Description

Technical Field

[0001] This application relates to the field of metal wire mesh processing, and in particular to a double warp beam weaving machine for processing special metal wire mesh. Background Technology

[0002] Currently, wire mesh weaving technology is widely used in industrial filtration, protection, and decoration, playing a vital role in industrial production and daily life. With the continuous development of various industries, the demand for wire mesh is increasing, and the requirements for its quality and performance are also becoming more stringent. The weaving quality and efficiency of wire mesh directly affect the quality and production efficiency of related products. Therefore, the development of wire mesh weaving technology is of great significance to promoting the development of related industries.

[0003] In existing technologies, conventional wire mesh weaving machines primarily employ a single warp beam design to achieve the weaving of wire mesh. The warp threads form a shed through the lifting and lowering of the heald frame, and then the weft is inserted via a rapier or air jet to complete the weaving process. However, the single warp beam design can only provide warp threads of a single thickness, failing to meet the needs of mixed-thickness weaving and making it difficult to achieve mixed-thickness weaving. Summary of the Invention

[0004] To meet the requirements of mixed weaving of thick and thin warp yarns, and to improve weaving efficiency and precision, this application provides a double warp beam weaving machine for special metal wire mesh processing.

[0005] The special metal wire mesh processing double warp beam weaving machine provided in this application adopts the following technical solution: A special metal wire mesh processing double warp beam weaving machine includes a frame, a double warp beam assembly, a heald frame assembly, a weft insertion assembly, a weft insertion assembly, and a protective lighting assembly; The dual warp shaft assembly includes a coarse warp shaft and a fine warp shaft rotatably connected to the frame, a gearbox respectively disposed at the ends of the coarse warp shaft and the fine warp shaft, and a drive motor connected to the input end of the gearbox; The heald frame assembly includes a support frame fixed to the frame, multiple heald frames slidably connected vertically to the support frame, and a lifting component for independently driving each heald frame to move up and down. The weft insertion assembly includes two rapiers that can move intermittently in opposite directions. The weft insertion assembly includes a conjugate cam box and a reed, wherein the conjugate cam box is connected to the reed in a transmission manner to drive the reed to reciprocate. The warp threads of the coarse and fine warp beams alternately pass through the heald frame to form a double-layer warp structure, and the reed presses the weft threads into the shed formed by the double-layer warp by oscillating.

[0006] By adopting the above technical solution, the coarse and fine warp beams in the double warp beam assembly rotate under the drive of the motor and gearbox, causing the warp threads of the coarse and fine warp beams to alternately pass through the heald frame to form a double-layer warp structure. This achieves mixed weaving of coarse and fine warp threads, broadens the application range of wire mesh, and can meet the weaving requirements of different strengths or functions. The lifting components in the heald frame assembly can independently drive each heald frame to move up and down, thereby precisely controlling the layering of the warp threads and preparing for the introduction of the weft threads. The two rapiers of the weft insertion assembly can move back and forth intermittently in opposite directions, which can efficiently complete the introduction of the weft threads, realizing the "one-top-one-hook, one-feed-one-connection" of the weft threads. The conjugate cam box of the weft insertion assembly transmits power to the reed, driving the reed to swing back and forth, pressing the weft threads into the shed formed by the double-layer warp threads, ensuring accurate weft thread connection. The protective lighting component improves the operating environment and facilitates real-time monitoring of weaving quality. The coordinated work of all components realizes mixed weaving of coarse and fine warp threads, while improving weaving efficiency and precision.

[0007] Optionally, the lifting component includes multiple servo multi-arms, each corresponding to a heald frame. The multiple servo multi-arms are divided into two groups and respectively disposed on both sides of the frame. The servo multi-arms are connected to the corresponding heald frames to drive them to move up and down.

[0008] By adopting the above technical solution, when the equipment is running, the servo motor in the servo multi-arm starts, and its output shaft drives the drive block to rotate. The drive block drives the swing arm to swing through the first drive rod connected to the rotation. The swing arm then drives the corresponding heald frame to move up and down on the support frame fixed to the frame through the second drive rod. This achieves individual and precise control of each heald frame, so that each heald frame moves up and down according to the required timing and amplitude. This ensures that the warp threads can be accurately layered to form a stable double-layer warp structure. At the same time, the precise layering is conducive to the smooth passage of the weft threads in the subsequent weft insertion process, ensuring the stability of the weft thread connection and improving the accuracy and quality of weaving.

[0009] Optionally, the servo multi-arm includes a servo motor fixed on the frame, a drive block fixedly sleeved on the output shaft of the servo motor, a first drive rod rotatably connected to the drive block, and a swing arm rotatably connected to the frame; one end of the swing arm is hinged to the first drive rod, and the other end is hinged to the heald frame with a second drive rod.

[0010] By adopting the above technical solution, the servo motor drives the drive block to rotate, and the drive block drives the first drive rod connected to it to move. The movement of the first drive rod causes the swing arm, which is hinged to it, to swing around its rotation point on the frame. The swing arm swings and drives the heald frame to move up and down through the second drive rod, thereby realizing independent and precise control of the heald frame. Each servo multi-arm drives the corresponding heald frame to rise and fall independently, ensuring the stability of warp layering and weft weaving. The position of the heald frame can be precisely adjusted according to weaving requirements, so that the weaving machine can adapt to different weaving processes and pattern requirements, thus broadening its application range.

[0011] Optionally, the weft insertion assembly further includes a power motor rotatably connected to the frame, a gear fixedly sleeved on the output shaft of the power motor, a rack slidably connected to the frame and meshing with the gear, and a limit adjustment module for fine-tuning and limiting the rapier's movement trajectory laterally and vertically, wherein the rapier is fixed to the rack.

[0012] By adopting the above technical solution, the rotation of the power motor drives the gear fixed on its output shaft to rotate. The gear meshes with the rack, causing the rack to slide on the frame. Since the rapier is fixed to the rack, it drives the rapier to move intermittently in opposite directions, realizing the weft insertion action. At the same time, the lateral and vertical fine-tuning and limit functions of the limit adjustment module can ensure the accuracy and stability of the rapier during movement, reduce rapier running deviation, and avoid problems such as inaccurate weft thread splicing or thread breakage caused by inaccurate rapier position. Moreover, when the weaving machine parts may wear or loosen after long-term use, causing deviation in the rapier position, the rapier movement trajectory can be adjusted in time to ensure the continuous and stable operation of the weaving machine, improving the overall reliability and service life of the weaving machine.

[0013] Optionally, the limit adjustment module includes a vertical plate fixed to the frame, a horizontal plate fixed to the top of the vertical plate, and a support seat disposed above the rack; Two upper guide limiting wheels are rotatably connected to the support base, abutting against the top of the rack and adjustable in position by moving up and down. Upper limit plates are fixed on both sides of the upper guide limiting wheels in the width direction, and the upper limit plates are engaged with both sides of the rack in the width direction. A lower guide wheel is provided below the rack, and lower limit plates are fixed on both sides of the lower guide wheel in the width direction. The lower limit plates are snapped onto both sides of the rack in the width direction. An adjustment seat is fixed on the frame. The adjustment seat has an adjustment groove in the vertical direction. A support rod is slidably connected in the vertical direction inside the adjustment seat. The support rod cannot move relative to the adjustment seat in the lateral direction. The end of the support rod has a threaded part, and the threaded part of the support rod is threadedly connected to a locking nut. One side of the locking nut is tightly fitted with the adjustment seat to lock the upper and lower positions of the support rod. The lower guide wheel is sleeved on the outside of the support rod and can slide and rotate along the length direction of the support rod.

[0014] By adopting the above technical solution, the limit adjustment module features a specific layout for the vertical plate, horizontal plate, and support base. The upper guide limit wheel abuts against the top of the rack and can be adjusted by changing its vertical position. The upper limit plate engages with the racks on both sides, preventing deviation in the width direction when the rack moves laterally, thus ensuring the lateral stability, accuracy, and straightness of the rack's movement path. The lower guide limit wheel cooperates with the adjustment base fixed on the frame. The lower guide limit wheel itself can slide and rotate along the support rod. When height adjustment is required, the locking nut is loosened, and the lower guide limit wheel can be adjusted in height by adjusting the position of the support rod within the adjustment groove. Once the position is determined, the locking nut is tightened to lock it in place. This allows for flexible adjustment of the lower guide limit wheel's height according to actual needs, thereby flexibly adjusting the positions of the rack and scissor, making the limit function more flexible and precise. The upper and lower guide limit wheels work together to limit the rack from both sides, restricting its lateral and longitudinal freedom throughout the operation. This improves the smoothness and safety of the rack transmission. When used in conjunction with other components of the weft insertion assembly, such as the power motor and gears, it ensures that the rapier moves precisely along the preset trajectory, guaranteeing the synchronization and accuracy of the weft insertion action, avoiding weft insertion deviations and errors, and reducing the scrap rate.

[0015] Optionally, a plurality of lateral adjusting bolts are provided between the upright plate and the support base, wherein the lateral adjusting bolts are threadedly connected to the support base, and the upright plate is provided with a vertical waist-shaped groove adapted to the lateral adjusting bolts, wherein the lateral adjusting bolts can move up and down within the vertical waist-shaped grooves; a lateral set bolt is threadedly connected to the upright plate, and one end of the lateral set bolt abuts against the support base. Multiple vertical adjusting bolts are provided between the horizontal plate and the support base. The vertical adjusting bolts are threadedly connected to the support base. A transverse waist-shaped groove adapted to the vertical adjusting bolt is provided on the horizontal plate along the horizontal direction. The vertical adjusting bolt can move laterally within the transverse waist-shaped groove. A vertical set bolt is threadedly connected to the horizontal plate. One end of the vertical set bolt abuts against the support base.

[0016] By adopting the above technical solution, multiple lateral adjusting bolts are threadedly connected to the support base between the upright plate and the support base. The vertical slot on the upright plate is adapted to accommodate these lateral adjusting bolts, allowing them to move up and down within the slot. Combined with the threaded lateral set bolts on the upright plate, which abut against the support base, the lateral position of the support base can be finely adjusted and locked. When adjusting the lateral position of the support base, first loosen the lateral set bolts; the lateral adjusting bolts can then slide within the vertical slots to change the lateral position of the support base. After adjustment, tighten the lateral set bolts to lock the position. This allows for precise control of the support base's lateral position, thereby fine-tuning the lateral movement trajectory of the rack and the fixed rapier, ensuring the rapier's lateral movement accuracy and preventing deviations in its lateral movement. Multiple vertical adjusting bolts are threadedly connected to the support base between the horizontal plate and the support base. The horizontal slot on the horizontal plate is adapted to accommodate these vertical adjusting bolts, allowing them to move laterally within the slot. These bolts, along with the threaded vertical set bolts on the horizontal plate, abut against the support base, enabling fine-tuning and locking of the support base's vertical position. When adjusting the support base's vertical position, first loosen the vertical set bolts. The vertical adjusting bolts can then slide within the horizontal slots to change the support base's vertical position. After adjustment, tighten the vertical set bolts to lock the position. This allows for precise control of the support base's vertical position, enabling fine-tuning of the vertical movement trajectory of the rack and the fixed sword shaft, ensuring the sword shaft's vertical movement accuracy and preventing deviations in its vertical motion.

[0017] Optionally, guard plates are fixed on both sides of the rack in the width direction, and a preset distance is spaced between the guard plates and the lower guide limit wheel so that the toothed side of the rack is separated from the lower guide limit wheel.

[0018] By adopting the above technical solution, guard plates are fixed on both sides of the rack in the width direction, and a preset distance is maintained between the guard plates and the lower guide limit wheel. This allows the toothed side of the rack to be separated from the lower guide limit wheel. When the rack and gear mesh and reciprocate, the toothed side of the rack will not directly contact the lower guide limit wheel, reducing friction and wear between them, reducing heat and noise generated by friction, and making the rack move more smoothly, thus extending the service life of the rack and the lower guide limit wheel.

[0019] Optionally, the weft insertion assembly further includes: A current transformer is installed on the drive shaft of the conjugate cam box and is used to detect the real-time rotation angle of the drive shaft of the conjugate cam box. The controller, electrically connected to the current transformer, is configured to: receive a real-time rotation angle signal sent by the current transformer; determine the target swing stroke of the reed at the current angle according to a pre-stored mapping relationship between the rotation angle of the conjugate cam box drive shaft and the target position of the reed; and generate a control signal based on the real-time rotation angle and the target swing stroke to adjust the actual swing stroke of the reed.

[0020] By adopting the above technical solution, the current transformer is installed on the conjugate cam box drive shaft, which can accurately detect the real-time rotation angle of the conjugate cam box drive shaft. The detected real-time rotation angle signal is sent to the controller electrically connected to it. Based on the pre-stored mapping relationship between the rotation angle of the conjugate cam box drive shaft and the target position of the reed, the controller calculates the target swing stroke that the reed should reach at the current angle. Based on the data of the real-time rotation angle and the target swing stroke, the controller generates a precise control signal. This control signal can dynamically adjust the actual swing stroke of the reed, ensuring that the reed swings at the appropriate time and position, accurately pressing the weft yarn into the shed formed by the double-layer warp yarns. Compared with the traditional weft-beating structure, precise control optimizes the motion conversion efficiency of the weft-beating structure, greatly improves the weaving speed, and ensures the accuracy of weft yarn joining.

[0021] Optionally, the protective lighting assembly includes an acrylic shield and a lighting lamp embedded in the inner surface of the shield, the acrylic shield covering the front, middle, rear and lower parts of the frame.

[0022] By adopting the above technical solution, the acrylic cover in the protective lighting component covers the front, middle, rear and lower parts of the frame, which can effectively prevent dust from entering the inside of the weaving machine, while improving the safety of the workers. The lighting lamp embedded in the inner surface of the cover can provide sufficient lighting for the operators, making it easy for them to observe the operating status of the weaving machine, the weaving of warp and weft threads, and the display of various parameters, so as to promptly detect problems such as broken threads and inaccurate weft thread splicing during the weaving process and ensure the weaving quality.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The dual warp beam assembly, heald frame assembly, beat-up assembly, weft insertion assembly, and protective lighting assembly work together to achieve mixed weaving of thick and thin warp threads. Compared with traditional single warp beam weaving machines that can only use a single thickness of warp thread, the mixed weaving method can meet the weaving requirements of different strengths or functions, thereby broadening the application range of metal wire mesh in multiple fields such as industrial filtration, protection, and decoration. The individual and precise control of each heald frame allows each heald frame to rise and fall according to the required sequence and amplitude, ensuring that the warp threads can be accurately layered to form a stable double-layer warp structure. At the same time, the precise layering is conducive to the smooth passage of the weft threads during the subsequent weft insertion process, ensuring the stability of the weft thread connection and improving the accuracy and quality of weaving. Each servo multi-arm independently drives the corresponding heald frame lifting and lowering, ensuring the stability of warp layering and weft thread docking. It can precisely adjust the position of the heald frame according to weaving needs, enabling the weaving machine to adapt to different weaving processes and pattern requirements, thus broadening its application range. When the parts of the mesh weaving machine may wear or loosen after a long period of use, causing the position of the rapier to deviate, the movement trajectory of the rapier can be adjusted in time to ensure the continuous and stable operation of the mesh weaving machine and improve the overall reliability and service life of the mesh weaving machine. The upper and lower guide limit wheels work together to limit the rack from both sides, restricting its lateral and longitudinal freedom throughout the operation. This improves the smoothness and safety of the rack transmission. When used in conjunction with other components of the weft insertion assembly, such as the power motor and gears, it ensures that the rapier moves precisely along the preset trajectory, guaranteeing the synchronization and accuracy of the weft insertion action, avoiding weft insertion deviations and errors, and reducing the scrap rate.

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses a double-warp beam weaving machine for processing special metal wire mesh. (Refer to...) Figure 1 and Figure 2 The special metal wire mesh processing double warp beam weaving machine includes a frame 1, a double warp beam assembly 2 mounted on the frame 1, a heald frame assembly 3, a weft insertion assembly 4, a weft insertion assembly 5, and a protective lighting assembly 6. These components work together to complete the weaving of the special metal wire mesh, achieving mixed weaving of thick and thin warp threads, broadening the application range of metal wire mesh, and improving weaving efficiency and precision.

[0028] Specifically, refer to Figure 1 and Figure 2The dual warp beam assembly 2 includes a coarse warp beam 21 and a fine warp beam 22 rotatably connected to the frame 1. Both the coarse and fine warp beams 21 and 22 have a gearbox 23 at their ends, with the input end of the gearbox 23 connected to a drive motor 24. The coarse and fine warp beams 21 and 22 are made of high-strength metal and are rotatably connected to the frame 1 via bearings, reducing rotational friction and ensuring smoother rotation. The drive motor 24 is a stepper motor, which allows for more precise control of the shaft's rotation angle and speed. The drive motor 24 is connected to the gearbox 23 via a coupling to ensure efficient power transmission. The drive motor 24 drives the coarse and fine warp beams 21 and 22 to rotate through the gearbox 23, providing warp yarns of different thicknesses for weaving. This enables mixed weaving of coarse and fine warp yarns and allows adjustments to be made according to the warp yarn thickness and tension requirements of different fabrics, producing metal mesh of various specifications.

[0029] Specifically, refer to Figure 3 and Figure 4 The heald frame assembly 3 includes a support frame 31 fixed on the frame 1, multiple heald frames 32 that can slide vertically along the support frame 31, and a lifting component 33 that can independently drive each heald frame 32 to move up and down. The heald frame 32 is made of a metal frame and has a threading hole inside for passing warp threads. It is vertically slidably connected to the support frame 31 through a guide rail slider structure 34 to ensure smooth up and down movement.

[0030] Reference Figure 3 and Figure 4 The lifting component 33 includes multiple servo multi-arms 331, each corresponding to a multiple heald frames 32. The servo multi-arms 331 are arranged in two groups on both sides of the frame 1 and connected to the corresponding heald frames 32 to drive them to move up and down. Each servo multi-arm 331 includes a servo motor 3311 fixed on the frame 1, a drive block 3312 fixedly sleeved on the output shaft of the servo motor 3311, a first drive rod 3313 rotatably connected to the drive block 3312, and a swing arm 3314 rotatably connected to the frame 1. One end of the swing arm 3314 is hinged to the first drive rod 3313, and the other end is hinged to the heald frame 32 through a second drive rod 3315.

[0031] When the servo motor 3311 is working, its output shaft drives the drive block 3312 to rotate. The drive block 3312 drives the first drive rod 3313 to move, which in turn causes the swing arm 3314 to swing. The swing arm 3314 then drives the heald frame 32 to move up and down via the second drive rod 3315. Since each heald frame 32 is controlled by an independent servo multi-arm 331, it can accurately achieve warp layering, ensure stable weft thread docking, and meet the requirements for precise control of the lifting sequence and height of each heald frame 32 when weaving complex patterned wire mesh.

[0032] Specifically, refer to Figure 5 and Figure 6The weft insertion assembly 5 has two rapiers 51 that can move intermittently in opposite directions, a power motor 52 rotatably connected to the frame 1, a gear 53 fixedly sleeved on the output shaft of the power motor 52, a rack 54 that can slide on the frame 1 and mesh with the gear 53, and a limit adjustment module 55 for making lateral and vertical fine adjustments and limiting the movement trajectory of the rapiers 51. The rapiers 51 and the rack 54 are fixed.

[0033] Reference Figure 5 and Figure 7 The limit adjustment module 55 includes a vertical plate 551 fixed on the frame 1, a horizontal plate 5511 fixed on the top of the vertical plate 551, and a support base 552 disposed above the rack 54. Two upper guide limit wheels 553 are rotatably connected to the support base 552, abutting against the top of the rack 54 and adjustable in position by vertical movement. Upper limit plates 5531 are fixed to both sides of the upper guide limit wheels 553 in the width direction, engaging with both sides of the rack 54 in the width direction. A lower guide limit wheel 554 is provided below the rack 54, with lower limit plates 5541 fixed to both sides in the width direction, engaging with both sides of the rack 54 in the width direction. An adjusting seat 555 is fixed on the frame 1, and the adjusting seat 555 has an adjusting groove 5551 opened vertically. A support rod 556 is slidably connected vertically inside the adjusting groove 5551. The support rod 556 cannot move relative to the adjusting seat 555 in the lateral direction. The end of the support rod 556 is provided with a threaded part, and the threaded part of the support rod 556 is connected to a locking nut 5561. Tightening the locking nut 5561 can lock the upper and lower positions of the support rod 556. A lower guide limit wheel 554 is sleeved on the outside of the support rod 556 and can slide and rotate along its length.

[0034] There are multiple horizontal adjusting bolts 557 between the upright plate 551 and the support base 552. The horizontal adjusting bolts 557 are threadedly connected to the support base 552. The upright plate 551 has a vertical slot 5571 that matches the horizontal adjusting bolts 557. The horizontal adjusting bolts 557 can move up and down within the vertical slot 5571. A horizontal set bolt 5572 is threadedly connected to the upright plate 551. One end of the horizontal set bolt 5572 abuts against the support base 552. Multiple vertical adjusting bolts 558 are provided between the horizontal plate 5511 and the support base 552. The vertical adjusting bolts 558 are threadedly connected to the support base 552. A transverse waist-shaped groove 5581 adapted to the vertical adjusting bolts 558 is opened on the horizontal plate 5511 along the horizontal direction. The vertical adjusting bolts 558 can move laterally within the transverse waist-shaped groove 5581. A vertical set bolt 5582 is threadedly connected to the horizontal plate 5511. One end of the vertical set bolt 5582 abuts against the support base 552. Protective plates 541 are fixed on both sides of the rack 54 in the width direction. The protective plates 541 are spaced at a preset distance from the lower guide limit wheel 554 so that the toothed side of the rack 54 is separated from the lower guide limit wheel 554. When the rack 54 meshes with the gear 53 and reciprocates, the toothed side of the rack 54 will not directly contact the lower guide limit wheel 554, reducing friction and wear between the two.

[0035] When fine-tuning the vertical position of the rapier 51 is required, first loosen the vertical set bolt 5582 and lock nut 5561. Adjust the height of the upper and lower guide limit wheels 554 according to the vertical deviation. After adjustment, tighten the vertical set bolt 5582 and lock nut 5561 to lock the position. When fine-tuning the horizontal position of the rapier 51 is required, first loosen the horizontal set bolt 5572. Adjust the horizontal position of the upper and lower guide limit wheels 554 according to the horizontal deviation. After adjustment, tighten the horizontal set bolt 5572 to lock the position. The weft insertion assembly 5 drives the gear 53 to rotate via the power motor 52. The gear 53 meshes with the rack 54, causing the rack 54 to drive the rapier 51 to move intermittently in opposite directions to complete the weft insertion work. The limit adjustment module 55 can accurately adjust the movement trajectory of the rapier 51 to ensure the accuracy and stability of weft insertion and avoid inaccurate weft thread splicing or thread breakage due to deviation in the movement trajectory of the rapier 51.

[0036] Reference Figure 7 and Figure 8The weft insertion assembly 4 includes a conjugate cam box 41, a reed 42, a current transformer, and a controller. The conjugate cam box 41 is connected to the reed 42 via a drive mechanism, and its output end converts the rotational motion into the oscillating motion of the reed 42 through a connecting rod. The conjugate cam box 41 has high motion accuracy and stability, and the surface of the reed 42 is specially treated to reduce wear on the warp and weft threads. The current transformer is mounted on the drive shaft of the conjugate cam box 41 and can accurately detect its real-time rotation angle and transmit the signal to the controller. After receiving the signal, the controller determines the target oscillation stroke of the reed 42 at the current angle based on the pre-stored mapping relationship between the rotation angle of the drive shaft of the conjugate cam box 41 and the target position of the reed 42. Then, based on the real-time rotation angle and the target oscillation stroke, it generates a control signal to adjust the actual oscillation stroke of the reed 42. This optimizes the motion conversion efficiency of the weft insertion structure, improves the weaving speed, ensures accurate weft thread alignment, and meets the requirements of weft insertion accuracy and speed for weaving high-density metal wire mesh.

[0037] Reference Figure 8 The protective lighting component 6 consists of an acrylic cover and lighting fixtures embedded in the inner surface of the cover. The acrylic cover covers the front, middle, rear, and lower parts of the frame 1. The acrylic cover has high transparency, good impact resistance, and effectively prevents dust. The lighting fixtures are LED lights, which are energy-saving, bright, and have a long lifespan. The protective lighting component 6 improves the operating environment, allowing workers to easily monitor the weaving quality in real time in a bright and clean environment, and promptly detect and address problems such as warp breakage and inaccurate weft splicing.

[0038] The implementation principle of a double warp beam weaving machine for special metal wire mesh processing according to this application embodiment is as follows: Through the coordinated work of various components, the double warp beam weaving machine of this embodiment achieves mixed weaving of thick and thin warp threads, significantly broadening the application range of metal wire mesh. Multiple servo multi-arms 331 of the heald frame assembly 3 precisely control the lifting and lowering of the heald frame 32, ensuring the stability of warp layering and weft thread joining. Under the action of the limit adjustment module 55, the rapier 51 of the weft insertion assembly 5 achieves precise reciprocating movement in opposite directions, ensuring the accuracy and stability of weft insertion. The beat-up assembly 4, through the cooperation of a current inductor and a controller, optimizes the motion conversion efficiency of the beat-up structure, improving the weaving speed. Compared with existing single warp beam weaving machines, the weaving machine of this application has significantly improved in terms of weaving efficiency, accuracy, and applicability, and can meet the diverse needs of different industries for metal wire mesh.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
