[0028] The working principle of a steel pipe automatic feeding mechanism 2 is as follows: 1); The staff adjusts the quantity and the spacing installed on the connecting plate 2603 of the fixed plates 2604 and the loading plates 2605 according to the loading sequence of the steel pipes and the dimensions of the steel pipes. Transport the steel pipes to be processed onto the loading table 1, start the output motor 24, drive the driving sprocket 2502 to rotate through the output motor 24, drive the driven sprocket 2503 to rotate through the transmission of the transmission chain 2501, and drive the shaft rod 23 to rotate by the driven sprocket 2503. The rotation of the shaft rod 23 drives the first sprocket 2601 to rotate, drives the first chain 2602 engaged with it to move through the first sprocket 2601. At the same time, the second sprocket 2606 and the third sprocket 2607 are synchronously driven to rotate through the first chain 2602. The movement of the first chain 2602 also synchronously drives the connecting plate 2603 installed on its first link to move, drives the fixed plate 2604 to rotate through the connecting plate 2603, and then drives the loading plate 2605 to rotate. The steel pipe is contacted by the loading plate 2605. Since the first chain 2602 is inclined and the loading plate 2605 and the mounting plate are inclined, the loading plate 2605 drives the steel pipe to roll towards its bottom, and then the steel pipe is lapped on the top of the loading plate 2605, realizing the transportation of the steel pipe.

[0029] 2); When the tension of the first chain 2602 needs to be adjusted, hold and rotate the handwheel 3401, and then drive the screw rod 34 to rotate. The screw rod 34 rotates and moves up and down in the threaded hole. The screw rod 34 synchronously drives the adjusting block 35 to displace. The adjusting block 35 drives the positioning rod 36 to move, and then drives the third sprocket 2607 to move, changing the spacing between the third sprocket 2607 and the first sprocket 2601, and then changing the tension of the first chain 2602.
