Furthermore, the welding mechanism 40 further includes a spring sheet, one end of which is fixed on the longitudinal rib guide frame 30, and the other end of which extends in the direction of the longitudinal rib guide groove. The spring sheet can press the longitudinal rib 100 into the longitudinal rib guide groove under the action of elastic force.

The mesh-pulling cylinder 71 can drive the mesh-pulling beam 72 to move along the second direction, thereby driving the mesh-pulling hook 73 to move along the second direction. When the mesh-pulling cylinder 71 is extended, the mesh-pulling hook 73 is located next to the lower electrode 45, and the main part 201 of the transverse reinforcement 200 to be welded can be positioned. When the mesh-pulling cylinder 71 is retracted, the mesh-pulling hook 73 can move with the welded mesh toward the mesh connecting mechanism 80.

[0064] By controlling the retraction stroke of the net-pulling cylinder 71, the distance that the mesh moves toward the net-connecting mechanism 80 can be controlled, thereby controlling the position where the next transverse rib 200 to be welded is placed on the longitudinal rib 100. Since the stroke of the cylinder is generally fixed, in this embodiment, the net-pulling mechanism 70 also includes a limit column 75 and a buffer 76.

[0071] The position of the longitudinal rib guide frame 30 on the guide rail is adjusted according to the spacing requirements of the longitudinal ribs 100, and the longitudinal ribs 100 placed on the longitudinal rib material holder 20 are manually threaded into the longitudinal rib guide groove, and the front end of the longitudinal rib 100 reaches the position between the upper electrode 44 and the lower electrode 45. After the longitudinal rib 100 is inserted into place, the spring sheet fixes the longitudinal rib 100;

[0072] Drive the net-pulling cylinder 71 to be in an extended state, so that the net-pulling hook 73 is located next to the lower electrode 45, and replace the limit column 75 of a suitable length according to the spacing requirement of the transverse ribs 200, and adjust the spacing between the two net-connecting side frames 81 in the net-connecting mechanism 80 according to the length of the transverse ribs 200;

[0073] Place the transverse ribs 200 placed on the transverse rib material holder 50 on the longitudinal ribs 100. For the straight transverse ribs 200, directly place the transverse ribs 200 on the longitudinal ribs 100 along the net hook 73. For the special-shaped transverse ribs 200, first place the main part 201 on the longitudinal ribs 100 along the net hook 73, and then place the special-shaped part 202 on the positioning plate 61 of the special-shaped transverse rib positioning mechanism 60, and fix it by the positioning magnet;

[0074] The welding cylinder 43 is driven to extend, so that the upper electrode 44 and the lower electrode 45 are closed to weld the longitudinal ribs 100 and the transverse ribs 200. After the welding of one transverse rib 200 is completed, the welding cylinder 43 is retracted to open the upper electrode 44 and the lower electrode 45. Then, the mesh-pulling cylinder 71 is retracted, and the mesh-pulling hook 73 moves with the welded mesh, and delivers the welded mesh to the mesh-connecting mechanism 80.

[0075] The net-pulling cylinder 71 extends again, so that the net-pulling hook 73 reaches the lower electrode 45, and positions the next transverse rib 200. Then, the next transverse rib 200 is placed on the longitudinal rib 100, and the next mesh is welded. The whole mesh is welded in this way, and a standard mesh can be welded (see Figure 6 ), U-net (see Figure 7 ), L-type network (see Figure 8 ) and other specifications of mesh.

[0076] Preferably, a foot switch 90 is provided on the frame 10, and the foot switch 90 controls the overall welding action.
