A slide groove 9 is provided on the surface of the fixed plate 8, and a cleaning rod 15 is slidably connected to the inner wall of the slide groove 9, and the surface of the cleaning rod 15 is fixedly connected to the rack 13, and a spring 20 is fixedly connected to the inside of the fixed plate 8, and the end of the spring 20 away from the fixed plate 8 is fixedly connected to the rack 13.

[0025] The surface of the support platform 1 is fixedly connected to the support plate 2, the interior of the support plate 2 is provided with a lifting plate 4, the surface of the lifting plate 4 is provided with a welding device 5, the surface of the lifting plate 4 is fixedly connected to the connecting rod 6, the end of the connecting rod 6 away from the lifting plate 4 is fixedly connected to the pushing plate 7, the pushing plate 7 is inclined close to the side of the connecting plate 12, and welding by moving the welding device 5 is an existing known technology, so it will not be explained in detail.

[0026] When the welding device 5 is lowered to weld the object, the lifting plate 4 slides to drive the connecting rod 6 to move, so that the connecting rod 6 drives the push plate 7 to move, so that the inclined surface of the push plate 7 extrudes the connecting plate 12, the connecting plate 12 is forced to drive the rack 13 to move, the rack 13 drives the cleaning rod 15 to move in the sliding groove 9, and the rack 13 slides to extrude the spring 20, the rack 13 drives the gear 19 to rotate, and the gear 19 drives the shielding plate 10 to move, so that the shielding plate 10 slides to cover the welding area. At this time, the object to be welded is placed from one side of the shielding plate 10 into the shielding plate 10, and after welding, the welding device 5 is moved upwards, so that the welding device 5 drives the connecting rod 6 and the push plate 7 to move, so that the push plate 7 no longer abuts against the connecting plate 12. Under the action of the elastic force of the spring 20, the rack 13 is reset to slide, so that the rack 13 drives the rotating rod 18 and the gear 19 to reset and rotate, so that the shielding plate 10 moves away from above the welded object. At the same time, the rack 13 drives the cleaning rod 15 to move, the cleaning rod 15 moves to scrape and clean the welding slag generated during welding, and at the same time, the object to be welded is pushed to one side, which is convenient for workers to take and clean the table top in the later period. Moreover, the cleaning rod 15 is prevented from pushing the object to be welded during welding.

[0029] When the welding slag and dust are pushed by the cleaning rod 15, they will fall into the collecting groove 17 through the groove 16, and due to the inclined surface of the collecting groove 17, the falling welding slag and dust will slide into the recycling box 3 through the inclined surface, and be collected for later cleaning by workers.

[0030] The surface of the shielding plate 10 is embedded with a ball, and the surface of the ball is in contact with the inner wall of the limiting groove 14, so that the friction between the shielding plate 10 and the limiting groove 14 is reduced through the arrangement of the ball, and the shielding plate 10 is facilitated to slide.

[0031] Working principle: When the welding equipment 5 moves down to weld the object, the lifting plate 4 slides to drive the connecting rod 6 to move, and the connecting rod 6 drives the push plate 7 to move, so that the inclined surface of the push plate 7 squeezes the connecting plate 12, and the connecting plate 12 is forced to drive the rack 13 to move, and the rack 13 drives the cleaning rod 15 to move inside the slide 9, and the rack 13 slides to squeeze the spring 20, and the rack 13 moves to drive the gear 19, and the gear 19 drives the rotating rod 18 to rotate. At the same time, the gear 19 drives the shielding plate 10 to move, so that the shielding plate 10 slides to cover the welding area. At this time, the object to be welded is Put it into the shielding plate 10 from one side. When welding is completed, the welding equipment 5 is moved up, so that the welding equipment 5 drives the connecting rod 6 and the push plate 7 to move, so that the push plate 7 no longer conflicts with the connecting plate 12. Under the elastic force of the spring 20, the rack 13 is reset and slid, so that the rack 13 drives the rotating rod 18 and the gear 19 to reset and rotate, so that the shielding plate 10 is moved away from the top of the welding object. At the same time, the rack 13 drives the cleaning rod 15 to move. While the cleaning rod 15 moves to scrape and clean the welding slag generated by welding, it also pokes the welding object and moves the object to one side for the convenience of the staff to take it.
