Description

Technical Field

[0001] This invention relates to the field of tank welding technology, specifically to an automatic welding device for vertical storage tanks. Background Technology

[0002] With the continuous development of my country's economy, the chemical industry is experiencing tremendous growth, with the output and sales of chemical products increasing year by year. Correspondingly, there is also a need to add many new storage and transportation facilities every year. Among them, corrosive media such as acids and alkalis need to be stored and transported in stainless steel tanks with strong corrosion resistance. The storage tanks are usually required to withstand a certain pressure. There are two main ways to prepare the tank body: one is to use one-piece extrusion molding, and the other is to use plate rolling and welding.

[0003] The assembly of can panels requires multiple people to work together to adjust their positions, relying on experience to ensure roundness. The assembly speed is slow, and handling, positioning, and welding all require manual operation, which can easily lead to fatigue and quality fluctuations. Manual assembly is prone to can panel misalignment, resulting in uneven weld penetration, incomplete weld penetration, or burn-through. It is necessary to roll the panels into round shape, assemble them, tack weld them, and weld them. Each step is carried out independently. Manual welding or ordinary automatic welding requires multiple starts and stops. Rolling molds and assembly tooling need to be customized, and changing specifications can take half a day to several days. Traditional processes are suitable for large batches, but for small and medium-sized orders, the cost per can increases dramatically. Summary of the Invention

[0023] This invention provides an automatic welding device for vertical storage tanks. It has the following advantages:

[0024] 1. This invention features a modular collaborative design for efficient continuous operation: Through the modular layout of the main fixed frame and the side-suspended frame, a streamlined operation for can sheet input, positioning, splicing, and welding is achieved. The coordinated action of the material handling synchronization mechanism and the displacement linkage mechanism ensures seamless connection between can sheet transfer, rotation positioning, and welding processes, significantly improving efficiency compared to traditional step-by-step operations. The arc-shaped loading slide driven by the elastic bending rod automatically adjusts its height according to the number of can sheets extracted, ensuring that the top can sheets are always in the material handling position, reducing manual intervention and achieving continuous feeding.

[0025] 2. This invention features high-precision positioning and splicing technology: the traction rod and drive screw of the central sleeve shaft form a double guide to ensure the lateral displacement accuracy of the material picking synchronization mechanism; the external sleeve shaft drives the column shaft to rotate through gear-gear ring transmission, and the hydraulic pressure plate of the clamping top contact mechanism cooperates with the inner disc to apply dynamic pressure to the first and last can pieces, eliminating splicing gaps; the suspended mold cylinder serves as a forming mold to ensure the roundness of the cylinder.

[0026] 3. This invention features intelligent linkage control to reduce operational complexity: the inclined triggering mechanism of the contact plate and the contact crank, and the automatic rebound design of the snap ring structure enable a fully automatic process of material picking-release-positioning. Operators only need to monitor the operation of the equipment. The buffering characteristics of the elastic bending rod can cope with the fluctuation of the stacking height of the cans and avoid mechanical jamming. The redundant stroke of the linkage sleeve allows for self-correction of small positioning deviations.

[0027] 4. This invention features compactness and scalability: the cantilever design of the side-suspended frame and main frame saves ground space and is suitable for narrow workshop environments; the vertical stacking feeding of the arc-shaped storage slide reduces lateral footprint; by changing the size of the suspended mold cylinder and adjusting the stroke of the drive screw, it can be adapted to the manufacturing of storage tanks of different diameters, with strong scalability; through mechanical linkage design, complex processes are simplified into automated processes, achieving industry-leading levels in positioning accuracy, welding quality, and energy efficiency ratio, and is particularly suitable for the efficient production of small and medium batches of multi-specification storage tanks, providing standardized manufacturing solutions for pressure vessels, chemical storage and transportation, and other fields.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see the appendix Figure 1 -Appendix Figure 4 This invention provides an automatic welding device for a vertical storage tank, comprising: a main fixed frame 1 for fixing the automatic welding device structure of the vertical storage tank; a side-suspended frame 2 located on the main fixed frame 1 for installing the displacement drive structure of the welding components; a suspended mold cylinder 3 located on the main fixed frame 1 as a tank piece splicing mold during tank welding; the side-suspended frame 2 fixedly connected to one side of the main fixed frame 1, and the parallel shaft frame structure of the side-suspended frame 2 fixed on the side-suspended frame 2; and a drive gear component of the side-suspended frame 2 disposed on the side-suspended frame 2. The suspended mold cylinder 3 is suspended and fixed on the top of the main fixed frame 1. The can-piece input mechanism 4 is located on the side of the main fixed frame 1 away from the side suspended frame 2 and on the side of the input port of the suspended mold cylinder 3. The displacement linkage mechanism 5 is set on the parallel shaft frame structure of the side suspended frame 2 and extends through the interior of the suspended mold cylinder 3 to the top of the can-piece input mechanism 4. The material picking synchronization mechanism 6 is sleeved and movable on the displacement linkage mechanism 5. The cross welding mechanism 7 is sleeved on the material picking synchronization mechanism 6. The clamping top contact mechanism 8 is embedded in the suspended mold cylinder 3. Firstly, the main equipment Welding operations are performed on the cylindrical tank bodies of small and medium-sized vertical storage tanks. This involves sequentially feeding in raw tank sheet materials, then assembling them into the tank body. Laser welding is then applied to the assembled sections. The overall equipment structure is fixedly installed via a main fixed frame 1. A side-suspended frame 2, mounted on the side of the main fixed frame 1, houses a displacement linkage mechanism 5 that can drive rotation via its parallel shaft frame structure. The suspended mold cylinder 3, which primarily supports the raw tank sheet materials and serves as the tank body assembly mold, is mounted on top of the main fixed frame 1. The raw materials for canned food are stacked on the canned food input mechanism 4, which is fixed to the input port of the suspended mold cylinder 3. At the same time, by activating the displacement linkage mechanism 5, the material picking synchronization mechanism 6 is driven to move, and the raw materials preloaded by the canned food input mechanism 4 are sequentially transferred into the suspended mold cylinder 3. The clamping and top contact mechanism 8 installed inside the suspended mold cylinder 3 is used to fix the first and last raw materials fed in. Then, the material picking synchronization mechanism 6 drives the cross welding mechanism 7 to perform laser welding to fix the joints of adjacent canned food.

[0044] Please see the appendix Figure 1 -Appendix Figure 7The can sheet input mechanism 4 is located on the side suspension frame 2 and is used to input the can sheet raw materials required for tank welding. The can sheet input mechanism 4 includes a bottom slide 41 and an arc-shaped placement slide 42. The bottom slide 41 is fixedly installed on the side of the main fixed frame 1 away from the side suspension frame 2. The arc-shaped placement slide 42 is slidably embedded in the interior of the bottom slide 41. An elastic bending rod 43 connects the bottom of the arc-shaped placement slide 42 and the bottom wall of the bottom slide 41. The bottom slide 41 included in the can sheet input mechanism 4 is fixed on one side of the main fixed frame 1 and located at the input port of the suspension mold cylinder 3, which is used to input the can sheet raw materials required for tank splicing. The stacked raw materials slide on an arc-shaped shelf 42 within the bottom carriage 41. The large stack of raw materials drives the arc-shaped shelf 42 to descend along the bottom carriage 41, compressing the elastic bending rod 43 installed at the bottom of the bottom carriage 41. After the topmost canned material detaches from the stacked canned material on the arc-shaped shelf 42, the compression force of the elastic bending rod 43 drives the arc-shaped shelf 42 to rise along the bottom carriage 41, pushing the new canned material to the top. This process continues, ensuring that all the stacked canned material can be pushed to the contact height of the traction rod 66 when the upper material is extracted.

[0045] Please see the appendix Figure 1 -Appendix Figure 9The displacement linkage mechanism 5 is located on the side suspension frame 2. It works in conjunction with the parallel shaft frame structure, drive gear components, and bottom slide 41 of the side suspension frame 2 to drive the displacement of the canned material extraction and welding structure. The displacement linkage mechanism 5 includes a central sleeve shaft 51 and an outer sleeve shaft 52. The central sleeve shaft 51 is fixedly embedded in the side of the parallel shaft frame structure of the side suspension frame 2 away from the suspension mold cylinder 3. The outer sleeve shaft 52 is sleeved on the central sleeve shaft 51 and rotatably embedded in the side of the parallel shaft frame structure of the side suspension frame 2 near the suspension mold cylinder 3. The drive screw 53 is rotatably embedded inside the central sleeve shaft 51. The traction rod of the central sleeve shaft 51... The structure is fixed at one end of the central sleeve shaft 51 near the suspension mold cylinder 3. The row of shafts 54 are fixed in a rectangular distribution on the side of the outer sleeve shaft 52 near the suspension mold cylinder 3. The drive screw 53, the traction rod structure of the central sleeve shaft 51, and the row of shafts 54 pass through the interior of the suspension mold cylinder 3 and extend to the outside of the bottom slide 41. The contact plate 55 is fixedly connected to the end of the row of shafts 54 away from the outer sleeve shaft 52. The side of the contact plate 55 facing the row of shafts 54 has an arc-shaped conical structure. The outer wall of the outer sleeve shaft 52 is provided with a toothed ring structure that meshes with the drive gear structure of the side suspension frame 2. The central sleeve shaft 51 A drive motor element is installed on the upper part, and is connected to one end of the drive screw 53 via a keyway at the output shaft end of the drive motor element. The displacement linkage mechanism 5 includes a central sleeve shaft 51 and an external sleeve shaft 52, which are mounted on the parallel shaft frame structure of the side suspension frame 2. The external sleeve shaft 52 rotates relative to the central sleeve shaft 51. The drive screw 53, which is rotatably embedded inside the central sleeve shaft 51, and the traction rod structure added to the side wall of the central sleeve shaft 51 pass through the suspension mold cylinder 3 and extend to the bottom slide 41. The rotation of the drive screw 53 and the guidance of the traction rod of the central sleeve shaft 51 can drive the drive screw 53 installed on the side suspension frame 2. The material-picking synchronization mechanism 6 on the displacement linkage mechanism 5 moves laterally, while the column shafts 54 mounted on the external sleeve shaft 52 in a rectangular distribution also pass through the suspension mold cylinder 3 and extend to the bottom slide 41. The drive gear of the side suspension frame 2 drives the gear ring structure of the external sleeve shaft 52 to rotate, and at the same time drives the material-picking synchronization mechanism 6 mounted on the column shafts 54 to rotate in the suspension mold cylinder 3 while carrying the canned material. The contact plate 55 mounted at the end of the column shafts 54 will contact the material-picking synchronization mechanism 6 when the material-picking synchronization mechanism 6 moves to the end, and drive the material-picking synchronization mechanism 6 to unfold, adsorb and extract the canned material.

[0046] Please see the appendix Figure 1 -Appendix Figure 11The material handling synchronization mechanism 6 is located on the displacement linkage mechanism 5. It works in conjunction with the traction rod structure of the central sleeve shaft 51, the drive screw 53, the row of shafts 54, and the contact plate 55 to extract and transport the raw materials required for the storage tank. The material handling synchronization mechanism 6 includes a first linkage sleeve 61, a second linkage sleeve 62, and a nut auxiliary wheel 63. The first linkage sleeve 61 and the second linkage sleeve 62 are embedded side-by-side between the row of shafts 54 and slide along the row of shafts 54. The first linkage sleeve 61 is closer to the raw material input mechanism 4 than the second linkage sleeve 62. The nut auxiliary wheel 63 is rotatably embedded inside the first linkage sleeve 61, while its inner threaded end is helically sleeved on the outer threaded surface of the drive screw 53. The nut auxiliary wheel 63 slides on the traction rod structure of the central sleeve shaft 51. A retaining spring structure is fixedly connected between linkage sleeve 1 61 and linkage sleeve 2 62. A contact crank 64 is rotatably connected to the top of linkage sleeve 1 61 near the contact plate 55. The contact crank 64 consists of a short-pitch rod and a long-pitch rod. The short-pitch rod of the contact crank 64 is close to the contact plate 55, while the long-pitch rod has a groove. A traction drag rod 65 is fixedly installed on the top of linkage sleeve 2 62. The end of the traction drag rod 65 away from linkage sleeve 2 62 is embedded and slides in the groove of the long-pitch rod structure of the contact crank 64. A straight rail structure is provided at the bottom of linkage sleeve 1 61, and a traction slide rod 66 is slidably installed through the straight rail structure. A suction cup structure distributed along an arc is provided at the bottom of the traction slide rod 66. A rotatably connected... Linkage push rod 67, with one end of linkage push rod 67 away from linkage sleeve 62 rotatably connected to traction slide rod 66. The material taking synchronization mechanism 6 includes linkage sleeve 1 61 and linkage sleeve 2 62, which are displaced and installed in parallel on the column shaft 54. The nut auxiliary wheel 63 embedded and rotating in linkage sleeve 1 61 will engage with the thread on the outer surface of the drive screw 53. The snap ring structure installed between linkage sleeve 1 61 and linkage sleeve 2 62 will drive linkage sleeve 2 62 to approach linkage sleeve 1 61 while simultaneously retracting due to elasticity. The traction rod structure of the central sleeve shaft 51 passes through the nut auxiliary wheel 63, preventing the nut auxiliary wheel 63 from rotating on the drive screw 53. When the drive screw 53 rotates, it will drive the nut auxiliary wheel 63 to drive the linkage sleeve. Linkage sleeve 61 and linkage sleeve 62 move along the column shaft 54 ​​and reach the top of the arc-shaped placement slide 42 through the output port of the suspension mold cylinder 3. The abutting crank 64 installed on the top of linkage sleeve 61 will abut against the arc-shaped cone structure of the abutting plate 55. When the short-pole structure of the abutting crank 64 contacts the arc-shaped cone structure, it will move along the arc-shaped inclined surface and drive the long-pole structure of the abutting crank 64 to rotate along linkage sleeve 61. The long-pole structure of the abutting crank 64 drives the traction slide rod 66 installed on the top of linkage sleeve 62 to move through its own slide groove, driving linkage sleeve 62 to move closer to linkage sleeve 61 along the column shaft 54. The linkage push rod 67 installed at the bottom of linkage sleeve 62 will move due to the movement of linkage sleeve 62.The traction slide rod 66, which slides along the straight rail structure at the bottom of the linkage sleeve 61, moves downward and causes the suction cup structure distributed in an arc at the bottom of the traction slide rod 66 to contact and adsorb the uppermost can sheet structure. Then, the linkage sleeve 61 is driven back by the drive screw 53. After the short-pitch rod structure of the abutting crank 64 disengages from the abutting disk 55, the linkage sleeve 62 retracts and moves away from the linkage sleeve 61 under the action of the snap ring structure. At the same time, the traction slide rod 66, under the traction of the linkage push rod 67, drives the adsorbed can sheet material to rise and is guided by the linkage sleeve 61 into the suspension mold cylinder 3 until the linkage sleeve 62 moves and touches the side wall of the embedded disk 81 included in the clamping and contacting mechanism 8. At this time, the linkage sleeve 62 begins to move towards the linkage. The first sleeve 61 moves closer, driving the traction slide rod 66 to push the canned material towards the side wall of the suspension mold cylinder 3 until the canned material adheres to the inside of the suspension mold cylinder 3. This ensures that all stacked canned material is pushed to the contact height of the traction slide rod 66 during the extraction of the upper material, and is then sequentially drawn into the suspension mold cylinder 3 by the traction slide rod 66. Simultaneously, the outer sleeve shaft 52 and the row shaft 54 ​​drive the first and second linkage sleeves 61 and 62 to rotate inside the suspension mold cylinder 3, causing the canned material to be spliced ​​along the inner wall of the suspension mold cylinder 3 into the required cylindrical shape of the storage tank. The drive screw 53 drives the first and second linkage sleeves 61 and 62 to move, simultaneously causing the cross-welding mechanism 7 installed on the second linkage sleeve 62 to move as well.

[0047] Please see the appendix Figure 1 -Appendix Figure 12 The cross-welding mechanism 7 is located on the material handling synchronization mechanism 6 and works in conjunction with the linkage sleeve 2 62 to synchronously weld the assembled can sheet raw materials. The cross-welding mechanism 7 includes an arc-shaped sleeve 71. The inner side of the arc-shaped sleeve 71 is provided with a rectangularly distributed slot structure, which engages and slides on the row shaft 54 ​​through the slot structure. The arc-shaped sleeve 71 is sleeved and fixed on the linkage sleeve 2 62. The bottom of the arc-shaped sleeve 71 is provided with a corresponding extension arm 72. The outer end of the extension arm 72 is provided with a laser welding head element, which drives the cross-welding mechanism 7 installed on the linkage sleeve 2 62 to move. The arc-shaped sleeve 71 included in the cross-welding mechanism 7 utilizes... The arc-shaped sleeve 71 is wrapped around the column shaft 54 ​​by its own fitting groove structure. This allows the arc-shaped sleeve 71 to rotate while being driven by the column shaft 54. At the same time, it can also be driven by the traction displacement of the linkage sleeve 2 62 to move the extension arm 72 installed at the bottom of the arc-shaped sleeve 71 and the laser welding head structure set at the end of the extension arm 72 along the splicing of adjacent tank pieces. At the same time, the splicing is welded, so that the adjacent tank pieces are fixed to each other. Then, the arc-shaped sleeve 71 and the extension arm 72 are driven to rotate by the column shaft 54, thereby covering all the intersections of adjacent tank pieces, driving the spliced ​​cylindrical tank pieces to be welded and fixed to each other, and finally forming the shape.

[0048] Please see the appendix Figure 1 -Appendix Figure 13The clamping top contact mechanism 8 is located on the suspended mold cylinder 3 and works with the row shaft 54 ​​to synchronously clamp the spliced ​​can sheet material. The clamping top contact mechanism 8 includes an embedded disc 81. The embedded disc 81 has rectangularly distributed fitting grooves at its center and is sleeved on the row shaft 54 ​​through the fitting grooves. The embedded disc 81 is embedded into the interior of the suspended mold cylinder 3 and away from the input port of the suspended mold cylinder 3. The side wall of the embedded disc 81 is provided with upper and lower opposing pressing members 82. The pressing member 82 includes a hydraulic drive component that outputs outward and an arc plate structure that fixes the telescopic end. The linkage sleeve 2 62 begins to move closer to the linkage sleeve 1 61 and drives the traction slide rod 66 to push the can sheet towards the side wall of the suspended mold cylinder 3 until the can sheet adheres to the interior of the suspended mold cylinder 3. At this time, the pressing member 82 installed on the embedded disc 81 will press and stabilize the first can sheet in the suspended mold cylinder 3 through the hydraulic drive component and the pressure plate structure.

[0049] Working Principle: This equipment is primarily designed for welding cylindrical tank bodies of small and medium-sized vertical storage tanks. It works by sequentially inputting raw material tank panels, which are then assembled into the tank body. Laser welding is performed on the assembled sections. The overall equipment structure is fixedly installed via a main fixed frame 1. A side-suspended frame 2, mounted on the side of the main fixed frame 1, houses a displacement linkage mechanism 5 that drives rotation via its parallel shaft frame structure. A suspended mold cylinder 3, which bears the raw material tank panels and serves as the tank assembly mold, is mounted on top of the main fixed frame 1. The raw material tank panels are stacked on a panel input mechanism 4, which is fixed to the input port of the suspended mold cylinder 3. The displacement linkage mechanism is activated simultaneously. Structure 5 drives the material feeding synchronization mechanism 6 to move and sequentially transfers the preloaded can sheet raw materials from the can sheet input mechanism 4 into the suspension mold cylinder 3. The clamping and top contact mechanism 8 installed inside the suspension mold cylinder 3 fixes the first and last can sheet raw materials fed in. Then, the material feeding synchronization mechanism 6 drives the cross welding mechanism 7 to perform laser welding and fixation on the splice of adjacent can sheets. First, the bottom slide 41 included in the can sheet input mechanism 4 is fixed on one side of the main fixed frame 1 and located at the input port of the suspension mold cylinder 3. The can sheet raw materials spliced ​​in the can body are stacked and stacked on the arc-shaped placement slide 42 that slides inside the bottom slide 41. The large number of stacked raw materials drive the arc-shaped placement slide 42 to descend along the bottom slide 41 and compress the elastic bending rod 4 installed at the bottom of the bottom slide 41. 3. The central sleeve shaft 51 and the externally sleeved outer sleeve shaft 52 of the displacement linkage mechanism 5 are mounted on the parallel shaft frame structure of the side suspension frame 2. The outer sleeve shaft 52 rotates relative to the central sleeve shaft 51. The drive screw 53 embedded inside the central sleeve shaft 51 and the traction rod structure added to the side wall of the central sleeve shaft 51 pass through the suspension mold cylinder 3 and extend to the bottom slide 41. The rotation of the drive screw 53 and the guidance of the traction rod of the central sleeve shaft 51 can drive the material picking synchronization mechanism 6 added to the displacement linkage mechanism 5 to move laterally. The row shafts 54 of the outer sleeve shaft 52, which are installed in a rectangular distribution, also pass through the suspension mold cylinder 3 and extend to the bottom slide 41. The drive gear of the side suspension frame 2 drives the gear ring of the outer sleeve shaft 52. The structure rotates, simultaneously driving the material-picking synchronization mechanism 6, which is sleeved on the column shaft 54, to rotate within the suspension mold cylinder 3 while carrying the canned material. The contact plate 55, attached to the end of the column shaft 54, contacts the material-picking synchronization mechanism 6 when it reaches its end, causing the mechanism to unfold, absorb, and extract the canned material. The material-picking synchronization mechanism 6 includes a first linkage sleeve 61 and a second linkage sleeve 62, which are mounted side-by-side on the column shaft 54. The nut auxiliary wheel 63, embedded and rotating within the first linkage sleeve 61, engages with the threaded outer surface of the drive screw 53. The retaining spring structure between the first linkage sleeve 61 and the second linkage sleeve 62 causes the second linkage sleeve 62 to approach the first linkage sleeve 61 while simultaneously retracting due to its elasticity.The traction rod structure of the central sleeve shaft 51 passes through the nut auxiliary wheel 63, preventing the nut auxiliary wheel 63 from rotating on the drive screw 53. When the drive screw 53 rotates, it drives the nut auxiliary wheel 63 to move the linkage sleeve one 61 and linkage sleeve two 62 along the column shaft 54 ​​and reach the top of the arc-shaped placement slide 42 along the output port of the suspension mold cylinder 3. The abutting crank 64 installed on the top of the linkage sleeve one 61 will abut against the arc-shaped cone structure of the abutting disk 55. When the short-pitch rod structure of the abutting crank 64 contacts the arc-shaped cone structure, it will move along the arc-shaped inclined surface and drive the long-pitch rod structure of the abutting crank 64 to rotate along the linkage sleeve one 61. The long-pitch rod structure of the abutting crank 64 drives the linkage sleeve two 62 to rotate through its own groove. The displacement of the traction slide rod 66 drives the second linkage sleeve 62 to move closer to the first linkage sleeve 61 along the column shaft 54. The linkage push rod 67 installed at the bottom of the second linkage sleeve 62, due to the movement of the second linkage sleeve 62, pushes the traction slide rod 66, which slides along the vertical rail structure at the bottom of the first linkage sleeve 61, downwards. This causes the suction cup structure at the bottom of the traction slide rod 66, which is distributed in an arc, to contact and adsorb the uppermost canned material structure. Then, the drive screw 53 drives the first linkage sleeve 61 to retract. After the short-pitch rod structure of the contact crank 64 disengages from the contact plate 55, the second linkage sleeve 62 retracts and moves away from the first linkage sleeve 61 under the action of the snap ring structure. Simultaneously, the traction slide rod 66, under the traction of the linkage push rod 67, causes the adsorbed canned material to rise, and is simultaneously pulled upwards by the linkage sleeve. The first piece of can is guided into the suspension mold cylinder 3 by the first piece of can 61 until the second piece of can 62 moves and contacts the side wall of the inner plate 81 included in the clamping contact mechanism 8. At this time, the second piece of can 62 begins to move closer to the first piece of can 61 and drives the traction slide rod 66 to push the can piece towards the side wall of the suspension mold cylinder 3 until the can piece adheres to the inside of the suspension mold cylinder 3. At this time, the clamping member 82 installed on the inner plate 81 will press and stabilize the first piece of can piece in the suspension mold cylinder 3 through the hydraulic drive member and the pressure plate structure. After the uppermost piece of can detaches from the can pieces stacked on the arc-shaped placement slide 42, the compression force of the elastic bending rod 43 drives the arc-shaped placement slide 42 to rise along the bottom slide 41 and push the new piece of can material to the top. In this way, all the stacked pieces can be driven. When the raw material for canning is extracted from the upper part, it can be pushed to the contact height of the traction slide bar 66, and then sequentially drawn into the suspension mold cylinder 3 by the traction slide bar 66. At the same time, the external sleeve shaft 52 and the row shaft 54 ​​drive the linkage sleeve one 61 and linkage sleeve two 62 to rotate inside the suspension mold cylinder 3, so that the raw material for canning is spliced ​​along the inner wall of the suspension mold cylinder 3 into the cylindrical shape required for the storage tank. The drive screw 53 drives the linkage sleeve one 61 and linkage sleeve two 62 to move, and at the same time drives the cross welding mechanism 7 installed on the linkage sleeve two 62 to move. The arc-shaped sleeve 71 included in the cross welding mechanism 7 uses its own fitting groove structure to wrap around the row shaft 54, so that the arc-shaped sleeve 71 can be rotated by the row shaft 54.Alternatively, the traction displacement of the linkage sleeve 2 62 can drive the extension arm 72, which is installed at the bottom of the arc-shaped sleeve 71, and the laser welding head structure at the end of the extension arm 72, to move along the splice of adjacent tank pieces, and simultaneously weld the splice, thus fixing the adjacent tank pieces together. Then, the arc-shaped sleeve 71 and the extension arm 72 can be rotated by the column shaft 54, thereby covering all the intersections of adjacent tank pieces, driving the spliced ​​cylindrical tank pieces to be welded and fixed together, and finally forming the final shape.
