Description

Technical Field

[0001] This invention relates to the field of wire mesh weaving mechanism technology, and particularly to a close-wound wire mesh weaving mechanism with freely adjustable weft spacing. Background Technology

[0002] The warp and weft mesh weaving machine is used to weave square grid-type metal mesh fences with orthogonal warp and weft. The raw materials can be galvanized wire, steel wire, plastic-coated wire, etc. It is mostly used in coal mine support fences, industrial isolation fences and other scenarios. The equipment can realize automatic wire feeding, weaving and mesh rolling.

[0003] Currently, traditional wire mesh weaving equipment mainly relies on conventional clamping structures to simply limit the warp and weft threads and mechanically wind them to complete the knotting operation during actual production. Existing equipment has a simple structural design and poor positioning accuracy, making it impossible to effectively pre-fix the warp ends before knotting and winding. This causes the warp threads to easily shift, wobble, and move during high-speed winding and twisting, resulting in quality defects such as misaligned knots, loose knots, and mesh deformation. The finished mesh has poor uniformity and low knot strength, seriously affecting the overall structure of the wire mesh fence. Strength and appearance quality; meanwhile, traditional weaving equipment has poor linkage between the various processes of wire feeding, positioning, knotting, and discharge, and lacks a dedicated precise limiting conveying structure, making it impossible to achieve integrated and continuous operation of wire picking, feeding, positioning, unloading, and discharge. The process connection is stuck, and the production efficiency is low. Therefore, existing wire mesh weaving equipment generally suffers from many technical defects such as unstable wire positioning, easy loosening of knots, poor consistency of finished products, and weak process continuity. Therefore, this application provides a weft spacing freely adjustable close-wound wire mesh weaving mechanism to meet the needs. Summary of the Invention

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up the edge twisting component and the knotting mechanism, not only can the two ends of the warp yarn body be wrapped and fixed, effectively preventing the warp yarn body from shifting or shaking during the knotting process, ensuring the stability and accuracy of the knotting operation, but the knotting mechanism is then used to tightly wrap the knotting yarn body to the intersection of the warp yarn body and the weft yarn body to form a tight and fixed knot, realizing a stable connection between the warp yarn body and the weft yarn body. Through the coordinated use of various structures, this device can quickly complete the automated conveying, cutting, positioning and knotting operations of the warp yarn body, the weft yarn body and the knotting yarn body. By pre-fixing the two ends of the warp yarn body before knotting, the problems of knotting misalignment, loose knots and mesh deformation are completely eliminated, greatly improving the weaving and forming accuracy. Relying on the limiting conveying structure of the pressure plate and the feeding plate, the entire process of taking out the yarn, feeding the yarn and unloading the material can be completed quickly. The operation is highly continuous and the production efficiency is high. Moreover, the weft yarn spacing can be quickly and freely adjusted, so that one machine can weave multiple types of mesh fences.

[0016] By incorporating pressure plates, feeding plates, and top warp and weft center columns within the device, it can precisely limit, guide, and position the intersecting warp and weft yarns, effectively restricting displacement deviations during the yarn weaving process and ensuring precise and constant warp and weft yarn intersection positions. Simultaneously, it can coordinate with the overall machine operation to quickly complete the yarn picking, feeding, positioning, and unloading processes, significantly improving the continuity and consistency of the weaving operation.

[0017] By incorporating a wire twisting head and a wire twisting motor within the device, the two ends of the warp yarn body can be pre-wound and fixed before knotting operations. This solves the problems of swaying, shifting, and loosening of the warp yarn body during high-speed knotting and winding, effectively improving the knotting accuracy, ensuring that each knot is evenly stressed and neatly formed, and significantly enhancing the overall flatness and weaving stability of the net.

[0018] By incorporating a knotting mechanism within the device, not only can the knotting wire body achieve bidirectional tight wrapping and knotting of the warp and weft wire bodies at their intersecting nodes, but the overall knotting process is also compact and highly automated. Specifically, the process involves: first, precisely feeding the warp and knotting wires into position; then, the weft winding motor drives the upper weft winding die to rotate, using the knotting wire cutter integrated into the upper die to simultaneously cut the knotting wires, while continuous rotation tightly wraps and fixes the knotting wires to the outside of the weft wires; finally, the warp winding motor operates independently to securely wrap and cover the knotting wires to the outside of the warp wires, thus fully realizing positioning, wire feeding, cutting, bidirectional wrapping, and knotting. The integrated automatic forming system is designed for standardized production. The core of this mechanism employs a synchronous and coordinated operation of wire cutting and winding, abandoning the traditional step-by-step process model. This significantly shortens the forming cycle of a single knot and substantially improves the overall weaving production rate. Simultaneously, the bidirectional layered winding structure ensures tight wrapping and even stress distribution at the knots, resulting in firmly secured knots that are not easily loosened, effectively guaranteeing the quality of the mesh fence weaving. Furthermore, the installation spacing can be freely adjusted by changing different installation and fixing methods, achieving stepless adjustment of the weft wire knot spacing. This adapts to different mesh sizes and density specifications, making the equipment highly versatile.

[0019] By incorporating a first mounting bracket, threaded column, connecting bracket, lower scraper, and upper scraper within the device, metal shavings generated during work can be automatically collected using magnetic adsorption. The conical slag collection structure automatically gathers and scrapes away the shavings, enabling continuous self-cleaning of the weaving station. This effectively prevents shavings from jamming gears, jamming wires, or wearing down the transmission structure, ensuring long-term continuous and stable operation of the equipment and reducing the frequency of downtime for cleaning.

[0020] By incorporating a conveying cylinder, a first connecting plate, and a third connecting plate within the device, not only can the magnetically shielding conveying cylinder prevent secondary magnetic adhesion of metal debris, ensuring smooth debris detachment and collection, but the elastic louver structure of the first and second connecting plates, in conjunction with the hook-and-loop mechanism of the third connecting plate, enables automatic opening and closing for unloading. Relying on the inherent toughness of the material, automatic springback reset is achieved, eliminating the need for additional power and reset parts. The simple structure further enhances the automation and reliability of debris collection.

[0021] In summary, this device not only enables automated feeding, cutting, precise positioning, and tight winding and knotting of warp and weft wires and knotting wires, effectively solving the defects of traditional wire mesh weaving equipment such as loose knots, uneven mesh, low forming accuracy, and non-adjustable spacing, but also significantly improves weaving quality and production efficiency. Furthermore, it integrates an adaptive spacing adjustment structure and a fully automatic debris cleaning and magnetic shielding structure. The equipment has a wide range of applications, occupies little space, has a low failure rate, and strong continuous operation capability, greatly enhancing the automation level and practical performance of wire mesh weaving equipment. It is suitable for industrial production of multi-specification, large-volume tight-wound wire mesh fences. Attached Figure Description

[0031] Example 1: As Figure 1 and Figure 7As shown, an embodiment of the present invention provides a weft-grid adjustable close-wound wire fence weaving mechanism, including a main frame 1, a warp wire feeding beam 2 and a snap-wire feeding beam 3 mounted on the main frame 1, a weft wire straightening plate 4 and a snap-wire straightening plate 5 mounted on the bottom of the main frame 1, weft and snap-wire guide rollers 6 mounted on the bottom of the main frame 1, a snap-wire feeding motor 7 mounted on one side of the main frame 1, and a warp wire feeding motor 7 mounted on the side of the main frame 1 closest to the snap-wire feeding motor 7. A warp wire feeding motor 8 is provided. A main warp wire feeding arm 9 is mounted on the main frame 1. A secondary warp wire feeding arm 10 is mounted on the side of the main frame 1 near the main warp wire feeding arm 9. A secondary warp wire feeding arm 11 is mounted on the main frame 1. A main warp wire feeding arm 63 is mounted on the side of the main frame 1 near the secondary warp wire feeding arm 11. Side-twisting assemblies are provided on both sides of the top of the main frame 1. The side-twisting assemblies are used to fix the two ends of the warp wire body 25. A buckling mechanism 20 is mounted on the top of the main frame 1. 0 is used to fix the warp yarn body 27 and the warp yarn body 25 at the intersection of the weft yarn body 26, thereby fixing the warp yarn body 25 and the weft yarn body 26. A warp yarn cutter 12 is installed on the side of the main frame 1 near the warp yarn feeding auxiliary swing arm 10. An edge yarn pressing plate 13 is installed on the side of the main frame 1 near the warp yarn cutter 12. A mounting base 14 is installed on the top of the main frame 1. A pressing plate 15 is installed on the mounting base 14. A feeding plate 16 is provided at the bottom of the pressing plate 15. The top of the main frame 1 is near the... A warp pusher 17 is installed on one side near the mounting base 14. A warp positioning sensing cylinder 22 is installed on the top of the main frame 1. The snap-fit ​​mechanism 20 includes a snap-fit ​​main body 21. A snap-fit ​​main body fixing plate 24 is installed at the bottom of the snap-fit ​​main body 21. A snap-fit ​​positioning sensing plate 23 is installed on the top of the snap-fit ​​main body 21. A snap-fit ​​wire feeding one-way head 38 adapted to the snap-fit ​​wire body 27 is installed at the bottom of the snap-fit ​​main body fixing plate 24. The snap-fit ​​wire feeding one-way head 38 is installed on the snap-fit ​​wire feeding crossbeam 3. The aforementioned warp wire body 25, weft wire body 26, and snap-fit ​​wire body 27 are the raw materials for weaving the wire fence. The aforementioned pressure plate 15 and wire feeding plate 16 have grooves adapted to the shape of the warp wire body 25 on the side near the warp wire body 25. The pressure plate 15 and wire feeding plate 16 work together to limit, guide, and clamp the warp wire body 25. The main frame 1 is externally connected to a warp yarn feeding and straightening mechanism and a net-pulling mechanism during use. The warp yarn feeding and straightening mechanism is used for feeding, conveying, and straightening the warp yarn body 25, while the net-pulling mechanism is used to pull the knotted net fence towards the top of the main frame 1. A warp yarn cutting nozzle is provided at the warp yarn cutting knife 12. The aforementioned warp yarn feeding and straightening mechanism, net-pulling mechanism, yarn feeding motor 7, and warp yarn feeding motor 8 are existing mature technologies, and their working principles and specific structures will not be described in detail here.In use, the device first feeds the warp yarn body 25 into the warp yarn cutting nozzle through the warp yarn feeding and straightening mechanism, and aligns the warp yarn pushing swing plate 17 with the warp yarn positioning sensing cylinder 22 to complete the station calibration. At the same time, the snap-on yarn feeding motor 7, through the snap-on yarn feeding main swing arm 63 and the snap-on yarn feeding auxiliary swing arm 11, drives the snap-on yarn feeding one-way head 38 on the snap-on yarn feeding beam 3 to accurately deliver the snap-on yarn body 27 to the working position of the snap-on yarn positioning sensing plate 23. Meanwhile, the warp yarn feeding motor 8, through the warp yarn feeding main swing arm 9 and the warp yarn feeding auxiliary swing arm 10, drives the warp yarn feeding beam 2 to move. The warp yarn feeding beam 2 drives the warp yarn cutting knife 12 to move and complete the fixed-length cutting of the warp yarn body 25. Simultaneously, through the coordinated movement of the pressure plate 15 and the feeding plate 16, the cut warp yarn body 25 is accurately fed into the working area inside the snap-on mechanism 20. After the warp yarn body 25 is fed into the knotting mechanism 20, the two ends of the warp yarn body 25 are first wrapped and fixed using the edge twisting assembly, effectively preventing the warp yarn body 25 from shifting or shaking during the knotting process, ensuring the stability and accuracy of the knotting operation. Then, the knotting mechanism 20 tightly wraps the knotting wire body 27 around the intersection of the warp yarn body 25 and the weft yarn body 26 to form a secure knot, achieving a stable connection between the warp yarn body 25 and the weft yarn body 26. After a single knotting operation is completed, the pressure plate 15 and the feed plate 16 work together to pull the knotted warp yarn body 25 and weft yarn body 26 out of the knotting mechanism 20, and then the pulling mechanism pulls them upwards, completing a single weaving cycle. This device, through the coordinated use of its various structures, can quickly complete the automated feeding, cutting, positioning, and knotting operations of the warp yarn body 25, weft yarn body 26, and knotting wire body 27. By pre-fixing both ends of the warp yarn body 25 before knotting, problems such as misaligned knots, loose knots, and mesh deformation are completely eliminated, significantly improving the weaving precision. Relying on the limiting and conveying structure of the pressure plate 15 and the feeding plate 16, the entire process of yarn picking, feeding, and unloading can be completed quickly, resulting in strong operational continuity and high production efficiency. Simultaneously, by adjusting the installation spacing of the knotting mechanism 20 on the main frame 1 and the installation spacing between adjacent warp yarn bodies 25, the knotting spacing and weft yarn arrangement spacing can be freely adjusted, adapting to the weaving needs of different warp and weft specifications and different mesh sizes. It is compatible with various weaving conditions and has a wide range of applications. The knotting mechanism 20 can be installed and fixed on the main frame 1 using detachable fixing structures such as screw fixing, thread fixing, or snap-fit ​​fixing. The installation and fixing method is not specifically limited and can be flexibly selected according to actual assembly and spacing adjustment requirements, making the spacing adjustment method of the knotting mechanism 20 flexible and diverse, with a wider adjustment range. It can achieve free and stepless adjustment of the weft spacing, and takes into account various weaving processes such as dense winding, regular winding and sparse winding. The formed mesh fence has uniform mesh, firm knots and high overall flatness. It effectively makes up for the defects of traditional equipment such as fixed spacing, poor adaptability and unstable finished product quality. The overall structure of the device is simple and compact, and it is convenient and quick to use.

[0032] like Figure 3 and Figure 4 As shown, the edge-twisting assembly includes an edge-twisting head 18 and an edge-twisting motor 19. The bottom of the edge-twisting head 18 is equipped with a gear transmission mechanism, and the output end of the edge-twisting motor 19 is connected to the gear transmission mechanism. The edge-twisting motor 19 drives the edge-twisting head 18 to rotate via a gear rotating component. The top of the edge-twisting head 18 is equipped with a limiting groove adapted to the shape of the warp yarn body 25. Both the gear transmission mechanism and the edge-twisting motor 19 are existing mature technologies, and their specific structures and working principles will not be elaborated upon here. During operation, the edge-twisting motor 19 drives the gear transmission mechanism to rotate, thereby rotating the edge-twisting head 18. This quickly winds and fixes the end of the warp yarn body 25 placed in the limiting groove of the edge-twisting head 18, effectively limiting the warp yarn body 25 from shifting or loosening during weaving and knotting processes, further ensuring the overall stability and weaving accuracy of the warp yarn body 25 during knotting operations.

[0033] like Figures 5 to 11As shown, the main fastening seat fixing plate 24 is installed on the main frame 1. A warp winding motor 28 is installed on one side of the main fastening seat body 21, and a weft winding motor 29 is installed at the bottom of the main fastening seat body 21. The output end of the warp winding motor 28 is fixedly connected to a warp winding drive bevel gear 31, and also includes a warp winding drive gear 32 and a warp winding gear 33. The warp winding drive bevel gear 31 meshes with the warp winding drive gear 32, and the warp winding drive gear 32 meshes with the warp winding gear 33. The output end of the weft winding motor 29 is fixedly connected to a weft winding lower drive gear 34, and also includes a weft winding... The system includes a lower gear 35, a weft yarn drive gear 36, and a weft yarn upper gear 37. The lower drive gear 34 meshes with the lower gear 35. A connecting post is provided between the lower drive gear 34 and the upper drive gear 36, and they are fixedly connected via the connecting post. The upper drive gear 36 meshes with the upper gear 37. A warp yarn winding nozzle 39 is fixedly connected to the side of the warp yarn winding gear 33 near the thread-fastening body 27. A cutting blade for cutting the thread-fastening body 27 is provided on the lower gear 35. The warp yarn winding motor 28, the weft yarn winding motor 29, and the thread-fastening one-way head 38 are all existing mature technologies; their specific structures and working principles will not be elaborated upon here. As described above, the installation method of the buckle main seat fixing plate 24 is the same as that of the buckle mechanism 20. When adjusting the installation spacing of the buckle mechanism 20, the buckle main seat fixing plate 24 can be adjusted synchronously to ensure the fitting accuracy of each structure. After each structure has delivered the weft yarn body 26 and the buckle yarn body 27 into place and completed the fixing operation of the warp yarn body 25, the warp yarn body 25 and the weft yarn body 26 form an interlaced state. First, the weft winding motor 29 runs, driving the lower weft winding drive gear 34, the lower weft winding gear 35, the upper weft winding drive gear 36, and the upper weft winding gear 37 to rotate synchronously. The cutting blade on the lower weft winding gear 35 cuts the buckle yarn body 27, which passes between the lower weft winding gear 35 and the upper weft winding gear 37, to a fixed length. After cutting, the lower weft winding gear 35 and the upper weft winding gear 37 continue to rotate, tightly winding and fixing the cut buckle yarn body 27 onto the weft yarn body 26. After the weft yarn body 27 completes the winding operation on the weft yarn body 26, the warp yarn motor 28 starts running. The warp yarn motor 28 drives the warp yarn transmission bevel gear 31 to rotate. The warp yarn transmission bevel gear 31 drives the meshing warp yarn drive gear 32 and warp yarn gear 33 to drive the winding warp yarn nozzle 39 through multi-stage gear cooperation, thereby winding and fixing the weft yarn body 27 onto the warp yarn body 25.After the bidirectional winding and knotting operation of the warp yarn body 25 and the weft yarn body 26 is completed, the warp yarn feeding motor 8 continues to run and drives the warp yarn feeding beam 2 to move. With the help of the limiting conveying structure of the pressure plate 15 and the feeding plate 16, the warp yarn body 25 and the weft yarn body 26 that have completed the knotting are smoothly released from the inside of the knotting mechanism 20. Then, the pulling mechanism pulls the material upward to complete a single complete weaving work cycle. The knotting mechanism 20 is arranged as follows. Figure 10 As shown. The components of this mechanism are compactly arranged and rationally laid out, significantly reducing the overall space occupied by the buckling mechanism. Through precise multi-stage gear transmission, the bidirectional winding and knotting of the weft and warp threads are completed separately, achieving an integrated forming and knotting process. The high precision of the coordinated operation of each structure can meet the weaving requirements of densely wound wire mesh fences with smaller weft spacing, greatly expanding the processing range of the equipment. Furthermore, the overall structure is compact, smaller in size, and more integrated. The gear transmission is stable with small transmission errors, and the number of winding turns is uniform, effectively improving the regularity of the knot formation and the firmness of the connection, eliminating loosening and detachment, and significantly improving the overall structural strength and finished product quality of the densely wound wire mesh fence.

[0034] Furthermore, both the lower gear 35 and the upper gear 37 of the weft winding are provided with through slots adapted to the thread-threading body 27, which can guide the thread-threading body 27 and prevent the thread-threading body 27 from shifting during winding. The lower gear 35 and the upper gear 37 of the weft winding are both provided with limiting slots adapted to the shape of the warp yarn body 25 on the side near the warp yarn body 25, to avoid obstructing the weft yarn and thread-threading guide roller 6, and to fit and support the weft yarn body 26 during winding, restricting its movement and preventing it from shifting during winding, thus ensuring the regularity of the knot formation. The gear 33 of the warp winding is located near... A clearance slot adapted to the shape of the warp yarn body 25 is provided on one side of the warp yarn body 25 to avoid the warp yarn body 25 when positioning it. The main body 21 of the buckle is equipped with a top warp and weft yarn center post 30 on the side near the warp yarn body 25. A cross-shaped groove is provided on the side of the top warp and weft yarn center post 30 near the warp yarn body 25. The warp yarn body 25 and the weft yarn body 26 are confined in the cross-shaped groove. The weft yarn body 26 is placed on the inside and the warp yarn body 25 is pressed on the outside. This can simultaneously constrain the interlaced warp and weft yarns, stably limit their relative positions throughout the winding and knotting process, prevent the yarn from shifting or misaligning, and ensure that the net is formed evenly and firmly.

[0035] Example 2: Figure 5 and Figures 9 to 18 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: This invention provides a weft spacing-adjustable close-wound wire mesh fence weaving mechanism, comprising a first mounting frame 40 mounted on one side of the snap-fit ​​main body 21, a magnetic post 41 mounted on the first mounting frame 40, a connecting frame 45 sleeved on the magnetic post 41, a lower scraper 46 fixedly connected to the bottom of the connecting frame 45, an upper scraper 47 fixedly connected to the top of the connecting frame 45, and non-magnetic sections 42 provided at both the top and bottom of the magnetic post 41; a second mounting frame 43 fixedly connected to one side of the first mounting frame 40, a threaded post 44 rotatably connected to the second mounting frame 43, a transmission component 51 provided at the bottom of the threaded post 44, the transmission component 51 meshing with the weft winding lower gear 35; the side of the connecting frame 45 away from the first mounting frame 40 sleeved on the threaded post 44, and a threaded sleeve provided on the side of the connecting frame 45 near the threaded post 44; a collection box 48 mounted at the bottom of the first mounting frame 40, and a conveying cylinder 49 mounted at the top of the collection box 48. A baffle body 50 is fixedly connected to the bottom of the conveying cylinder 49, and a base plate 55 is fixedly connected to the bottom of the baffle body 50. A second slot 56 is provided on the base plate 55. A first slot 54 is provided on both the top and bottom of the conveying cylinder 49. A third connecting piece 57 is fixedly connected to the top of the conveying cylinder 49. A hook portion 58 is provided on the top of the third connecting piece 57. A first connecting piece 52 is rotatably connected to the side of the upper scraper 47 near the conveying cylinder 49. A second connecting piece 53 is fixedly connected to both sides of the first connecting piece 52. The side of the second connecting piece 53 away from the first connecting piece 52 is fixedly connected to the upper scraper 47. Two sets of first mounting brackets 40 and second mounting brackets 43 are provided. The two sets of first mounting brackets 40 and second mounting brackets 43 are respectively installed on the upper and lower parts of one side of the buckle main body 21. A magnetic column 41 is fixedly assembled between the two sets of first mounting brackets 40, and a threaded column 44 is rotatably mounted between the two sets of second mounting brackets 43. The transmission component 51 is a mature existing technology, and its specific structure and working principle will not be described in detail here. The bottom plate 55 has an overall inclined structure, and the bottom of the upper scraper 47 is also inclined; optionally, the conveying cylinder 49 is made of DT4 electrical pure iron magnetic shielding material, and the first connecting piece 52 has elastic deformation capability to isolate the magnetic attraction force. When the knotting operation is performed inside the knotting mechanism 20, the positioning cutting and wire twisting processes will generate metal debris; the magnetic columns 41 arranged on both sides of the knotting main body 21 can attract the magnetic metal debris, temporarily gathering and adsorbing the debris on the outer wall of the magnetic column 41. During operation, the transmission component 51 is driven to rotate synchronously by the rotation of the lower gear 35 of the weft yarn inside the buckling mechanism 20. The transmission component 51 drives the threaded column 44 to rotate, and drives the connecting frame 45 to move axially along the threaded column 44 through the threaded sleeve transmission pair, so that all the matching components on the connecting frame 45 move synchronously. During the movement, the connecting frame 45, the lower scraper 46 and the upper scraper 47 slide close to the outer wall of the magnetic column 41, scraping off the metal debris adsorbed on the surface of the magnetic column 41 and temporarily storing it inside the lower scraper 46 and the upper scraper 47.When the lower scraper 46 moves to the non-magnetic section 42 at the bottom of the magnetic column 41, the debris detaches from the magnetic attraction range of the magnetic column 41, loses its magnetic attraction, and falls into the baffle body 50 under its own weight. Guided by the inclined bottom plate 55, the metal debris flows along the slope to the second slot 56, and after passing through the second slot 56, it is collected and stored in the collection box 48. When the upper scraper 47 moves to the non-magnetic section 42 at the top of the magnetic column 41, the debris also detaches from the magnetic attraction and accumulates inside the upper scraper 47 by its own weight. During the movement of the upper scraper 47 toward the top of the threaded column 44, the third connecting piece 57 above the threaded column 44 hooks the first connecting piece 52 on the side of the upper scraper 47, and the ends of the two are engaged and limited. Because the third connecting piece 57 remains fixed, the moving upper scraper 47 pulls the first connecting piece 52 to elastically deform and unfold outward, simultaneously causing the second connecting pieces 53 on both sides to open. After unfolding, the discharge port on the side of the upper scraper 47 closest to the conveying cylinder 49 is completely open. The first connecting piece 52 and the third connecting piece 57 cooperate to form an inclined guide plate, and the second connecting pieces 53 on both sides act as a barrier to prevent debris from splashing and scattering. The debris falls from the inside of the upper scraper 47 into the conveying cylinder 49 by its own weight, and after being guided by the conveying cylinder 49 and the baffle body 50, it is finally collected in the collection box 48. The above components work together to achieve an integrated operation of automatic adsorption, scraping, diversion, and centralized collection of metal debris at the knotting station. No manual shutdown is required to clean the debris, ensuring the cleanliness of the knotting station and preventing metal debris from getting stuck in gears or wires, which could lead to misalignment or equipment jamming. Furthermore, the magnetic shielding material of the conveyor cylinder 49 prevents secondary magnetic adsorption of debris, and the elastic first connecting piece 52 can automatically open and close to unload the material. The overall structure is integrated into the side of the knotting mechanism, without occupying the core weaving work space, balancing the debris recycling function with the compactness of the whole machine, and significantly extending the continuous trouble-free operation time of the equipment.

[0036] Furthermore, both the lower scraper 46 and the upper scraper 47 are conical, and the inner wall of the cone can gather and guide the scraped metal debris. The second connecting piece 53 is an integrated elastic louvered baffle structure, which is integrally formed with the first connecting piece 52. Under normal conditions, it folds up and adheres to the side wall of the upper scraper 47 along with the first connecting piece 52. When unloading, it unfolds and folds outward in a symmetrical louvered manner, forming a barrier and shielding area on both sides simultaneously. The first connecting piece 52 and the second connecting piece 53 are made of high-toughness, wear-resistant polyurethane elastic material. They rely on their own material deformation stress to achieve natural rebound without external force. When the third connecting piece 57 disengages from the first connecting piece 52 and is locked in place, the first connecting piece 52 and the second connecting piece 53 can automatically retract and reset without the need for additional spring components. The polyurethane substrate is wear-resistant and resistant to metal shavings friction, resistant to repeated bending fatigue, and not prone to cracking or breakage during long-term high-frequency opening and closing. It has a long service life and is not prone to wear and failure. A connecting block 61 is fixedly connected to the side of the first connecting piece 52 near the third connecting piece 57, which makes the connection surface between the first connecting piece 52 and the third connecting piece 57 smoother and allows for a smooth transition between the contact positions of the first connecting piece 52 and the third connecting piece 57, making the first connecting piece 52 more stable and the second connecting piece 53 more stable. The connection surfaces of the first connecting piece 52 and the third connecting piece 57 are smoother, allowing the metal inside the upper scraper 47 to smoothly enter the conveying cylinder 49. The first connecting piece 52 has a protrusion 59 on the side near the third connecting piece 57 that matches the shape of the hook portion 58, and a recess 60 on the side near the third connecting piece 57 that matches the shape of the hook portion 58. This allows the first connecting piece 52 and the third connecting piece 57 to be stably connected together, making it less likely to detach during unloading. The connecting frame 45 has a clearance groove 62 that matches the shape of the first connecting piece 52, providing clearance space when the first connecting piece 52 and the second connecting piece 53 are elastically unfolded outward, preventing the connecting frame 45 from squeezing and interfering with the opening and closing actions of the first connecting piece 52 and the second connecting piece 53.

[0037] Optionally, the aforementioned magnetic automatic chip removal structure can be omitted, and a pneumatic cleaning mechanism can be installed inside the clipping mechanism 20. This pneumatic cleaning mechanism includes a solenoid valve, connecting pipes, an air storage pipe, an air distribution outlet connector, and an aluminum base air inlet connector. The solenoid valve has an oil inlet and an air inlet, allowing lubricating oil and compressed air to enter the air storage pipe through their respective ports. The air distribution outlet connector and the aluminum base air inlet connector are connected by a sealed air pipe to stably transmit the oil-gas medium. The equipment can be preset with a cleaning cycle. After the set working time is reached, the solenoid valve automatically opens and closes, instantly spraying out the high-pressure oil-gas mixture stored in the air storage pipe at high speed. On the one hand, the high-speed airflow quickly blows away the iron filings accumulated inside the clipping mechanism 20; on the other hand, it simultaneously delivers lubricating oil to the gear transmission pair for lubrication and maintenance. This alternative solution has fewer parts, a simpler overall structure, and allows for simultaneous chip removal and transmission component lubrication, resulting in high work efficiency and convenient operation.

[0038] The working principle of the technical solution provided by this invention is as follows:Before use, first complete the assembly of the main frame 1. Adjust the buckling mechanism 20 and the buckling main seat fixing plate 24 to the target mesh weft wire spacing. The buckling mechanism 20 can be fixed to the main frame 1 in any detachable way, such as by screws, threads, or snap-fit. When adjusting the spacing of the buckling mechanism 20, the buckling main seat fixing plate 24 should be adjusted synchronously to ensure transmission accuracy. Insert the warp wire body 25, weft wire body 26, and buckle wire body 27 into the corresponding workstations. Connect the warp wire body 25 to the external warp wire feeder for straightening. The mechanism includes an external mesh pulling mechanism at the top of the machine; the edge twisting assembly edge twisting head 18 and edge twisting motor 19 are pre-calibrated, and the top limiting groove of the edge twisting head 18 is aligned with the conveying path of the warp yarn body 25; the knotting assembly buckling mechanism 20 internal gear transmission components drive the warp yarn through the bevel gear 31 to the upper gear 37 of the weft yarn, and the cutting knife completes the alignment of the lower gear 35 of the weft yarn; the debris collection assembly first mounting frame 40 and the clearance groove 62 are assembled in place, and the conical collection chambers of the lower scraper 46 and the upper scraper 47 are aligned with the magnetic column 41. In use: The warp yarn body 25 is fed to the warp yarn cutting nozzle of the warp yarn cutting knife 12 by the warp yarn feeding and straightening mechanism. The warp yarn pushing swing plate 17 moves to the warp yarn positioning sensing cylinder 22 to complete the station calibration. The thread-fastening feeding motor 7, in conjunction with the thread-fastening feeding main swing arm 63 and the thread-fastening feeding auxiliary swing arm 11, drives the thread-fastening feeding one-way head 38 on the thread-fastening feeding beam 3 to feed the thread-fastening body 27 to the thread-fastening positioning sensing plate 23 station. Simultaneously, the warp yarn feeding motor 8, in conjunction with the warp yarn feeding main swing arm 9 and the warp yarn feeding auxiliary swing arm 11, drives the thread-fastening feeding crossbeam 3 to the thread-fastening feeding one-way head 38 to feed the thread-fastening body 27 to the thread-fastening positioning sensing plate 23 station. The warp wire feeding arm 10 drives the warp wire feeding beam 2, which in turn drives the warp wire cutting blade 12 to cut the warp wire body 25. The pressure plate 15 and the feeding plate 16 cooperate with the groove to clamp and limit the warp wire body 25, and send the cut warp wire body 25 into the knotting mechanism 20. The side twisting assemblies on both sides of the top of the main frame 1 are activated. The side twisting motor 19 drives the side twisting head 18 to rotate through gear transmission. The side twisting head 18 is fixed by the limiting groove of the side twisting head 18 to wrap around and fix the two ends of the warp wire body 25 to prevent the warp wire body 25 from shifting and shaking when knotting. After the main body 25 and the weft yarn main body 26 are crossed and positioned, the weft yarn winding motor 29 drives the lower weft yarn drive gear 34, the lower weft yarn gear 35, the upper weft yarn drive gear 36, and the upper weft yarn gear 37 to rotate. The cutting blade on the lower weft yarn gear 35 cuts the weft yarn main body 27, and the rotation of the lower weft yarn gear 35 and the upper weft yarn gear 37 winds the weft yarn main body 27 around the outside of the weft yarn main body 26. Subsequently, the warp yarn winding motor 28 drives the warp yarn drive bevel gear 31 and the warp yarn drive gear 32. The gear set of the warp yarn gear 33 is linked, which drives the winding warp yarn nozzle 39 to wrap the snapping yarn body 27 around the outside of the warp yarn body 25, thus completing the fastening of the warp yarn body 25 and the weft yarn body 26. The warp yarn feeding motor 8 continuously drives the warp yarn feeding beam 2, and the pressing sheet 15 and the feeding sheet 16 cooperate to remove the formed net body from the snapping mechanism 20. The external net pulling mechanism pulls the net fence upward. A single weaving cycle is completed, and the equipment automatically repeats the process of feeding, cutting, and knotting yarn for continuous production.Metal scraps are generated during the knotting and cutting process. Magnetic column 41 attracts these scraps. The rotation of the weft gear 35 drives the transmission component 51 and the threaded column 44 to rotate. The threaded transmission drives the connecting frame 45 to move along the threaded column 44. The lower scraper 46 and upper scraper 47 scrape off the scraps and temporarily store them against the outer wall of the magnetic column 41. The lower scraper 46 moves to the non-magnetic section 42 at the bottom of the magnetic column 41: the scraps are released from the magnetic attraction, flow along the inclined bottom plate 55, and fall into the collection box 48 through the second slot 56. The upper scraper 47 moves to the top of the magnetic column 41. Non-magnetic section 42: Debris accumulates inside the conical upper scraper 47. The third connecting piece 57 hooks the first connecting piece 52, and the integrated louvered structure of the second connecting piece 53 folds outward and expands. It unfolds by relying on the elastic deformation of polyurethane itself. The first connecting piece 52 and the third connecting piece 57 form a guide plate, and the second connecting piece 53 blocks the debris from splashing. The debris falls into the magnetic shielding material conveying cylinder 49 and finally flows into the collection box 48 for collection. After the hooking is broken, the first connecting piece 52 and the second connecting piece 53 automatically rebound and retract by the toughness of the material. After use, stop the wire feeding and stop the machine after the current net body discharge cycle is completed; remove the collection box 48, empty the accumulated metal shavings inside, and reset it after cleaning; if it is necessary to replace the wire mesh fence with a different specification, loosen the fixing structure between the buckle mechanism 20 and the main frame 1, readjust the installation spacing of the buckle mechanism 20, and adjust the position of the buckle main seat fixing plate 24 at the same time. After the adaptation and debugging are completed, the machine can be turned on again; check the elastic louver baffles of the first connecting piece 52 and the second connecting piece 53. The polyurethane material is resistant to bending and not easily damaged. If there is no crack or deformation, it can be directly retained. If wear occurs after long-term use, it can be replaced individually. This device has a compact structure and is easy to use.
