The generated suction force will cause the filter plate to slide slightly in the inner cavity of the filter box through the first spring.

When there is a lot of welding slag adsorbed on the filter plate and the welding slag blocks the mesh of the filter plate, the ventilation of the mesh of the filter plate is poor, and the suction force generated by the air suction machine is greater than the tensile force of the first spring, the filter plate is driven to slide downward in the filter box by the continuous suction force of the air suction machine.

Then, when the connecting shaft moves downward, it pulls the arc plate to move by the connecting line. The arc plate slides in the slide groove through the sliding rod, so that the arc plate pushes the welding slag adsorbed on the filter plate into the waste trough for collection, thereby avoiding the welding slag accumulation on the surface of the connecting plate and requiring subsequent cleaning by the staff.

[0017] 4. The present invention provides a cleaning mechanism, and the cleaning block drives the first cleaning plate and the second cleaning plate to clean and scratch the inner wall of the connecting pipe, thereby preventing impurities from being formed on the inner wall of the connecting pipe through the exhaust gas for a long time. At the same time, the suction force of the air intake machine causes the cleaning block to move on the guide rod, so that the knocking rod drives the knocking block to hit the first fixing frame, thereby the impurities scraped off the first cleaning plate and the second cleaning plate are shaken off by the vibration generated by the knocking block and the first fixing frame, thereby preventing the impurities scraped off the first cleaning plate and the second cleaning plate from adhering to the surfaces of the first cleaning plate and the second cleaning plate. At the same time, elastic rods are evenly arranged on the cleaning block, so that when the knocking block collides with the first cleaning plate, the impact force can be reduced to avoid damage to the first cleaning plate and the second cleaning plate due to excessive impact force. At the same time, circular holes are evenly opened on the cleaning block to avoid interference with the exhaust gas absorption work. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 2, using Figure 1-Figure 8 A welding device for thicker pipes of the present invention is described as follows:

[0038] like Figure 1-Figure 8 It is shown that a welding device for thicker pipes of the present invention is based on the first embodiment;

[0039] The air suction component 7 includes an air suction machine 71, and connecting pipes 72 are fixedly connected at both ends of the air suction machine 71. The end of the connecting pipe 72 away from the air suction machine 71 is fixedly connected to the inner wall of the fixing plate 63, the inner wall of the connecting pipe 72 is fixedly connected to the first fixing frame 73, and the end of the inner wall of the connecting pipe 72 away from the air suction machine 71 is fixedly connected to the second fixing plate 63. The inner cavity of the connecting pipe 72 is provided with a guide rod 75, and the end of the guide rod 75 close to the air suction machine 71 is fixedly connected to the outer surface of the second fixing frame 74, and the end of the guide rod 75 away from the second fixing frame 74 is fixedly connected to the outer surface of the first fixing frame 73. The outer surface of the guide rod 75 is sleeved with a second spring 76, and the top of the second spring 76 is fixedly connected to the outer surface of the second fixing frame 74, and the end of the second spring 76 away from the second fixing frame 74 is fixedly connected to the outer surface of the cleaning mechanism 77, and the outer surface of the guide rod 75 is slidably connected to the cleaning mechanism 77;

[0040] The cleaning mechanism 77 includes a cleaning block 771, one end of the cleaning block 771 away from the second spring 76 is fixedly connected to the second cleaning plate 773, and one end of the cleaning block 771 away from the second cleaning plate 773 is fixedly connected to the first cleaning block 771, and the outer surfaces of the first cleaning block 771 and the second cleaning block 771 are evenly provided with through holes 774, and the inner wall of the cleaning block 771 is provided with a clearance hole 775, and the inner wall of the clearance hole 775 contacts the outer surface of the guide rod 75, and the inner wall of the cleaning block 771 is evenly provided with a circular hole 779 on the side away from the clearance hole 775, and the cleaning block 771 is close to the second cleaning plate 773. One end of the cleaning plate 773 is evenly provided with a knocking rod 776, and the number of the knocking rods 776 is four. The four knocking rods 776 are evenly arranged with the clearance hole 775 as the center. The end of the knocking rod 776 away from the second cleaning plate 773 is fixedly connected to the outer surface of the cleaning block 771, and the end of the knocking rod 776 away from the cleaning block is fixedly connected to the knocking block 777. The outer surface of the cleaning block 771 is evenly provided with elastic rods 778, and the two ends of the elastic rods 778 are fixedly connected to the first cleaning plate 772 and the second cleaning plate 773; the exhaust gas generated during welding is sucked into the water tank 1 by the suction force generated by the suction machine 71, and at the same time, The suction force generated by the air suction machine 71 causes the cleaning block 771 to pull the second spring 76 to move on the outer surface of the guide rod 75, so that the cleaning block 771 drives the first cleaning plate 772 and the second cleaning plate 773 to clean and scratch the inner wall of the connecting pipe 72, thereby preventing impurities from being formed on the inner wall of the connecting pipe 72 through the exhaust gas for a long time. At the same time, the suction force of the air suction machine 71 causes the cleaning block 771 to move on the guide rod 75, so that the knocking rod 776 drives the knocking block 777 to impact the first fixing frame 73, thereby generating a vibration between the knocking block 777 and the first fixing frame 73. The impurities scraped off the first cleaning plate 772 and the second cleaning plate 773 are shaken off to prevent the impurities scraped off the first cleaning plate 772 and the second cleaning plate 773 from adhering to the surfaces of the first cleaning plate 772 and the second cleaning plate 773. At the same time, elastic rods 778 are evenly arranged on the cleaning block 771, so that when the knocking block 777 collides with the first cleaning plate 772, the impact force can be reduced to prevent the first cleaning plate 772 and the second cleaning plate 773 from being damaged by excessive impact force. At the same time, circular holes 779 are evenly opened on the cleaning block 771 to avoid interference with the exhaust gas absorption work.

[0041] The specific workflow is as follows:

[0042] During operation, the G115 pipe fitting is placed on the clamping component 3, and the G115 pipe fitting is welded by the welding head 5. At the same time, the exhaust gas and welding slag generated during the welding of the G115 pipe fitting are absorbed by opening the air suction component 7 during the welding operation. The absorbed exhaust gas enters the water tank 1 through the filter component 6 for water filtration and subsequent discharge.

[0043] By placing the G115 pipe fitting on the clamping block 32, placing two G115 pipe fittings on the clamping block 32, and moving the G115 pipe fitting on the clamping block 32, the scraper 35 can scrape the surface of the G115 pipe fitting, thereby scraping off some foreign impurities on the G115 pipe fitting, thereby preventing the impurities attached to the surface of the G115 pipe fitting from interfering with the normal welding work when the G115 pipe fitting is welded. At the same time, after the welding of the surface part of the G115 pipe fitting is completed, the G115 pipe fitting is rotated to contact and rotate with the roller 34, so that the welding angle of the G115 pipe fitting can be adjusted during the welding of the G115 pipe fitting;

[0044] When welding the G115 pipe fitting, the exhaust gas and welding slag generated during the welding of the G115 pipe fitting are sucked off by turning on the air suction machine 71, and the welding slag is adsorbed on the filter plate 62. At the same time, the suction force generated by the air suction machine 71 causes the filter plate 62 to slide slightly in the inner cavity of the filter box through the first spring 64. When there is a lot of welding slag adsorbed on the filter plate 62, the welding slag blocks the mesh of the filter plate 62, and the ventilation of the mesh of the filter plate 62 is poor, the suction force generated by the air suction machine 71 is greater than the tensile force of the first spring 64, and the filter plate 62 is driven to slide downward in the filter box by the continuous suction force of the air suction machine 71. At the same time, when the filter plate 62 moves downward The connecting shaft 67 is driven to move downward. When the connecting shaft 67 moves downward, the connecting line 68 is pulled to move on the rotating wheel 24, so that when the connecting shaft 67 moves downward, the arc plate 65 is pulled to move by the connecting line 68. The arc plate 65 slides in the slide groove 22 through the slide rod 66, so that the arc plate 65 pushes the welding slag adsorbed on the filter plate 62 to the waste tank 23 for collection, thereby avoiding the welding slag from accumulating on the surface of the connecting plate 21 and requiring subsequent cleaning by the staff. At the same time, when the filter plate 62 is blocked and slides in the filter box 61, the anti-blocking mechanism 69 contacts and squeezes the filter plate 62, so that the impurities that cause blockage at the mesh of the filter plate 62 are ejected;

[0045] The filter plate 62 is continuously moved downward, so that the anti-clogging rod 691 drives the ejector pin 695 to eject the welding slag blocked at the mesh of the filter plate 62. At the same time, the filter plate 62 is continuously moved downward, so that the scratch plate 692 scratches the mesh of the filter plate 62, thereby preventing impurities from adhering to the inner wall of the mesh. At the same time, holes 693 are evenly opened on the scratch plate 692, thereby preventing interference with the absorption of exhaust gas.

[0046] The exhaust gas generated during welding is sucked into the water tank 1 by the suction force generated by the suction machine 71. At the same time, the suction force generated by the suction machine 71 causes the cleaning block 771 to pull the second spring 76 to move on the outer surface of the guide rod 75, so that the cleaning block 771 drives the first cleaning plate 772 and the second cleaning plate 773 to clean and scratch the inner wall of the connecting pipe 72, thereby preventing impurities from being formed on the inner wall of the connecting pipe 72 due to the exhaust gas for a long time. At the same time, the suction force of the suction machine 71 causes the cleaning block 771 to move on the guide rod 75, so that the knocking rod 776 drives the knocking block 777 to impact the first fixing frame 73, thereby The vibration generated by the striking block 777 and the first fixing frame 73 shakes off the impurities scraped off the first cleaning plate 772 and the second cleaning plate 773, preventing the impurities scraped off the first cleaning plate 772 and the second cleaning plate 773 from adhering to the surfaces of the first cleaning plate 772 and the second cleaning plate 773. At the same time, elastic rods 778 are evenly arranged on the cleaning block 771, so that when the striking block 777 collides with the first cleaning plate 772, the impact force can be reduced to avoid damage to the first cleaning plate 772 and the second cleaning plate 773 caused by excessive impact force. At the same time, circular holes 779 are evenly opened on the cleaning block 771 to avoid interference with the exhaust gas absorption work.
