long-distance suspended transmission. Multiple combing units 211 within each combing unit 21 can slide along the warp arrangement direction. The operator can adjust the spacing between adjacent combing units 211 in real time according to the warp diameter to ensure that the constraint stiffness of the warp within the combing section is moderate, avoiding warp swaying due to excessive gaps or scratching due to insufficient gaps. The combing units 211 have the function of adjusting warp tension. Combined with the tension adjustment mechanism 30, the spacing of each combing unit 21 along the transmission direction is adjusted synchronously, enabling the device to generate constraint force through overall displacement when the warp experiences transient offset or tension fluctuation.

[0023] The frame 10 can adopt a split-type splicing structure instead of an integral frame to adapt to the installation space of different models of braiding machines. The sliding method of the comb unit 211 can adopt a magnetic levitation guide rail instead of a mechanical guide rail to reduce frictional resistance. The comb section can use a ceramic guide ring instead of a metal ring to reduce warp wear.

[0024] In some embodiments, the tension adjustment mechanism 30 described above may employ, for example... Figure 1 , Figure 5 , Figure 6 The structure shown. See also Figure 1 , Figure 5 , Figure 6 The tension adjustment mechanism 30 includes two tension adjustment structures 31 and a rotation drive structure 32. The two tension adjustment structures 31 are spaced apart on the frame 10 along the warp direction, and each tension adjustment structure 31 is connected to one end of each combing unit 21 to synchronously adjust the distance between the combing units 21 located on both sides and the combing unit 21 located in the middle along the warp conveying direction. Each tension adjustment structure 31 is drive-connected to one end of each combing unit 21 to enable synchronous rotation of each combing unit 21, with the rotation axis arranged along the warp direction. The rotation drive structure 32 is drive-connected to both tension adjustment structures 31.

[0025] The tension adjustment mechanism 30 employs two tension adjustment structures 31 spaced apart along the warp direction, each connected to both ends of the combing unit 21. By synchronously adjusting the spacing between the combing units 21 on both sides and the middle combing unit 21, bidirectional symmetrical control of the warp tension is achieved, avoiding warp skewing caused by unilateral adjustment. The two tension adjustment structures 31 are spaced apart along the warp direction, forming a stable mechanical transmission framework to ensure that each combing unit 21 maintains parallel movement during adjustment, preventing warp twisting due to uneven force. Each tension adjustment structure 31 is driven to one end of each combing unit 21, allowing each combing unit 21 to rotate synchronously with its rotation axis set along the warp direction. This design allows the combing unit 21 to adjust the spacing while simultaneously fine-tuning the angle of the combing section by rotation, compensating for angular deviations during warp transport and improving the straightness of the warp arrangement.

[0026] The synchronous rotation design ensures that the combing units 21 maintain consistent orientation of each comb section during spacing adjustment, preventing changes in the friction direction between the warp and comb sections due to angle variations and reducing damage to the warp surface. The spaced arrangement of the two tension adjustment structures 31 creates redundant mechanical support, so that if one adjustment structure fails, the other can still maintain basic tension control functions, improving the reliability of the device.

[0027] In some embodiments, the tension adjustment structure 31 described above can be as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 The structure shown. See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6The tension adjustment structure 31 includes: a tension adjustment frame 311, a driving gear 312, a sliding gear 313, two sliding structures 314, two driven gears 315, and a tensioning belt 316. The tension adjustment frame 311 is arranged along the warp transmission direction and has an adjustment cavity extending along the interval direction of each warp. The driving gear 312 is rotatably disposed within the adjustment cavity, with its rotation axis arranged along the interval direction of each warp. One end of the driving gear 312 is connected to the power output end of the rotation drive structure 32, and the driving gear 312 is fixedly connected to the comb unit 21 located in the middle. The sliding gear 313 is slidably disposed on the driving gear 312 along the interval direction of each warp and rotates synchronously with the driving gear 312. Two sliding structures 314 are arranged annularly at intervals along the axis of the driving gear 312 and are slidably disposed within the adjusting cavity along the warp conveying direction. The two sliding structures 314 move relative to or away from each other when the driving gear 312 rotates. One end of each sliding structure 314 has a rack portion that meshes with the sliding gear 313, and the other end of each sliding structure 314 extends away from the sliding gear 313. Two driven gears 315 are arranged corresponding to the two sliding structures 314, and each driven gear 315 is rotatably disposed on the extended end of the corresponding sliding structure 314. The two driven gears 315 are fixedly connected to two combing units 21 located at both ends. A tensioning belt 316 is wound around the outside of the driving gear 312 and the two driven gears 315.

[0028] The tension adjusting frame 311 houses the driving gear 312, sliding gear 313, sliding structure 314, and driven gear 315, forming a closed power transmission space. This prevents external dust and fibers from interfering with gear meshing and extends the service life of the mechanism. The driving gear 312 is rotatably mounted in the adjusting cavity with its rotation axis along the warp direction and is fixedly connected to the intermediate combing unit 21, ensuring direct power transmission to the core combing unit 21 and reducing transmission losses. The sliding gear 313 is slidably mounted on the driving gear 312 along the warp direction and rotates synchronously with it. By sliding and changing its meshing position with the sliding rack 3141, the displacement of the driven gear 315 is adjusted. This structure converts rotational motion into linear motion, resulting in high transmission efficiency and precise positioning. Two sliding structures 314 are arranged annularly at intervals along the axis of the driving gear 312, sliding along the warp conveying direction. They mesh with the sliding gear 313 through the rack section, converting the rotation of the sliding gear 313 into its own linear sliding, which in turn drives the driven gear 315 to move, realizing the adjustment of the spacing between the two side combing units 21 and the middle combing unit 21. The driven gear 315 is fixedly connected to the combing unit 21, and a tension belt 316 is wrapped around the outside of the driving gear 312 and the driven gear 315 to form a synchronous transmission link, ensuring that the adjustment actions of the three combing units 21 are completely synchronized.

[0029] The adjustment chamber can adopt a split cover structure for easy maintenance of internal components. The sliding fit between the drive gear 312 and the sliding gear 313 can be achieved using a splined shaft instead of a flat key, enhancing torque transmission capability. The sliding structure 314 can be replaced by a ball screw instead of a rack structure, improving transmission accuracy. The tension belt 316 can be replaced by a synchronous belt instead of a flat belt to prevent slippage.

[0030] In some embodiments, the sliding structure 314 described above can be as follows: Figures 1 to 3 and Figure 5 The structure shown. See also Figures 1 to 3 and Figure 5 The sliding structure 314 includes a sliding rack 3141 and a sliding frame 3142. The sliding rack 3141 is arranged along the warp conveying direction, with one end meshing with the sliding gear 313, and the other end extending outward and away from the sliding gear 313 along the warp conveying direction. The sliding rack 3141 is a rack portion. The sliding frame 3142 is disposed on the extended end of the sliding rack 3141, and the sliding frame 3142 is used for rotatably connecting to the corresponding driven gear 315.

[0031] The linear movement of the rack drives the displacement of the sliding frame 3142. This structure is simple and compact, and its efficiency in converting rotational motion into linear motion is higher than that of cam or linkage mechanisms. The sliding frame 3142 is located at the extended end of the sliding rack 3141 and is used for rotational connection with the driven gear 315. This allows the position of the driven gear 315 to be adjusted synchronously with the sliding frame 3142, ensuring that the change in the distance between the driven gear 315 and the driving gear 312 perfectly matches the distance adjustment requirements of the comb unit 21.

[0032] The extended end design of the sliding rack 3141 shortens the connection distance between the driven gear 315 and the outside of the adjusting cavity, reducing the transmission chain length and lowering accumulated errors. The structural strength of the sliding bracket 3142 directly affects the positioning accuracy of the driven gear 315; the integrated casting process avoids gear misalignment caused by welding deformation. The meshing clearance between the sliding rack 3141 and the sliding gear 313 can be compensated by adjusting the axial position of the sliding gear 313, ensuring backlash-free transmission.

[0033] The sliding rack 3141 can use a helical rack instead of a straight rack to reduce meshing impact. The sliding frame 3142 can use a hollow structure to reduce weight and reduce the effect of inertia. The connection between the sliding rack 3141 and the sliding frame 3142 can use pin positioning instead of bolt fixing to improve connection rigidity. The tooth surface of the sliding rack 3141 can be nitrided to enhance wear resistance.

[0034] In some embodiments, the tension band 316 may be adopted as follows: Figures 1 to 3 and Figure 5 The structure shown. See also Figures 1 to 3 and Figure 5The tension belt 316 has multiple contact engagement sections and multiple tension compensation sections, which are spaced apart. Each contact engagement section meshes with either the driving gear 312 or the driven gear 315. The tension compensation sections are used to compensate for tension changes when the distance between the driven gear 315 and the driving gear 312 changes.

[0035] The tension belt is equipped with multiple contact engagement sections and tension compensation sections. The contact engagement sections mesh with the driving gear 312 or the driven gear 315 to ensure reliable power transmission and prevent slippage. The tension compensation sections elastically deform when the distance between the driven gear 315 and the driving gear 312 changes, absorbing the length changes caused by the distance adjustment and maintaining a constant tension in the tension belt 316 to prevent transmission failure caused by slackness or excessive tightness.

[0036] The elastic deformation characteristics of the tension compensation section can buffer the impact of warp tension fluctuations on the transmission system and prevent gear overload. The spaced arrangement of multiple contact meshing sections disperses meshing stress and extends the service life of the tension belt 316. The material selection of the tension compensation section (such as a rubber and fiber composite layer) can balance elasticity and wear resistance, making it suitable for high-frequency reciprocating motion scenarios.

[0037] In some embodiments, the sliding gear 313 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 There are two sliding gears 313, which are arranged on both sides of the driving gear 312 along the interval direction of each meridian. There are two sliding racks 3141, which are arranged in a one-to-one correspondence with the two sliding gears 313.

[0038] The drive gear 312 is provided with guide posts 3121 on both sides along the interval direction of each meridian for sliding gear 313 to slide. When each sliding gear 313 is close to the drive gear 312, it meshes with the corresponding sliding rack 3141. When each sliding gear 313 is far away from the drive gear 312, it disengages from the corresponding sliding rack 3141.

[0039] Two sliding gears 313 are arranged on both sides of the driving gear 312 along the warp direction, and two corresponding sliding racks 3141 are provided to form a symmetrical transmission structure. This ensures that the displacement of the driven gears 315 on both sides is completely consistent, guaranteeing that the three combing units 21 remain parallel and preventing warp skewing due to uneven force. Guide posts 3121 are provided on both sides of the driving gear 312 for the sliding gears 313 to slide. The cylindrical surface of the guide posts 3121 mates with the inner hole of the sliding gears 313, limiting the radial runout of the sliding gears 313 and ensuring meshing accuracy. When the sliding gears 313 are close to the driving gear 312, they mesh with the sliding racks 3141; when they are far away, they disengage. This clutch design allows the transmission to be disconnected without adjusting the tension, reducing unnecessary frictional losses.

[0040] The symmetrical transmission structure balances the lateral forces during the adjustment process, preventing deformation of the tension adjustment frame 311 due to uneven force. The surface roughness of the guide post 3121 affects the smoothness of the sliding gear 313; mirror finishing can reduce the coefficient of friction. The engagement and disengagement design of the sliding gear 313 and the sliding rack 3141 enables an "adjustment-locking" function. After adjustment, the gears disengage, and the positioning accuracy of the gears maintains the position of the comb unit 21, eliminating the need for an additional locking mechanism.

[0041] The guide post 3121 can be hollow to reduce weight. A self-lubricating bearing can be installed in the inner bore of the sliding gear 313 to reduce wear. The meshing end of the sliding rack 3141 can be chamfered to facilitate engagement of the sliding gear 313. Synchronous sliding of the two sliding gears 313 can be achieved through a linkage rod to ensure consistent operation.

[0042] In some embodiments, the warp combing device for a photovoltaic wire mesh weaving machine described above can be employed as follows: Figure 1 The structure shown. See also Figure 1 The warp combing device for photovoltaic wire mesh weaving machine also includes a tension feedback module. The tension feedback module is in contact with the warp and is used to detect the tension value of the warp in real time. Based on the tension value, the start, stop and speed of the rotation drive structure 32 are controlled.

[0043] The tension feedback module comes into contact with the warp threads, detects the warp tension value in real time, and feeds the signal back to the control system of the rotation drive structure 32, forming a closed-loop control circuit to achieve automatic tension adjustment. When the warp tension deviates from the preset range, the system automatically starts the rotation drive structure 32 to adjust the spacing of the combing units 21, without manual intervention, thus improving the adjustment response speed and accuracy.

[0044] The contact method of the tension feedback module (such as using rollers or sliders) can reduce friction with the warp yarns and avoid damage to them. The processing algorithm of the feedback signal can filter out instantaneous interference (such as warp yarn jitter) and prevent erroneous adjustments. Closed-loop control can achieve dynamic tension balance, and the system can automatically adapt even if changes in warp yarn material or ambient temperature cause changes in tension characteristics.

[0045] The tension feedback module can use a piezoelectric sensor instead of a strain gauge to improve sensitivity. The contact component can be made of ceramic to reduce electrostatic adsorption. The control system can use a PLC instead of a microcontroller to enhance expandability. Feedback signals can be transmitted wirelessly instead of wired connections, simplifying wiring.

[0046] In some embodiments, the comb unit 21 described above may employ, as follows: Figure 1 , Figure 4 , Figure 5 , Figure 6 The structure shown. See also Figure 1 , Figure 4 , Figure 5 , Figure 6 Each combing unit 21 also includes a connecting shaft 212, which is arranged along the interval direction of each warp. Each end of the connecting shaft 212 is connected to two driving gears 312 or two corresponding driven gears 315. Each connecting shaft 212 is slidably connected to each corresponding combing unit 211.

[0047] Each combing unit 21 is equipped with a connecting shaft 212 arranged along the warp direction, with two driving gears 312 or corresponding driven gears 315 connected to its two ends respectively. This provides a sliding support reference for the combing unit 211, ensuring that each combing unit 211 maintains coaxiality when adjusting the spacing and avoiding warp offset due to unstable support. The rigidity of the connecting shaft 212 directly affects the positioning accuracy of the combing unit 211, and it is made of high-strength alloy steel to resist bending deformation caused by warp tension.

[0048] The rotation of the connecting shaft 212 drives the comb unit 211 to rotate synchronously, ensuring that the comb section is always perpendicular to the warp conveying direction, thus reducing the frictional resistance between the warp and the comb section. The surface treatment of the connecting shaft 212 (such as hard chrome plating) can reduce the sliding friction coefficient of the comb unit 211 and extend its service life. The connection method at both ends of the connecting shaft 212 (such as key connection or expansion sleeve) allows for easy disassembly and assembly, facilitating maintenance.

[0049] The connecting shaft 212 can be hollow to reduce weight. A PTFE coating can be applied to the surface to reduce friction. A quick-locking mechanism can be used at both ends to improve assembly and disassembly efficiency. Multiple connecting shafts 212 can be arranged in parallel to enhance support stability.

[0050] In some embodiments, the comb unit 211 described above may be as follows: Figure 1 , Figure 4 The structure shown. See also Figure 1 , Figure 4 Each combing unit 211 includes a sliding bushing 2111, a combing block 2112, and a combing wheel 2113. The sliding bushing 2111 is slidably mounted on the connecting shaft 212. One end of the combing block 2112 is fixed to the sliding bushing 2111, and the other end extends radially along the connecting shaft 212. The combing wheel 2113 is rotatably mounted on the extended end of the combing block 2112, with its rotation axis parallel to and spaced apart from the axis of the connecting shaft 212. The combing wheel 2113 is provided with a combing groove for accommodating the warp threads, and an anti-detachment ring 21131 is fitted at the combing groove. The combing wheel 2113 and the anti-detachment ring 21131 together constitute the combing part.

[0051] The combing unit 211 is slidably mounted on the connecting shaft 212 using a sliding bushing 2111, allowing for spacing adjustment. One end of the combing block 2112 is fixed to the sliding bushing 2111, while the other end extends radially, forming a cantilever support structure that positions the combing wheel 2113 on the warp path. The combing wheel 2113 is rotatably mounted with its axis of rotation parallel to the connecting shaft 212. The warp threads are accommodated in the combing groove and secured by an anti-detachment ring 21131. This structure converts sliding friction into rolling friction, significantly reducing warp thread transport resistance and minimizing wear. The anti-detachment ring 21131 prevents the warp threads from slipping out of the combing groove, ensuring reliable combing.

[0052] The rotation of the combing wheel 2113 releases torsional stress during warp yarn transport, preventing warp yarn from tangling. The cross-sectional shape of the combing groove (such as U-shaped or V-shaped) can accommodate warp yarns of different diameters. The material of the anti-detachment buckle 21131 (such as elastic plastic) can buffer warp yarn vibration and reduce impact. The damping between the sliding bushing 2111 and the connecting shaft 212 prevents the comb unit 211 from spontaneously sliding due to warp yarn vibration.

[0053] The sliding bushing 2111 can be made of copper alloy instead of steel to improve wear resistance. The combing wheel 2113 can be made of ceramic material to reduce static electricity. The surface of the combing groove can be polished to reduce friction. The anti-loosening buckle 21131 can be magnetic instead of clip-on for easier threading.

[0054] In some embodiments, the aforementioned sliding bushing 2111 can be adopted as follows: Figure 4 The structure shown. See also Figure 4 Damping is provided between the sliding bushing 2111 and the connecting shaft 212, and damping is provided between the combing wheel 2113 and the combing block 2112.

[0055] Damping is provided between the sliding bushing 2111 and the connecting shaft 212, and between the combing wheel 2113 and the combing block 2112. The former prevents the combing unit 211 from sliding unexpectedly under warp vibration or tension fluctuations, maintaining spacing stability. The latter prevents the combing wheel 2113 from shifting its rotation angle under warp impact, ensuring that the combing groove is always aligned with the warp conveying direction. The damping gives the combing unit 211 a "positioning-floating" characteristic, allowing it to slide smoothly during adjustment and remain stable in the working position.

[0056] The damping properties absorb high-frequency vibrations of the warp threads, reducing noise. The viscoelasticity of the damping material buffers the impact between the warp and comb sections, extending component life. The damping force can be adjusted by changing the fit clearance or material hardness to suit different tension scenarios.

[0057] The above are merely preferred embodiments of the present invention and are 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.
