There are supporting columns 9, and a fixing plate 7 is provided between the two supporting columns 9 on one side of the top plate 2, and the two ends of the fixing plate 7 are welded and fixed with connecting rings 701 that are sleeved and fixed with the supporting columns 9. The rotating positioning disk 3 is movably engaged with the bottom of the top plate 2. This structure constitutes the supporting structure of the welding bottom sealing equipment body 1 through the top plate 2, the supporting columns 9 and the bottom plate 10. The fixing plate 7 is firmly fixed between the supporting columns 9 through the connecting ring 701, and the installation height of the fixing plate 7 is adjustable. The rotating positioning disk 3 can be rotated and installed under the positioning of the top plate 2, so that the fixed structure on the rotating positioning disk 3 can be rotated, so that it can be rotated when the iron can is sealed, realizing annular welding, the welding positioning seat 6 and the pressure ring 5 are also movably sleeved and matched, and the bottom of the welding positioning seat 6 The bottom of the tank is fixed with a vertically mounted lifting mechanism 11, and a rotating mechanism 12 is rotatably mounted at the lower end of the lifting mechanism 11. A linear moving mechanism 13 is mounted on the upper end of the bottom plate 10, and the linear moving mechanism 13 is movably connected to the bottom of the rotating mechanism 12 through a screw structure. When the pressure ring 5 is lifted and lowered by the lifting and driving hydraulic cylinder 401, this structure can enable the pressure ring 5 to press the bottom seal to the tank body, thereby realizing the pressure edge positioning processing of the bottom seal. The linear moving mechanism 13 fixes the lifting mechanism 11 through the rotating mechanism 12, so that the lifting mechanism 11 can move under the drive of the linear moving mechanism 13, so that the tank body can be conveniently loaded and unloaded. The lifting mechanism 11 lifts and adjusts the welding positioning seat 6 to make the welding positioning seat 6 The seat 6 can position the tank body, and through the cooperation of the welding positioning seat 6 and the bottom seal positioning piece 8, the bottom seal is clamped and stabilized, so as to achieve the stability of the bottom seal and the tank body, so as to ensure the stable positioning of the tank body bottom seal during welding, and the first connecting rod 301 is evenly spaced and connected between the rotary positioning plate 3 and the bottom seal positioning piece 8, and the first connecting rod 301 and the limiting plate 4 are movably arranged to penetrate, so that the pressure ring 5 can be lifted and lowered under the positioning of the bottom seal positioning piece 8, a welding head fixing frame 17 is provided on the side of the bottom seal positioning piece 8, and a welding head 14 is installed on the end of the welding head fixing frame 17 facing the bottom seal positioning piece 8, and a support roller 1701 is installed on the side of the welding head fixing frame 17 close to the bottom seal positioning piece 8, and the support roller 1701 rolls horizontally,When the welding head fixing bracket 17 moves to the bottom sealing positioning member 8, the supporting roller 1701 can support on the side of the tank body, playing a role of stabilizing and positioning the movement of the welding head 14 relative to the tank body, ensuring the stability of the movement of the tank body relative to the welding head 14. And the other end of the welding head fixing bracket 17 is connected with a welding head adjusting mechanism 15. The other end of the welding head adjusting mechanism 15 is fixedly connected with a movable mounting plate 1501 through a bolt. And a second limiting rod 1505 movably penetrates through the movable mounting plate 1501. And the other end of the movable mounting plate 1501 is fixedly screwed with a first limiting rod 1504. The first limiting rod 1504 is movably penetrated and matched with the fixing plate 7. And a first compression spring 1502 is sleeved between the fixing plate 7 and the movable mounting plate 1501 on the first limiting rod 1504. This structure enables the welding head adjusting mechanism 15 to compress the first compression spring 1502 through the movement of the first limiting rod 1504 relative to the fixing plate 7, causing the welding head adjusting mechanism 15 and the welding head 14 to displace. When performing bottom sealing welding on an irregular tank body, the welding head 14 can always fit the tank body to realize the bottom sealing welding treatment of the tank body. One end of the second limiting rod 1505 is fixedly screwed with the welding head fixing bracket 17. And after the second limiting rod 1505 movably penetrates through the fixing plate 7, a connecting plate 16 is also fixedly screwed together. And a second compression spring 1503 is sleeved between the fixing plate 7 and the connecting plate 16 on the second limiting rod 1505. In the working process of the welding head adjusting mechanism 15, this structure enables the welding head adjusting mechanism 15 to drive the welding head fixing bracket 17 to drive the welding head 14 to move. And the second limiting rod 1505 moves along with the welding head fixing bracket 17, playing a role of limiting the movement of the welding head fixing bracket 17. At the same time, the second limiting rod 1505 compresses the second compression spring 1503 through the connecting plate 16 during the movement process, realizing the overall stability of the welding head adjusting mechanism 15 and the welding head 14 and facilitating the quick reset of the welding head 14.,

[0018] Working principle: When using the welding bottom sealing equipment for canning and iron printing, first, the linear moving mechanism 13 moves the lifting mechanism 11 through the rotating mechanism 12, so that the lifting mechanism 11 moves out of the position below the top plate 2, and the can body and the bottom seal are loaded. The can body is placed on the welding positioning seat 6 for positioning, and then the welding positioning seat 6 is moved to the bottom of the bottom seal positioning piece 8. The welding positioning seat 6 is raised by the lifting mechanism 11, and the bottom seal positioning piece 8 and the welding positioning seat 6 are matched to clamp the bottom seal position, and the lifting drive hydraulic cylinder 401 is started to lift the lifting mechanism 401. The lowering driving hydraulic cylinder 401 drives the limit plate 4 to move downward, and the first connecting rod 301 plays the role of movable limiting on the limit plate 4. The limit plate 4 moves the edge pressing ring 5 downward through the second connecting rod 402. The edge pressing ring 5 is connected with the welding positioning seat 6 and the bottom seal positioning member 8, so that the edge pressing ring 5 performs edge pressing on the bottom seal, so that the bottom seal is fastened relative to the tank body. Then the edge pressing ring 5 is reset, and the rotary positioning disk 3 is rotated by the motor under the positioning of the top plate 2. The rotating mechanism 12 makes the lifting mechanism 11 rotate in conjunction with the rotary positioning disk 3, and at the same time the welding head adjustment mechanism 15 starts The welding head fixing frame 17 is moved to push the welding head fixing frame 17, so that the welding head 14 is fitted to the connection part between the tank body and the bottom cover, and welding is performed during the rotation of the tank body. The supporting roller 1701 is supported on the tank body to make the tank body rotate smoothly. At the same time, the second limiting rod 1505 compresses the second compression spring 1503 through the connecting plate 16 as the welding head fixing frame 17 moves to ensure the stability of the welding head adjustment mechanism 15. If the tank body is a special-shaped structure, the welding head 14 is subjected to a reverse thrust, so that the welding head fixing frame 17 compresses the first compression spring 1503 through the welding head adjustment mechanism 15. 1502 is compressed, and the first limiting rod 1504 is movable and limited by the positioning of the fixed plate 7. At the same time, the second limiting rod 1505 is also movable under the limitation of the fixed plate 7. The rebound force of the second compression spring 1503 enables the welding head fixing frame 17 to smoothly avoid the tank body. The movable mounting plate 1501 plays an adjustable installation and positioning role for the welding head adjustment mechanism 15. The connecting ring 701 makes the fixing plate 7 stable between two of the supporting columns 9. The bottom plate 10 plays an overall supporting role for the welding bottom sealing equipment body 1, thereby completing a series of tasks.
