Reinforcing bar containing grooves 7621 are provided on the circumferential surfaces of the auxiliary turntable 763 and the driving turntable 762. The horizontal bars sliding off the third support bar 756 enter the reinforcing bar containing grooves 7621, and each reinforcing bar containing groove 7621 can only accommodate one horizontal bar.

[0056] A limiting plate 764 is arranged above the driving turntable 762. The top of the limiting plate 764 is fixed to the bottom of the third mounting plate 743. The bottom of the limiting plate 764 is arc-shaped and corresponds to the driving turntable 762. A second limiting rod 765 is fixed to the side of the first limiting rod 757 away from the fixing plate 752. The second limiting rod 765 is arranged vertically downward. A third limiting rod 766 is fixed to the side of the third support bar 756 close to the third rotating shaft 761. The horizontal bar falls between the third limiting rod 766 and the second limiting rod 765.

[0057] A blanking rod 767 is arranged on one side of the third limiting rod 766. The blanking rod 767 is opposite to the second limiting rod 765. The blanking rod 767 is rotatably connected to the third limiting rod 766. A blanking air cylinder 768 for driving the blanking rod 767 to rotate is hinged on the side wall of the fifth support rod 754. When the horizontal bar falls off from the reinforcing bar containing groove 7621, it falls between the blanking rod 767 and the second limiting rod 765, and the blanking rod 767 plays a role in supporting the horizontal bar. When the horizontal bar needs to fall, the blanking air cylinder 768 is started, and the blanking rod 767 rotates, so that the horizontal bar falls into the placing rack 3. As the first driving assembly 73 drives the two second mounting plates 72 to move, the horizontal bar placing assembly 76 evenly places the horizontal bars at the corresponding positions of the placing rack 3.

[0058] A positioning assembly 77 for positioning the horizontal bar is arranged on the fifth support rod 754. The positioning assembly 77 includes positioning air cylinders 771 and second positioning plates 772. There are two positioning air cylinders 771 and two second positioning plates 772. One positioning air cylinder 771 corresponds to one second positioning plate 772. The second positioning plate 772 is fixed on the piston rod of the positioning air cylinder 771. The horizontal bar is located between the two second positioning plates 772. The two positioning air cylinders 771 act together to push the horizontal bar so that the horizontal bar is located in the middle position between the two second positioning plates 772. The horizontal bar enters the driving turntable 762 from the middle position between the second positioning plates 772 and just falls to the corresponding position of the placing rack 3 from the driving turntable 762.

[0059] When the horizontal bar feeding mechanism 7 places the horizontal bars on the placement rack 3, part of the horizontal bars on the second support bar 745 are attracted by the magnetic attraction plate 753. Driven by the second rotating shaft 751, the magnetic attraction plate 753 drives the horizontal bars to rotate. When the two ends of the horizontal bars rest on the third support bar 756, the horizontal bars are separated from the magnetic attraction plate 753. Then the horizontal bars slide down along the third support bar 756. When the horizontal bars close to the driving turntable 762 come into contact with the driving turntable 762 and the auxiliary turntable 763, they enter the next reinforcing bar storage groove 7621. Then, under the action of the driving turntable 762 and the auxiliary turntable 763, the horizontal bars are lifted one by one by the driving turntable 762 and the auxiliary turntable 763. After the horizontal bars fall out of the reinforcing bar storage groove 7621, they fall between the blanking rod 767 and the second limiting rod 765. As the horizontal bar feeding mechanism 7 moves, the blanking air cylinder 768 acts, and the horizontal bars fall to the corresponding positions on the placement rack 3. The previous horizontal bar falls from the blanking rod 767, the blanking rod 767 returns to the initial position, and the next horizontal bar falls out of the reinforcing bar storage groove 7621. This action is repeated in sequence until the placement rack 3 is covered with horizontal bars.

[0060] The longitudinal bar feeding mechanism 8 has the same structure as the horizontal bar feeding mechanism 7. The horizontal bar feeding mechanism 7 is arranged horizontally along the first bottom support frame 1, and the longitudinal bar feeding mechanism 8 is arranged longitudinally along the first bottom support frame 1.

[0061] A third traveling mechanism 9 is provided on the second bottom support frame 2, and the third traveling mechanism 9 has the same structure as the second traveling mechanism 5. A third fixing block 91 is fixed on one side of the placement rack 3 away from the second fixing block 522. A third insertion hole is opened on the third fixing block 91, and the piston rod of the third air cylinder 521 of the third traveling mechanism 9 can be inserted into the third insertion hole. After the pet cage mesh is welded, the third traveling mechanism 9 removes the welded pet cage mesh from the bottom of the gantry welder 11, and then the pet cage mesh is taken off the second bottom support frame 2 by a manipulator.

[0062] The implementation principle of a mesh welding feeding device of the present utility model is as follows: When welding the pet cage mesh, both placement racks 3 are located on the second bottom support frame 2; First, the first traveling mechanism 4 drives one of the placement racks 3 to lift and move, so that the placement rack 3 is separated from the first slide rail 21 and moves to directly below the longitudinal bar feeding mechanism 8, and the longitudinal bar feeding mechanism 8 feeds the longitudinal bars to the corresponding positions on the placement rack 3; Then the first traveling assembly 41 drives the placement rack 3 to move towards the horizontal bar feeding mechanism 7. After moving to directly below the horizontal bar feeding mechanism 7, the horizontal bar feeding mechanism 7 feeds the horizontal bars to the corresponding positions on the placement rack 3.

[0063] After that, the first walking mechanism 4 drives the placing rack 3 to be directly below the rectangular frame feeding mechanism 6. At this time, the rectangular frame feeding mechanism 6 has conveyed the mesh rectangular frame to directly above the placing rack 3, and the rectangular frame feeding mechanism 6 feeds the mesh rectangular frame onto the placing rack 3. After that, the first walking mechanism 4 drives the placing rack 3 back to be below the horizontal rib feeding mechanism 7, and the connecting lifting assembly 42 moves the placing rack 3 downward to make the placing rack 3 return to the first slide rail 21. After that, the first walking mechanism 4 is connected to another placing rack 3 and drives the other placing rack 3 to repeat the above process.

[0064] After placing the longitudinal ribs, horizontal ribs and mesh rectangular frame on the placing rack 3, the second walking mechanism 5 drives the placing rack 3 to move towards the direction of the gantry welder 11, and the gantry welder 11 welds the mesh.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
