The rotary driving assembly 46 includes a rotary shaft 461 connected to the rotary wheel 45, and a third servo motor 462 for driving the rotary shaft 461 to rotate.

When the weft steel bar sorting mechanism 3 and the single weft steel bar picking mechanism 4 operate, the controller sends a signal to the second servo motor 344 to enable the weft steel bars to start to operate, and simultaneously sends a signal to the third servo motor 462 to enable the weft steel bars to start to operate.

The weft steel bars sliding down through the single weft steel bar poking and feeding mechanism 4 directly fall into the welding mechanism 5 to weld the warp steel bars and the weft steel bars.

As shown in fig. 15-19, the welding mechanism 5 is connected to the single weft bar picking mechanism 4, and includes a connecting bracket 51 located above the frame, a plurality of sliding locking assemblies (which are prior art and not described in detail herein) with sliding and locking functions located on the connecting bracket 51, a welding gun 52 connected to the sliding locking assemblies, a grooved welding base 53 corresponding to the welding gun 52 (the welding base 53 is connected to the frame through the sliding locking assemblies), an internal tapered guide cylinder 54 connected to the welding base 53 for guiding the warp bars, and a magnet 55 for fixing the weft bars. The two adjacent welding guns 52 form a welding loop, which is respectively connected with a positive lead 56 and a negative lead 57, and every six adjacent welding guns 52 are connected with a transformer 58. When gang welding is performed, a first set of welding guns on each transformer 58 spot welds, and then the other sets of welding guns spot weld in turn. When the transformer 58 is connected with more welding guns, the melting condition of each welding point is easy to be inconsistent, and the quality of the mesh sheet is difficult to control, so that the quality of the mesh sheet is ensured by adopting the connection mode. In order to make the spot welding position more accurate, a photoelectric switch 59 is provided on the welding mechanism, which can measure the distance that the warp steel bar moves, and thus control the time and position during welding.

In the use of welder 52, because the reinforcing bar surface is the arc, at welder 52 extrusion welding's in-process, the phenomenon that welder 52 output shaft sideslips very easily takes place, can cause the output shaft to take place the skew like this, reduces welder 52's life, can produce a large amount of heats simultaneously in the welding process, and this also can cause the harm to welder 52, can have the potential safety hazard even. Therefore, the welding gun 52 comprises a fourth cylinder 531, a limiting protection component 532 connected to the fourth cylinder 531 for protecting the output shaft of the fourth cylinder 531, a circulating water cooling component 533 connected to the limiting protection component 532, and a welding head 534 with a groove connected to the circulating water cooling component 533. The limiting protection component 532 comprises a connecting block 5321, a through hole 5322 penetrating through the connecting block 5321 and used for accommodating the motion of the output shaft of the fourth cylinder 531, a moving shaft 5323 connected to the output shaft of the fourth cylinder 531, a limiting through hole 5324 arranged in parallel with the through hole 5322, and a limiting shaft 5325 positioned in the limiting through hole 5324. The circulating water cooling assembly 533 comprises a containing block 5331 with a cylindrical hollow structure inside, a water inlet 5332 and a water outlet 5333 arranged on the containing block 5331, and a water pipe 5334 with one end connected to the water inlet 5332 and the other end extending to the bottom of the cylindrical hollow structure of the containing block 5331. In order to improve the utilization rate of cooling water, as a more preferable scheme, a water inlet tangent to the cylindrical hollow structure is formed in the bottom of the accommodating block 5331, a water outlet is formed in the upper portion of the accommodating block, a water delivery pipe is not adopted, when the cooling water storage device is used, the input cooling water flows along the circumferential direction of the cylindrical hollow structure, certain directivity is achieved, and the utilization rate of the cooling water can be improved.

Because warp reinforcing bar conveying mechanism 2 is when centre gripping warp reinforcing bar, can reserve out a section of warp reinforcing bar at the front end, when this warp reinforcing bar of reserving out is too long, warp reinforcing bar conveying mechanism 2 is at the in-process of transportation, this section of warp reinforcing bar can take place to vibrate and the deformation, can damage the first cylinder 234 in the centre gripping subassembly 23 to a certain extent on the one hand, on the other hand is when deepening into the guide cylinder 54 in welding mechanism 5, cause the warp reinforcing bar to be difficult to accurate male phenomenon easily, therefore, when warp reinforcing bar conveying mechanism 2 centre gripping warp reinforcing bar, the warp reinforcing bar that the front end was reserved should be shorter, in order to guarantee that it can not take place deformation in transportation process. And when the warp reinforcing bar elongation is shorter, probably can not reach the welded position, consequently need centre gripping subassembly 23 and reciprocating drive subassembly 24 to resume the normal position and carry out the secondary transportation, at the in-process that resumes the normal position, because the warp reinforcing bar is not fixed, the displacement takes place easily, consequently need be equipped with a plurality of compressing tightly revolving cylinder 5101 that are used for fixed warp reinforcing bar on welding mechanism 5, and connect in compressing tightly revolving cylinder 5101 output shaft compressing bar 5102, when the warp reinforcing bar carries out the secondary transportation, the controller sends the signal to compressing tightly revolving cylinder 5101 and makes its compress tightly the weft reinforcing bar that has stretched into, when the warp reinforcing bar transports again, the controller sends the signal to compressing tightly revolving cylinder 5101 and makes its normal position resume.

When the welding mechanism 5 operates, the weft steel bars falling off from the single weft steel bar poking and conveying mechanism 4 are fixed on the welding base 53 through the magnet 55, when the photoelectric switch 59 detects that the input quantity of the warp steel bars reaches a preset value, a signal is sent to the controller, the controller sends a signal to the fourth air cylinder to enable the fourth air cylinder to start to operate (the controller controls six welding guns connected with each transformer to perform welding in three batches in sequence), in the welding process, the controller sends a signal to other mechanisms to enable the six welding guns to stop operating, and after the welding is completed, the controller sends a signal to the other mechanisms to enable the six welding guns to continue to operate.
