[0022] Please refer to the attached Figure 1-3 A convenient submerged arc welding robot arm system includes a connecting plate 1 installed at the movable end of the robot arm, a welding gun 2 is installed on the lower surface of the connecting plate 1, two circular holes are opened on the upper surface of the connecting plate 1, and then a discharge pipe 3 for discharging flux such as manganese, titanium, silicon and the like and a first suction pipe 4 for absorbing excess flux such as manganese, titanium, silicon and the like are respectively installed in the two circular holes, an L-shaped plate 5 is installed in the discharge pipe 3 to divide the discharge pipe 3 into two parts, the first suction pipe 4 runs through the discharge pipe 3 and the L-shaped plate 5, and then is connected to a second suction pipe 6 on the side of the annular surface of the discharge pipe 3 away from the first suction pipe 4.

[0023] The discharge pipe 3 is rotatably connected to the first rotating rod 8 on one side inside the L-shaped plate 5, and a plurality of rotating plates 7 arranged in an annular manner and equidistant therefrom are installed on the annular surface of the first rotating rod 8. One end of the first rotating rod 8 extends to the outside of the discharge pipe 3 and is installed with a first sprocket 17. A second rotating rod 15 rotatably connected to the discharge pipe 3 is arranged below the first rotating rod 8. One end of the second rotating rod 15 also extends to the outside of the discharge pipe 3 and is installed with a second sprocket 19, and the first sprocket 17 and the second sprocket 19 are connected by a chain 18. A plurality of rotating plates 14 arranged in an annular manner and equidistant therefrom are installed on the annular surface of the second rotating rod 15, and the plurality of rotating plates 14 are staggered with the plurality of rotating plates 7.

[0024] An intercepting structure consisting of a second rotating rod 15 and a rotating plate is installed in the space formed by the L-shaped plate 5 and the discharge pipe 3 to seal the opening between the L-shaped plate 5 and the discharge pipe 3. At the same time, the rotating structure consisting of the first rotating rod 8 and the rotating plate 7 is used to drive the intercepting structure to rotate, so that the intercepting structure can directly transfer the manganese, titanium, silicon and other fluxes with higher temperatures sucked into the second suction pipe 6 to the discharge pipe 3 again for discharge, thereby saving time and resources spent on transferring the manganese, titanium, silicon and other fluxes, and avoiding heat loss of this part of the manganese, titanium, silicon and other fluxes.

[0025] And after the absorbed manganese, titanium, silicon and other fluxes with higher temperatures are intercepted by the interception net 9, the heat is still discharged through the first suction pipe 4, so that the manganese, titanium, silicon and other fluxes discharged from the discharge pipe 3 through the first suction pipe 4 can be preheated, thereby increasing the initial temperature of this part of the manganese, titanium, silicon and other fluxes.

[0026] A rectangular groove is provided in the vertical portion of the L-shaped plate 5, and an intercepting plate 10 is inserted into the rectangular groove, one end of the intercepting plate 10 is in contact with the rotating plate 14, and an inclined surface is provided on the surface of the intercepting plate 10 in contact with the rotating plate 14, and then a plurality of movable rods 11 are hinged on the lower surface of the end of the intercepting plate 10 away from the rotating plate 14, and one end of the movable rod 11 away from the intercepting plate 10 is sleeved with a pipe sleeve 12, and one end of the pipe sleeve 12 away from the movable rod 11 is hinged to the vertical portion of the L-shaped plate 5, and an elastic member 13 is installed at one end of the movable rod 11 in the pipe sleeve 12, and the elastic member 13 is a spring, and the elastic member 13 is in a normal state, and one end of the elastic member 13 away from the movable rod 11 is installed in the tube body.

[0027] An interception structure consisting of an interception plate 10, a pipe sleeve 12, a movable rod 11 and an elastic member 13 is installed on the L-shaped plate 5. The interception structure is used to intercept the material discharged from the discharge pipe 3, so that the manganese, titanium, silicon and other fluxes with higher temperatures sucked by the second suction pipe 6 can be reused first, thereby reducing the heat loss of the manganese, titanium, silicon and other fluxes.

[0028] Then, an arc plate 16 having the same size as the rotating arc surface of the rotating plate 14 is installed on the side of the discharge pipe 3 facing the rotating plate 14 and the side of the L-shaped plate 5 facing the rotating plate 14. The arc plate 16 is used to seal the rotating plate 14 when it rotates to prevent air from entering the first suction pipe 4 from below the discharge pipe 3.

[0029] An interception net 9 is installed on the inner surface of one end of the first suction pipe 4 that contacts the L-shaped plate 5 , and the interception net 9 is used to intercept flux such as manganese titanium silicon to prevent the flux such as manganese titanium silicon from being sucked away by the first suction pipe 4 .

[0030] The specific operation process of the present invention is as follows: after the first suction pipe 4 generates suction, the air flow generated by the suction drives the rotating structure composed of the first rotating rod 8 and the rotating plate 7 to rotate, and at the same time, the manganese, titanium, silicon and other fluxes in the position after welding are adsorbed and transported to the rotating plate 7 through the second suction pipe 6, and brought to the rotating plate 14 and the interception net 9 as the rotating plate 7 rotates, and are intercepted by the interception net 9. Since the second rotating rod 15 is connected to the first rotating rod 8 by a linkage structure composed of the first sprocket 17, the second sprocket 19 and the chain 18, the first rotating rod 8 and the rotating plate 7 will be driven to rotate by the second rotating rod 15 and the rotating plate 14 after the rotation, so that the manganese, titanium, silicon and other fluxes fall between the two rotating plates 14 and are brought to the side of the rotating plate 14 away from the rotating plate 7. Since the rotating plate 14 is sealed by the arc plate 16, the manganese, titanium, silicon and other fluxes lose the adsorption of the first suction pipe 4 after moving to the side of the rotating plate 14 away from the rotating plate 7, and thus fall from the discharge pipe 3.

[0031] At the same time, the rotating plate 14 contacts the intercepting plate 10 when rotating, and the intercepting plate 10 is pushed by the rotating plate 14 and moves to the side away from the rotating plate 14, thereby blocking the manganese, titanium, silicon and other fluxes normally discharged into the discharge pipe 3, so that the flow of manganese, titanium, silicon and other fluxes normally discharged into the discharge pipe 3 slows down, so that the high-temperature manganese, titanium, silicon and other fluxes intercepted by the rotating plate 14 from between the first suction pipe 4 and the second suction pipe 6 can be reused first, reducing the heat loss of the manganese, titanium, silicon and other fluxes.

[0032] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
