Description

Technical Field

[0001] This utility model relates to the field of metal processing and manufacturing technology, specifically to a metal can production device. Background Technology

[0002] With the continuous development of the metal can manufacturing equipment industry, various types of metal can forming equipment have been widely used in industrial production. However, these devices still face some challenges in practical applications. For example, current metal can manufacturing equipment typically employs traditional stamping or welding processes, resulting in low levels of automation. When faced with the production of cans with complex structures or high precision requirements, their processing efficiency and stability are limited. This can lead to low production efficiency, product quality fluctuations, and high labor costs.

[0003] Patent document CN116851918B discloses a welding device for automotive fuel tanks. This device uses multiple pressure rollers to automatically clamp and rotate the fuel tanks, and works in conjunction with a laser welding gun to complete the welding operation. This design improves the automation level of welding to some extent, but because its pressure roller positioning method is relatively fixed, it is mainly suitable for fuel tanks of a single specification, and lacks adaptability to metal containers of different diameters or shapes. Furthermore, the device lacks an automatic loading and unloading mechanism, still requiring manual intervention in clamping operations, which may have a certain impact on overall production efficiency.

[0004] Patent document CN107363535B discloses an assembly device for a flange and an oil storage tank assembly. This device includes a feeding mechanism, a clamping mechanism, and a power mechanism, enabling integrated assembly of the flange and the oil storage tank. While this structure improves assembly efficiency, its design is primarily targeted at specific types of oil storage tank assemblies, limiting its versatility. Furthermore, the positioning accuracy during assembly relies on manual adjustment, which may be insufficient for higher precision assembly requirements. In addition, the device lacks intelligent detection capabilities, failing to monitor assembly quality in real time, potentially allowing defective products to flow into subsequent processes, thus increasing the likelihood of rework.

The demands of modern manufacturing for high-quality, high-efficiency, and low-cost production models place higher requirements on existing technologies. Therefore, this utility model aims to provide a metal can production device to improve the applicability, production efficiency, and product quality of the equipment, meeting the actual needs of diverse production scenarios.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides a metal can production apparatus, the structure of which is as follows: Figures 1 to 5 As shown in the figure, the device includes a base frame 1, a sliding bracket 2, a clamping assembly 3, a drive unit 4, a guide rail 5, an adjustment mechanism 6, a transmission shaft 7, a support beam 8, a gear 9, a rack 10, a cylinder body 11, a piston rod 12, a first elastic element 13, a connecting rod 14, a through groove 15, a positioning block 16, an injection pipe 17, a hose 18, a distributor 19, a sealing rod 20, a second elastic element 21, a limiting plate 22, a rubber layer 23, a pull rod 24, a driven gear 25, a chain 26, a power motor 27, a slide 28, a control module 29, and a metal canister 30. The specific embodiments of this device will be described in detail below with reference to the accompanying drawings.

[0028] The base frame 1 serves as the foundation of the entire device, supporting the sliding bracket 2 and other components. The sliding bracket 2 is connected to the base frame 1 via guide rails 5, which are fixed to the two sides of the base frame 1. The bottom of the sliding bracket 2 has a groove 28 that mates with the guide rails 5, allowing the sliding bracket 2 to slide horizontally along the guide rails 5. A pull rod 24 is mounted on the top of the sliding bracket 2, with one end always connected to one end of the clamping assembly 3. The outer wall of the pull rod 24 fits against the top surface of the sliding bracket 2, assisting in the stability of the clamping assembly 3 during movement. A support beam 8 is vertically fixed in the middle of the sliding bracket 2, with both ends extending to the outer side of the sliding bracket 2. A driven gear 25 is mounted on its top, concentrically and coaxially arranged with gear 9 and connected by a chain 26. The chain 26 is driven by a motor 27 located above the sliding bracket 2 to rotate gear 9.

[0029] Clamping assemblies 3 are symmetrically arranged on both sides of the sliding bracket 2. Each clamping assembly 3 is mounted on the sliding bracket 2 via a guide rail 5. Multiple adjustment mechanisms 6 are evenly distributed on the inner end of the clamping assembly 3. The adjustment mechanisms 6 are connected to the drive unit 4 via a transmission shaft 7. The number of adjustment mechanisms 6 corresponds to the number of injection pipes 17 on the inner end of the clamping assembly 3. The outlet of the injection pipe 17 faces downward towards the adjustment mechanism 6. The injection pipe 17 is connected to the cylinder body 11 via a hose 18. A sliding groove 28 is formed on the top of the clamping assembly 3 along its length. The sliding groove 28 is slidably connected to the guide rail 5. A rack 10 is provided on the outer side of the clamping assembly 3. The rack 10 meshes with a gear 9. The rotation of the gear 9 drives the clamping assembly 3 to move longitudinally along the guide rail 5 through the rack 10. Multiple adjustment mechanisms 6 are installed on the inner end of the clamping assembly 3. The adjustment mechanism 6 is connected to the drive unit 4 via a transmission shaft 7. The adjustment range of the adjustment mechanism 6 can be adapted to the diameter or shape of the metal can 30.

[0030] The cylinder body 11 is installed at the middle of the top of both sides of the sliding bracket 2. The opening of the cylinder body 11 faces downward, and a piston rod 12 is installed inside. The top end of the piston rod 12 is fixedly connected to one end of the first elastic member 13, and the other end of the first elastic member 13 is fixedly connected to the inner wall of the cylinder body 11. A connecting rod 14 is installed at the bottom end of the piston rod 12. One end of the connecting rod 14 passes through the through groove 15 at the top of the sliding bracket 2 and is fitted with a positioning block 16. A rubber layer 23 is attached to the outer wall of the connecting rod 14. The rubber layer 23 is arranged along the length of the connecting rod 14 to increase the friction between the connecting rod 14 and the sliding bracket 2 and prevent displacement during sliding. A distributor 19 is also installed on the top of the sliding bracket 2. The distributor 19 is located on one side of the cylinder body 11. The top opening of the distributor 19 is connected to the output end of the drive unit 4 through a hose 18. The bottom opening of the distributor 19 is connected to the positioning block 16 through a hose 18. One side opening of the distributor 19 faces the connecting rod 14. A sealing rod 20 is installed horizontally inside the distributor 19. A second elastic element 21 is sleeved on the outside of the sealing rod 20. The second elastic element 21 is located between one side end face of the distributor 19 and the limiting plate 22. The limiting plate 22 is located outside the connecting rod 14 and is used to limit the movement range of the connecting rod 14.

[0031] The drive unit 4 is connected to the adjustment mechanism 6 via the drive shaft 7. The output end of the drive unit 4 is connected to the top opening of the distributor 19 via the hose 18. The distributor 19 distributes the medium output by the drive unit 4 to the positioning block 16 and the injection pipe 17. The operation of the drive unit 4 is controlled by the control module 29. The control module 29 sends instructions to the drive unit 4 according to the specifications of the metal can 30. The drive unit 4 drives the adjustment mechanism 6 to make adjustments via the drive shaft 7, and at the same time delivers the medium to the distributor 19 via the hose 18. After being distributed by the distributor 19, the medium enters the positioning block 16 and the injection pipe 17 respectively. The injection pipe 17 sprays the medium below the adjustment mechanism 6 to assist the operation of the adjustment mechanism 6.

[0032] In actual operation, the metal can 30 to be processed is first placed between two sets of clamping components 3. The control module 29 sends instructions to the drive unit 4 according to the specifications of the metal can 30. The drive unit 4 drives the adjustment mechanism 6 through the transmission shaft 7 to adjust the inner end of the clamping component 3 to adapt to the diameter or shape of the metal can 30. Subsequently, the power motor 27 starts and drives the driven gear 25 to rotate through the chain 26. The driven gear 25 drives the gear 9 to rotate. The gear 9 drives the clamping component 3 to move longitudinally along the guide rail 5 through the rack 10 until the two sets of clamping components 3 move towards each other and clamp the metal can 30. During this process, the piston rod 12 in the cylinder body 11 pushes the connecting rod 14 to move under the action of the first elastic element 13. The connecting rod 14 drives the positioning block 16 to move through the through groove 15. The positioning block 16 further fixes the position of the metal can 30. The distributor 19 distributes the medium output from the drive unit 4 to the positioning block 16 and the injection pipe 17. The injection pipe 17 sprays the medium below the adjustment mechanism 6, assisting the adjustment mechanism 6 in completing the adaptation operation of the metal can 30. The sealing rod 20 maintains a sealed state under the action of the second elastic element 21, and the limiting plate 22 restricts the movement range of the connecting rod 14 to ensure the accuracy and stability of the operation.

[0033] Through the above structure and operation process, this device can achieve stable fixing and flexible adjustment of metal cylinders 30 of different specifications, meeting the needs of diverse production scenarios.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0035] In actual production, the metal can 30 to be processed is first placed between two sets of clamping components 3. The control module 29 sends instructions to the drive unit 4 according to the specifications of the metal can 30. The drive unit 4 drives the adjustment mechanism 6 to make adjustments via the transmission shaft 7. The adjustment range of the adjustment mechanism 6 is determined by the rotation angle of the transmission shaft 7. Multiple sets of injection pipes 17 at its inner end correspond one-to-one with the adjustment mechanism 6. The outlet of the injection pipes 17 faces downwards from the adjustment mechanism 6 to assist in its operation. The medium is delivered to the distributor 19 through the output end of the drive unit 4. The distributor 19 distributes the medium to the positioning block 16 and the injection pipes 17, thereby ensuring that the adjustment mechanism 6 can quickly adapt to the diameter or shape of the metal can 30.

[0036] Subsequently, the power motor 27 starts, driving the driven gear 25 to rotate via the chain 26. The driven gear 25 is concentrically and coaxially arranged with the gear 9, and the rotation of the gear 9 drives the clamping assembly 3 to move longitudinally along the guide rail 5 via the rack 10. During this process, a pull rod 24 is installed on the top of the sliding bracket 2, one end of which is always connected to one end of the clamping assembly 3, and its outer wall is in contact with the top surface of the sliding bracket 2 to ensure the stability of the clamping assembly 3 during movement. A sliding groove 28 is formed on the top of the clamping assembly 3 along its length, and the sliding groove 28 is slidably connected to the guide rail 5, further enhancing the smoothness of the movement of the clamping assembly 3.

[0037] When the two sets of clamping assemblies 3 move towards each other, the piston rod 12 inside the cylinder body 11 pushes the connecting rod 14 to move under the action of the first elastic element 13. A rubber layer 23 is attached to the outer wall of the connecting rod 14, arranged along the length of the connecting rod 14, increasing the friction between the connecting rod 14 and the sliding bracket 2, preventing displacement during sliding. A positioning block 16 is installed at one end of the connecting rod 14 after passing through the through groove 15 at the top of the sliding bracket 2, further fixing the position of the metal can 30. The top opening of the distributor 19 is connected to the output end of the drive unit 4 via a hose 18, and the bottom opening of the distributor 19 is connected to the positioning block 16 via a hose 18. One side opening of the distributor 19 faces the connecting rod 14, and a sealing rod 20 is installed laterally inside it. A second elastic element 21 is sleeved on the outside of the sealing rod 20. The second elastic element 21 is located between one end face of the diverter 19 and the limiting plate 22. The limiting plate 22 is located on the outside of the connecting rod 14 and is used to limit the range of movement of the connecting rod 14, thereby ensuring the accuracy and stability of the operation.

[0038] After the clamping assembly 3 clamps the metal can 30, the injection pipe 17 sprays the medium below the adjusting mechanism 6, which then completes the adaptation operation of the metal can 30. During this process, the sealing rod 20 maintains a sealing state under the action of the second elastic element 21 to prevent medium leakage, while the limiting plate 22 restricts the movement range of the connecting rod 14 to ensure the reliability of the entire operation. Through the above steps, the device achieves stable fixing and flexible adjustment of metal cans 30 of different specifications.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
