Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and particularly to a surface spraying equipment for aluminum veneer processing. Background Art

[0002] As a lightweight and corrosion-resistant building material, aluminum veneer is widely used in fields such as building curtain walls and interior decoration. Surface spraying can not only enhance its aesthetics but also improve its weather resistance and corrosion resistance. With the development of market demand and technology, the surface spraying equipment for aluminum veneer has been continuously evolving and has become a key link in the production of aluminum veneer. However, there are still some problems in the existing spraying equipment during use, which are as follows:

[0003] The existing spraying equipment has a good spraying effect on aluminum plates with a flat surface. However, for aluminum plates with a certain curvature on the surface, the spraying is very dependent on image acquisition and generation technology, and combined with controlling the nozzle to continuously adjust under the driving mechanism to achieve spraying on the curved surface. However, such a method will cause the entire equipment to overly rely on the effect of the imaging structure and requires a complex control system to achieve. The nozzle of the equipment cannot automatically adjust the distance of the nozzle during moving spraying according to the curved surface of the aluminum plate surface on the placement platform, and thus cannot achieve the effect of adaptive uniform spraying. The overall applicability of the equipment is poor. For this reason, we propose a surface spraying equipment for aluminum veneer processing. Summary of the Invention

Detailed implementation mode

[0031] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure recorded in the following implementation modes are only examples. The surface spraying equipment for aluminum single plates involved in the present invention is not limited to the structures recorded in the following implementation modes. All other implementation modes obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Please refer to Figure 1-2 , a surface spraying equipment for aluminum single plate processing, including a base 1, a carrying component 2 is fixedly installed on the base 1, a connecting support arm 3 is fixedly installed on one side of the base 1, the top end of the connecting support arm 3 is fixedly connected with a top seat 4, a driven component 5 is fixedly connected to the top seat 4, an upper carrying component 6 is fixedly installed on the side surface of the connecting support arm 3, an adaptive component 7 is embedded and movably installed in the upper carrying component 6, a clamping and locking component 8 is fixedly installed at the top end of the upper carrying component 6, a lower carrying plate 9 is fixedly installed on the side surface of the connecting support arm 3, a linear motor structure 10 is fixedly installed at the bottom end of the upper carrying component 6, an adaptive nozzle component 11 is movably installed on the linear motor structure 10, and a coating feeding structure 12 is fixedly installed at the top end of the top seat 4;

[0033] In this embodiment, it should be noted that by providing a bearing component 2, an adaptive system is formed by using the bearing component 2 and the driven component 5. In this way, when an aluminum plate is placed on the bearing component 2 and compressed, gas flows, thereby driving the driven component 5 to extend. The extension of the driven component 5 will automatically synchronously extend by a corresponding distance according to the pressing distance of the aluminum plate surface on the bearing component 2. In this way, multiple driven components 5 above can form a structure with the same curved surface distribution as the aluminum plate surface. Then, by means of the magnetic repulsion effect, the adaptive nozzle assembly 11 can automatically adjust its distance from the aluminum plate surface during movement. In this way, it is realized that the device can adaptively spray different aluminum plate curved surfaces, greatly improving the applicability of the device and reducing the dependence of the device on the image acquisition device. It is more convenient and efficient to use and can be used without too much adjustment. By providing an adaptive component 7 that can freely move up and down between the driven components 5, it is possible to avoid the structure of the driven components 5 being too dense while ensuring the basic display of the curved surface of the aluminum plate surface by the driven components 5. Combining the automatic up and down movement of the adaptive component 7 between the driven components 5 can enable it to automatically adaptively fill the positions of the internal gaps of the driven components 5 to ensure that the entire device can automatically form a complete and coherent magnetic repulsion force drive for the adaptive nozzle assembly 11 moving below, so as to ensure that the adaptive nozzle assembly 11 can stably form a uniform spraying effect on the aluminum plate surface.

[0034] Please refer to Figure 1-2 , a surface spraying device for aluminum veneer processing, including an upper bearing component 6 and a lower bearing plate 9. The upper bearing component 6 passes through the adaptive component 7 and is fixedly connected to the connecting arm 3. The lower bearing plate 9 passes through the bearing component 2 and is fixedly connected to the connecting arm 3. There is a space between the upper bearing component 6 and the top seat 4. The clamping and locking component 8 is installed in the space between the upper bearing component 6 and the top seat 4. The bearing component 2 and the driven component 5 are connected through a gas guide hose in a through manner, and the gas guide hose is placed in the connecting arm 3. The connecting arm 3 is a telescopic hollow structure;

[0035] In this embodiment, it should be noted that in this way, the upper bearing component 6 and the lower bearing plate 9 can be used to ensure the stability of the driven component 5 and the bearing component 2, thereby ensuring the stability of the support of the aluminum plate by the lower bearing component 2. At the same time, it can also ensure the stability of the movement of the top driven component 5 and the adaptive component 7, and then ensure the stability of the movement of the adaptive nozzle assembly 11. In this way, effective, stable and uniform spraying can be realized, and the spraying effect on the aluminum plate surface can be ensured.

[0036] Please refer to Figure 1-3, A surface spraying device for aluminum single-board processing, including a bearing assembly 2. The bearing assembly 2 includes an outer cylinder body 21. An inner airbag 22 is fixedly installed inside the outer cylinder body 21. A supporting top rod 23 is movably installed at the top of the outer cylinder body 21. A pressing ring 24 is fixedly installed at the bottom end of the supporting top rod 23. A first spring 25 is movably sleeved on the supporting top rod 23;

[0037] In this embodiment, it should be noted that the number of the outer cylinder bodies 21 is multiple and evenly arranged. The bottom ends of the outer cylinder bodies 21 are fixedly installed by being embedded inside the base 1. The bottom end of the inner airbag 22 is hermetically connected to the air guide hose in a penetrating manner. The inner airbag 22 and the driven assembly 5 are hermetically filled with gas through the air guide hose. A semi-circular support head is arranged at the top end of the supporting top rod 23. The pressing ring 24 is arranged in a fitting manner with the top end of the inner airbag 22. The first spring 25 is arranged between the inside of the outer cylinder body 21 and the top end of the pressing ring 24. The first spring 25 is always in a stretched state during use. In this way, when the aluminum plate is placed, the self-weight of the aluminum plate can be used to move the first spring 25 downward and stretch it by the multiple evenly arranged supporting top rods 23. During the stretching process, the inner airbag 22 will be compressed, and then the internal gas can be conducted to the inside of the driven assembly 5 through the air guide hose. Furthermore, the driven assembly 5 can be synchronously telescoped. In this way, the self-weight of the aluminum plate can be used to press down the supporting top rod 23 to realize the synchronous movement of the driven assembly 5 at the top. Then, a structural layout that is completely consistent with the curved surface and plane of the aluminum plate surface is formed at the top by multiple driven assemblies 5. Furthermore, when the subsequent adaptive nozzle assembly 11 moves for spraying, the distance can be adjusted adaptively according to the curved surface change of the aluminum plate surface to ensure a uniform spraying effect.

[0038] Please refer to Figure 1-4 , A surface spraying device for aluminum single-board processing, including a driven assembly 5. The driven assembly 5 includes an air inlet cylinder 51. A first permanent magnet block 52 is movably installed at the bottom end of the air inlet cylinder 51. A first extended short board 53 is fixedly installed above the first permanent magnet block 52. A elastic cord 54 is fixedly connected to the bottom end of the first permanent magnet block 52;

[0039] In this embodiment, it should be noted that the top end of the air intake cylinder 51 is hermetically connected to the air guide hose in a penetrating manner. The top end of the first permanent magnet block 52 is arranged inside the air intake cylinder 51 through a piston rod. A driven airbag is arranged inside the air intake cylinder 51 and is hermetically connected to the top end of the air intake cylinder 51. The end of the piston rod is attached to the driven airbag. The first extended short plate 53 is arranged coplanarly with the sides on both sides of the top end of the first permanent magnet block 52. The elastic ropes 54 are connected in pairs between two adjacent first permanent magnet blocks 52 and are supported at the bottom end of the adaptive component 7. In this way, after the aluminum plate at the bottom is placed on the bearing component 2, the weight of the aluminum plate itself can be used to press down the bearing component 2, and the curved surface structure on it will also press down the bearing component 2 at the corresponding position by a corresponding distance, so as to realize the synchronous extension of the first permanent magnet block 52 at the top by a corresponding length. In this way, the device realizes the simple and efficient arrangement of the first permanent magnet block 52 with a comprehensive corresponding surface change by using the self-weight of the aluminum plate, thereby ensuring that the subsequent moving spraying of the adaptive spray head component 11 can adapt to this change to adjust the spraying distance, reflecting the efficient and convenient use effect of the device.

[0040] Please refer to Figure 1-8 , a surface spraying device for aluminum single plates, including an upper bearing component 6. The upper bearing component 6 includes an upper bearing plate 61. A plurality of through holes 62 are formed in the upper bearing plate 61. One end of the bottom end of the upper bearing plate 61 is fixedly installed with a guide rod 63;

[0041] In this embodiment, it should be noted that one side of the upper bearing plate 61 is fixedly connected to the connecting support arm 3. The driven component 5 is installed and limited through the through hole 62. The bottom end of the guide rod 63 is provided with a circular guide hole and is connected to the adaptive spray head component 11 in a penetrating manner. The inner surface of the circular guide hole is a smooth surface structure. The linear motor structure 10 is fixedly installed on both sides of the lower surface of the upper bearing plate 61 respectively. In this way, the through hole 62 can ensure the stability of the overall structure of the driven component 5, thereby ensuring that there is no shaking during the use of the device, and further ensuring the stability and uniformity of the adaptive spray head component 11 during the paint spraying process. At the same time, the side guide rod 63 can ensure the stable and reliable supply of paint during the movement of the adaptive spray head component 11 to ensure the spraying effect.

[0042] Please refer to Figure 1-5 , a surface spraying device for aluminum single plates, including an adaptive component 7. The adaptive component 7 includes a straight rod 71. The bottom end of the straight rod 71 is fixedly installed with a second permanent magnet block 72. The upper surface of the second permanent magnet block 72 is fixedly installed with a second extended short plate 73;

[0043] In this embodiment, it should be noted that a threaded groove is provided on the straight rod 71. An embedded roller is provided on the side surface of the second permanent magnet block 72, and the roller corresponds to the positions of the second extended short board 73 and the first extended short board 53. The top end of the straight rod 71 is provided with a detachable snap connection with the clamping and locking assembly 8. The second permanent magnet block 72 is located between two adjacent first permanent magnet blocks 52 and is carried above the elastic cord 54. The number of second permanent magnet blocks 72 carried above each elastic cord 54 can be appropriately increased or decreased according to requirements. The magnetic pole directions of the second permanent magnet block 72 and the first permanent magnet block 52 are the same and the magnetic force magnitudes are exactly the same. In this way, after the driven assembly 5 is compressed by the bottom bearing assembly 2 and adaptively expands and contracts, the elastic cords 54 between two adjacent first permanent magnet blocks 52 will be inclined and stretched to different degrees, so that different degrees of supporting movement of the second permanent magnet block 72 arranged therebetween can be formed. By using the guiding action of the elastic cords 54, a relatively continuous structure between two first permanent magnet blocks 52 can be formed by multiple second permanent magnet blocks 72, so as to ensure that the force received by the subsequent adaptive nozzle assembly 11 during movement can be relatively continuous and stable, thereby ensuring the uniformity of spraying.

[0044] Please refer to Figure 1-7 , a surface spraying device for aluminum veneer processing, including a clamping and locking assembly 8. The clamping and locking assembly 8 includes a vertical plate 81. An electric push rod 82 is fixedly installed on the vertical plate 81. The end of the electric push rod 82 is fixedly installed with a cross bar 83. A long rod 84 is fixedly installed on one side of the cross bar 83. A locking snap ring 85 is fixedly installed on the long rod 84;

[0045] In this embodiment, it should be noted that the bottom end of the vertical plate 81 is fixedly connected to the upper surface of the upper bearing plate 61. The bottom end of the cross bar 83 is slidably arranged on the upper surface of the upper bearing plate 61. The long rod 84 is arranged to penetrate between adjacent straight rods 71. The locking snap ring 85 is arranged corresponding to the position of the straight rod 71 and an internal tooth groove is arranged on the inner surface. The internal tooth groove can be clamped with the threaded groove provided on the straight rod 71. In this way, after the aluminum plate is placed stably, the driven assembly 5 and the adaptive assembly 7 will automatically complete the corresponding adaptive adjustment. Then, by starting the electric push rod 82, the movement of the cross bar 83 and all the locking snap rings 85 can be driven, so that the locking snap ring 85 is clamped into the threaded groove provided on the straight rod 71 to lock the overall vertical movement position of the adaptive assembly 7, so as to ensure that it will not move up and down under the action of subsequent magnetic repulsion force, and ensure that the shape structure formed by the driven assembly 5 and the adaptive assembly 7 can completely restore the curvature of the aluminum plate surface, so as to ensure the uniformity of subsequent painting.

[0046] Please refer to Figure 1-6, a surface spraying device for aluminum veneer processing, including an adaptive nozzle assembly 11. The adaptive nozzle assembly 11 includes a substrate 111. Connecting cantilevers 112 are fixedly installed on both sides of the top end of the substrate 111. A short rod 113 is embedded and movably installed in the substrate 111. A third permanent magnet 114 is fixedly installed at the top end of the short rod 113. Extension blocks 115 are fixedly installed on both sides of the third permanent magnet 114. A second spring 116 is fixedly installed at the bottom end of the extension block 115. A nozzle 117 is fixedly installed at the bottom end of the short rod 113. A material guide pipe 118 is fixedly connected to one end of the third permanent magnet 114;

[0047] In this embodiment, it should be noted that the top end of the connecting cantilever 112 is slidably connected to the linear motor structure 10. The bottom end of the short rod 113 penetrates through the substrate 111 and is arranged below it. The part of the third permanent magnet 114 connecting the material guide pipe 118 is hollow and is hermetically connected to the short rod 113 and the nozzle 117 at the bottom end in a through manner. The rest is a permanent magnet structure, and the magnetic pole at the upper end is arranged to repel the magnetic poles at the bottom ends of the first permanent magnet 52 and the second permanent magnet 72. The bottom end of the second spring 116 is fixedly connected to the upper surface of the substrate 111. The material guide pipe 118 is sleeved on the guide rod 63 and is movably connected, and the end is hermetically connected to the paint feeding structure 12. In this way, the linear motor structure 10 can be used to drive the entire adaptive nozzle assembly 11 to move on it, and the continuous and stable magnetic repulsion force formed by the first permanent magnet 52 and the second permanent magnet 72 can enable the third permanent magnet 114 to move continuously and stably up and down during the movement, thereby realizing the drive of the nozzle 117 at the bottom to adjust the distance. Furthermore, the distance between the nozzle 117 and the aluminum plate can be automatically adjusted while moving for paint spraying, so that the device can conveniently and efficiently achieve the spraying effect.

[0048] Working principle: Place the aluminum plate on the top end of the supporting push rod 23. Under the action of its own weight, the aluminum plate will press down the supporting push rod 23, thereby stretching the first spring 25 inside and simultaneously compressing the inner airbag 22. After the gas in the inner airbag 22 is compressed, it will enter the interior of the air intake cylinder 51 through the air guide hose and cause the driven airbag therein to inflate and expand, thereby driving the first permanent magnet block 52 at the bottom to achieve adjustment of the corresponding position. The greater the curvature of the corresponding position of the aluminum plate, the greater the compression of the inner airbag 22, and the longer the downward movement of the first permanent magnet block 52 at the corresponding position. Combined with the second permanent magnet block 72 arranged in the middle, under the supporting action of the elastic cord 54, it automatically forms a relatively continuous shape with the first permanent magnet blocks 52 on both sides. In this way, when driving the connecting cantilever 112 to move under the drive of the linear motor structure 10, the third permanent magnet block 114 automatically drives the spray head 117 to move down a corresponding distance by using the magnetic repulsion force between the first permanent magnet block 52 and the second permanent magnet block 72. In this way, during the movement and spraying process of the spray head 117, it can automatically adjust the corresponding distance according to the surface depression situation of the aluminum plate, greatly improving the use convenience of the device, simplifying the use operation and also ensuring the spraying effect of the device.
