step two: then moving the bundling disc (8) to the position right below the feed hopper (3), enabling the bundling groove (15) to face the outlet (23), feeding steel pipes to be bundled into the discharge box (11) through an opening in the top of the feed hopper (3), starting the dual-drive motor (9) through the PLC (4), driving the rotating rod (12) penetrating into the discharge box (11) to rotate by using the two drive shafts (10) connected with the dual-drive motor (9), so as to assist the steel pipes to fall into the bundling groove (15) from the outlet (23), supporting the steel pipes by the two elastic bundling strips (28) after falling into the bundling groove (15), and stopping feeding the steel pipes from the feed hopper (3) when the number of the steel pipes falling into the bundling groove (15) reaches 10;

step three: two air pumps (25) are started firstly through a PLC (programmable logic controller) (4), the air pumps (25) are utilized to drive pneumatic telescopic rods (26) to extend to drive clamping plates (24) to be close to each other inside a bundling groove (15), so that two ends of steel pipes inside the bundling groove (15) are placed in an aligned mode, after the steel pipes are aligned, two suction pumps (29) are controlled to be closed through the PLC (4), at the moment, suction discs (32) do not adsorb the outer walls of two sides of elastic bundling strips (28), the elastic bundling strips (28) quickly return to the original annular state, the steel pipes are wrapped and bundled quickly, at the moment, the PLC (4) controls a conveying motor (20) to be started, the conveying motor (20) drives a rotating shaft (18) and a conveying gear (19) to rotate, so as to drive a crawler belt (16) to rotate, the bundling discs (8) are moved out from the position under a feeding hopper (3), at the moment, an operator clamps buckles (34) on the elastic bundling strips (28) inside clamping holes, an operator takes a bundle of steel pipes together with two elastic binding strips (28) out of the binding disc (8);

step four: putting new elastic bundling strips (28) in the two overlapping grooves (27), starting the crawler (16) to reset the bundling disc (8) and repeating the first step, the second step and the third step to bundle the next bundle of steel pipes;

the elastic bundling strip (28) is adopted for bundling, and the elastic bundling strip (28) is made of elastic plastic materials or metal materials with memory, so that the traditional steel wire or rope is replaced for bundling, knotting of the steel wire or rope in automatic bundling inside equipment is avoided, and the steel wire or rope does not need to be cut manually;
