[0078] like Figures 1 to 15 As shown, this utility model provides an integrated can-making, filling, and sealing device, which includes:

[0079] The first conveying mechanism 1 is provided with a first film material 3 for forming the bottom of the tank 100. The first conveying mechanism 1 is used to supply and convey the first film material 3. The first film material 3 may be, but is not limited to, a strip-shaped aluminum-plastic composite film.

[0080] The second feeding mechanism 2 is provided with a second film material 4 for forming the can body 200. The second feeding mechanism 2 is used to supply and convey the second film material 4, wherein the second film material 4 may be, but is not limited to, a strip-shaped aluminum-plastic composite film.

[0081] The first punching mechanism 5 is located downstream of the first conveying mechanism 1 along the conveying direction of the first film material 3, and a first conveyor belt 6 is provided below the first punching mechanism 5. The first film material 3 passes through the first punching mechanism 5 and can be punched by the first punching mechanism 5 to form a circular can bottom 100. The output end of the first conveyor belt 6 is connected to the first transfer mechanism 7 to transfer the circular can bottom 100 that has been punched and dropped onto the first conveyor belt 6 to the first transfer mechanism 7. The first transfer mechanism 7 is used to punch and transfer the circular can bottom 100. Of course, it can also be punched to form other shapes (such as rectangles) of can bottom 100 according to actual needs.

[0082] The winding mechanism 8 is located downstream of the second conveying mechanism 2 along the conveying direction of the second film material 4. The inlet of the winding mechanism 8 is connected to the outlet of the second conveying mechanism 2. The winding mechanism 8 is used to wind the second film material 4 into a cylindrical shape. A first welding device 9 is provided on one side of the winding mechanism 8. The first welding device 9 is aligned with the two adjacent edges of the second film material 4, so that after the second film material 4 is wound into a cylindrical shape, the two adjacent edges of the second film material 4 can be welded by the first welding device 9.

[0083] The second punching mechanism 10 is located at or near the discharge port of the winding mechanism 8. The second punching mechanism 10 is used to cut the cylindrical second film 4 that passes through in sequence into multiple segments of a preset length. Each segment of the cylindrical second film 4 is a can body 200, thereby forming the can body 200.

[0084] The second transfer mechanism 11 and the welding turntable 12 are located downstream of and close to the first transfer mechanism 7. The welding turntable 12 is located downstream of the coiling mechanism 8 and close to the outlet of the coiling mechanism 8. A drive roller can be set on the coiling mechanism 8 or at the outlet of the coiling mechanism 8 to drive the formed can body 200 to move downstream and transfer the can body 200 to the welding turntable 12. The can bottom 100 is transferred from the first transfer mechanism 7 to the second transfer mechanism 11. A second welding device 13 is set on one side of the welding turntable 12. The second transfer mechanism 11 is used to transfer the can bottom 100 to the bottom of the can body 200 located on the welding turntable 12 (the can body 200 is transferred to the welding turntable 12 first, and then the corresponding can bottom 100 is transferred). After that, the second welding device 13 can be used to weld the can bottom 100 and the can body 200 to form an unsealed can.

[0085] The second conveyor belt 14 is located downstream of the welding turntable 12. The input end of the second conveyor belt 14 is connected to the welding turntable 12. The output end of the second conveyor belt 14 or a position near the output end is provided with a robot arm 15 and a sealing assembly 16. The robot arm 15 is used to transfer the pre-formed can lid 300 to the top opening of the can body 200 and seal the can lid 300 at the top opening of the can body 200 through the sealing assembly 16.

[0086] The feeding device 17 is located upstream of the sealing assembly 16 along the conveying direction of the second conveyor belt 14. Therefore, before the can lid 300 is installed, the feeding device 17 can quantitatively add contents to the unsealed can body 200. The contents can be any material that needs to be packaged in the can (such as tea, milk powder, coffee, etc.), and the specific type of contents is not limited here.

[0087] In this invention, a first film material 3, serving as the can bottom material, and a second film material 4, serving as the can body material, are provided by a first feeding mechanism 1 and a second feeding mechanism 2, respectively. The first film material 3 is stamped into a circular can bottom 100 by a first punching mechanism 5. This circular can bottom 100 is then stamped into a can bottom 100 by a first transfer mechanism 7, and the formed can bottom 100 is transferred to the welding turntable 12 via the cooperation of the first transfer mechanism 7 and the second transfer mechanism 11. The second film material 4 is rolled and welded by a winding mechanism 8 to form a cylindrical shape that fits the can bottom 100. During the process of passing through the second punching mechanism 10, the cylindrical second film material 4 is cut into multiple segments of a preset length (i.e., forming multiple can bodies 200). The can bodies 200 are transferred to the welding turntable 12 and then cooperate with the can bottom 100. The bottom of the can 100 is transferred to the bottom position of the corresponding can body 200, and the two can be welded directly to form an unsealed can. After the unsealed can is conveyed to the preset position, the feeding device 17 can add contents into the unsealed can body 200 through the top opening of the can body 200. Then, when it is conveyed to the next station, the robot arm 15 transfers the formed can lid 300 to the top of the can body 200, and the can lid 300 is connected to the can body 200 through the sealing assembly 16, completing the integrated production process of can making, filling and sealing. This not only solves the problem that it is difficult to form can packaging with soft film materials (such as aluminum-plastic composite film), but also realizes the automation and integrated production of the entire forming process, effectively improving production efficiency, ensuring product quality, and realizing a high-quality and high-efficiency production mode for can packaging.

[0088] In one optional embodiment of this utility model, such as Figure 1 As shown, the integrated can-making, filling, and sealing equipment also includes a vertically arranged mounting platform 19. The first material conveying mechanism 1 includes a first drive shaft 101 and multiple first transmission rollers 102 mounted on the mounting platform 19. The first drive shaft 101 can be connected to the output shaft of a drive motor, thereby driving the first drive shaft 101 to rotate via the drive motor. The first film material 3, in the form of a strip, is wound around the first drive shaft 101, and the outwardly extending first film material 3 sequentially passes around each first transmission roller 102 and through the first punching mechanism 5. Along the conveying direction of the first film material 3, the first drive shaft 101 can be located upstream of each first transmission roller 102. Each first transmission roller 102 cooperates to tighten the first film material 3, ensuring that the first film material 3 is smoothly and stably conveyed downstream. In this embodiment, the number and position of the first transmission rollers 102 can be arranged according to actual conditions, as long as it ensures that the first film material 3 is tightened and conveyed stably.

[0089] Furthermore, among the multiple first drive rollers 102, at least one first drive roller 102 is a first swing roller. The first swing roller can be used to convey a fixed length of first film material 3 to the first punching mechanism 5 by swinging at a preset angle. The first swing roller plays the role of conveying the first film material 3 to a fixed length, and the swinging action of the first swing roller can also provide power for conveying the first film material 3.

[0090] Furthermore, such as Figure 1 As shown, the integrated can-making, filling, and sealing equipment also includes a receiving roller 22. The receiving roller 22 is set on the mounting platform 19 and can be connected to the output shaft of another drive motor. Along the conveying direction of the first film material 3, the receiving roller 22 is located downstream of the first punching mechanism 5. The receiving roller 22 can be driven to rotate by the drive motor, so that the first film material 3 after being punched by the first punching mechanism 5 can be wrapped around the receiving roller 22, realizing the centralized recycling of the film material.

[0091] In one optional embodiment of this utility model, such as Figure 1 As shown, the second feeding mechanism 2 includes a second drive shaft 201 and multiple second transmission rollers 202 mounted on the mounting platform 19. The second drive shaft 201 can be connected to the output shaft of a second drive motor, thereby driving the second drive shaft 201 to rotate via the drive motor. The second film material 4, in the form of a strip, is wound around the second drive shaft 201, and the outwardly extending second film material 4 sequentially passes around each of the second transmission rollers 202 and extends to the feed inlet of the winding mechanism 8. Along the conveying direction of the second film material 4, the second drive shaft 201 can be located upstream of each of the second transmission rollers 202. Each of the second transmission rollers 202 cooperates to tighten the second film material 4, ensuring that the second film material 4 is smoothly and stably conveyed downstream. In this embodiment, the number and position of the second transmission rollers 202 can be arranged according to actual conditions, as long as it ensures that the second film material 4 is tightened and conveyed stably.

[0092] Furthermore, among the multiple second drive rollers 202, at least one second drive roller 202 is a second swing roller. The second swing roller can be used to convey a fixed length of second film 4 to the winding mechanism 8 by swinging at a preset angle. The second swing roller plays the role of conveying the second film 4 to a fixed length, and the swinging action of the second swing roller can also provide power for the conveying of the second film 4.

[0093] In one optional embodiment of this utility model, such as Figure 1 and Figure 3As shown, the integrated can-making, filling, and sealing equipment also includes a vertically arranged mounting platform 19; the first punching mechanism 5 includes a horizontally arranged mounting plate 501, an upper punching template 503, and a lower punching template 504. The mounting plate 501 is fixed on the mounting platform 19, the lower punching template 504 is located below the mounting plate 501 and the two are connected by multiple connecting columns 507, the upper punching template 503 is located between the mounting plate 501 and the lower punching template 504, and a drive cylinder 502 is provided on the mounting plate 501. The piston rod of the drive cylinder 502 is connected to the upper punching template 503, and the drive cylinder 502 can drive the upper punching template 503 to move away from or closer to the lower punching template 504; when the upper punching template 503 moves downward (i.e., moves closer to the lower punching template 504), the upper punching template 503 and the lower punching template 504 cooperate to form a preset circular can bottom 100 by the first film material 3 located between them. The lower punch template 504 has an openable and closable discharge port (not shown). After the circular can bottom 100 is formed by stamping, the first circular film material 3 formed by stamping can be dropped onto the first conveyor belt 6 below by opening the discharge port, so that the circular can bottom 100 can be transported to the subsequent process by the first conveyor belt 6.

[0094] Furthermore, such as Figure 3 As shown, multiple vertically arranged guide posts 505 are provided between the mounting plate 501 and the lower punch template 504. The upper punch template 503 has multiple guide holes, and the multiple guide posts 505 pass through the corresponding guide holes to allow the upper punch template 503 to move away from or towards the lower punch template 504 along the guide posts 505. The arrangement of multiple guide posts 505 serves to guide the vertical movement of the upper punch template 503.

[0095] Furthermore, such as Figure 3 As shown, multiple springs 506 are provided between the mounting plate 501 and the upper punch template 503. The two ends of the springs 506 are connected to the mounting plate 501 and the upper punch template 503 respectively. After the stamping is completed, the springs 506 can provide restoring force for the upper punch template 503 to reset, so as to ensure that the upper punch template 503 can be smoothly restored to its original position.

[0096] In one optional embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5As shown, the winding mechanism 8 is a circular roll 801 extending horizontally. The inner diameter of the roll 801 is adapted to the outer diameter of the manufactured can body 200. The roll 801 has an inlet and an outlet at both ends. A long strip-shaped slit 401 is located on the top of the roll 801 along its extending direction. A first welding device 9 is mounted on the mounting platform 19 outside the roll 801, and the first welding device 9 is aligned with the slit 401. The second film material 4 can be pre-rolled into a cylindrical shape manually. The second film material 4 is introduced into the roller 801 through the feed port. It enters the roller 801 and is restricted to a pre-rolled cylindrical shape and will not return to its original shape. At this time, it is necessary to ensure that the two adjacent edges of the second film material 4 face upward and are aligned with the gap 401 on the roller 801. Then, when the second film material 4 is pushed forward in the roller 801, the two adjacent edges of the second film material 4 can be welded by the first welding device 9 through the gap 401, thereby forming the cylindrical structure of the can body 200.

[0097] Furthermore, such as Figure 1 , Figures 4 to 6 As shown, two drive rollers are arranged on the mounting platform 19 above the feed inlet of the roll 801. A first reinforcing film 20 and a second reinforcing film 21 are wound onto the two drive rollers, respectively. After the second film 4 enters the roll 801 and is wound into a cylindrical shape, the first reinforcing film 20 and the second reinforcing film 21 can be manually introduced into the roll 801. The first reinforcing film 20 and the second reinforcing film 21 are located on the outer and inner sides of the two opposing edges of the second film 4, respectively. Both the first reinforcing film 20 and the second reinforcing film 21 are along the second film 4... Extending along its length, when the first welding device 9 aligns with the gap 401 on the roll 801 to weld the two adjacent edges of the second film material 4, the first reinforcing film 20 and the second reinforcing film 21 are simultaneously welded to the outer and inner sides of the two adjacent edges of the second film material 4, respectively. This improves the sealing of the welded position of the tank body 200, thereby preventing gaps from forming here and allowing external moisture, impurities, etc. to enter the tank body 200. In other words, the first reinforcing film 20 and the second reinforcing film 21 play a role in strengthening the barrier and can also improve the strength of the tank body 200.

[0098] The first reinforcing film 20 and the second reinforcing film 21 can also be made of aluminum-plastic composite film material.

[0099] Furthermore, such as Figure 5 As shown, the winding mechanism 8 also includes a first vacuum roller 802. The discharge port of the winding drum 801 is sleeved on the outer periphery of the first vacuum roller 802. The formed can body 200 is drawn and shaped by the first vacuum roller 802 to avoid deformation of the can body 200 during welding and transportation.

[0100] In one optional embodiment of this utility model, such as Figure 1 , Figure 7 and Figure 8 As shown, the first transfer mechanism 7 includes an upper mold 701 and a first turntable 702 arranged in a horizontal direction. The upper mold 701 is movably mounted on the mounting platform 19. The first turntable 702 is located below the upper mold 701. The bottom surface of the first turntable 702 is connected to the output shaft of the first motor 703. The first motor 703 is mounted on the mounting platform 19 and can drive the first turntable 702 to rotate circumferentially. Multiple lower molds 704 are evenly and spaced along the circumferential direction on the top surface of the first turntable 702. When the sheet-like can bottom 100 falls onto the top of the upper mold 701, the upper mold 701 is controlled to move downward, thereby pressing the upper mold 701 against the vertically aligned lower molds 704, thus pressing the sheet-like first film material 3 between them to form the can bottom 100.

[0101] The upper mold 701 can be powered by a power source such as an electric cylinder, pneumatic cylinder or hydraulic cylinder to move the upper mold 701 up and down.

[0102] In this embodiment, the interior of the upper mold 701 and / or the interior of the lower mold 704 are equipped with heating elements (such as heating resistors), so that when the upper mold 701 and the lower mold 704 cooperate to press the can bottom 100, hot pressing is achieved, thereby achieving the purpose of hot pressing the sheet-like first film material 3 to form the can bottom 100.

[0103] In one optional embodiment of this utility model, such as Figure 1 and Figure 9 As shown, the second transfer mechanism 11 includes a second turntable 1101 arranged in the horizontal direction. Below the second turntable 1101, there is an electric telescopic rod 1103 extending vertically. The top end of the electric telescopic rod 1103 is connected to the center of the bottom surface of the second turntable 1101, and the bottom end of the electric telescopic rod 1103 is connected to the output shaft of the second motor 1102. The second motor 1102 is fixedly mounted on the mounting platform 19. The second motor 1102 can drive the second turntable 1101 to rotate around its circumference, and the telescopic action of the electric telescopic rod 1103 can drive the second turntable 1101 to adjust its height vertically. The bottom surface of the second turntable 1101 is provided with a plurality of first negative pressure suction cups 1104 spaced apart and evenly arranged along its circumference. The second turntable 1101 is located above the first turntable 702, and the projection of the second turntable 1101 on the horizontal plane overlaps with the projection of the first turntable 702 on the horizontal plane. By controlling the second turntable 1101 to move downward, the first negative pressure suction cups 1104 adsorb the can bottom 100 located on the first turntable 702 and vertically aligned, thereby realizing the transfer of the formed can bottom 100 on the first turntable 702.

[0104] In one optional embodiment of this utility model, such as Figure 1 , Figure 10 and Figure 11 As shown, the welding turntable 12 includes a turntable body 1201. One side of the turntable body 1201 is connected to the output shaft of the third motor 1202. The third motor 1202 is mounted on the mounting platform 19. The third motor 1202 can drive the welding turntable 12 to rotate. Multiple second vacuum rollers 1203 are arranged at intervals along the circumference of the edge of the turntable body 1201. The second vacuum rollers 1203 are adapted to the can body 200. The edge of the turntable body 1201 is directly opposite the discharge port of the roll 801, so that the can body 200 formed by the second punching mechanism 10 can be sequentially fitted onto the outer periphery of the corresponding second vacuum rollers 1203. The negative pressure suction of the second vacuum rollers 1203 can support the can body 200 and prevent it from deforming. In addition, the turntable body 1201 is located below the second turntable 1101, and the axial direction of the turntable body 1201 is perpendicular to the axial direction of the second turntable 1101. By moving the second turntable 1101 down, the bottom of the can 100 adsorbed on the first negative pressure suction cup 1104 is placed at the end of the corresponding second vacuum roller 1203 (corresponding to the bottom of the can body 200 sleeved on the second vacuum roller 1203), so that the bottom of the can 100 and the bottom of the can body 200 located on the second vacuum roller 1203 can be aligned and matched.

[0105] Furthermore, such as Figure 1 and Figure 11 As shown, the second welding device 13 is mounted on the mounting platform 19 and located on one side of the turntable body 1201. The second welding device 13 aligns with the junction of the can bottom 100 and the can body 200 on the second vacuum roller 1203 to weld, forming an unsealed can. During the actual rotation of the welding turntable 12, each second vacuum roller 1203 on the welding turntable 12 needs to pass through four stations sequentially, i.e., as shown in the diagram. Figure 1In the process, each second vacuum roller 1203 on the welding turntable 12 needs to pass through the first loading station, the second loading station, the welding station, and the unloading station in a clockwise direction. At the first loading station, the cut can body 200 is pushed onto the aligned second vacuum roller 1203 by the upstream second conveying mechanism 2. Then, the welding turntable 12 drives the can body 200 to rotate to the second loading station. At the second loading station, the can body 200 is exactly below a first negative pressure suction cup 1104. At this time, the negative pressure adsorption effect of the first negative pressure suction cup 1104 is canceled, and the first negative pressure suction cup 1104 can be automatically sucked up. The attached can bottom 100 is lowered to the bottom of the can body 200; then the welding turntable 12 continues to rotate to the welding station, where the second welding device 13 is aligned with the junction of the can bottom 100 and the can body 200 on the second vacuum roller 1203 and welded; then the welding turntable 12 continues to rotate to the unloading station, where the second vacuum roller 1203 is released from adsorption on the can body 200, and the can body on the second vacuum roller 1203 can fall onto the second conveyor belt 14. At this time, the top opening of the can body 200 is facing upward and the can bottom 100 is facing downward, so that the can lid 300 can be sealed at the top opening of the can body 200 later.

[0106] The second welding device 13 may be, but is not limited to, an ultrasonic welding machine or a laser welding machine.

[0107] In one optional embodiment of this utility model, such as Figure 1 , Figure 12 and Figure 15 As shown, multiple clamping components 23 are evenly and spaced along the conveying direction on the second conveyor belt 14. Each clamping component 23 includes two opposing grippers 2301, which are connected to a movable arm 2304. The movable arm 2304 drives the two grippers 2301 to move away from or towards each other. When the two grippers 2301 move towards each other, a cylindrical clamping space 2302 is formed between them. This clamping space 2302 is adapted to the can body 200 that needs to be clamped. This allows the can body, which has rotated to its lowest point, to be placed between the two grippers 2301 during the rotation of the welding turntable 12. Then, the two grippers 2301 are controlled to clamp the can body, thereby lowering the unsealed can body into the clamping space 2302. This achieves the purpose of stable conveying of the can body and ensuring the stable operation of subsequent filling, nitrogen filling, and sealing.

[0108] In this embodiment, the movable arm 2304 can be connected to a power source such as a hydraulic cylinder or a pneumatic cylinder, which can drive the two movable arms 2304 to move in opposite directions and towards each other, thereby realizing the closing and opening actions of the two grippers 2301. As for how the movable arms 2304 are specifically driven and their connection relationship, no limitation is made here.

[0109] Furthermore, such as Figure 12 As shown, the gripper 2301 has multiple suction holes 2303 on its inner wall within the clamping space 2302. The gripper 2301 has a negative pressure pipe communicating with the suction holes 2303. This negative pressure pipe can be connected to an external vacuum device to create a negative pressure environment within the clamping space 2302. Because the can's material is relatively soft, to ensure it doesn't deform under clamping conditions and for subsequent filling operations, negative pressure suction is needed to support the can and ensure it remains upright under clamping conditions.

[0110] In one optional embodiment of this utility model, such as Figure 1 As shown, the feeding device 17 can be, but is not limited to, a combination scale. A support 24 is provided above the second conveyor belt 14, and the combination scale is fixedly mounted on the support 24. The combination scale can quantitatively weigh the output contents according to the actual filling needs. The second conveyor belt 14 has a feeding station. The discharge port of the combination scale is connected to one end of a discharge pipe (not shown). The other end of the discharge pipe is provided with a filling nozzle that extends to the feeding station. When the can conveyed on the second conveyor belt 14 passes the feeding station, the filling nozzle is positioned exactly above the can and adds a quantitative amount of contents into the can, thereby fulfilling the need to quantitatively add contents to the can conveyed to the feeding station through the filling nozzle. Since the combination scale used in this utility model is a conventional device, its specific structure will not be described here.

[0111] In one optional embodiment of this utility model, such as Figure 1 and Figure 13 As shown, the integrated can-making, filling, and sealing equipment also includes a nitrogen filling device 18. Along the conveying direction of the second conveyor belt 14, the nitrogen filling device 18 is located downstream of the feeding device 17 and upstream of the sealing assembly 16. Thus, after the contents are added to the can body 200 and before sealing, nitrogen gas can be filled into the unsealed can body 200 through the nitrogen filling device 18 to achieve the purpose of nitrogen filling protection.

[0112] Specifically, such as Figure 1 and Figure 13 As shown, the nitrogen filling device 18 includes a liquid nitrogen tank 1801 containing liquid nitrogen. The liquid nitrogen tank 1801 is fixedly mounted on the support 24. A nitrogen filling station is located on the second conveyor belt 14 downstream of the feeding station. The outlet of the liquid nitrogen tank 1801 is connected to one end of the liquid nitrogen pipeline 1802. The other end of the liquid nitrogen pipeline 1802 is provided with a nitrogen filling nozzle 1803, which extends to the nitrogen filling station. Nitrogen gas is filled into the tank that is conveyed to the nitrogen filling station through the nitrogen filling nozzle 1803.

[0113] Furthermore, such as Figure 13As shown, an electric valve 1804 is installed on the liquid nitrogen pipeline 1802. During the nitrogen filling process, the nitrogen filling amount can be preset, and the on / off state of the liquid nitrogen pipeline 1802 can be controlled by the electric valve 1804 to achieve the purpose of quantitative nitrogen filling.

[0114] In one optional embodiment of this utility model, such as Figure 1 and Figure 14 As shown, a robot arm 15 is installed downstream of the nitrogen filling station. The robot arm 15 is mounted on the mounting platform 19. A vibratory feeder 25 is installed on the mounting platform 19 and near the robot arm 15. A vibration motor can be installed at the bottom of the vibratory feeder 25. The vibration motor drives the vibratory feeder 25 to vibrate, so that the multiple pre-formed can lids 300 contained in the vibratory feeder 25 are evenly and flatly laid in the vibratory feeder 25. The moving end of the robot arm 15 has a gripper or a second negative pressure suction cup 1501. Depending on the shape and volume of the can lids 300 to be transferred, the robot arm 15 can be used to transfer the can lids 300 located in the vibratory feeder 25 to the top opening of the can body 200.

[0115] The robotic arm 15 may be, but is not limited to, a four-axis robotic arm, to achieve multi-angle movement.

[0116] In one optional embodiment of this utility model, such as Figure 1 and Figure 15 As shown, a sealing assembly 16 is provided downstream of the robotic arm 15. The sealing assembly 16 includes a third welding device 1601. The third welding device 1601 can be installed on automated equipment such as robotic arms to realize its movable function. When it is necessary to seal the can body 200, the third welding device 1601 moves to the outer periphery of the can body 200 and close to its top, thereby welding the can cover 300 to the top opening of the can body 200 through the third welding device 1601.

[0117] The third welding device 1601 may be, but is not limited to, an ultrasonic welding machine or a laser welding machine.

[0118] Furthermore, such as Figure 1 and Figure 15 As shown, the sealing assembly 16 also includes a movable pressing head 1602. When the can body 200 needs to be sealed, the pressing head 1602 is moved to press the can lid 300 from top to bottom. At this time, the edge of the can lid 300 is closely fitted with the edge of the top opening of the can body 200, which plays a supporting and positioning role for the can lid 300. Then, the third welding device 1601 can be used to weld the edge of the can lid 300 to the edge of the top opening of the can body 200.

[0119] The clamping head 1602 can be powered by a power source, including but not limited to an electric motor, electric cylinder, pneumatic cylinder or hydraulic cylinder, so that the clamping head 1602 can move at least up and down.

[0120] The working process of the integrated can-making, filling, and sealing equipment of this utility model is as follows: the first conveying mechanism 1 and the second conveying mechanism 2 are used to pre-store and supply the first film material 3 and the second film material 4 respectively. The first drive shaft 101 and the first swing roller can cooperate to provide power for conveying the first film material 3 to ensure that the first film material 3 is conveyed downstream. The second drive shaft 201 and the second swing roller can cooperate to provide power for conveying the second film material 4 to ensure that the second film material 4 is conveyed downstream. During the conveying process, the first film material 3 needs to pass through the first punching mechanism 5. The upper punching template 503 and the lower punching template 504 in the first punching mechanism 5 cooperate to punch a preset circular can bottom 100 on the first film material 3 passing between them. The circular can bottom 100 formed by punching falls to the first conveyor belt 6 below and continues to be conveyed downstream. While the first punching mechanism 5 punches the first film material 3, the second film material 4 is conveyed to the winding mechanism 8 on another conveying path. Before the second film material 4 enters the winding mechanism 8, it can be manually rolled into a cylindrical shape and introduced into the winding machine 801 through the feed port. At this time, it is necessary to ensure that the two adjacent edges of the second film material 4 face upward and are aligned with the gap 401 on the winding machine 801. Then, as the second film material 4 is pushed forward in the winding machine 801, the two adjacent edges of the second film material 4 are welded by the first welding device 9 through the gap 401 (or, when the first welding device is set...). In the case of the first reinforcing film 20 and the second reinforcing film 21, the first reinforcing film 20 and the second reinforcing film 21 are respectively welded to the outer and inner sides of the two opposing edges of the second film material 4, thereby forming the cylindrical structure of the can body 200. After that, the welded cylindrical second film material 4 is cut into multiple segments of a preset length during the process of passing through the second punching mechanism 10, that is, multiple can bodies 200 are formed. The can body 200 is conveyed downstream along the roll 801 and is aligned with a second vacuum roller 1203 on the welding turntable 12 that has rotated to the first loading station. The cut can body 200 is sleeved on the aligned second vacuum roller 1203.Simultaneously, the first conveyor belt 6 transports the stamped circular can bottom 100 to the first transfer mechanism 7. After the can bottom 100 falls onto the top of the upper mold 701 of the first transfer mechanism 7, the upper mold 701 is controlled to move downward, so that the upper mold 701 and the vertically aligned lower mold 704 are pressed together, pressing the sheet-like first film material 3 between them to form the can bottom 100. The first transfer mechanism 7 carries the pressed can bottom 100 and rotates until its projection on the horizontal plane overlaps with the projection of the second transfer mechanism 11 on the horizontal plane. At this time, the second transfer mechanism 11 passes through the first negative... The suction cup 1104 adsorbs the vertically aligned can bottom 100 located on the first turntable 702, thereby transferring the adsorbed can bottom 100 to the top of the welding turntable 12 via the rotation of the second transfer mechanism 11. At this time, the welding turntable 12, carrying the can body 200, rotates to the second loading station. The negative pressure adsorption effect of the first negative pressure suction cup 1104 can be canceled, allowing the can bottom 100 adsorbed by the first negative pressure suction cup 1104 to be lowered to the bottom of the can body 200. Then, the welding turntable 12 continues to rotate to the welding station, where the second welding device 13 is aligned with the joint between the can bottom 100 and the can body 200. Welding is performed at the designated location to form an unsealed can. The welding turntable 12 then rotates to the unloading station, which is located above the second conveyor belt 14. The suction of the can body 200 by the second vacuum roller 1203 is released, causing the top opening of the can body 200 to face upwards and the bottom 100 to face downwards, allowing it to slide into the clamping assembly 23 on the second conveyor belt 14. While the clamping assembly 23 holds and positions the can body, it continues to be conveyed downwards along the second conveyor belt 14. When the can body moves to the filling station with the second conveyor belt 14, the feeding device 17 adds a quantitative amount of contents to the can body, followed by nitrogen filling. At the nitrogen filling station, nitrogen is introduced into the tank via the nitrogen filling device 18. After completing the filling and nitrogen filling processes, the robot arm 15, located downstream of the nitrogen filling station, transfers the can lid 300, located in the vibratory feeder 25, to the top opening position of the can body 200. Then, with the pressing head 1602 pressing the can lid 300 tightly against the top opening position of the can body 200, the edge of the can lid 300 is welded to the edge of the top opening position of the can body 200 by the third welding device 1601. This completes the production of the can body, as well as the filling, filling, and sealing processes, thus completing the product manufacturing process. The product can then be removed from the production line for subsequent quality inspection.

[0121] The features and advantages of this integrated can-making, filling, and sealing equipment are:

[0122] This utility model's integrated can-making, filling, and sealing equipment can complete the integrated production process of can making, filling, and sealing. It not only solves the problem that soft film materials (such as aluminum-plastic composite film) are difficult to form into can packaging, but also realizes automated and integrated production throughout the entire forming process, effectively improving production efficiency, ensuring product quality, and realizing a high-quality and high-efficiency production mode for can packaging.
