[0049] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a welding device suitable for the Y-shaped bevel of a gravure printing roller, comprising a support platform 1, a welding platform 2 fixedly connected to the upper surface of the support platform 1, a hydraulic rod 3 fixedly connected inside the support platform 1, a moving block 4 fixedly connected to the output end of the hydraulic rod 3, a rotating shaft 5 fixedly connected inside the moving block 4, a rotating plate 6 rotatably connected to the outer wall of the rotating shaft 5, a rotating shaft 7 rotatably connected inside the rotating plate 6, a clamping block 8 fixedly connected to the outer wall of the rotating shaft 7, a limiting block 9 fixedly connected to the lower surface of the clamping block 8, a slidably connected outer wall of the limiting block 9 inside the welding platform 2, and a positioning component 10 provided on the upper surface of the welding platform 2.

[0050] Specifically, the support platform 1 supports and fixes the welding platform 2, and fixes the hydraulic rod 3. Activating the hydraulic rod 3 moves the moving block 4, which in turn moves the rotating shaft 5. The rotating shaft 5 rotates the rotating plate 6, which in turn moves the rotating shaft 7. The rotating shaft 7 moves the clamping block 8, which in turn moves the limiting block 9 inside the welding platform 2. The welding platform 2 has a groove inside that limits the positioning of the limiting block 9. The clamping block 8 clamps and fixes the gravure printing roller body 1002, preventing it from shifting during welding, which would affect the welding quality and improve welding accuracy.

[0051] Reference Figure 3The positioning component 10 includes a positioning pin 1001. The lower surface of the positioning pin 1001 is fixedly connected to the upper surface of the welding table 2. The outer wall of the positioning pin 1001 is slidably connected to the gravure printing roller body 1002. The outer wall of the gravure printing roller body 1002 is engaged with the outer wall of the clamping block 8.

[0052] Specifically, the upper surface of the welding table 2 is provided with two positioning pins 1001. The positioning pins 1001 are used to limit the gravure printing roller body 1002. The gravure printing roller body 1002 is provided with a limiting groove for limiting the positioning pins 1001.

[0053] Reference Figure 1 and Figure 4 A support frame 11 is fixedly connected to the upper surface of the support platform 1. A motor 12 is fixedly connected to the outer wall of the support frame 11. A threaded rod 13 is fixedly installed at the output end of the motor 12. The outer wall of the threaded rod 13 is rotatably connected to the inside of the support frame 11. A sliding block 14 is threadedly connected to the outer wall of the threaded rod 13. A limit strip 15 is slidably connected inside the sliding block 14. The upper surface of the limit strip 15 is fixedly connected to the inner top wall of the support frame 11. A connecting plate 16 is fixedly connected to the outer wall of the sliding block 14. A motor 17 is fixedly connected inside the connecting plate 16. A lead screw 18 is fixedly installed at the output end of the motor 17. The outer wall of the lead screw 18 is rotatably connected to the inside of the connecting plate 16.

[0054] Specifically, the support platform 1 fixes the support frame 11, and the support frame 11 fixes the motor 12. Starting the motor 12 drives the threaded rod 13 to rotate, which in turn drives the sliding block 14 to slide on the outer wall of the limiting strip 15. The limiting strip 15 limits the sliding block 14, which in turn drives the connecting plate 16 to move. The connecting plate 16 fixes the motor 17, and starting the motor 17 drives the lead screw 18 to rotate inside the connecting plate 16, thus controlling the welding path.

[0055] Reference Figure 5 and Figure 6 The outer wall of the lead screw 18 is threaded with a connecting block 19, and the inner wall of the connecting block 19 is fixedly connected with a sliding shaft 20; the outer wall of the sliding shaft 20 is slidably connected with a rotating rod 21; the outer wall of the motor 12 is fixedly connected with an arc plate 22, and the inner wall of the arc plate 22 is slidably connected with a limit post 23; the outer wall of the limit post 23 is fixedly connected to the outer wall of the connecting plate 16; the outer wall of the rotating rod 21 is fixedly connected with an electric telescopic rod 24, and the output end of the electric telescopic rod 24 is fixedly connected with a welding head 25.

[0056] Specifically, the lead screw 18 can drive the connecting block 19 to move, the connecting block 19 can drive the sliding shaft 20 to move, and the sliding shaft 20 can drive the rotating rod 21 to rotate by sliding inside the rotating rod 21. The rotating rod 21 has a limit groove inside to limit the sliding shaft 20. The rotating rod 21 can drive the arc plate 22 to rotate, and the arc plate 22 can limit the rotating rod 21 by sliding on the outer wall of the limit post 23. The rotating rod 21 can fix the electric telescopic rod 24. By starting the electric telescopic rod 24, the welding head 25 can automatically weld the gravure printing roller body 1002, improving the welding efficiency.

[0057] Working principle: When this welding device is needed, the gravure printing roller body 1002 to be welded is first placed on the upper surface of the welding table 2, and the gravure printing roller body 1002 is placed on the outer wall of the positioning pin 1001 for initial positioning. At this time, the hydraulic rod 3 is activated to drive the moving block 4 to move. While the moving block 4 is moving, the rotating plate 6 can be driven to rotate on the outer wall of the rotating shaft 5 and the rotating shaft 7, thereby driving the limiting block 9 to slide inside the welding table 2. At the same time, the clamping block 8 is driven to clamp and fix the gravure printing roller body 1002, thereby achieving the effect of limiting the gravure printing roller body 1002 and preventing the gravure printing roller body 1002 from shifting during welding, which would affect the welding quality.

[0058] When welding is required on the gravure printing roller body 1002, starting motor 12 drives the threaded rod 13 to rotate inside the support frame 11. Simultaneously, the threaded rod 13 rotates, causing the sliding block 14 to slide on the outer wall of the limiting strip 15, thereby moving the connecting plate 16. At this time, starting motor 17 drives the lead screw 18 to rotate inside the connecting plate 16, thereby moving the connecting block 19. Simultaneously, the sliding shaft 20 slides inside the rotating rod 21, causing the rotating rod 21 to rotate. Simultaneously, the arc plate 22 slides on the outer wall of the limiting post 23, achieving flexible adjustment of the rotation angle of the rotating rod 21. Then, starting the electric telescopic rod 24 drives the welding head 25 to extend and retract, achieving automatic welding of the gravure printing roller body 1002, improving welding efficiency. This device not only limits the gravure printing roller body 1002, preventing displacement during welding, but also automatically welds the gravure printing roller body 1002, improving welding efficiency.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
