in the process that the contact rod 22 is pressed downwards, the rotating rod 21 drives the first gear 24 to rotate, the rotating first gear 24 drives the toothed plate 32 to drive the gas filling plate 29 to move upwards, the gas in the gas filling cavity 27 is extruded into the gas collecting cavity 10 and stored, and the gas entering the gas collecting cavity 10 drives the piston plate 11 to move leftwards to extrude the first elastic block 12;

when the telescopic rod 8 drives the extrusion plate 9 to extend into the groove 6 to extrude the winding rib 1, along with the movement of the extrusion plate 9, at this time, the air baffle plate 34 is not extruded by the extrusion plate 9 any more, at this time, the air baffle plate 34 moves to the left under the action of the fifth elastic block 35, at this time, one end of the air baffle plate 34 extends into the extrusion groove 7, and the other end of the air baffle plate exits from the air passage 13, the air baffle plate 34 drives the magnetic block 37 to move to the left in the process of moving to the left, at this time, the magnetic block 37 moves to the right above the magnetic rod 36, the magnetic rod 36 extends into the air collection cavity 10 under the action of the repulsive force of the magnetic block 37, because the air baffle plate 34 exits from the air passage 13, at this time, the piston plate 11 discharges the air in the air collection cavity 10 into the groove 6 through the air passage 13 to clean the welding point reaching the bottom of the groove 6 by blowing, and the piston plate 11 moves to the right for a distance and then is blocked by the magnetic rod 36;

meanwhile, the extrusion plate 9 continuously extends into the groove 6, at the moment, the driving rod 38 continuously moves upwards to extrude the air baffle plate 34, the air baffle plate 34 moves right to block the air channel 13 again, at the same time, the magnetic rod 36 loses the repulsive force of the magnetic block 37, and at the moment, the magnetic rod 36 exits from the air collecting cavity 10 under the action of the elastic rod 361;

when the extrusion plate 9 and the winding rib 1 are extruded, the baffle 17 is extruded around the rib 1 at the moment, so that the baffle 17 moves downwards, the air outlet 16 leaks, the piston plate 11 moves rightwards continuously at the moment, residual gas in the gas collection cavity 10 is extruded out through the air outlet 16, and the butt welding point at a short distance is blown and cleaned;

in the process of blowing up and cleaning the welding point, blown-up dust and impurities are stuck by the sticky plate 40 on one side, meanwhile, in the process of moving up and extruding the winding rib 1 on the extrusion plate 9, the extrusion plate 9 pulls the moving plate 43 to move through the pull rope, under the action of a plurality of groups of gear teeth 46 and second torsion springs 50 which are arranged on the moving plate 43 at intervals, the second gear 47 and the vertical rod 48 firstly rotate to enable the traction rope 49 to be wound on the vertical rod 48, the sticky plate 40 is pulled to move and extrude the sixth elastic block 41 on one side, then when the part without the gear teeth 46 on the moving plate 43 moves to the second gear 47, under the action of the second torsion springs 50 and the sixth elastic block 41, the vertical rod 48 and the second gear 47 do reset rotation, at the moment, the sticky plate 40 suddenly loses tension, swings under the action of the sixth elastic block 41, blown-up dust and impurities are better stuck, and other welding points are prevented from being influenced.
