Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a welding device for a conveyor roller includes a mounting bracket 1.

Two electric spray heads 6 are symmetrically and fixedly embedded on the top of the mounting bracket 1. An infusion pipe 22 is communicated with the bottom of each of the two electric spray heads 6.
[0023] In this embodiment, a rectangular hole 14 is penetrated and opened on one side of the disc 2. An L-shaped sliding plate 15 is fixedly connected to the side of the second pipe clamp 9 close to the disc 2. A same tension spring 16 is fixedly connected between the bottom of the L-shaped sliding plate 15 and the bottom inner wall of the rectangular hole 14.
[0024] In this embodiment, a plurality of extrusion protrusions 11 are annularly and fixedly connected to the inner walls of the second clamping tube 9 and the first clamping tube 7. The materials of the second clamping tube 9 and the first clamping tube 7 are both copper. A roller can be inserted between the first clamping tube 7 and the second clamping tube 9. If the size of the roller is too large, it will squeeze the second clamping tube 9 to rise and adapt. The second clamping tube 9 is always pulled downward by the pulling force of the tension spring 16, so that it can firmly press the roller for fixation. The extrusion protrusions 11 provided on the inner walls of the second clamping tube 9 and the first clamping tube 7 can increase the friction and prevent slipping during clamping. During clamping, the magnetic chuck 21 can adsorb the metal roller to further strengthen the fixation. After the preparation work is completed, the second motor 20 can be started to drive the bidirectional screw 19 to rotate. After the bidirectional screw 19 rotates, it can drive the two moving tubes 18 to approach each other. After the two moving tubes 18 approach each other, they can drive the two clamped rollers to approach and stick together.
[0025] In this embodiment, two connecting plates 4 are symmetrically and fixedly connected to the top of the mounting frame 1. One end of a telescopic rod 3 is fixedly connected to one side of each of the two connecting plates 4 facing each other, and the telescopic end of the telescopic rod 3 is fixedly connected to an arc-shaped plate 12. The two arc-shaped plates 12 are located between the two first clamping tubes 7.
[0026] In this embodiment, a plurality of welding torches 5 and electric spray nozzles 6 are both located between the two first clamping tubes 7. The two welding torches 5 are located on both sides of the two electric spray nozzles 6.
[0027] In this embodiment, two brackets 13 are symmetrically and fixedly connected to the top of the mounting frame 1. The two brackets 13 are located between the two first clamping tubes 7.
[0028] In this embodiment, the second clamping tube 9 and the first clamping tube 7 have the same diameter. A plurality of through holes are respectively formed in the top of the mounting frame 1, and the moving tube 18 passes through the middle through hole. The two welding torches 5 are respectively fixedly connected to the inner walls of the through holes on both sides. Magnetic chucks 21 are fixedly connected to one side of each of the two discs 2 facing each other.
[0029] The working principle of the present utility model is as follows: A roller can be inserted between the first pipe clip 7 and the second pipe clip 9. If the size of the roller is too large, it will squeeze the second pipe clip 9 to rise and adapt. The second pipe clip 9 is always pulled downward by the pulling force of the tension spring 16, so that it can firmly press the roller for fixation. The extrusion protrusions 11 provided on the inner walls of the second pipe clip 9 and the first pipe clip 7 can increase the friction and prevent slipping during clamping. When clamping, the magnetic chuck 21 can adsorb the metal roller to further strengthen the fixation. After the preparation work is completed, the second motor 20 can be started to drive the bidirectional screw 19 to rotate. After the bidirectional screw 19 rotates, it can drive the two moving pipes 18 to approach each other. After the two moving pipes 18 approach each other, they can drive the two clamped rollers to approach each other and stick together. By rotating the two welding torches 5, the welding work can be started at the docking part of the two rollers. At this time, the first motors 17 on both sides can be started to rotate synchronously. The two discs 2 and the clamped rollers will be driven to rotate synchronously in the same direction. Then, the welding torches 5 on both sides can be started to weld the two rotating rollers. Because the two rollers will rotate, the welding can be carried out for one week at the two welding joints, and then the welding work is completed. Affected by the heat during the welding of the rollers, the second pipe clip 9 and the first pipe clip 7 will be heated up. The temperature of the second pipe clip 9 and the first pipe clip 7 will be conducted to the heat conduction pipe 10 for heat dissipation, so as to cool the roller by using the heat conduction method. The infusion pipe 22 can be connected to a coolant to convey the coolant to the electric spray head 6. The electric spray head 6 can spray the coolant to cool the welding part of the rotating roller. Pulling out the telescopic rod 3 can drive the arc-shaped plate 12 to stick to the outer wall of the welding part of the roller, so as to scrape the impurities on the outer wall of the welding part of the roller.
