Description

Technical Field

[0001] The present invention relates to the processing of aluminum plates, and more specifically, to a zebra-patterned aluminum plate and a processing technology thereof. Background Art

[0002] During the processing of aluminum materials, it is usually necessary to coat their surfaces to endow them with required properties and decorative requirements so that they can adapt to different usage environments. Among them, for some aluminum materials, it is necessary to coat zebra-striped patterns on the surfaces of the aluminum materials to meet the requirements of the users. For example, it is used in double-layer glass frames, which are processed from such zebra-patterned aluminum materials.

[0003] When coating and processing zebra-patterned aluminum materials, a coating roller with multiple ring-shaped protrusions is required to coat the surface of the aluminum material. The protruding parts come into contact with the aluminum material to produce coating, while the concave parts between the protrusions do not come into contact with the aluminum material and do not produce coating, thereby forming a striped coating effect and forming zebra-striped coating patterns. However, currently, in the coating process, for a coating roller with multiple ring-shaped protrusions, the width of the ring-shaped protrusions is fixed. To adjust the coating width of several pairs of zebra patterns, it is necessary to reprocess and design the coating roller. If the re-designed zebra pattern width size is for large-scale production, the manufacturing cost of the coating roller can be evenly spread. If it is only for small-scale production or sample testing, the cost will be too high. Therefore, the current fixed coating roller cannot meet the requirement of flexible adjustment and it is difficult to adapt to the actual production and testing needs of enterprises. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a zebra-patterned aluminum plate and a processing technology thereof.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A processing technology for zebra-patterned aluminum plates uses a coating device for coating. The coating device includes a first coating roller and a second coating roller arranged in parallel. A plurality of coating convex rings one are evenly distributed on the outer periphery of the first coating roller, and a plurality of coating convex rings two are evenly distributed on the outer periphery of the second coating roller. The coating convex rings one and the coating convex rings two correspond to each other one by one. The coating convex rings one and the coating convex rings two are used to coat the surface of the aluminum strip, coating the surface of the aluminum strip respectively, and the two coatings at least partially overlap in the width direction to form coating stripes. The second coating roller can be axially adjusted relative to the first coating roller to adjust the width of the coating stripes formed by the two coatings.

[0007] The present invention is further configured such that both ends of the first coating roller are rotationally supported by a first shaft seat, and the first shaft seat is fixed by a frame; both ends of the second coating roller are rotationally supported by a second shaft seat, and the second shaft seat can be adjusted in the circumferential direction.

[0008] The present invention is further configured such that the coating device further includes two sets of adjusting frames, which are respectively installed on both sides of the ends of the first coating roller and the second coating roller; one end of the adjusting frame is rotatably connected to the outside of the first shaft seat through the first deflection shaft, and the other end of the adjusting frame is rotatably connected to the outside of the second shaft seat through the second deflection shaft. The first deflection shaft and the second deflection shaft are parallel to each other and perpendicular to the first coating roller; the adjusting frame can axially deflect around the first deflection shaft, thereby realizing the axial adjustment of the second coating roller.

[0009] The present invention is further configured such that the lower part of the adjusting frame is supported by a support frame, the adjusting frame is fixedly connected with a bracket, and the lower part of the bracket is supported by pressing against the adjusting frame and can slide on the upper side of the support frame;

[0010] The present invention is further configured such that the bracket is provided with an arc-shaped groove, and the axis of the arc-shaped groove coincides with the first deflection shaft; a limiting rod is fixedly connected to the upper part of the support frame, and the limiting rod penetrates upward through the arc-shaped groove and can slide along the arc-shaped groove; an adjusting nut is threadedly connected to the limiting rod, and the adjusting nut is used to lock and fix the bracket and the support frame to each other.

[0011] The present invention is further configured to further include a third coating roller, and a plurality of third coating convex rings are uniformly distributed on the outer periphery of the third coating roller. The third coating convex rings correspond to the first coating convex rings and the second coating convex rings one by one. The third coating roller can coat on the coated stripe surface of the aluminum strip, and the coating position corresponds to the position where the two coatings overlap.

[0012] The present invention is further configured such that the third coating roller is located between the first coating roller and the second coating roller. The third coating roller can follow the axial adjustment of the second coating roller, and moreover, the axial adjustment amount is half of the adjustment amount of the second coating roller.

[0013] The present invention is further configured such that both ends of the third coating roller are rotatably supported by third shaft seats respectively. The third shaft seats are rotatably connected to the adjusting frame through third deflection shafts. Moreover, the axis of the third deflection shaft is parallel to the axes of the first deflection shaft and the second deflection shaft; and the axis of the third deflection shaft is located in the middle of the axes of the first deflection shaft and the second deflection shaft.

[0014] The present invention is further configured such that the third coating roller is vertically offset from the first coating roller and the second coating roller. The first coating roller and the second coating roller are used for coating the inlet side of the aluminum strip, and the third coating roller is used for coating the outlet side of the aluminum strip.

[0015] The present invention is further configured to further include a support roller, which is used for rolling support of the aluminum strip. A plurality of support convex rings are uniformly distributed on the outer periphery of the support roller, and support gaps are formed between adjacent support convex rings. The coated stripes coated on the surface of the aluminum strip correspond to the support gaps.

[0016] The present invention also discloses a zebra-striped aluminum sheet, which is processed by the zebra-striped aluminum sheet processing process as described above, and a strip-shaped aluminum material with coating stripes can be processed. Moreover, the width of the coating stripes can be finely adjusted according to the required specifications.

[0017] In summary, the present invention has the following beneficial effects:

[0018] The second coating roller can be axially adjusted relative to the first coating roller, and the width of the coating stripes formed by the two coatings can be adjusted. When the coating stripes of the two coatings completely overlap, the width of the finally formed coating stripes is the narrowest and is the same as the width of a single coating; by axially adjusting the second coating roller, the stripes of the two coatings will shift relative to each other, thereby increasing the width of the coating stripes; by coating on both sides of the two coating rollers and adjusting the coating amount of the overlapping part, the final width of the coating stripes generated by coating can be controlled, and thus the coating width of the coating stripes can be flexibly adjusted.

[0019] Through the third coating convex ring, the overlapping position after the two coatings can be roll-coated again, so that the coating material at the overlapping position of the two coatings can be made uniform. Part of the coated slurry can flow from the overlapping position of the coatings to the positions on both sides of the coating stripes, so that the distribution thickness of the coating slurry can be kept relatively uniform. Of course, the uniformity and flowing of the above slurry are all within the width range of the coating stripes. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] This embodiment discloses a processing technology for zebra-striped aluminum sheets. Through this technology, the aluminum material is coated to form zebra-striped aluminum sheets. Refer to Figure 1 as shown.

[0030] Refer to Figure 1 as shown. A plurality of coating stripes 101 are coated on the surface of the zebra-striped aluminum sheet. The coating stripes 101 are evenly and parallel to each other, and the coating stripes 101 are arranged along the length direction of the aluminum material. The aluminum material has a metallic luster, and the coating stripes 101 are black stripes, forming a zebra-like structure.

[0031] Refer to Figures 2 - 7 as shown. A coating device is used for coating. The coating device includes a coating roller 1 2 and a coating roller 2 3 that are arranged parallel to each other. During the coating process of the aluminum material surface, the aluminum strip can be coated twice. A plurality of coating projection rings 1 201 are evenly distributed on the outer periphery of the coating roller 1 2, and a plurality of coating projection rings 2 301 are evenly distributed on the outer periphery of the coating roller 2 3. The coating projection rings 1 201 and the coating projection rings 2 301 correspond to each other one by one. The coating projection rings 1 201 and the coating projection rings 2 301 have the same width, and the quantity and position also correspond to each other one by one.

[0032] During the coating process, the coating projection rings 1 201 and the coating projection rings 2 301 can contact the surface of the aluminum sheet, and can coat the surface of the strip-shaped aluminum plate. By coating on both sides of the coating projection rings 1 201 and the coating projection rings 2 301, two coating stripes 101 can be formed on the surface of the aluminum strip, and the two coatings at least partially overlap each other in the width direction to form the coating stripes 101.

[0033] The coating roller II 3 can be axially adjusted relative to the coating roller I 2, and the width of the coating stripes 101 formed by the two coatings can be adjusted. When the coating stripes 101 of the two coatings completely overlap, the width of the finally formed coating stripes 101 is the narrowest and is the same as the width of a single coating; by axially adjusting the coating roller II 3, the stripes of the two coatings will shift relative to each other, thereby increasing the width of the coating stripes 101. The maximum width can be adjusted to twice the width of a single coating. If the width of the coating stripes 101 during a single coating is a; during two coatings, the width range of the coating stripes 101 is (a, 2a). Generally, the range of the two coatings is usually (1.2a, 1.8a).

[0034] Both ends of the coating roller I 2 are rotatably supported by the first shaft seats 21, and the first shaft seats 21 are fixed by the machine frame. Both ends of the coating roller II 3 are rotatably supported by the second shaft seats 31, and the second shaft seats 31 can be adjusted in the circumferential direction. By axially adjusting the second shaft seats 31 to achieve axial adjustment of the coating roller II 3, for the width of the coating stripes 101, the adjustment range of the coating roller II 3 can be adjusted to achieve adjustment control.

[0035] In addition, the coating device further includes two sets of adjusting frames 6, which are respectively installed on both sides of the ends of the coating roller I 2 and the coating roller II 3, and the coating roller II 3 is axially adjusted by the two sets of adjusting frames 6. One end of the adjusting frame 6 is rotatably connected to the outside of the first shaft seat 21 through the first deflection shaft 22, and the other end of the adjusting frame 6 is rotatably connected to the outside of the second shaft seat 31 through the second deflection shaft 32.

[0036] The axes of the first deflection shaft 22 and the second deflection shaft 32 are parallel to each other and perpendicular to the coating roller I 2. The adjusting frame 6 can be axially deflected around the first deflection shaft 22, thereby realizing axial adjustment of the coating roller II 3. The first deflection shaft 22, the second deflection shaft 32 and the two adjusting frames 6 are hinged to form a parallelogram structure, which can be rotated and adjusted around the first deflection shaft 22 and the second deflection shaft 32. During the adjustment process, the axial adjustment of the coating roller II 3 can be carried out, the axial position between the coating roller I 2 and the coating roller II 3 can be adjusted, and the offset of the coating stripes 101 of the two coatings can be adjusted, thereby being able to adjust the width of the zebra stripes finally formed by the coating stripes 101.

[0037] Refer to Figure 5 As shown, the coating roller I 2 and the coating roller II 3 are arranged at the same height, and the inlet side 11 of the aluminum strip 1 bypasses the lower sides of the coating roller II 3 and the coating roller I 2, and the inlet side 11 of the aluminum strip 1 remains substantially horizontal. In order to maintain the coating tightness between the coating roller I 2, the coating roller II 3 and the aluminum strip, support wheels can be installed at the lower side position of the aluminum strip 1, thereby being able to maintain the pressure between the aluminum strip 1 and the coating roller I 2 and the coating roller II 3 and maintain the stability of the coating.

[0038] The lower part of the adjusting frame 6 is supported by the support frame 7. The adjusting frame 6 is fixedly connected with a bracket 61. The lower part of the bracket 61 is supported by being pressed against the support frame 7 and can slide on the upper side of the support frame 7. By laterally offsetting the bracket 61 on the upper side of the support frame 7, the axial offset of the second coating roller 3 can be realized.

[0039] Specifically, an arc-shaped groove 62 is formed in the bracket 61, and the axis of the arc-shaped groove 62 coincides with the first deflection shaft 22. The upper part of the support frame 7 is fixedly connected with a limit rod 63. The limit rod 63 penetrates upward through the arc-shaped groove 62 and can slide along the arc-shaped groove 62. The running direction of the limit rod 63 is consistent with that of the arc-shaped groove 62, so as to guide the deflection of the adjusting frame 6.

[0040] In addition, a locking nut 64 is threadedly connected to the limit rod 63. By adjusting the locking nut 64 through threading, the threaded rotation of the locking nut 64 can lock and fix the bracket 61 and the support frame 7 to each other. When adjustment is needed, the locking nut 64 can be loosened through threading, and then the deflection adjustment of the limit rod 63 can be carried out.

[0041] The coating device further includes a support roller 5, and the support roller 5 can roll and support the aluminum strip 1. A plurality of support convex rings 51 are evenly distributed on the outer circumference of the support roller 5. A support gap 52 is formed between adjacent support convex rings 51, and the coating stripes 101 coated on the surface of the aluminum strip 1 correspond to the support gaps 52. The coated aluminum strip can be supported by the support convex rings 51, and the coating stripes 101 can fall into the support gaps 52, avoiding scratching the coating stripes 101 and maintaining the flatness of the edge.

[0042] Furthermore, the coating device in this embodiment further includes a third coating roller 4, and a plurality of third coating convex rings 401 are evenly distributed on the outer circumference of the third coating roller 4. The shape of the third coating roller 4 is the same as that of the first coating roller 2 and the second coating roller 3. The third coating convex rings 401 correspond one by one to the first coating convex rings 201 and the second coating convex rings 301, and the width, quantity and position all correspond one by one.

[0043] The third coating roller 4 can coat on the surface of the coating stripes 101 of the aluminum strip. Among them, during the coating process of the first coating roller 2 and the second coating roller 3, the required coating can be coated on the surface of the aluminum material. The third coating roller 4 does not increase the coating, but only makes the positions of the third coating convex rings 401 on the third coating roller 4 correspond to the overlapping positions of the two coatings, that is, the positions of the third coating convex rings 401 correspond thereto.

[0044] By coating the convex ring III 401, the overlapping position after two coatings can be roll-coated again, so that the coating material at the overlapping position of the two coatings can be made uniform. Part of the coated slurry can flow from the overlapping position of the coatings to both sides of the coating stripe 101, so that the distribution thickness of the coated slurry can be kept relatively uniform. Of course, the uniformity and flow of the above-mentioned slurry are within the width range of the coating stripe 101.

[0045] The coating roller III 4 is located between the coating roller I 2 and the coating roller II 3. The coating roller III 4 can follow the axial adjustment of the coating roller II 3, and the axial adjustment amount is half of the adjustment amount of the coating roller II 3. By controlling the axial offset amount of the coating roller III 4, the convex ring III 401 on the outer periphery of the coating roller III 4 can always be correspondingly roll-pressed at the overlapping part of the stripes of the two coatings, and can effectively and stably play the role of making the coated slurry uniform.

[0046] Specifically, both ends of the coating roller III 4 are rotatably supported by the axle seats III 41, and the axle seats III 41 are rotatably connected to the adjusting frame 6 through the deflecting shafts III 42. And the axis of the deflecting shaft III 42 is parallel to the axes of the deflecting shaft I 22 and the deflecting shaft II 32, and the axis of the deflecting shaft III 42 is located in the middle of the axes of the deflecting shaft I 22 and the deflecting shaft II 32.

[0047] During the axial adjustment of the coating roller II 3, it can automatically drive the axial adjustment of the coating roller III 4, so that the coating roller III 4 can automatically follow the coating roller II 3 to produce a linkage, and then the adjustment position of the coating roller III 4 can meet the needs of coating.

[0048] A fixing frame 65 is fixedly connected to the upper side of the middle position of the adjusting frame 6. The axle seats III 41 at both ends of the coating roller III 4 are rotatably connected to the fixing frame 65, so that the coating roller III 4 is vertically offset from the coating roller I 2 and the coating roller II 3. Among them, the lower sides of the coating roller I 2 and the coating roller II 3 are in contact with the inlet side 11 of the aluminum strip 1, and the upper side of the inlet side 11 of the aluminum strip 1 is coated; the upper side of the coating roller III 4 is in contact with the outlet side of the aluminum strip 1, and the middle position of the coating stripe 101 after coating is roll-pressed to make the coated slurry uniform.

[0049] This embodiment also discloses a zebra-striped aluminum sheet. By using the zebra-striped aluminum sheet processing process as described above, a strip-shaped aluminum material with coating stripes 101 can be processed, and the width of the coating stripes 101 can be finely adjusted according to the required specifications.

[0050] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
