The post-weld feeding bin (1002) is arranged on the post-weld feeding frame (1001), and the primary feeding mechanism (1008) and the secondary feeding mechanism (1011) are arranged on the post-weld feeding frame (1001). 003) are sequentially arranged above the post-weld feeding bin (1002), the post-weld feeding cylinder (1004) is connected to the secondary feeding mechanism (1003); the post-weld feeding chute (1010) is arranged beside the secondary feeding mechanism (1003), and is connected to the post-weld feeding guide mechanism (1005) through the post-weld feeding conveyor belt (1009) and the post-weld feeding motor (1011), the clamp (1006) is arranged below the smooth bending structure of the post-weld feeding guide mechanism (1005), and the blocking mechanism (1007) is arranged below the clamp (1006); During the post-welding feeding process, the welded steel pipe is stored in the post-welding feeding bin (1002), and the steel pipe is lifted from the post-welding feeding bin (1002) by the primary feeding mechanism (1008); then the post-welding feeding cylinder (1004) drives the secondary feeding mechanism (1003) to receive the steel pipe from the primary feeding mechanism (1008) and to rise; then, the steel pipe slides from the post-welding feeding chute (1010) to the post-welding feeding conveyor belt (1009), and is conveyed toward the post-welding feeding guide mechanism (1005) by the transmission of the post-welding feeding motor (1011); when the steel pipe enters the post-welding feeding guide mechanism (1005), it will pass through the post-welding feeding guide mechanism (100 5) is flipped from horizontal to vertical; the steel pipe enters the post-welding feeding guide mechanism (1005) and slides, and when the sensor detects the steel pipe, the clamp (1006) clamps the steel pipe; the steel pipe under the clamp (1006) enters the product transport component (8), and the steel pipe above the clamp (1006) cannot continue to fall due to being clamped; after the steel pipe under the clamp (1006) completely enters the product transport component (8), the material blocking mechanism (1007) extends to block the feeding port, and then the clamp (1006) opens to allow the steel pipe to fall onto the material blocking mechanism (1007), and finally, the clamp (1006) closes again to clamp the steel pipe, and this process is repeated to achieve the feeding of steel pipes one by one.

9. The steel pipe welding spraying equipment according to claim 8, characterized in that: The welding assembly (11) comprises a rotating mechanism (1101), a welding material pushing mechanism (1102), a welding gun mechanism (1103), a cap pressing mechanism (1104), a cap removing mechanism (1105) and a material unloading mechanism (1106); the rotating mechanism (1101) and the welding material pushing mechanism (1102) are arranged on one side of the welding assembly (11), the cap removing mechanism (1105) and the cap pressing mechanism (1104) are arranged on the other side of the welding assembly (11), the cap pressing mechanism (1104) is arranged on the side of the welding gun mechanism (1103), and the material unloading mechanism (1106) is arranged between the rotating mechanism (1101) and the cap pressing mechanism (1104); during the welding process, the chamfered second steel is clamped by the rotating mechanism (1101) The second steel pipe (804) is provided with a second cap-taking mechanism (1105), and the iron cap is grasped by the cap-removing mechanism (1105), and the iron cap is pressed into the second steel pipe (804) by the cap-pressing mechanism (1104); subsequently, the welding gun mechanism (1103) welds the contact point between the second steel pipe (804) and the iron cap, and at the same time, the rotating mechanism (1101) clamps the second steel pipe (804) and rotates it; after welding is completed, the cap-pressing mechanism (1104) releases the pressure on the iron cap, and at the same time, the rotating mechanism (1101) releases the clamping of the second steel pipe (804); finally, the welding lifting mechanism (1102) lifts up the welded steel pipe, and the unloading mechanism (1106) clamps the welded steel pipe and places it in the post-welding loading bin (1002) of the post-welding loading assembly (10).
