Technical Field

[0001] This invention relates to an aluminum plate rolling equipment, belonging to the field of aluminum plate rolling technology. Background Technology

[0002] In the aluminum sheet processing industry, rolling is one of the key process steps used to press aluminum sheets into the required thickness and shape. Traditional aluminum sheet rolling equipment typically has a fixed rolling channel, and the size of its roll opening cannot be flexibly adjusted, which limits the equipment's ability to process aluminum sheets of different sizes. Furthermore, traditional drive mechanisms often require readjustment or replacement after roll position adjustments, increasing production costs and maintenance difficulty. Therefore, this invention provides an aluminum sheet rolling device that solves the above problems. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an aluminum plate rolling equipment that can solve the problem of the inability to adjust the position of the rolls.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum plate rolling equipment, comprising a rolling channel for rolling aluminum plates, wherein the rolling channel includes: The feed port is used to guide the aluminum sheet into the rolling channel. During the process of the aluminum sheet entering the channel, the feed port can apply a compressive deformation force to the aluminum sheet. The discharge port is the outlet of the aluminum sheet that is discharged from the rolling channel. During the process of the aluminum sheet being discharged from the channel, the discharge port can apply a compressive deformation force to the aluminum sheet. The opening of the feed inlet is larger than the opening of the discharge outlet. The opening sizes of both the feed inlet and the discharge outlet are adjustable, and the changes in the opening sizes of the feed inlet and the discharge outlet are inversely proportional.

[0005] Preferably, the feed inlet is formed by the distance between two first rollers, and the distance between the two first rollers is the size of the feed inlet opening; the discharge outlet is formed by the distance between two second rollers, and the distance between the two second rollers is the size of the discharge outlet opening.

[0006] Preferably, the rolling equipment further includes two symmetrically arranged support bodies, each support body including a rotating shaft and two legs. The support body is rotatable around the rotating shaft, and the center of the rotating shaft and the two legs forms a triangle. The line connecting the two rotating shafts is perpendicular to the extension direction of the rolling channel, and the two legs are respectively arranged on both sides of the rotating shaft. The first roll and the second roll are respectively rotatably installed at the positions of the two legs.

[0007] Preferably, the rolling equipment further includes: The first gear is rotatably mounted on the support body, and each first roll and second roll is coaxially connected to a first gear; Each support body has a rotatable gear ring, the axis of the gear ring is coaxial with the axis of the rotating shaft, and the gear ring meshes with the first gear on the same support body.

[0008] Preferably, each support leg of the support body is provided with two fixing rings, the first or second roller is rotatably mounted on the fixing rings, and the first gear is fixedly connected to the roller via a coupling shaft.

[0009] Preferably, a drive tooth is fixed on the support body, and a second gear that meshes with the drive tooth is rotatably installed inside the rolling equipment.

[0010] Preferably, the inner ring wall of the gear ring is provided with teeth, and a third gear that meshes with the teeth is rotatably installed inside the rolling equipment.

[0011] Preferably, the rolling equipment has a limiting groove inside, and the first roll and the second roll can move inside the limiting groove.

[0012] Preferably, both the first roll and the second roll are provided with annular protrusions.

[0013] Beneficial effects Compared with existing technologies, this invention incorporates a rolling channel in the aluminum sheet rolling equipment, where both the inlet and outlet are equipped with the function of applying compressive deformation force to the aluminum sheet. This design allows the aluminum sheet to be subjected to compressive deformation in layers during the rolling process, thereby improving rolling efficiency and effectiveness. The sizes of both the inlet and outlet are adjustable, giving this rolling equipment adaptability and easily meeting the processing needs of different types of aluminum sheets.

[0014] Regarding the drive mechanism, this invention utilizes a gear ring to drive a first gear, which in turn drives the rotation of the roll. This design ensures that the roll can still be stably driven by the gear ring even after its position is adjusted. This means that we do not need to replace or adjust the drive mechanism when adjusting the roll position, saving production and maintenance costs. Attached Figure Description

[0021] The present invention is illustrated below with specific embodiments, but these are not intended to limit the invention.

[0022] Example 1 like Figure 1 As shown in this embodiment, an aluminum plate rolling device includes a rolling channel for applying rolling action to the aluminum plate. The rolling channel is a critical path that the aluminum plate must pass through during the rolling process. As the aluminum plate travels along this channel, it is subjected to continuous forces from the rolls in a specific rolling zone, thereby achieving the rolling process. This process includes plastic deformation, thickness adjustment, and surface leveling of the aluminum plate. Commercially available rolling equipment is generally equipped with such a rolling channel to ensure that the aluminum plate can be rolled in a stable and continuous manner, meeting the production line's requirements for the size, shape, and quality of the aluminum plate. In short, the rolling channel is the core component of the rolling equipment that realizes the aluminum plate rolling function; its design and performance directly affect the rolling effect and production efficiency of the aluminum plate.

[0023] The rolling channel includes an inlet and an outlet. The inlet guides the aluminum sheet into the rolling channel, applying a compressive force during entry. This not only helps maintain the stability of the aluminum sheet during subsequent rolling but also pre-adjusts its shape to some extent, laying a good foundation for later rolling operations. In short, the inlet plays a crucial guiding and pre-treatment role in aluminum sheet rolling, ensuring the sheet enters the rolling channel in a better condition, thus improving the efficiency and quality of the entire rolling process. The outlet is where the aluminum sheet exits the rolling channel. Applying a compressive force during exit, the outlet further compresses and deforms the sheet as it passes through and leaves the rolling channel. This step ensures the aluminum sheet achieves the expected rolling effect and quality requirements upon exiting the rolling equipment, meeting the needs of subsequent processing or use. The discharge port not only provides a channel for the aluminum sheet to be discharged, but also continues to apply a compressive and deforming force to the aluminum sheet during the discharge process, ensuring the integrity and continuity of the aluminum sheet rolling process.

[0024] The inlet opening is larger than the outlet opening, and both the inlet and outlet openings are adjustable. Furthermore, the openings of the inlet and outlet are inversely proportional. Specifically, through a corresponding adjustment mechanism, the opening degree of the inlet and outlet can be flexibly adjusted to adapt to the rolling requirements of aluminum sheets of different thicknesses and widths. It is worth noting that the openings of the inlet and outlet exhibit an inverse relationship; that is, when the inlet opening increases, the outlet opening decreases accordingly, and vice versa.

[0025] Example 2 like Figure 1 , Figure 3 and Figure 4 As shown, based on Embodiment 1, this embodiment provides the structure of the inlet and outlet, as detailed below: The feed inlet is formed by the distance between the two first rolls 1, and the distance between the two first rolls 1 determines the size of the feed inlet opening. The discharge outlet is formed by the distance between the two second rolls 2, and the distance between the two second rolls 2 determines the size of the discharge outlet opening. Changing the distance between the two first rolls 1 adjusts the size of the feed inlet opening. When the distance between the two first rolls 1 increases, the feed inlet opening becomes larger, and vice versa. Similarly, when the distance between the two second rolls 2 decreases, the discharge outlet opening becomes larger, and vice versa. The rolling equipment is equipped with a limiting groove 9 inside, and the first rolls 1 and the second rolls 2 can move inside the limiting groove 9. The limiting groove 9 is an arc groove, which can limit the rotation angle of the first rolls 1 and the second rolls 2, preventing the distance between the two first rolls 1 from being too large or too small. If the distance is too large, it will be impossible to apply pressure and deformation to the aluminum plate.

[0026] Both the first roll 1 and the second roll 2 are provided with annular protrusions. The annular protrusions can be adapted to aluminum plates of different shapes. The shape of the annular protrusions can be adjusted according to the shape of the aluminum plate to process aluminum plates of different shapes.

[0027] Example 3 like Figure 1 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides a roller mounting structure, as detailed below: The rolling equipment also includes two symmetrically arranged support bodies 3, which are distributed vertically with respect to the center line of the rolling channel. The rolling channel is arranged between the two support bodies 3. Each support body 3 includes a rotating shaft 4 and two legs. The support body 3 can rotate around the rotating shaft 4. This design is to adjust the distance between the rolls. The center of the rotating shaft 4 and the two legs form a triangle, which provides stability and strength to the support body 3. The line connecting the two rotating shafts 4 is perpendicular to the extension direction of the rolling channel, and the two legs are respectively arranged on both sides of the rotating shaft 4. The first roll 1 and the second roll 2 are rotatably mounted on the two legs. Since the opening of the feed port is larger than the opening of the discharge port, it is necessary to ensure that the distance between the two first rolls 1 is always greater than the distance between the two second rolls 2. That is, the two legs on the same support body 3 are never on the same horizontal plane.

[0028] Example 4 like Figures 1-5 As shown, based on Embodiments 1-3, this embodiment provides a driving structure for the rolling mill, as detailed below: The rolling equipment also includes a first gear 5 and a gear ring 7. The first gear 5 is rotatably mounted on the support body 3. Each first roll 1 and second roll 2 is coaxially connected to a first gear 5. The first gear 5 can follow the first roll 1 and the second roll 2 to rotate around the rotating shaft 4 inside the rolling equipment. Each support body 3 is correspondingly provided with a rotatable gear ring 7. The gear ring 7 will rotate around its rotating shaft 4. The axis of the gear ring 7 is coaxial with the axis of the rotating shaft 4. The gear ring 7 and the first gear 5 on the same support body 3 are meshed with each other. The first gear 5 rotates around the rotating shaft 4. The axis of the rotating shaft 4 coincides with the axis of the gear ring 7. That is, the first gear 5 will rotate around the axis of the gear ring 7. Therefore, the rotation of the first gear 5 will not affect the meshing with the gear ring 7. The rotation of the gear ring 7 can drive the two first gears 5 to rotate simultaneously.

[0029] Each support leg of the support body 3 is provided with two fixing rings 8. The first roller 1 or the second roller 2 is rotatably mounted on the fixing ring 8. The first gear 5 is fixedly connected to the roller through a connecting shaft. The first roller 1 and the second roller 2 are rotatably mounted on the two side support legs respectively. The first roller 1 and the second roller 2 are rotatably mounted on the two support legs respectively.

[0030] A drive gear 6 is fixed on the support body 3. A second gear, meshing with the drive gear 6, is rotatably mounted inside the rolling mill. Teeth are provided on the inner ring wall of the gear ring 7, and a third gear, meshing with the teeth, is rotatably mounted inside the rolling mill. Multiple motors are installed inside the rolling mill, specifically for driving the second and third gears. When the second gear starts rotating, it drives the support body 3 to rotate flexibly around the rotating shaft 4, thereby achieving precise adjustment of the inlet and outlet sizes. This design cleverly realizes a linkage mechanism between the inlet and outlet; that is, when the inlet expands, the outlet correspondingly shrinks, ensuring balanced material flow during the rolling process.

[0031] In addition, the rolling mill is equipped with a special circular groove for the rotation of the gear ring 7. When the third gear rotates, it guides the gear ring 7 to rotate smoothly around its central axis within the groove. The rotation of the gear ring 7 further drives the rotation of the first roll 1 and the second roll 2 via the first gear 5. As the first roll 1 and the second roll 2 rotate, they exert a strong pushing force on the aluminum plate, ensuring that the aluminum plate can pass through the rolling zone smoothly and continuously to complete the required processing.

[0032] Working principle: The aluminum sheet first enters the rolling channel through a wide inlet and then exits through the outlet. As the aluminum sheet passes through the inlet, the symmetrically arranged first rolls 1 apply a compressive force to it, ensuring that the aluminum sheet receives proper pretreatment before entering the rolling channel. Simultaneously, as the aluminum sheet is about to leave the rolling channel and pass through the outlet, the second rolls 2 also apply a compressive force to it, completing the final rolling process.

[0033] Because the feed inlet has a larger opening than the discharge outlet, it plays a crucial guiding and pre-treatment role in the aluminum sheet rolling process, enabling the aluminum sheet to enter the rolling channel in a flatter and more stable state, thereby improving the efficiency and quality of the entire rolling process.

[0034] It is worth mentioning that by adjusting the rotation angle of the support body 3, we can flexibly adjust the opening size of the inlet and outlet. This adjustment is linear; the opening will continuously increase or decrease, thus facilitating changes in the size of the aluminum plate according to different processing requirements. More importantly, regardless of the change in opening size, the gear ring 7 can always stably drive the first roll 1 and the second roll 2 to rotate, demonstrating its excellent adaptability and stability.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention without departing from the spirit and scope of the present invention. Any modifications or partial substitutions should be covered within the scope of the claims of the present invention.
