[0019] Embodiment

[0020] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an automatic welding device for a printing cylinder includes a base 1.

The bottom of the support frame 6 is equipped with a welding head 7. The output end of the lifting mechanism is equipped with an adjusting frame 8. The end of the adjusting frame 8 is equipped with a welding gun 9. The lifting mechanism includes a lifting frame 2 fixedly connected to the top of the base 1. A lifting motor 3 is installed at the top of the lifting frame 2. The output end of the lifting motor 3 is fixedly connected with a lifting screw rod 4. An outer surface of the lifting screw rod 4 is threadedly connected with a lifting block 5. The lifting block 5 is slidably connected with the lifting frame 2. The support frame 6 is installed at the end of the lifting block 5. The adjusting frame 8 is installed at the end of the lifting block 5. A turning mechanism is installed inside the base 1.

The top of the base 1 is threadedly connected with an adjusting screw rod 16. A positioning pad 17 is installed at the bottom of the adjusting screw rod 16.

[0021] When in use, the turning mechanism is in a horizontal state. Place the printing cylinder in the turning mechanism and start the pressing mechanism to clamp the printing cylinder. Then, start the turning mechanism to turn one end face of the printing cylinder upwards. At this time, start the lifting motor 3 to make the lifting screw rod 4 rotate, and then make the lifting block 5 move downward in the lifting frame 2 until the welding head 7 and the welding gun 9 reach the welding end face of the printing cylinder. Then, start the welding head 7 and the welding gun 9 to weld the end face of the printing cylinder. After one end face of the printing cylinder is welded, make the lifting block 5 move upward a certain distance. Then, start the turning mechanism to turn the printing cylinder by 180 degrees so that the other end face of the printing cylinder is in the upward state. Then, make the lifting block 5 descend, and the welding head 7 and the welding gun 9 reach the welding end face of the printing cylinder to weld the other end face of the printing cylinder. After welding is completed, start the lifting motor 3 to make the lifting block 5 move upward to the initial state. Then, start the turning mechanism to make the printing cylinder in a horizontal state. At this time, start the pressing mechanism to make the pressing mechanism unable to clamp the printing cylinder, and then the welded printing cylinder can be removed.

[0022] The welding of two end faces of the printing cylinder is realized, which reduces the burden on personnel. And this device can weld printing cylinders of different lengths, with a wide range of applications.

[0023] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the steering mechanism includes a servo motor 10 fixedly connected inside the base 1. The output end of the servo motor 10 is fixedly connected with a rotating shaft 11. The outer wall of the rotating shaft 11 is fixedly connected with a transmission gear 12. The outer surface of the transmission gear 12 meshes with a steering gear 13. A rotating cylinder 14 is rotatably connected inside the base 1. The steering gear 13 is fixedly connected to the outer wall of the rotating cylinder 14. The end of the rotating cylinder 14 is fixedly connected with a storage bin 15. A rolling mechanism is installed inside the storage bin 15. The inner wall of the storage bin 15 is fixedly connected with a guiding plate 18. The positioning pad 17 is adapted to the storage bin 15. The rolling mechanism includes a driving motor 19 fixedly connected to the inner wall of the storage bin 15. The output end of the driving motor 19 is fixedly connected with a rotating rod 20. The outer wall of the rotating rod 20 is fixedly connected with a driving gear 21. Two connecting shafts 23 are rotatably connected through the side wall of the storage bin 15. The ends of the two connecting shafts 23 are both fixedly connected with rolling wheels 24. Rotating gears 22 are fixedly connected to the outer walls of the two connecting shafts 23 located inside the storage bin 15. The rotating gears 22 mesh with the driving gear 21. The end of the rotating rod 20 is rotatably connected to the inner wall of the storage bin 15. The pressing mechanism includes a cylinder 25 fixedly connected inside the rotating cylinder 14. The output end of the cylinder 25 is fixedly connected with a guiding block 26. A placement groove 27 is formed on the side of the guiding block 26 away from the cylinder 25. A rotating wheel 28 is installed on the guiding block 26. The guiding block 26 is slidably connected to the storage bin 15 and the guiding plate 18. The guiding block 26 is adapted to the guiding plate 18.

[0024] When placing the plate cylinder in the storage bin 15, the plate cylinder is positioned above the guiding plate 18. Then, start the air cylinder 25 so that the air cylinder 25 pushes the guiding block 26 to move leftward, pushing the plate cylinder to enter between the rolling wheels 24, into the placement groove 27, and between the rotating wheels 28 under the action of the guiding plate 18 and the guiding block 26 until the plate cylinder is clamped by the rolling wheels 24 and the rotating wheels 28. Then, start the servo motor 10 so that the rotating shaft 11 drives the transmission gear 12 to rotate, and then drives the rotating cylinder 14 to rotate through the steering gear 13, causing the storage bin 15 to rotate by ninety degrees, and thus causing the plate cylinder to rotate by ninety degrees. When the storage bin 15 rotates by ninety degrees, the positioning pad 17 will contact the storage bin 15. If the storage bin 15 is not in a vertical state, the position of the positioning pad 17 can be adjusted by rotating the adjusting screw 16, so as to achieve that the storage bin 15 can reach a vertical state when rotating. After the storage bin 15 reaches a vertical state, the welding head 7 and the welding gun 9 can reach the end face of the plate cylinder through the lifting mechanism to weld the plate cylinder. During the welding process, start the driving motor 19 so that the rotating rod 20 drives the connecting shaft 23 to rotate through the driving gear 21 and the rotating gear 22, and then the rolling wheels 24 cooperate with the rotating wheels 28 to drive the plate cylinder to rotate, enabling the welding head 7 and the welding gun 9 to comprehensively weld the end face of the plate cylinder. After the welding of this end face is completed, turn off the driving motor 19, start the servo motor 10 to make the storage bin 15 rotate reversely by one hundred and eighty degrees, and then start the driving motor 19 again to make the plate cylinder rotate, so that the welding head 7 and the welding gun 9 can comprehensively weld the end face of the plate cylinder;

[0025] The steering operation of the plate cylinder is realized, which reduces the burden on personnel, improves the welding efficiency, well protects the operators, and is convenient to use.

[0026] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
