Detailed Implementation

[0010] The following is a reference appendix. Figures 1-22 The described embodiments are exemplary and intended to explain embodiments of the invention, and should not be construed as limiting the invention.

[0011] In this embodiment, as Figure 1 As shown, an automated metal can forming equipment is provided, which can process at least 900 metal sheets into the shape shown. Figures 20-22 The state of the process. Specifically, the automated metal can forming equipment includes a first frame 100 and a second frame 200. The first frame 100 is equipped with a metal sheet feeding device 300 for conveying metal sheets 900, a metal sheet hooking device 400 for hooking the two ends of the metal sheets 900, and a can body forming and fastening device 500 for fastening the hooked metal sheets 900 into a can body 1000. Between the second frame 200 and the first frame 100, there is a can body feeding device 600 for conveying the can body 1000 from the can body forming and fastening device 500 to the second frame 200. The second frame 200 is equipped with a bottom sheet feeding device 700 for conveying bottom sheets, and a multi-functional can body processing device 800 for receiving the can body 1000 conveyed by the can body feeding device 600 and the bottom sheet conveyed by the bottom sheet feeding device 700 and performing fastening processing on the can body 1000 and the bottom sheet.

[0012] In this embodiment, the metal sheet 900 is fed by the metal sheet feeding device 300 to the metal sheet hooking device 400 for hooking at the end. After hooking, the metal sheet 900 is fed by the metal sheet feeding device 300 to the can body forming and fastening device 500 to fasten the hooks of the metal sheet 900 to form the can body 1000. The can body 1000 is then fed by the can body feeding device 600 between the first frame 100 and the second frame 200 to the can body multi-functional processing device 800. The bottom sheet feeding device 700 then feeds the bottom sheet to the can body multi-functional processing device 800. In this way, the can body 1000 and the bottom sheet are processed and fastened together by the can body multi-functional processing device 800 to complete the automated processing operation.

[0013] In this embodiment, as Figure 2As shown, the metal sheet feeding device 300 includes a metal sheet stacking rack 301, a vacuum suction cup 302, a suction cup connecting rod 303, a metal sheet unloading eccentric wheel 304, a metal sheet unloading rotating shaft 305, a metal sheet translation scraper 306, a scraper connecting block 307, a metal sheet translation connecting rod 308, a metal sheet translation eccentric wheel 309, and a metal sheet translation rotating shaft 310. The metal sheet stacking rack 301 is installed on the first frame 100. The vacuum suction cup 302, suction cup connecting rod 303, metal sheet unloading eccentric wheel 304 and metal sheet unloading rotating shaft 305 are all located below the metal sheet stacking rack 301. The metal sheet unloading rotating shaft 305 passes through the eccentric hole connecting the metal sheet unloading eccentric wheel 304. The suction cup connecting rod 303 is arranged vertically and connected between the vacuum suction cup 302 and the metal sheet unloading eccentric wheel 304. The metal sheet unloading eccentric wheel 304 is rotated by the metal sheet unloading rotating shaft 305. The vacuum suction cup 302 is moved up and down through the suction cup connecting rod 303 to adsorb the metal sheets 900 located in the metal sheet stacking rack 301. The first frame 100 is provided with a horizontally arranged clearance zone 101. The metal sheet translation scraper 306 is horizontally arranged in the clearance zone 101. The scraper connecting block 307 is vertically arranged and connected to the bottom of the metal sheet translation scraper 306. The metal sheet translation eccentric wheel 309 is connected to the metal sheet translation shaft 310. The metal sheet translation connecting rod 308 is connected between the eccentric hole of the metal sheet translation eccentric wheel 309 and the scraper connecting block 307. The metal sheet translation shaft 310 drives the rotation of the metal sheet translation eccentric wheel 309. The metal sheet translation connecting rod 308 drives the scraper connecting block 307 and the metal sheet translation scraper 306 connected to the scraper connecting block 307 to move horizontally back and forth to transfer the metal sheet 900 adsorbed by the vacuum suction cup 302 to the metal sheet folding hook device 400 and the can body forming and fastening device 500. Specifically, the metal sheet stacking rack 301 stacks multiple metal sheets 900. When the metal sheet feeding shaft 305 is driven to rotate, it drives the metal sheet feeding eccentric wheel 304, which in turn drives the vacuum suction cup 302 set on it to rise and fall intermittently through the vertically arranged suction cup connecting rod 303. Each time it rises, it picks up a metal sheet 900 on the metal sheet stacking rack 301. When it falls to a suitable position, the rotation of the metal sheet translation shaft 310 drives the metal sheet translation eccentric wheel 309 to rotate. When the metal sheet translation eccentric wheel 309 rotates, it drives the metal sheet translation connecting rod 308 to rotate eccentrically, thereby reciprocatingly driving the scraper connecting block 307 and the metal sheet translation scraper connecting block 306 connected to it to translate. Then, the metal sheet 900 picked up by the vacuum suction cup 302 can be scraped and sent to the metal sheet folding hook device 400 for folding operation.

[0014] In this embodiment, as Figure 3As shown, the metal sheet folding hook device 400 includes an upper folding hook mechanism 401, an inner folding hook mechanism 402, and a rolling mechanism 403. The upper folding hook mechanism 401 is installed on one side of the clearance zone 101 and is used to bend the first end of the metal sheet 900 to form a V-shaped upper folding hook. The inner folding hook mechanism 402 is installed on the other side of the clearance zone 101 and spaced apart from the upper folding hook mechanism 401. It is used to bend the second end of the metal sheet 900 to form a V-shaped inner folding hook, which can engage with the V-shaped upper folding hook. The rolling mechanism 403 is disposed outside the upper folding hook mechanism 401 and the inner folding hook mechanism 402, and is used to simultaneously apply force to the upper folding hook mechanism 401 and the inner folding hook mechanism 402 to drive the upper folding hook mechanism 401 and the inner folding hook mechanism 402 to respectively process a V-shaped upper folding hook at the first end and a V-shaped inner folding hook at the second end of the metal sheet 900 for engagement. Specifically, the roller pressing mechanism 403 applies force to the upper hook mechanism 401 and the inner hook mechanism 402 simultaneously. In this way, the spaced upper hook mechanism 401 and inner hook mechanism 402 can bend the first and second ends of the metal sheet 900 that has passed through the metal sheet hook device 400 to form V-shaped upper hooks and V-shaped inner hooks, respectively. This achieves automation and allows for the one-time processing of hooks of different shapes that can be riveted together at both ends of the metal sheet 900 in a single process. The structure is ingeniously designed, with high production efficiency and good production quality.

[0015] In this embodiment, as Figures 3-4As shown, the upper folding hook mechanism 401 includes an upper folding hook base 4011, an upper folding hook connecting shaft 4012, an upper folding hook outer swing frame 4013, an upper folding hook inner swing frame 4014, an upper folding hook flat pressing block 4015, an upper folding hook upper mold 4016, and an upper folding hook lower mold 4017. The upper folding hook connecting shaft 4012 and the upper folding hook lower mold 4017 are respectively located at both ends of the upper folding hook base 4011. One end of the upper folding hook outer swing frame 4013 and the upper folding hook inner swing frame 4014 are rotatably connected to the upper folding hook connecting shaft 4012 through bearings, and the upper folding hook outer swing frame 4013 surrounds the upper folding hook inner swing frame 4014. The tops of frame 4013 and inner swing frame 4014 of the upper fold hook can be subjected to pressure applied by roller pressing mechanism 403. The bottoms of outer swing frame 4013 and inner swing frame 4014 of the upper fold hook are respectively connected to the base 4011 of the upper fold hook through a return spring. The flat pressing block 4015 and upper mold 4016 of the upper fold hook are respectively connected to the bottom of the other end of outer swing frame 4013 and inner swing frame 4014 of the upper fold hook, and are both located above the lower mold 4017 of the upper fold hook. The lower mold 4017 of the upper fold hook is provided with a V-shaped vertical groove of the upper fold hook, and the upper mold 4016 of the upper fold hook is provided with a V-shaped vertical block of the upper fold hook that corresponds to and cooperates with the V-shaped vertical groove of the upper fold hook. Specifically, during the processing, one end of the metal sheet 900 is conveyed above the upper hook lower die 4017. At this time, the tops of the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 are respectively subjected to pressure applied by the roller pressing mechanism 403 when it performs its work. Since the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 are staggered, both of them can swing downward with the upper hook connecting shaft 4012 as the axis. In this way, the upper hook flat pressing block 4015 and the upper hook upper die 4016 are respectively driven to press down. In this design, the upper hook flat pressing block 4015 presses down on the area of ​​the metal sheet 900 that is relatively far from its end. The upper hook upper die 4016 presses down on the end of the metal sheet 900, and the upper hook V-shaped vertical block presses the end of the metal sheet 900 into the upper hook V-shaped vertical groove, so that the end of the metal sheet 900 forms a shape formed by the upper hook V-shaped vertical groove and the upper hook V-shaped vertical block, thus forming a V-shaped upper hook. At the same time, the other end of the metal sheet 900 is processed into a V-shaped inner hook by the inner hook mechanism 402. The upper hook mechanism 401 has a very ingenious structural design and can effectively process V-shaped upper hooks. Furthermore, as the roller pressing mechanism 403 continues to operate, it will disengage from the pressure on the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 for a period of time. Then, under the action of the return spring, both the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 will reset to meet and wait for the processing of the end of the next metal sheet 900.

[0016] In this embodiment, as Figure 3 , 5As shown, the inner folding hook mechanism 402 includes an inner folding hook base 4020, an inner folding hook connecting shaft 4021, an inner folding hook outer swing frame 4022, an inner folding hook inner swing frame 4023, an inner folding hook push column 4024, an inner folding hook flat pressing block 4025, an inner folding hook upper mold 4026, an inner folding hook lower mold 4027, an inner folding hook side mold 4028, and an inner folding hook hollow seat 4029. The inner folding hook connecting shaft 4021 and the inner folding hook lower mold 4027 are respectively located at both ends of the inner folding hook base 4020, and the inner folding hook hollow seat 4029 is located on the inner folding hook base 4020. The upper part is located between the inner hook connecting shaft 4021 and the inner hook lower mold 4027. The inner hook side mold 4028 is movably disposed within the inner hook hollow seat 4029, and one end of it is connected to the inner hook lower mold 4027 via a return spring. One end of the inner hook outer swing frame 4022 and the inner hook inner swing frame 4023 are rotatably connected to the inner hook connecting shaft 4021 via bearings, and the inner hook outer swing frame 4022 surrounds the inner hook inner swing frame 4023. The bottom of the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 are respectively connected to a return spring. The spring is connected to the hollow seat 4029 of the inner folding hook. The inner folding hook push post 4024 vertically passes through the inner swing frame 4023 of the inner folding hook, and its bottom is connected to the inner folding hook base 4020 through a return spring. The side of the bottom of the inner folding hook push post 4024 is engaged with the other end of the inclined surface of the inner folding hook side mold 4028. The tops of the inner folding hook outer swing frame 4022, the inner swing frame 4023, and the inner folding hook push post 4024 can all be subjected to pressure applied by the roller pressing mechanism 403. The inner folding hook flat pressing block 4025 and the inner folding hook upper mold 4026 are respectively connected to the inner folding hook outer swing frame 4023. The bottom of the other end of the inner swing frame 4023 and the inner fold hook are both located above the lower mold 4027 of the inner fold hook. The end of the lower mold 4027 of the inner fold hook facing the side mold 4028 of the inner fold hook is provided with an inner fold hook V-shaped horizontal column (not shown in the figure). The upper mold 4026 of the inner fold hook is provided with an inner fold hook V-shaped vertical block that corresponds to and cooperates with the inner fold hook V-shaped horizontal column. The side mold 4028 of the inner fold hook can be moved to the bottom of the inner fold hook V-shaped horizontal column by the push of the inner fold hook push column 4024, and a metal sheet 900 spacing is formed between the top surface of the side mold 4028 of the inner fold hook and the bottom surface of the inner fold hook V-shaped horizontal column. Specifically, during the processing, the other end of the metal sheet 900 is conveyed to the top of the inner fold hook lower die 4027. At this time, the tops of the inner fold hook outer swing frame 4022 and inner fold hook inner swing frame 4023 are respectively subjected to pressure applied by the roller pressing mechanism 403 when it performs its work. Since the inner fold hook outer swing frame 4022 and inner fold hook inner swing frame 4023 are staggered, both can swing downward with the inner fold hook connecting shaft 4021 as the axis. In this way, the inner fold hook flat pressing block 4025 and inner fold hook upper die 4026 are respectively driven to press down.In this process, the inner folding hook flat pressing block 4025 presses down on the area of ​​the metal sheet 900 that is relatively far from its end. The inner folding hook upper die 4026 presses down on the end of the metal sheet 900. The inner folding hook V-shaped vertical block presses the end of the metal sheet 900 against the upper surface of the inner folding hook V-shaped horizontal column, so that the end of the metal sheet 900 forms the surface shape formed by the cooperation of the upper inner folding hook V-shaped vertical block and the inner folding hook V-shaped horizontal column. Then, the inner folding hook push column 4024 is pushed down by the roller pressing mechanism 403. The inclined surface at its bottom forces the inner folding hook side die 4028 to move towards the inner folding hook lower die 4027 until the end of the metal sheet 900 formed by the inner folding hook V-shaped vertical block and the inner folding hook V-shaped horizontal column is folded inward and accommodated in the gap of the metal sheet 900 formed between the top surface of the inner folding hook side die 4028 and the bottom surface of the inner folding hook V-shaped horizontal column. In this way, the end of the metal sheet 900 is processed into a V-shaped inner folding hook. Meanwhile, the other end of the metal sheet 900 is processed into a V-shaped upper hook by the upper hook mechanism 401. The inner hook mechanism 402 has a very ingenious structural design, which can effectively process the V-shaped upper hook. Furthermore, as the roller pressing mechanism 403 continues to work, it will disengage from the pressure on the inner hook outer swing frame 4022, the inner hook inner swing frame 4023, and the inner hook push post 4024 for a period of time. Then, under the action of the return spring, the upper hook outer swing frame 4013, the upper hook inner swing frame 4014, and the inner hook push post 4024 will all return to their original positions. This allows the inner hook side mold 4028 to also return to its original position under the action of the return spring, so as to meet and wait for the processing of the end of the next metal sheet 900.

[0017] In this embodiment, as Figure 3As shown, the roller pressing mechanism 403 includes a roller pressing shaft 4031, two support seats 4032 supported at intervals on the roller pressing shaft 4031, and a first roller pressing wheel 4033 and a second roller pressing wheel 4034 fixedly connected to the roller pressing shaft 4031. The roller pressing shaft 4031 is connected to the two support seats 4032 respectively through two bearings. In this way, the roller pressing shaft 4031 can still rotate while being supported by the two support seats 4032. For example, the roller pressing shaft 4031 can be driven to rotate by a belt pulley mechanism. The first roller 4033 is provided with a first outer cam disk 40311 and a first inner cam disk 40312 arranged at intervals. The tops of the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 can respectively abut against the first outer cam disk 40311 and the first inner cam disk 40312 after the rotation angle. Because of the arrangement of the first outer cam disk 40311 and the first inner cam disk 40312, when the roller shaft 4031 drives the first roller 4033 to rotate, the tops of the upper hook outer swing frame 4013 and the upper hook inner swing frame 4014 are applied in a certain order at different time periods. The second roller 4034 is provided with a second outer cam disk 40341, a middle cam disk 40342, and a second inner cam disk 40343 arranged at intervals. The tops of the inner hook outer swing frame 4022, the inner hook inner swing frame 4023, and the inner hook push column 4024 can respectively abut against the second outer cam disk 40341, the middle cam disk 40342, and the second inner cam disk 40343 after rotation. Similarly, because of the arrangement of the second outer cam disk 40341, the middle cam disk 40342, and the second inner cam disk 40343, when the roller shaft 4031 drives the second roller 4034 to rotate, the tops of the inner hook outer swing frame 4022, the inner hook inner swing frame 4023, and the inner hook push column 4024 are applied in a certain order at different time periods.

[0018] In this embodiment, as Figure 6As shown, the can body forming and fastening device 500 includes an upper support 501, a mold core mechanism 502, a pressing mechanism 503, and a pressing frame mechanism 504. The upper support 501 is mounted on the first frame 100, and its bottom front and rear positions are divided into a pressing station and a pressing frame station. The mold core mechanism 502 includes a strip mold core 5021 for carrying the metal sheet 900 conveyed by the metal sheet feeding device 300. The strip mold core 5021 is located below the upper support 501 and is arranged along the direction from the pressing station to the pressing frame station. The pressing mechanism 503 includes a first side hinge mold 5031 and a second side hinge mold 5032. Both the first side hinge mold 5031 and the second side hinge mold 5032 are rotatably connected to the upper support 501. The pressing stations are distributed on both sides of the upper support 501. The first side hinge mold 5031 and the second side hinge mold 5032 can be fastened to the outside of the strip mold core 5021 to achieve initial fastening of the metal sheet 900 located on the strip mold core 5021. The pressing mechanism 504 includes an upper pressing mold body 5041 and a lower pressing mold body 5042 that cooperates with the upper pressing mold body 5041. The upper pressing mold body 5041 is installed on the pressing station of the upper support 501, and the lower pressing mold body 5042 is located below the pressing station. It can cooperate with the upper pressing mold body 5041 to cover the metal sheet 900 located on the strip mold core 5021 and which has been initially fastened, thereby achieving pressing of the fastening position. When the metal sheet 900 is moved above the strip mold core 5021, the metal sheet 900 is initially located at the pressing station at the bottom of the upper frame. At this time, the strip mold core 5021 can be raised to a certain height by the mechanism, and then the first side hinge mold 5031 and the second side hinge mold 5032 of the pressing mechanism 503 can be closed. After the first side hinge mold 5031 and the second side hinge mold 5032 are closed, the metal sheet 900 is covered outside the strip mold core 5021. The hooks at both ends of segment 00 achieve initial engagement. Then, the first side hinge mold 5031 and the second side hinge mold 5032 are opened, and the strip mold core 5021 descends a certain height to continue conveying the initially engaged metal sheet 900 to the pressing station. At this time, the lower pressing can body mold 5042 and the upper pressing can body mold 5041 of the pressing mechanism 504 are closed to achieve pressing of the metal sheet 900 at the engagement position, completing the forming and fastening process of the metal can body 1000. The metal can body forming and fastening device 500 of the present invention can quickly bend the metal sheet 900 for hook engagement at the pressing station, and press the fastening connection position at the hook engagement position at the pressing station, achieving higher production efficiency and better production quality.

[0019] In this embodiment, as Figure 7As shown, the mold core mechanism 502 also includes a mold core support plate 5022, a horizontal connecting plate 5023, and a mold core cam 5024. The mold core support plate 5022 is arranged vertically and its upper end is connected to one end of the strip mold core 5021. The horizontal connecting plate 5023 is connected to the lower side of the mold core support plate 5022. A mold core bearing 50231 is provided at the end of the horizontal connecting plate 5023. A mold core curved groove 50241 is provided on the inner side of the mold core cam 5024. The mold core bearing 50231... 231 is accommodated and abuts against the groove wall of the mold core curved groove 50241. When the mold core bearing 50231 rotates along the mold core curved groove 50241, it can drive the strip mold core 5021 to rise and fall intermittently through the horizontal connecting plate 5023 and the mold core support plate 5022. Specifically, because the mold core cam 5024 has a curved mold core curved groove 50241 on its inner side, when the mold core bearing 50231 rotates relative to the mold core curved groove 50241, The mold core bearing 50231 will intermittently be in different height positions. This will cause the horizontal connecting plate 5023 and the mold core support plate 5022 connected to it to change their height. Since the strip mold core 5021 is connected to the mold core support plate 5022, this will also cause the strip mold core 5021 to intermittently rise and fall. Thus, when the strip mold core 5021 descends, it creates space for the 1000mm metal sheet 900mm of the tank body. Upon entering, as the strip core 5021 rises, it can be positioned at a suitable height to wait for the first side hinge mold 5031 and the second side hinge mold 5032 to close and cover the metal sheet 900 of the can body 1000 outside the strip core 5021, thus achieving the initial engagement of the hooks at both ends of the metal sheet 900 of the can body 1000. Then, after the strip core 5021 descends, it creates space to transport the metal sheet 900 of the can body 1000, which has completed the hook engagement, to the pressing station.

[0020] like Figures 9-10As shown, the pressing mechanism 503 also includes a first side support plate 5033, a first side cam 5034, a first side connecting rod assembly 5035, a second side support plate 5036, a second side cam 5037, and a second side connecting rod assembly 5038. The first side support plate 5033 and the second side support plate 5036 are both vertically arranged and located below the first side hinge mold 5031 and the second side hinge mold 5032, respectively. The upper end of the first side support plate 5033 is connected to the first side hinge mold 5032 via the first side connecting rod assembly 5035. The hinge mold 5031 is connected, and the upper end of the second side support plate 5036 is connected to the second side hinge mold 5032 through the second side connecting rod assembly 5038. The lower end of the first side support plate 5033 is provided with a first side bearing 50331. The inner side of the first side cam 5034 is provided with a first side curved groove 50341. The first side bearing 50331 is accommodated and abuts against the groove wall of the first side curved groove 50341. The inner side of the second side cam 5037 is provided with a first side bearing 50331. The second side curved groove 50371, the second side bearing 50361 is housed in and abuts against the groove wall of the second side curved groove 50371; when the first side bearing 50331 rotates along the first side curved groove 50341, it can drive the first side hinge mold 5031 to swing relative to the upper frame through the first side support plate 5033 and the first side connecting rod assembly 5035; when the second side bearing 50361 rotates along the second side curved groove 50371, it can drive the second side hinge mold 5031 to swing relative to the upper frame through the second side support plate 5033 and the first side connecting rod assembly 5035. The side support plate 5036 and the second side linkage group 5038 drive the second side hinge mold 5032 to swing relative to the upper frame; specifically, the first side support plate 5033, the first side cam 5034 and the first side linkage group 5035 are components that jointly control the first side hinge mold 5031, and the second side support plate 5036, the second side cam 5037 and the second side linkage group 5038 are components that jointly control the first side hinge mold 5031. The two parts are distributed on both sides in a symmetrical or approximately symmetrical arrangement. When the bearing of the first side cam 5034 rotates relative to the first side curved groove 50341, the first side cam 5034 can intermittently rise and fall. Similarly, the second side cam 5037 can do the same. This can drive the first side support plate 5033 and the second support plate to intermittently rise and fall. Through the intermittent rising and falling of the first side support plate 5033 and the second side support plate 5036, the first side connecting rod group 5035 and the second side connecting rod group 5038 can drive the swing angle of the first side hinge mold 5031 and the second side hinge mold 5032, thus controlling the closing or opening of the first side hinge mold 5031 and the second side hinge mold 5032, and realizing the fastening of the hook of the metal sheet 900 of the can body 1000.

[0021] like Figure 8As shown, the bone pressing mechanism 504 also includes a lower mold support plate 5043 and a lower mold cam 5044. The lower mold support plate 5043 is arranged vertically, and the lower bone pressing mold body 5042 is installed on the upper end of the lower mold support plate 5043. A lower mold bearing 50431 is provided at the lower end of the lower mold support plate 5043. A lower mold curved groove 50441 is provided on the inner side of the lower mold cam 5044. The lower mold bearing 50431 accommodates and abuts against the groove wall of the lower mold curved groove 50441. When the lower mold bearing 50431 rotates along the lower mold curved groove 50441, it can drive the lower bone pressing mold body 5042 to rise and fall intermittently through the lower mold support plate 5043. Specifically, because the lower mold cam 5044 has a curved groove 50441 on its inner side, when the lower mold bearing 50431 rotates relative to the curved groove 50441, the lower mold bearing 50431 will intermittently be in different high and low positions. At this time, the lower mold support plate 5043 can be driven to change its high and low position. Since the lower pressing bone can body mold 5042 is connected to the lower mold support plate 5043, the lower pressing bone can body mold 5042 can be driven to intermittently rise and fall. Thus, when the lower pressing bone can body mold 5042 rises, it can cooperate with the upper pressing bone can body mold 5041 located above to press the bone position of the metal sheet 900 of the can body 1000 after the initial hook fastening is completed, ensuring the stability and reliability of the hook fastening connection.

[0022] In this embodiment, the metal sheet translation scraper 306 is a strip-shaped structure with hooks along its length. Because the metal sheet translation scraper 306 is arranged along the clearance section 101 of the open structure along its length, it spans the metal sheet folding hook device 400 and the can body forming and fastening device 500. Through the reciprocating movement of the metal sheet translation scraper 306, the metal sheet 900 can be scraped to the metal sheet folding hook device 400 for processing, and then scraped to the can body forming and fastening device 500 for further processing. For example, the metal sheet 900 is first scraped by the metal sheet translation scraper 306 to the area between the upper folding hook mechanism 401 and the inner folding hook mechanism 402 for folding hook processing at both ends. After processing, it is scraped to the core mold mechanism 502 and processed by the pressing mechanism 503 and the pressing bone mechanism 504 to form the can body 1000.

[0023] Furthermore, the metal sheet feeding device 300 and the can body forming and fastening device 400 installed in the first frame 100 can be driven by a single motor or by two separate motors. The drive structure can be a chain, belt, connecting rod, or other structures well-known to those skilled in the art, provided that coordination is configured in the software program. Based on the above structural design, those skilled in the art can adapt the appropriate software to control them. Similarly, the can body multi-functional processing device 800 installed on the second frame 200 can also be driven by a single motor. Based on the above structural design, those skilled in the art can adapt the appropriate software to control it.

[0024] In this embodiment, as Figures 11-12As shown, the multi-functional tank body processing device 800 includes a lower template 801, an upper template 802, a polygonal guide post 803, a polygonal guide sleeve 804, a lower mold 805, an upper mold 806, an upper mold fixing block 807, a hinge shearing mechanism 808, a cam divider 809, a rotating disk 810, a fixed cam 811, and a tank body clamping mechanism 812. The cam divider 809 is mounted on the second frame 200, and the cam divider 809 is provided with a rotating flange 8091 located on the outer ring and a fixed flange 8092 located on the inner ring. The rotating disk 810 is fixedly connected to the rotating flange 8091. The rotating disk 810 is provided with radially spaced radial guide seats 8101 and movable holes 8102. The fixed cam 811 is fixedly connected to the fixed flange 8092, and the bottom of the fixed cam 811 is provided with an annular curved groove 8111. The lower mold 805 has a lower limiting groove 8051 for the can body at its top. The upper mold 806 is located above the lower mold 805. The upper mold 806 has a horizontally penetrating shearing mounting cavity 8062 and a vertically penetrating first punching hole 8063 and a second punching hole 8064 arranged side by side at its top. The upper mold 806 has a can body limiting groove 8061 located around the first punching hole 8063 at its bottom. The can body limiting groove 8061 and the lower limiting groove 8051 are used together to limit the upper and lower ends of the can body 1000. The hinge shearing mechanism 808 is installed in the shearing mounting cavity 8062 and passes through the first punching hole 8063 and the second punching hole 8064 respectively to punch the hinge position 1001 of the can body 1000. The upper mold fixing block 807 is sealed on the top of the upper mold 806 to restrict the hinge shearing mechanism 808 from coming out of the shearing mounting cavity 8062. The can body clamping mechanism 812 includes a front end block 8121, a left trapezoidal block 8122, a right trapezoidal block 8123, and a rear end block 8124 with a through hole 8102. The front end block 8121, the left trapezoidal block 8122, the rear end block 8124, and the right trapezoidal block 8123 are arranged sequentially to form a clamping cavity 8125 for clamping the can body 1000. The front end block 8121 and the rear end block 8124 are respectively engaged with the inclined surfaces at both ends of the left trapezoidal block 8122 and the right trapezoidal block 8123. The front end block 8121 is fixed on the rotating disk 810. A radial guide block 81421 extends from the rear end block 8124 and slides through and engages with the radial guide seat 8101. A guide bearing 81242 is provided at the end of the radial guide block 81421. The guide bearing 81242 is accommodated in the annular curved groove 8111.The cam divider 809 drives the rotating disk 810 to rotate, causing the guide bearing 81242 to rotate along the annular curved groove 8111. The pressure applied to the guide bearing 81242 by the annular curved groove 8111 forces the radial guide block 81421 to slide radially along the radial guide seat 8101, thereby forcing the rear end block 8124 to move toward the front end block 8121. Under the action of the inclined surface, the left trapezoidal block 8122 and the right trapezoidal block 8123 can move facing each other to clamp the can body 1000 located in the clamping cavity 8125. The lower mold 805 is installed on the top of the lower template 801 and moves up and down by the drive of the lower template 801. The upper mold 806 is installed on the bottom of the upper template 802 and moves up and down by the drive of the lower template 801. The polygonal guide sleeve 804 is installed in the upper template 802. The polygonal guide post 803 passes through the polygonal guide sleeve 804 and slides up and down with it. The upper mold fixing block 807 is connected to the bottom of the polygonal guide post 803 and moves up and down by the drive of the polygonal guide post 803. As the lower template 801 moves down, it can reach the hinge shearing mechanism 808 to punch the can body 1000 held in the clamping cavity 8125 at the hinge position 1001.

[0025] Specifically, the lower template 801 is used for mounting the lower mold 805, and the upper mold 806 is used for mounting the upper mold 806 and the polygonal guide post 803 and polygonal guide sleeve 804 that slide together. Thus, by driving the lower template 801, the lower mold 805 can be moved, and by driving the upper template 802, the upper mold 806, polygonal guide post 803, and polygonal guide sleeve 804 can be moved. In this way, the movement of the lower mold 805 can be used to position the tank body 1000, and the movement of the upper mold 806 can be used to move the polygonal guide post 803 along with the upper mold 806. After the polygonal guide post 803 drives the upper mold 806 to position the tank body 1000 through the fixing plate of the upper mold 806, the upper template 802 can continue to move until it applies a pressure force to the hinge shearing mechanism 808, thereby realizing the punching of the hinge position 1001 of the tank body 1000. If a polygonal guide post 803 can be a hexagonal guide post, then a hexagonal guide sleeve can also be a hexagonal guide post. The lower mold 805 has a lower limiting groove 8051 on the top of the can body, and the upper mold 806 has an upper limiting groove 8061 on the bottom of the upper mold 806, which together limit the upper and lower ends of the can body 1000. Furthermore, a hinge shearing mechanism 808 is installed in the shearing mounting cavity 8062 in the upper mold 806. The hinge shearing mechanism 808 is sealed and limited by the upper mold fixing block 807 fixed on the upper mold 806. Since the hinge shearing mechanism 808 can enter the can body 1000 through the first punching hole 8063, when it is subjected to external force, it can punch the hinge position 1001 of the can body 1000. That is, it punches the side of the can body 1000 at the position where it passes through the first punching hole 8063 and the second punching hole 8064, forming the hinge position 1001 on the side of the can body 1000. The entire 1001 punching process for the hinge has fewer steps, resulting in high production efficiency. It can maintain consistency in each punching, leading to good production quality.

[0026] In this embodiment, as Figures 13-15As shown, the hinged shearing mechanism 808 includes a first shearing rod 8081, a second shearing rod 8082, a first spring 8083, a second spring 8084, and cooperating concave punches 8085 and convex punches 8086. The first shearing rod 8081 includes a first swing arm 80811, a first force-bearing arm 80812, and a first shearing arm 80813. The first force-bearing arm 80812 and the first shearing arm 80813 are respectively connected to the two ends of the first swing arm 80811 and extend in opposite directions. The second shearing rod 8082 includes a second swing arm 80821, a second force-bearing arm 80822, and a second shearing arm 80823. The second force-bearing arm 80822 and the second shearing arm 80823 are respectively connected to the two ends of the second swing arm 80821 and extend in opposite directions; that is, both the first shearing rod 8081 and the second shearing rod 8082 are approximately Z-shaped. At the connection between the first shear arm 80813 and the first swing arm 80811, a first convex arc portion 80814 and a first concave arc portion 80815 are arranged side by side. At the connection between the second shear arm 80823 and the second swing arm 80821, a second convex arc portion 80824 and a second concave arc portion 80825 are arranged side by side. The second convex arc portion 80824 cooperates with the first concave arc portion 80815, and the second concave arc portion 80825 cooperates with the first convex arc portion 80814, and is connected via a rotating shaft. After the first convex arc portion 80814 and the second convex arc portion 80824 are inserted, they are hinged in the shear mounting cavity 8062. The first shearing rod 8081 and the second shearing rod 8082 formed by this cooperation are similar to pliers or scissors. When the pivot is taken as the axis, because of the cooperation between the second convex arc portion 80824 and the first concave arc portion 80815, and the cooperation between the second concave arc portion 80825 and the first convex arc portion 80814, the two can rotate at the cooperation position without interference. The first shear arm 80813 extends through the first punching hole 8063, and the concave punch 8085 is installed on the side of the first shear arm 80813. The second shear arm 80823 extends through the second punching hole 8064, and the convex punch 8086 is installed on the side of the second shear arm 80823 and is arranged opposite to the concave punch 8085. The first spring 8083 is connected between the first swing arm 80811 and the bottom surface of the shear mounting cavity 8062, and the second spring 8084 is connected between the second swing arm 80821 and the bottom surface of the shear mounting cavity 8062. Under the elastic support force of the first spring 8083 and the second spring 8084, the first shear arm 80813 and the second shear arm 80823 are in the normally open state. When the top of the first force arm 80812 and the second force arm 80822 are subjected to pressure, the first swing arm 80811 and the second swing arm 80821 can be forced to swing around the pivot until the first shear arm 80813 and the second shear arm 80823 are closed. At this time, the concave punch 8085 and the convex punch 8086 cooperate to punch out the hinge position 1001 on the tank body 1000.Under the elastic support force of the first spring 8083 and the second spring 8084, the first shear arm 80813 and the second shear arm 80823 are in the normally open state. When the top of the first force arm 80812 and the second force arm 80822 are subjected to pressure, the first swing arm 80811 and the second swing arm 80821 are forced to swing around the pivot, so that the first swing arm 80811 and the second swing arm 80821 compress the first spring 8083 and the second spring 8084 respectively, until the first shear arm 80813 and the second shear arm 80823 are closed. At this time, the concave punch 8085 and the convex punch 8086 cooperate to punch out the hinge position 1001 on the tank body 1000. When the pressure applied to the top of the first force-bearing arm 80812 and the second force-bearing arm 80822 is removed, the first spring 8083 and the second spring 8084 will respectively support the first swing arm 80811 and the second swing arm 80821, so that they continue to rotate around the pivot, thereby opening the first shear arm 80813 and the second shear arm 80823, waiting to punch the hinge position 1001 of the next can body 1000. The structural design is very ingenious. After the can body 1000 is positioned, the punching of the hinge position 1001 of the can body 1000 can be completed in one step, which is highly efficient and of high quality.

[0027] Furthermore, such as Figures 16-18As shown, multiple can-body clamping mechanisms 812 are provided, and each can-body clamping mechanism 812 is arranged radially around the center of the rotating disk 810. A lateral guide seat 8103 located on the rotating disk 810 is provided between the left trapezoidal block 8122 and the right trapezoidal block 8123 of two adjacent can-body clamping mechanisms 812. A left guide block 81221 and a right guide block 81231 extend from the left trapezoidal block 8122 and the right trapezoidal block 8123 respectively, and are slidably engaged with the lateral guide seat 8103. Adjacent left guide blocks 81221 and right guide blocks 81231 are connected by a tension spring 8104. Specifically, the purpose of arranging multiple radially arranged can-body clamping mechanisms 812 in a ring on a rotating disk 810 is to enable the clamping of multiple can bodies 1000 during continuous operation and to clamp the can bodies 1000 to different workstations for operation. The left guide block 81221 and the right guide block 81231 are inserted into the lateral guide seat 8103 to restrict their movement to the lateral direction only. This allows the left trapezoidal block 8122 and the right trapezoidal block 8123 to either clamp or release the left and right sides of the can body 1000. When the radial guide block 81421 causes the rear end block 8124 to release its clamping of the can body 1000, the inclined surface and the tension spring 8104 quickly cause the left trapezoidal block 8122 and the right trapezoidal block 8123 to release their clamping of the left and right sides of the can body 1000. The structural design is extremely ingenious.

[0028] In this embodiment, multiple lower molds 805 and multiple upper molds 806 can be respectively provided on the lower mold 801 and the upper mold 802, see... Figure 12Multiple lower molds 805 correspond to the positions of the can body clamping mechanism 812. The upper mold 806 at each position moves downwards and cooperates with the corresponding lower mold 805 to perform corresponding processing steps on the can body 1000 at that position. For example, the end of the can body 1000 is rolled, and the bottom sheet is fastened to the bottom of the can body 1000. In this embodiment, the bottom sheet feeding device 700 conveys the bottom sheet to one of the designated lower molds 805 through vibration. In this process station, as the upper mold plate moves downwards... It should be noted that the bottom sheet feeding device 700 in this embodiment uses the prior art where the upper mold 806 on the upper mold plate 802 applies pressure to the can body 1000 after moving downwards, fastening the bottom of the can body 1000 together with the bottom sheet. Currently, the fastening of the substrate to the can body 1000 is existing technology. This technical solution achieves multi-station processing of the can body 1000 through rotational conveying within the multi-functional can body processing device 800. The positions of the other multiple can body clamping mechanisms 812 are designed to facilitate processing of the can body 1000 at those positions, providing sufficient processing stations. For example, the fastening technology between the substrate and the can body 1000 is not within the scope of this application.

[0029] Furthermore, in this embodiment, the can body feeding device 600 is implemented using a belt conveyor mechanism, for example, by clamping the can body 1000 with belts on both sides and driving it to move in one direction. This technology is also a conventional prior art, and its specific structure will not be described in detail in this embodiment.
