Description

Technical Field

[0001] This application relates to the field of wire mesh weaving, and in particular to a weaving mesh, a wire twisting device, a wire mesh weaving machine, and a weaving method. Background Technology

[0002] Woven wire mesh is commonly used in various fields such as transportation, protection, storage, and screening. The materials and styles used vary depending on the application requirements. Woven wire mesh generally consists of two or more threads intertwined at certain intervals to form a mesh structure. For example, common types of metal mesh include diamond mesh and hexagonal mesh.

[0003] This type of woven mesh is typically produced automatically using wire mesh weaving machines. These machines are mainly of two types. One type involves periodically bending the steel wire and then longitudinally transmitting it to the mesh-making area. The bent wire is then hooked to one end of the mesh and transmitted longitudinally, continuously hooking to form a complete mesh. The second type uses a specific twisting structure to intertwine and extend multiple wires to weave the mesh.

[0004] However, all of the above are composed of intertwined threads. Since threads are easily bent and twisted, it means that the threads have good ductility but low stiffness. Nets made in this way have low overall strength and will deform significantly when subjected to impact, such as bulging to one side, resulting in poor protective effect.

[0005] In response, the applicant designed a new woven mesh structure and specialized equipment for the automated production of this woven mesh structure. Summary of the Invention

[0006] In order to improve the protective effect of woven mesh and realize the automated production of new woven mesh, this application provides a woven mesh, a wire twisting device, a wire mesh weaving machine and a weaving method.

[0007] In the first aspect, this application provides a woven mesh, which adopts the following technical solution:

[0008] A woven mesh includes several threads and several cores, wherein the cores are wires with a stiffness greater than that of the threads. The length direction of the cores is transverse, and the cores are arranged longitudinally. The threads meander through at least two cores and extend transversely. Each thread is wound around a core at least once. Except for the cores located at the edge, the winding nodes of different threads on the same core are basically overlapping.

[0009] By adopting the above technical solution, a mesh is formed by using a wire core as the skeleton and the wires winding back and forth between the skeleton. When any point of the mesh is impacted, the two wire cores closest to the impact point will directly experience the force. The other wire cores and wires assist in applying force to these two wire cores. Because the wire core has relatively high rigidity and bending strength compared to the wires, and the mesh is divided into small modules by the core, the impact point is close to the boundary that directly resists the force, resulting in a small space for elastic or plastic deformation and minimal deformation of the mesh when stretched. In this application, this force boundary is the wire core, while in the prior art it is the outer frame. Therefore, this distance difference is very large, and the reliability of the protection also differs greatly.

[0010] Furthermore, since the winding nodes are the same, that is, the torque generated by different threads on the same core is very small, and the core is not easy to bend or break; thus, the entire woven mesh can maintain high rigidity and impact resistance, giving the woven mesh of this application a strong protective effect.

[0011] Optionally, the thread meanders through three cores, with the threads between any two cores forming a V-shape, and the V-shapes formed by different threads are arranged alternately in the transverse direction.

[0012] By adopting the above technical solution, on the one hand, a small triangle is formed between the thread and two adjacent cores, with one core serving as the side of the triangle and the other core serving as the fixed point of the apex; a large triangle is formed between the thread and the two furthest of the three adjacent cores, in the same manner; thus, the overall woven mesh has greater structural stability; on the other hand, the area between two adjacent cores has two threads forming the mesh, making it less likely that the overall reliability will decrease due to the loosening of one thread.

[0013] In a second aspect, this application provides a wire-tightening device, which adopts the following technical solution:

[0014] A wire twisting device includes a frame, a wire twisting mechanism, an external drive mechanism, and an internal drive mechanism. The wire twisting mechanism includes an upper slide plate, a lower slide plate, and an internal drive component. The external drive mechanism can drive one of the upper and lower slide plates to translate relative to the other along the length direction of the lower slide plate. Both the upper and lower slide plates are embedded with a plurality of crescent-shaped wheels arranged along the sliding direction. Two crescent-shaped wheels distributed vertically are stacked to form a wire twisting wheel. Each crescent-shaped wheel has at least one threading hole for a lower stiffness wire to pass through. Two crescent-shaped wheels distributed vertically together form a core hole for a higher stiffness wire to pass through. When the upper and lower slide plates translate relative to each other, they drive the crescent-shaped wheels to translate. A floating mechanism is matched to one side of the lower slide plate. When one of the upper and lower slide plates translates relative to the frame, the floating mechanism forces the higher stiffness wire into the half-hole of the corresponding core hole. The internal drive component is embedded in one of the upper and lower slide plates, and the internal drive mechanism drives the wire twisting wheel to rotate through the internal drive component.

[0015] By adopting the above technical solution, the lower stiffness wire is called the wire thread, and the higher stiffness wire is called the wire core. In subsequent descriptions, "wire thread" and "wire core" will be used interchangeably. The twisting wheel is composed of a split-type crescent wheel. This twisting wheel can be rotated as a whole or rearranged by misaligning the crescent wheels. During rotation, the internal drive mechanism drives the twisting wheel to rotate through an internal drive component embedded in the twisting mechanism. At this time, the wire thread on the crescent wheel will wind around the wire core. During misalignment adjustment, one of the upper and lower sliding plates can be moved to align a specific wire core with the correct alignment. The half-moon wheel is adjusted to the position corresponding to the adjacent wire core, which transfers the position of the wire corresponding to the half-moon wheel to the adjacent wire core; then the twisting wheel is rotated again to wind the wire onto the adjacent wire core; in this way, when multiple twisting wheels alternate back and forth, a web can be woven from a certain number of wire cores by connecting the wire cores; the existence of the floating mechanism allows the wire cores to avoid the movement path of the half-moon wheel during the horizontal movement and misalignment adjustment process, so that the wire cores always stay in the original position and do not interfere with the horizontal movement.

[0016] In summary, the wire twisting device provides the basis for weaving, enabling the wires to be woven onto the core without adjusting its position. In other words, the core will not undergo any undesirable twisting during the weaving process, allowing the core to be made of a material with a certain degree of rigidity, so as to automatically weave this new type of woven mesh with excellent protective effect.

[0017] Optionally, the crescent wheels of the upper and lower slide plates can be divided into two types. The first type of crescent wheel is equipped with a wire feed drum for winding the thread at one end. The wire feed drum can rotate on its own and can rotate with the crescent wheel. The second type of crescent wheel is not equipped with a wire feed drum. There are at least two second type crescent wheels, which are distributed at the beginning and end of the first type of crescent wheel in the direction of arrangement.

[0018] By adopting the above technical solution, the second type of semi-circular wheel does not match the wire feed drum, and no wire passes through it. In this way, for the wire core located at the edge, different wires will not repeatedly wrap around and repeat the same point; eventually, different wires will form an alternating distribution along the length of the wire core at the winding node of the wire core.

[0019] Optionally, the frame is provided with two wire twisting mechanisms, and the wire feed cylinder is located between the opposite semi-circular wheels of the two wire twisting mechanisms. The semi-circular wheels are fixed with mandrels, and the two ends of the wire feed cylinder are respectively sleeved on the mandrels of different semi-circular wheels and rotatably connected to the mandrels.

[0020] By adopting the above technical solution, both ends of the feed cylinder are connected to the semi-circular wheel, which can ensure that the feed cylinder is not prone to shaking or different rotation amplitudes during its rotation and rotation with the semi-circular wheel, thus ensuring the stability of the wire feeding.

[0021] Optionally, the feed tube includes an outer tube and an inner tube. One end of the outer tube is sleeved on the mandrel of one of the semi-lunar wheels. The other end of the outer tube is hollow and has an opening. The inner tube is embedded in the open end of the outer tube. The outer tube has an elastic element embedded in it that forces the inner tube to have an outward tendency. The inner tube is sleeved on the mandrel of the other semi-lunar wheel.

[0022] By adopting the above technical solution, the inner cylinder can elastically extend and retract with the outer cylinder, realizing easy disassembly and assembly between the wire feed cylinder and the wire twisting mechanism; after installation, since the wire feed cylinder is only subjected to rotational and pulling forces in the direction of wire exit, it is only necessary to turn the closed end of the outer cylinder towards the direction of wire exit to prevent the wire feed cylinder from becoming loose; if the elastic force of the elastic element is large enough, the end with the inner cylinder can also be turned towards the direction of wire exit to provide a certain degree of buffering.

[0023] Optionally, the outer cylinder without an opening has a spherical guide head and a connector in sequence. The maximum outer diameter of the spherical guide head is greater than the outer diameter of the outer cylinder body, and the maximum outer diameter of the connector is less than the outer diameter of the outer cylinder body. The connector is sleeved on the mandrel of the crescent wheel through which the silk thread passes.

[0024] By adopting the above technical solution, the transmission of the silk thread through the spherical guide head is smoother, and the relationship of the outer diameter ensures that the silk thread will always pass through the outer wall of the spherical guide head, making it less likely to cause knotting.

[0025] Optionally, the external drive mechanism includes at least two drive units, which drive one of the upper slide plate and the lower slide plate respectively. Each drive unit includes a drive source, a rotating shaft driven by the drive source, a swing arm that swings with the rotation of the rotating shaft, and a connecting arm that forms a swing pair with the swing arm. The connecting arm is hinged to the corresponding upper slide plate or lower slide plate, and the drive source and the rotating shaft are both mounted on the frame.

[0026] By adopting the above technical solution, on the one hand, the rotational drive speed has very strong controllability. Through the transmission of the swing arm and the adapter arm, the rotational drive is transformed into the horizontal movement of the upper and / or lower slide plates, making the horizontal movement speed of the upper and lower slide plates more controllable. On the other hand, the rotation of the swing arm has strong periodicity, which can ensure that the upper and lower slide plates are minimally affected by the stroke difference, making the stopping position sufficiently accurate.

[0027] Optionally, the frame is provided with two screw-tightening mechanisms, one of which drives two upper slide plates synchronously, and the other drive unit drives two lower slide plates synchronously. The rotating shaft is fixed with a driven gear, and a swing arm is connected to each end of the rotating shaft. One of the swing arms is fixed to the driven gear or is part of the driven gear. The drive source drives the driven gear to rotate through gear transmission.

[0028] By adopting the above technical solution, the gear transmission can establish a suitable reduction ratio, and the rotating shaft can synchronously transmit power to the two upper or lower slide plates, ensuring the consistency of the two screw-twisting mechanisms.

[0029] Optionally, the thread-tightening wheel includes a head, a tail, and a shaft. The head and tail are fixed to the two ends of the shaft, respectively. The shaft passes between the upper slide plate and the lower slide plate. The shaft is provided with a thread-tightening gear. The internal drive component is a rack that cooperates with the thread-tightening gear. The internal drive mechanism can drive the rack to slide along the length direction of the lower slide plate. The internal drive mechanism is fixed to one of the upper slide plate and the lower slide plate.

[0030] By adopting the above technical solution, on the one hand, the consistency of power transmission between multiple screwing wheels is ensured, and on the other hand, it is ensured that when the half-moon wheel moves with the upper or lower slide plate, one of the half-moon wheels and the rack always remain in a meshed state, thereby ensuring that the half-moon wheel can be smoothly driven to rotate when it is reassembled into a screwing wheel.

[0031] Optionally, the floating mechanism includes a bracket mounted on the frame, a support frame that can be raised and lowered along the bracket, a driven member fixed to the support frame, and an active member fixed to the lower slide plate. The active member abuts against the bottom surface of the driven member and supports the driven member. The bottom surface of the driven member has concave and convex features that form a track. The position where the lower slide plate stops translating corresponds to the concave surface of the driven member. When the lower slide plate moves, the driven member is lifted accordingly.

[0032] By adopting the above technical solution, the wire core and the woven wire mesh have a tendency to sink due to gravity. Therefore, the wire core will float up and down with the lifting and lowering of the support frame. Through the active and passive components, the horizontal movement of the lower slide can be associated with the vertical floating of the support frame, so that the support frame can float and sink in response to the movement of the upper and lower slides.

[0033] Thirdly, this application provides a wire mesh weaving machine, which adopts the following technical solution:

[0034] A wire mesh weaving machine includes the aforementioned wire twisting device, and also includes a discharge device for discharging the woven mesh and providing traction power, wherein the feeding device is located upstream of the wire twisting device and the discharge device is located downstream of the wire twisting device.

[0035] By adopting the above technical solution, the traction of the discharge device can keep the wire core moving, and the wire is gradually output as the wire is wound around by the twisting device.

[0036] Optionally, the discharge device includes a base, a drive shaft rotatably connected to the base, a drive component that drives the drive shaft to rotate, and a plurality of transmission gears arranged axially along the drive shaft. The transmission gears have teeth that can pass through the mesh of the woven mesh. The transmission gears include a central gear and side gears distributed on both sides of the central gear. The teeth are distributed circumferentially on the side gears. The teeth on both sides of the central gear that are opposite to each other form a groove between the central gear and the outer circumferential surface of the central gear.

[0037] By adopting the above technical solution, during operation, the harder wire core in the woven mesh will pass through the groove, and the gear teeth on both sides of the groove will be embedded into the adjacent mesh holes on both sides of the wire core. In this way, the stability of the conveying can be greatly improved, and the deformation of the mesh during the conveying process can be reduced or even avoided.

[0038] Fourthly, this application provides a wire mesh weaving method, which adopts the following technical solution:

[0039] A wire mesh weaving method includes the following steps: a) selecting easily bendable wires and wire cores with relatively high hardness; b) arranging multiple wire cores in parallel and continuously feeding them along their length; each wire moves back and forth along the arrangement direction of the wire cores, passing through at least two wire cores during the movement, and wrapping around at least one turn around each wire core; adjacent wires are interchanged during the back-and-forth movement and rotation between wire cores, so that at least two different wires are distributed in the area between adjacent wire cores; and during this process, the wire cores do not produce any undesirable bending.

[0040] By adopting the above technical solution, the silk threads are woven into a net based on the silk core, and the silk core does not bend during the process, thus maintaining the overall woven net's good impact resistance.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. The mesh is constructed with a core of silk threads as its framework, with the threads winding back and forth between the framework. When any point in the mesh is impacted, the two core threads closest to the impact point directly experience the force. The other core threads and other threads further contribute to the force applied to these two core threads. Because the core threads have relatively high rigidity and bending strength compared to the threads, and because the mesh is divided into small modules by the core, the impact point is close to the boundary that directly resists the force, resulting in a small space for elastic or plastic deformation. Therefore, the amount of deformation of the mesh when stretched is minimal. Furthermore, because the winding nodes are identical, the torque generated by different threads on the same core thread is small, and the core thread is less prone to bending or breaking. Thus, the entire woven mesh maintains high rigidity and impact resistance.

[0043] 2. The twisting wheel is composed of separate crescent-shaped wheels. These wheels can be rotated as a single unit or rearranged by misalignment. During rotation, the internal drive mechanism, through the internal drive component embedded in the twisting mechanism, drives the twisting wheel to rotate, allowing the crescent-shaped wheels to wind the thread onto the core. During misalignment adjustment, one of the upper or lower sliding plates can be moved to adjust the crescent-shaped wheel corresponding to a specific core to the position corresponding to an adjacent core, thus transferring the position of the thread corresponding to the crescent-shaped wheel to the adjacent core. The twisting wheel is then rotated again to wind the thread onto the adjacent core. Thus, when multiple twisting wheels alternate back and forth, a web can be woven from a certain number of cores, with the threads connecting the cores. The floating mechanism ensures that the cores avoid the movement path of the crescent-shaped wheels during horizontal movement and misalignment adjustment, keeping the cores in their original position without interfering with the horizontal movement. This allows for the automated production of this new type of woven web.

[0072] The present application will be further described in detail below with reference to the accompanying drawings.

[0073] This application discloses a woven mesh, a wire twisting device, a wire mesh weaving machine, and a weaving method.

[0074] Example 1:

[0075] Reference Figure 1 A woven mesh includes a plurality of wires 300 and a plurality of wire cores 400, the specific number of which depends on the size and strength requirements of the mesh to be manufactured. The wire cores 400 are wires with a stiffness greater than that of the wires 300. This stiffness can be reflected by dimensional specifications or material properties, such as polymer wires and fine iron wires. In this embodiment, the wires 300 are exemplified by fine iron wires, and the wire cores 400 are exemplified by reinforcing steel bars.

[0076] Regarding the direction, in this embodiment, the length direction of the core 400 is considered transverse. The cores 400 are arranged longitudinally, and the threads 300 meander through at least two cores 400 and extend transversely, with each thread 300 winding around a core 400 at least once. For ease of understanding, two different threads are selected in the figure and represented by different line types, namely thread one and thread two. It can be seen that the threads 300 between any two cores 400 form a V-shape, and the V-shapes formed by different threads 300 are alternately arranged transversely. This embodiment takes an example where each thread 300 meanders through three cores 400; every three cores 400 form a group, and each group is wound with two threads 300. Each thread 300 is periodically distributed transversely in an inclined N-shape, and the pattern formed by these two threads 300 is symmetrically distributed with the core 400 in the middle as the center of symmetry.

[0077] For the woven mesh as a whole, the position where the silk thread 300 winds around the silk core 400 is taken as the winding node. For the two outermost silk cores 400, different silk threads 300 are alternately distributed at the winding nodes of the same silk core 400. For the other silk cores 400 except those at the edge, the winding nodes of different silk threads 300 basically overlap on the same silk core 400. It should be noted that: the winding node here refers to a region on the silk core 400, the area covered by a certain number of turns of the silk thread 300 on the silk core 400 in a single winding, for example, two turns in this embodiment; while basically overlap means that two different silk threads 300 are closely wrapped or intertwined within the region of the winding node, appearing as overlapping or densely packed points from the perspective of the entire mesh surface.

[0078] In addition, if necessary, crossbars 500 spanning all the wire cores 400 can be welded onto the woven mesh after it has been formed.

[0079] Example 2:

[0080] Reference Figure 2 A wire twisting device is provided for the automated manufacturing of the aforementioned woven mesh. It includes a frame 1, a wire twisting mechanism 2, and a floating mechanism 3. Two wire twisting mechanisms 2 are symmetrically mounted on the frame 1. In this embodiment, the plane of symmetry is a vertical plane passing through the geometric center of the frame 1. An external drive mechanism 5 and a wire feed drum 4 are provided in the area between the two wire twisting mechanisms 2. The wire feed drum 4 is wound with raw wire 300. The floating mechanism 3 includes a first floating unit 301 and a second floating unit 302. The first floating unit 301 is located upstream of the two wire twisting mechanisms 2, dynamically guiding the wire core 400 into the wire twisting mechanism 2. The second floating unit 302 is located downstream of the two wire twisting mechanisms 2, dynamically guiding the woven mesh out; this avoids interference between the wire core 400 and the movement of the wire twisting mechanism 2 during wire feeding and output.

[0081] The wire-twisting mechanism 2 includes an upper slide plate 21 and a lower slide plate 22. An external drive mechanism 5 can drive one of the upper slide plate 21 and the lower slide plate 22 to translate relative to the other along the length of the lower slide plate 22. In this embodiment, the lower slide plate 22 is slidably connected to the frame 1, and the upper slide plate 21 is slidably connected to the lower slide plate 22. Both the upper slide plate 21 and the lower slide plate 22 can be moved by the external drive mechanism 5. In other embodiments, only one of the upper slide plate 21 and the lower slide plate 22 may be able to slide relative to the frame 1; if both can slide, the sliding carrier of the upper slide plate 21 can be constructed in a raised structure of the frame 1, for example, by connecting it to a suspended slide rail.

[0082] Reference Figure 3 and Figure 4Both the upper sliding plate 21 and the lower sliding plate 22 are embedded with a plurality of crescent-shaped wheels 230 arranged along the sliding direction. When relative translation occurs between the upper sliding plate 21 and the lower sliding plate 22, the upper sliding plate 21 and / or the lower sliding plate 22 drive the crescent-shaped wheels 230 they carry to translate. Each crescent-shaped wheel 230 has at least one threading hole 231 for the thread 300 to pass through. In this embodiment, one threading hole 231 is used as an example. The two crescent-shaped wheels 230 distributed vertically are stacked to form a twisting wheel 23, and the center of the twisting wheel 23 is surrounded to form a core hole 232 for the core 400 to pass through. The specific forms of the thread 300 and the core 400 are as follows. Figure 1 .

[0083] Disassembling the thread-tightening wheel 23 as a whole, the thread-tightening wheel 23 includes a head 233, a tail 234, and a shaft 235. The head 233 and tail 234 are respectively fixed to both ends of the shaft 235 and protrude from both sides of the lower slide plate 22 and the entire lower slide plate 22. (Refer to...) Figure 2 and Figure 3 The tail portion 234 faces the area between the two screw-twisting mechanisms 2. A shaft portion 235 passes between the upper slide plate 21 and the lower slide plate 22. A screw-twisting gear 236 is provided on the peripheral side wall of the shaft portion 235, with each crescent wheel 230 having half of the screw-twisting gear 236. The screw-twisting gear 236 can be integrally formed with the shaft portion 235, or it can be fitted into the shaft portion 235 and then fixed. This embodiment uses integral forming as an example.

[0084] Reference Figure 3 and Figure 5 One of the upper slide plate 21 and the lower slide plate 22 has an embedded inner drive component 24. In this embodiment, the inner drive component 24 is embedded in the lower slide plate 22, and the inner drive component 24 is a rack that meshes with the wire-twisting gear 236. An inner drive mechanism 6 is fixed to the bottom of the lower slide plate 22, and the inner drive mechanism 6 moves together with the translation of the lower slide plate 22. The inner drive mechanism 6 can drive the inner drive component 24 to slide along the length of the lower slide plate 22, so as to drive the wire-twisting wheel 23 to rotate. In this way, the wire 300 will be wound around the wire core 400 on the side where the wire exits from the wire-twisting wheel 23. With the alternating changes in the position of the half-moon wheel 230 of the upper slide plate 21 and the lower slide plate 22, the same wire 300 can be wound back and forth on different wire cores 400 to weave a net. (Refer to...) Figure 2 The side of the wire-exiting wheel 23 is closer to the second floating mechanism 3.

[0085] In other embodiments, the inner drive component 24 may be mounted on the upper slide plate 21, in which case the inner drive mechanism 6 will also be mounted on the upper slide plate 21 accordingly.

[0086] Reference Figure 3 and Figure 5In this embodiment, the internal drive mechanism 6 includes a lead screw motor 61 and a drive block 62. The motor body of the lead screw motor 61 and the bearing seat corresponding to the lead screw are both fixed to the bottom of the lower slide plate 22. The drive block 62 is threadedly connected to the lead screw of the lead screw motor 61. One end of the drive block 62 passes through the lower slide plate 22 and is fixedly connected to the internal drive component 24.

[0087] In other embodiments, the internal drive mechanism 6 may also be a linear module, an electric cylinder module, a pneumatic cylinder, a hydraulic cylinder, etc. Any mechanism that can achieve linear drive should be considered within the scope of the internal drive mechanism 6 of this application.

[0088] Reference Figure 2 and Figure 3 Both the upper slide plate 21 and the lower slide plate 22 have two types of semicircular wheels 230. The first type of semicircular wheel 230 has a wire feed drum 4 for winding the wire 300 installed at one end. The wire feed drum 4 can rotate on its own and can rotate with the semicircular wheel 230. The second type of semicircular wheel 230 does not have a wire feed drum 4 installed. There are at least two second type semicircular wheels 230 and they are distributed at the beginning and end of the first type of semicircular wheel 230 in the direction of their arrangement.

[0089] For the semi-circular wheel 230 equipped with the feed spool 4, a mandrel 237 is fixed to its tail 234. In this embodiment, the mandrel 237 is fixed to the side wall of the tail 234 of the semi-circular wheel 230 by an angle steel for easy disassembly and replacement. In other embodiments, the mandrel 237 can also be directly welded to the tail 234 of the semi-circular wheel 230.

[0090] Reference Figure 6The feed cylinder 4 includes an outer cylinder 41 and an inner cylinder 42. One end of the outer cylinder 41 has a spherical guide head 411 and a connector 412. The maximum outer diameter of the spherical guide head 411 is larger than the outer diameter of the outer cylinder 41, and the maximum outer diameter of the connector 412 is smaller than the outer diameter of the outer cylinder 41. Thus, the drawn wire 300 always passes through the surface of the spherical guide head 411. The connector 412 is sleeved on the mandrel 237 of the output semi-circular wheel 230 and rotatably connected to the mandrel 237. The other end of the outer cylinder 41 is hollow and has an opening. The inner cylinder 42 is embedded in the open end of the outer cylinder 41. The outer cylinder 41 has an elastic element 43 embedded in it, which forces the inner cylinder 42 to have an outward tendency. The inner cylinder 42 is sleeved on the mandrel 237 of the other semi-circular wheel 230 and rotatably connected to it. Thus, when disassembling and assembling the wire feed spool 4, it is only necessary to press the inner cylinder 42 to separate it from the mandrel 237, making disassembly and assembly easy. In this embodiment, the elastic element 43 is exemplified by a spring. In other embodiments, if the sealing effect between the inner cylinder 42 and the outer cylinder 41 is good enough, the air between the inner cylinder 42 and the inner cavity of the outer cylinder 41 can also be regarded as the elastic element 43. That is, any structure or substance that can be compressed by pressing the inner cylinder 42, can force the inner cylinder 42 to return to its original position after the external force is removed, and can still maintain a certain preload after returning to its original position, should be considered within the scope of the elastic element 43 of this application.

[0091] Reference Figure 2 and Figure 7 The external drive mechanism 5 includes at least two drive units. In this embodiment, two drive units are used as an example. One drive unit drives two upper slide plates 21 synchronously, and the other drive unit drives two lower slide plates 22 synchronously.

[0092] The drive unit includes a drive source 51 and a rotating shaft 52. In this embodiment, the drive source 51 is a stepper motor, and its body is fixed to the frame 1. The rotating shaft 52 is mounted on the frame 1 via a bearing seat, and a driven gear 55 is fixed to the rotating shaft 52. The drive source 51 drives the driven gear 55 to rotate via gear transmission. Swing arms 53 are fixed to the peripheral sidewalls at both ends of the rotating shaft 52. The swing arms 53 swing with the rotation of the rotating shaft 52. A transition arm 54 is hinged to the sidewall at the end of the swing arm 53, and the transition arm 54 is hinged to the corresponding upper slide plate 21 or lower slide plate 22. In this embodiment, one of the swing arms 53 is integrally formed with the driven gear 55, serving as part of the driven gear 55. In other embodiments, the swing arm 53 may exist independently or the end face of the driven gear 55 may act as the swing arm 53. Thus, when the drive source 51 is started, the transition arm 54 will drive the upper slide plate 21 or lower slide plate 22 to reciprocate.

[0093] Reference Figure 2 and Figure 4When one of the upper slide plate 21 and the lower slide plate 22 translates relative to the frame 1, in order to avoid interference, the first floating unit 301 and the second floating unit 302 will correspondingly force the wire core 400 into the half hole of the core hole 232 corresponding to the other upper slide plate 21 or lower slide plate 22.

[0094] Reference Figure 2 and Figure 8 The first floating unit 301 includes a floating platform 31 and a floating module 32. The floating platform 31 has a shaft at each end, forming a rotatable connection with the frame 1, allowing the side of the floating platform 31 closest to the wire twisting mechanism 2 to swing relative to the frame 1. The floating module 32 transmits the translational force of the lower slide plate 22 to the floating platform 31, forcing the floating platform 31 to swing accordingly. Multiple straightening plates 311 are fixed to the surface of the floating platform 31, arranged along the sliding direction of the lower slide plate 22. Each straightening plate 311 is equipped with several straightening wheels 312. The wire core 400 passes between the straightening wheels 312. During swinging, the straightening wheels 312 apply lifting or pressing forces to the wire core 400.

[0095] Reference Figure 2 and Figure 9 The second floating unit 302 includes a bracket 33 mounted on the frame 1, a support frame 34 that can be raised and lowered along the bracket 33, and a floating module 32 that drives the support frame 34 to be raised and lowered.

[0096] The support 33 can be divided into two independent units. Each unit includes a base 331 and a vertical pole 332 fixed to the base 331. The two units are located on both sides of the woven mesh conveying path. The top of the vertical pole 332 is fixed with an end cap 333 with an outer diameter larger than the outer diameter of the vertical pole 332. The end cap 333 can be fixed by bolts screwed in along the axial direction of the vertical pole 332 for easy assembly and disassembly, or it can be directly welded.

[0097] The support frame 34 has sliders 341 fixed at both ends. The number of sliders 341 is determined according to the actual situation; in this embodiment, one slider is used at each end. The sliders 341 are sleeved on the upright 332 and slidably connected to the upright 332. An elastic body 334 is provided between the sliders 341 and the end cap 333. In this embodiment, the elastic body 334 is a spring, and the elastic body 334 is sleeved on the upright 332. The two ends of the elastic body 334 abut against the sliders 341 and the end cap 333 respectively, and are in a pre-compressed state, having the force to force the support frame 34 to move downward. In other embodiments, the two ends of the elastic body 334 can also be fixed to the sliders 341 and the end cap 333 respectively, and are in a pre-tensioned state.

[0098] The support frame 34 is hollow and has an opening for the woven net to pass through. A conveyor roller 342 is installed on the side where the net exits, and the conveyor roller 342 will support the woven net that passes through the opening.

[0099] Reference Figure 2 , Figure 9 and Figure 10 The specific structure of the floating module 32 is exemplified by its structure within the second floating unit 302. The floating module 32 includes an active member 321 and a driven member 322. The active member 321 is mounted on either the lower slide plate 22 or the upper slide plate 21; in this embodiment, it is mounted on the lower slide plate 22. The driven member 322 is mounted on the support frame 34. The active member 321 is located below the driven member 322 and abuts against the bottom surface of the driven member 322 in a supporting manner.

[0100] Reference Figure 9 and Figure 10 The driving element 321 includes a suspension seat 3211, a pin 3212, and a rotating sleeve 3213. The suspension seat 3211 is fixed to the lower slide plate 22 of the screw-tightening device 100. The pin 3212 is fixed to the suspension seat 3211 and has a cap 3214 at its end. The rotating sleeve 3213 is sleeved on the pin 3212 and is confined between the cap 3214 and the suspension seat 3211. The rotating sleeve 3213 can rotate relative to the pin 3212. If necessary, a bearing can be added between the rotating sleeve 3213 and the pin 3212. Thus, during the horizontal movement of the lower slide plate 22, the rotating sleeve 3213 will move horizontally along with it and roll relative to the bottom surface of the driven element 322.

[0101] The bottom surface of the follower 322 consists of alternating concave and flat surfaces with a smooth transition, which together form the track 3221. The pin 3212 is located below the follower 322, and the peripheral sidewall of the rotating sleeve 3213 abuts against the track 3221. When the rotating sleeve 3213 transitions from the flat area to the concave area, the support 34 descends accordingly; when the rotating sleeve 3213 transitions from the concave area to the flat area, the support 34 rises accordingly. This descent and ascent correspond to the required descent and ascent of the core 400.

[0102] In other embodiments, the track 3221 can be set on the active member 321, and the driven member 322 can be set as a column structure; or the active member 321 can be set above the driven member 322, and the direction of the force exerted by the corresponding elastic body 334 on the support 33 will be changed to upward, and the magnitude of the force is sufficient to suspend the support frame 34.

[0103] Reference Figure 2 , Figure 8 , Figure 10 and Figure 11The difference between the floating module 32 of the first floating unit 301 and the floating module 32 of the second floating unit 302 is that the peripheral sidewall of the rotating sleeve 3213 of the first floating unit 301 is spherical to match the angle change of the floating platform 31, so that the peripheral sidewall of the rotating sleeve 3213 always contacts the driving member 321 during the swinging process of the floating platform 31. The peripheral sidewall of the rotating sleeve 3213 of the second floating unit 302 is cylindrical.

[0104] The implementation principle of Example 1 is as follows:

[0105] The basically straight wire core 400 passes through the straightening wheel 312 of the first floating unit 301, the twisting wheel 23 of the two twisting mechanisms 2, and the support frame 34 of the second floating unit 302 in sequence.

[0106] The wire feed spool 4 containing the wire 300 is installed between the two wire twisting mechanisms 2. The wire 300 passes through the semi-circular wheel 230 of the downstream wire twisting mechanism 2 and is initially wound around the wire core 400.

[0107] As the wire core 400 is pulled downstream, the wire twisting mechanism 2 will continuously perform the following actions:

[0108] 1. The screwing wheel 23 is driven to rotate by the internal drive mechanism 6 and the internal drive component 24, so that the wire 300 is wound around the wire core 400 twice.

[0109] 2. The lower slide plate 22 is shifted by the distance of one screwing wheel 23, so that the crescent wheel 230 of the lower slide plate 22 coincides with the adjacent crescent wheel 230 of the original upper slide plate 21, realizing that the wire 300 crosses from the position of one wire core 400 to the position of the adjacent wire core 400. When the translation begins, the driving component 321 of the floating module 32 will drive the driven component 322 to rise, causing the floating platform 31 to flip up and the support frame 34 to move up, so as to lift the wire core 400 to the position of the core hole 232 corresponding to the crescent wheel 230 of the upper slide plate 21; when the lower slide plate 22 is about to reach the designated position, the floating platform 31 flips down and the support frame 34 descends to reset, and the wire core 400 descends to the position of the core hole 232 corresponding to the crescent wheel 230 of the lower slide plate 22.

[0110] 3. Rotate the screwing wheel 23 two more times to make the thread 300 wrap around the current core 400 twice.

[0111] 4. The upper slide plate 21 is shifted by the distance of one screwing wheel 23, so that the half-moon wheel 230 is further misaligned, so that the wire 300 crosses from the initial position of the wire core 400 to the position of the wire core 400 that is separated by one wire core 400.

[0112] 5. Rotate the screw wheel 23 two more times to make the thread 300 wrap around the current core 400 twice.

[0113] 6. The lower slide plate 22 and the upper slide plate 21 are reset in sequence and the silk thread 300 is wound around in the manner described above.

[0114] 7. Repeat the above steps to gradually weave a net.

[0115] Example 3:

[0116] Reference Figure 2 and Figure 12 A wire mesh weaving machine includes a wire twisting device 100 and a discharge device 200, the discharge device 200 being located downstream of the wire twisting device 100.

[0117] Reference Figure 12 and Figure 13 The discharge device 200 includes a base 7, a drive shaft 71 rotatably connected to the base 7, a drive component 8 that drives the drive shaft 71 to rotate, and several transmission gears 9 arranged axially on the drive shaft 71. The base 7 can be fitted with bearing seats for mounting the drive shaft 71 so that the drive shaft 71 can rotate around its axis. In this embodiment, the drive component 8 is a motor, and it is matched with a gear set to drive the drive shaft 71.

[0118] The transmission gear 9 includes a central gear 91 and side gears 92 distributed on both sides of the central gear 91. The side gears 92 have teeth 93 distributed circumferentially. The teeth 93 on both sides of the central gear 91 form grooves 94 with the outer circumferential surface of the central gear 91. During operation, the stiffer wire core 400 in the woven mesh passes through the grooves 94, and the teeth 93 on both sides of the grooves 94 respectively embed into the adjacent mesh openings on both sides of the wire core 400. Thus, the transmission gear 9 provides traction to the woven mesh during rotation.

[0119] Example 4:

[0120] A method for weaving wire mesh includes the following steps:

[0121] a. Select the silk thread 300, which is easier to bend, and the silk core 400, which has a relatively higher hardness than the silk thread 300;

[0122] b. Arrange multiple filament cores 400 in parallel and continuously convey them along the length direction. The conveying action can be achieved by the discharge device 200 of Example 3.

[0123] Each filament 300 moves back and forth along the arrangement direction of the filament core 400, passing through at least two filament cores 400 during the movement, and winding around at least one turn after passing through each filament core 400; adjacent filaments 300 change position during the back-and-forth movement and rotation winding between filament cores 400, so that at least two different filaments 300 are distributed in the area between adjacent filament cores 400; this action can be achieved by the wire twisting device 100 in embodiment 2.

[0124] During the above process, the core 400 does not undergo any undesirable bending. It should be noted that "any undesirable bending" here refers to the fact that the core 400 is not intended to be bent or folded during the manufacturing process; the core 400 should be kept as straight as possible during manufacturing. Slight bending caused by the fluctuations of the floating mechanism 3, slight bending caused by the core 400's own weight, and slight bending caused by the pulling of the thread 300 are all within the expected range and do not fall under the category of "any undesirable bending."

[0125] 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.
