Description

Technical Field

[0001] This application relates to equipment for processing reinforcing mesh, and more particularly to a reinforcing mesh welding machine. This application also relates to a reinforcing mesh production line. Background Technology

[0002] Reinforcing mesh is a mesh in which longitudinal and transverse reinforcing bars are arranged at certain intervals and perpendicular to each other, with all intersections welded together. It is widely used in beams, columns, floor slabs, roofs, walls, concrete pavements, bridge decks, airport runways, tunnel linings, box culverts, dock floors, and precast components in industrial and civil buildings. In recent years, with the rapid advancement of national infrastructure projects, the demand for reinforcing mesh has increased significantly.

[0003] Traditional steel mesh production typically relies on machines to straighten and cut the steel bars, followed by manual arrangement and welding. This method is labor-intensive, inefficient, and yields inconsistent weld quality. To improve production efficiency, steel mesh welding is now often performed on specialized welding machines, capable of producing high-quality meshes with different wire diameters and mesh counts. During welding, the straightened and cut longitudinal steel bars are first arranged at specific intervals and simultaneously fed between the upper and lower welding electrodes of the welding machine. Then, the transverse steel bars are fed to predetermined positions on the longitudinal bars. The intersections of the transverse and longitudinal steel bars are welded together using the coordinated action of the upper and lower welding electrodes.

[0004] In existing steel mesh welding machines, the transverse reinforcing bars are fed onto the longitudinal reinforcing bars via a fixed path, and typically all transverse reinforcing bars are located above the longitudinal reinforcing bars. After the steel mesh is welded, all transverse reinforcing bars are located on the same side of the longitudinal reinforcing bars. When the steel mesh is bent laterally, the spacing between the longitudinal reinforcing bars can change with the bending of the transverse reinforcing bars, resulting in poor transverse bending strength of the steel mesh. Summary of the Invention

[0005] To improve the transverse bending strength of steel mesh, this application provides a steel mesh welding machine and production line.

[0006] The steel mesh welding machine provided in this application adopts the following technical solution: A steel mesh welding machine includes a longitudinal steel bar feeding device, a first transverse steel bar feeding device, a second transverse steel bar feeding device, and a welding device. The longitudinal steel bar feeding device is arranged opposite to the welding device and can simultaneously feed multiple longitudinal steel bars into the welding device. The first transverse steel bar feeding device is arranged above the welding device and can feed transverse steel bars above the longitudinal steel bars. The second transverse steel bar feeding device is arranged to the side of the welding device and can feed transverse steel bars below the longitudinal steel bars. The welding device can weld the transverse steel bars onto the longitudinal steel bars to form a steel mesh.

[0007] By adopting the above technical solution, the first transverse steel bar feeding device can transport the transverse steel bar above the longitudinal steel bar, and the second transverse steel bar feeding device can transport the transverse steel bar below the longitudinal steel bar, so that the transverse steel bar can be distributed on the upper and lower sides of the longitudinal steel bar, forming a fixation on the longitudinal steel bar from both sides, thereby improving the transverse bending strength of the steel mesh.

[0008] In one specific implementation, the longitudinal rebar feeding device includes a longitudinal rebar feeding seat, a longitudinal rebar positioning frame, a longitudinal rebar feeding mechanism, a distributor moving mechanism, and a first rebar distributor. The longitudinal rebar feeding seat is located at one end of the welding device. The longitudinal rebar positioning frame is located on the longitudinal rebar feeding seat and can position multiple longitudinal rebars and pass them to the longitudinal rebar feeding mechanism. The longitudinal rebar feeding mechanism is located inside the longitudinal rebar feeding seat and can simultaneously transport multiple longitudinal rebars to the welding device. The distributor moving mechanism includes a distributor moving guide rail, a distributor moving seat, and a distributor moving drive structure. The distributor moving guide rail is fixed on the longitudinal rebar feeding seat and is perpendicular to the longitudinal rebars. The distributor moving seat is mounted on the distributor moving guide rail and can move along the distributor moving guide rail under the drive of the distributor moving drive structure. The first rebar distributor is fixed on the distributor moving seat and can distribute the longitudinal rebars one by one to the longitudinal rebar positioning frame.

[0009] By adopting the above technical solution, the spacing between different longitudinal steel bars can be easily controlled by the longitudinal steel bar positioning frame, and the steel bar feeding mechanism can be used to transmit the steel bars synchronously to the welding device; the first steel bar distributor can extract a single steel bar from multiple longitudinal steel bars and distribute it one by one; the distributor moving seat can realize the lateral movement of the first steel bar distributor, thereby distributing the single longitudinal steel bar to different positions on the longitudinal steel bar positioning frame.

[0010] In one specific implementation, the longitudinal rebar positioning frame includes a movable positioning frame and a fixed positioning frame. The movable positioning frame and the fixed positioning frame are spaced apart on the longitudinal rebar feeding seat, with the movable positioning frame located at both ends of the longitudinal rebar feeding seat. The movable positioning frame includes a movable support, a movable positioning plate, and a movable propulsion structure. The movable support is laterally positioned on the longitudinal rebar feeding seat and can move longitudinally on the longitudinal rebar feeding seat under the drive of the movable propulsion structure. The movable positioning plate is fixed to the movable support and has multiple movable positioning slots spaced apart on it. The fixed positioning frame includes a fixed support, a fixed positioning plate, a rebar support frame, a rebar support rod, and a support frame propulsion structure. The fixed support is laterally fixed to the longitudinal rebar feeding seat, and the fixed positioning plate is fixed to the… On the fixed support, a plurality of fixed positioning slots are spaced apart on the fixed positioning plate. The rebar support frame is located on one side of the fixed support and can move laterally under the drive of the support frame propulsion structure. The rebar support rod is fixed on the rebar support frame and is correspondingly arranged with the fixed positioning slots. The longitudinal rebar feeding mechanism is located in the longitudinal rebar feeding seat and includes a feeding guide rail, a feeding moving seat, and a longitudinal rebar clamping frame. The feeding guide rail is arranged towards the welding device. The feeding moving seat is installed on the feeding guide rail and can move along the feeding guide rail. The longitudinal rebar clamping frame is fixed on the feeding moving seat. A plurality of rebar clamps are arranged on the longitudinal rebar clamping frame. The plurality of rebar clamps are correspondingly arranged with the plurality of moving positioning slots one by one, and the height of the rebar clamps is lower than the height of the moving support.

[0011] By adopting the above technical solution, the moving propulsion structure can drive the moving positioning frame to transfer one end of the longitudinal steel bar to the longitudinal steel bar feeding mechanism; the steel bar support rod corresponding to the fixed positioning groove and the support frame propulsion structure can support the longitudinal steel bar distributed by the first steel bar distributor on the upper part of the fixed positioning groove, and when the longitudinal steel bar is conveyed to the longitudinal steel bar feeding mechanism, the steel bar support rod is moved aside, so that the longitudinal steel bar falls into the bottom of the fixed positioning groove, realizing the separation of the distributed longitudinal steel bar and the feeding longitudinal steel bar, which is conducive to the simultaneous feeding and distribution of longitudinal steel bars; the setting of the feeding guide rail and the feeding moving seat can drive the longitudinal steel bar clamping frame to move towards the welding device, realizing the synchronous feeding of longitudinal steel bars and the positioning of transverse steel bars at different positions of the longitudinal steel bar; the multiple steel bar clamps set on the longitudinal steel bar clamping frame can realize the clamping and synchronous transmission of multiple longitudinal steel bars, realizing the propulsion and transmission of longitudinal steel bars and welded steel mesh semi-finished products.

[0012] In one specific implementation, the first transverse rebar feeding device includes a second rebar distributor and a transverse rebar guiding structure. The second rebar distributor can distribute the transverse rebars one by one to the transverse rebar guiding structure. The transverse rebar guiding structure is disposed between the second rebar distributor and the welding device, and can guide the transverse rebars to a set position above the longitudinal rebars in the welding device.

[0013] By adopting the above technical solution, the second rebar distributor can extract individual rebars from multiple transverse rebars and distribute them one by one to the transverse rebar guide structure, realizing automatic single-bar distribution of transverse rebars; the transverse rebar guide structure can guide the transverse rebars to a set position above the longitudinal rebars, thereby enabling the transverse rebars to be welded above the longitudinal rebars, realizing automatic feeding and precise positioning of transverse rebars, improving the quality and production efficiency of rebar mesh.

[0014] In one specific implementation, the second transverse rebar feeding device includes a third rebar distributor, a transverse rebar feeding mechanism, and a transverse rebar transfer mechanism. The third rebar distributor is located on the side of the welding device and can distribute the transverse rebars one by one to the transverse rebar feeding mechanism. The transverse rebar feeding mechanism extends from the third rebar distributor to the welding device. The transverse rebar feeding mechanism includes a feeding wheel frame and a plurality of feeding wheels arranged on the feeding wheel frame. The feeding wheels can rotate under the drive of the drive structure. The transverse rebar transfer mechanism is located between the transverse rebar feeding mechanism and the welding device and can transfer the transverse rebars on the transverse rebar feeding mechanism to a set position below the longitudinal rebar.

[0015] By adopting the above technical solution, the third rebar distributor can extract single rebars from multiple transverse rebars and distribute them one by one to the transverse rebar feeding mechanism, thereby realizing automatic feeding of single transverse rebars; the transverse rebar transfer mechanism can transfer the transverse rebars to a set position below the longitudinal rebars in the welding device, so as to facilitate the welding of transverse rebars below the longitudinal rebars and ensure the quality of the welded rebar mesh.

[0016] In one specific implementation, the welding device includes a longitudinal rebar guide frame, a lower welding table, an upper welding table, and a mesh moving output mechanism. The longitudinal rebar guide frame is disposed on the side of the lower and upper welding tables adjacent to the longitudinal rebar feeding device. The longitudinal rebar guide frame includes a lifting frame and a plurality of longitudinal rebar guide tubes disposed on the lifting frame. One end of each longitudinal rebar guide tube is formed into a trumpet-shaped guide end, and the guide end faces the longitudinal rebar feeding device. The lower welding table includes a lower welding table lifting seat and a plurality of lower welding electrodes disposed on the lower welding table lifting seat. The upper welding table includes an upper welding table mounting frame, an upper electrode lifting structure, and upper welding electrodes. The upper welding table mounting frame is fixedly disposed. A plurality of upper welding electrodes are disposed, and the plurality of upper welding electrodes are mounted on the upper welding table mounting frame through the upper electrode lifting structure and are disposed opposite to the lower welding electrodes. The mesh moving output mechanism is disposed on the opposite side of the longitudinal rebar feeding device and is capable of driving the rebar mesh to move away from the longitudinal rebar feeding device.

[0017] By adopting the above technical solution, multiple longitudinal steel bar guide pipes installed on the lifting frame can guide and position multiple longitudinal steel bars, transporting them to designated positions on the upper and lower welding platforms respectively, ensuring the welding quality of the steel mesh. The lifting frame can also be used to adjust the height of the longitudinal steel bars, facilitating the transport and positioning of transverse steel bars below the longitudinal steel bars. The lower welding platform lifting seat allows adjustment of the distance between the longitudinal steel bars and the lower welding electrode, facilitating the transport of transverse steel bars to designated positions on the lower welding electrode. The upper electrode lifting structure drives the upper welding electrode to move towards the lower welding electrode, pressing the transverse and longitudinal steel bars together, facilitating a strong weld between them. The coordination of the mesh moving output mechanism and the longitudinal steel bar feeding device enables longitudinal movement of the longitudinal steel bars and the steel mesh, controlling the welding spacing of the transverse steel bars on the longitudinal steel bars.

[0018] In one specific implementation, the mesh moving output mechanism includes a mesh output frame, an output moving base, and an output mesh clamp. The output moving base is mounted on the mesh output frame and is capable of moving longitudinally on the mesh output frame. The output mesh clamp is disposed on the output moving base.

[0019] By adopting the above technical solution, the mesh output frame can carry the steel mesh, allowing the steel mesh to move on the mesh output frame; the output mesh clamp can fix and loosen the steel mesh; the output moving seat can drive the output mesh clamp, and the output mesh clamp can pull the steel mesh to move longitudinally, controlling the welding spacing of the transverse steel bars on the longitudinal steel bars, and realizing the output of the welded steel mesh.

[0020] In one specific implementation, the first, second, and third rebar distributors each include a distributor frame, a rebar storage trough, a rebar output roller, a rebar distributing roller, and a blocking structure. The rebar storage trough is located on the upper part of the distributor frame and has rebar length limiting plates on both sides. The rebar output roller is located at the outlet of the rebar storage trough and can guide the rebar between the rebar output roller and the rebar distributing roller. The rebar distributing roller includes a distributing roller shaft, a distributing motor, a distributing guide wheel, and a distributing wheel. The distributing roller shaft is mounted on the distributor frame and can rotate under the drive of the distributing motor. The distributing guide wheel and the distributing wheel are fixed at intervals on the distributing roller shaft. The distributing wheel has a material clamping groove around its periphery. The blocking structure can temporarily block and store the rebar output by the rebar distributing roller.

[0021] By adopting the above technical solutions, the rebar storage trough can store multiple rebars, reducing the frequency of rebar feeding and the reliance on manual labor during automatic welding of rebar mesh; the clamping grooves set around the distributing wheel can clamp individual rebars, enabling the transfer and release of individual rebars; the distributing guide wheel can guide the movement of rebars, achieving smooth output of individual rebars; and the baffle structure can temporarily store and buffer individual output rebars, ensuring rapid and reliable output of rebars.

[0022] In one specific implementation, the rebar output roller includes an output roller shaft, an output motor, output guide wheels, and a magnetic output wheel. The output roller shaft is mounted on the feeder frame and can rotate under the drive of the output motor. The output guide wheels are fixed at intervals at the outlet of the rebar storage tank and surround the outer periphery of the output roller shaft. The magnetic output wheel is fixed on the output roller shaft between the output guide wheels, and magnetic elements are spaced around the periphery of the magnetic output wheel.

[0023] By adopting the above technical solution, the magnetic elements spaced around the magnetic output wheel can attract a small amount of steel bars in the steel bar storage tank. The rotation of the magnetic output wheel will output the small amount of steel bars between the steel bar output roller and the steel bar distribution roller. While ensuring that there are steel bars between the steel bar output roller and the steel bar distribution roller, the number of steel bars between the steel bar output roller and the steel bar distribution roller is reduced, the pressing and entanglement between steel bars is reduced, and the steel bars are ensured to be distributed and conveyed by the distribution roller in a single bar manner.

[0024] The steel mesh production line provided in this application adopts the following technical solution: A steel mesh production line includes a slicing device and a steel mesh welding machine provided in this application. The slicing device is disposed on the discharge side of the welding device. The slicing device includes a mesh feeding mechanism and a cutting mechanism. The mesh feeding mechanism is disposed across the cutting mechanism. The mesh feeding mechanism includes a feeding transfer frame, a movable base, a lifting column, a gripper frame, and grippers. The movable base is mounted on the feeding transfer frame and can move along the feeding and discharging direction of the cutting mechanism. The lifting column is mounted on the movable base and can move up and down on the movable base. The gripper frame is fixed to the lower part of the lifting column. There are multiple grippers, and the multiple grippers are fixed on the gripper frame.

[0025] By adopting the above technical solution, multiple grippers fixed on the gripper frame can be used to stably grip the steel mesh; the movable base and lifting column can be used to lift and move the steel mesh, thereby conveying the steel mesh into the set position in the cutting mechanism, cutting the steel mesh to the set length, and conveying the cut residue of the set length to the discharge side of the cutting mechanism.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By using the first transverse steel bar feeding device and the second transverse steel bar feeding device, transverse steel bars can be fed to the top and bottom of the longitudinal steel bars respectively, thereby forming a welded connection with the transverse steel bars at the set positions above and below the longitudinal steel bars. The transverse steel bars restrict the longitudinal steel bars from both the top and bottom, thereby improving the transverse bending strength of the steel mesh and the reliability of the welded connection. 2. The longitudinal steel bar feeding device can feed multiple longitudinal steel bars simultaneously, ensuring the welding position of the transverse steel bars on different longitudinal steel bars, and can simultaneously weld at multiple intersections of the transverse steel bars and multiple longitudinal steel bars, thereby improving the welding efficiency of the steel mesh. 3. Multiple rebar feeders can be used to separate longitudinal and transverse rebars, enabling the single output of multiple rebars from the rebar storage tank. This ensures the parallel positioning and arrangement of single longitudinal rebars and the separate feeding of single transverse rebars, thereby improving the structural stability of the rebar mesh. 4. The slicing device can cut large pieces of steel mesh into multiple meshes of a set size, thus making it easy to obtain steel meshes of various sizes, reducing the need to adjust the parameters of the steel mesh welding machine, and improving the production efficiency of steel mesh.

Detailed Implementation

[0041] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0042] In this application, unless otherwise stated, the directional terms such as "longitudinal" and "lateral" indicate the orientation or positional relationship based on the orientation or positional relationship of the reinforcing mesh during movement in the reinforcing mesh welding machine of this application. Specifically, "longitudinal" refers to the direction of movement of the reinforcing mesh in this application, and "lateral" refers to the direction perpendicular to "longitudinal" on the horizontal plane. The description of the orientation or positional relationship of the reinforcing mesh welding machine and its components in this application is consistent with their actual installation orientation in use.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this specification, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first,” “second,” or “third” may explicitly or implicitly include one or more of the stated features.

[0045] One embodiment of the steel mesh welding machine of this application is as follows: Figure 1 As shown, it includes a longitudinal steel bar feeding device 1, a first transverse steel bar feeding device 2, a second transverse steel bar feeding device 3, and a welding device 4.

[0046] The welding device 4 is capable of welding multiple transversely arranged welding points sequentially or simultaneously, while the longitudinal rebar feeding device 1 is longitudinally positioned adjacent to the welding device 4. The longitudinal rebar feeding device 1 can simultaneously convey multiple spaced longitudinal rebars, allowing them to be synchronously fed towards the welding device 4 and enter multiple welding point positions within the welding device 4.

[0047] The first transverse rebar feeding device 2 is positioned above the welding device 4, capable of conveying the transverse rebar to the welding device 4 and reaching a position above the longitudinal rebar spanning multiple welding points. Thus, through the welding operation of the welding device 4, the transverse rebar can be welded from above the longitudinal rebar to multiple longitudinal rebars, forming a welded connection between the longitudinal and transverse rebars.

[0048] The second transverse rebar feeding device 3 is located on one side of the welding device 4 and is arranged transversely to the welding device 4. It can transmit transverse rebars from one side of the welding device 4 into the welding device, reaching a position below the longitudinal rebars that spans multiple welding points. In this way, the welding operation of the welding device 4 can weld the transverse rebars from below the longitudinal rebars to multiple longitudinal rebars, forming a welded connection between the longitudinal and transverse rebars.

[0049] After the welding device 4 completes the welding between one transverse steel bar and multiple longitudinal steel bars, it can be conveyed by the longitudinal steel bar feeding device 1, or driven by the output mechanism of the welding device 4 to move multiple longitudinal steel bars synchronously longitudinally by a set distance. Then, a new transverse steel bar is input through the first transverse steel bar feeding device 2 or the second transverse steel bar feeding device 3, and the welding device 4 welds the transverse steel bar onto the longitudinal steel bar.

[0050] In this way, a transverse steel bar can be welded at predetermined intervals to multiple longitudinal steel bars with a certain spacing, forming a steel mesh composed of longitudinal and transverse steel bars welded together. Some of the transverse steel bars are fed by a first transverse steel bar feeding device 2 and welded above the longitudinal steel bars, while some are fed by a second transverse steel bar feeding device 3 and welded below the longitudinal steel bars. Typically, a certain number of transverse steel bars are fed alternately by the first and second transverse steel bar feeding devices 2 and 3, forming a steel mesh with transverse steel bars alternately welded above and below the longitudinal steel bars. In this steel mesh, the transverse steel bars restrict the distance between the longitudinal steel bars from both above and below, effectively improving the transverse bending strength of the steel mesh.

[0051] In some embodiments of the steel mesh welding machine of this application, such as Figures 2 to 4 As shown, the longitudinal rebar feeding device 1 includes a longitudinal rebar feeding seat 11, a longitudinal rebar positioning frame 12, a longitudinal rebar feeding mechanism 13, a distributor moving mechanism 14, and a first rebar distributor 15.

[0052] The longitudinal steel bar feed seat 11 is fixedly installed at the longitudinal steel bar feed end of the welding device 4, in a position opposite to the longitudinal direction of the welding device 4. The longitudinal steel bar feed seat 11 is usually a frame structure made of metal material.

[0053] The longitudinal rebar positioning frame 12 is installed on the longitudinal rebar feeding seat 11. Multiple longitudinal rebar positioning structures are arranged at different positions on the longitudinal rebar positioning frame 12. Each positioning structure can position one longitudinal rebar, thus positioning multiple longitudinal rebars separately. This ensures that the lateral positions of the multiple longitudinal rebars correspond one-to-one with the positions of multiple welding points of the welding device 4. The longitudinal rebar positioning frame 12 can also transfer multiple longitudinal rebars located on it to the longitudinal rebar feeding mechanism 13, facilitating the continued feeding of the longitudinal rebars by the longitudinal rebar feeding mechanism 13.

[0054] The longitudinal steel bar feeding mechanism 13 is installed inside the longitudinal steel bar feeding seat 11, usually located below the longitudinal steel bar positioning frame 12. It is used to receive multiple longitudinal steel bars from the longitudinal steel bar positioning frame 12 and simultaneously transport the multiple longitudinal steel bars to the welding device 4. Each longitudinal steel bar passes through a welding point in the welding device 4.

[0055] The material distributor moving mechanism 14 includes a material distributor moving guide rail 141, a material distributor moving seat 142, and a material distributor moving drive structure 143. The material distributor moving guide rail 141 is fixed on the longitudinal rebar feed seat 11. Typically, the material distributor moving guide rail 141 is perpendicular to the feeding direction of the longitudinal rebar, that is, parallel to the arrangement direction of the multiple welding points in the welding device 4. The material distributor moving seat 142 is mounted on the material distributor moving guide rail 141 and can slide on the material distributor moving guide rail 141. The material distributor moving drive structure 143 is disposed between the material distributor moving seat 142 and the longitudinal rebar feed seat 11. The material distributor moving drive structure 143 can be any drive structure capable of driving the material distributor moving seat 142 to move on the material distributor moving guide rail 141, such as a screw drive structure, a wheel-rail drive structure, or a gear and rack structure.

[0056] The first rebar distributor 15 is fixed on the distributor moving seat 142 and can move along the longitudinal rebar positioning frame 12 together with the distributor moving seat 142. The first rebar distributor 15 can extract a single longitudinal rebar from multiple longitudinal rebars and distribute it one by one to different positions on the longitudinal rebar positioning frame 12, so as to realize the positioning of each longitudinal rebar at different positions on the longitudinal rebar positioning frame 12.

[0057] As a preferred embodiment of the steel mesh welding machine of this application, such as Figure 3 and Figure 4 As shown, the longitudinal rebar positioning frame 12 includes a movable positioning frame 121 and a fixed positioning frame 122. The movable positioning frame 121 and the fixed positioning frame 122 are arranged at intervals on the longitudinal rebar feeding seat 11. Typically, the movable positioning frame 121 is located at both ends of the longitudinal rebar feeding seat 11, while the fixed positioning frame 122 is located in the middle of the longitudinal rebar feeding seat 11, between the fixed positioning frames 122 at both ends.

[0058] The movable positioning frame 121 includes a movable support 1211, a movable positioning plate 1212, and a movable propulsion structure 1213. The movable support 1211 is a metal support laterally arranged on both sides of the longitudinal rebar feed seat 11. Both ends of the movable support 1211 are mounted on the longitudinal rebar feed seat 11 and can move longitudinally along the longitudinal rebar feed seat 11. The movable propulsion structure 1213 is disposed between the movable support 1211 and the longitudinal rebar feed seat 11. The movable propulsion structure 1213 typically uses a pneumatic or hydraulic cylinder, but can also use other linear propulsion structures such as an electric push rod. Through the operation of the movable propulsion structure 1213, the movable support 1211 can be driven to move longitudinally on the longitudinal rebar feed seat 11. The movable positioning plate 1212 is fixed to the movable support 1211. Multiple movable positioning slots 1214 are spaced apart on the edge of the movable positioning plate 1212 away from the movable support 1211. The distance between the multiple movable positioning slots 1214 is set according to the spacing between the longitudinal rebars required by the rebar mesh.

[0059] When the first rebar distributor 15 distributes the longitudinal rebars to the longitudinal rebar positioning frame 12, both ends of the longitudinal rebars are located on the movable positioning frames 121 at both ends of the longitudinal rebar feed seat 11, and the end of each longitudinal rebar is located in a movable positioning groove 1214. By controlling the movable propulsion structure 1213 to push the movable support 1211 towards the end of the longitudinal rebar, the end of the longitudinal rebar can slide off the movable positioning frame 121 and reach the longitudinal rebar feeding mechanism 13, where it will be further fed.

[0060] The fixed positioning frame 122 includes a fixed bracket 1221, a fixed positioning plate 1222, a rebar support frame 1223, a rebar support rod 1224, and a support frame pushing structure 1225. The fixed bracket 1221 is horizontally arranged across both sides of the longitudinal rebar feed seat 11 and is fixed at different positions on the longitudinal rebar feed seat 11 at intervals. The fixed positioning plate 1222 is fixed to the fixed bracket 1221 and its free end extends upward. Multiple fixed positioning grooves 1226 are provided at intervals on the upper edge of the fixed positioning plate 1222. The distance between the multiple fixed positioning grooves 1226 is the same as the distance between the movable positioning grooves 1214, and they are corresponding to the movable positioning grooves 1214.

[0061] The rebar support frame 1223 is disposed on one side of the fixed bracket 1221 and is arranged parallel to the fixed bracket 1221. The two ends of the rebar support frame 1223 are slidably connected to both sides of the longitudinal rebar feed seat 11. In one specific embodiment, one end of the rebar support frame 1223 is installed on one side of the longitudinal rebar feed seat 11 through the cooperation of a sliding rod and a sliding seat, and the other end is connected to the support frame propulsion structure 1225 installed on the other side of the longitudinal rebar feed seat 11. The support frame propulsion structure 1225 is usually a propulsion cylinder or a propulsion hydraulic cylinder. When the support frame propulsion structure 1225 is activated, it can drive the rebar support frame 1223 to move laterally.

[0062] The reinforcing bar support rod 1224 is fixed to the reinforcing bar support frame 1223. The number of reinforcing bar support rods 1224 is the same as the number of fixed positioning slots 1226, and their fixed positions correspond longitudinally to the positions of the fixed positioning slots 1226. When the first reinforcing bar distributor 15 distributes the longitudinal reinforcing bars into the fixed positioning slots 1226, the reinforcing bar support rod 1224 can support the longitudinal reinforcing bars, preventing them from directly entering the bottom of the fixed positioning slots 1226. The reinforcing bar support rod 1224 can deviate from its position relative to the fixed positioning slots 1226 as the reinforcing bar support frame 1223 moves laterally, causing the longitudinal reinforcing bars to lose support and fall into the bottom of the fixed positioning slots 1226. Through the movement of the movable positioning frame 121, one end of the longitudinal reinforcing bar is transmitted to the longitudinal reinforcing bar feeding mechanism 13, which synchronously pulls multiple longitudinal reinforcing bars. At this time, the reinforcing bar support rod 1224 can return to its position relative to the fixed positioning slots 1226 by the lateral movement of the reinforcing bar support frame 1223. In this way, the first rebar distributor 15 can be controlled to feed a new round of longitudinal rebars, and the newly fed longitudinal rebars are blocked at the top of the fixed positioning groove 1226 by the rebar support rod 1224, so as to separate them from the longitudinal rebars pulled by the longitudinal rebar feeding mechanism 13. This prevents the longitudinal rebars from moving due to the pull of the longitudinal rebar feeding mechanism 13 on the longitudinal rebars, so that the longitudinal rebars required for the next rebar mesh can be fed while the previous rebar mesh is being welded, saving the time waiting for the longitudinal rebars to be fed and improving the production efficiency of the rebar mesh.

[0063] The longitudinal rebar feeding mechanism 13 includes a feeding guide rail 131, a feeding moving seat 132, and a longitudinal rebar clamping frame 133. The feeding guide rail 131 is located inside the longitudinal rebar feeding seat 11 and below the longitudinal rebar positioning frame 12. The feeding guide rail 131 is longitudinally oriented towards the welding device 4. The feeding moving seat 132 is mounted on the feeding guide rail 131 and can slide longitudinally on it. The longitudinal rebar clamping frame 133 is fixed to the feeding moving seat 132. Multiple rebar clamps 134 are provided on the longitudinal rebar clamping frame 133. The number of rebar clamps 134 is the same as the number of moving positioning slots 1214, and their lateral positions correspond to the positions of the moving positioning slots 1214. The rebar clamps 134 typically use pneumatic grippers, and the opening of the gripper is upward-facing.

[0064] When the movable support 1211 moves longitudinally under the push of the movable propulsion structure 1213, the ends of the longitudinal steel bars fall off the movable support 1211 and fall into the openings of multiple steel bar clamps 134. By controlling the movement of the steel bar clamps 134, multiple longitudinal steel bars can be clamped and fixed. The feeding movable seat 132 moves towards the welding device 4 under the drive of the drive structure, simultaneously pushing multiple longitudinal steel bars towards the welding device 4. The feeding movable seat 132 stops after advancing a set distance, and a transverse steel bar is welded onto the longitudinal steel bar to perform the welding of the steel mesh. The height of the steel bar clamps 134 is lower than the height of the movable positioning frame 121, allowing the steel bar clamps 134 to move downwards towards the welding device 4 via the movable positioning frame 121, reaching a position close to the welding device 4.

[0065] In some embodiments of the steel mesh welding machine of this application, such as Figure 5 As shown, the first transverse rebar feeding device 2 includes a second rebar distributor 21 and a transverse rebar guiding structure 22. The second rebar distributor 21 is positioned above the welding device 4 and can individually feed multiple transverse rebars onto the transverse rebar guiding structure 22. The transverse rebar guiding structure 22 is positioned between the second rebar distributor 21 and the welding device 4. The transverse rebar guiding structure 22 has a guide edge extending towards the welding point position in the welding device 4. The transverse rebars can slide smoothly along the guide edge of the transverse rebar guiding structure 22 to reach the set positions at multiple welding points within the welding device 4, and be positioned above the longitudinal rebars. Thus, through the operation of the welding device 4, the transverse rebars can be welded above the longitudinal rebars, forming a welded connection between the transverse rebars and multiple longitudinal rebars.

[0066] In a preferred embodiment of the steel mesh welding machine of this application, such as Figure 6As shown, the second transverse rebar feeding device 3 includes a third rebar distributor 31, a transverse rebar feeding mechanism 32, and a transverse rebar transfer mechanism 33. The third rebar distributor 31 is located on the side of the welding device 4 and can extract a single transverse rebar from multiple transverse rebars and distribute it to the transverse rebar feeding mechanism 32 as needed. The transverse rebar feeding mechanism 32 extends from the lower side of the third rebar distributor 31 into the interior of the welding device 4 and is used to transfer the transverse rebars distributed by the third rebar distributor 31 into the welding device.

[0067] The transverse rebar feeding mechanism 32 includes a feeding wheel frame 321 and feeding wheels 322. The feeding wheel frame 321 extends from the second transverse rebar feeding device 3 towards the welding device 4 and enters the vicinity of the welding point inside the welding device 4. Multiple feeding wheels 322 are spaced apart on the feeding wheel frame 321 and can rotate synchronously under the drive of the feeding wheel drive structure. Feeding grooves are provided on the feeding wheels 322. The transverse rebars fed by the third rebar distributor 31 fall into the feeding grooves on the feeding wheels 322. When the feeding wheels 322 rotate, they can convey the transverse rebars into the welding device 4. Transverse rebar positioning plates are provided at relatively opposite positions inside the welding device 4. These positioning plates can block the transverse rebars conveyed by the transverse rebar feeding mechanism 32, limiting the conveying position of the transverse rebars.

[0068] The transverse rebar transfer mechanism 33 is installed inside the welding device 4 and located between the transverse rebar feeding mechanism 32 and the welding point of the welding device 4. A transverse rebar transfer mechanism 33 is described as follows: Figure 7 As shown, the device includes a transverse rebar turning shaft 331, transverse rebar turning claws 332, and a turning motor 333. One end of the transverse rebar turning shaft 331 is rotatably connected to one side of the welding device 4, and the other end is connected to the turning motor 333, which is fixed to the other side of the welding device 4. Multiple transverse rebar turning claws 332 are fixed at intervals on the transverse rebar turning shaft 331. Several lifting discharge plates 34 are arranged between the feeding wheels 322 inside the welding device 4. After the longitudinal rebar is fed, and the transverse rebar on the feeding wheel 322 reaches the transverse rebar positioning plate, the lifting discharge plate 34 rises, pushing the transverse rebar out of the feeding groove of the feeding wheel 322. The transverse rebar slides along the top of the lifting discharge plate 34 into the transverse rebar turning claw 332. The turning motor 333 rotates, driving the transverse rebar turning claw 332 to turn to the welding point of the welding device 4. The transverse rebar then exits from the transverse rebar turning claw 332 and falls into the welding point below the longitudinal rebar.

[0069] In some embodiments of the steel mesh welding machine of this application, such as Figure 8 and Figure 9As shown, the welding device 4 includes a longitudinal steel bar guide frame 41, a lower welding table 42, an upper welding table 43, and a mesh moving output mechanism 44.

[0070] The longitudinal steel bar guide frame 41 is set between the lower welding platform 42 and the upper welding platform 43 and the longitudinal steel bar feeding device 1. Multiple longitudinal steel bars conveyed by the longitudinal steel bar feeding device 1 are guided by the longitudinal steel bar guide frame 41 to the welding point between the lower welding platform 42 and the upper welding platform 43.

[0071] The longitudinal rebar guide frame 41 includes a lifting frame 411 and longitudinal rebar guide pipes 412. The lifting frame 411 is arranged laterally and can be raised and lowered under the drive of the lifting mechanism. There are multiple longitudinal rebar guide pipes 412, which are fixed at intervals on the lifting frame 411 and can be raised and lowered with the lifting frame 411. The end of the longitudinal rebar guide pipe 412 facing the longitudinal rebar feeding device 1 is formed into a trumpet-shaped guide end. Multiple longitudinal rebars conveyed by the longitudinal rebar feeding device 1 enter the guide end of a longitudinal rebar guide pipe 412 respectively and extend from the other end of the longitudinal rebar guide pipe 412 to reach the welding point.

[0072] The lower welding table 42 includes a lower welding table lifting seat 421 and lower welding electrodes 422. Multiple lower welding electrodes 422 are fixed at intervals on the lower welding table lifting seat 421. The multiple lower welding electrodes 422 are arranged linearly laterally and correspond one-to-one with multiple longitudinal rebar guide pipes 412, ensuring that the longitudinal rebars guided by the longitudinal rebar guide pipes 412 pass over the lower welding electrodes 422. Simultaneously, the transverse rebars conveyed by the first transverse rebar feeding device 2 fall onto the lower welding electrodes 422 from above the longitudinal rebars. A longitudinal positioning plate is provided between the multiple lower welding electrodes 422 to longitudinally position the transverse rebars. A positioning cylinder is provided on one side of each lower welding electrode 422, and a positioning block is provided on the other side. The action of the positioning cylinder pushes the transverse rebars conveyed by the first transverse rebar feeding device 2 towards the positioning block, completing the transverse positioning of the rebars. The lower welding table lifting seat 421 can rise and fall under the drive of the lifting mechanism, causing the multiple lower welding electrodes 422 to rise and fall synchronously. The descent of the lower welding platform lifting seat 421, along with the simultaneous rise of the lifting frame 411, drives multiple longitudinal steel bars to rise synchronously, increasing the space between the lower longitudinal steel bars and the lower welding electrode 422. This facilitates the flipping of the transverse steel bar transfer mechanism 33, allowing the transverse steel bars conveyed by the second transverse steel bar feeding device 3 to reach the lower welding electrode 422 from below the longitudinal steel bars, and the transverse steel bars are positioned by the longitudinal positioning plate.

[0073] The upper welding station 43 includes an upper welding station mounting frame 431, an upper electrode lifting structure 432, and an upper welding electrode 433. The upper welding station mounting frame 431 is fixed to the outer casing of the welding device 4. There are multiple upper electrode lifting structures 432 and upper welding electrodes 433, and the number of upper electrode lifting structures 432 and upper welding electrodes 433 is the same as the number of lower welding electrodes 422. The upper electrode lifting structure 432 is usually a lifting cylinder or a lifting hydraulic cylinder. Multiple upper electrode lifting structures 432 are fixed at intervals at the lower part of the upper welding station mounting frame 431, and an upper welding electrode 433 is fixed at the lower part of each upper electrode lifting structure 432. Each upper welding electrode 433 is positioned opposite to a lower welding electrode 422. After the transverse steel bar above or below the longitudinal steel bar is delivered to the lower welding electrode 422, the upper electrode lifting structure 432 is activated, pushing the upper welding electrode 433 down to press on the intersection of the longitudinal and transverse steel bars, and pushing the longitudinal and transverse steel bars into contact with the lower welding electrode 422. Welding current is passed between the upper welding electrode 433 and the lower welding electrode 422, and a transverse steel bar is welded to multiple longitudinal steel bars at the same time.

[0074] After one transverse rebar is welded, the longitudinal rebar feeding device 1 pushes multiple longitudinal rebars forward a set distance, and the first transverse rebar feeding device 2 or the second transverse rebar feeding device 3 conveys the next transverse rebar, continuing the welding of the next transverse rebar. When the longitudinal rebar feeding mechanism 13 in the longitudinal rebar feeding device 1 moves close to the end of the longitudinal rebar feeding seat 11 and it is difficult to further advance the longitudinal rebar, the longitudinal rebar feeding mechanism 13 returns to its original position, and the next set of longitudinal rebars is conveyed. At the same time, the mesh moving output mechanism 44 operates to convey the rebar mesh with the welded passport section completed, so that the rebar mesh with one transverse rebar welded moves longitudinally a set distance, and then the next transverse rebar is welded, until all transverse rebars on the rebar mesh are welded, and then the rebar mesh is conveyed and output to the designated position.

[0075] As one specific embodiment of the steel mesh welding machine of this application, such as Figure 9As shown, the mesh moving output mechanism 44 includes a mesh output frame 441, an output moving seat 442, and an output mesh clamp 443. The mesh output frame 441 is located on the side opposite to the longitudinal rebar feeding device 1, where the lower welding platform 42 and the upper welding platform 43 are located. The welded portions of the longitudinal and transverse rebars are pushed onto the mesh output frame 441 and move longitudinally away from the lower welding platform 42. The output moving seat 442 is mounted on the mesh output frame 441 and is located at the lower part of the mesh output frame 441. Typically, a longitudinally extending slide rail is provided on the mesh output frame 441, and a slider that cooperates with the slide rail is provided on the output moving seat 442, allowing the output moving seat 442 to move longitudinally on the mesh output frame 441 under the action of the output conveying mechanism. The output mesh clamp 443 is fixed to the output moving seat 442 and extends above the mesh output frame 441. The output mesh clamp 443 can use pneumatic grippers. When the output moving seat 442 moves towards the lower welding table 42, the output mesh clamp 443 can clamp the transverse steel bars of the steel mesh on the mesh output frame 441. After the transverse steel bar is welded, the output moving seat 442 moves longitudinally away from the lower welding table 42, pulling multiple longitudinal steel bars to move longitudinally synchronously a set distance, and then welding the next transverse steel bar on the longitudinal steel bar.

[0076] In a preferred embodiment of the steel mesh welding machine of this application, such as Figure 10 and Figure 11 As shown, the first rebar distributor 15, the second rebar distributor 21, and the third rebar distributor 31 all include a distributor frame 51, a rebar storage trough 52, a rebar output roller 53, a rebar distributing roller 54, and a retaining structure 55. The distributor frame 51 forms the structural frame of the rebar distributor. The rebar storage trough 52 is located on the upper part of the distributor frame 51 and is typically composed of a bottom support plate and a metal bracket fixed to the bottom support plate. The rebar storage trough 52 can store a large number of rebars, enabling the single-strand distributing of a large number of rebars, allowing for automatic rebar distributing over a long period and reducing reliance on manual operation. Rebar length limiting plates 521 are provided on both sides of the rebar storage trough 52. The distance between the two rebar length limiting plates 521 can be adjusted so that the length of the rebar storage trough 52 is slightly larger than the length of the rebar, thereby maintaining the neat arrangement of the rebars within the rebar storage trough 52.

[0077] One end of the metal bracket is bent upwards, and the other end is slightly tilted downwards to form the outlet of the rebar storage trough 52. The rebar output roller 53 is set at the outlet of the rebar storage trough 52. The rebar output roller 53 is rotatably fixed on the distributor frame 51. The rotation of the rebar output roller 53 can guide part of the rebar in the rebar storage trough 52 to between the rebar output roller 53 and the rebar distribution roller 54.

[0078] The rebar dispensing roller 54 is rotatably fixed on the distributor frame 51 near the rebar output roller 53 and is arranged parallel to the rebar output roller 53. Specifically, the rebar dispensing roller 54 includes a dispensing roller shaft 541, a dispensing motor 542, a dispensing guide wheel 543, and a dispensing wheel 544. Both ends of the dispensing roller shaft 541 are rotatably mounted on the distributor frame 51, and one end is connected to the dispensing motor 542. The dispensing motor 542 is fixed to the outside of the distributor frame 51 and is driven by the dispensing roller shaft 541, such as through a reducer. The dispensing guide wheel 543 and the dispensing wheel 544 are fixed at intervals on the dispensing roller shaft 541 and can rotate with the dispensing roller shaft 541. Multiple clamping grooves are provided around the dispensing wheel 544. The size of the clamping grooves is slightly larger than the diameter of the rebar, so that when the dispensing wheel 544 rotates, it can clamp one and only one rebar in the clamping groove.

[0079] A vibrator 56 is installed between the rebar output roller 53 and the rebar distribution roller 54. The vibrating disc on the vibrator 56 can generate vibration, driving the rebar between the rebar output roller 53 and the rebar distribution roller 54 to vibrate, which is beneficial for the dispersion of the rebar and its insertion into the clamping groove around the distribution roller 544. An arc-shaped baffle is installed above the distribution roller 544. The gap between the arc-shaped baffle and the edge of the distribution roller 544 is set to allow only the rebar inserted into the clamping groove to pass through, and to prevent the rebar in the clamping groove from sliding out. The rotation amplitude of the distribution roller 544 is controlled so that each rotation of the distribution roller 544 causes only one rebar to slide out from the end of the arc-shaped baffle and slide out along the rebar guide rod.

[0080] The material blocking structure 55 is installed on the rebar guide rod and can block the rebar output from the rebar distribution roller 54, so that the rebar is temporarily stored on the rebar guide rod. The material blocking structure 55 is equipped with a rebar detection element. When the rebar detection element detects that there is a rebar temporarily stored on the material blocking structure 55, it controls the distribution roller 544 to stop rotating, ensuring that only one rebar is temporarily stored on the material blocking structure 55.

[0081] The material-stopping structure 55 includes a material-stopping shaft 551, a material-stopping motor 552, and material-stopping bars 553. The material-stopping shaft 551 is rotatably mounted on the distributor frame 51. The material-stopping motor 552 is fixed on the distributor frame 51 and driven by the material-stopping shaft 551. Multiple material-stopping bars 553 are fixed at intervals on the material-stopping shaft 551. Initially, the material-stopping bars 553 are positioned in a state of intersecting with the rebar guide rod, preventing the rebar from sliding along the rebar guide rod. When the material-stopping motor 552 is working, it can drive the material-stopping shaft 551 to rotate, causing the material-stopping bars 553 to contact the intersection with the rebar guide rod, conveying the temporarily stored rebar out, and then quickly returning to the initial state, forming a rapid, single-bar distribution of rebars.

[0082] As one specific embodiment of the steel mesh welding machine of this application, such as Figure 10 and Figure 11 As shown, the rebar output roller 53 includes an output roller shaft 531, an output motor 532, an output guide wheel 533, and a magnetic output wheel 534. The output roller shaft 531 is rotatably mounted on the distributor frame 51, and the output motor 532 is fixed to the outside of the distributor frame 51 and is drivenly connected to the output roller shaft 531.

[0083] Output guide wheels 533 are fixed at intervals at the outlet of the rebar storage trough 52, and output roller shaft 531 passes through the middle part of the output guide wheels 533. Magnetic output wheels 534 are fixed on the output roller shaft 531 and located between the output guide wheels 533. Magnetic elements are spaced around the periphery of the magnetic output wheels 534. When the output roller shaft 531 rotates under the drive of the output motor 532, the magnetic output wheels 534 rotate synchronously with the output roller shaft 531. The magnetic elements around the magnetic output wheels 534 can attract the rebar, causing a small number of rebars to tumble over the top of the output guide wheels 533 and enter the area between the rebar output roller 53 and the rebar distribution roller 54. The magnetic elements can be electromagnets. When the rebar tumbles over the top of the output guide wheels 533, the power supply to the electromagnet is cut off, causing the rebar to leave the magnetic element; alternatively, the rebar can be blocked by the rebar distribution roller 54, the vibrator 56, or a metal bracket, causing the rebar to leave the magnetic element and remain in the area between the rebar output roller 53 and the rebar distribution roller 54.

[0084] One embodiment of the steel mesh production line of this application is as follows: Figure 12 and Figure 13 As shown, the device includes a slicing device 6 and a steel mesh welding machine according to any embodiment of this application. The slicing device 6 is located on the side of the welding device 4 opposite to the longitudinal steel bar feeding device, that is, on the discharge side of the welding device 4.

[0085] The slicing device 6 includes a wire mesh feeding mechanism 61 and a cutting mechanism 62. The wire mesh feeding mechanism 61 extends over the cutting mechanism 62 from above, thereby enabling the feeding of the steel mesh to both sides of the cutting mechanism 62. The cutting mechanism 62 can use an existing steel bar cutter with a travel width, capable of simultaneously cutting multiple longitudinal steel bars on the steel mesh.

[0086] The wire mesh feeding mechanism 61 includes a feeding transfer frame 611, a movable base 612, a lifting column 613, a gripper frame 614, and grippers 615. The feeding transfer frame 611 is positioned between the welding device 4 and the cutting mechanism 62, and spans over the cutting mechanism 62. A longitudinally extending base slide rail 616 is provided at the top of the feeding transfer frame 611. The movable base 612 is mounted on the base slide rail 616 and can move along the base slide rail in the feeding / discharging direction of the cutting mechanism 62. The lifting column 613 is mounted on the movable base 612 and can rise and fall correspondingly to the movable base 612 under the action of a drive motor. The gripper frame 614 is fixed to the lower end of the lifting column 613, and multiple grippers 615 are fixed on the gripper frame 614, with the grippers 615 spaced apart at the lower end of the gripper frame 614. The grippers 615 are typically pneumatic grippers, with their openings facing downwards.

[0087] After the movable base 612 moves above the welding device 4, the lifting column 613 descends, lowering the gripper 615 to a position opposite to the reinforcing bars on the welded steel mesh on the welding device 4. The gripper 615 is then controlled to clamp the reinforcing bars on the steel mesh. Through the movement of the movable base 612 and the lifting column 613, the steel mesh is moved to a set position in the cutting mechanism 62, where it is cut from the desired location. Further movement of the movable base 612 and the lifting column 613 allows for recutting at a designated location on the steel mesh, and the remaining cut steel mesh is then conveyed from the upper part of the cutting mechanism 62 to its discharge side for centralized processing.
