The support frame includes a limiting pressure rod, fixed plates fixedly connected to both ends of the limiting pressure rod, and a limiting telescopic rod fixedly connected to one side of the fixed plates. A central groove is provided in the middle of the welding table, which corresponds to the lower part of the main welding machine. An air suction chamber is fixedly installed inside the central groove. An installation box is fixedly installed on one side of the front of the welding table. An induced draft fan is fixedly connected inside the installation box. The input end of the induced draft fan is connected to an air shell. One end of the air shell is threadedly connected to a negative pressure pipe connected to the air suction chamber. An activated carbon filter element is snapped into the inside of the air shell. A control panel is fixedly installed at the bottom of the front of the upright frame.

[0005] Preferably, the main welding machine, electric telescopic rod, limiting telescopic rod, and induced draft fan are all electrically connected to an external power supply via a control panel. The output end of the limiting telescopic rod is fixedly connected to one side of a fixed plate. A fixed plate is fixedly connected to the bottom of the limiting telescopic rod. The fixed plate is fixedly connected to the surface of the welding table. The fixed plate is used to install and fix the limiting mechanism.

[0006] Preferably, a base is fixedly connected to the bottom of the welding table, and a storage box is snapped onto the top of the base. The storage box is used to store the reinforcing bars for welding mesh.

Fixed plates 15 are fixedly connected to both ends of the limiting pressure rod 14 and a limiting telescopic rod 16 is fixedly connected to one side of the fixed plate 15. A middle groove 18 is opened in the middle of the welding table 1. The middle groove 18 corresponds to the lower part of the main welding machine 6. An air suction chamber 20 is fixedly installed inside the middle groove 18. An installation box 11 is fixedly installed on one side of the front of the welding table 1. An exhaust fan 22 is fixedly connected inside the installation box 11. An air shell 23 is connected to the input end of the exhaust fan 22. A negative pressure pipe 21 connected to the air suction chamber 20 is threaded to one end of the air shell 23. An activated carbon filter element 24 is snapped into the inside of the air shell 23. An operation panel 12 is fixedly installed at the bottom of the front of the upright frame 3.

[0018] In this embodiment, several reinforcing bars are positioned by the transverse reinforcing bar positioning groove 8, and their ends are pulled to the position below the spot welding head 7. The spot welding head 7 corresponds to the position of the longitudinal reinforcing bar support frame 9. The longitudinal reinforcing bar support frame 9 is used to place the longitudinal reinforcing bars. After placement, the electric telescopic rod 4 is activated to lower the lifting platform 5 and the main welding machine 6. There are several main welding machines 6. The spot welding head 7 corresponds to the connection point of the transverse and longitudinal reinforcing bars. The spot welding head 7 of the main welding machine 6 is used to weld the connection point of the transverse and longitudinal reinforcing bars. When welding, the limiting telescopic rod 16 of the limiting mechanism 10 retracts and pulls down the fixing plate 15 and the limiting pressure rod 14. The limiting pressure rod 14 limits one side of the longitudinal reinforcing bar.

[0019] See Figure 1-4The main welding machine 6, electric telescopic rod 4, limit telescopic rod 16 and induced draft fan 22 are all electrically connected to an external power supply through the control panel 12.

[0020] See Figure 1-4 A partition net 19 is fixedly installed on the top of the middle tank 18. The top of the partition net 19 is on the same plane as the top of the welding table 1. The opening end of the air intake chamber 20 is set vertically upward. The bottom of the blower 22 is fixedly connected to the bottom of the inner wall of the mounting box 11.

The middle tank 18 corresponds to the spot welding head 7. The welding odor generated during welding is quickly absorbed to reduce diffusion. Furthermore, during the absorption process by the induced draft fan 22, it can be purified and adsorbed by the activated carbon filter element 24 inside the air shell 23.

[0022] In practical use, this utility model of a guardrail welding machine with a limiting mechanism involves positioning several reinforcing bars through the horizontal reinforcing bar positioning groove 8, with the ends pulled down to the position below the spot welding head 7. The spot welding head 7 corresponds to the position of the longitudinal reinforcing bar support frame 9, which is used to place the longitudinal reinforcing bars. After placement, the electric telescopic rod 4 is activated to lower the lifting platform 5 and the main welding machine 6. There are several main welding machines 6, and the spot welding heads 7 correspond to the connection points of the horizontal and vertical reinforcing bars. The spot welding heads 7 of the main welding machines 6 are used to weld the connection points of the horizontal and vertical reinforcing bars. During welding, the limiting telescopic rod 16 of the limiting mechanism 10 retracts. The pull-down fixing plate 15 and the limiting pressure rod 14 limit one side of the longitudinal rib to prevent the rib from moving and affecting the welding. In addition, during the welding process, the induced draft fan 22 is started to continuously generate negative pressure. Specifically, negative pressure is generated through the air shell 23, negative pressure pipe 21 and air intake chamber 20 to continuously absorb the air above. The middle tank 18 corresponds to the spot welding head 7. The welding odor generated during welding is quickly absorbed and its diffusion is reduced. Moreover, during the absorption process by the induced draft fan 22, it can be purified and adsorbed by the activated carbon filter element 24 inside the air shell 23, thereby reducing the pollution of the welding odor to the environment and making it more environmentally friendly.
