Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to an automatic polishing device for mirror-finish aluminum plates. Background Technology

[0002] Mirror-finish aluminum has a wide range of applications. It is widely used in lighting reflectors and lamp decorations, solar thermal reflective materials, interior building decoration, exterior wall decoration, household appliance panels, electronic product casings, furniture and kitchens, automotive interior and exterior trim, signs, logos, bags, jewelry boxes, and other fields.

[0003] After aluminum sheets are rolled, they need to undergo grinding and polishing processes to achieve a mirror-like finish. The surface roughness is reduced during the grinding stage, and then polishing is performed using polishing rollers. Existing polishing rollers are usually cylindrical or disc-shaped, with a small contact area with the aluminum material. Therefore, the aluminum sheet needs to move at a low speed to allow sufficient polishing time to achieve a mirror-like finish on the aluminum surface, which results in a lack of production efficiency. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides an automatic polishing device for mirror-finish aluminum plates. This embodiment aims to provide a device for polishing mirror-finish aluminum surfaces, increasing the contact area between the polishing mechanism and the aluminum material, improving polishing efficiency, and thus achieving a better polishing effect even when the aluminum material moves at a relatively high speed, thereby improving production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic polishing device for mirror aluminum plates includes a frame. The lower part of the frame is provided with a carrying and conveying mechanism. The upper part of the frame is provided with a coarse grinding mechanism, a fine grinding mechanism and a polishing mechanism in sequence along the transmission direction of the carrying and conveying mechanism. The coarse grinding mechanism, fine grinding mechanism and polishing mechanism are respectively controlled by a lifting mechanism to rise or fall on the frame. The frame is provided with a mechanism to guide the coarse grinding mechanism, fine grinding mechanism and polishing mechanism.

[0007] The polishing mechanism includes a housing, on which a drive roller and multiple support rollers are rotatably connected. The input shaft of the drive roller passes through the housing and is connected to a drive motor. A polishing ring in a tensioned state is connected to the drive roller and multiple support rollers. After the lifting mechanism descends, the multiple support rollers press the polishing ring onto the material to be processed. The polishing ring is driven by the drive roller to rotate outside the drive roller and multiple support rollers and performs polishing.

[0008] Furthermore, the multiple support rollers are on the same horizontal plane, and the drive roller is located above the multiple support rollers.

[0009] Furthermore, multiple support rollers are connected to the same arc-shaped surface via an arc-shaped tensioner, and the drive roller is located above the multiple support rollers.

[0010] Furthermore, the arc-shaped tensioner is composed of at least one arc-shaped metal plate, and multiple support rollers are rotatably connected to the arc-shaped tensioner at equal intervals. The support rollers located on both sides are connected to the drive rollers via connecting rods with bearings at both ends. The housing is provided with a guide mechanism to guide the support roller located in the middle.

[0011] Furthermore, the guiding mechanism is a vertically arranged elongated hole or groove, and the two ends of the middle support roller among the multiple support rollers are respectively located in the guiding mechanism and slide along the guiding mechanism.

[0012] Furthermore, there is a gap between the plurality of support rollers.

[0013] Furthermore, the polishing ring includes a flexible ring structure and a polishing connection portion connected to the ring structure.

[0014] Furthermore, the polishing connection is connected to the outside of the ring structure via connectors, and the connectors are offset from each other.

[0015] Furthermore, the drive roller is evenly distributed with spikes that can penetrate into the ring structure.

[0016] The beneficial effects of this utility model embodiment are as follows:

[0017] 1. This utility model has surface contact with the material being polished, resulting in a larger polishing area, allowing the material to move quickly and improving polishing efficiency.

[0018] 2. This utility model is equipped with an arc-shaped tensioner, which can adjust the pressure and contact area on the polished material as needed, making it more versatile.

[0019] 3. The polishing belt of this utility model is connected to the polishing connection part by a connector, and the connectors are staggered with each other, which does not affect the polishing effect and facilitates the quick replacement of the polishing connection part.

[0029] The preferred embodiments of this utility model are described below using the processing of mirror-finished aluminum sheet and strip as an example, with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model. Example

[0030] See Figure 1 and Figure 2As shown in the figure, this utility model discloses an automatic polishing device for mirror aluminum plates, including a frame 1. The frame 1 has an "n"-shaped frame with an internal grinding and polishing space. A carrying and conveying mechanism 2 penetrating the grinding and polishing space is provided at the lower part of the frame 1. A coarse grinding mechanism 3, a fine grinding mechanism 4, and a polishing mechanism 5 are sequentially arranged at the upper part of the frame 1 along the transmission direction of the carrying and conveying mechanism 2. The coarse grinding mechanism 3 and the fine grinding mechanism 4 have the same structure as the polishing mechanism 5, or existing coarse grinding and fine grinding mechanisms can be used. Multiple lifting mechanisms 6 are connected to the top of the frame 1. The multiple lifting mechanisms 6 are connected to the coarse grinding mechanism 3... The fine grinding mechanism 4 and the polishing mechanism 5 are in one-to-one correspondence. The lifting mechanism 6 is a hydraulic telescopic rod or an electric telescopic rod. The output ends of multiple lifting mechanisms 6 pass through the frame 1 and extend into the upper part of the frame 1, and are respectively connected to the top of the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5. The lifting mechanism 6 controls the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5 to rise or fall within the frame 1. The frame 1 is provided with a mechanism to guide the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5, so that the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5 can only rise or fall in the vertical direction and cannot deviate in the horizontal direction.

[0031] The polishing mechanism 5 includes a housing 7 (the top surface of the housing 7 is transparent to better illustrate the structure of this technical solution). Sliding blocks 8 are connected to both ends of the housing 7 to guide the housing 7 on the frame 1. A drive roller 9 and multiple support rollers 10 are rotatably connected to the housing 7. The multiple support rollers 10 are on the same horizontal plane, and the drive roller 9 is located above the multiple support rollers 10. The input shaft of the drive roller 9 passes through the housing 7 and the frame 1 and is connected to a drive motor 11. The frame 1 has a strip-shaped through hole 12 to avoid the drive motor 11 when the polishing mechanism 5 rises and falls. If the frame 1 is wide, the drive motor 11 can also be installed between the housing 7 and the frame 1. A polishing ring 13 in a tensioned state is connected to the drive roller 9 and the multiple support rollers 10. After the lifting mechanism 6 lowers the polishing mechanism 5, the multiple support rollers 10 press the outer side of the lower part of the polishing ring 13 onto the aluminum material. The polishing ring 13 is driven by the drive roller 9 to rotate outside the drive roller 9 and the multiple support rollers 10 and polishes the aluminum material.

[0032] The multiple support rollers 10 are spaced apart to avoid interference between them.

[0033] The polishing ring 13 includes a flexible ring structure 14 and a polishing connecting part 15 connected to the ring structure 14. The ring structure 14 is a tubular or ring-shaped body woven from high-strength polyester filaments. The polishing connecting part 15 is a square connecting block with polishing material on its surface, such as a rubber sheet with wool felt or cotton cloth adhered to its surface. The polishing connecting part 15 is connected to the outside of the ring structure via connectors 16. The connectors 16 include, but are not limited to, Velcro, rivets, and stitching, as long as they can connect the ring structure 14 and the polishing connecting part 15 and their bodies do not protrude from the surface of the polishing connecting part 15 to cause scratches on the surface of the polished aluminum material. The connectors 16 are staggered.

[0034] The drive roller 9 is evenly distributed with spikes 17 that can penetrate into the ring structure 14. The spikes 17 that penetrate into the ring structure 14 are mainly used to drive the polishing ring 13 to rotate. Example

[0035] Mirror aluminum is a general term encompassing various specifications and requirements, which dictate different surface roughness levels. For instance, in industry, aluminum with a surface roughness of 0.02-0.16 micrometers can be called mirror aluminum. Among these, ordinary mirror finishes typically have a roughness of around 0.08 micrometers, while super mirror finishes require a roughness below 0.05 micrometers.

[0036] In the prior art, the way to change the surface roughness is usually by adjusting the speed at which the aluminum material passes through the polishing mechanism. Although it is possible to adjust the range, the speed at which the aluminum plate passes through is limited. This embodiment proposes to change the polishing effect by changing the contact surface between the polishing mechanism and the aluminum material, thereby increasing the means to control the surface roughness of the aluminum material.

[0037] The technology used in this embodiment is as follows:

[0038] See Figure 1 and Figure 3As shown in the figure, this utility model discloses an automatic polishing device for mirror aluminum plates, including a frame 1. The frame 1 has an "n"-shaped frame with an internal grinding and polishing space. A carrying and conveying mechanism 2 penetrating the grinding and polishing space is provided at the lower part of the frame 1. A coarse grinding mechanism 3, a fine grinding mechanism 4, and a polishing mechanism 5 are sequentially arranged at the upper part of the frame 1 along the transmission direction of the carrying and conveying mechanism 2. The coarse grinding mechanism 3 and the fine grinding mechanism 4 have the same structure as the polishing mechanism 5, or existing coarse grinding and fine grinding mechanisms can be used. A lifting mechanism 6 is connected to the top of the frame 1. The lifting mechanism 6 is a hydraulic telescopic rod or an electric telescopic rod. The output ends of multiple lifting mechanisms 6 pass through the frame 1 and extend into the upper part of the frame 1, and are respectively connected to the top of the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5. The lifting mechanism 6 controls the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5 to rise or fall within the frame 1. The frame 1 is provided with a mechanism to guide the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5, so that the coarse grinding mechanism 3, the fine grinding mechanism 4 and the polishing mechanism 5 can only rise or fall in the vertical direction and cannot deviate in the horizontal direction.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the polishing mechanism 5 includes a housing 7 (the top surface of the housing 7 is transparent to better illustrate the structure of this technical solution). Sliding blocks 8 are connected to both ends of the housing 7 to guide it on the frame 1. A drive roller 9 and multiple support rollers 10 are rotatably connected to the housing 7. The multiple support rollers 10 are connected to the same arc-shaped surface via an arc-shaped tensioner 18. The drive roller 9 is located above the multiple support rollers 10. The input shaft of the drive roller 9 passes through the housing 7 and the frame 1 and is connected to a drive motor 11. The frame 1 has a strip-shaped through hole 12, which is used to avoid the drive motor 11 when the polishing mechanism 5 rises and falls. If the frame 1 is wide, the drive motor 11 can also be installed between the housing 7 and the frame 1. The drive roller 9 and multiple support rollers 10 are connected to a polishing ring 13 in a tensioned state. After the lifting mechanism 6 lowers the polishing mechanism 5, the multiple support rollers 10 press the outer side of the lower part of the polishing ring 13 onto the aluminum material. The polishing ring 13 is driven by the drive roller 9 to rotate outside the drive roller 9 and multiple support rollers 10 and polishes the aluminum material.

[0040] like Figure 6 As shown, the arc-shaped tensioner 18 is composed of at least one arc-shaped metal plate, and a plurality of support rollers 10 are rotatably connected to the arc-shaped tensioner 18 at equal intervals. The support rollers 10 located on the outermost sides are connected to the drive roller 9 by connecting rods 19 with bearings at both ends. The housing 7 is provided with a guide mechanism 20 for guiding the support roller 10 located in the middle.

[0041] The arc-shaped tensioner 18 utilizes the elasticity of the arc-shaped metal plate to achieve pressure on the aluminum material and change the contact area between the polishing ring 13 and the aluminum material. The pressure can be adjusted according to the size and material of different arc-shaped metal plates.

[0042] The guide mechanism 20 is a vertically arranged elongated hole or groove. The two ends of the middle support roller 10 among the multiple support rollers 10 are respectively located inside the guide mechanism 20 and slide along the guide mechanism 20.

[0043] The multiple support rollers 10 are spaced apart to avoid interference between them.

[0044] like Figure 8 As shown, the polishing ring 13 includes a flexible ring structure 14 and a polishing connecting part 15 connected to the ring structure 14. The polishing connecting part 15 is a square connecting block with polishing material on its surface, such as a rubber sheet with wool felt or cotton cloth glued to its surface. The polishing connecting part 15 is connected to the outside of the ring structure 14 via a connector 16. The connector 16 includes, but is not limited to, Velcro, rivets, and stitching, as long as it can connect the ring structure 14 and the polishing connecting part 15 and its body does not protrude from the surface of the polishing connecting part 15 to cause scratches on the surface of the polished aluminum material. The connectors 16 are staggered.

[0045] like Figure 7 As shown, the drive roller 9 is evenly distributed with spikes 17 that can penetrate into the ring structure 14. The spikes 17 that penetrate into the ring structure 14 are mainly used to drive the polishing ring 13 to rotate. The length of the spikes 17 is less than the thickness of the ring structure 14.

[0046] The operating principle of this embodiment is as follows:

[0047] During aluminum plate polishing, the lifting mechanism 6 presses the polishing mechanism 5 downwards. For aluminum materials with less demanding polishing requirements, the downward pressure can be smaller. At this time, the arc-shaped tensioner remains arc-shaped, but the central support roller 10 applies pressure to the aluminum material, and the top polishing ring 13 polishes the aluminum material. When the polishing requirements are higher, the lifting mechanism 6 presses down more. At this time, the arc-shaped tensioner 18 deforms under pressure, causing multiple support rollers 10 to contact the aluminum material downwards. Multiple support rollers 10 apply pressure to the aluminum material, and the top polishing ring 13 polishes the aluminum material, increasing the contact area between the polishing ring and the aluminum material, resulting in a better polishing effect. This embodiment adds a means to adjust the polishing effect of the aluminum material, no longer relying solely on the conveying speed of the aluminum material. This allows the processing speed to be autonomously controlled according to the urgency of the order and the degree of order backlog, making it suitable for industrial production.

[0048] Both of the above embodiments belong to strip online polishing devices, in which the conveying driving force of the aluminum strip comes from the winding device.

[0049] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0050] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to those processes, articles, or apparatus / devices.

[0052] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
