[0002] With the rapid development of modern industrial production, the demand for various containers, especially tanks, continues to increase. Tanks are widely used, covering a wide range of fields, from food and beverages to chemicals and pharmaceuticals. To meet the needs of different industries, the appearance and structural design of tanks are becoming increasingly diverse.

[0003] The curling process of can edges is crucial in can production, not only enhancing the strength and sealing of the cans but also improving their overall aesthetics. However, existing curling machine technology primarily focuses on curling the edges of round cylindrical containers, and often struggles to meet the requirements for curling the edges of irregularly shaped cans, especially those with unique shapes and sizes.

[0004] The existing curling machine technology has the following main shortcomings when processing the curling of the edges of special-shaped cans:

[0005] 1. Limited scope of application. Most common curling machines on the market can only process the edges of round cylindrical containers and cannot effectively curl the edges of special-shaped cans.

[0006] 2. Complex structure and high cost. There are only a few curling machines that can process the edges of special-shaped cans. Their structure is complex, the production cost is high, and the price is expensive, making it difficult to popularize and apply them in actual production.

[0007] 3. The curling effect is not good. The existing special-shaped curling mechanism often cannot ensure the flatness, beauty and firmness of the curling effect during the curling process, and it is difficult to meet the needs of high-quality curling.

[0008] Therefore, there is an urgent need for a new type of special-shaped crimping device to meet the crimping operation of special-shaped cans. Summary of the Invention

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a curling device includes an outer shell component 1, an inner shaft component 2, a curling component 4 and a contour wheel 3. The inner shaft component 2 is fixedly arranged, and the outer shell component 1 and the inner shaft component 2 are connected by a bearing 15. The inner ring of the bearing 15 is sleeved on the inner shaft component 2, and the outer ring of the bearing 15 abuts against the outer shell component 1. The outer shell component 1 rotates with the inner shaft component 2 as the axis. A movable track 11 is provided on the outer shell component 1, and the movable track 11 extends outward from the inner shaft component 2. Preferably, the movable track 11 extends along a straight line. The curling component 4 is installed in the movable track 11, and the curling component 4 can slide in the movable track 11. The contour wheel 3 is fixedly installed on the inner shaft component 2, and the curling component 4 abuts against the outer edge of the contour wheel 3. The shape of the outer edge of the contour wheel 3 is the same as the shape of the edge to be curled of the product C.

[0031] During the curling operation, the shell component 1 rotates, driving the curling component 4 to rotate accordingly. At the same time, the curling component 4 abuts against the outer edge of the profiling wheel 3. As the curve of the outer edge of the profiling wheel 3 changes, the curling component 4 moves within the moving track 11, so that the path traveled by the curling component 4 is the same as the outer edge of the profiling wheel 3, thereby realizing the curling of the edge of the product C.

[0032] The contour wheel 3 is shaped identically to the edge of product C to be curled, ensuring that the curling assembly 4 always closely follows the edge of product C, achieving a precise curling effect. The curling assembly 4 moves within the track 11, following the curve of the outer edge of the contour wheel 3 to ensure that the curling path is completely consistent with the edge of product C, avoiding deviation or unevenness.

[0033] By replacing different profiling wheels 3, the device can adapt to product C edges of various shapes and sizes, such as round, square, oval, etc., and has high flexibility.

[0034] The hemming assembly 4 slides in the moving track 11, eliminating the need for a complex mechanical transmission structure, thereby improving hemming efficiency. The rotation of the housing assembly 1 drives the hemming assembly 4, thereby achieving continuous hemming and improving production efficiency.

[0035] In the present application, curling is achieved by moving the roller assembly while fixing the product C. When the curling assembly 4 rotates, the curling path can be accurately controlled to ensure the uniformity and consistency of the curling effect.

[0036] If product C rotates while the rolling assembly is fixed, it is difficult to control the rotation of product C. At least product C needs to be stably clamped. Unstable clamping will also affect the curling effect. In addition, product C must be rotated at a uniform speed and the edge curling must be achieved. This process is relatively difficult to achieve. Product C itself may have deviations or jitters, making it difficult to ensure precise control of the curling path, resulting in uneven curling effects or defects.

[0037] Furthermore, if product C rotates while the rolling assembly is fixed, product C will be subjected to a clamping force, a force that rotates product C, and a force that curls the edges. The additional forces on product C can easily cause deformation, and deformation may occur at the fixed position, at the position where the rotational force is applied to product C, at the curling position, or at all of the above positions, affecting the curling effect and even damaging the curling machine.

[0038] The rotation of the curling assembly 4 of the present invention can reduce the deformation of the product C and ensure the perfect curling effect. In addition, since the product C is fixed, only the rotation of the curling assembly 4 needs to be controlled, which makes it easier to achieve precise control.

[0039] Furthermore, since product C is fixed, operators can more easily observe the status of product C and then perform operation and maintenance, thereby improving work efficiency and safety.

[0040] In a preferred embodiment, the curling assembly 4 slides in the moving track 11 in such a manner that the curling assembly 4 includes a mounting bracket 44 and a cover plate 45. A portion of the mounting bracket 44 passes through the moving track 11, and the portion of the mounting bracket 44 that passes through the moving track 11 can slide along the moving track 11. The cover plate 45 is mounted on the mounting bracket 44, and the width of the cover plate 45 is greater than the width of the moving track 11. Figure 1The cover plate 45 is provided above the mounting bracket 44 to prevent the mounting bracket 44 from sliding off the moving track 11. Preferably, the mounting bracket 44 forms a lower end portion below the moving track 11, and the width of the lower end portion is also greater than the width of the moving track 11. The lower end portion and the cover plate 45 are provided on the upper and lower sides of the moving track 11, so that the movement of the hemming assembly 4 in the moving track 11 is more stable.

[0041] The width of the cover 45 is greater than the width of the moving track 11, and the width of the lower end of the mounting bracket 44 is also greater than the width of the moving track 11, which increases the stability of the curling component 4 in the moving track 11, prevents the component from tilting or rolling during movement, and further improves the curling accuracy.

[0042] The cover plate 45 and the lower end portion are respectively located on the upper and lower sides of the movable track 11, forming an upper and lower clamping structure, which enhances the lateral force resistance of the curling component 4, prevents displacement due to lateral force during the curling process, and improves the stability and reliability of the curling process.

[0043] Since the curling assembly 4 slides more stably in the movable track 11, the friction between the assembly and the track is reduced, the degree of wear is reduced, and the service life of the equipment is extended. At the same time, the friction noise during the sliding process is reduced, and the working environment is improved.

[0044] And this structural design is simple, easy to process and assemble, and reduces production cost. Because the component structure is simple, maintenance is convenient, and only needs to clean the moving track 11 and lubricate the sliding parts regularly, thus reducing maintenance cost.

[0045] Specifically, Figure 1 As shown, the curling assembly 4 includes a curling wheel 41 for curling. The curling wheel 41 is provided with a curling groove 411. The edge of the product C is formed along the curling groove 411. The curling groove 411 is arc-shaped so that the edge of the product C passes through the curling groove 411. Figure 2 The outward curling state is formed as Figure 3 The state shown is rolled outward into an arc. It is worth noting that Figure 2 and Figure 3 Both are schematic diagrams of the edge of product C. The left side of the figure is the inside of product C, and the right side of the figure is the outside of product C, that is, the edge of product C is curled toward the outside.

[0046] Adjusting the position of the curling component 4 relative to the product C can also achieve the curling of the product C inward. Of course, the edge of the product C also needs to be slightly curled inward. The curling groove 411 is facing the inside of the product C to achieve the curling of the product C inward.

[0047] Furthermore, one end of the inner shaft assembly 2 has a guide seat 13, which is used to press and fix the product C. At the same time, for the disc-shaped product C, the side of the product C is arranged along the side of the guide seat 13, and the guide seat 13 provides support for the product C. The bottom of the guide seat 13 is consistent with the bottom shape of the product C, and the side of the guide seat 13 corresponds to the side of the product C. During the curling process, the side of the guide seat 13 provides effective support for the edge of the product C.

[0048] In a preferred embodiment, the shape of the bottom surface of product C is consistent with the shape of the edge, and the side is a smooth plane. At this time, the shapes of product C, the contour wheel 3 and the guide seat 13 are all the same. Preferably, when curling is required to the outside of product C, the curling groove 411 is arranged on the outside of the guide seat 13.

[0049] The curling groove 411 is designed to be arc-shaped, and the product C can be curled inward or outward by adjusting the position of the curling component 4 relative to the product C. This greatly improves the applicability of the curling component 4 and can be used for different types of products C.

[0050] When the product C needs to be curled outward, the curling groove 411 is set on the outside of the guide seat 13, which can effectively guide the edge of the product C to be curled along the curling groove 411, ensuring the accuracy and consistency of the curling effect.

[0051] The operator of the device only needs to adjust the position of the curling component 4 to easily achieve curling to the inside or outside without replacing parts, and the operation is simple and convenient.

[0052] The guide base 13 provides support for the product C, effectively fixing the product C in place and preventing it from moving or deforming during the hemming process, thereby improving hemming efficiency. The side edges of the guide base 13 provide support for the edges of the product C, effectively preventing it from twisting or deforming during the hemming process, ensuring the quality of the hemming effect.

[0053] The arc-shaped design of the curling groove 411 can change the edge of the product C from a slightly curled state to an arc-shaped state after passing through the curling groove 411, thereby improving the quality of the curling effect.

[0054] For the disc-shaped product C, the side edges of the guide seat 13 form effective support for the edges of the product C, which can effectively prevent the product C from moving or deforming during the curling process, thereby improving the quality of the curling effect.

[0055] Further, if Figure 1As shown, the hemming wheel 41 is tilted relative to the guide seat 13, and the hemming groove 411 is tilted relative to the bottom of the guide seat 13. The tilt of the hemming wheel 41 relative to the guide seat 13 makes the hemming process smoother, making it easier for the edge of the product C to bend along the hemming groove 411, reducing resistance during the hemming process and minimizing damage to the product C. Furthermore, the hemming angle can be adjusted according to actual needs, achieving a more precise hemming effect and meeting the hemming requirements of different products C. The tilted hemming groove 411 design creates a more natural curvature on the edge of the hemmed product C, enhancing the overall aesthetics of the product C.

[0056] The tilted hemming wheel 41 and hemming groove 411 design stabilizes the hemming process, reduces deviation or deformation of the product C during the hemming process, and enhances the reliability of the hemming process. The tilted design effectively disperses the pressure during the hemming process, reduces wear on equipment components, and improves the durability of the equipment.

[0057] In a preferred embodiment, the hemming wheel 41 has a side end surface that is flush with the upper end surface of the guide seat 13 and is positioned above the guide seat 13. The side end surface is positioned so that it is flush with the upper end surface of the guide seat 13. This alignment provides the optimal tilt angle for the hemming wheel 41, facilitating installation and positioning by the user. Preferably, multiple side end surfaces can be provided on the hemming wheel 41 to facilitate the determination of multiple tilt angles for varying degrees of hemming.

[0058] In addition, the side end surface of the curling wheel 41 is located above the guide seat 13. During the curling process, when shaking or deformation occurs, the upper end surface of the guide seat 13 can also support the curling wheel 41 to avoid damage to the curling device.

[0059] The side end surface of the hemming wheel 41 is flush with the upper end surface of the guide seat 13, simplifying the installation process of the hemming wheel 41. This eliminates the need for complex adjustments and allows operators to easily complete installation, improving work efficiency. The relative position of the hemming wheel 41 and the guide seat 13 is fixed, simplifying the commissioning process of the hemming device. Operators can quickly adjust the hemming parameters, saving commissioning time.

[0060] Furthermore, two symmetrical curling grooves 411 are provided on either side of the curling wheel 41. A gap is provided between the two curling grooves 411, allowing the curling grooves 411 on one side of the curling wheel 41 to be reversed for use after wear. Having curling grooves 411 on both sides of the curling wheel 41 allows for double-sided use, effectively extending the service life of the curling wheel 41, reducing the frequency of replacement of the curling wheel 41, and lowering production costs.

[0061] Preferably, the hemming wheel 41 itself is asymmetrical on both sides, and hemming grooves 411 are provided on both sides to meet the hemming requirements of products C of different shapes and sizes, thereby enhancing the flexibility of the equipment. Different hemming grooves 411 can be selected according to actual conditions to meet different hemming requirements, thereby improving the adaptability of the equipment.

[0062] like Figure 1 The hemming assembly 4 further includes a movable bearing 42. The movable bearing 42 and the hemming wheel 41 are fixedly mounted on a mounting bracket 44. The movable bearing 42 can roll against the contour wheel 3. In this way, the movable bearing 42 rolls against the outer edge of the contour wheel 3, and the hemming wheel 41 is also driven.

[0063] Preferably, the movable bearing 42 adopts a heavy-load bearing 15 .

[0064] Furthermore, the hemming assembly 4 also includes a pressure device 43, which is mounted on the housing assembly 1 and drives the movable bearing 42 against the contour wheel 3. Preferably, the pressure device 43 is a spring, one end of which is mounted on the housing assembly 1 and the other end of which is connected to the movable bearing 42. The spring applies an elastic force to the movable bearing 42, ensuring that the movable bearing 42 always conforms to the contour wheel 3 during the hemming process, and the spring elastically deforms when the hemming assembly 4 moves. More preferably, the pressure device 43 is a hydraulic lever or cylinder, which uses hydraulic or pneumatic means to apply pressure to the movable bearing 42 against the contour wheel 3, and the hydraulic lever or cylinder follows the piston motion when the hemming assembly 4 moves.

[0065] Furthermore, the housing assembly 1 has an outwardly protruding flange 12 , and the movable track 11 is provided on the flange 12 .

[0066] The housing assembly 1 is provided with a plurality of crimping assemblies 4, which are arranged in a ring-shaped array around the axis of the housing assembly 1. The ring-shaped arrangement of the crimping assemblies 4 can more evenly distribute the force applied to the housing assembly 1 and prevent deformation of the product C.

[0067] Preferably, the housing assembly 1 is connected to a motor, and the motor drives the housing assembly 1 to rotate; more preferably, the housing assembly 1 is provided with a pulley 14 for transmitting power to an external power assembly, and the external power assembly can be a motor.

[0068] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
