[0023] Please see Figure 1-5 This utility model provides an adjustable rebar braiding and welding machine, including a workbench 1, a frame 2 welded to the top of the workbench 1, a first adjustment mechanism 3 provided on the inner side of the frame 2, a feeding mechanism 5 provided inside the workbench 1, a second adjustment mechanism 6 provided on the top of the feeding mechanism 5, and four self-locking casters 7 rotatably connected to the four corners of the bottom of the workbench 1. The number of self-locking casters 7 is four, which facilitate the operator to move the rebar braiding and welding machine.

[0024] like Figure 1 and Figure 3As shown, the first adjustment mechanism 3 includes a first servo motor 8 detachably connected by mounting screws. A bidirectional lead screw 9 is fixedly mounted on the output end of the first servo motor 8 via a coupling. Two adjusting blocks 10 are threadedly connected to the outer wall of the bidirectional lead screw 9. Guide blocks 11 are fixedly connected to the top of the two adjusting blocks 10. A guide rod 12 is slidably connected inside the guide block 11, completely penetrating the guide block 11. A bidirectional hydraulic cylinder 13 is fixedly connected to the bottom of each of the two adjusting blocks 10. Moving blocks 14 are fixedly connected to the two output ends of each bidirectional hydraulic cylinder 13. An electric push rod 17 is fixedly connected to the bottom of the moving block 14. A connecting rod 18 is fixedly connected to the output end of the electric push rod 17. A steel mesh welding head 4 is fixedly connected to the bottom of the connecting rod 18. The steel mesh welding head 4 is used to weld and fix the steel mesh. A guide rail 15 is provided on the bottom outer wall of the adjusting block 10. A slider 16 is slidably connected inside the guide rail 15. The bottom of the slider 16 is fixedly connected to the top of the electric push rod 17. The guide rail 15 and the slider 16 guide the reciprocating motion of the electric push rod 17, making the electric push rod 17 move more stably. There are two bidirectional hydraulic cylinders 13, and four electric push rods 17 and four connecting rods 18.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, the feeding mechanism 5 includes a second servo motor 19 fixedly installed on one side of the workbench 1. A one-way lead screw 20 is fixedly installed at the output end of the second servo motor 19 via a coupling. A rectangular groove and a guide groove 22 are integrally formed inside the workbench 1. The one-way lead screw 20 is installed inside the rectangular groove via bearings. A reciprocating block 21 is threadedly connected to the outer wall of the one-way lead screw 20. Limiting blocks 23 are fixedly connected to both the front and rear sides of the guide groove 22, and the limiting blocks 23 are slidably connected inside the guide groove 22. The reciprocating block 21 is connected to a second adjusting mechanism 6. The second adjusting mechanism 6 includes a feeding plate 24 fixedly connected to the top of the reciprocating block 21. The feed rack 26 has an internal adjustment groove 25 and a through hole 32, which are connected. The feed rack 26 has an internal transverse placement groove 28 and a internal longitudinal placement groove 29, which are integrally formed. There are three transverse placement grooves 28 and multiple longitudinal placement grooves 29. A positioning screw 27 is inserted through the through hole 32. A positioning screw hole matching the positioning screw 27 is formed on the front outer wall of the feed rack 26. A first metal elastic sheet 30 is fixedly connected to the inner wall of the transverse placement groove 28, and a second metal elastic sheet 31 is fixedly connected to the inner wall of the longitudinal placement groove 29. The first metal elastic sheet 30 limits the transverse reinforcing bars, and the second metal elastic sheet 31 limits the longitudinal reinforcing bars, preventing misalignment of the reinforcing mesh during feeding.

[0026] After the second servo motor 19 is powered on, it drives the one-way lead screw 20 to rotate. After the one-way lead screw 20 rotates, it works with the guide groove 22 and the limit block 23 to drive the feeding plate 24 to reciprocate. Then, the feeding plate 24 drives the second adjustment mechanism 6 to move, thereby driving the steel mesh of the determined size to move and feed, so that the steel mesh welding machine can weld the steel mesh.

[0027] The working principle and usage process of this utility model are as follows: First, the dimensions of the steel reinforcement mesh are determined by placing transverse and longitudinal steel bars inside the feeding rack 26 on the feeding plate 24. The spacing between the feeding racks 26 can be changed according to the adjustment grooves 25 at different positions. First, the distance between different transverse steel bars is determined, and then the distance between different longitudinal steel bars is determined by the positional changes of multiple longitudinal placement grooves 29 inside the feeding rack 26, which facilitates the processing of steel reinforcement mesh of different sizes. After the dimensions of the steel reinforcement mesh are determined, the first servo motor 8 can be started. After the first servo motor 8 is started, it drives the bidirectional lead screw 9 to rotate. After the bidirectional lead screw 9 rotates, it cooperates with the guide block. The guiding action of guide rod 11 and guide rod 12 drives the two adjusting blocks 10 to reciprocate relative to each other, thereby causing the position of the two welding head groups to change. The welding head group is composed of two steel mesh welding heads 4. After the position of the welding head group is initially adjusted, the bidirectional hydraulic cylinder 13 is started. The bidirectional hydraulic cylinder 13 drives the corresponding steel mesh welding head 4 to change position, so that the steel mesh welding head 4 corresponds to the steel mesh of the determined size. The intersection of the steel mesh is welded, and multiple transverse steel bars and multiple longitudinal steel bars are welded and fixed together to form a steel mesh.
